A conflict of interest (COI) is a situation in which a person or organization is involved in multiple interests, financial or otherwise, and serving one interest could involve working against another. Typically, this relates to situations in which the personal interest of an individual or organization might adversely affect a duty owed to make decisions for the benefit of a third party.
An "interest" is a commitment, obligation, duty or goal associated with a particular social role or practice. By definition, a "conflict of interest" occurs if, within a particular decision-making context, an individual is subject to two coexisting interests that are in direct conflict with each other. Such a matter is of importance because under such circumstances the decision-making process can be disrupted or compromised in a manner that affects the integrity or the reliability of the outcomes.
Typically, a conflict of interest arises when an individual finds himself or herself occupying two social roles simultaneously which generate opposing benefits or loyalties. The interests involved can be pecuniary or non-pecuniary. The existence of such conflicts is an objective fact, not a state of mind, and does not in itself indicate any lapse or moral error. However, especially where a decision is being taken in a fiduciary context, it is important that the contending interests be clearly identified and the process for separating them is rigorously established. Typically, this will involve the conflicted individual either giving up one of the conflicting roles or else recusing himself or herself from the particular decision-making process that is in question.
The presence of a conflict of interest is independent of the occurrence of Inappropriateness. Therefore, a conflict of interest can be discovered and voluntarily defused before any corruption occurs. A conflict of interest exists if the circumstances are reasonably believed (on the basis of past experience and objective evidence) to create a risk that a decision may be unduly influenced by other, secondary interests, and not on whether a particular individual is actually influenced by a secondary interest.
A widely used definition is: "A conflict of interest is a set of circumstances that creates a risk that professional judgement or actions regarding a primary interest will be unduly influenced by a secondary interest." Primary interest refers to the principal goals of the profession or activity, such as the protection of clients, the health of patients, the integrity of research, and the duties of public officer. Secondary interest includes personal benefit and is not limited to only financial gain but also such motives as the desire for professional advancement, or the wish to do favours for family and friends. These secondary interests are not treated as wrong in and of themselves, but become objectionable when they are believed to have greater weight than the primary interests. Conflict of interest rules in the public sphere mainly focus on financial relationships since they are relatively more objective, fungible, and quantifiable, and usually involve the political, legal, and medical fields.
A conflict of interest is a set of conditions in which professional judgment concerning a primary interest (such as a patient's welfare or the validity of research) tends to be unduly influenced by a secondary interest (such as financial gain). Conflict-of-interest rules [...] regulate the disclosure and avoidance of these conditions.
Related to the practice of law
Conflict of interests have been described as the most pervasive issue facing modern lawyers.
 Legal conflicts rules are at their core corollaries to a lawyer’s two 
basic fiduciary duties: (1) the duty of loyalty and (2) the duty to 
preserve client confidences.
 The lawyer’s duty of loyalty is fundamental to the attorney-client 
relationship and has developed from the biblical maxim that no person 
can serve more than one master.
 Just as fundamental is the lawyer’s duty to maintain client 
confidences, which protects clients’ legitimate expectations that they 
can make full disclosure of all facts to their attorneys without fear of
 exposure.
The basic formulation of the conflicts of interest rule is that a
 conflict exists “if there is a substantial risk that the lawyer’s 
representation of the client would be materially and adversely affected 
by the lawyer’s own interests or by the lawyers’ duties to another 
current client, a former client, or a third person.”
 The duty of loyalty requires an attorney not to act directly adverse to
 an existing client, even on an unrelated matter where the lawyer has no
 client confidences. Such a loyalty conflict has been labeled a concurrent conflict of interest. The duty of confidentiality is protected in rules prohibiting so-called successive conflicts of interest, when a lawyer proposes to act adversely to the interests of a former client.
 A lawyer who has formerly represented a client in a matter is precluded
 from representing another person in the same or a substantially related
 matter that is materially adverse to the former client.
 These two basic formulations – that a lawyer may not act directly 
adverse to a current client or adverse to a former client on a 
substantially related matter – form the cornerstone of modern legal 
conflicts of interest rules.
Concurrent Conflicts of Interest
Direct Adversity to Current Client
An attorney owes the client undivided loyalty. The courts have described this principle as “integral to the nature of an attorney’s duty.”
 Without undivided loyalty, irreparable damage may be done “to the 
existing client’s sense of trust and security – features essential to 
the effective functioning of the fiduciary relationship…”
 A key feature of the duty of loyalty is that an attorney may not act 
directly adverse to a current client or represent a litigation adversary
 of the client in an unrelated matter. The damage done is to the client’s confidence that the lawyer is serving his or her interests faithfully. The most obvious example of a lawyer acting directly adverse to a client is when the lawyer sues the client.
 At the other end of the spectrum is when a lawyer represents business 
competitors of the client who are not adverse to it in a lawsuit or 
negotiation. Representing business competitors of a client in unrelated 
matters does not constitute direct adversity nor give rise to a loyalty 
conflict. As one state bar ethics committee has noted: 
An attorney's 
representation of one client will often have indirect effects on other 
existing clients. For example, simultaneously representing business 
competitors on unrelated matters may indirectly impair the interests of 
each. It will be rare indeed when an attorney's representation of a 
client will not have numerous indirect adverse effects on others. 
Obtaining a benefit for a client will often mean disadvantaging another 
person or entity, and indirect consequences may follow to all who may be
 dependents or owners of the attorney's opponents.
