characterization of a class of moral hazard adverse selection games abstract studying a principal agent game in which the agent alone observes the state of the world and reports it but the moral hazard is not reducible shows that if the principal uses all signals then no solution exists i e there is no contract that elicits truth telling and motivates the agent to exert effort when the principal does not use signals on the state of the world that seem irrelevant a solution exists in which some of the ex post signals on outcome are not used even though they obey the informativeness condition of holmstrom bell journal of economics 1979 10 74 91

a bargaining approach to profit sharing in joint ventures profit sharing arrangements in joint ventures are analyzed as a bayesian bargaining game between two parents with incomplete information about each other s cost function for inputs provided using the mathematics of mechanism design this article explores the sensitivity of the bargaining agreement to the timing of private information about costs a condition on demand and costs is derived under which the balanced budget constraint does not preclude the joint venture from achieving an ex post efficient level of production the proposed mechanism is then extended to the second best environment under the criteria of 1 ex ante optimality and 2 r b myerson s axiomatic neutral bargaining solution the direct revelation mechanisms are interpreted as corresponding indirect transfer pricing mechanisms a major result is that in all cases the outcome calls for equal allocation of realized joint venture net profit copyright 1989 by the university of chicago

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

optimal redistribution and monitoring of labor supply this paper extends the mirrlees 1971 model of optimal non linear income taxation with a monitoring technology that allows the government to verify labor supply at a positive but non infinite cost we analyze the joint determination of the non linear monitoring and tax schedules and the conditions under which these can be implemented monitoring of labor supply reduces the distortions created by income taxation and raises optimal marginal tax rates possibly above 100 the optimal intensity of monitoring increases with the marginal tax rate and the labor supply elasticity our simulations demonstrate that monitoring strongly alleviates the trade off between equity and efficiency welfare gains of monitoring are around 2 8 of total output the optimal intensity of monitoring follows a u shaped pattern similar to that of optimal marginal tax rates our paper can explain why large welfare states optimally rely on work dependent tax credits active labor market policies benefit sanctions and work bonuses in welfare programs

the role of options in the resolution of agency problems a comment the aim of the contracting literature in economics is to explain observed contractual arrangements or organizations as minimizing the costs of incentive conflicts in the agency cost literature of financial economics the contractual arrangement at issue is the mix of securities held by inside management of a firm and outside suppliers of capital the ownership structure of the firm in jensen and meckling s 8 terminology in explaining the ownership structure of a corporation jensen and meckling focus on two sources of agency or incentiveconflict costs a the manager s tendency to consume excessive perquisites and b the manager s tendency to invest in prospects of high risk so as to effect an ex post transfer from bondholders to stockholders a recent article in this journal by haugen and senbet 61 examines the role of stock options in resolving these agency problems and claims to show in particular that a call option in the insider portfolio can eliminate the first type of agency costs this article re examines the role of options in the resolution of agency problems we argue in section i that options cannot eliminate the agency problem of excessive perquisite consumption contrary to haugen and senbet the essential point is that unless outside financing can be provided entirely by riskless debt then outsiders must have a residual claim on the net income of the firm in some states of the world outsiders therefore share in the costs of increased perquisite consumption whatever the ownership structure of the firm this negative externality means that excessive perquisite consumption is inevitable the question remains do call options nonetheless have a role in the mitigation of agency costs an insider portfolio consisting only of equity leaves the manager with the same proportion of residual claim in each state of the world we show using a formal principal agent model that the efficient insider s share of profits is relatively high in favorable high profit states of the world insider call options arise as means of transferring residual claim to the manager in favorable states of the world relative to low profit states the basic agency model has been solved in substantial generality by holmstrom 7 and others we employ here a more specific model that draws on the techniques developed by green and kahn 4 and that is an extension to continuous states of the finite state model of sappington 12 the extension allows a simple characterization of the optimal contract a characterization that

