fighting multiple tax havens this paper develops a competition theory framework that evaluates an important aspect of the oecd s harmful tax practices initiative against tax havens we show that the sequential nature of the process is harmful and more costly than a big bang multilateral agreement the sequentiality may even prevent the process from being completed successfully closing down a subset of tax havens reduces competition among the havens that remain active this makes their tax haven business more profitable and shifts a larger share of rents to these remaining tax havens making them more reluctant to give up their tax haven business moreover the outcome of this process reducing the number of tax havens but not eliminating them altogether may reduce welfare in the oecd

standard essential patents a major policy issue in standard setting is that patents that are ex ante not that important by being included into a standard may become standard essential patents in an attempt to curb the monopoly power that they create most standard setting organizations require the owners of patents covered by the standard to make a loose commitment to grant licenses on reasonable terms such commitments unsurprisingly are conducive to litigation this paper builds a framework for the analysis of these patents identifies several types of inefficiencies attached to the lack of price commitments and shows how structured price commitments restore competition and why such commitments may not arise spontaneously in the marketplace

ex post participation constraint in a principal agent model with adverse selection and moral hazard abstract this paper analyzes optimal contracting when an agent has private information before contracting and exerts hidden effort that stochastically affects the output additionally the contract is constrained to satisfy the agent s ex post participation we highlight three features of this model first the agent faces countervailing incentives second the separation of types is never optimal third the optimal constant bonus rewarding success is distorted downward below its efficient level

catching the agent on the wrong foot ex post choice of monitoring abstract in a principal agent model with multiple performance measures we show that the principal benefits by choosing ex post which variables will be monitored if it is too costly for one type of agent to mimic all performance measures expected from another type the principal can hope to catch the agent on the wrong foot if the agent tries to misrepresent his type for cases of small asymmetry of information the principal can implement the first best contract for more serious asymmetries of information the first best is not implementable then the low type may be required to overproduce which is in contrast to the traditional result of second best contracting we also obtain a ranking of monitoring instruments according to the frequency of their use

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

collective institutional entrepreneurship and contestations in wind energy in india with 21 136 mw of wind energy installed in 2014 india is considered a success story in terms of net installed capacity few existing studies on indian wind energy have highlighted the important role of institutions and how they stemmed from the work of advocacy groups studies also tend to focus on short time periods this paper uses the notion of collective institutional entrepreneurship to analyze indian wind energy across three time periods 1985 1995 1995 2003 and 2003 2013 the analysis shows that indian wind power development was driven by collective efforts of institutional entrepreneurs using two aggregated strategies that is supportive techno economic and socio political networks and an indigenous innovation infrastructure the paper highlights setbacks controversies and tensions between various entrepreneurship groups and argues that actions must be taken for including actors who have been marginalized

wind energy status in india a short review abstract renewable energy represents an area of tremendous opportunity for india energy is considered a prime agent in the generation of wealth and a significant factor in economic development energy is also essential for improving the quality of life development of conventional forms of energy for meeting the growing energy needs of society at a reasonable cost is the responsibility of the government limited fossil resources and associated environmental problems have emphasized the need for new sustainable energy supply options india depends heavily on coal and oil for meeting its energy demand which contributes to smog acid rain and greenhouse gases emission last 25 years has been a period of intense activities related to research development production and distribution of energy in india though major energy sources for electrical power are coal and natural gas development and promotion of non conventional sources of energy such as solar wind and bio energy are also getting sustained attention the use of electricity has grown since it can be used in variety of applications as well as it can be easily transmitted the uses of renewable energy like wind and solar is rising wind energy is a clean eco friendly renewable resource and is nonpolluting the gross wind power potential is estimated at around 48 561 mw in the country a capacity of 14 989 89 mw up to 31st august 2011 has so far been added through wind which places india in the fifth position globally this paper discusses the ways in which india has already supported the growth of renewable energy technologies i e wind energy and its potential to expand their contribution to world growth in a way that is consistent with world s developmental and environmental goals the paper presents current status major achievements and future aspects of wind energy in india