The attorney's duty of loyalty, however, extends only to adverse 
consequences on existing clients which are ‘direct.’…Of the numerous and
 varied consequences which a representation of one client may have on 
other clients, well-established legal authority interpreting the duty of
 loyalty limits the scope of ethical inquiry to whether the other 
affected clients are parties to the case or transaction in which the 
attorney is acting.
--CALIFORNIA STATE BAR ETHICS OPINION 1989-113.
--CALIFORNIA STATE BAR ETHICS OPINION 1989-113.
Direct adversity may arise in litigation when an attorney sues a 
client or defends an adversary in an action his or her client has 
brought.
 It may also arise in the context of business negotiations, when a 
lawyer negotiates on behalf of an adversary against a current client, 
even if the matter is unrelated to any matter the lawyer is handling for
 the client. However, merely advocating opposite sides of the same legal issue does not give rise to direct adversity.
 Even if a lawyer’s advocacy in an unrelated matter may make unfavorable
 law for another client, such effects are only indirect and not subject 
to the conflicts rules.
 There is no conflict in advocating positions that may turn out to be 
unfavorable to another client so long as the lawyer is not directly 
litigating or negotiating against that client.
Identity of the Client - Corporations
One
 of the most frequently arising questions in corporate practice is 
whether parent corporations and their subsidiaries are to be treated as 
the same or different entities for conflicts purposes.
 The first authority to rule on this question was the California State 
Bar Ethics Committee, which issued a formal opinion ruling that parent 
corporations and their subsidiaries are to be considered distinct 
entities for conflicts purposes.
 The California committee considered a situation where an attorney 
undertook a representation directly adverse to the wholly owned 
subsidiary of a client, when the lawyer did not represent the 
subsidiary. Relying on the entity as client framework in Model Rule 1.13,
 the California committee opined that there was no conflict as long as 
the parent and subsidiary did not have a “sufficient unity of 
interests.” The committee announced the following standard for evaluating the separateness of parent and subsidiary:
In determining whether there is a sufficient unity of interests to require an attorney to disregard separate corporate entities for conflict purposes, the attorney should evaluate the separateness of the entities involved, whether corporate formalities are observed, the extent to which each entity has distinct and independent managements and board of directors, and whether, for legal purposes, one entity could be considered the alter ego of the other. -CALIFORNIA STATE BAR ETHICS OPINION 1989-113.
As one commentator has noted, “For a state ethics opinion, California
 Opinion 1989-113 has been unusually influential, both with courts 
there, with ethics committees elsewhere, and through the latter set of 
ethics committee opinions, with…recent decisions in other 
jurisdictions.”
 The California opinion has been followed by ethics committees in such 
jurisdictions as New York, Illinois and the District of Columbia, and 
served as the basis of ABA Formal Ethics Opinion 95-390.
 The law in most jurisdictions is that parent corporations and their 
subsidiaries are treated as distinct entities, except in limited 
circumstances noted by the California ethics committee where they have a
 unity of interests.
The Second Circuit has adopted a variation of the California standard. In GSI Commerce Solutions, Inc. v. BabyCenter LLC,
 the court ruled that parent corporations and their subsidiaries should 
be treated as the same entity for conflicts purposes when both companies
 rely “on the same in-house legal department to handle their legal 
affairs.” However, the court ruled that the lawyer and client can contract around this default standard.
 The court quoted with approval the opinion of the City of New York 
Committee on Professional and Judicial Ethics, which stated, “corporate 
family conflicts may be averted by . . . an engagement letter . . . that
 delineates which affiliates, if any, of a corporate client the law firm
 represents. . . ."
Material Limitation Conflicts
A concurrent conflict will also exist when “there is a 
significant risk that the representation of one or more clients will be 
materially limited by the lawyer's responsibilities to another client, a
 former client or a third person or by a personal interest of the 
lawyer.”
 Comment 8 to Model Rule 1.7 states, by way of example, that an attorney
 representing multiple persons forming a joint venture may be materially
 limited in recommending the courses of action that any jointly 
represented client may take because of the lawyer’s duty to the other 
participants in the joint venture.
The Supreme Court of Minnesota found a material limitation conflict in In re Petition for Disciplinary Action Against Christopher Thomas Kalla. In Kalla,
 an attorney was disciplined for representing a borrower bringing suit 
against her lender for charging a usurious interest rate while 
simultaneously representing the mortgage broker who arranged the loan as
 a third party defendant in the same lawsuit. Although neither client 
had brought an action against the other, the court found a material 
limitation conflict: “Advocating for Client A would potentially harm 
Client B, who was potentially liable for contribution. Kalla’s ability 
to fully advocate for both was materially limited by Kalla’s dual 
representation.”
Consent to Concurrent Conflicts of Interest
Consent to Current Conflicts
A concurrent conflict of interest may be resolved if four conditions are met. They are:
- the lawyer reasonably believes that the lawyer will be able to provide competent and diligent representation to each affected client;
- the representation is not prohibited by law;
- the representation does not involve the assertion of a claim by one client against another client represented by the lawyer in the same litigation or other proceeding before a tribunal; and
- each affected client gives informed consent, confirmed in writing.
Informed consent requires that each affected client be fully advised 
about the material ways that the representation could adversely affect 
that client.