multi period insurance contracts this paper examines the form of insurance contracts in the presence of asymmetric information about consumers accident probabilities our goal is to understand the adjustment in contract terms as a function of accident histories in a finite horizon model we also compare these adjustments between alternative market structures our principal findings indicate that history dependent insurance contracts serve a useful sorting role individuals who declare themselves low risks to insurance companies face adverse contracturai terms if they subsequently have many accidents these adjustments are strongest in the case of a single insurance seller but are present in the competitive model as well

a revelation scheme for allocating organizational resources abstract efficient resource allocation in a hierarchical organization frequently requires top management to obtain information from division managers but division managers may place personal interests above those of the organization and communicate distorted information designing simple and robust optimal game theoretic revelation schemes is difficult instead of making another attempt at this we analyze a project valuation scheme actually used by several us government agencies under certain environments the scheme encourages managers to truthfully reveal the relative benefits of alternative projects while some aspects of these environments do not have nice mathematical properties we argue that they may well represent better characterizations of the way managers actually view their situation

a study of cartel stability the joint executive committee 1880 1886 this article employs weekly time series data on the joint executive committee railroad cartel from 1880 to 1886 to test empirically the proposition that observed prices reflected switches from collusive to noncooperative behavior an equilibrium model of dynamic oligopoly with asymmetric firms together with explicit functional form assumptions about costs and demand determines the estimating equations and stochastic structure of the econometric model the hypothesis that no switch took place so that price and quantity movements were solely attributable to exogenous shifts in the demand and cost functions is then tested against this alternative and rejected

money as the mechanism of exchange abstract the existence and use of money remained an embarrassing puzzle for monetary analysis we observe over man s history that social groups without generally accepted media of exchange exhibit poor survival characteristics most social groups do not use assets or commodities at random in the execution of exchanges one observes that a small subset of assets is dominantly used in transactions these transaction dominating assets are usually referred to as money the literature contains many suggestive attempts to explain the emergence and role of money the classic writers made passing references in somewhat pictorial language to the extension markets and increasing labor productivity induced by the use of a general medium of exchange this idea has never been systematically developed however karl brunner 1971

balanced bayesian mechanisms in the transferable utility case a number of authors have identified conditions on beliefs that guarantee the existence of bayesian incentive compatible mechanisms with balanced transfers we present a new easy to interpret condition and we show that it is strictly more general than all the other conditions found in the literature we also study conditions guaranteeing the bayesian implementability of all social decision rules with balanced budget mechanisms

imperfect price discrimination and welfare we develop a model in which a monopolist uses differences across consumers in their valuation of time to imperfectly price discriminate though it is customary to analyse price discrimination problems by the calculus of variations after postulating a continuum of types we assume a finite number of types and exploit the geometry and duality of the contract set and the structure of the programming specification we analyse in detail the qualitative properties of the model s solution and show by construction that our results exhaust the implications of the model for equilibrium contract pairs we show that imperfect discrimination is not bounded in welfare terms between perfect discrimination and single price monopoly and that the deadweight loss consumer surplus and output comparisons between single price monopoly and imperfect discrimination are ambiguous

on governing multilateral transactions with bilateral contracts bilateral contracts while neither negotiated nor enforced in an integrated way are nevertheless often interrelated both economically and strategically owing to production or consumption complementarities and to asymmetric information a set of bilateral contracts forms a mechanism with special properties this mechanism forms a contract equilibrium if there is no joint incentive for a supplier and any individual customer unilaterally to alter the terms of their contract if agents preferences are risk neutral in money income and if their private information is independent then there exists a contract equilibrium that implements efficient transactions if in addition preferences are strictly concave and differentiable in goods and services and technologically feasible sets are suitably convex then this equilibrium is essentially unique

the dynamic structure of optimal debt contracts abstract in a two period model of costly state verification the optimal contract is characterized and shown to exist the optimal contract is interpreted as a bond contract the model extends the result of one period models that the verification region must be a left tail interval to a multi period setting conditions are identified for the optimal contract to exhibit features such as call prepayment option coupon payment or sinking fund the optimality of certain bond covenants such as refinancing covenants and dividends covenants is also studied

