attention misallocation social welfare and policy implications we examine how agents allocate attention between private and public signals to reduce the uncertainty about observation noises when coordination is an important concern in this setting the attention allocation may not be monotone in endowed attention capacity agents may decrease their attention on or even ignore the more accurate signal when capacity increases as a result social welfare may decrease when they have more attention to process information and it can be even higher when agents possess a finite amount of capacity than when they have an infinite amount of capacity we derive sufficient and necessary conditions under which multiple equilibria emerge and study the implications of equilibrium multiplicity for macroeconomic policies

what is a relationship worth repeated exchange and the development and deployment of relational capital organization scholars have highlighted the value of relationships in fostering effective exchange suggesting that repeated exchange creates a relational asset with latent value derived from elevated social connections norms and simple expectations of exchange continuity yet the empirical evidence supporting such claims remains largely indirect as a consequence few studies have been able to directly examine how contextual factors shape the accumulation of this relational asset or define its value in application we directly measure the value of relationships between suppliers and a large buyer using the buyer s choices in internet enabled procurement auctions to estimate the degree to which stronger relationship histories with suppliers increase willingness to pay for high volume commodity like parts our setting also allows us to examine how this willingness to pay for relationships is shaped by the social context in which they develop and by the exchange context in which they are subsequently depl

public procurement with unverifiable quality the case for discriminatory competitive procedures unverifiable quality may affect the enforcement of procurement contracts even when the award procedure is able to select the most efficient firm in the market in this paper we show that a discriminatory competitive mechanism which awards the contract on the basis of price and firms past performance yields an efficient allocation of the contract and allows the buyer to implement her desired quality quality enforcement arises out of relational contracting whereby the buyer handicaps a contractor in future competitive tendering processes if it fails to provide the required quality we study an infinitely repeated procurement model with two firms and one buyer imperfectly informed on the firms cost in which in each period the buyer runs a discriminatory auction we restrict our analysis to the case of a buyer committed to her handicapping strategy a case which captures some of the features of a public buyer when players use either grim trigger or stick and carrot strategies we find that the buyer can induce the delivery of optimal unverifiable quality with a variety of handicap levels and when applicable durations of the punishment period for some values of the handicap and the length of the punishment period both firms remain active in the market even when punished

golden parachutes shark repellents and hostile tender offers a common view of golden parachutes and shark repellents is that they are designed by management to insulate itself from the discipline imposed by the market for corporate control and so are harmful to shareholders this paper offers an alternative view that these devicesare beneficial to shareholders because they allow better contracting between manager and shareholders evidence on the incidence of goldenparachutes and on the compensation tenure relationship for managers of golden parachute firms supports the alternative view copyright 1986 by american economic association

reputation and the allocation of ownership we show that allocation of ownership matters even in a long term relationship where problems of opportunism are less severe unless agents are very patient ownership structure is chosen to give the agents best incentives to cooperate the optimal control structure of the static game restricts the gain from deviation to be the lowest but also the punishment will be minimal the worst ownership structure of the one shot game is good in the repeated setting because it provides the highest punishment but bad because the gain from deviation is also highest we show that when investment costs are very elastic partnership and a hostage type solution arise in equilibrium while when costs are moderately elastic the results of the one shot game apply

knowing what others know coordination motives in information acquisition we explore how optimal information choices change the predictions of strategic models when a large number of agents play a game with strategic complementarity information choices exhibit complementarity as well if an agent wants to do what others do they want to know what others know this makes heterogeneous beliefs di cult to sustain and may generate multiple equilibria in models with substitutability agents prefer to difierentiate their information choices we use these theoretical results to examine the role of information choice in recent price setting models and to propose modeling techniques that ensure equilibrium uniqueness

rewarding performance by promotion to a different job abstract use of promotions rather than performance related pay to provide incentives can be justified if performance is non verifiable information this does not explain why promotion is to a different job rather than simply a better paid job the effectiveness of tournaments is undermined however if unsuccessful workers are equally suited to higher paid jobs and can engage in bribery or other influence activity a promotion based reward structure with pay tied to jobs can be made immune to such activity if misallocations of employees to jobs are costly to the firm