 In joint representations, the information provided should include the 
interests of the lawyer and other affected client, the courses of action
 that could be foreclosed due to the joint representation, the potential
 danger that the client’s confidential information might be disclosed, 
and the potential consequences if the lawyer had to withdraw at a later 
stage in the proceedings. Merely telling the client that there are conflicts, without further explanation, is not adequate disclosure.
 The lawyer must fully disclose the potential impairment to the lawyer’s
 loyalty and explain how another unconflicted attorney might better 
serve the client’s interests.
Prospective Consent to Future Conflicts
It
 is not unusual in the current legal environment of large multinational 
and global law firms for the firms to seek advance or prospective 
waivers of future conflicts from their clients.
 A law firm is particularly likely to seek a prospective waiver when a 
large corporation seeks the specialized knowledge of the firm in a small
 matter, without a high likelihood of repeat business. As the ABA stated in its Ethics Opinion 93-372:
when corporate clients with multiple operating divisions hire tens if not hundreds of law firms, the idea that, for example, a corporation in Miami retaining the Florida office of a national law firm to negotiate a lease should preclude that firm’s New York office from taking an adverse position in a totally unrelated commercial dispute against another division of the same corporation strikes some as placing unreasonable limitations on the opportunities of both clients and lawyers. -ABA Formal Opinion 93-372 (1993).
Prospective waivers are most likely to be upheld by the courts when 
they are given by sophisticated corporate clients represented by 
independent counsel in the negotiation of the waiver. However, in Sheppard, Mullin, Richter & Hampton, LLP v. J-M Manufacturing Co.,
 the California Supreme court held that a prospective waiver that did 
not make specific disclosure of an actual current conflict was not 
effective to waive that conflict. As the court said,
By asking J-M to waive current conflicts as well as future ones, Sheppard Mullin did put J-M on notice that a current conflict might exist. But by failing to disclose to J-M the fact that a current conflict actually existed, the law firm failed to disclose to its client all the ‘relevant circumstances’ within its knowledge relating to its representation of J-M. 6 Cal. 5th 59 (2018) at p. 84.
The Sheppard Mullin case does not invalidate prospective waivers in California.
 It only holds that waivers of current and actual conflicts must 
specifically disclose those conflicts, an unremarkable conclusion.
The Hot Potato Doctrine
If a client will not consent to a conflict and allow a lawyer to take on another representation, the lawyer cannot then withdraw from the existing representation, thus turning the existing client into a former client and ending the duty of loyalty. As the courts have stated, the lawyer cannot “drop a client like a hot potato” to cure a conflict. This label has stuck, and the doctrine is now aptly called the “hot potato” doctrine. However, as one commentator has pointed out, the reasoning underlying this line of cases has been sparse, and few courts have attempted to justify this result through an analysis of the ethics rules. The unstated rationale behind the Hot Potato doctrine is that a withdrawal attempted without good cause under Model Rule 1.16(b) is an ineffective withdrawal, which does not successfully terminate the existing attorney-client relationship. When viewed in this light, a withdrawal accomplished with good cause should be an effective withdrawal that does permit a lawyer to take on a representation that would otherwise be conflicting, as long as there is no substantial relationship with the prior matter. The standard used to assess conflicts involving such former clients will be discussed in the next section.
Successive Conflicts of Interest
The Substantial Relationship Test
Conflicts
 of interest rules involving former clients are primarily designed to 
enforce the attorney’s duty to preserve a client’s confidential 
information.
 Model Rule 1.9(a) sets forth this doctrine in a rule that has come to 
be known as the substantial relationship test. The rule states:
A lawyer who has formerly represented a client in a matter shall not thereafter represent another person in the same or a substantially related matter in which that person's interests are materially adverse to the interests of the former client unless the former client gives informed consent, confirmed in writing. -MODEL RULES OF PROF’L CONDUCT r. 1.9(a).
Without the substantial relationship test, a client attempting to 
prove that its former lawyer possesses its confidential information 
might have to disclose publicly the very confidential information it is 
trying to protect. The substantial relationship test was designed to protect against such disclosures.
 Under this test, the attorney’s possession of the former client’s 
confidential information is presumed if "confidential information 
material to the current dispute would normally have been imparted to the
 attorney by virtue of the nature of the former representation."
 The substantial relationship test reconstructs whether confidential 
information was likely to imparted by the former client to the lawyer by
 analyzing “the similarities between the two factual situations, the 
legal questions posed, and the nature and extent of the attorney's 
involvement with the cases."
Imputation of Conflicts
The
 conflicts of an individual lawyer are imputed to all attorneys who “are
 associated with that lawyer in rendering legal services to others 
through a law partnership, professional corporation, sole 
proprietorship, or similar association.”
 This imputation of conflicts can lead to difficulties when attorneys 
from one law firm leave and join another firm. The issue then arises 
whether the conflicts of the itinerant lawyer’s former firm are imputed 
to his or her new firm.
In Kirk v. First American Title Co.,
 the court ruled that an itinerant lawyer’s conflicts are not imputed to
 his or her new law firm if that firm timely sets up an effective ethics
 screen preventing the lawyers from imparting any confidential 
information to the lawyers in the new firm.
 An effective ethics screen rebuts the presumption that the itinerant 
lawyers shared confidential information with the lawyers in the new 
firm. The components of an effective ethics screen, as described by the court in Kirk, are:
- physical, geographic, and departmental separation of attorneys;
- prohibitions against and sanctions for discussing confidential matters;
- established rules and procedures preventing access to confidential information and files;
- procedures preventing a disqualified attorney from sharing in the profits from the representation;
- continuing education in professional responsibility.