price stabilization as a bonding mechanism in new equity issues abstract underwriters have an incentive to overstate investor interest in order to persuade some investors to purchase shares at a price in excess of their initial estimate of the fair value we show that this incentive is eliminated when the underwriter commits to secondary market price stabilization destroying the underwriter s incentive to overstate interest reduces the total surplus captured by initial investors in initial public offerings further efficiency gains are associated with penalty bid systems that permit the underwriter to make the stabilization commitment selectively price stabilization can thus be viewed as a bonding mechanism that improves the efficiency of the primary equity market

foreign equity investment restrictions capital flight and shareholder wealth maximization theory and evidence this article provides a theory of foreign equity investment restrictions we consider a model where the demand function for domestic shares differs between domestic and foreign investors because of deadweight costs in holding domestic and foreign securities that depend on the country of residence of investors we show that domestic entrepreneurs maximize firm value by discriminating between domestic and foreign investors the model implies that countries benefitting from capital flight have binding ownership restrictions such that foreign investors pay a higher price for shares than domestic investors the empirical implications of this theory are supported by evidence from switzerland article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

endogenous mergers and collusion in asymmetric market structures recent empirical evidence shows that cartels are often asymmetric while cartel theory suggests that firm symmetry is conducive to collusion including an indivisible cost of cartelization we show that medium asymmetric market structures are more conducive to collusion since they balance the small firms incentives to stay in the cartel against the need to cover the cartel leaders indivisible cartelization cost using an endogenous merger model we also show that forbidding mergers leading to symmetric market structures can induce mergers leading to asymmetric market structures with a higher risk of collusion current antisymmetry merger policy can thus be counterproductive

monitoring of performance in organizational contracting the case of defense procurement this paper contains an agency theoretic analysis of procurement contracts in which the government designs optimal linear contracts for a risk averse supplier in the presence of moral hazard private information and imperfect monitoring optimal contracts deviate from first best risk sharing the direction of the deviation depends on the relative severity of the moral hazard and private information problems and on the precision of the monitor in contrast to the usual result in the moral hazard literature the government may in some cases prefer that the effort of the supplier be taxed choice of the precision of the monitor and the categories of costs covered by the monitor are also studied

contracts and asymmetric information in the theory of the firm abstract this paper extends the coase notation of firms as intermediaries between consumers and input owners to incorporate asymmetric information we show that in some cases it is optimal for consumers to pay a fixed price for a product and to ignore how the firm operates and the profit that it makes if firms have private information that consumers cannot cheaply obtain however we demonstrate that the optimal contract may require constraints on firms internal operations and profits our work provides conditions under which cost plus contracts are optimal and demonstrates when nonprofit firms are the preferred organization structure

planning stochastic shocks and labour contracts of female workers and their welfare implications in this paper we analyse labour contracts for female workers when there are planned shifts or stochastic shocks to their leisure preference which arise as a result of planned or unplanned pregnancy it will be shown that when female workers plan their pregnancy contract firms can induce self selection among workers through a contract that stipulates a wage profile steeper than the spot wage profile so that self selected workers who accept the contract will not quit even though information on shifts in leisure preference is asymmetric first best efficiency can be achieved through self selection when female workers do not plan childbirths however self selection contracts are not possible when the stochastic shocks are realized there will be quits planning is pareto superior to no planning at equilibrium workers will be allocated optimally workers who have low marginal value of home time will join contract firms and make specific investments while those who have high marginal value will seek employment in the walrasian market and make no specific investments some implications of these results are also discussed in the paper

total factor productivity growth in local enterprise partnership regions in britain 1997 2008 harris r and moffat j total factor productivity growth in local enterprise partnership regions in britain 1997 2008 regional studies this paper decomposes aggregate total factor productivity tfp growth in britain for 1997 2008 to show the contribution of different local enterprise partnerships leps as well as manufacturing and services and uk and foreign owned plants within leps these contributions are further decomposed to show the role of productivity growth in continuing plants vis a vis reallocations in output shares the results show that the largest leps in population terms with higher levels of job density a greater reliance on manufacturing more skilled and better qualified workers and a lower turnover of businesses achieved the highest tfp growth this is mostly the result of reallocations of output shares towards high productivity plants

