optimal duplication of effort in advocacy systems abstract the paper focuses on the creation of information for decision making when agents effort is non observable and rewards are indirect that is only based on the final decision following dewatripont and tirole dewatripont m tirole j 1999 advocates journal of political economy 107 1 39 the paper shows that the creation of advocates of special interests as opposed to non partisans generates an efficient mechanism of mutual monitoring that reduces the scope for manipulation such monitoring is preferable over imposing penalties for detected manipulation it is also preferable to creating an agency that monitors the non partisan agent applications to transfer price policies and comparative judicial systems are considered

effects of cost changes on oligopolists profits this paper considers cost changes affecting all firms in a constantreturns to scale cournot oligopoly cost increases may paradoxically benefit some or even all firms whether a firm benefits or is harmed depends only on whether its market share exceeds a threshold level s on whether industry costs increase or decrease on the number of firms and on the elasticity of the demand curve s slope or equivalently the fraction of cost changes that are passed on conditions where industry structure alone determines the effect of cost changes on firms profits and conditions where cost increases necessarily harm some firms are developed this paper considers the effects of a change in cost on outputs and profits in an industry composed of firms with constant returns to scale these effects are easy to see in the extreme cases of monopoly and perfect competition but

informational asymmetries strategic behavior and industrial organization one of the most active and exciting areas of economic research over the last several years has been the use of noncooperative games of incomplete information to model industrial competition this work has yielded not only a remarkable number of papers but also several new insights on and explanations of fundamentally important issues the purpose of this paper is to attempt an appreciation and evaluation of this work because most of our individual and joint work since about 1979 has been in this mode it will come as no surprise that we are proponents of this line of research however there are several questions and potential problems that we see as arising in connection with this methodology and we will attempt to address these first a disclaimer we are not attempting a survey of the applications of asymmetric information games aig to industrial organization although we will refer in a highly selective fashion to a number of prominent strands in this literature in particular where any references are provided at all they are typically only to the earliest contributions to a subject even more we do not deal with work in which informational asymmetries are important but the analysis is not game theoretic for example search and price dispersion or the early work on the lemons problem and on moral hazard and adverse selection in insurance markets or with game theoretic treatments that assume complete information i aig methods and applications

the market for quacks a group of n quacks plays a price competition game facing a continuum of patients who recover with probability whether or not they acquire a quack s treatment if patients chose rationally the market would be inactive i assume however that patients choose according to a boundedly rational procedure which re ects anecdotal reasoning this element of bounded rationality has signi cant

material interests moral reputation and crowding out species protection on private land we consider how the reputation of being socially responsible works as an effective source of motivation in protecting a public good such as endangered species this paper investigates the mechanism design for endangered species protection on private land under asymmetric information about reputation and land quality we examine optimal monetary transfer by designing an efficient mechanism which takes into account the crowding out effect of monetary rewards on socially responsible behavior we find landowners who have good reputation contribute more than the optimum level landowners with poor reputation sacrifices information rent rather they buy reputation

unawareness and selective disclosure the effect of school quality information on property prices the australian government launched the my school website in 2010 to provide standardised information about the quality of schools to the australian public this paper combines data from this website with home sales data for the state of victoria to estimate the effect of the publication of school quality information on property prices we use a difference in difference approach to estimate the causal effect of the release of information about high quality and low quality schools relative to medium quality schools in the neighborhood and find that the release of information about high quality schools increases property prices by 3 6 percent whereas the release of information about low quality schools has no significant effect the findings indicate that many buyers are unaware of the relevance of school quality information and that real estate agents pursue a strategy of disclosing information about high quality schools to increase the sales price results from a survey of victorian real estate agents provide evidence in favor of this strategy

the efficiency of equity in organizational decision processes it is now widely accepted that rent seeking anne krueger 1974 or directly unproductive profit seeking jagdish bhagwati 1982 may cause inefficiencies in the context of public sector decisions the possibility that government decisions for example about taxes quotas franchises or standards may create or redistribute rents induces private parties to spend valuable resources to influence that distribution even when such expenditures carry no social benefit moreover the social cost of rent seeking can exceed the value of the resources spent trying to gain and protect rents for example because the fear of losing wealth through redistribution reduces the incentives for wealth creation treating rent seeking activities as characteristic of public sector decision processes ignores the fact that similar phenomena are to be found in firms unions and other private sector organizations our recent work milgrom 1988 our 1988 1990 papers attempts to identify the advantages of decision processes private or public that permit rent seeking and to incorporate these into a cost benefit analysis of optimal decision processes our work begins with an analysis of why rents and quasi rents arise in organizations and of the forms that the rent seeking they engender may take some measures to insulate the decision process from rent seeking such as limits on the provision of information by interested parties or restrictions on the range of options considered may degrade the quality of decisions especially by blocking the flow of valuable information optimal decision processes balance the costs of rent seeking against the value of information obtained several aspects of the rules affect the opportunities that members have to spend resources trying to alter the distribution of rents to ascertain the possibilities for rent seeking the analyst must ask questions like can the parties propose new initiatives at any time can they give volumes of testimony in a form of their own choosing can they appeal adverse decisions are decision makers obliged to respond to the parties initiatives is the range of actions that they can take in response relatively broad rather than being tightly constrained by property rights or other formal rules more affirmative answers to these questions lead to more opportunities or greater incentives for costly rent seeking as a kind of shorthand we call decision processes that have more of these elements more open processes the very elements that make a process open to rent seeking may also add flexibility and responsiveness helping to ensure that important ideas and proposals are fully considered from this perspective the benefits of openness can in principle be measured by a value of information calculation in the usual manner of statistical decision theory weighing the costs and benefits it follows that a more open process is more desirable when the rents available for redistribution are low and the value of the information that might be acquired is high conversely when the potential for redistribution is high and the value of information is low the optimal decision process is less open this kind of reasoning helps to illuminate the variations in the decision processes that are found in many organizations we have discussed a number of examples in our earlier work including the characteristics of personnel departments the contrasting patterns of decision making employment and compensation in u s and japanese firms professor of economics stanford university and jonathan b lovelace professor of economics graduate school of business stanford university stanford ca 94305 respectively this work was supported by the national science foundation

