outcome based accountability theory and evidence abstract a firm s payoffs can often depend on whether it exceeds a threshold of performance in a principal agent setting we demonstrate that the optimal contract induces efficient effort by basing firing decisions solely on whether the agent was successful even though the absolute level of performance is more informative we test the predictions of our model using thirty seasons of nfl data we find that a coach is 6 percentage points more likely to be fired after a close loss beyond this the margin of victory has no significant impact on firing probabilities despite being more informative about future success also consistent with the predictions of our model coaches maximize team effort by playing their best players when doing so has the largest impact on the probability of winning

capital market development in china abstract this paper examines why and how capital markets have developed in a low income socialist country it shows that the development is the response of economic agents operating under a more market oriented economic environment with a highly regulated and inefficient banking system this development has presented new policy challenges and opportunities the paper argues that the developmental effects of the emergence of capital markets in china can be as important as its impact on improving allocative efficiency and resource mobilization

interlinked contracts and moral hazard in investment abstract in agricultural tenancy arrangements the tenant is often required to undertake effort aimed at maintaining and improving the productive stocks this paper investigate the design of contracts which induce optimal investment of such effort it is found that a long term contract which interlinks tenancy with a credit agreement is optimal in equilibrium the tenant obtains credit from the landlord at a rate of interest below the market and is perpetually indebted to the landlord

introduction imperfect information and rural credit markets puzzles and policy perspectives rural credit markets have been at the center of policy intervention in developing countries over the past forty years many governments supported by multilateral and bilateral aid agencies have devoted considerable resources to supplying cheap credit to farmers in a myriad of institutional settings the results of many of these interventions have been disappointing and one explanation for this must be that they were based on an inadequate understanding of the workings of rural credit markets the articles in this symposium issue are devoted to empirical and theoretical investigations of rural credit markets in the framework of the imperfect information paradigm the authors show how this framework is useful not only in explaining puzzling features of these markets but also in providing a policy perspective to assess the successes and failures of specific interventions

optimal taxation of flow pollutants when firms may also inflict catastrophic environmental damage in many industries firms affect the environment in two distinct types of ways firstly they emit routine anticipated volumes of flow pollutants secondly they can potentially inflict catastrophic environmental damage liability for which may be overhanging or limited by the law operaters of chemical plants nuclear power stations and oil tankers are three examples if an emissions tax or charge is to be levied on the flow pollutants in these cases how should it be set we use simple dynamic programming techniques to characterise second best optimality we identify contexts in which the tax should be raised above its pigovian level to take account of the catastrophic potential and others where it should be set below that level the analysis has significant implications for how policymakers should go about calibrating ecological taxes in a number of high profile industries

vertical coordination financial structure and the changing theory of the firm developments for evaluating these changes including the relationships to financial structure the theoretical developments include contributions from the economics of organizations stiglitz 1991 agency relationships jensen and meckling transactions cost economics williamson 1979 1985 incomplete contracting hart 1988 asymmetric information and financial contracting 1 these theoretical developments provide rich opportunities to apply new interesting concepts toward understanding and evaluating the changing managerial and organizational environment in agriculture

a liquidity based model of security design we consider the problem of the design and sale of a security backed by specified assets given access to higher return investments the issuer has an incentive to raise capital by securitizing part of these assets at the time the security is issued the issuer s or underwriter s private information regarding the payoff of the security may cause illiquidity in the form of a downward sloping demand curve for the security the severity of this illiquidity depends upon the sensitivity of the value of the issued security to the issuer s private information thus the security design problem involves a tradeoff between the retention cost of holding cash flows not included in the security design and the liquidity cost of including the cash flows and making the security design more sensitive to the issuer s private information we characterize the optimal security design in several cases we also demonstrate circumstances under which standard debt is optimal and show that the riskiness of the debt is increasing in the issuer s retention costs for assets

limited liability and incentive contracting with ex ante action choices abstract this article examines a principal agent model of financial contracting in which a risk neutral entrepreneur agent makes an unobservable ex ante effort choice while employing the investment funds of a risk neutral investor principal the key innovation is that the investment contract is subject to statutory liability limits given these liability limits two settings are considered one in which the investor payoff function is also constrained to be monotonically nondecreasing in firm profit and another in which no such monotonic contract constraint is imposed in the former case a standard debt contract is shown to emerge and a first best effort choice is not achieved in the latter setting the optimum is characterized by a live or die payoff function and a first best effort level may or may not be realized

global and domestic utilization of industrial relevant science patent citation analysis of science technology interactions and knowledge flows abstract the development of science based technologies may draw heavily on codified and tacit outputs from both domestic research bases and foreign sources having a view of the scientific underpinnings of these technical innovations and related knowledge diffusion and utilization processes especially those concerning public financed basic research is of major importance to policymakers nowadays some of those scientific and technical inputs are pivotal to technical inventions and are acknowledged as such by explicit references citations to related research papers in the reference list on the corresponding patents this case study deals with citations to dutch authored research papers on uspto patents granted during the period 1987 1996 results of the citation analysis reveal several important features of contributions made by the dutch science base to dutch invented and or foreign invented patents such as 1 a marked overall increase of patent citations to dutch research papers and 2 significant differences between domestic and foreign citation patterns where 3 domestic citation links are dominated by author inventor self citations and patents originating from the large r d intensive multinational firms such as philips these findings provide new empirical evidence that patent citation analysis produces systemic quantitative data providing strategic background information regarding nation specific and sector specific factors in domestic and cross border science technology linkages and knowledge flows

