the governance of global value chains unresolved human rights environmental and ethical dilemmas in the apple supply chain the continued advance of global value chains as the mode of production for an increasing number of goods and services has impacted considerably on the economies and societies both of the developed world and the emerging economies although there have been many efforts at reform there is evidence of unresolved dilemmas of human rights environmental issues and ethical dilemmas in the operation of the global value chain this paper focuses on the role and performance of apple inc in the global value chain in asia apple is the most successful corporation on earth measured in financial terms and yet has failed to find a solution to recurrent employment and environmental problems occurring in plants manufacturing apple components this analysis informs the current theoretical debate on the development of the global value chain and the continuing institutional failure that leaves employees vulnerable and the environment neglected

redistribution policy and the expansion of the public sector abstract during the first part of this century life cycle and insurance type considerations seem to have dominated redistribution policy in particular when we look at the consequences for the expansion of public spending by contrast during recent decades fragmented horizontal redistributions between various minority groups have probably been the most important mechanisms the self interest of different groups of the electorate seems to have provided the most powerful motive behind these various policies although welfare altruism and what in this paper are called considerations of consequential externalities have probably been important motives behind redistribution in favor of the poor

can mergers ensure the survival of credit unions in the third millennium abstract the survival of small financial institutions in the third millennium depends on their competitiveness against large bank rivals accordingly credit unions in australia and the united states have attempted to increase efficiency through mergers our paper uses the data envelopment analysis methodology to evaluate the post merger gains in technical and scale efficiency achieved by 31 australian credit union mergers in 1993 1994 and 1994 1995 relative to non merging credit unions when compared with the only us study of credit union mergers journal of banking finance 23 1999 367 386 our findings suggests that mergers are not associated with improvements in efficiency superior to those achieved by internal growth

firm reputation and horizontal integration author s cai hongbin abstract we study effects of horizontal integration on firm reputation in an environment where customers observe only imperfect signals about firms effort quality choices firms cannot maintain reputations of high quality and earn quality premium forever even when firms are choosing high quality effort there is always a possibility that a bad signal is observed in this case firms must give up their quality premium at least temporarily as punishment a firm s integration decision is based on the extent to which integration attenuates this necessary cost of maintaining a good reputation horizontal integration leads to a larger market base for the merged firm and may allow better monitoring of the firm s choices hence improving the punishment scheme for deviations on the other hand it gives the merged firm more room for sophisticated derivations we characterize the optimal level of integration and provide sufficient conditions under which nonintegration dominates integration we show that the optimal size of the firm is smaller when 1 trades are more frequent and information is disseminated more rapidly or 2 the deviation gain is smaller than the honesty benefit or 3 customer information about firm choices is more precise

corporate social responsibility theories mapping the territory the corporate social responsibility csr field presents not only a landscape of theories but also a proliferation of approaches which are controversial complex and unclear this article tries to clarify the sit uation mapping the territory by classifying the main csr theories and related approaches in four groups 1 instrumental theories in which the corporation is seen as only an instrument for wealth creation and its social activities are only a means to achieve economic results 2 political theories which concern themselves with the power of corporations in society and a responsible use of this power in the political arena 3 integrative theories in which the corporation is focused on the satisfaction of social demands and 4 ethical theories based on ethical responsibilities of corporations to society in practice each csr theory presents four dimensions related to profits political performance social demands and ethical values the findings suggest the necessity to develop a new theory on the business and society relationship which should integrate these four dimensions

the risk of contagion from multimarket contact abstract it is conventional wisdom that the strategic linkage of markets that is enabled by multimarket contact typically increases the profitability of cooperation among rivals we find to the contrary that a strong force against strategic linkage results from imperfect monitoring of adherence to cooperation with such imperfections strategically linking markets can lower payoffs by permitting the impact of adverse shocks in one market to spread to others consequently players of repeated games on more than one front may find it strictly advantageous to avoid linking strategies on a front with clear monitoring to outcomes on a front with error prone monitoring one implication is that antitrust competitive strategy and foreign policy analyses have presumed too broadly that multimarket contact fosters cooperation the game theoretic equilibria characterized here shed light on why players such as firms and nations sometimes strategically link fronts in their rivalry and sometimes take care to articulate that some fronts of particularly volatile conflicting interests will not trigger broader adverse moves against the rival

financial sustainability and poverty outreach within a network of village banks in cameroon a multi dea approach abstract microfinance institutions face a double bottom line they perform financial tasks by giving microcredits to their customers and support projects aiming at reducing poverty in doing so they have to be financially self sufficient and to target poor people excluded from the traditional financial systems however a trade off may exist between financial sustainability and poverty outreach for these institutions by using a multi dea approach this paper shows that even if a trade off exists for 15 of the mc 2 mutuelles communautaires de croissance in cameroon there is no trade off for 46 of them in order to increase without trade off financial and social performance of inefficient mc 2 a benchmarking approach combing dea and performance indicators has been developed dea is used for identifying best practices and setting benchmarking goals performance indicators are used for characterizing areas needing improvements and following the evolution of mc 2 toward their goals i e for implementing benchmarking complementarity of both approaches provides a tool box for improving financial and social efficiency and reducing the trade off between financial sustainability and poverty outreach of microfinance institutions

government spending and taxation what causes what in the past few years as federal deficits have risen to high nominal levels economists have argued about the effect that raising taxes ostensibly to reduce deficits might have on government spending some economists including milton friedman have argued that raising taxes will simply lead to more spending others including james buchanan and richard wagner have said that the high deficits themselves have been responsible for the growth of federal spending and that if that spending had to be financed completely by direct taxes people would demand that the federal government spend less a third group led by robert barro says that increased taxes and borrowing are results of increased government spending in section ii we briefly review various hypotheses about the relationship between federal government spending and revenues section iii describes the testing procedure used to discriminate between these hypotheses the results of four tests are presented in section iv section v contains a summary and major conclusions to foreshadow what follows we find no evidence that higher real federal taxes today lead to either higher or lower federal spending tomorrow on the other hand we find strong evidence that higher spending now will lead to higher taxes later our results support a view of the world in which the political system somehow determines how much to spend and then looks for revenue sources to finance that level of spending including direct taxation borrowing and money creation we also find evidence that real federal revenues are positively affected by real gross national product gnp real federal spending also rises with real gnp but it appears to be independent of the rate of inflation