the effects of prior beliefs and learning on consumers acceptance of genetically modified foods abstract new food products using genetically modified crops appeared in u s supermarkets starting in 1996 and consumers perceived some risks this paper examines the role of consumers prior beliefs about genetic modification and of diverse new information on their willingness to pay for foods that might be genetically modified we use data from economics experiments and show that participants who had informed prior beliefs discounted gm labeled food products more highly than those who had uninformed prior beliefs uninformed participants were especially susceptible to information from interested and third parties in contrast informed participants were generally not affected significantly by new information

the market for lawyers and quality layers in legal services we study the functioning of the market for lawyers considering the strategic interaction among litigants lawyers and judges we investigate the value of legal representation and of systems of quality certification such as the queen s counsel system in our setting higher quality lawyers obtain better quality evidence and are better able to interpret it judges receive information from the lawyers and have reputational concerns we show that reputational concerns generate a decision bias in favor of certified lawyers and that this causes misallocation of lawyers at the market equilibrium as a result whereas a higher quality of lawyers increases welfare public information over quality may be welfare reducing

contracting in strategic situations abstract cooperative games are distinguished from noncooperative games by the ability to form binding pre play agreements the notion of a binding agreement however is ambiguous for two reasons first contracts can be enforced by various provisions for the payment of damages in the event of breach second contracts generally are incomplete not specifying unique actions for each possible state of the world this paper examines the interaction between incompletely specified and enforced pre play contracts and the outcomes that are achieved in 2 player strategic situations comparisons are made among various damage measures for breach of contract

information revelation in auctions with common and private values we explore the incentives to reveal verifiable private information when there are both common and private components to agents valuations and when private information is held in both dimensions when agents observe only one signal they have no incentive to reveal the signal because such a revelation would negate their information advantage however when agents observe multiple signals they may be incentivized to reveal certain signals that could lower their opponents bids and thereby result in a higher profit from other signals this paper shows that there exists an equilibrium with revelation of common value signals in standard auctions which is an efficient equilibrium that maximizes the social welfare and could provide the seller with a higher profit than a situation with no information revelation

the war of information we analyse political contests campaigns between two parties with opposing interests parties provide costly information to voters who choose a policy the information flow is continuous and stops when both parties quit parties actions are strategic substitutes increasing one party s cost makes that party provide more and its opponent provide less information for voters parties actions are complements and hence raising the advantaged party s cost may be beneficial asymmetric information adds a signalling component resulting in a belief threshold at which the informed party s decision to continue campaigning offsets other unfavourable information

an economic approach to influence activities in organizations members of organizations spend considerable time effort and ingenuity attempting to influence decision makers such influence activities may bring benefits to the organization but they also involve real costs this essay offers an economic rationale for such influence activity as representing rational self interested behavior in the presence of informational asymmetries and an analysis of how the design of the organization s structure and policies should respond to the incentives for attempting influence it is posited that information valuable for the organization s decision making is directly available only to members of the organization who have some personal stake in the decisions these individuals may then have an incentive to try to manipulate the information they develop and provide in order to influence the resulting decisions to their benefits this can be costly both in degrading the quality of decision making and in diverting the attention and effort of the organization s members from more productive activities the organization has three different methods it can employ to discourage excessive influence activities and to encourage more directly productive uses of time and effort it can limit access to decision makers and participation in decision making it can alter its decision making criteria to favor those performing well in productive activities and it can provide direct financial incentives to encourage the desired allocation of effort it is shown that an efficiently designed organization will use such financial incentives only as a last resort instead it will always first alter its decision participation policies and decisionmaking criteria

effects and value of verifiable information in a controversial market evidence from lab auctions of genetically modified food food products containing genetically modified gm ingredients have entered the market over the past decade the biotech industry and environmental groups have disseminated conflicting private information about gm foods this paper develops a unique methodology for valuing independent third party information in such a setting and applies this method to consumers willingness to pay for food products that might be gm data are collected from real consumers in an auction market setting with randomized information and labeling treatments the average value of third party information per lab participant is small but the public good value across u s consumers is shown to be quite large jel c91 d12 d82

the price of advice we develop a model of consulting advising where the role of the consultant is to reveal signals to her client that refine the client s original private estimate of the profitability of a project although the client can perfectly observe and evaluate these signals the consultant may only be able to do the same imperfectly or not at all this captures the idea that the expert may not fully understand the impact of her advice on the client we characterize the optimal contract between the consultant and her client it is a menu consisting of pairs of transfers specifying payments between the two parties in case the project is undertaken by the client and in case it is not the main result of the article is that in the optimal mechanism the consultant obtains the same profit as though she could perfectly observe and evaluate the impact of the signals whose release she controls on the client s profit estimate

who do consumers trust for information the case of genetically modified foods to be effective groups that disseminate information need the trust of consumers when multiple groups provide conflicting information on a new product or process like gm foods consumers place different levels of trust in the various sources we present a model of the contributions of personal and social capital of a consumer and test a multinominal logit model of relative trust in five different sources of information on genetic modification using a unique data set among our findings is that an increase in consumer s education lowers the probability of trusting information from government private industry organizations consumer and environmental groups or other sources relative to information from an independent third party source and conservative religious affiliation reduces the odds of a consumer trusting private industry organization and increases the odds of trusting nobody relative to an independent third party source

trade association disclosure rules incentives to share information and welfare in this article i propose a monopolistic competition framework to analyze the effects of different disclosure rules used by trade associations on the incentives to share information and on the welfare of consumers firms and society this framework is appropriate whenever a single firm cannot influence aggregate market magnitudes and serves as a benchmark for the analysis of information pooling agreements abstracting from strategic considerations i report two main results first a policy of nonexclusionary disclosure destroys the incentives to share information while exclusionary disclosure preserves them second information sharing increases expected total surplus with cournot competition but decreases it with bertrand competition in the context of a quadratic normal model with demand uncertainty

information provision by interest groups we investigate interest groups incentives to inform consumers about the damaging practices of firms and the impact such an ig has on firms technology choices the ig aims to reduce the production of some bad say pollution it can at a cost investigate firms production practices and inform consumers about its findings since consumers care about the environment revealing differences in pollution levels between firms leads to vertical product differentiation the information by shifting sales from dirty towards clean firms reduces pollution we show that the ig is most inclined to investigate firms in relatively competitive industries and that the threat of being unmasked as a polluter prompts dirty firms to adopt a clean technology