the existence of self enforcing implicit contracts implicit contracts are nontrivial nash equilibria to the post hiring trading game between a worker and the employer these are supported by intrafirm rather than labor market reputations the existence of an implicit contract that supports efficient trade is proved in a simple model

the interaction of implicit and explicit contracts in repeated agency abstract in a repeated principal agent model in which the agent s actions are observable to the principal but not verifiable in court the agent s incentives derive both from salary payments based on verifiable signals and from implicit promises by the principal of bonuses for good behavior explicit short term contracts are designed to enhance the effectiveness of the infinite horizon implicit contract between principal and agent in a constrained efficient equilibrium bonuses smooth the consumption path of the risk averse agent by moving in the opposite direction from salaries total consumption and expected discounted utility for the rest of the game journal of economic literature classification numbers c7 c73 d8

the firm as a dedicated hierarchy a theory of the origins and growth of firms in the formative stages of their businesses entrepreneurs have to provide incentives for employees to protect rather than steal the source of organizational rents we study how the entrepreneur s response to this problem determines the organization s internal structure growth and its eventual size large steep hierarchies will predominate in physical capital intensive industries and will have seniority based promotion policies by contrast e at hierarchies will prevail in human capital intensive industries and will have up or out promotion systems furthermore e at hierarchies will have more distinctive technologies or cultures than steep hierarchies the model points to some essential differences between organized hierarchies and markets at the root of most enterprises generating economic surplus is an entrepreneur with a unique critical resource such as an idea good customer relationships a new tool or superior management technique a fundamental problem of entrepreneurship is how to enlist the cooperation of the many agents necessary for production without ceding to them too much of the surplus generated by the enterprise the risk of being expropriated however is always inherent in production in particular the entrepreneur has to give her employees whom we call managers close proximity or access to the critical resource for them to learn to produce effectively for example a manager has to understand the idea be in contact with the key customers and suppliers or even learn the entrepreneur s unique managerial techniques in order to work effectively but access also gives the manager the opportunity to expropriate this critical resource and compete against the entrepreneur managers may steal the idea walk away with clients or mimic the entrepreneur s management style and start up a rival concern the greater the access a manager has the more he can appropriate and the more effectively he can compete this paper explores the role of organizational design in

reputation and discretion in financial contracting the authors explain the use of legally unenforceable discretionary financial contracts in circumstances where legally enforceable contracts are feasible a discretionary contract allows a contracting party to choose whether or not to honor the contract it is shown that such a contract liquefies reputational capital by permitting it to be depreciated in exchange for the preservation of financial capital and information reusability in financially impaired states in addition discretionary contracts foster the development of reputation this explains discretion among highly confident letters holding company relationships mutual fund contracts bank loan commitments and other financial and nonfinancial contracts copyright 1993 by american economic association

moral hazard in high office and the dynamics of aristocracy both aristocratic privileges and constitutional constraints in traditional monarchies can be derived from a ruler s incentive to minimize expected costs of moral hazard rents for high officials we consider a dynamic moral hazard model of governors serving a sovereign prince who must deter them from rebellion and hidden corruption which could cause costly crises to minimize costs a governor s rewards for good performance should be deferred up to the maximal credit that the prince can be trusted to pay in the long run we find that high officials can become an entrenched aristocracy with low turnover and large claims on the ruler dismissals for bad performance should be randomized to avoid inciting rebellions but the prince can profit from reselling vacant offices and so his decisions to dismiss high officials require institutionalized monitoring a soft budget constraint that forgives losses for low credit governors can become efficient when costs of corruption are low

relational incentive contracts standard incentive theory models provide a rich framework for studying informational problems but assume that contracts can be perfectly enforced this paper studies the design of self enforced relational contracts i show that optimal contracts often can take a simple stationary form but that self enforcement restricts promised compensation and affects incentive provision with hidden information it may be optimal for an agent to supply the same inefficient effort regardless of cost conditions with moral hazard optimal contracts involve just two levels of compensation this is true even if performance measures are subjective in which case optimal contracts terminate following poor performance jel c73 d82 l14