second best taxation as a game second best theory usually lies in the realm of normative analysis it focuses attention on the best solutions which still can be obtained in problems where constraints of various natures forbid the attainment of first best pareto optimal situations its central concern is the characterization of such second best solutions and a large part of the literature concentrates on the optimal design of taxes or of policies of public firms taking a second best problem we try in this paper to shift the emphasis from normative to positive considerations the solution we are interested in is not optimal with respect to some a priori given social welfare function embodying justice objectives but it is supposed to reflect the power of the different agents in a negotiation process clearly the conceptual tools required for such an analysis are to be found in game theory and it is actually a game theoretical approach that we follow here the model we are looking at is presented in section ii it formalizes one of the simplest second best problems that can be imagined we have a twogood economy with one private good and one public good agents have different wealth in private good and the public good is financed through a wealth tax this latter fiscal system is clearly not flexible enough to adjust contributions with marginal willingnesses to pay so that we actually face a second best situation there is one decision variable in the society the tax rate which determines the public good production about which the agents have conflicting desires to this problem we associate a game which provides a precise framework for the analysis of the power of the agents the positive outcomes of the negotiation process are supposed to belong to the core of this game sections iii and iv concentrate on the analysis of the core the results strongly contrast with those obtained in the classical studies of the core of 67 0022 053 l 81 040067 25 02 00 o

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

energy sufficiency aspirations of india and the role of renewable resources scenarios for future abstract the indian energy scenario has been suffering perennially from problems like energy deficit energy inequity and threats to energy security conventional power resources like coal oil and gas large hydro and nuclear have inherent shortcomings especially in the indian context which make them fall short of fulfilling the energy sufficiency aspirations of india the present paper assesses the validity of the promise offered by renewable energy technologies in this context the existing trends of cumulative installed capacity growth of solar wind small hydro and biomass power in india have been fitted to simple logistic models to forecast the future growth trajectory similarly long term electricity demand projections have been made using logistic models two renewable growth scenarios and three demand growth scenarios have been combined to generate six combined electricity demand renewable growth scenarios the analysis done in the present paper shows that in the most desirable electricity demand renewable growth scenario the percentage share of renewable electricity in the overall electricity mix of india rises steadily from the current 6 to around 43 44 by 2031 32 and then decays gradually to saturate at around 26 27 by 2063 2065 whereas in the most likely scenario it rises steadily to around 29 by 2030 31 and then decays gradually to settle at around 21 by 2064 65 this leaves policymakers with a lot of thinking to do regarding the viability of other alternatives in long term power planning and underscores the need for path breaking r d in the sector

insurance as a lemons market coverage denials and pooling abstract the standard monopoly insurance model with adverse selection implies that there are always gains to trade that only the best unobservable risks can go uninsured and that a profit maximizing menu cannot pool all types we show that insurance provision costs can explain both coverage denials only to those likely to be the worst risks and complete pooling specifically we prove a general comparative statics theorem formalizing coverage denials only to those deemed to be the worst risks and two theorems showing that the insurer offers a single contract complete pooling with either zero or positive coverage we point out some implications of these results for empirical work on insurance our results expand upon a point made by hendren 2013 that the main effect of adverse selection on insurance might not be misallocation in active markets the traditional emphasis after rothschild and stiglitz 1976 but simply in shutting down markets as in akerlof 1970 classic lemons model

signalling with many signals this paper examines a market with asymmetric information where there are many signals available and where both the costs of signaling and the product value may depend on many privately known characteristics under a weak condition on the relationship between the marginal cost of increasing the signals and the product value a separating set exists whereby the value of every seller s product is inferred from the seller s optimal choice of signals the separating set constructed is pareto dominant and corresponds to recently proposed equilibrium notions in signaling and screening models copyright 1987 by the econometric society