signal jamming models of fraudulent misreporting and economic prospects an experimental investigation abstract this study uses experimental methodology to examine how the frequency and magnitude with which managers commit fraud varies with economic prospects boom middle and bust the experimental design is based on signal jamming equilibrium sje models of fraud in which managers make potentially inaccurate public reports and investors bid on shares under sje managers always exaggerate reports by a fixed amount up to the maximum possible report independent of the truth shareholders can perfectly correct managers reports except for the maximum possible report in contrast the results of the experiment show four robust deviations from sje predictions 1 managers exaggerate and shareholders correct reports according to dominated mixed strategies with probabilities significantly less than one 2 managers exaggerate more frequently and by more when outcomes are poor 3 shareholders adjust low reports by less than high reports and 4 shareholders correct relatively high reports by more in booms than busts even though managers reporting strategies are invariant to economic prospects

financial constraints and firm post entry performance abstract firms finance production by internally generated funds and external loans the benefits of leverage however come with a cost this cost is related to the uncertainty banks face about the firm s quality and output price as time evolves banks learn about the firm and adjust the terms of the loan contract because of this firms do not have equal access to credit small young firms face greater binding debt constraints than more mature firms with well known prospects the firm survival rate as well as the firm rate of growth are therefore important issues in analyzing firm post entry performance

incrementality of sme loan guarantees in many countries loan guarantee programs are important elements of government policy with respect to small and medium sized enterprises smes if loan guarantee schemes are to be effective a majority of firms obtaining assistance through such a scheme ought not to be able to obtain financing from existing sources a property known as incrementality or additionality this paper describes a new approach to measuring incrementality this work uses a two stage process to estimate the incrementality of loans made under the terms of the canada small business financing csbf program first a logistic regression based model of loan outcomes essentially a credit scoring model is estimated based on a large representative sample of smes the resulting model was consistent with prior expectations and exhibited high levels of goodness of fit the model was then employed to classify a sample of firms that had received loans under the terms of the loan guarantee scheme incremental loans ought to be classified as turndowns by the model hence the proportion of loan guarantee recipients that the model classified as turndowns is a direct measure of incrementality for the csbf loan guarantee program incrementality was estimated with 95 confidence as 74 8 9 0

toward a theoretical model of voluntary overcompliance abstract we explain why some firms voluntarily overcomply with environmental regulation in our model all consumers value environmental quality but differ in their willingness to pay which depends on their income levels publicly available information on environmental performance of firms enables consumers to identify clean firms firms participate in a two stage duopoly game where they first choose their levels of cleaning technology and next engage in price competition the market gets segmented by income levels a minimum standard binding on the dirty firm has the effect of improving the performance of the cleaner firm a subsidy obtains the same competitive outcome

incentives in principal agent relationships this article identifies some of the major issues that have been examined in the literature on incentives the article begins by discussing the frictions that lie at the heart of incentive problems next the principal s optimal response to these frictions is explored taking as given the characteristics of the agents with whom the principal interacts in a nonrepeated setting the design of individualized contracts contests and tournaments is analyzed then the principal s task of selecting the best agent is addressed and repeated agency relationships are considered

earnings manipulation and the cost of capital the cost of capital the widespread use of accounting information by investors and financial analysts to help value stocks creates an incentive for managers to manipulate earnings in an attempt to influence short term stock price performance this paper examines the role of earnings management in affecting a firm s cost of capital using an agency model with multiple firms whose cash flows are correlated we demonstrate that the extent of earnings manipulation varies across the business cycle depending on a firm s earnings profile it can have stronger incentives to overstate its performance in good times or in bad times because of this dependence on the state of the economy earnings manipulation can influence a firm s cost of capital despite the forces of diversification

drivers of corporate environmentalism the case of the polish economy in transition abstract at the beginning of the 1990s the central and eastern european cee countries went through significant changes that were supposed to mould them into liberal market democracies those changes that took place in the legal institutional market and civil society fields have also significantly affected the sphere of environmental protection and management clark and cole 1998 as a result also corporate behaviour towards the natural environment has changed significantly apart from changes determined explicitly by legal developments poland has witnessed a rapid increase in voluntary corporate initiatives protecting the natural environment such as iso 14001 environmental management systems ems the purpose of this study is to uncover the drivers of corporate environmentalism as well as its specificity and dynamics during the transition period in poland in order to reach this goal 283 polish based companies were surveyed the conducted study showed that they tended to go green in order to improve their environmental performance and meet the ever changing environmental regulations expecting to capitalise on this type of corporate activity the latter was reflected in the corporate expectation to enhance their image surprisingly the research revealed that the importance of strictly economic drivers such as cost reduction and the market share was rather minor the findings also show that the pressure from various stakeholder groups was of little importance

risky debt investment incentives and reputation in a sequential equilibrium the agency relationship of corporate insiders and bondholders is modeled as a dynamic game with asymmetric information the incentive effect of risky debt on the investment policy of a levered firm is studied in this context in a sequential equilibrium of the model a concept of reputation arises endogenously resulting in a partial resolution of the classic agency problem of underinvestment the incentive of the firm to underinvest is curtailed by anticipation of favorable rating of its bonds by the market this anticipated pricing of debt is consistent with rational expectations pricing by a competitive bond market and is realized in equilibrium some empirical implications of the model for bond rating debt covenants and bond price response to investment announcements are explored

contracting with imperfect commitment and noisy communication abstract this paper provides new analytical tools for studying principal agent problems with adverse selection and limited commitment by allowing the principal to use general communication devices we overcome the literature s common but overly restrictive focus on one shot direct communication in addition general communication devices solve two fundamental problems of contracting with imperfect commitment first they allow us to identify the local downward incentive constraints as the relevant ones if the agent s preferences satisfy a single crossing property second we show how one may restrict the cardinality of the message spaces of the communication device an example illustrates our arguments and the suboptimality of one shot direct communication

comparative statics of the optimal dynamic incentive contract abstract each period a firm must carry out an indivisible project the cost of which depends on the firm s constant efficiency and its variable level of effort only the cost is observed by the regulator who has to choose the incentive scheme the optimal dynamic mechanism is derived under possible commitment of the regulator over time then under non commitment it is shown that there are four types of continuation equilibria also the profile of effort levels is compared to the commitment case finally some numerical comparative statics is performed and it is shown that all types of equilibria can be optimal