Judicial disqualification, also referred to as recusal,
 refers to the act of abstaining from participation in an official 
action such as a court case/legal proceeding due to a conflict of 
interest of the presiding court official or administrative officer. Applicable statutes or canons of ethics
 may provide standards for recusal in a given proceeding or matter. 
Providing that the judge or presiding officer must be free from 
disabling conflicts of interest makes the fairness of the proceedings 
less likely to be questioned.
In the practice of law, the duty of loyalty owed to a client prohibits an attorney (or a law firm)
 from representing any other party with interests adverse to those of a 
current client. The few exceptions to this rule require informed written
 consent from all affected clients, i.e., an "ethical wall". In 
some circumstances, a conflict of interest can never be waived by a 
client. In perhaps the most common example encountered by the general 
public, the same firm should not represent both parties in a divorce or 
child custody matter. Found conflict can lead to denial or disgorgement of legal fees, or in some cases (such as the failure to make mandatory disclosure), criminal proceedings. In 1998, a Milbank, Tweed, Hadley & McCloy partner was found guilty of failing to disclose a conflict of interest, disbarred, and sentenced to 15 months of imprisonment.
 In the United States, a law firm usually cannot represent a client if 
the client's interests conflict with those of another client, even if 
the two clients are represented by separate lawyers within the firm, 
unless (in some jurisdictions) the lawyer is segregated from the rest of
 the firm for the duration of the conflict. Law firms often employ 
software in conjunction with their case management and accounting 
systems in order to meet their duties to monitor their conflict of 
interest exposure and to assist in obtaining waivers.
More
 generally, conflicts of interest can be defined as any situation in 
which an individual or corporation (either private or governmental) is 
in a position to exploit a professional or official capacity in some way
 for their personal or corporate benefit.
Depending upon the law or rules related to a particular 
organization, the existence of a conflict of interest may not, in and of
 itself, be evidence of wrongdoing. In fact, for many professionals, it 
is virtually impossible to avoid having conflicts of interest from time 
to time. A conflict of interest can, however, become a legal matter, for
 example, when an individual tries (and/or succeeds in) influencing the 
outcome of a decision, for personal benefit. A director or executive of a
 corporation will be subject to legal liability if a conflict of 
interest breaches his/her duty of loyalty.
There often is confusion over these two situations. Someone 
accused of a conflict of interest may deny that a conflict exists 
because he/she did not act improperly. In fact, a conflict of interest 
can exist even if there are no improper acts as a result of it. (One way
 to understand this is to use the term "conflict of roles". A person 
with two roles—an individual who owns stock and is also a government
 official, for example—may experience situations where those two roles 
conflict. The conflict can be mitigated—see below—but it still exists. 
In and of itself, having two roles is not illegal, but the differing 
roles will certainly provide an incentive for improper acts in some 
circumstances.)
As an example, in the sphere of business and control, according to the Institute of Internal Auditors:
conflict of interest is a situation in which an internal auditor, who is in a position of trust, has a competing professional or personal interest. Such competing interests can make it difficult to fulfill his or her duties impartially. A conflict of interest exists even if no unethical or improper act results. A conflict of interest can create an appearance of impropriety that can undermine confidence in the internal auditor, the internal audit activity, and the profession. A conflict of interest could impair an individual's ability to perform his or her duties and responsibilities objectively.
Organizational
An organizational conflict of interest (OCI) may exist in the same 
way as described above, for instance where a corporation provides two 
types of service to the government and these services conflict (e.g.: 
manufacturing parts and then participating on a selection committee 
comparing parts manufacturers).
 Corporations may develop simple or complex systems to mitigate the risk
 or perceived risk of a conflict of interest. These risks can be 
evaluated by a government agency (for example, in a U.S. Government RFP)
 to determine whether the risks create a substantial advantage to the 
organization in question over its competition, or will decrease the 
overall competitiveness of the bidding process.
Conflict of interest in the health care industry
The influence of the pharmaceutical industry
 on medical research has been a major cause for concern. In 2009 a study
 found that "a number of academic institutions" do not have clear 
guidelines for relationships between Institutional Review Boards and 
industry.
In contrast to this viewpoint, an article and associated editorial in the New England Journal of Medicine in May 2015
 emphasized the importance of pharmaceutical industry-physician 
interactions for the development of novel treatments, and argued that 
moral outrage over industry malfeasance had unjustifiably led many to 
overemphasize the problems created by financial conflicts of interest.  
The article noted that major healthcare organizations such as National 
Center for Advancing Translational Sciences of the National Institutes 
of Health, the President's Council of Advisors on Science and Technology,
 the World Economic Forum, the Gates Foundation, the Wellcome Trust, and
 the Food and Drug Administration had encouraged greater interactions 
between physicians and industry in order to bring greater benefits to 
patients.
Types
The following are the most common forms of conflicts of interests:
- Self-dealing, in which an official who controls an organization causes it to enter into a transaction with the official, or with another organization that benefits the official only. The official is on both sides of the "deal."
- Outside employment, in which the interests of one job conflict with another.
- Nepotism, in which a spouse, child, or other close relative is employed (or applies for employment) by an individual, or where goods or services are purchased from a relative or from a firm controlled by a relative. To avoid nepotism in hiring, many employment applications ask if the applicant is related to a current employee of the company. This allows recusal if the employed relative has a role in the hiring process. If this is the case, the relative could then recuse from any hiring decisions.