on reputation a microfoundation of contract enforcement and price rigidity we study the impact of reputational incentives in markets characterised by moral hazard problems social preferences have been shown to enhance contract enforcement in these markets while at the same time generating considerable wage and price rigidity reputation powerfully amplifies the positive effects of social preferences on contract enforcement by increasing contract efficiency substantially this effect is however associated with a considerable bilateralisation of market interactions suggesting that it may aggravate price rigidities surprisingly reputation in fact weakens the wage and price rigidities arising from social preferences thus in markets characterised by moral hazard reputational incentives unambiguously increase mutually beneficial exchanges reduce rents and render markets more responsive to supply and demand shocks

productive low morale abstract this paper models employment relationship as a repeated principal agent problem with private evaluation the efficient contracts exhibit correlated movements between lagged wage and current effort that are consistent with the positive feedback between pay and morale in practice low morale therefore is an integral part of a well functioning relationship

incentives between firms and within this paper reviews the significant progress in agency theory i e the economic theory of incentives during the 1990s with an eye toward applications to supply transactions i emphasize six recent models in three pairs 1 new foundations for the theory of incentive contracts 2 new directions in incentive theory and 3 new applications to supply transactions by reviewing these six models i hope to establish three things first the theory of incentive contracts needed and received new foundations second new directions in incentive theory teach us that incentive contracts are not the only source of incentives finally and especially relevant to supply transactions the integration decision is an instrument in the incentive problem

the hardships of long distance relationships time zone proximity and the location of mnc s knowledge intensive activities abstract using a unique global dataset on multinational corporations mncs with precise location of headquarters and affiliates i present evidence of a trade off between distance to the headquarters and knowledge intensity of the affiliates economic activity this trade off is strongly diminished the higher the overlap in working hours between the headquarters and the affiliate in order to rule out biases arising from confounding factors i implement a regression discontinuity framework to show that the economic activity of a subsidiary located just across the time zone line which increases the overlap in working hours with its headquarters is on average roughly 1 higher on the knowledge intensity scale the results are present only for foreign horizontal subsidiaries overall the findings suggest that barriers to real time communication within mncs play an important role in the location decisions of their subsidiaries

subjective evaluations with performance feedback this paper models two key roles of subjective performance evaluations their incentive role and their feedback role the paper shows that the feedback role makes subjective pay feasible even without repeated interaction as long as there exists some veri able measure of performance it also shows that while subjective pay is helpful it cannot achieve full e ciency however fully e cient incentives are achievable if the rm can commit to a forced distribution of evaluations and employs a continuum of workers with a small number of workers a forced distribution is valuable only if the veri able measure is poor

endogenous verifiability and relational contracting for contracting parties it will often be uncertain whether a legal court is able to enforce the real intents of their contract the strict requirements of verifiability make it costly if not impos sible for parties to arrange their transactions and design their contract in a way that makes it completely protected by the court a way out is then to rely on self enforcing relational con tracts through repeated transactions the parties can make it costly for each other to breach the contract by letting breach ruin future trade but the self enforcing range of contracts is limited so the court s ability to enforce a contract is not without consequence for the contracting parties if possible the parties may thus have incentives to take costly actions that affect the ability of the court both ex ante preparations in terms of detailed contracting and ex post revelation of informa tion can increase the probability of fair court enforcement in this paper we focus on the former assuming that the parties are able to improve the verifiability of the contracted actions by care ful ex ante contract specifications we assume that careful contracting can improve the court s ability to verify whether an action conforms to the one described in the contract then we ask what happens to the self enforcing contract equilibrium if a party takes actions ex ante that affect the probability of verification in order to provide some answers we analyze a simple repeated principal agent game where the verifiability of the agent s actions is endogenously determined by the principal s investments in drafting an explicit contract pertaining to the quality of the agent s output the model makes it possible to identify some subtle effects of two key enforcement devices legal courts and repeated interaction note that by endogenizing verifiability we also endog enize the degree of contractual incompleteness and the equilibrium level of incompleteness will depend on the verification technology i e the resource costs that are necessary to achieve various verifiability levels this verification technology will be influenced in an essential way by the quality of courts in fact we can use the model to study relationships between two distinct aspects of courts namely their ability which influences the verification technology and their predictability which manifests itself in the equilibrium level of verifiability i e the probability with which the court in fact will verify the relevant action the repeated game approach formalizes an economic concept of trust and trustworthiness since a party honors trust if the present value of honoring exceeds the present value of abusing it the discount factor is then a proxy for the trust level in the relationship by studying the effect of variations in verification technology and the discount factor we can gain insight into the rela tionship between court ability explicit contracting trust and relational contracting below we summarize the results