an analysis of offer functions of banks and credit unions in guatemala economists have sought to identify institutions which might fill the gap in household access to credit arising from rationing by formal lenders credit unions have been identified as institutions which might use informational and monitoring advantages to fill that gap using information on household perceptions of their access to credit this article analyses the impact of certain credit unions on the access to credit of households in guatemala regression results indicate that credit unions serve markets unserved by formal lenders and that information on household perceptions of their access to credit is important in making inferences about lender lending activities

contractual contingencies and renegotiation in a dynamic model of asymmetric information between the owner of a firm and a manager we investigate the optimal set of contingencies on which an incentive contract should depend when renegotiation is possible in particular we characterize the circumstances in which the contracting parties find it desirable to deliberately restrict what the owner can monitor thereby limiting the contractible contingencies our findings thus provide an endogenous explanation for contract simplicity in contrast to those based on transactions costs or bounded rationality

credit rationing concessionary lending and debt maturity abstract a firm raises capital for a two period investment while creditors observe the project status midstream unobservable managerial perks may consume capital each period when the firm is unfortunate early on short term financing results in either concessionary lending or costly liquidation rolling over short term debt may be problematic because the high risk premium creditors demand when asset value is low relative to debt impares managerial motivation precisely when the incentive to defer perk consumption is weakest long term financing may reduce total agency costs be enabling lenders to charge higher initial premia in effect shifting loan repayments to states in which incentive constraints are non binding

moral hazard and secured lending in an infinitely repeated credit market game we analyze repeated moral hazard with discounting in a competitive credit market with risk neutrality even without learning or risk aversion long term bank borrower relationships are welfare enhancing the main result is that the borrower obtains an infinite sequence of unsecured loans at below spot market cost following the first good project realization this contract produces first best action choices prior to this stage the borrower gets secured loans with above market borrowing cost the optimal contract thus displays a selective memory feature taking only one of two forms at any given point in time depending on prior history we consider an infinitely repeated bank borrower relationship with moral hazard and universal risk neutrality and explore the ramifications of credit contract duration when the two well known benefits of long term contracting learning and improved risk sharing are absent our objectives are twofold the first is to analyze an infinitely repeated game with discounting in a credit market context we thus relate the theory of repeated games to financial intermediation theory particularly to issues of moral hazard and collateral related distortions the second objective is to understand noteworthy stylized facts of credit markets such as durability in credit relationships lower borrowing costs for established borrowers and unsecured loans for established borrowers versus secured loans for newer borrowers while these practices may be partly due to learning we show that learning is not essential to rationalize them even if information decays rapidly and banks learn nothing about borrowers through time these aspects of credit contracting arise in a repeated game context our main results are as follows first despite universal risk neutrality and the absence of learning a durable bank relationship benefits the borrower 2 the intuition is that the long term contracting permitted by a durable relationship enables the bank to efficiently tax and subsidize the borrower through time to reduce the use of costly collateral second the average welfare loss due to moral hazard per period is positive even as the time horizon goes to infinity third the optimal infinite horizon contract has the striking property that following the period

capital requirements monetary policy and aggregate bank lending theory and empirical evidence capital requirements linked solely to credit risk are shown to increase equilibrium credit rationing and lower aggregate lending the model predicts that the bank s decision to lend will cause an abnormal runup in the borrower s stock price and that this reaction will be greater the more capital constrained the bank i provide empirical support for this prediction the model explains the recent inability of the federal reserve to stimulate bank lending by increasing the money supply i show that increasing the money supply can either raise or lower lending when capital requirements are linked only to credit risk the motivation of this article is first to examine the impact of risk based capital requirements namely those that link mandatory capital to asset ratios for banks to their loans on aggregate bank lending these requirements called the basle capital rules or bis guidelines went into effect in march 1989 for banks in the leading industrialized nations these rules initially required banks to maintain capital equal to 7 25 percent of business and most consumer loans with the requirement increasing to 8 percent by the end of 1992 secondly i wish to understand the link between monetary policy and aggregate bank credit in the presence of risk based capital requirements my curiosity is sparked in part by two recent phenomena one is the experience of the u s economy which displayed sluggish growth during 1989 93 despite a monetary policy that attempted to spur bank lending and economic activity and the other is the striking decline in loans relative to security holdings mostly government bonds in the asset portfolios of u s

the economics of workout lending lenders are forced to consider a workout loan when a borrower loses access to financial markets and must seek loans from existing creditors to continue servicing outstanding loans a model of the loan decision is developed that distinguishes socially useful from socially wasteful workout loans the analysis is extended to examine two collective action problems that may arise when many lenders have claims on a troubled borrower the paper concludes with a consideration of the implications of the model for the establishment of prudential lending limits and of policies to stimulate new lending to troubled debtor countries copyright 1989 by ohio state university press

equilibria with communication in a job market example we study costless information transmission from a job applicant to an employer who must decide whether to hire him and if so which position to give him we construct equilibrium payoffs requiring at least two signaling steps or even that no deadline be imposed on the plain conversation the set of communication equilibrium payoffs achieved with the help of a communication device is larger than the set of equilibrium payoffs of the plain conversation game but coincides with the set of correlated equilibrium payoffs

adverse selection in dynamic moral hazard this paper studies a multiperiod moral hazard problem under two assumptions i contracts are subject to renegotiations ii the agent s action has long term effects the action is also interpreted as a choice of characteristic or type renegotiation proof contracts that implement various actions including random ones are characterized under appropriate conditions the equilibrium involves the principal implementing a random action therefore the equilibrium has standard properties of adverse selection models