incentive contracting with asymmetric and imperfect precontractual knowledge abstract the pareto optimal contract between principal and risk neutral agent is analyzed for the case in which the agent s information is initially imperfect but better than that of the principal in contrast to the case where precontractual information is symmetric the final contract between principal and agent will not always guarantee an efficient outcome however in contrast to the case where the agent s information is initially perfect the agent may be unable to command rents from his superior information and the outcome will always be efficient the conditions under which efficient or inefficient outcomes are guaranteed differ qualitatively according to whether the random stete of nature follows a continuous or a discrete distribution journal of economic literature classification numbers 022 026 611

adverse selection private information and lowballing in insurance markets recent contributions to the adverse selection literature have focused on a multiperiod competitive environment in this setting a clean distinction arises between the predictions of competing models cooper and hayes extend the model of rothschild and stiglitz to multiple periods the result is a self selecting equilibrium characterized by price highballing or systematically overcharging new business kunreuther and pauly suggest that information asymmetries between competing insurance firms render such price quantity policies infeasible their model results in a pooling equilibrium that is characterized by price lowballing or systematically undercharging new business our evidence is consistent with the kunreuther and pauly model and reveals the persistence of adverse selection in the automobile insurance market copyright 1990 by the university of chicago

sequential entry industry structure and welfare in this paper we reexamine the relationship between potential competition industry structure and welfare in a market subject to a sequential entry threat where firms can make quantity commitments and have access to a constant returns technology it is shown that provided entry is not blockaded the incumbent s will either prevent entry or allow all the potential entrants in furthermore actual entry may decrease but social welfare never goes down with more potential entrants nevertheless with a finite number of potential entrants policies which lower the cost of entry need not be beneficial in welfare terms

implicit contracts with asymmetric information and bankruptcy the effect of interest rates on layoffs this paper develops a model in which a firm writes labour contracts with workers and debt contracts with creditors firms have more information than do the owners of the factors of production and they are also subject to limited liability we show that if the limited liability constraint is binding then the employment level is inefficient relative to a situation of symmetric information the firm is then embedded into a partial equilibrium model in which the real rate of interest is exogenously determined we show that increases in the real rate of interest increase the inefficiency of the optimal employment contract and lead to layoffs in more states of nature than would occur at lower real interest rates recent literature in the area of implicit contracts has shown considerable interest in the assumption of asymmetric information henceforth a i papers by azariadis 1982 green and kahn 1982 and grossman and hart 1981 have all shown that a i will interfere with optimal risk sharing but although these models produce non walrasian outcomes it is not clear that they are capable of explaining the observed variations in employment over the business cycle in the absence of a link between the level of employment and other macroeconomic variables these new versions of contract theory are open to the charge that they are presenting a complicated explanation of frictional unemployment one potential link between variations in output and variations in intertemporal prices is suggested by models which explicitly allow for the possibility of bankruptcy sappington 1983 has shown that bankruptcy will generate inefficient outcomes even between risk neutral agents and farmer 1984 has shown that if sappington type contracts are incorporated into a macroeconomic structure then the resulting model predicts that bankruptcies will vary countercyclically over the business cycle although bankruptcy is important however it is unlikely that bankruptcies alone will account for all of the output loss during a recession the purpose of this paper is to show that the assumptions of a i and limited liability will generate a model in which the employment level is inefficient and in which the magnitude of this inefficiency varies systematically with the expected real rate of interest this model predicts that the observed increase in the incidence of layoffs during recessions is directly attributable to the effects of high interest rates on aggregate supply some evidence of the phenomenon to be explained is presented below

ownership patterns of u s joint ventures abroad and the liberalization of foreign government regulations in the 1980s evidence from the benchmark surveys data from the benchmark surveys of the commerce department show the beginning of a global liberalization in government restrictions on foreign equity in the 1980s this was manifested in a small but unmistakable across the board reduction in the share of 50 50 and minority affiliates out of all u s affiliates in a country across countries there remains a huge variation in this proportion and the second part of the paper seeks to statistically explain this variation in a cross sectional regression analysis