- Gifts from friends who also do business with the person receiving the gifts or from individuals or corporations who do business with the organization in which the gift recipient is employed. Such gifts may include non-tangible things of value such as transportation and lodging.
- Pump and dump, in which a stock broker who owns a security artificially inflates the price by "upgrading" it or spreading rumors, sells the security and adds short position, then "downgrades" the security or spreads negative rumors to push the price down.
Other improper acts that are sometimes classified as conflicts of 
interests may have better classification. For example, accepting bribes can be classified as corruption, use of government or corporate property or assets for personal use is fraud, and unauthorized distribution of confidential information is a security breach. For these improper acts, there is no inherent conflict.
 COI is sometimes termed competition of interest rather than "conflict", emphasizing a connotation of natural competition
 between valid interests—rather than the classical definition of 
conflict, which would include by definition including a victim and 
unfair aggression. Nevertheless, this denotation of conflict of interest is not generally seen.
Examples
Environmental hazards and human health
Baker summarized 176 studies of the potential impact of Bisphenol A on human health as follows:
| Funding | Harm | No Harm | 
|---|---|---|
| Industry | 0 | 13 (100%) | 
| Independent (e.g., government) | 152 (86%) | 11 (14%) | 
Lessig
 noted that this does not mean that the funding source influenced the 
results. However, it does raise questions about the validity of the 
industry-funded studies specifically, because the researchers conducting
 those studies have a conflict of interest; they are subject at minimum 
to a natural human inclination to please the people who paid for their 
work. Lessig provided a similar summary of 326 studies of the potential 
harm from cell phone usage with results that were similar but not as 
stark.
Self-regulation
Self-regulation
 of any group may also be a conflict of interest. If an entity, such as a
 corporation or government bureaucracy, is asked to eliminate unethical 
behavior within their own group, it may be in their interest in the 
short run to eliminate the appearance of unethical behavior, rather than
 the behavior itself, by keeping any ethical breaches hidden, instead of
 exposing and correcting them. An exception occurs when the ethical 
breach is already known by the public. In that case, it could be in the 
group's interest to end the ethical problem to which the public has 
knowledge, but keep remaining breaches hidden.
Insurance claims adjusters
Insurance companies retain claims adjusters
 to represent their interest in adjusting claims. It is in the best 
interest of the insurance companies that the very smallest settlement is
 reached with its claimants. Based on the adjuster's experience and 
knowledge of the insurance policy it is very easy for the adjuster to 
convince an unknowing claimant to settle for less than what they may 
otherwise be entitled which could be a larger settlement. There is 
always a very good chance of a conflict of interest to exist when one 
adjuster tries to represent both sides of a financial transaction such 
as an insurance claim. This problem is exacerbated when the claimant is 
told, or believes, the insurance company's claims adjuster
 is fair and impartial enough to satisfy both theirs and the insurance 
company's interests. These types of conflicts could easily be avoided by
 the use of a third party platform that is independent of the insurers 
and is agreed to, and named in the policy.
Purchasing agents and sales personnel
A
 person working as the equipment purchaser for a company may get a bonus
 proportionate to the amount he's under budget by year end. However, 
this becomes an incentive for him to purchase inexpensive, substandard 
equipment. Therefore, this is counter to the interests of those in his 
company who must actually use the equipment. W. Edwards Deming listed "purchasing on price alone" as number 4 of his famous 14 points, and he often said things to the effect that "He who purchases on price alone deserves to get rooked."
Government officials
Conflict
 of interest in legislation; the interests of the poor and the interests
 of the rich. A personification of corrupt legislation weighs a bag of 
money and denies an appeal of poverty.
Regulating conflict of interest in government is one of the aims of political ethics.
 Public officials are expected to put service to the public and their 
constituents ahead of their personal interests. Conflict of interest 
rules are intended to prevent officials from making decisions in 
circumstances that could reasonably be perceived as violating this duty 
of office. Rules in the executive branch tend to be stricter and easier 
to enforce than in the legislative branch. Two problems make legislative ethics of conflicts difficult and distinctive.
 First, as James Madison wrote, legislators should share a "communion of
 interests" with their constituents. Legislators cannot adequately 
represent the interests of constituents without also representing some 
of their own. As Senator Robert S. Kerr once said, "I represent the 
farmers of Oklahoma, although I have large farm interests. I represent 
the oil business in Oklahoma...and I am in the oil business...They don't
 want to send a man here who has no community of interest with them, 
because he wouldn't be worth a nickel to them."
 The problem is to distinguish special interests from the general 
interests of all constituents. Second, the "political interests" of 
legislatures include campaign contributions which they need to get 
elected, and which are generally not illegal and not the same as a 
bribe. But under many circumstances they can have the same effect. The 
problem here is how to keep the secondary interest in raising campaign 
funds from overwhelming what should be their primary interest—fulfilling
 the duties of office.
Politics in the United States is dominated in many ways by political campaign contributions.