epa s voluntary 33 50 program impact on toxic releases and economic performance of firms abstract this paper examines the motivations for participation in the voluntary 33 50 program and the program s impact on the toxic releases and economic performance of firms in the u s chemical industry it demonstrates that the benefits due to public recognition and the potentially avoided costs of liabilities and compliance under mandatory environmental regulations provide strong incentives for participation after controlling for sample selection bias and the impact of other firm specific characteristics this paper shows that program participation led to a statistically significant decline in toxic releases over the period 1991 93 the program also had a statistically significant negative impact on the current return on investment of firms but its impact on the expected long run profitability of firms was positive and statistically significant

adverse selection and renegotiation in procurement as was shown by dewatripont optimal long term contracts are generally not sequentially optimal the parties ex post renegotiate them to their mutual advantage this paper fully characterizes the equilibrium of a simple two period procurement situation and studies the extent to which renegotiation reduces ex ante welfare i a central result is that like in the non commitment case the second period allocation is optimal for the principal conditionally on his posterior beliefs about the agent ii the first period allocation exhibits an increasing amount of pooling when the discount factor grows iii with a continuum of types it is never optimal to induce full separation the paper also analyzes whether renegotiated long term contracts yield outcomes resembling those under either unnegotiated long term contracts or a sequence of short term contracts and it links the analysis with the multiple unit durable good monopoly problem

the dynamics of incentive contracts the paper studies a simple two period principal agent model in which the principal updates the incentive scheme after observing the agent s first period performance the agent has superior information about his ability the principal offers a first period incentive scheme and observes some measure of the agent s first period performance cost or profit which depends on the agent s ability and unobservable first period effort the relationship is entirely run by short term contracts in the second period the principal updates the incentive scheme and the agent is free to accept the new incentive scheme or to quit the strategies are required to be perfect and updating of the principal s beliefs about the agent s ability follows bayes rule the central theme of the paper is that the ratchet effect leads to much pooling in the first period first for any first period incentive scheme there exists no separating equilibrium second when the uncertainty about the agent s ability is small the optimal scheme must involve a large amount of pooling the paper also gives necessary and sufficient conditions for the existence of partition equilibria and looks at the effect of cost uncertainty

technology policy and global warming why new policy models are needed or why putting new wine in old bottles won t work in recent years the threat of global climate change has come to be seen as one of the most serious confronting humanity to meet this challenge will require the development of new technologies and the substantial improvement of existing ones as well as ensuring their prompt and widespread deployment some have argued that the urgency of the situation requires a manhattan project or an apollo program this paper examines why such a policy model is inappropriate arguing that the nature of the policy context for confronting climate change necessitates a different kind of technology policy than that for building an atomic bomb or for achieving a manned lunar landing instead it seeks to draw lessons from three sectors that seem to be more pertinent and where government technological development and deployment programs have been pursued with some success in the united states namely agriculture biomedical research and information technology it compares and contrasts these with the policies pursued with regard to the first two of these sectors in the united kingdom the paper concludes by drawing out the implications for the design of policies supporting technological development and innovation to address the problem of global climate change

corporate fraud and investment distortions in efficient capital markets inefficient investment allocation induced by corporate fraud where informed insiders strategically manipulate outside investors beliefs has been endemic historically and has recently attracted much attention we reconcile corporate fraud and investment distortions with efficient capital markets building on shareholder manager agency conflicts and investment renegotiation in active takeover markets because investments that are ex post inefficient are not renegotiation proof the optimal renegotiation proof contract induces overstatements by managers accompanied by overinvestment in low return states and underinvestment in high return states by rational investors our framework also helps explain why easy access to external capital appears to facilitate corporate fraud

why japanese firms choose to certify a study of managerial responses to environmental issues abstract this paper examines empirically the determinants that led large japanese manufacturers to 1 incorporate environmental goals in their decisions 2 obtain environmental certification iso 14001 and 3 become early adopters of environmental certification we estimate two sets of models 1 models based on a profit maximization assumption and 2 models which incorporate utility maximization arguments recognizing that managers values attitudes and beliefs may also influence firms decisions the empirical analysis suggests that while the costs and benefits of voluntary actions to enhance or protect the environment and the capacity to act are significant determinants of voluntary environmental commitment so are the environmental values beliefs and attitudes of managers

the incentive effects of dismissals efficiency wages piece rates and profit sharing the relation of several incentive schemes to productivity is studied with a particular emphasis on the effects and determinants of dismissals dismissals turn out to be positively but in a nonlinear way associated with productivity similarly profit sharing raises productivity wages and piece rates are insignificant profit sharing decreases the number of dismissals made by firms copyright 1991 by mit press

collateral and competitive equilibria with moral hazard and private information the authors examine equilibrium credit contracts and allocations under different competitivity specifications and explain the economic roles of collateral under these specifications both moral hazard and adverse selection are considered the principal message is that how a competitive equilibrium is conceptualized significantly affects the characterization of equilibrium credit contracts specifically some well known results in the rationing literature are shown to rest delicately on the adopted equilibrium concept two somewhat surprising results emerge first high quality borrowers with unlimited collateral may be priced out of the market despite the bank having idle deposits second high quality borrowers may put up more collateral this paper explores the allocational consequences of alternative credit market competitivity specifications and explains the different economic roles of collateral under these specifications we model banks that lend to borrowers financing projects with payoffs depending on a priori unknown borrower attributes and ex post unobservable borrower actions borrowers are assumed to have unconstrained access to collateral our analysis is based on two concepts of competitive equilibrium under both banks compete in the sense that they earn zero expected profits however under the first concept of equilibrium ti as in jaffee and russell 11 all rents accrue to borrowers whereas under the second concept t2 all rents accrue to depositors as in stiglitz and weiss 17 our research makes two main points first we demonstrate that the manner in which a competitive equilibrium is conceptualized importantly influences the characterization of equilibrium credit allocations specifically one of the findings is that the rationing equilibria of stiglitz and weiss 17 and others should be viewed as rather delicate things in that they are very sensitive to the competitivity specification used for instance