bargaining power of multinationals and host governments one of the outcomes of negotiation between multinationals and host governments in developing countries the extent of foreign ownership of subsidiaries is influenced by the bargaining power of the two parties foreign ownership measured in various ways appears to be affected by the level of technology of the multinational the degree to which a multinational attempts to differentiate its products the extent to which a subsidiary s output is exported to other parts of the multinational the diversity of products offered by the multinational and the extent of competition by other multinationals the relationship between some of these variables and ownership is not a simple one one variable that others have mentioned as probably affecting bargaining power size of the investment in question appears not to play a significant role in government policies toward ownership but many large projects tend to be located in countries that have lenient ownership policies

limited liability contracts between principal and agent abstract the optimal strategy of the principal is examined in an environment where there are ex post limitations on the maximum penalty that can be imposed on a riskneutral agent contrary to the case in which such limitations are not imposed it is in the principal s interest to deliberately forego the opportunity to induce socially efficient behavior and to instead design a contract that induces the agent to realize an efficient outcome only in the most productive state of nature and perhaps in certain very unproductive states the properties of the contract are examined in detail

a model of collusion timing abstract i develop a dynamic model of collusion affording a substantial role to entry heterogeneous firms make collusion entry exit and investment decisions within an evolving environment the collusive agreement adopted is a rule of thumb motivated by the details of collusion in the lysine market it is found that an entrant will wait until it has a market share comparable to its competitors before agreeing to collude allowing for collusive possibilities tends to yield a less concentrated industry with reduced consumer welfare the model characterises events in the lysine market and could provide insights into markets with the potential for collusion and entry and uncertainty about the characteristics of potential entrants

a mechanism design approach to transfer pricing by the multinational firm abstract this paper is about how multinationals choose transfer prices and optimal production levels in the presence of differential corporate income tax rates and local ownership requirements a key featrure of the model is that there is an asymmetric information problem between a parent and its foreign subsidiary we examine the interaction between ownership structure corporate taxes and bargaining power transfer prices induce underproduction compared to the full information case when the parent has the bargaining ability when bargaining is controlled by the subsidiary overproduction obtains the model is used to illustrate how governmental objectives can be accomplished without direct regulation of the transfer price

exploring the impact of trade and investment on income inequality a cross national sectoral analysis of the developed countries this article explores the relationship between international integration and domestic inequality in the developed countries in the mid 1980s and early 1990s the analysis examines two major modes of integration trade and direct investment disaggregating each by economic sector and distinguishing between imports and exports and inbound and outbound flows and stocks in measuring income inequality extensive use is made of micro data sets that have recently become available through the luxembourg income study lis which provides much more detailed and comparable data on income inequality than has heretofore been the case in particular lis data can be aggregated at the level of economic sector and permit the comparison of pre and post government income the study finds few significant relationships between either trade or investment and sectoral income distribution the overall conclusion is that economic globalization is not a critically important factor in explaining recent trends in income inequa

structuring international cooperative ventures we examine the effect of bargaining power and informational asymmetry on the design of international cooperative ventures in the presence of restrictions on equity participation and investment when the bargaining advantage rests with the multinational equity participation restrictions can increase the profits to domestic firms and encourage sub optimal investment policies overinvestment occurs when the multinational s bargaining advantage is reinforced by an informational advantage while underinvestment occurs when the domestic firm possesses the informational advantage in contrast when the bargaining advantage rests with the domestic firm equity participation restrictions do not affect investment levels

efficient contracting with reliance and a damage measure this article reexamines the problem of breach of contract studied by shavell 1980 1984 and rogerson 1984 by considering explicitly the incentive problems that arise from asymmetric information and transaction specific investment we derive the optimal contract which consists of variable price and damage payment schedules each of which is set before any private information is observed we show that the optimal contract attains full classical efficiency