role of linking mechanisms in multitask agency with hidden information we investigate the adverse selection problem where a principal delegates multiple tasks to an agent we characterize the virtually implementable social choice functions by using the linking mechanism proposed by jackson and sonnenschein 2007 that restricts the message spaces the principal does not require any incentive wage schemes and can therefore avoid any information rent and welfare loss we show the resemblance between the functioning of this message space restriction and that of incentive wage schemes we also extend the results of the single agent model to the multi agent model

global cartels leniency programs and international antitrust cooperation in this paper we analyze cartel formation and self reporting incentives when firms operate in several geographical markets and face antitrust enforcement in different jurisdictions we are concerned with the effectiveness of leniency programs and the benefits of international antitrust cooperation between agencies when international antitrust prosecution is uncoordinated multi market contact allows firms to reduce the amount of self reporting in equilibrium and sustain cartels more effectively we then discuss the effects of information sharing among antitrust authorities as a function of how much and which type of information is exchanged we show that extensive information sharing might have an adverse effect on self reporting by cartel members

i don t want to be green prosocial motivation effects on firm environmental innovation rejection decisions although the political and consumer consciousness has turned increasingly green many firms continue to resist the adoption of environment friendly technological innovations even in the face of higher costs negative health effects and stricter government oversight this article examines how business owners weigh the trade offs associated with environment friendly innovations by examining the role of prosocial motivation in their decision making process we use primary data to overcome a common restriction in studying environmental innovations the scarcity of relevant data to analyze how business owners expectations perceptions and motivations affect innovation in organizational processes and consequently the level of environmental friendliness of their products or services we found that prosocial motivation had a significant negative impact on innovation adoption and that it is expressed differently under high and low levels of customer compatibility possibly because business owners have a larger number of competing social objectives and priorities our results further showed that the innovation s ability to satisfy downstream customer demands has the greatest impact on environment friendly innovation adoption decisions by business owners this study enhances our understanding of how business owners make innovation decisions based on competing business environmental and social objectives and provides a foundation for future research in this area

leniency programs for multimarket firms the effect of amnesty plus on cartel formation we examine the effect of amnesty plus on dynamic cartel formation in a multimarket setting the amnesty plus program has been adopted as part of the us corporate leniency policy in 1999 and is now vigorously advertised as one of the most compelling tools in generating successful cartel investigations amnesty plus is aimed at attracting amnesty applications by encouraging firms convicted in one market to report their collusive agreements in other markets we show that amnesty plus has two opposite effects on firms ability and incentives to collude which are both increasing in the fine reduction granted first amnesty plus can reduce the deterrence of cartel activities by making it easier for firms to sustain multimarket collusion through strategies involving self reporting after a first cartel detection second it can reduce the expected duration of cartels or delay their formation by increasing firms incentives to self report after a first cartel detection

the size and composition of government expenditure abstract this paper tests several leading hypotheses on determinants of government expenditure the purpose is to avoid omitted variables bias by testing the prominent theories in a comprehensive specification to identify persistent puzzles for the current set of theories and to explore those puzzles in greater depth by looking at the composition of government expenditure and the level of government at which it takes place as well as its magnitude using government financial statistics data from the imf covering over 100 countries from 1970 2000 i look at cross sectional and inter temporal variation in government expenditure and both individual categories of expenditure such as defense education health care and different levels of government central and local among other results i find a new explanation for wagner s law widespread evidence that preference heterogeneity leads to decentralization rather than outright decreases in expenditures that a great deal of the expenditure associated with increased trade openness is not in categories that explicitly insure for risk and evidence that both political access and income inequality affect the extent of social insurance

what global emission regulations should corporations support in their role as political actors and lobbyists corporations have responsibilities to help determine the existence and content of global regulations of pollutants the ethical nature of those responsibilities is highly sensitive to the assumed normative framework this paper compares several frameworks by modeling them as differently weighted versions of utilitarianism under a strict neoclassical approach corporations have a narrow obligation to maximize profits which generally entails opposing emission regulations in contrast a stakeholder approach as well as marxian and common ethics approaches suggest that firms have an obligation to actively support sustainable emission regulations with the following properties major restrictions would be global rather than local global restrictions would apply in all cases of persistent emissions global restrictions would apply to non persistent emissions as well unless they have been affirmatively shown to be safe using reasonably persuasive scientific evidence safety thresholds would be set fairly restrictively based on administrative models and rules of thumb in light of existing scientific knowledge but without requiring full scientific justification long run goals would include zero emission of persistent unsafe substances

the politics of shareholder activism in nigeria shareholder activism has become a force for good in the extant corporate governance literature in this article we present a case study of nigeria to show how shareholder activism as a corporate governance mechanism can constitute a space for unhealthy politics and turbulent politicking which is a reflection of the country s brand of politics as a result we point out some translational challenges and suggest more caution in the diffusion of corporate governance practices across different institutional environments we contribute to the literature on corporate governance in africa whilst creating an understanding of the political embeddedness of shareholder activism in different institutional contexts i e a step closer to a political theorising of shareholder activism

mismanagement or mismeasurement pitfalls and protocols for dea studies in the financial services sector abstract dyson et al dyson r g allen r camanho a s podinovski v v sarrico c s shale e a 2001 pitfalls and protocols in dea european journal of operational research 132 245 259 suggest that the application of dea presents a range of problems and they suggest that the systematic collection and reporting of these problems would significantly enhance dea practice it is widely accepted that dea studies may be compromised by the problem of data heterogeneity while this problem is expected in studies that cross national boundaries it may also arise in studies for a single country there can for example be significant market and regulatory differences between regions within a single country using a sample of australian credit unions this paper demonstrates the pitfalls and protocols of using dea it is intended that the guidelines provided in this study will enhance dea practice in the financial services sector