the effect of newspaper entry and exit on electoral politics we use new data on entries and exits of us daily newspapers from 1869 to 2004 to estimate effects on political participation party vote shares and electoral competitiveness our identification strategy exploits the precise timing of these events and allows for the possibility of confounding trends we find that newspapers have a robust positive effect on political participation with one additional newspaper increasing both presidential and congressional turnout by approximately 0 3 percentage points newspaper competition is not a key driver of turnout our effect is driven mainly by the first newspaper in a market and the effect of a second or third paper is significantly smaller the effect on presidential turnout diminishes after the introduction of radio and television while the estimated effect on congressional turnout remains similar up to recent years we find no evidence that partisan newspapers affect party vote shares with confidence intervals that rule out even moderate sized effects we find no clear evidence that newspapers systematically help or hurt incumbents

strategic information revelation we analyze the problem in which agents have non public information and are to play an asymmetric information game the agents may reveal some or all of their information to other agents prior to playing this game revelation is via exogenously specified certifiable statements the equilibria resulting from various revelation strategies are used to determine equilibrium revelation of information sufficient conditions are provided for complete revelation of all private information a number of examples are provided illustrating when revelation will or will not occur in commonly analyzed games many economic problems are characterized by the presence of both strategic behaviour on the part of individuals and by asymmetric information models encompassing both of these characteristics have been used successfully to examine questions in many fields usually using the concept of bayesian nash equilibrium as the solution concept typically the agents information is given exogenously and is fixed throughout the analysis modelling the information structure as static is appropriate for some problems but not for all in particular situations that are inherently dynamic most economic encounters allow for some interchange between the agents before the outcome is settled irrevocably in such circumstances it is possible that at least one or more of the agents possessing non public information may be able to reveal part or all of his information to one or all of the other agents in the economy during the course of their contact to the extent that such a communication is believed by the other agents the priors of the other agents will change and we will have what is in essence a new asymmetric information game new in

opinions as incentives we study costs and benefits of differences of opinion between an adviser and a decision maker even when they share the same underlying preferences over decisions a difference of opinion about payoff relevant information leads to strategic information acquisition and transmission a decision maker faces a fundamental trade off a greater difference of opinion increases an adviser s incentives to acquire information but exacerbates the strategic disclosure of any information that is acquired nevertheless when choosing from a rich pool of opinion types it is optimal for a decision maker to select an adviser with some difference of opinion centralization of authority is essential to harness these incentive gains since delegation to the adviser can discourage effort

assessing the contribution to innovation of private equity investors a study on european buyouts abstract the paper provides an empirical analysis of the patenting activity of a sample of western european manufacturing firms undergoing a buyout between 1998 and 2004 a panel data design is used to test whether the characteristics of the deal and of private equity pe firms can affect acquired companies subsequent innovation effort as measured by the number of patents granted by the epo results support the view that the innovation activity of portfolio firms is affected by different types of investors pursuing different objectives and differing in their risk propensity expected returns and investment policies the characteristics of lead investors size stage specialization geographical location and of the deal amount invested presence of multiple investors are also investigated and are found to differently affect the post buyout innovation activity of sample firms

the economics of breakdowns checkups and cures a market in which the owner of a durable good x contracts with an expert for diagnostic and treatment services is studied good x may be in one of three states health disease or failure only experts can determine whether x is healthy or diseased and perform treatment the owner cannot tell whether recommended treatment is really needed this creates an information based demand for health insurance by risk neutral consumers imperfections in the market for spot insurance may give rise to free diagnostic checks strategic procrastination and long term health maintenance agreements

a simple model of the commercial lobbying industry in this paper we present a model of the behavior of commercial lobbying firms such as the so called k street lobbyists of washington d c in contrast to classical special interest groups commercial lobbying firms represent a variety of clients and are not directly affected by policy outcomes they are hired by citizens or groups of citizens to advocate on their behalf to policymakers in our analysis we address two basic questions why do commercial lobbying firms exist and what are the implications of their existence for social welfare we answer the first part of this question by proposing that commercial lobbying firms possess a verification technology that allows them to improve the quality of information concerning the social desirability of policy proposals this gives policymakers the incentive to allocate their scarce time to lobbying firms essentially it is this access to policymakers that lobbying firms sell to their clients to address the question of social welfare we construct a simple general equilibrium model that includes commercial lobbying firms and compare the equilibrium obtained under market provision of lobbying services to the first best optimum we find that the market level of lobbying services can be socially either too large or too small and characterize when each will be the case

sales talk cancellation terms and the role of consumer protection this paper analyses contract cancellation and product return policies in mar kets in which sellers advise customers about the suitability of their oering when customers are fully rational it is optimal for sellers to oer the right to cancel or return on favorable terms a generous return policy makes the seller s cheap talk at the point of sale credible this observation provides a possible explanation for the excess refund puzzle and also has implications for the management of customer reviews when customers are credulous instead sellers have an incentive to set unfavorable terms to exploit the in ated beliefs they induce in their customers the imposition of a minimum statutory standard even if it is not binding can improve welfare and consumer surplus when at least some customers are credulous in con trast competition policy reduces contractual ine ciencies with rational customers but it is not eective with credulous customers

communication costs information acquisition and voting decisions in proxy contests this article synthesizes some recent progress in the theories of corporate control and political lobbying to model the proxy campaign as a political campaign the model yields a number of testable implications only some of which have been examined in the literature for example if the loss from voting for a bad dissident exceeds the gain from voting for a good dissident the model predicts that as communication costs fall the number of proxy fights increases announcement day returns decrease and the fraction of dissident wins first increases and then decreases article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

discriminatory information disclosure we consider a price discrimination problem in which a seller has a single object for sale to a potential buyer at the time of contracting the buyer s private type is his incomplete private information about his value and the seller can disclose additional private information to the buyer we study the question of whether discriminatory information disclosure can be protable to the seller under the assumption that for the same disclosure policy the amount of additional private information that the buyer can learn depends on his private type we establish sucient conditions under which it is prot maximizing for the seller to grant each private type of the buyer full access to all additional private information under her control in general however discriminatory disclosure can be optimal because it reduces the information rent accrued to private types of the buyer without much impact on the trade surplus