essential facility financing and market structure abstract the paper analyzes the funding of an infrastructure project when an incumbent operator has private information about market profitability and the regulator does not have access to taxpayers money an open access policy raises welfare but may make the project non viable since funding must be provided by operators capital contributions we characterize the optimal market structure the regulator can ask the incumbent to bear a higher share of investment cost if the latter insists on an exclusive use yet the incumbent is willing to pay more for exclusivity the higher the demand that is precisely when competition yields the highest benefits at the optimum the incumbent s information is not used to determine market structure we further investigate the implications of this basic result in a dynamic context we show that the monopoly franchise policy is time consistent while an open access policy is not we also demonstrate that a threat of regulatory capture creates an open access presumption last we show that when the decision involves multiple projects monopoly segments should cross subsidize open access ones

the ratchet effect and the coordination of production in the absence of rent extraction valuable to offset the cost these net gains may help explain why the ratchet has been observed in situations as diverse as managerial reward systems in the soviet union and salesman bonus arrangements in capitalist countries

export subsidies as an outcome of the management labor conspiracy a mercantilistic trade policy is often introduced as a tool to generate more jobs in some key industries when employment in an export import industry is perceived to be low the government would be tempted to adopt measures of export promotion import protection to increase it by effectively guaranteeing employment however these policies would reduce incentives for the private sector to reach efficient labor contracts for example the labor union might refuse to sign a profit sharing contract with management and unilaterally demand high wages believing that the resulting loss in competitiveness would not affect the well being of its members since the government would protect the industry it is also conceivable that management and the labor union conspire to reach inefficient contracts so as to invite government intervention in certain cases trade policies only transfer income without any allocative effect this is not merely a theoretical curiosum free trade advocates have often pointed out that protectionist policies would have deleterious effects on the pattern of collective bargaining in the trade sensitive sectors this paper constructs simple models to illustrate this point for export subsidies and so it can be viewed as an addition to the literature that aims to bring attention to the pitfalls of the new mercantilism such as eaton and grossman 1986 dixit and grossman 1986 and horstman and markusen 1986 unlike these studies however the government policies considered here are reactive in the sense that the private sector moves first anticipating the government s response dixit and kyle 1985 carmichael

productive efficiency in public and private firms abstract this paper compares the degree of x inefficiency which emerges as a consequence of the imposition of the optimal incentive contracts in public and private firms using a straightforward principal agent model with two possible states of the world it establishes the rather surprising result that in the good state of the world public ownership always results in a higher degree of productive efficiency

decentralization duplication and delay we argue that although decentralization has advantages in finding low cost solutions these advantages are accompanied by coordination problems which lead to delay or duplication of effort or both consequently decentralization is desirable when there is little urgency or a great deal of private information but it is strictly undesirable in urgent problems when private information is less important we also examine the effect of large numbers and find that coordination problems disappear in the limit if distributions are common knowledge

reputation and the control of pollution this paper investigates the effectiveness of reputation in inducing a polluting firm to self regulate its emissions when consumers have imperfect information in particular we ask to what extent must consumers reward and punish the firm before it chooses self regulation as its dominant strategy we find that if payoffs in the stage game are such that both the consumer and the polluting firm have beliefs that are consistent with each others behaviors then the firm has a positive probability of playing clean in each period of a finite game further we find that a weak reward punishment scheme may have an adverse effect on the environment and that there are both environmental and welfare gains associated with strengthening the scheme

noisy observation in adverse selection models we consider a principal agent contracting problem under incomplete information where some of the agent s actions are imperfectly observable contracts take the form of reward schedules based on the noisy observation of the agent s action we first review situations where the principal can reach the same utility as in the absence of noise then we focus on the use of linear reward schedules which allow universal implementation i e implementation of a given mechanism for any unbiased noise of observation and on quadratic reward schedules which only require the knowledge of the variance of the noise we exhibit sufficient conditions under which linear reward schedules implement a given mechanism finally we characterize necessary conditions for a mechanism to be implementable under noisy observation by a linear schedule and by quadratic schedules we give the geometric intuition behind all results