living by the golden rule multimarket contact in the u s airline industry this paper examines empirically the effects of multimarket contact on pricing in the u s airline industry the analysis of the time series and cross sectional variability of airline fares in the 1000 largest domestic city pair routes reveals the presence of statistically significant and quantitatively important multimarket effects fares are higher in city pair markets served by carriers with extensive interroute contacts these findings are consistent with the claims of industry experts that airlines live by the golden rule i e that they refrain from initiating aggressive pricing actions in a given route for fear of what their competitors might do in other jointly contested routes during his testimony mr steven b elkins senior director of marketing systems development for northwest airlines cited an example in which northwest lowered fares on night flights that were flying with empty seats in a number of routes from minneapolis and upper midwest cities to various west coast cities he said that continental airlines swiftly responded by cutting prices in important northwest markets mr elkins s memo advises northwest pricing analysts we will live by the golden rule in his testimony he explained that the golden rule in that context was that i did not want my pricing analyst initiating actions in another carrier s market like chicago for fear of what that other carrier might do to retaliate wall street journal october 9 1990 p b1

tests of a rational theory of the size of government in many countries the political party holding power changes more frequently than the trend growth rates in government spending and taxes shifts of political power are often preceded by rhetoric about meeting needs or cutting taxes which post election performances rarely match yet changes in the size of government up and down occur on average the size of government measured by the share of taxes or spending to output has increased in many countries during the past century but changes in size occur at diffrent rates and at times the relative size of government declines

is ethical finance the answer to the ills of the uk financial market a post crisis analysis the 2008 financial crisis exposed the dark side of the financial sector in the uk it brought attention to the contaminated culture of the business which accommodated the systemic malpractices that largely contributed to the financial turmoil of 2008 in the wake of the crisis there seems to be a wide consensus that this contaminated culture can no longer be accepted and needs to change this article examines the ills of the uk financial market more specifically the cultural contamination problem which was uncovered by the 2008 financial crisis in order to explore its genesis and the suitable solutions for it in this regard the article analyses the ethical finance sector from theoretical and practical perspectives in order to assess its role in addressing the cultural contamination problem of the uk financial market

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

repeated games with frequent signals we study repeated games with frequent actions and frequent imperfect public signals where the signals are the aggregate of many discrete events such as sales or tasks the high frequency limit of the equilibrium set depends on both the probability law governing the discrete events and on how many events are aggregated into a single signal when the underlying events have a binomial distribution the limit equilibria correspond to the equilibria of the associated continuous time game with diffusion signals but other event processes that aggregate to a diffusion limit can have a different set of limit equilibria thus the continuous time game need not be a good approximation of the high frequency limit whenever the underlying events have three or more possible values

efficiency results in n player games with imperfect private monitoring abstract we demonstrate that efficiency is achievable in a certain class of n player repeated games with private almost perfect monitoring our equilibrium requires only one period memory and can be implemented by two state automata furthermore we show that this efficiency result holds with any degree of accuracy of monitoring if private signals are hemiindependent whereas most existing research focuses on two player cases or only a special example of n player games our results are applicable to a wide range of n player games of economic relevance such as trading goods games and price setting oligopolies

some evidence on the effect of the separation of spending and taxing decisions it is often argued that separation of public spending and taxing decisions engenders in the voter overoptimistic hopes that someone else will bear the cost of public services thereby inducing an increase in the size of government but are perceived tax prices systematically and persistently reduced by separation although in stock markets all agents expectations may be unbiased they may or may not be unbiased in political markets this paper analyzes the separation created in federal states when the central government finances local expenditures evidence from a dynamic decisive voter model is presented that indicates that the separation introduced by federal grants to canadian provinces did in fact reduce the perceived tax price of provincial public services and raise provincial expenditures the results suggest also that the effect of separation diminished over time

stakeholders matter how social enterprises address mission drift this study explores social enterprises strategies for addressing mission drift relying on an inductive comparative case study of two italian social enterprises we show how stakeholder engagement combined with social accounting can successfully support a social venture to re balance its positioning between wealth generation and social value creation indeed stakeholder engagement helps the internal actors of a social enterprise to rationalize and embody pro social values previously abandoned while social accounting reinforces this embodiment process by showing the reintroduced social commitment of the social enterprise to external audiences conversely strategies focused only on social accounting and without significant engagement of external stakeholders prove to be unsuccessful in counterbalancing mission drift because they fail to activate the necessary process of internal re introduction and operationalization of pro social values and objectives

optimal collusion under imperfect monitoring in multimarket contact abstract we investigate optimal collusion in repeated multimarket contact under imperfect public monitoring where two firms operate in m markets and in each market each firm s decision and public signals are binary we show that in an optimal pure strategy strongly symmetric perfect public equilibrium the size of efficiency loss is equal to that in the market with the most tempting deviation under single market contact furthermore we show a sufficient condition under which the symmetric equilibrium is optimal for joint payoff maximization among any perfect public equilibrium

assessing the accountability of government sponsored enterprises and quangos government sponsored enterprises gses and quasi autonomous non governmental organizations quangos comprise a powerful organizational sector that has been criticized for its lack of accountability to governments and their citizens these organizations are established to serve the public as a whole by targeting the needs of particular groups or fulfilling specific functions often they use practices adopted from the business sector and sometimes they enter the marketplace as profit making enterprises in light of the contribution of gse fannie mae to the 2008 world economic crisis the impact of this sector on effective democratic government bears further examination in this article i present a systems model that suggests how researchers might comprehensively assess the accountability of organizations in this sector here termed the gray sector with respect to their government missions i focus on four systems dimensions mission organizational design organizational outcomes and the information feedback process organizational design and the nature of the sector population are cited as emerging issues of particular importance

the causal relation between federal expenditures and receipts federal expenditures have consistently exceeded federal revenues since 1970 in fact the federal government has seen a surplus in only five years since 1950 the symptoms of such fiscal imbalance are of course budget deficits while budget deficits are nothing new in u s history the recent and projected size of the deficit during peacetime nonrecessionary years has been the cause of much concern to academics the news media and politicians this preoccupation with federal deficits has produced a variety of policy proposals to deal with them