information sharing and oligopoly in agricultural markets the role of the cooperative bargaining association we study incentives for information sharing among agricultural intermediaries in imperfectly competitive markets for farm output information sharing always increases expected grower and total surplus but may reduce expected intermediary profits even when expected profits increase with information sharing intermediary firms face a prisoner s dilemma where it is privately rational to withhold information given that other firms report truthfully this equilibrium can be avoided if firms information reports are verifiable and if firms commit to an ex ante contract that enforces participation in information sharing we show how agricultural bargaining legislation can implement such a contract with the bargained farm price representing a sufficient statistic of all information held by intermediary firms

what the seller won t tell you persuasion and disclosure in markets imagine that you are considering an investment in a new public offering of a firm s shares the firm s officers make a presentation that includes an audited financial statement an earnings forecast reviewed by its prestigious investment bankers and an impressive demonstration of its new technology or suppose that you are buying a new furnace to replace an old one that is not working well the salesman displays a chart showing that the projected total life cycle cost of one particular model including capital costs and fuel usage over the projected lifetime of the furnace is lower than that of some competing models you have considered this paper reviews the theoretical arguments about how sellers disclose information in an attempt to encourage buyers and the potential role for regulation in encouraging efficient disclosure of information how well does a system of private reporting work when should we expect all the relevant information to be reported if testing and reporting by the seller are costly will too little testing and reporting be done or too much when some information is withheld what sort of information is withheld how do rational buyers respond to such withholding how are prices and welfare affected what role is there for laws and regulations to improve the functioning of markets we address these questions by studying the theory of persuasion games games in which one or more sellers provide verifiable information to buyers to influence the actions they take

the advertising mix for a search good we extend the persuasion game to bring it squarely into the economics of advertising we model advertising as exciting consumer interest into learning more about the product and determine a firm s equilibrium choice of advertising content over quality information price information and horizontal match information equilibrium is unique whenever advertising is necessary the outcome is a separating equilibrium with quality unravelling lower quality firms need to provide more information for a given quality level as a function of consumer visit costs first quality information is disclosed then price information and then horizontal product information are added to the advertising mix some suggestive evidence is provided from airline ads in newspapers this paper was accepted by j miguel villas boas marketing

control premiums minority discounts and optimal judicial valuation abstract this article characterizes controlling and minority share prices and optimal appraisal remedy valuation rules in a rational expectations equilibrium the model identifies a set of optimal judicial valuation policies that would motivate shareholders to make optimal investment and freeze out choices and identifies consequences of judicial valuation error the model suggests that the share appraisal rule under which minority shares are assessed a minority discount in freeze out appraisals would be more optimal than delaware s pro rata doctrine which forbids discounting of minority shares in accordance with the share appraisal rule and in contradiction with their own pro rata doctrine delaware courts frequently allow implicit discounts to minority shares in freeze out appraisals in summary the model articulates why courts should not equate minority share value with market price consistent with this implication delaware courts have always uniformly rejected the notion that market price should

a theory of quits and layoffs with efficient turnover this paper answers the efficient turnover literature s long silence regarding the quit layoff distinction treating quits as worker initiated separations and layoffs as firm initiated separations i establish that the existence of layoffs is compatible with optimizing workers and firms forming and dissolving employment matches to exploit all the gains from trade the efficient turnover approach is shown to be consistent with many empirical regularities that distinguish quits from layoffs structural implications of the model are tested on data from the psid

auctions with endogenous quantity this article studies auctions in which several sellers compete for the right to sell to a market characterized by a negatively sloped demand curve in this environment the quantity traded becomes endogenous this effect leads to three results concerning the outcomes of open versus first price sealed bid auctions first an open auction yields a higher expected price than does sealed bidding second and more important the open auction captures less of the potential gains from trade than does the sealed bid auction third for broad classes of demand curves the efficiency gains from switching to sealed bids from an open auction accrue to both sellers and the buyer so that all concerned parties would agree to the change a direct application of the theory is to procurement the heavy use of sealed bidding in procurement is seen as rational in light of these results auction models with endogenous quantity could be an alternative to price setting oligopoly models for the study of price formation in general for the latter impose strong information requirements on agents and yield only equilibrium price vectors not equilibrium processes for determining prices

competition economics and antitrust in europe this paper aims to assess the influence that economic analysis has had on competition policy in the european union over the last twenty years economists are increasingly used in antitrust cases the annual turnover of the main economic consultancy firms has increased by a factor of 20 since the early 1990s and currently exceeds 20 million this is about 15 of the aggregate fees earned on antitrust cases a proportion close to that in the us the economic resources mobilized by the eu commission are however an order of magnitude smaller and this imbalance is a source of concern the legal framework and the case decisions have also been influenced by economic analysis in important ways for instance the analysis of agreements between firms has increasingly focused on effects the analysis of the factors that determine effective competition has become more sophisticated the concept of collective dominance has been progressively developed in terms of the theory of collusion in repeated interactions and quantitative methods have become more important however enforcement has sometimes appealed to economic reasoning in flawed or speculative ways the paper discusses procedural reasons why this may have occurred this paper assesses the system of evidence gathering implemented by the commission in the light of the law and economics literature it is concluded that while the reforms recently implemented by the commission do address the main weaknesses of this system they may still not allow for the most effective development of economic theory and evidence in actual cases damien j neven

public protests and policy making technological advances and the development of social media have made petitions public protests and other form of spontaneous activism increasingly common tools for individuals to influence decision makers to study these phenomena in this article i present a theory of petitions and public protests that explores their limits as mechanisms to aggregate information the key assumption is that valuable information is dispersed among citizens through petitions and protests citizens can signal their private information to the policy maker who can then choose to use it or not i first show that if citizens individual signals are not sufficiently precise information aggregation is impossible no matter how large is the population of informed citizens even if the conflict with the policy maker is small i then characterize the conditions on conflict and the signal structure that guarantee information aggregation when these conditions are satisfied i show that full information aggregation is possible as the population grows to infinity when they are not satisfied i show that information aggregation may still be possible if social media are available