competition risk neutrality and loan commitments abstract we rationalize fixed rate loan commitments forward credit contracting with options in a competitive credit market with universal risk neutrality future interest rates are random but there are no transactions costs borrowers finance projects with bank loans and choose ex post unobservable actions that affect project payoffs credit contract design by the bank is the outcome of a non cooperative nash game between the bank and the borrower the initial formal analysis is basically in two steps first we show that the only spot credit market nash equilibria that exist are inefficient in the sense that they result in welfare losses for borrowers due to the bank s informational handicap second we show that loan commitments because of their ability to weaken the link between the offering bank s expected profit and the loan interest rate enable the complete elimination of informationally induced welfare losses and thus produce an outcome that strictly pareto dominates any spot market equilibrium perhaps our most surprising result is that if the borrower has some initial liquidity it is better for the borrower to use it now to pay a commitment fee and buy a loan commitment that entitles it to borrow in the future rather than save it for use as inside equity in conjunction with spot borrowing

the economics of fraudulent accounting we argue that earnings management and fraudulent accounting have important economic consequences in a model where the costs of earnings management are endogenous we show that in equilibrium low productivity firms hire and invest too much in order to pool with high productivity firms this behavior distorts the allocation of economic resources in the economy we test the predictions of the model using firmlevel data we show that during periods of suspicious accounting firms hire and invest excessively while managers exercise options when the misreporting is detected firms shed labor and capital and productivity improves our firm level results hold both before and after the market crash of 2000 in the aggregate our model provides a novel explanation for periods of jobless and investment less growth

is work special justice and the distribution of employment i investigate from an egalitarian welfarist standpoint the issue of whether state guaranteed employment should be offered as a matter of right to able bodied poor citizens who suffer chronic or persistent unemployment an affirmative answer is defended one consideration supporting this right to work is that provision of transfer aid in the form of jobs rather than cash screens nonneedy bohemians from the class of beneficiaries the main conclusion of the essay is defended from one objection based on efficiency wage models of the labor market and from another based on the alleged impossibility of maintaining the self respect and self esteem of able bodied individuals who fail to earn their own keep independently in a market economy

toxics release information a policy tool for environmental protection abstract this study examines investor reactions to the repeated public disclosure of environmental information about firms in the chemical industry and the effectiveness of this information as a decentralized mechanism for deterring their pollution by allowing investors to benchmark the performance of firms repeated provision of the toxics release inventory led firms to incur statistically significant negative stock market returns during the one day period following the disclosure of that information in the years 1990 1994 these losses had a significant negative impact on subsequent on site toxic releases and a significant positive impact on wastes transferred off site but their impact on total toxic wastes generated by these firms is negligible

information and economic analysis a perspective ten years ago i delivered a paper before this group with the title information and economic analysis i chose the title deliberately i did not call the subject on which i was speaking the economics of information because to do so would have been to suggest that my topic like the economics of agriculture or the economics of industry or the economics of labour represented another branch of specialisation within economics i wanted to suggest that informational considerations were in fact central to the analysis of a wide variety of phenomena that they constituted a central part of the foundations of economic analysis at the time though economists had long paid lip service to the importance of information there was little formal literature the last decade has seen a burgeoning of the literature it has become to the late 7o s and early 8o s what growth theory was to the early 6o s and it has been greeted with some of the same scepticism there seems to be a myriad ofspecial cases and few general principles the little examples are often contrasted unfavourably with the generality of general equilibrium theory what have we learned have diminishing returns set in are there fruitful directions for future research and if so what are they these are the questions which i wish to address here the work of the past decade has made i think a fundamental and lasting contribution to economic analysis the contributions have been both negative and positive we have learned that much of what we believed before is of only limited validity that the traditional competitive equilibrium analysis though having the superficial appearance of generality in terms of superscripts and subscripts is indeed not very general the theory is not robust to slight alterations in the informational assumptions it is but a special and not very plausible example among the possible set of informational assumptions which can be employed to characterise an economy at the same time the theory has been able to provide insights into phenomena about which the traditional model had nothing to say or which seemed inconsistent or inexplicable within the competitive paradigm it has provided some of the micro foundations for macro economics it has provided the basis of a new theory of the firm of a new new welfare economics and of a theory of economic organisation including a comparison of economic

credit layering in informal financial markets abstract informal lenders with access to markets or capital often find it attractive to delegate loan provision to downstream lenders who have an information or enforcement advantage in dealing with particular borrowers in this paper we examine the conditions under which such an arrangement is preferred by two informal lenders a landlord and a merchant who compete in loan provision to tenant farmers differentiated by wealth we show that credit layering is preferred only when tenants are sufficiently poor in this case the trader lends to tenant farmers via a contract with their landlord otherwise only the trader lends as a consequence a pattern of borrowing emerges in which relatively wealthy tenants borrow from merchants while poor tenants borrow mainly from their landlords interlinkage between land and credit thus arises only for a subset of tenants and purely as a consequence of credit layering this pattern is shown to be supported empirically

the impact of performance based compensation on misreporting abstract this paper examines the effect of ceo compensation contracts on misreporting we find that the sensitivity of the ceo s option portfolio to stock price is significantly positively related to the propensity to misreport we do not find that the sensitivity of other components of ceo compensation i e equity restricted stock long term incentive payouts and salary plus bonus have any significant impact on the propensity to misreport relative to other components of compensation stock options are associated with stronger incentives to misreport because convexity in ceo wealth introduced by stock options limits the downside risk on detection of the misreporting

a great wall of patents what is behind china s recent patent explosion abstract china s patent surge documented in this paper is seemingly paradoxical given the country s weak record of protecting intellectual property rights using a firm level data set that spans the population of china s large and medium size industrial enterprises this paper explores the factors that account for china s rising patent activity while the intensification of research and development in the chinese economy tracks with patenting activity it explains only a fraction of the patent explosion the growth of foreign direct investment in china is prompting chinese firms to file for more patent applications amendments to the patent law that favor patent holders and ownership reform that has clarified the assignment of property rights also emerge as significant sources of china s patent boom these results are robust to alternative estimation strategies that account for over dispersion in the patent counts data and firm heterogeneity