money and the commons an investigation of complementary currencies and their ethical implications the commons is a concept increasingly used with the promise of creating new collective wealth in the aftermath of the economic and financial crises finance and money have been criticized and redesigned to serve the collective interest in this article we analyze three types of complementary currency cc systems community currencies inter enterprise currencies and cryptocurrencies we investigate whether these systems can be considered as commons to address this question we use two main theoretical frameworks that are usually separate the new commons in organization studies and the common good in business ethics our findings show that these monetary systems and organizations may be considered as commons under the common good framework since they promote the common interest by creating new communities nevertheless according to the new commons framework only systems relying on collective action and self management can be said to form commons this allows us to suggest two new categories of commons the social commons which fit into both the new commons and the common good frameworks and the commercial commons which fit the common good but not the new commons framework this research advances a new conceptualization of the commons and of the ethical implications of ccs

on interdependent supergames multimarket contact concavity and collusion abstract following bernheim and whinston 1990 this paper addresses the effects of multimarket contact on firms ability to collude real world imperfections tend to make firms objective function strictly concave and market supergames interdependent firms payoffs in each market depend on how they are doing in others then multimarket contact always facilitates collusion it may even make collusion sustainable in all markets when otherwise it would not be sustainable in any the effects of conglomeration are discussed multigame contact is shown to facilitate cooperation in supergames other than oligopolies as long as agents objective function is submodular in material payoffs journal of economic literature classification numbers c72 d43 l13 l21

corporate governance and codes of ethics as a result of recent corporate scandals several rules have focused on the role played by boards of directors on the planning and monitoring of corporate codes of ethics in theory outside directors are in a better position than insiders to protect and further the interests of all stakeholders because of their experience and their sense of moral and legal obligations female directors also tend to be more sensitive to ethics according to several past studies which explain this affirmation by early gender socialization the fact that women are thought to place a greater emphasis on harmonious relations and the fact that men and women use different ethical frameworks in their judgments the goal of this paper is to determine the influence of these characteristics of the board in terms of promoting and hindering the creation of a code of ethics our findings show that a greater number of female directors does not necessarily lead to more ethical companies moreover within europe as a continent board ownership leads to an entrenchment of upper level management generating a divergence between the ethical interests of owners and managers in light of this situation the presence of independent directors is necessary to reduce such conflicts

virtuous professionalism in accountants to avoid fraud and to restore financial reporting over the past decade a number of accounting and financial reporting frauds have led to lost stock wealth destroyed public trust and a worldwide recession that called for necessary reform regulatory responses and systemic reforms quickly followed and we show that while necessary these reforms are insufficient the purpose of this paper is to forward virtuous professionalism as a necessary path toward restoring financial reporting systems we take the position of external observer and analyze the accounting profession over time to assess what has transpired within our financial reporting systems our analysis reveals that the combined influence of commercialism and regulatory response has led to a systemic decline in accounting s professional ideals and as a result an erosion of public trust we then propose virtuous professionalism as a necessary process for restoring financial reporting systems based on sociological professional and philosophical theories we argue that virtuous professionalism is necessary for restoring the public servant identity of the accounting professional we conclude that efforts to restore financial reporting systems should begin with reforms that restore professional identity shaped by virtues

a credit score system for socially responsible lending ethical banking microfinance institutions or certain credit cooperatives among others grant socially responsible loans this paper presents a credit score system for them the model evaluates social and financial aspects of the borrower the financial aspects are evaluated under the conventional banking framework by analysing accounting statements and financial projections the social aspects try to quantify the loan impact on the achievement of millennium development goals such as employment education environment health or community impact the social credit score model should incorporate the lender s know how and should also be coherent with its mission this is done using multi criteria decision making mcdm the paper illustrates a real case a loan application by a social entrepreneur presented to a socially responsible lender the decision support system not only produces a score but also reveals strengths and weaknesses of the application

economy of mutuality merging financial and social sustainability the article posits the concept of economy of mutuality as an intellectual mediation space for shifts in emphasis between market and social structures within economic theory and practice economy of mutuality it is contended provides an alternative frame of reference to the dichotomy of market economy and social economy for inquiry about what business is for and what values it presupposes and creates the article centers around the objective of gaining a broadened understanding of business so as to include not just market economy but social enterprise and social economy in pursuit of this objective a range of various archetypes of business enterprise are considered in light of higher ends of economic life the highest telos of business encompassing all such archetypes it is argued is founded on reciprocity and integral human development the article concludes that compared to market economy per se economy of mutuality provides a better conceptual framework for business in undertaking the challenges of sustainability

multimarket contact in continuous time games abstract this paper investigates whether multimarket contact is effective in increasing the value of collusion we show that for any discount rate the set of equilibrium payoffs average per market expands through multimarket contact in continuous time games

a review of theories of the firm and their contributions to corporate sustainability corporate sustainability has arisen as an alternative to traditional short term profit oriented ap proaches to managing the firm by holistically balancing economic environmental and social issues in the present generation and for future ones although a number of theories of the firm have been pro posed within recent decades their application to corporate sustainability has been limited this paper presents an overview of the most widely used theories of the firm such as the stockholder theory the aggregate theory the contractual theory the resource based view and the stakeholder theory and analyses their contributions to corporate sustainability from an interpretative perspective the discus sion highlights the point that each of the theories on its own is limited in addressing sustainability s four dimensions i e the economic environmental social and time nonetheless each theory or group of theories has a particular perspective or principles that can contribute to one or more of the four dimensions the authors of this paper propose a sustainability oriented theory of the firm which is built upon elements of those theories as they relate to corporate sustainability this new theory can be useful in providing the firm s leaders and all of its stakeholders with a more complete vision of its ob ligations opportunities relations and processes that the firm should address as it engages in helping to make societies become more equitable and sustainable in the short and long terms

evaluating the performance of us credit unions credit unions are small cooperative not for profit institutions which distinguishes them from other financial intermediaries in this study we conduct a performance evaluation of credit unions the criteria respect the unique organizational and institutional features of credit unions without losing sight of the fact that they must compete with other financial intermediaries we use nonparametric nonstochastic techniques to measure performance and we use parametric stochastic techniques to attribute performance variation to features of credit unions and their operating environment our sample consists of two thirds of all active credit unions in 1990