manipulated news model electoral competition and mass media abstract this paper investigates the relationship between media manipulation the strategic suppression of relevant information by mass media and self mediatization the strategic exploitation of media coverage by candidates in elections in the model a voter cannot directly observe the policies proposed by two office motivated candidates the voter learns this information through media reports before voting takes place while the media outlet suppresses some of this information because the voter s decision making could be incorrect direct distortion the candidates have an incentive to win the election by influencing the media coverage through policy settings indirect distortion as a result policy convergence to the voter s ideal policy occurs if and only if the media bias is sufficiently small we then characterize the set of equilibria in terms of the degree of distortion the results suggest that if either strategic media manipulation or competition among the candidates is omitted then the distortion is nonnegligibly misspecified

are voters cursed when politicians conceal policy preferences in campaigns candidates often avoid taking positions on issues concealing the policy preferences that would guide them if elected this paper describes a novel explanation for ambiguity in political campaigns it develops a model of candidate competition in which policy motivated candidates can choose whether or not to announce their policy preferences to voters it applies eyster and rabin s econometrica 73 5 1623 1672 2005 concept of cursed equilibrium which allows for varying degrees of understanding of the connection between type policy preference and strategy whether to announce if voters updated according to bayes rule they would understand that candidates who do not announce positions are strategically concealing an unpopular policy preference in equilibrium only the most extreme candidates those located furthest from the median voter s position would choose to take no position however if voters do not sufficiently appreciate the informational content of a non announcement unraveling will not occur and both extremists and more moderate candidates will not announce positions

domestic opposition and signaling in international crises this article explores the effect of domestic political competition on the escalation of international crises it combines an incomplete information model of crisis bargaining with a simple model of two party electoral choice one state has two strategic actors a government and an opposition party both of which declare openly whether they support the use of force to alter the status quo the rival state updates its beliefs and selects its strategy in response to both signals the parties payoffs depend upon a retrospective evaluation by the domestic electorate the model shows that the inclusion of a strategic opposition party decreases the ex ante probability of war by helping to reveal information about the state s preferences this finding has important implications for research on democracy and international conflict since it suggests a mechanism through which democratic states can overcome informational asymmetries which have been identified as a central obstacle to negotiation

optimal disclosure decisions when there are penalties for nondisclosure we study a seller of an asset who is liable for damages if the seller fails to disclose to buyers an estimate of the asset s value he knew prior to the sale our results include as either the damages multiplier that determines the size of the damages the seller must pay buyers increases or as the probability the seller is caught withholding his estimate from buyers increases the seller discloses his estimate less often and as the precision of the seller s estimate increases he sells a larger fraction of the asset

duopoly information exchange the case of unknown slope abstract we model information exchange between duopolists facing a common random demand the slope of the common demand curve facing the firms is assumed unknown and firms observe private signals about this slope we show that for sufficiently large variation in the demand slope firms earn strictly higher profit when they share their information rather than keeping it private even with constant marginal costs and homogeneous goods in this case it is a nash equilibrium for the duopolists to share their information in a quid pro quo information exchange consistent with earlier models information exchange raises welfare

effects of carbon reduction labels evidence from scanner data we investigate the effects of carbon reduction labels using a detailed scanner data set using a difference in differences estimation strategy we find that having a carbon label has no impact on detergent prices or demand we also investigate possible heterogeneous effects of carbon labels using the synthetic control method we find no evidence to indicate that the prices for the counterfactual detergents without the label would have been any different from the prices of the carbon labeled detergents we investigate the reasons for these results and conclude that the specific design of the carbon label is responsible for its lack of success jel d12 d83 l15 q54

how individual preferences are aggregated in groups an experimental study abstract this paper experimentally investigates how individual preferences through unrestricted deliberation are aggregated into a group decision in two contexts reciprocating gifts and choosing between lotteries in both contexts we find that median group members have a significant impact on the group decision but the median is not the only influential group member non median members closer to the median tend to have more influence than other members by investigating the same individual s influence in different groups we find evidence for relative position in the group having a direct effect on influence these results are consistent with predictions from spatial models of dynamic bargaining for members with intermediate levels of patience we also find that group deliberation involves bargaining and compromise as well as persuasion preferences tend to shift towards the choice of the individual s previous group especially for those with extreme individual preferences

media as watchdogs the role of news media in electoral competition abstract we develop an equilibrium model to analyze the role of the media in electoral competition when policy payoffs are state dependent party policies do not converge to the median voter s ideal policy if the media report only party policies news analysis about the state though possibly biased can discipline off equilibrium deviations and make the parties adopt more centrist policies since voters are rational the party favored by the media need not win with a higher probability instead media bias may reduce the effectiveness of electoral competition and lead to more polarized policies

conflicts and common interests in committees committees improve decisions by pooling members independent information but promote manipulation obfuscation and exaggeration of private information when members have conflicting preferences committee decision procedures transform continuous data into ordered ranks through voting this coarsens the transmission of information but controls strategic manipulations and allows some degree of information sharing each member becomes more cautious in casting the crucial vote than when he alone makes the decision based on own information increased quality of one member s information results in his casting the crucial vote more often committees make better decisions for members than does delegation

costly participation and heterogeneous preferences in informational committees informational committees are groups of people who are designated to gather information this article develops a simple model of committee size based on costly participation and preference heterogeneity in a setting in which the information structure and policy preferences are both represented by normal random variables i characterize an equilibrium under the mean decision rule and derive the optimal committee size i show that when effort costs are sufficiently high preference heterogeneity can provide members additional incentives to gather information and thus the optimal committee size and the principal s expected payoff can increase in the heterogeneity of committee members policy preferences

the roles of reputation and transparency on the behavior of biased experts we analyze situations in which an expert is biased toward some decision but cares also about his reputation in the market for experts the information the expert reveals decreases as his bias moves toward stronger preference for the status quo we show that it is optimal to publicly disclose both the expert s contribution and his identity surprisingly revealing the intensity of the expert s bias doesn t always improve the information he reveals in equilibrium the presence of a second expert raises the first expert s incentives to report truthfully when reports are public but reduces them when they are secret in particular having an option to call another expert may be detrimental in terms of information production if reports are not public finally sequential consultation of experts reduces the information obtained when reports are public but raises it when they are secret