regulation and legislative choice regulation has economic and political dimensions both of which i endogenize in this hierarchical model in which a legislature chooses by majority rule the mandate of an agency that faithfully regulates a firm with private information about its costs sufficient conditions are given for an equilibrium to exist if there is a strong electoral connection between the benefits delivered to constituents and their electoral support the legislature will choose a regulatory mandate that favors consumer over producer interests and results in regulation that does not maximize expected total surplus political interest in delivering benefits to constituents through factor employment results in a regulatory mandate that yields greater expected total surplus

guilty until proven innocent regulation with costly and limited enforcement abstract we consider optimal regulations for a polluting firm when regulators cannot observe emission control costs and can only observe emissions via costly monitoring fines or subsidies for enforcing compliance are also limited the optimal regulations resemble a deposit refund system the firm reports its emissions and pays an initial tax based on this report if the firm is monitored it receives a rebate when actual and reported emissions coincide the enforcement constraints and the firm s rights determine whether the incentives to reduce emissions are optimally provided by varying the rebate for compliance the monitoring probability or the initial tax

india s on grid solar power development historical transitions present status and future driving forces india with a fast growing demand for electricity and increasing consideration to emissions reduction is investing strongly in renewable electricity generation among renewables the central and state governments have set aspirational targets for on grid solar electricity and legislated several supporting policies to realise these targets as a result of the favourable political environment the development of on grid solar in terms of the rate of growth in installed capacity has been increasing in the recent years and it is expected to continue in the future this paper aims to investigate the impact of historical transitions of india s electricity sector on the ongoing development of on grid solar electricity and to explore the prospect of solar sector development in the future first of all we investigate how the historical transformation of governmental intervention s approach intertwined with the gradual shift of the source of generation has paved the way for the current achievements in on grid solar electricity second we envision the future challenges and opportunities for the development of solar sector by looking ahead and discussing the continuity of government s support and the prospective competitions between different sources we conclude the paper with some required steps to be taken in order to secure the achievement of the targets in solar electricity in the future

the regulation of multiproduct firms part i theory abstract this paper develops a normative model of the regulation of a multiproduct firm with private information about its technology and cost reducing activity it first characterizes the optimal regulatory scheme and illustrates it through examples it then derives necessary and sufficient conditions for the pricing incentive dichotomy to hold i e conditions under which the cost reimbursement rule but not pricing is used to provide incentives last the paper studies the regulation of the multiproduct firm in a general equilibrium framework both to assess the validity of the partial equilibrium approach and to formalize the notion of taxation by regulation

the economics and politics of regulation this article provides a critical survey of the literature on the economics and politics of regulation after some conceptual clarifications the article surveys the evolution of perspectives on regulation during the post second world war period emphasizing especially the interactions between intellectual changes and real world economic and political developments it then looks at some themes that are neglected in the current literature the inevitability of regulation the need to create and not simply regulate markets distributional issues dynamic considerations and the politics of regulation and suggests that incorporating these themes more closely into the discussion will improve our understanding in this area copyright 1997 by oxford university press

permanent versus interim regulations a game theoretic analysis abstract when a regulator anticipates learning about the benefits or costs of regulations over time questions can be raised about the appropriate regulatory policy this paper compares permanent and interim regulations in a setting with initially uncertain pollution damages a fixed capital input and costly enforcement the analysis shows that neither policy is first best conditions under which one policy dominates the other are identified with the help of a simulation the results indicate that permanent regulations may be preferable to interim regulations even when there is substantial uncertainty about damages

role of policy in deployment of wind energy evidence across states of india abstract this paper is an enquiry into the role of state policies in influencing wind installed capacity the paper studies the impact of policies on deployment of wind potential across the states of india over two decades aggregate indices are computed for each of the seven wind resourceful states of india indicating attractiveness for installed capacity of wind energy for computing the indices four policies feed in tariff renewable purchase obligation banking facility and wheeling charges are considered panel data techniques are then employed to investigate the impact of the policy differences on wind potential deployment over the 19 year period 1993 2012 after controlling for three state specific factors the controlling factors include per capita income of the state power deficit and ratio of installed capacity of wind to geographic potential indicating unmet capacity the results show that that policy index positively impacts wind deployment whether control variables are included or not moreover the control factors like the per capita income of the state and unmet capacity have positive influence over the investment in wind energy