multimarket contact imperfect monitoring and implicit collusion abstract this paper presents a theoretical foundation to the possibility that multimarket contact enhances firms ability to sustain implicit collusion when firms operate in a single market and cannot perfectly monitor their opponents choices it is impossible to achieve efficiency even if these firms have a long term strategic relationship we show that when firms encounter each other in a number of distinct markets and the extent of this market contact is large efficiency can be approximately sustained by a perfect equilibrium this efficiency with imperfect monitoring holds under almost the same condition on the discount factor as with perfect monitoring journal of economic literature classification numbers c70 c72 c73 d43 l11 l22 l41

vive la difference social banks and reciprocity in the credit market social banks are financial intermediaries paying attention to non economic i e social ethical and environmental criteria to investigate the behavior of social banks on the credit market this paper proposes both theory and empirics our theoretical model rationalizes the idea that reciprocity can generate better repayment performances based on a unique hand collected dataset released by a french social bank our empirical results are twofold first we show that the bank charges below market interest rates for social projects second regardless of their creditworthiness motivated borrowers respond to advantageous credit terms by significantly lowering their probability of default we interpret this outcome as the first evidence of reciprocity in the credit market

repeated partnership games with imperfect monitoring and no discounting in a partnership game each player s utility depends on the other players actions through a commonly observed consequence e g output profit price which is itself a function of the players actions and an exogenous stochastic environment if a partnership game is repeated infinitely and each player s payoff in the infinite game supergame is the long run average of his expected one period utilities then efficient combinations of one period actions can be sustained as nash equilibria of the supergame even if the players cannot observe other players actions or information but can only observe the resulting consequences

excess bias and the nature of budget growth abstract to examine the hypothesis that budget growth has been excessive the concept of correct budget size must first be defined this proves a difficult task for the level of public services but especially so regarding redistribution and transfer payments next potential sources of bias are explored including distortions in voting bureaucracy and political leadership analysis shows that bias may be in either direction making for deficient as well as excess budgets institutional reform therefore should not prejudge the outcome by imposing limitations the goal should be to improve the budget process however this may affect budget size

how well have social economy financial institutions performed during the crisis period exploring financial and social efficiency in spanish credit unions as social economy financial institutions credit unions have traditionally been considered less efficient than traditional banking entities however like banks and savings banks they have to be as efficient and competitive as possible to survive in today s business environment especially at times of crisis to date there have been very few studies on their efficiency and practically none for the crisis period moreover almost all the existing studies assess only financial efficiency without considering their social function this study examines the levels of both financial and social efficiency in spanish credit unions as well as their main determinants during the recent crisis we apply the two stage double bootstrap data envelopment analysis dea methodology based on panel data corresponding to all the credit unions active in spain between 2008 and 2013 the empirical results indicate that financial and social efficiency achieved an acceptable level although on average the former was slightly greater than the latter we also find that both age and merger and acquisition activity were positively influential on the financial efficiency of credit unions but had a significant negative effect on their social efficiency moreover the regional location of such entities and the financial crisis were also crucial determinants of both types of efficiency our findings are therefore useful for all the stakeholders of credit unions to know if these entities have been efficient according to a double bottom line accounting in the crisis period and hence to maintain successful social management that is compatible with satisfactory financial efficiency

impossibility of collusion under imperfect monitoring with flexible production we show that it is impossible to achieve collusion in a duopoly when 1 goods are homogenous and firms compete in quantities 2 new imperfect information arrives continuously without sudden events and 3 firms are able to respond to this new information quickly the result holds even if we allow for asymmetric equilibria or monetary transfers the intuition is that the flexibility to respond to new information quickly unravels any collusive scheme and that signals about the aggregate behavior only cannot be used effectively to provide individual incentives via transfers our result applies both to a simple stationary model and a more complicated one with prices following a mean reverting markov process

fiscal decentralization and government size numerous studies have attempted to model the possible factors contributing to universal growth in public sectors this paper analyzes one device that appears capable of controlling some of that growth fiscal decentralization the results reported here also support the use of monopoly government assumptions in models of public policy

reconsidering the common good in a business context in our contemporary post modern context it has become increasingly awkward to talk about a good that is shared by all this is particularly true in the context of mammoth multi national corporations operating in global markets nevertheless it is precisely some of these same enormous aggrandizing forces that have given rise to recent corporate scandals these in turn raise questions about ethical systems that are focused too myopically on self interest or the interest of specific groups locations or cultures the obvious traditional alternative to moral bellybutton gazing is the common good which challenges the modern business enterprise to realize non instrumental values that can only be attained in our life together the common good dictates that leadership should be judged first of all according to moral criteria rather than professional competence it helps correct the distorted prioritization of the maximization of profit in every business decision recognizing that businesses have a multitude of rights and responsibilities and the common good reminds us that the first of these is not always profit making

on the limitations of government borrowing a framework for empiricaltesting this paper seeks to distinguish empirically between two views on the limitations of government borrowing according to one view nothing precludes the government from running a permanent budget deficit paying interest due on the growing debt load simply by issuing new debt an alternative perspective holds that creditors would be unwilling to purchase government debt unless the government made a credible commitment to balance its budget in present value terms we show that distinguishing between these possibilities is mathematically equivalent to testing whether a continuing currency inflation might be fueled by speculation alone or is instead driven solely by economic fundamentals empirical tests which have been developed for this economic question lead us to conclude that postwar u s deficits are largely consistent with the proposition that the government budget must be balanced in present value terms this abstract was borrowed from another version of this item

the folk theorem with imperfect public information the authors study repeated games in which players observe a public outcome that imperfectly signals the actions played they provide conditions guaranteeing that any feasible individually rational payoff vector of the stage game can arise as a perfect equilibrium of the repeated game with sufficiently little discounting the central condition requires that there exist action profiles with the property that for any two players no two deviations one by either player give rise to the same probability distribution over public outcomes the results apply to principal agent partnership oligopoly and mechanism design models and to one shot games with transferable utilities copyright 1994 by the econometric society

social enterprises and the performance advantages of a vincentian marketing orientation this study focuses on the managerial issue of should social enterprises ses become more marketing oriented it adapts the kohli et al j mark res 30 467 477 1993 markor marketing orientation scale to measure the adoption of marketing by ses the items capture vincentian based values to leverage business in service to the poor as a measure of a vincentian marketing orientation vmo a vmo is an organisational wide value driven philosophy of management that focuses a se on meeting its objectives by adopting a more marketing orientated approach to serve the needy and poor in a just and sustainable manner ses that exhibit a vmo seek to understand and respond to both the needs of their beneficiaries and stakeholders they are constantly generating disseminating and responding to environmental beneficiary and stakeholder information and develop their business propositions to more effectively and efficiently meet the needs of the poor while guided by a philosophy of leveraging business for social good this study of ses in australia found that a vmo is strongly and positively correlated with social economic and environmental performance these findings suggest that ses may benefit by leveraging marketing capabilities to better serve their beneficiaries and stakeholders