 Candidates are often not considered "credible" unless they have a 
campaign budget far beyond what could reasonably be raised from citizens
 of ordinary means. The impact of this money can be found in many 
places, most notably in studies of how campaign contributions affect 
legislative behavior. For example, the price of sugar in the United 
States has been roughly double the international price for over half a 
century. In the 1980s, this added $3 billion to the annual budget of 
U.S. consumers, according to Stern, who provided the following summary of one part of how this happens:
| Contributions from the sugar lobby, 1983–1986 | Percent voting in 1985 against gradually reducing sugar subsidies | 
|---|---|
| > $5,000 | 100% | 
| $2,500–5,000 | 97% | 
| $1,000–2,500 | 68% | 
| $1–1,000 | 45% | 
| $0 | 20% | 
This $3 billion translates into $41 per household per year. This is in essence a tax
 collected by a nongovernmental agency: It is a cost imposed on 
consumers by governmental decisions, but never considered in any of the 
standard data on tax collections.
Stern notes that sugar interests contributed $2.6 million to 
political campaigns, representing well over $1,000 return for each $1 
contributed to political campaigns. This, however, does not include the 
cost of lobbying. Lessig cites six different studies that consider the 
cost of lobbying with campaign contributions on a variety of issues considered in Washington, D.C.
 These studies produced estimates of the anticipated return on each $1 
invested in lobbying and political campaigns that ranged from $6 to 
$220. Lessig notes that clients who pay tens of millions of dollars to 
lobbyists typically receive billions.
Lessig insists that this does not mean that any legislator has sold his or her vote.
 One of several possible explanations Lessig gives for this phenomenon 
is that the money helped elect candidates more supportive of the issues 
pushed by the big money spent on lobbying and political campaigns. He 
notes that if any money perverts democracy, it is the large 
contributions beyond the budgets of citizens of ordinary means; small 
contributions from common citizens have long been considered supporting 
of democracy.
When such large sums become virtually essential to a politician's
 future, it generates a substantive conflict of interest contributing to
 a fairly well documented distortion on the nation's priorities and 
policies.
Beyond this, governmental officials, whether elected or not, 
often leave public service to work for companies affected by legislation
 they helped enact or companies they used to regulate or companies 
affected by legislation they helped enact. This practice is called the "revolving door".
 Former legislators and regulators are accused of (a) using inside 
information for their new employers or (b) compromising laws and 
regulations in hopes of securing lucrative employment in the private 
sector. This possibility creates a conflict of interest for all public 
officials whose future may depend on the revolving door.
Finance industry and elected officials
Conflicts
 of interest among elected officials is part of the story behind the 
increase in the percent of US corporate domestic profits captured by the
 finance industry depicted in that accompanying figure.
Finance as a percent of US Domestic Corporate Profits
  Finance includes banks, securities and insurance. In 1932-1933, the 
total U.S. domestic corporate profit was negative. However, the 
financial sector made a profit in those years, which made its percentage
 negative, below 0 and off the scale in this plot.
From 1934 through 1985, the finance industry averaged 13.8% of U.S. 
domestic corporate profit. Between 1986 and 1999, it averaged 23.5%. 
From 2000 through 2010, it averaged 32.6%. Some of this increase is 
doubtless due to increased efficiency from banking consolidation and 
innovations in new financial products that benefit consumers. However, 
if most consumers had refused to accept financial products they did not 
understand, e.g., negative amortization loans, the finance industry would not have been as profitable as it has been, and the Late-2000s recession might have been avoided or postponed. Stiglitz argued that the Late-2000s recession
 was created in part because, "Bankers acted greedily because they had 
incentives and opportunities to do so". They did this in part by 
innovating to make consumer financial products like retail banking 
services and home mortgages as complicated as possible to make it easy 
for them to charge higher fees. Consumers who shop carefully for 
financial services typically find better options than the primary 
offerings of the major banks. However, few consumers think to do that. 
This explains part of this increase in financial industry profits. 
(Note, however, that Stiglitz has been accused of a conflict of 
interests and violation of Columbia University
 transparency policies for failing to disclose his status as a paid 
consultant to government of Argentina at the same time he was writing 
articles in defense of Argentina's planned default of over $1billion in 
bond debt during the 1998–2002 Argentine great depression,
 and for failing to disclose his paid consultancy to the government of 
Greece at the same time he was downplaying the risk of Greece defaulting
 on their debt during the Greek government-debt crisis of 2009.)
However, it is argued that a major portion of this increase and a driving force behind Late-2000s recession
 has been the corrosive effect of money in politics, giving legislators 
and the President of the U.S. a conflict of interest, because if they 
protect the public, they will offend the finance industry, which 
contributed $1.7 billion to political campaigns and spent $3.4 billion 
($5.1 billion total) on lobbying from 1998 to 2008.
To be conservative, suppose we
 attribute only the increase from 23.5% of 1986 through 1999 to the 
recent 32.6% average to governmental actions subject to conflicts of 
interest created by the $1.7 billion in campaign contributions. That's 
9% of the $3 trillion in profits claimed by the finance industry during 
that period or $270 billion. This represents a return of over $50 for 
each $1 invested in political campaigns and lobbying for that industry. 
(This $270 billion represents almost $1,000 for every man, woman and 
child in the United States.) There is hardly any place outside politics 
with such a high return on investment in such a short time.
Finance industry and economists
Economists
 (unlike other professions such as sociologists) do not formally 
subscribe to a professional ethical code. Close to 300 economists have 
signed a letter urging the American Economic Association (the discipline's foremost professional body), to adopt such a code. The signatories include George Akerlof, a Nobel laureate, and Christina Romer, who headed Barack Obama's Council of Economic Advisers.