multilateral contracting and the employment relationship this paper studies the structure of the employment relationship in organizations it investigates the trade off firms face between making commitments to their workforce as a whole multilateral relational contracts and making more limited commitments to individuals or smaller groups of employees bilateral relational contracts multilateral contracts bind the firm more strongly to implicit commitments improving motivation but are difficult to adjust in response to changes in the environment bilateral contracts make workforce changes easier to implement the framework helps to explain the use of relative performance evaluation why firms rely on temporary employees and the adoption of two tier workforces

technology choice relative performance pay and worker heterogeneity abstract we identify a new problem that may arise when heterogeneous workers are motivated by relative performance pay if workers abilities and the production technology are complements the firm may prefer not to adopt a more advanced technology even though this technology would costlessly increase each worker s productivity due to the complementarity between ability and technology under technology adoption the productivity of a more able worker increases more strongly than the productivity of a less able colleague as a consequence both workers motivation to exert effort is reduced we show that this adverse incentive effect is dominant and consequently keeps the firm from introducing a better production technology if talent uncertainty is sufficiently high and or monitoring of workers is sufficiently precise

labor contracts under asymmetric information when workers are free to quit this paper examines the impact of workers ability to quit on the performance of labor contracts between workers and privately informed firms while the need to induce workers to remain with the firm necessarily lowers total welfare the effect on employment levels is to reduce the magnitude of the inefficiency due to asymmetric information whether this inefficiency is under or overemployment the model predicts that employment distortions increase with the strength of lock in effects on workers a prediction which contrasts with the results of efficiency wage models and which may help in empirical testing of labor contract theory

information choice technologies theories based on information costs or frictions have become increasing popular in macroeconomics and macro finance the literature has used various types of information choices such as rational inattention inattentiveness information markets and costly precision using a unified framework we compare these different information choice technologies and explain why some generate increasing returns and others particularly those where agents choose how much public information to observe generate multiple equilibria the results can help applied theorists to choose the appropriate information choice technology for their application and to understand the consequences of that modeling choice

drive out fear unless you can drive it in the role of agency and job security in process improvement understanding the wide range of outcomes achieved by firms trying to implement total quality management tqm and similar process improvement initiatives presents a challenge to management theory a few firms reap sustained benefits from their programs but most efforts fail and are abandoned in this paper i study one dimension of this phenomenon the role of impending layoffs in determining employee commitment to process improvement currently the literature provides two opposing theories concerning the effect of job security on the ability of firms to implement change initiatives the drive out fear school argues that firms must commit to job security while the drive in fear school emphasizes the positive role that insecurity plays in motivating change in this study a contract theoretic model is developed to analyze the role of agency in process improvement the main insight of the study is that there are two types of job security internal and external that have opposing impacts on the firm s ability to implement improvement initiatives the distinction is useful in explaining the results of different case studies and can reconcile the two change theories

works councils and employment growth in german establishments using data from german manufacturing establishments this article examines the relationship between works councils and employment growth taking the endogeneity of councils into account the estimates show a positive growth effect of works councils this suggests that the performance enhancing voice role of german works councils dominates their monopoly role moreover the findings of this study support the hypothesis that workers are more likely to implement a council to protect their quasi rents when the establishment is facing a long term crisis copyright the author 2009 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

courts and contract enforcement in transition agriculture theory and evidence from poland abstract the paper investigates theoretically and empirically the role of courts for contract enforcement in transition agriculture in a survey of 306 polish farmers conducted in 1999 only 38 5 respondents reported to believe that they could use courts to enforce contracts with their most important customer furthermore those who believed the legal system could be used would accept significant financial losses before taking action we develop a theoretical model based on the costs and benefits of court enforcement which captures the boundary between contracts to be regarded as enforceable and not enforceable and simultaneously the threshold of taking legal action the empirical analysis strongly supports our model 1 the farmers responses can be explained by cost benefit calculations regarding the use of courts 2 the legal enforceability of contracts depends not only on the efficiency of the legal system but also on the attributes of the transaction the contracts and the relationship between buyer and seller and 3 the threshold of taking legal action is significantly influenced by indirect costs of court enforcement such as the disruption of a valuable business relationship and by the availability of alternative enforcement mechanisms