the future of stakeholder management theory a temporal perspective we propose adding a temporal dimension to stakeholder management theory and assess the implications thereof for firm level competitive advantage we argue that a firm s competitive advantage fundamentally depends on its capacity for stakeholder management related transformational adaptation over time our new temporal stakeholder management approach builds upon insights from both the resource based view rbv in strategic management and institutional theory stakeholder agendas and their relative salience to the firm evolve over time a phenomenon well understood in the literature and requiring what we call level 1 adaptation however the dominant direction of stakeholder pressures can also change namely from supporting resource heterogeneity at the firm level to fostering industry homogeneity and vice versa when dominant stakeholder pressures shift from supporting heterogeneity towards stimulating homogeneity in industry the firm must engage in level 2 or transformational adaptation stakeholders typically provide valuable resources to the firm in an early stage without these resources which foster heterogeneity in line with rbv thinking the firm would not exist at a later stage stakeholders also contribute to inter firm homogeneity via isomorphism pressures in line with institutional theory thinking adding a temporal dimension to stakeholder management theory has far reaching implications for this theory s practical relevance to senior level management in business

the growth of government in the united states an economic historian s perspective abstract this paper first outlines the salient features of the growth of government in american history secondly it offers a neoclassical explanation of that history in which increasing specialization and division of labor brought on by the scientific technological revolution of the nineteenth century drastically altered the demand for and supply of government finally it argues that institutions matter and describes the way the particular structure of governments was important in the timing and pace of its growth

deal structuring in philanthropic venture capital investments financing instrument valuation and covenants philanthropic venture capital phvc is a financing option available for social enterprises that like traditional venture capital provides capital and value added services to portfolio organizations differently from venture capital phvc has an ethical dimension as it aims at maximizing the social return on the investment this article examines the deal structuring phase of phvc investments in terms of instrument used from equity to grant valuation and covenants included in the contractual agreement by content analyzing a set of semi structured interviews and thereafter surveying the entire population of phvc funds that are active in europe and in the united states findings indicate that the non distribution constraint holding for non profit social enterprises is an effective tool to align the interests of both investor and investee this makes the investor behaving as a steward rather than as a principal conversely while backing non profit social ventures philanthropic venture capitalists structure their deal similarly as traditional venture capital as the absence of the non distribution constraint makes such investments subject to moral hazard risk both in terms of perks and stealing and social impact focus

the effect of national corporate responsibility environment on japanese foreign direct investment we examine the relationship between japanese foreign direct investment fdi and the national corporate responsibility ncr environment in host countries using corporate social responsibility and international business theories based on data from the japanese government s ministry of finance accountability and other sources we find that the level of ncr has a positive relationship with fdi inflow for developing countries the relationship for developed countries is negative but not statistically significant the underlying host country development stage moderates the relationship the results can help deepen understanding of fdi behaviors and have practical implications for host countries in terms of attracting fdi

on the theory of repeated games with private information part ii revelation through communication abstract we consider repeated games with private information discounting and communication similarly to abreu et al 1986 1987 we characterize supergame equilibrium allocations with truthful revelation in the two player case efficiency cannot be attained with supergame equilibria with truthful revelation

optimal cartel equilibria with imperfect monitoring abstract there exist optimal symmetric equilibria in the green porter model 4 8 having an elementary intertemporal structure such an equilibrium is described entirely by two subsets of price space and two quantities the only production levels used by firms in any contingency the central technique employed in the analysis is the reduction of the repeated game to a family of static games

optimal contracting with subjective evaluation this paper extends the standard principal agent model to allow for subjective evaluation the optimal contract results in more compressed pay relative to the case with verifiable performance measures moreover discrimination against an individual implies lower pay and performance suggesting that the extent of discrimination as measured after controlling for performance may underestimate the level of true discrimination finally the optimal contract entails the use of bonus pay rather than the threat of dismissal hence neither efficiency wages nor the right to dismiss an employee are necessary ingredients for an optimal incentive contract

how to get the snowball rolling and extend the franchise voting on the great reform act of 1832 this paper suggests a new approach to analyzing the causes of franchise extension based on a new dataset it provides a detailed econometric study of the great reform act of 1832 in the united kingdom the analysis yields four main results first modernization theory receives limited support second the reform enjoyed some measure of popular support third the threat of revolution had an asymmetric impact on the voting behavior of the pro reform whigs and the anti reform tories while the threat might have convinced reluctant reformers among the whig politicians and among their patrons to support the bill it seems to have hardened the resistance to reform among the tories fourth ideology played a critical role nevertheless it also appears that self interest and political expedience explained the votes of many members of parliament

toward a common good theory of the firm the tasubinsa case tasubinsa is a special employment and occupational center constituted in accordance with spanish law where 90 of the workers have mental sensorial or physical impairments of at least 30 its positive experience of more than 15 years provides entirely different responses from mainstream neoclassical theory transaction cost theory agency theory and shareholder theory to basic questions such as what is a firm what is its purpose who owns a firm and what do a firm s owners seek the article discusses how these different premises give rise to a distinctive corporate culture centered on the handicapped person

interest groups and the size of government the results of the previous section estimates of a three equation model from 23 observations must obviously be regarded as tentative the consistent positive relationship between number of interest groups and size of government observed with changing sets of included independent variables changing samples of nations and treating the number of interest groups as either exogenous or codetermined does imply rather unequivocally that interest groups are able to influence public policies in such a manner as to lead to increased government size beyond helping to reinforce this conclusion the results of the previous section should be regarded as first steps in the development of a model of the polity that can explain participation in the political process by interest groups and citizens as well as the size of government