a reduced form optimal nonlinear income tax problem abstract for a finite population with quasilinear preferences it is shown how mirrlees optimal nonlinear income tax problem can be simplified to a reduced form problem involving only the allocation of the consumption good this result is a finite version of a proposition established in the continuum by s lollivier and j c rochet

optimal linear income tax with random revenue abstract this paper introduces the concept of risk attitudes a government may take toward random revenue in the design of a linear income tax it shows that the familiar trade off formula between equity and efficiency can be derived either by assuming a risk neutral government attitude toward random revenue or by assuming no randomness of revenue we provide numerical analysis to demonstrate that optimum tax schedules for a non risk neutral government can significantly deviate from those for a risk neutral government

public versus regulated private enterprise a comparison of public enterprise with regulated private enterprise shows that the efficiencies of privatization stem from the insulation it brings from arbitrary political and self serving influences the critical insulation springs from the costliness of interventions when there is a regulatory compact in place that protects private property from expropriation while it also corrects for market failures that same insulation means that public enteprise is a better form of organization for activities that call for a response to public interest exigencies which cannot be specified in advance or reliably adjudicated after the fact the analysis emphasizes that an appropriate regulatory compact requires institutional support international organizations that seek to implement privatization should consider promoting credible regulatory commitment by requiring countries to execute explicit regulatory compacts and by bringing to bear the weight of their continuing relationship as a means of motivating the countries to conform to such strictures

strategic trade policy design with asymmetric information and public contracts this paper examines strategic trade policy under asymmetric information with publicly observable contracts we analyse both the cases of unilateral and bilateral intervention we find that the requirement of incentive compatibility undermines the strategic precommitment effect when public funds are costly even with no restrictions on the form of the policies second when firms sell substitute goods the introduction of a rival interventionist government may reduce the cost of informational rents to each government third it turns out that under bilateral intervention there exists a continuum of symmetric equilibria with levels of output and corresponding levels of welfare in the exporting countries which can be ranked the requirement of ex post participation constraints for the firm limits the set of subsidies which can be offered to the firm in particular under bilateral intervention the equilibrium levels of output which are implemented under adverse selection are below their values under ex ante uncertainty i e below the equilibrium levels of output which are achieved when firms sign their contracts before the realization of their costs ever since the inception of research on strategic trade policy with the seminal paper by brander and spencer 1985 economists have been warning that the informational requirements of rent shifting policies are enormous and unlikely to be met in practice because the policy recommendations are highly sensitive to the particularities of the market in response a number of recent papers have begun to address the specific ways that informational failures affect policy and to modify policy recommendations to take such failures into account this paper analyses the implications of asymmetric information for strategic trade policy under both unilateral and bilateral intervention our complete information benchmark is a simple trade policy designed to shift rents similar to brander spencer two firms are competing in a third country and receive export subsidies from their respective governments however we place no restrictions on the form of these export policies previous literature has shown that under complete information a large number of outcomes may be sustained as equilibria of delegation games such as this moreover the introduction of uncertainty about the state of nature on the part of both

participation constraints in adverse selection models abstract this paper characterizes the optimal contract offered by an uninformed principal to an informed agent when the latter s reservation utility depends on his type the informational rent is nonmonotonic so that interior types may have a vanishing rent or be excluded from trade the paper identifies conditions for the optimal contract to be separating to be nonstochastic and to induce full participation it also discusses the nature of the solution when bunching occurs the results are applied to nonlinear pricing under price cap regulation and bypass competition and to competition in nonlinear pricing journal of economic literature classification numbers d82 d42 d23 d78 l51 l15