the impact of environmental management on firm performance environmental management has the potential to play a pivotal role in the financial performance of the firm many individuals suggest that profitability is hurt by the higher production costs of environmental management initiatives while others cite anecdotal evidence of increased profitability a theoretical model is proposed that links strong environmental management to improved perceived future financial performance as measured by stock market performance the linkage to firm performance is tested empirically using financial event methodology and archival data of firm level environmental and financial performance significant positive returns were measured for strong environmental management as indicated by environmental performance awards and significant negative returns were measured for weak environmental management as indicated by environmental crises the implicit financial market valuation of these events also was estimated cross sectional analysis of the environmental award events revealed differences for first time awards and between industries first time award announcements were associated with greater increases in market valuation although smaller increases were observed for firms in environmentally dirty industries possibly indicative of market skepticism this linkage between environmental management and financial performance can be used by both researchers and practitioners as one measure of the benefits experienced by industry leaders and as one criterion against which to measure investment alternatives

real economy effects of short term equity ownership investor time horizon varies by company industry and economic system in this article we explore the importance of this variation by studying the impact of shareholder time horizon on the investment decisions of the firms they own and externalities on the wider market we demonstrate theoretically that short term shareholders cause boards to care about the path of the stock price rationalising firms pursuit of investments for signalling reasons at the expense of long term value we demonstrate that short termism has spillover effects leading to higher costs of equity capital bubbles in the price of input assets and predictable excess returns we build testable cross country hypotheses and evaluate these using existing evidence coupled with a new dataset on owner duration of us and germanic firms

environmental accidents under moral hazard and limited firm liability we study optimal government policy when firms operations involve a risk of a large environmental accident firms do not have sufficient assets to cover such costs and the risk is affected by firms efforts which are unobservable to outsiders when firms profits and government revenues have equal weights in the social welfare function a first best can be implemented and requires that the firm be subsidized heavily when operating with no accident and all its assets confiscated in the event of an accident with a lower weight on firm profits the solution is always second best with lower subsidies to the firm and a firm effort lower than at the first best solution when firm investments affect both the required accident preventing effort for given risk and the work effort required for a given output the first best never involves specific investment subsidies while a second best solution generally always does

linking the technological regime to the technological catch up analyzing korea and taiwan using the us patent data this article examines the relationship between the technological regime and the technological catch up using us patent data this study first extends the notion of technological regimes as more appropriate for the catching up context before it goes on to develop the quantitative expressions of technological regime variables then it investigates in which technological classes technological catch up tends either to occur or not to occur and what affects the speed of the catch up this study has found that catching up is more likely to happen in those technological classes with shorter technological cycle time and more initial stock of knowledge and that among those candidate classes the actual speed of catch up varies depending on appropriability and knowledge accessibility this implies that the factors that determine the occurrence of catch up and the speed of catch up are different comparing the level of technological capability of the advanced and catching up economies the article has found that catching up countries tend to achieve high levels in the technological sectors with shorter cycle time easier access to knowledge and higher appropriability whereas the advanced countries show the exactly opposite performances the study also confirms the organizational selection hypothesis such that the firms of different organizations and strategies show divergent degrees of fitness in the different environment or technological regime we find that the korean firms find themselves more fitted to technological regimes featured by low appropriability and high cumulativeness persistence whereas the taiwanese firms are more fitted to technological regimes featured by high appropriability and low cumulativeness persistence our findings are consistent with the following characterization of the firms in korea and taiwan the korean firms dominated by the so called chaebols especially in patent registrations are characterized as less flexible large diversified conglomerates and pursing more independent r d and learning strategies the taiwanese firms are characterized as more flexible network based specialized firms and pursuing more cooperative r d and learning strategies copyright 2006 oxford university press

optimal capital structure and investment with real options and endogenous debt costs we examine the joint optimization of financial leverage and irreversible capacity investment in a real options framework with risky debt and endogenous interest costs higher capacity ceteris paribus increases operating leverage and default probability but lowers ex post adjustment costs and generates larger tax shields a key insight is that financial leverage and capacity are substitutes in the debt market equilibrium we develop novel predictions about the effects of capital adjustment costs operating costs and uncertainty on optimal financial leverage and capacity that may potentially help explain ambiguous empirical results in the literature regarding the determinants of capital structure and investment received march 17 2016 editorial decision july 8 2017 by editor itay goldstein

theoretical foundations for sticky wages abstract the paper compares three different types of theoretical explanation of sticky wages they are implicit contracts efficiency wage models and insider outsider models it then reconsiders keynes rationale for sticky wages which focuses on relative wage issues finally the paper considers possible directions for future research

peer monitoring and credit markets a major problem for institutional lenders is ensuring that borrowers exercise prudence in the use of the funds so that the likelihood of repayment is enhanced one partial solution is peer monitoring having neighbors who are in a good position to monitor the borrower be required to pay a penalty if the borrower goes bankrupt peer monitoring is largely responsible for the successful financial performance of the grameen bank of bangladesh and of similar group lending programs elsewhere but peer monitoring has a cost it transfers risk from the bank which is in a better position to bear risk to the cosigner in a simple model of peer monitoring in a competitive credit market this article demonstrates that the transfer of risk leads to an improvement in borrowers welfare