corporate sustainability toward a theoretical integration of catholic social teaching and the natural resource based view of the firm even though management scholars have offered several views on the process of corporate sustainability these efforts have focused mainly on the technical aspects of sustainability while omitting the fundamental role played by individual moral competences therefore previous work offers an incomplete and somewhat reductionist view of corporate sustainability in this article we develop a holistic framework of corporate sustainability in which both the moral and technical aspects of sustainability are considered we do so by integrating the ethical normative perspective of the catholic social teaching cst with the competitive view of the natural resource based view this framework highlights the importance of cst principles and ideas in developing executive moral competences such as moral sensitivity and awareness and moral cognition and motivation moral competences in turn influence the organizational selection of environmental strategies giving leaders the intrinsic motivation to promote both a longer term stance on corporate sustainability efforts and a relentless search for greener business models such strategies move the firm closer towards achieving environmental sustainability hence by bridging the individual normative ethical with the organizational implementational levels of corporate sustainability our framework provides a more realistic coherent and complete perspective on the complex process of achieving corporate sustainability

expenditures and receipts testing for causality in state and local government finances the results of our tests indicate similarities between the expenditure tax receipt relations of state governments to those previously reported for the federal government in manage and marlow 1986 the results reported here indicate support for the hypothesis that tax receipts cause expenditures at the state level of government for tests utilizing symmetric lag structures ranging from three to five years state expenditures appear to follow state tax receipts for the shortest lag length 2 2 the determination of bidirectional causality does not make us reject the hypothesis that higher spending levels result from higher revenue levels rather the causality appears to be in both directions for the shortest lag length

income inequality size of government and tax progressivity a positive theory abstract i investigate the relationship between income inequality and the composition of public spending in redistributive policies i extend the meltzer richard model of voting over redistribution allowing voters to choose not only the amount of a uniform lump sum transfer but also the level of provision of a public good the governmental budget is balanced thus these two choices determine the tax rate on labor income the multidimensionality of the policy space implies that there is no condorcet winner i adopt a citizen candidate model of electoral competition to tackle this problem i show that the progressivity of the tax system is increasing in the mean to median income ratio while the size of the government need not be this means that higher income inequality implies a more progressive tax system but in contrast with the traditional analysis it may also result in a smaller size of government such results are consistent with the most recent findings in the empirical literature

private equity and the public good the dominance of agency theory can reduce our collective scope to analyse private equity in all its diversity and depth we contribute to theorisation of private equity by developing a contrasting perspective that draws on a rich tradition of virtue ethics in doing so we juxtapose private equity with public good to develop points of rhetorical and analytical contrast we develop a typology differentiating various forms of private equity and focus on the take private form these takeovers are where private equity funds are used to buy all a firm s publicly listed shares take private deals reduce reporting requirements and lessen the amount of public scrutiny a firm comes under they allow greater control of a firm s assets and resources but also have effects in terms of the wider social fabric the public good and virtue ethics offer an alternative basis for theorisation of these deals this provides a needed contrast to accounts of private equity based on agency theory

perfect public equilibrium when players are patient we provide a characterization of the limit set of perfect public equilibrium payoffs of repeated games with imperfect public monitoring as the discount factor goes to one our result covers general stage games including those that fail a full dimensionality condition that had been imposed in past work it also provides a characterization of the limit set when the strategies are restricted in a way that endogenously makes the full dimensionality condition fail as in the strongly symmetric equilibrium studied by abreu abreu d 1986 extremal equilibria of oligopolistic supergames j econ theory 39 191 228 and abreu et al abreu d pearce d stacchetti e 1986 optimal cartel equilibria with imperfect monitoring j econ theory 39 251 269 finally we use our characterization to give a sufficient condition for the exact achievability of first best outcomes equilibria of this type for which all continuation payoffs lie on the pareto frontier have a strong renegotiation proofness property regardless of the history players can never unanimously prefer another equilibrium

the new economy ethical issues the new economy is a technological revolution involving the information and communication technologies and which affects almost all aspects of the economy business and our personal lives the problems it raises for businesses are not radically new and even less so from an ethical viewpoint however they deserve particular attention especially now in the first years of the 21st century when we are feeling the full impact of the changes brought about by this technological revolution in this article i will try to draw a map of the main positive and negative ethical challenges raised by the new economy concentrating on its three basic features 1 a knowledge and information based technological change 2 which is taking place in real time on a planetary scale globalization and 3 which entails a new flexible network based business organization

controlling leviathan through tax reduction our paper seeks the strategy that allows the greatest ability to reduce public sector size within a political environment that does not want us to directly set limits on public sector size tax reduction through its quid pro quo effect offers high tangibility to taxpayers and may raise political power of groups that seek both tax reduction and greater opposition to lobbies that seek spending increases for their narrowly defined interests moreover as manage and marlow 1986 argues since the political response to balanced budget rules is likely to raise taxes this political bias of tax hikes suggests that balanced budget rules are offered as a means of changing the funding mix and not the actual budget constraint of government

a few good companies rethinking firms responsibilities toward common pool resources while a significant body of literature has highlighted the moral obligations of companies regarding the sustainable use of common pool resources business activities that contribute to the sustenance of common pool resources remain embryonic studies in this area have largely focused on environmental stimuli rather than on the complex motivational structures that drive or hinder businesses contributions to common pool resources we explore the different motives and behaviors of businesses and their contributions to common pool resources and propose four roles by which companies motives and behaviors toward common pool resources can be categorized namely free riders followers believers and altruists we shift the focus from moral reasoning to platt s am psychol 28 8 641 651 1973 notion of social trapping and his ways out as platt s ways out include propositions that address not only environmental stimuli but also companies motives both types of propositions are important for businesses to be able to respond rapidly to the scarcity of certain common pool resources and to use and maintain common pool resources in a sustainable way based on our categorization and platt s typology of social traps and ways out we propose a theoretical framework by which companies and other stakeholders are provided with a differentiating perspective that allows for propositions addressing the complex nature of motivational structures and common pool resources our framework helps business leaders institutions and policy makers decide on actions that can contribute to the sustainability of common pool resources and that differ from actions that solely serve organizational self interests

a study of bank efficiency taking into account risk preferences abstract i use the stochastic cost frontier approach to investigate efficiency of banks operating in the third federal reserve district accounting for the quality and riskiness of bank output in addition to the mean and mode of the conditional distribution of the one sided error term i calculate confidence intervals for the inefficiency measures based on the conditional distribution the results indicate that third district banks are operating at cost efficient output levels and product mixes but are not efficiently using their inputs the second part of the article relates the inefficiency measures to several correlates

a cultural theory of expenditure growth and un balanced budgets abstract why does public spending grow because the literature tells us nations are rich because they are poor because their economies are open because their economies are closed because there is consensus because there is conflict if all roads lead to rome i suggest that may be because it is the destination not the detours that matter so i ask a different question which political cultures shared values legitimating social practices would reject ever greater governmental growth and which ones would perpetuate it my hypothesis is that the size of government in any given society is a function consequence if you prefer of its combination of political cultures the theory also explains the tendencies of political regimes to balance or unbalance their budgets