does conflict of interest lead to biased coverage evidence from movie reviews media outlets are increasingly owned by conglomerates inducing a conflict of interest a media outlet can bias its coverage to benefit companies in the same group we test for bias by examining movie reviews in media outlets owned by news corp such as the wall street journal and time warner such as time we find higher ratings for 20th century fox movies in news corp outlets compared to movies by other studios to disentangle bias from correlation of taste we introduce and validate a novel matching procedure using individual movie ratings from online platforms using this procedure we find no evidence of bias in news corp nor time warner outlets we reject even small effects such as bias of one extra star out of four every thirteen movies we test for differential bias when the return to bias is plausibly higher examine bias by media outlet and by journalist as well as editorial bias we also consider bias by omission whether media outlets are more likely to review highly rated movies by affiliated studios and conflict of interest within a movie aggregator in none of these dimensions do we find evidence of bias we relate to previous work and discuss three explanations for the lack of bias in our setting high values of media reputation organizational features in a conglomerate and low returns to bias

when does a firm disclose product information a firm chooses a price and the product information it discloses to a consumer whose tastes are privately known we provide a necessary and sufficient condition on the match function for full disclosure to be the unique equilibrium outcome whatever the costs and prior beliefs about product and consumer types it allows for products with different qualities as well as some horizontal match heterogeneity with independently distributed product and consumer types full disclosure is always an equilibrium and a necessary and sufficient equilibrium condition is that all firm types earn at least the full disclosure profit

exposing false advertising countries rely on different public and private agents to enforce consumer protection and fair competition regulations to analyze the repercussions of different regimes on social welfare we consider the possibility of false advertising by a firm in an environment with duopolistic competition and with consumers who can be rational or naive regarding the trustworthiness of advertising claims we compare the incentives for and outcomes of false advertisement verification and injunction requests made by one of three parties a government agency with a broad focus maximizing ex post total welfare and two narrowly focused parties the first a public or private party focused on consumer welfare net of its own enforcement costs and the second a competitor interested exclusively in its own profits considering ex ante welfare we find that having a narrowly focused party as the plaintiff can be optimal due to government agency commitment problems the optimal regime depends on both the share of the population s naive consumers and the level of enforcement costs resume denonciation de la publicite mensongere pour veiller a l application des reglementations en matieres de protection des consommateurs et de concurrence loyale les etats s appuient sur differents regimes de controle representes par des agents publics et prives afin d analyser les repercussions de ces differents regimes sur le bien etre nous evaluons la possibilite qu une entreprise puisse diffuser de la publicite mensongere dans un environnement concurrentiel duopolistique avec des consommateurs potentiellement rationnels ou naifs relativement a la veracite des allegations publicitaires nous comparons les mesures incitatives pour controler la publicite mensongere et leurs resultats ainsi que les mises en demeure initiees par l une de ces trois parties une agence gouvernementale a visee large aux fins de maximisation totale du bien etre ex post et deux autres parties a visee plus ciblee l une publique ou privee tournee vers le bien etre des consommateurs deduction faite de ses propres co ts de mise en uvre et l autre representee par un concurrent s interessant exclusivement a ses propres profits en tenant compte du bien etre ex ante et en raison des problemes d engagement des agences gouvernementales nous constatons qu une procedure peut s averer optimale des lors que le demandeur represente une partie a visee plus ciblee le regime optimal depend a la fois de la proportion de consommateurs naifs et du niveau des couts de mise en uvre

asymmetric information adverse selection and online disclosure the case of ebay motors since the pioneering work of akerlof 1970 economists have been aware of the adverse selection problem that information asymmetries can create in used goods markets the remarkable growth in online auctions of used goods where buyers generally purchase sight unseen therefore poses a puzzle i argue that given a means for credible information disclosure sellers will voluntarily disclose their private information to buyers through online media this limits information asymmetries and adverse selection to test this theory i examine the role of information in a large online used car market ebay motors i nd that sellers selectively disclose information that information asymmetries are reduced by these disclosures and that online media such as photos text and graphics provide a rich environment for information disclosure

quality disclosure and certification theory and practice this essay reviews the theoretical and empirical literature on quality disclosure and certification after comparing quality disclosure with other quality assurance mechanisms and describing a brief history of quality disclosure we address two sets of theoretical issues first why don t sellers voluntarily disclose through a process of unraveling and given the lack of unraveling is it desirable to mandate seller disclosure second when we rely on certifiers to act as the intermediary of quality disclosure do certifiers necessarily report unbiased and accurate information we further review empirical evidence on these issues with a particular focus on healthcare education and finance the empirical review covers quality measurement the effect of third party disclosure on consumer choice and seller behavior as well as the economics of certifiers jel d18 k32 l15 m31

when can a news organization lead public opinion ideology versus market forces in decisions to make news do news organizations purposefullylead the public to support a particularideological agenda when debating thisquestion many analysts draw conclusionsfrom weak empirical evidence we introducea model that clarifies how a newsorganization s internal structure combineswith market forces to affect when it canlead public opinion we identify conditionsunder which liberal reporters orpolitically driven media magnates canachieve ideological goals we alsoilluminate important barriers that preventmany would be public opinion leaders fromever satisfying these conditions we showthat internal structure and market forcesare critical determinants of any newsorganization s power over public opinion

information transmission when the sender s preferences are uncertain abstract in deciding on the magnitude of a certain action say investment a decision maker relies on the report of an informed and interested expert who can suppress favorable information the main departure from the related literature is that the decision maker is uncertain as to whether the expert is of a type that wants to minimize the magnitude of the action or to maximize it the unique equilibrium outcome is fully characterized by a threshold level of favorable information if the information is more favorable than that threshold level and if the expert is of the type that wants to maximize the magnitude of the action the information is fully revealed in all other cases the expert report less favorable information and the equilibrium inference is that in expectation the actual information is just as favorable as the threshold level

persuasion with communication costs this paper studies strategic transmission of verifiable information with reporting costs that continuously increase in the precision of the report contrary to previous literature it is shown that the unraveling result first derived by milgrom 1981 is relatively robust to costly reporting a separating equilibrium exists even with arbitrarily high reporting costs intuitively the costs work as a signaling device and a combination of disclosure of information and costly signaling accomplishes full separation with reporting costs there are typically multiple equilibria for example a pooling equilibrium exists if and only if the reporting costs are high finally a separating equilibrium exists when the receiver has to make a costly effort in order to access the information in a report as long as this cost is not too high