higher growth through the blue ocean strategy implications for economic policy a b s t r a c t higher growth is a key goal of companies governments and societies economic policies often attempt to attain this goal by targeting companies of certain sizes that operate in specific industries and focus on a specific business activity this approach to policy making has considerable shortcomings and seems to be less than fully effective in increasing economic growth we suggest a new approach to policy making that stems directly from the entrepreneurial perspective this approach examines a successful business strategy framework the blue ocean strategy to discover conditions for high growth we test the propositions on empirical data for two cases of successful high growth business namely slovenian gazelles and amazon com the results reveal a gap between the macro level of economic policy making to achieve higher growth and the micro level of business growth the findings call for a change in the focus of economic policies on specific size companies industries and business activities to intraindus try cooperation collaboration between companies of different sizes value innovation and creation of uncontested markets

on delegating price authority to a regulated firm this article models a regulatory environment in which the regulated firm possesses better information about demand conditions than does the regulator the regulator would like to tie prices to the firm s private information in a socially optimal way to do so the regulator must induce the firm either truthfully to reveal private information or equivalently unilaterally to set socially optimal prices this is accomplished by assessing lump sum subsidies or taxes that depend in an appropriate way on the prices announced by the firm this mechanism can be reinterpreted as a two part tariff scheme whereby both the service fee and price per unit respond to shifting demand conditions

managerial incentives investment and aggregate implications scale effects we explore a managerial model of investment behaviour in which an incentive problem arises because one input factor managerial effort is not publicly observed we show that an optimal incentive contract leads to investment levels which are below first best in low states and that this phenomenon can account for greater cyclical variability in aggregate production and investment from the perspective of incentive scheme design a special feature of the model is that screening takes place over two variables investment and output rather than one as is customary

an anatomy of cartel contracts we study cartel contracts using data on 18 contract clauses of 109 legal finnish manufacturing cartels one third of the clauses relate to raising profits the others deal with instability through incentive compatibility cartel organization or external threats cartels use three main approaches to raise profits price market allocation and specialization these appear to be substitutes choosing one has implications on how cartels deal with instability simplifying we find that large cartels agree on prices cartels in homogenous goods industries allocate markets and small cartels avoid competition through specialization

dynamic labor contracts under asymmetric information abstract this paper discusses the distortion of employment within a two period asymmetric information contracting model in which an exogenous demand shock is serially correlated and is known only to firms the obtained results show that serial correlations of the state of nature can cause not only underemployment but also overemployment even when overemployment never occurs in the context of a static asymmetric information contracting model

a rationalization of bonuses penalties and kinked payment functions within an agency model abstract the optimal payment schedule of the simplest principal agent problem can be continuous smooth or kinked or semicontinuous depending on the specifications of objective functions of the principal and or of the agent using the nonsmooth mathematical analysis this article determines a mapping from classes of objective functions into classes of optimal payment functions examples provide illustrations

sustainable collusion in oligopoly with free entry we investigate the stability of collusion in a market where firms cannot prevent entry in a symmetric homogeneous oligopoly there are collusive long run equilibria under which the colluders obtain positive economic rents while they do not prevent entry of firms up to a maximum equal to the largest number of firms sustainable at a single shot equilibrium the collusion is not generous to new entrants their profits are a little better than those associated with the discounted single shot equilibrium eventually entrants obtain profits equal to the incumbent firms we extend the results to asymmetric differentiated oligopolies

rules or discretion in public sector decision making rules and discretion in public sector decision making are compared in a macroeconomic setting where there is a potential role for an active stabilization policy when the policymaker has private information about nominal shocks the credibility of announcements about the state of nature is shown to depend critically on both the policymaker s preferences over output and inflation and on the institutional setting rules or discretion the issue of rules versus discretion is found to depend on the flexibility lost under a rule relative to the timeinconsistency problem arising under discretion

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

delegation as commitment the case of income tax audits in this article we study the value of delegating authority over income tax audit policy arising from the incompleteness of contracts consider a utilitarian government whose ability to commit is limited to aggregate dimensions of its audit policy as publicly verifiable information about detailed allocations of audit budgets is not available we show that the welfare level associated with the full commitment solution can be attained by delegating authority over audit policy to a manager the latter is offered a simple incentive scheme based only on the aggregate variables which are publicly observable in contrast if the government retains authority direct commitment to these same variables does not allow the full commitment welfare level to be achieved thus despite sharing a common informational basis delegation may perform better than centralized arrangements in the presence of incomplete contracts