This call for a code of ethics was supported by the public attention the documentary Inside Job (winner of an Academy Award) drew to the consulting relationships of several influential economists.
 This documentary focused on conflicts that may arise when economists 
publish results or provide public recommendation on topics that affect 
industries or companies with which they have financial links. Critics of
 the profession argue, for example, that it is no coincidence that 
financial economists, many of whom were engaged as consultants by Wall 
Street firms, were opposed to regulating the financial sector.
In response to criticism that the profession not only failed to predict the financial crisis of 2007–2008 but may actually have helped create it, the American Economic Association
 has adopted new rules in 2012: economists will have to disclose 
financial ties and other potential conflicts of interest in papers 
published in academic journals.
 Backers argue such disclosures will help restore faith in the 
profession by increasing transparency which will help in assessing 
economists' advice.
Stockbrokers
A conflict of interest is a manifestation of moral hazard,
 particularly when a financial institution provides multiple services 
and the potentially competing interests of those services may lead to a 
concealment of information or dissemination of misleading information. A
 conflict of interest exists when a party to a transaction could 
potentially make a gain from taking actions that are detrimental to the 
other party in the transaction.
There are many types of conflicts of interest such as a pump and dump
 by stockbrokers. This is when a stockbroker who owns a security 
artificially inflates the price by upgrading it or spreading rumors, and
 then sells the security and adds short position. They will then 
downgrade the security or spread negative rumors to push the price back 
down. This is an example of stock fraud. It is a conflict of interest 
because the stockbrokers are concealing and manipulating information to 
make it misleading for the buyers. The broker may claim to have the 
"inside" information about impending news and will urge buyers to buy 
the stock quickly. Investors will buy the stock, which creates a high 
demand and raises the prices. This rise in prices can entice more people
 to believe the hype and then buy shares as well. The stockbrokers will 
then sell their shares and stop promoting, the price will drop, and 
other investors are left holding stock that is worth nothing compared to
 what they paid for it. In this way, brokers use their knowledge and 
position to gain personally at the expense of others.
The Enron scandal
 is a major example of pump and dump. Executives participated in an 
elaborate scheme, falsely reporting profits, thus inflating its stock 
prices, and covered up the real numbers with questionable accounting; 29 executives sold overvalued stock for more than a billion dollars before the company went bankrupt.
Media
Any media
 organization has a conflict of interest in discussing anything that may
 impact its ability to communicate as it wants with its audience. Most 
media, when reporting a story which involves a parent company or a subsidiary,
 will explicitly report this fact as part of the story, in order to 
alert the audience that their reporting has the potential for bias due 
to the possibility of a conflict of interest.
The business model of commercial media organizations (i.e., any 
that accept advertising) is selling behavior change in their audience to
 advertisers. However, few in their audience are aware of the conflict of interest between the profit motive and the altruistic desire to serve the public and "give the audience what it wants".
Many major advertisers test their ads in various ways to measure the return on investment in advertising. Advertising rates are set as a function of the size and spending habits of the audience as measured by the Nielsen Ratings. Media action expressing this conflict of interest is evident in the reaction of Rupert Murdoch, Chairman of News Corporation, owner of Fox,
 to changes in data collection methodology adopted in 2004 by the 
Nielsen Company to more accurately measure viewing habits. The results 
corrected a previous overestimate of the market share of Fox. Murdoch 
reacted by getting leading politicians to denounce the Nielsen Ratings as racists. Susan Whiting,
 president and CEO of Nielsen Media Research, responded by quietly 
sharing Nielsen's data with her leading critics. The criticism 
disappeared, and Fox paid Nielsen's fees. Murdoch had a conflict of interest between the reality of his market and his finances.
Commercial media organizations lose money if they provide content
 that offends either their audience or their advertisers. The 
substantial media consolidation that occurred since the 1980s has 
reduced the alternatives available to the audience, thereby making it 
easier for the ever-larger companies in this increasingly oligopolistic
 industry to hide news and entertainment potentially offensive to 
advertisers without losing audience. If the media provide too much 
information on how congress spends its time, a major advertiser could be
 offended and could reduce their advertising expenditures with the 
offending media company; indeed, this is one of the ways the market 
system has determined which companies won and which either went out of 
business or were purchased by others in this media consolidation. 
(Advertisers don't like to feed the mouth that bites them, and often 
don't. Similarly, commercial media organizations are not eager to bite 
the hand that feeds them.) Advertisers have been known to fund media 
organizations with editorial policies they find offensive if that media 
outlet provides access to a sufficiently attractive audience segment 
they cannot efficiently reach otherwise.
Election years are a major boon to commercial broadcasters, 
because virtually all political advertising is purchased with minimal 
advance planning, paying therefore the highest rates. The commercial 
media have a conflict of interest in anything that could make it easier 
for candidates to get elected with less money.
Accompanying this trend in media consolidation has been a substantial reduction in investigative journalism,
 reflecting this conflict of interest between the business objectives of
 the commercial media and the public's need to know what government is 
doing in their name. This change has been tied to substantial changes in
 law and culture in the United States. To cite only one example, 
researchers have tied this decline in investigative journalism to an 
increased coverage of the "police blotter". This has further been tied to the fact that the United States has the highest incarceration rate in the world.