dynamic microlending under adverse selection can it rival group lending we derive an optimal lending contract in a two period adverse selection model with limited commitment on the borrower side the contract involves penalty interest rates after default and favorable rates after success under some conditions it also charges first time borrowers higher rates than repeat borrowers as in relationship lending because the lender is constrained to keep borrowing attractive while using revealed information to price for risk we compare the efficiency of a group lending contract of the kind popularized by the microcredit movement to the dynamic individual contract both types of contracts reveal the same information but the contracts face different constraints on using the information to improve risk pricing as a result either type of contract can lead to greater efficiency depending on specifics of the environment opening the possibility that dynamic lending has played a role comparable to that of group lending in the success of microcredit we also characterize the optimal dynamic group contract when both lending techniques are feasible and find that it combines both approaches but with varying emphases a recurrent theme is that in more marginal environments dynamic lending performs relatively better than and is prioritized over group lending we also discuss a number of extensions including spatially and serially correlated risk and the effect of competition

intertemporal incentives under loss aversion this paper studies the intertemporal allocation of incentives in a repeated moral hazard model with reference dependent preferences as in k oszegi and rabin 2009 besides consumption utility the agent experiences utility from the change in his beliefs about present and future eort and income when eort plans are rational the prospect of being disappointed by the outcome realization equals that of being pleasantly surprised and hence the loss averse agent is on net hurt by news in contrast to the prediction with classical preferences but consistent with real world contracts if consumption utility is not too concave and news about present income carries suciently larger weight in utility than news about future income a contract setting a current

the deterrence effects of vicarious punishments on corporate financial fraud this study extends the research on corporate financial fraud by developing a new perspective on the deterrence effects of vicarious punishments premised on social learning theory we posit that firms vicariously learn about punishments from their peers by picking up modeling cues environmental cues and social cues in the inhibitive learning process thus being deterred from committing future fraudulence using a matched sample of 604 observations of chinese listed firms between 2002 and 2008 our findings show that an observing firm is deterred from committing fraud if the peers in its industry are caught and punished we further find that such deterrence effects are subject to how the observing firm evaluates the possibility of being caught and the likelihood it will be punished the same way if it violates similar prohibitions in particular inhibitive learning effects are positively moderated by punishments of prominent firms and model observer similarity but negatively attenuated by the development of the legal system our study sheds light on the corporate fraud literature by illuminating the indirect inhibitive learning process from vicarious punishments and identifying the conditions for differential learning deterrence outcomes of the observing firms

short term contracting and strategic oil reserves the effect of short term contracting on resource extraction is studied in a two country model of international trade in oil countries planners are assumed to be fully rational with perfect information and perfect foresight contracts are assumed perfectly enforceable and complete except that short term contracts do not allow commitments to actions taken beyond the contract period we show that short term contracting limits countries opportunities for intertemporal consumption smoothing reducing their collective tolerance for temporal variation in consumption this tends to make them extract more slowly than in the efficient plan that results from long term contracting contractual relationships often outlive the contracts that govern them it is therefore common for a long term relationship to be governed by a sequence of short term contracts when these contracts allow complete control of the organization of the relationship within each contract period any outcome that can be achieved in a long term contract covering the entire life of the relationship is also feasible with a sequence of short term contracts short term contracting can nevertheless have significant effects on resource allocation because each contract must be voluntarily negotiated in the environment created by its predecessors an allocation that is acceptable to both parties as a long term contract might not be voluntarily negotiable as a sequence of short term contracts because short term contracting is so prevalent it is worth asking what sorts of relationship can be organized efficiently only by long term contract and what kinds of distortion are caused by short term contracting two kinds of answers to these questions have been given in the literature one important line of investigation considers the use of memory in contracts designed to control parties incentives under asymmetric information baron and besanko 1985 rubinstein and yaari 1983 sanchez and zapater 1985 stiglitz and weiss 1983 tirole 1986 and townsend 1982 among others have shown how parties can use

information institutions and banking sector development in west africa i introduction banks and other financial intermediaries can perform an important developmental function especially in africa where alternative sources of finance are limited or nonexistent by providing firms with essential finance they help them to take advantage of productive investment opportunities which may not otherwise materialize by screening loan applicants they can help to address adverse selection in the credit market and channel funds toward productive uses by monitoring borrowers they can contain moral hazard behavior for example excessively risky investment activity that could undermine a borrower s ability to repay a loan through long term bank borrower relationships well established banks can address both adverse selection and moral hazard this not only helps banks to remain solvent but also ensures that bank finance is channeled toward productive and sound investments there is a large body of empirical evidence which suggests that the development of banking systems goes hand in hand with economic development see e g levine 2004 although the evidence on causality is mixed see e g demetriades and hussein 1996 there is broad consensus that well functioning banking systems promote economic growth demetriades and andrianova 2005 it is therefore a puzzle that so many countries remain financially underdeveloped this is particularly true of sub saharan africa which remains one of the most financially under developed regions in the world a recent study by the world bank has shown that african banking systems lack depth compared to other regions in the world but are also excessively liquid honohan and beck 2007 according to the world bank banks themselves complain that there is a lack of creditworthy borrowers while at the same time households and firms find finance to be a major constraint the evidence presented by the world bank also suggests that the least developed banking systems are also the most liquid suggesting that excess liquidity is a common feature of financial under development this article aims to shed light on these features of financial under development in africa utilizing a panel data set comprising the banks operating in the west african economic and monetary union uemoa during 2000 2005 the uemoa provides a uniform financial system across eight countries the structure of this system has changed little in the last 15 years therefore we can be sure that the variations in bank behavior we observe within the uemoa are not because of variations in the nature of public financial institutions which the banks face this makes feasible the identification of the institutional sources of the variations in bank behavior which are not correlated with variations in the quality of public financial institutions our data set includes balance sheet information on each bank in the uemoa including bank characteristics such as age and ownership type profitability and the number of urban and rural branches we also utilize country level data on loan defaults which provides information on the average quality of borrowers we use this as a proxy for the severity of information problems faced by banks in the credit market we combine this information with macroeconomic data including institutional quality indices constructed by the world bank our data set enables us to examine the extent to which informational and institutional factors and interactions between different factors can explain a bank s loans to assets ratio which is an inverse measure of bank liquidity our data set is also used to examine the microeconomic and macroeconomic determinants of the total volume of assets of an individual bank which is a good micro level indicator of overall banking sector development our results suggest that to a large extent financial under development including excess liquidity and low banking sector development can be attributed to severe informational problems