did american welfare capitalists breach their implicit contracts during the great depression preliminary findings from company level data it has been claimed that american employers experiments in private welfare capitalism collapsed during the great depression giving place to the welfare state and industrial unionism recent studies however reveal considerable differences in experience across firms the author of this study who characterizes private welfare capitalism as a set of human resource management practices constituting an implicit contract equilibrium tests the implications of implicit contract theory using data from fourteen leading manufacturing firms the repudiation of implicit contracts she finds was positively correlated with the severity of the depression s impact experienced by firms and negatively correlated with the effectiveness of internal enforcement mechanisms instituted by firms furthermore she finds that greater breaches of implicit contracts were associated with greater employee support for industrial unions and more explicit employment contracts concluded under the new deal a comparative case study c

human capital and self enforcing contracts this essay analyzes labor contracts as a device for rearranging factor incomes over time under conditions of extreme adverse selection in particular the lack of verifiable public information about future compensation prevents finitely lived workers from borrowing against their earnings specific human capital is used as an incentive to implement intertemporal self enforcing contracts between workers and firms after proposing a necessary and sufficient condition for the existence of such contracts the resulting equilibrium earnings profiles are explored along with the effects of imperfections in the credit market on the way workers choose jobs and allocate time between current production and training copyright 1988 by the editors of the scandinavian journal of economics

wage secrecy as a social convention there is a time to keep silent and a time to speak out ecclesiastes 3 7 ask anyone who works for a living how much money he or she makes and you are likely to encounter a range of responses from evasion to outright hostility such responses however should not be surprising according to organizational etiquette it is considered gauche to ask others their salaries in a study at e i du pont de nemours all employees were asked if the company should disclose more payroll information so that everyone would know everyone else s pay only 18 voted for an open pay system dolan and schuler 1987 315 m any organizations have strict policies and norms about the secrecy of pay it is seen as inappropriate in most companies for employees to talk about what they earn and data are rarely given out even internally on salaries some organizations even fire individuals who release salary data this is one way to make it very clear that the organization means it when it says it believes in pay secrecy lawler 1990 239 t he issue of openness or secrecy in the communication of compensation information is one of the most important issues facing senior management henderson 1985 379 i introduction despite the general belief that a free flow of information enhances efficiency social convention appears to call for secrecy regarding individuals wages this paper provides an explanation for this convention we suggest that the role of wage secrecy is to reduce effective labor mobility and thereby enhance the feasibility of risk shifting contracts wage secrecy may yield a mix of mobility and risk shifting that is superior both to a spot market for labor and to a social convention that binds workers to their employers in promising to pay a worker a pre agreed wage rate labor contracts shift uncertainty from workers to employers and provide workers with insurance in particular if workers are risk averse and firms are risk neutral such contracts may enhance the welfare of workers without imposing a cost on firms since a risk shifting contract shields workers from the vicissitudes of the market wage rates need not equal the marginal product of labor in good outcomes workers pay the firm an insurance premium by accepting a wage rate that is lower than their marginal product in bad outcomes workers collect on their insurance policy earning a wage rate that exceeds their marginal product 1 if workers can move freely from one firm to another however risk shifting labor contracts may not be feasible given such freedom of movement workers will stay with their firm if the wage rate exceeds that offered elsewhere and move if they can obtain a higher wage rate in another firm hence without restrictions on labor mobility risk shifting contracts will not be offered and wage rates will vary with the marginal product of labor in this case the market in labor is a spot market the risk shifting role of labor contracts may be salvaged by a social convention that binds workers to their firms this would require that a worker who leaves his employer earlier than the accepted norm would be viewed as breaking a social convention and develop a damaging reputation we shall refer to this type of convention as a binding convention 2 it appears that a binding convention is assumed in most of the implicit contract literature binding however comes at a cost while facilitating risk shifting it may lead to inefficient resource allocation with a binding convention the tradeoff between the loss in output and the extent of workers exposure to risk depends on the nature of risks faced by the firm when the only risk that firms face is an aggregate shock defined as a shock that affects all firms in a sector in the same way binding does not reduce production efficiency if the marginal product of labor is the same in all firms the worker s place of employment does not affect output