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

ownership and technical efficiency of microfinance institutions empirical evidence from latin america by using stochastic frontier analysis this article examines the technical efficiency of different types of microfinance institutions in latin america in particular it tests whether differences in technical efficiency both intra and interfirm can be explained by differences in ownership with a focus on non governmental organizations cooperatives and credit unions non bank financial intermediaries and banks the data set contains 1681 observations from a panel of 315 institutions operating in 18 latin american countries the results show that non governmental organizations and cooperatives have much lower interfirm and intrafirm technical efficiencies than non bank financial intermediaries and banks which indicates the importance of ownership type for technical efficiency

the stakeholder theory and the common good the theory of the social responsibility of the firm oscillates between two extremes one that reduces the firm s responsibility to the obtainment of the greatest possible profit for its shareholders and another that extends the firm s responsibility to include a wide range of actors with an interest or stake in the firm the stakeholder theory of the social responsibility of business is more appealing from an ethical point of view and yet it lacks a solid foundation that would be acceptable to a variety of schools of thought in this paper i argue that the stakeholder theory could be founded on the concept of the common good first i explain the foundations of the theory of the common good the concept itself how it relates to the individual good and its role in the firm following that i explain how the theory of the common good could be applied to the stakeholder theory finally i draw some conclusions

profit and more catholic social teaching and the purpose of the firm the empirical findings in collins and porras study of visionary companies built to last and the normative claims about the purpose of the business firm in centesimus annus are found to be complementary in understanding the purpose of the business firm a summary of the methodology and findings of built to lastand a short overview of catholic social teaching are provided it is shown that centesimus annus claim that the purpose of the firm is broader than just profit is consistent with collins and porras empirical finding that firms which set a broader objective tend to be more successful than those which pursue only the maximization of profits it is noted however that a related finding in collins and porras namely that the content of the firm s objective is not as important as internalizing some objective beyond just profit maximization can lead to ethical myopia two examples are provided of this the walt disney company and philip morris centesimus annus offers a way to expose such myopia by providing guidance as to what the purpose of the firm is and therefore as to what kinds of objectives are appropriate to the firm

ideology and the size of us state government this paper theorizes that the impact of ideology on the size of us state governments increases with state income this idea is tested using state level ideology data derived from the voting behavior of state congressional representatives empirically the interaction of ideology and mean income is a key determinant of state government size at 1960s levels of income the impact of ideology is negligible at 1997 levels of income a one standard deviation move towards the left of the ideology spectrum increases state government size by about half a standard deviation estimated income elasticities differentiated by state and time are found to be increasing with ideology and diminishing with income as predicted by the theory

repeated games with private monitoring two players we investigate two player infinitely repeated games where the discount factor is less than but close to unity monitoring is private and players cannot communicate we require no condition concerning the accuracy of players monitoring technology we show the folk theorem for the prisoners dilemma with conditional independence we also investigate more general games where players private signals are correlated only through an unobservable macro shock we show that efficiency is sustainable for generic private signal structures when the size of the set of private signals is sufficiently large finally we show that cartel collusion is sustainable in price setting duopoly

an example of a repeated partnership game with discounting and with uniformly inefficient equilibria in this note we present an example of a repeated partnership game with imperfect monitoring in which all supergame equilibria with positive discount rates are bounded away from full efficiency uniformly in the discount rate provided the latter is strictly positive on the other hand if the players do not discount the future then every efficient one period payoff vector that dominates the one period equilibrium payoff vector can be attained by an equilibrium of the repeated game thus the correspondence that maps the players discount rate into the corresponding set of repeated game equilibrium payoff vectors is discontinuous at the point at which the discount rate is zero

income distribution and tax structure empirical test of the meltzer richard hypothesis abstract the meltzer richard hypothesis that more unequal income distribution will create a majority for more redistribution has generated much research but little empirical support the empirical literature has concentrated on cross country studies and the size of the public sector and the results broadly do not indicate more redistribution with more inequality this analysis suggests that the hypothesis should be investigated in a more homogenous setting with comparable institutions and with an explicit decision about redistribution here tax structure new data on poll tax and property tax in decentralized government in norway are exploited we show how the multi dimensional decision can be analyzed as majority rule assuming intermediate preferences in the econometric analysis instruments are used to account for endogeneity of income level and income distribution the estimated model supports the understanding that more unequal income distribution implies a shift in the tax burden from poll tax to property taxes and thereby gives more redistribution

multimarket contact competition and pricing in banking abstract in this paper we assess the impact of multimarket contact of banks on their market power by means of a simultaneous equation model in which the divergence of price from marginal cost is a function of multimarket linkages the model is estimated using aggregate data from the italian regions for the years 1997 2009 our results show that multimarket contact is positively and significantly correlated to the market power index and is also connected to both home and non home market concentration the evidence is robust to changes in model specification and multimarket contact measures and supports the idea that firms which have a greater amount of contact are more likely to collude

the effect of decisions under uncertainty on imperfect monitoring games abstract the study of repeated games with imperfect public information began with abreu d pearce d stacchetti e 1986 optimal cartel equilibria with imperfect monitoring journal of economic theory 39 251 269 using dynamic decomposition and was settled in fudenberg d levine d maskin e 1994 the folk theorem with imperfect public information econometrica 62 997 1039 however we suggest that if the effect of uncertainty and irreversibility are considered when punishment is exercised the set of perfect public equilibria and their payoffs would change