optimal contracts when enforcement is a decision variable this paper analyzes choice theoretic costly enforcement in an intertemporal contracting model with a differentially informed investor and entrepreneur an intertemporal contract is modeled as a mechanism in which there is limited commitment to payment and enforcement decisions the goal of the analysis is to characterize the effect of choice theoretic costly enforcement on the structure of optimal contracts the paper shows that simple debt is the optimal contract when commitment is limited and costly enforcement is a decision variable theorem 1 in contrast stochastic contracts are optimal when agents can commit to the ex ante optimal decisions theorem 2 the paper also shows that the costly state verification model can be viewed as a reduced form of an enforcement model in which agents choose payments and strategies as part of a perfect bayesian nash equilibrium

competing lending platforms endogenous reputation and fragility in microcredit markets this paper shows that market fragility and mass default can arise in microcredit markets as a result of the strategic interaction between a microlender using a reputation based mechanism and a traditional lender using physical collateral in our model borrowers solve a dynamic programming problem which induces an endogenous equilibrium distribution of reputational capital because the quality of each lender s pool of borrowers is affected by both lenders interest rates lender reaction curves are non monotonic and discontinuous this can result in knife edge equilibria and mass default on the microlender precipitated by minor parametric perturbations fragility is exacerbated by borrower screening and sovereign risk but ameliorated when microlenders have social welfare goals our results highlight the importance of studying the entire credit market rather than microfinance in isolation

can neoclassical economics underpin the reform of centrally planned economies te here s a curious symmetry between the arguments propounded over the last century in advocacy of socialism and the present popular discussion of the reform of centrally planned economies in those old discussions the vision of socialism was utopian which was contrasted with the dickensian realities of capitalism now the disasters of central planning are contrasted with the benefits flowing from perfectly functioning markets in the conventional wisdom of reform the vision of markets is utopian and that of central planning concentrates on the awful reality what is largely missing in the conventional wisdom is a satisfactory attempt to come to grips with the central question that should be answered in formulating reform plans how does one explain the differences in performance of market capitalist and centrally planned economies of course capitalism has outperformed central planning the developed west is therefore an obvious source of ideas for reforms but the institutions of capitalism come in many varieties and cannot be put in place instantaneously there are many alternative reform paths depending upon the importance attributed to each of these institutions thus there remains the problem of tracing the source of the superiority of capitalist economies to specific characteristics this point was made clear to me on hearing a vietnamese official justify single party rule by noting the economic success of taiwan and singapore reformers need a filter that interprets the experience of capitalist and socialist systems this is exactly where economic theory plays a vital role

knowledge flows in the solar photovoltaic industry insights from patenting by taiwan korea and china abstract in this paper we extend work previously undertaken in industries such as semiconductor and flat panel displays to investigate knowledge flows from advanced countries us japan and europe to catch up follower countries taiwan korea and china this time in the emergent solar photovoltaic industry the solar photovoltaic industry is of particular interest in that it is poised between exploitation of first generation crystalline silicon technologies and new thin film and organic compound technologies thus providing distinct sources of knowledge flow as measured by patent citations and linkage for this study we deploy a new database of 19 105 solar photovoltaic patents taken out by taiwan korea and china at the uspto over the 24 years 1984 2008 and analyse the knowledge flows revealed in these patents using a set of 12 international patent classification technology categories that we constructed we demonstrate commonalities in patterns of knowledge flow between solar photovoltaic and earlier industries but also suggestive differences such as rising dependence of the catch up countries on their own intra national knowledge generation and flow indicating their shift from imitation to innovation

the life cycle of a microfinance institution the irish loan funds abstract ireland s loan funds were a long lived self sustaining large scale microfinance organization that made millions of loans without collateral to the poor during the first 100 years of their life cycle a period of growth ending in the 1840s they adapted constantly and obtained improvements to their legal structure because they were complementary to the banking system and seen as effective in relieving poverty in their 2nd century they became ossified in part because of competition with commercial banks the loan funds provide an example of sustainable microfinance under harsh economic conditions and illustrate how organizations change incrementally and when successful alter their institutional framework

equilibrium credit rationing of small farm agriculture it is often argued that externally imposed contractual restrictions lead to inequitable credit rationing this paper argues that unrestricted laissez faire markets may also inequitably ration credit a formal model which grants borrowers autonomy in credit application and use demonstrates that adverse incentive and selection effects may cause banks to endogenously impose interest rate restrictions and ration small farms out of the credit market consequently liberalization of financial markets may be insufficient to guarantee small farms access to credit

voluntary environmental agreements good or bad news for environmental protection abstract there has been growing interest in the use of voluntary agreements vas as an environmental policy tool this article uses a simple model to determine whether vas are likely to lead to efficient environmental protection we consider cases where polluters are induced to participate either by a background threat of mandatory controls the stick approach or by cost sharing subsidies the carrot approach the results suggest that the overall impact on environmental quality could be positive or negative depending on a number of factors including the allocation of bargaining power the magnitude of the background threat and the social cost of funds

optimal design of securities under asymmetric information a firm must decide what security to sell to raise external capital to finance a profitable investment opportunity there is ex ante asymmetry of information regarding the probability distribution of cash flow generated by the investment in this setting we derive necessary and sufficient conditions for a security to be optimal uniquely optimal that is for pooling at this security to be an the unique equilibrium outcome using these conditions we show that the debt contract is uniquely optimal if and only if cash flows are ordered by strict conditional stochastic dominance finally we derive an equivalence relationship between optimal security designs and designs that minimize mispricing