governance reform in legal service markets this paper discusses proposed governance reforms of legal services markets the model distinguishes between a status quo position supported by a system of professionally enforced collective reputation and forms of governance based more squarely on market mechanisms we identify a number of forces which determine the success of reform focussing particularly on the rent recapture and relationship substitution effects we highlight their impact on client welfare and quality of legal services in different types of market according to whether clients are transient or repeated users of the service

consumer inertia choice dependence and learning from experience in a repeated decision problem abstract understanding when and how individuals think about real life problems is a central question in economics this paper studies the role of inertia inattention state dependence and learning the empirical setting is a tariff experiment when optional measured tariffs for local telephone calls were introduced unanticipatedly we find that consumers tend to align their choices of tariff and telephone use levels correctly despite low potential savings mistakes are not permanent as individuals actively engage in tariff switching in order to reduce the monthly cost of telephone service ignoring unobservable heterogeneity and the endogeneity of past choices would have reversed these results

implicit contracts incentive compatibility and involuntary unemployment this paper considers the enforceability of employment contracts when employees performance cannot be verified in court so that piece rate contracts are not legally enforceable part i shows that there exists a variety of self enforcing implicit contracts modelled as perfect equilibria in a repeated game and characterizes all the wage and performance outcomes that can be implemented implementation requires a strictly positive surplus from employment the form of the contract depending on how this surplus is divided between firm and employee piece rate contracts and contracts with an informally agreed bonus can be made self enforcing but the use of severance pay and bonding does not extend the set of implementable allocations the resulting contracts resemble actual labor contracts more than do the contracts in standard principal agent models part ii analyses market equilibrium with these contracts also modelled as perfect equilibria in a repeated game and shows that many such equilibria exist unfilled vacancies and unemployed workers can co exist despite the existence of contracts that are potentially mutually beneficial for those jobs that are filled any division of the potential surplus is possible so that the market can have at the same time involuntary unemployment and vacancies that are unfilled despite filled jobs earning positive profits as a criterion for selecting equilibria a notion of renegotiation proofness is applied then either all workers are employed or all jobs filled but any division of the potential surplus is still possible the paper explores what further restrictions on beliefs give rise to a walrasian outcome in which all the potential surplus goes to the short side of the market and to an efficiency wage type outcome in which the potential surplus goes to the long side

optimal sticky prices under rational inattention this paper presents a model in which price setting firms decide what to pay attention to subject to a constraint on information flow when idiosyncratic conditions are more variable or more important than aggregate conditions firms pay more attention to idiosyncratic conditions than to aggregate conditions when we calibrate the model to match the large average absolute size of price changes observed in micro data prices react fast and by large amounts to idiosyncratic shocks but only slowly and by small amounts to nominal shocks nominal shocks have strong and persistent real effects we use the model to investigate how the optimal allocation of attention and the dynamics of prices depend on the firms environment jel e 3 e5 d8

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

strategic pricing with rational inattention to quality this paper studies both theoretically and experimentally the pricing strategy of a rm that faces a consumer who is rationally inattentive to product quality sims 2003 in a standard sequential pricing game rational inattention to quality produces two types of mixed strategy perfect bayesian equilibria one where sellers pool at a low price and buyers are fully inattentive to quality and one where there is semi pooling at a high price and buyers are selectively attentive to quality i characterize these

informational frictions and commodity markets this paper develops a model with a tractable log linear equilibrium to analyze the effects of informational frictions in commodity markets by aggregating dispersed information about the strength of the global economy among goods producers whose production has complementarity commodity prices serve as price signals to guide producers production decisions and commodity demand our model highlights important feedback effects of informational noise originating from supply shocks and futures market trading on commodity demand and spot prices our analysis illustrates the weakness common in empirical studies on commodity markets of assuming that different types of shocks are publicly observable to market participants