competition in persuasion we study symmetric information games where a number of senders choose what information to communicate we show that the impact of competition on information revelation is ambiguous in general we identify a condition on the information environment i e the set of signals available to each sender that is necessary and sufficient for equilibrium outcomes to be no less informative than the collusive outcome regardless of preferences the same condition also provides an easy way to characterize the equilibrium set and governs whether introducing additional senders or decreasing the alignment of senders preferences necessarily increases the amount of information revealed

legal institutions and fragile financial markets abstract this study investigates equity liquidity variation with a funding constraint across 38 countries and examines whether the effectiveness of a country s legal institutions is systematically related to cross country differences in fragile equity liquidity our results show that firms from countries with more extensive disclosure requirements tend to have lower liquidity shocks due to funding constraints leading to higher firm value this effect is stronger for ex ante disclosures especially for countries with a high level of openness and market volatility our empirical results are robust to the 2sls regression model the random effect regression model the alternative measure of fragile equity liquidity and the alternative measure of disclosure and enforcement variables our study provides a better understanding of the effect of information environments amidst periods of funding constraint

informational lobbying and political contributions abstract interest groups can potentially influence political decision makers by offering contributions and by providing relevant information that sways the decision in the group s favor what mix of these two instruments should an interest group choose and how does the use of one instrument affect the effectiveness of the other in this paper we identify an information externality that raises the cost of offering contributions and show that this indirect search cost reduces the group s incentive to gather information when contributions are allowed furthermore we analyze how competition among lobby groups as providers of information and contributions affect the choice and effectiveness of the instruments we show that the information externality rewards the group that can abstain from information search and focus its influence on contributions

are you a good employee or simply a good guy influence costs and contract design we develop a principal agent model with a moral hazard problem in which the principal has access to a hard signal the level of output and a soft behavioral signal the supervision signal about the agent s level of effort in our model the agent can initiate influence activities and manipulate the behavioral signal these activities are costly for the principal as they detract the agent from the productive task we show that the agent s ability to manipulate the behavioral signal leads to low powered incentives and increases the cost of implementing the efficient equilibrium as a result interestingly the fact that manipulation activities entail productivity losses may lead to the design of influence free contracts that deter manipulation and lead to high powered incentives this result implies that the optimal contract and whether manipulation is tolerated in equilibrium or not depends on the magnitude of the productivity based influence costs we show that it may be optimal for the principal not to supervise the agent even if the cost of supervision is arbitrarily low

strategic information revelation in fundraising abstract we consider a model of voluntary contributions for a public project with random number of potential contributors the fundraiser who observes this number has to decide whether to reveal or suppress the information before contributions are given the fundraiser s objective is to collect maximal contributions we show that whether the public project is convex or non convex can be the key to the fundraiser s announcement decision in the convex case this number is always revealed in the non convex case the number may not be revealed at all or sometimes revealed only when it is in an intermediate range in the presence of multiple equilibria total contributions increase with the extent of concealment

newspaper differentiation and investments in journalism the role of tax policy many countries levy reduced rate indirect taxes on newspapers with proclaimed policy goals of stimulating investment in journalism and ensuring low newspaper prices however by taking into account the fact that the media industry operates in two sided markets we find the paradoxical result that the consequences of a low tax regime might be quite the opposite we also show that the low tax regime tends to increase newspaper differentiation if the advertising market is relatively small the newspapers might invest too little in journalism and be too differentiated from a social point of view in this case a tax increase will be welfare enhancing

conflicts of interest information provision and competition in the financial services industry abstract in some markets sellers have better information than buyers over which products best serve a buyer s needs depending on the market structure this may lead to conflicts of interest in the provision of information by sellers this paper studies this issue in the market for financial services the analysis presents a new model of competition between banks where price competition influences the ensuing incentives for truthful information revelation we also compare conflicts of interest in two different firm structures specialized banking and one stop banking

near sighted justice chapter 11 structures complex negotiations between creditors and debtors that are overseen by a bankruptcy court we identify conditions where the court should sometimes err in determining which firms should be liquidated such errors affect actions by both good and bad entrepreneurs we first characterize the optimal error rate without renegotiation when creditors and debtors can renegotiate to circumvent an error riven court for one class of actions a blind court that ignores all information is optimal for another class the court should place the burden of proof on the entrepreneur the robust feature is that the court should sometimes err chapter 11 structures complex negotiations between creditors and debtors that are overseen by a bankruptcy court it is often unclear whether it is socially optimal for a bankrupt firm to be reorganized as a continuing entity or whether it should be liquidated and the proceeds from liquidation distributed if creditors and debtors cannot reach a settlement then the bankruptcy court may impose one this paper asks the following questions is it always optimal for the court to make the right decision if liquidation is efficient should the court always mandate liquidation if the bankrupt firm could be a profitable entity should the court always allow it to restructure under the existing management and continue or is it optimal for the court to sometimes make mistakes how does the possibility of negotiated settlements affect the optimal design of the court at one level the answers to these questions are straightforward in a world where more accurate appraisals of a firm s quality are more costly the optimal allocation by a court of resources to evaluate the bankrupt firms will always reflect trade offs between the marginal costs of better appraisals and the marginal benefit of decision making based on more accurate appraisals in this paper we show that a court should also consider how the probability that it misidentifies the quality of a bankrupt firm affects the ex ante behavior of management and hence the probability that the firm becomes bankrupt

credence goods monopolists abstract with a credence good consumers never discover how much of the good they actually need therefore the seller acts as the expert determining the customers requirements this information asymmetry creates strong incentives for the seller to cheat on services we analyze whether the market mechanism may induce non fraudulent seller behavior we consider four scenarios differing in the amount of information consumers have at hand to infer the seller s incentives to be honest in three constellations the profit maximizing credence goods monopolist provides honest services only in one scenario there is no trade

asymmetric information information externalities and efficiency the case of oil exploration in this article we examine the efect of private information and information externalities on the ex post eficiency of investment in oil exploration we show that too much drilling tends to occur ifjirms believe that the area is likely to contain a sizeable pool of oil and too little drilling occurs if the opposite is true bargaining with well defined property rights to the information externality can eliminate underinvestment but overinvestment remains a problem because firms have an incentive not to disclose their private information