Beyond this, virtually all commercial media companies own 
substantial quantities of copyrighted material. This gives them an 
inherent conflict of interest in any public policy issue affecting 
copyrights. McChesney noted that the commercial media have lobbied 
successfully for changes in copyright law that have led "to higher 
prices and a shrinking of the marketplace of ideas", increasing the 
power and profits of the large media corporations at public expense. One
 result of this is that "the people cease to have a means of clarifying 
social priorities and organizing social reform".
 A free market has a mechanism for controlling abuses of power by media 
corporations: If their censorship becomes too egregious, they lose 
audience, which in turn reduces their advertising rates. However, the 
effectiveness of this mechanism has been substantially reduced over the 
past quarter century by "the changes in the concentration and 
integration of the media." Would the Anti-Counterfeiting Trade Agreement have advanced to the point of generating substantial protests
 without the secrecy behind which that agreement was negotiated—and 
would the government attempts to sustain that secrecy have been as 
successful if the commercial media had not been a primary beneficiary 
and had not had a conflict of interest in suppressing discussion 
thereof?
Mitigation
Removal
Sometimes, people who may be perceived to have a conflict of interest
 resign from a position or sell a shareholding in a venture, to 
eliminate the conflict of interest going forward. For example, Lord Evans of Weardale resigned as a non-executive director of the UK National Crime Agency after a tax-avoidance-related controversy about HSBC,
 where Lord Evans was also a non-executive director. This resignation 
was stated to have taken place in order to avoid the appearance of 
conflict of interest.
"Blind trust"
Blind trusts
 can perhaps mitigate conflicts of interest scenarios by giving an 
independent trustee control of a beneficiary's assets. The independent 
trustee must have the power to sell or transfer interests without 
knowledge of the beneficiary. Thus, the beneficiary becomes "blind" to 
the impact of official actions on private interests held in trust.
As an example, a politician who owns shares in a company that may
 be affected by government policy may put those shares in a blind trust 
with themselves or their family as the beneficiary. It is disputed 
whether this really removes the conflict of interest, however.
Blind trusts may in fact obscure conflicts of interest, and for 
this reason it is illegal to fund political parties in the UK via a 
blind trust if the identity of the real donor is concealed.
Disclosure
Commonly,
 politicians and high-ranking government officials are required to 
disclose financial information—assets such as stock, debts such as loans, and/or corporate positions held, typically annually.
 To protect privacy (to some extent), financial figures are often 
disclosed in ranges such as "$100,000 to $500,000" and "over 
$2,000,000". Certain professionals are required either by rules related 
to their professional organization, or by statute,
 to disclose any actual or potential conflicts of interest. In some 
instances, the failure to provide full disclosure is a crime.
However, there is limited evidence regarding the effect of conflict of interest disclosure despite its widespread acceptance. A 2012 study published in the Journal of the American Medical Association
 showed that routine disclosure of conflicts of interest by American 
medical school educators to pre-clinical medical students were 
associated with an increased desire among students for limitations in 
some industry relationships.
 However, there were no changes in the perceptions of students about the
 value of disclosure, the influence of industry relationships on 
educational content, or the instruction by faculty with relevant 
conflicts of interest.
And, an increasing line of research suggests that disclosure can 
have "perverse effects" or, at least, is not the panacea regulators 
often take it to be.
Recusal
Those with a conflict of interest are expected to recuse
 themselves from (i.e., abstain from) decisions where such a conflict 
exists. The imperative for recusal varies depending upon the 
circumstance and profession, either as common sense ethics, codified 
ethics, or by statute.
 For example, if the governing board of a government agency is 
considering hiring a consulting firm for some task, and one firm being 
considered has, as a partner, a close relative of one of the board's 
members, then that board member should not vote on which firm is to be 
selected. In fact, to minimize any conflict, the board member should not
 participate in any way in the decision, including discussions.
Judges
 are supposed to recuse themselves from cases when personal conflicts of
 interest may arise. For example, if a judge has participated in a case 
previously in some other judicial role he/she is not allowed to try that
 case. Recusal is also expected when one of the lawyers in a case might 
be a close personal friend, or when the outcome of the case might affect
 the judge directly, such as whether a car maker is obliged to recall a 
model that a judge drives. This is required by law under Continental civil law systems and by the Rome Statute, organic law of the International Criminal Court.
Third-party evaluations
Consider a situation where the owner of a majority of a public 
companies decides to buy out the minority shareholders and take the 
corporation private. What is a fair price? Obviously it is improper 
(and, typically, illegal) for the majority owner to simply state a price
 and then have the (majority-controlled) board of directors
 approve that price. What is typically done is to hire an independent 
firm (a third party), well-qualified to evaluate such matters, to 
calculate a "fair price", which is then voted on by the minority 
shareholders.
Third-party evaluations may also be used as proof that transactions were, in fact, fair ("arm's-length"). For example, a corporation that leases an office building that is owned by the CEO
 might get an independent evaluation showing what the market rate is for
 such leases in the locale, to address the conflict of interest that 
exists between the fiduciary
 duty of the CEO (to the stockholders, by getting the lowest rent 
possible) and the personal interest of that CEO (to maximize the income 
that the CEO gets from owning that office building by getting the 
highest rent possible).
A January 2018 report by the Public Citizen
 non-profit describes dozens of foreign governments, special interest 
groups and GOP congressional campaign committees that spent hundreds of 
thousands of dollars at President Donald Trump's
 properties during his first year in office. The study said that these 
groups clearly intended to win over the president by helping his 
commercial business empire profit while he held the office.