should we tax or cap political contributions a lobbying model with policy favors and access abstract this paper develops a model of political contributions in which a politician can either sell policy favors or sell access access allows interest groups to share hard information with the politician in support of their preferred policy here selling access maximizes policy utility while selling policy favors maximizes total contributions imposing a binding contribution limit makes it more likely that the politician sells access which can improve expected constituent welfare however a contribution limit distorts the signals associated with the contributions which tends to result in worse policy alternatively a tax on political contributions can ensure that the politician sells access without distorting his information therefore from the viewpoint of a representative constituent a tax on contributions is strictly preferred to a contribution limit or no reform the politician however may prefer regulation in the form of a contribution limit even when a tax is better for the constituent

are biased media bad for democracy this paper assesses the normative and positive claims regarding the consequences of biased media using a political agency framework with a strategic voter polarized politicians and news providers my model predicts that voters are always better informed with unbiased than biased outlets even when the latter have opposite ideological preferences however biased media may improve voter welfare contrary to several scholars fear partisan news providers are not always bad for democracy my theoretical findings also have important implications for empirical analyses of the electoral consequences of changes in the media environment left wing and right wing biased outlets have heterogeneous effects on electoral outcomes which need to be properly accounted for existing empirical studies are unlikely to measure the consequences of biased media as researchers never observe and can rarely approximate the adequate counterfactual elections with unbiased news outlets

implementation with partial provability we extend implementation theory by allowing the social choice function to depend on more than just the preferences of the agents and allowing agents to support their statements with hard evidence we show that a simple condition on evidence is necessary for the implementation of a social choice function f when the preferences of the agents are state independent and sufficient for implementation for any preferences including state dependent with at least three agents if the social planner can perform small monetary transfers beyond those called for by f if transfers can be large f can be implemented in a game with perfect information when there are at least two players under a boundedness assumption for both results transfers only occur out of equilibrium the use of evidence enables implementation which is robust in the sense that the planner needs little information about agents preferences or beliefs and agents need little information about each others preferences our results are robust to evidence forgery at any strictly positive cost

disclosures and asset returns public information in financial markets often arrives through the disclosures of interested parties who have a material interest in the reactions of the market to the new information when the strategic interaction between the sender and the receiver is formalized as a disclosure game with verifiable reports equilibrium prices can be given a simple characterization in terms of the concatenation of binomial pricing trees there are a number of empirical implications the theory predicts that the return variance following a poor disclosed outcome is higher than it would have been if the disclosed outcome were good also when investors are risk averse this leads to negative serial correlation of asset returns other points of contact with the empirical literature are discussed

distribution and growth in an economy with limited needs variable markups and the end of work this article studies a model of the distribution of income under bounded needs utility derived from any given is bounded from above and demand is therefore not isoelastic on the other hand introducing new varieties always increases utility it is assumed that each variety is owned by a monopoly workers can specialise in material goods production or in the knowledge sector which designs new varieties as productivity increases the economy moves from a solovian zone where wages increase with productivity to a marxian zone where they paradoxically decline with productivity

relying on the information of interested parties we investigate the conventional wisdom that competition among interested parties attempting to influence a decisionmaker by providing verifiable information elicits all relevant information we find that if the decisionmaker is strategically sophisticated and well informed about the relevant variables and about the preferences of the interested party or parties competition may be unnecessary to achieve this result if the decisionmaker is unsophisticated or not well informed competition is not generally sufficient if the interested parties interests are sufficiently opposed however or if the decisionmaker is seeking to advance the parties welfare then competition can reduce or even eliminate the decisionmaker s need for prior knowledge about the relevant variables and for strategic sophistication in other settings only the combination of competition among information providers and a sophisticated skepticism is sufficient to allow effective decisionmaking

preponderance of evidence abstract this paper investigates the incentive properties of the standard of proof for a finding of negligence when evidence about injurers behavior is imperfect we show that a more likely than not decision rule provides maximal incentives for potential tort feasors to exert care an injurer is then held liable whenever inadequate care appears more likely than due care and not liable otherwise our analysis provides a deterrence rationale for the exclusionary rules of evidence found in common law and the preponderance of evidence standard of proof

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had

evidence production in adversarial vs inquisitorial regimes abstract the advantage of the adversarial regime of judicial decision making is the superior information of the parties while the advantage of an idealized inquisitorial regime is its neutrality we model the tradeoff by characterizing the properties of costly estimators used by each regime the adversarial regime uses an extremal estimator that is based on the difference between the most favorable pieces of evidence produced by each party the inquisitorial regime uses the sample mean we find that neither regime dominates the other

busy voters agenda control and the power of information t he correspondence between individual preferences and electoral outcomes is often affected by the existence of information asymmetries among electoral participants and the presence of individuals or groups who exercise some form of agenda control while the effects of agenda control in political decision making are widely recognized the effects of information asymmetries are not as well understood since information asymmetries are fundamental characteristics of most elections a deep understanding of the correspondence between individual preferences and electoral outcomes requires a serious consideration of the effects of information i develop a generalizable agenda control model that takes as given the observation that most voters are not naturally inclined to invest in political information the model allows me to provide a dynamic description of how voters and political elites can adapt to the information problems that characterize political decision making it also allows me to demonstrate the effect of these adaptations on electoral outcomes

secrecy two sided bias and the value of evidence abstract we provide necessary and sufficient conditions on players preferences for a verifiable message game to possess a separating equilibrium and or a pooling equilibrium as well as sufficient conditions for every equilibrium of such a game to be pooling we also characterize all nonseparating equilibria and use this property to show that less information might be conveyed in any equilibrium of a verifiable message game than in some equilibrium of the cheap talk game with the same parameters

willingness to pay for natural organic and conventional foods the effects of information and meaningful labels vague food labels and distorted product claims have persisted in the natural food industry while organic claims can be certified by the u s department of agriculture usda using experimental methods and a sample of randomly selected subjects we test food label and information treatment effects on subjects willingness to pay wtp for organic natural and conventional foods random nth price auctions are used to elicit wtp after subjects received one of five randomly assigned information treatments we find large information effects including asymmetric cross market effects for natural and organic foods perhaps surprising is that organic premiums increase in response to subjects seeing the natural foods industry s perspective on its products demographics effects are also important the results have practical implications for natural and organic food marketing and valuing products where there are vague claims about their attributes