ends against the middle determining public service provision when there are private alternatives abstract public provision of a service coexists with private market provision the quality of public provision is determined by majority vote preferences are not single peaked owing to the presence of private alternatives we identify two cases in one majority voting equilibrium always exists and the median income voter is pivotal in the other a necessary condition for equilibrium indentifies the pivotal voter who must have income below the median when equilibrium exists a coalition of middle income households who consume the public alternative will be opposed by a coalition of rich and poor households with the rich choosing private consumption

optimal border policies for invasive species under asymmetric information this paper analyzes the problem faced by a border protection agency if endogenous exporter abatement activities affect invasive species risk allowing for unobservable differences in abatement cost we show how the optimal inspection penalty regime differs from the symmetric information case departing from previous literature we allow for technical assistance a policy instrument specifically permitted and commonly employed under article 9 of the world trade organization sanitary and phytosanitary agreement we find the information asymmetry can make it optimal for the importing country to provide technical assistance grants for exporter risk abatement even if it would otherwise be inefficient further we show that fungibility of technical assistance with inputs in other sectors of the exporting economy affects the qualitative nature of optimal policy if technical assistance has no outside value in the exporter s country optimal policy is characterized by a menu of contracts balancing higher tariffs with lower penalties for being caught with an invasive if technical assistance can be used in other sectors of the exporter s economy it can introduce countervailing incentives making a uniform tariff penalty combination optimal

evaluation of credit risk based on firm performance abstract this paper investigates whether productive inefficiency measured as the distance from the industry s best practice frontier is an important ex ante predictor of business failure we use samples of french textiles wood and paper products computers and r d companies to obtain efficiency estimates for individual firms in each industry these efficiency measures are derived from a directional technology distance function constructed empirically using non parametric data envelopment analysis dea methods estimating binary and ordered logit regression models we find that productive efficiency has significant explanatory power in predicting the likelihood of default over and above the effect of standard financial indicators

econometrics of first price auctions in this paper we propose an estimation method for the empirical study of theoretical auction models we focus on first price sealed bid and descending auctions and we adopt the private value paradigm where each bidder is assumed to have a different private value only known to him for the object that is auctioned following mcfadden 1989 and pakes and pollard 1989 our proposed method is based on simulations specifically the method relies on a simulated nonlinear least squares objective function appropriately adjusted so as to obtain consistent estimates of the parameters of interest we illustrate the proposed method by studying a market of agricultural products where descending auctions are used our analysis takes into account heterogeneity of the auctioned objects and the fact that only the winning bid is observed we estimate the parameters that characterize the distribution of the unobserved private values for each auctioned object

optimal capital structure in agency relationships we analyze the optimal design of capital structure in agency relationships when a risk averse principal controls the agent s capital structure she awards a larger equity stake to outsiders the smaller the agent s productivity when she controls both the timing and the terms of the agent s financing the principal shifts to equityholders all risk associated with stochastic production and with the agent s unknown productivity when the principal dictates only the terms of financing only the former risk is borne by equityholders when the principal is sufficiently averse to risk she affords the agent no choice among incentive schemes

optimal strategic trade policy under asymmetric information abstract when cost is private information in the brander spencer model the home government is confronted by a decision of choosing between two policy options a menu of policies and a uniform policy the former induces separation and so reveals the cost information to the foreign competitors the latter helps the weak firm by concealing the cost information the main result from this study is that policy menu is preferred to uniform policy under cournot competition while the opposite occurs under bertrand competition

incentive regulatory policies the case of public transit systems in france we assess the empirical relevance of the new theory of regulation using a principal agent framework to study the regulatory schemes used in the french urban transport industry taking the current regulatory schemes as given the model of supply and demand provides estimates for the firms inefficiency the effort of managers and the cost of public funds it allows us to derive the first best and second best regulatory policies for each network and compare them with the actual situation in terms of welfare loss or gain fixed price policies lie between fully informed and uninformed second best schemes cost plus contracts are dominated by any type of second best contract from these results we may conjecture that fixed price contracts call for better informed regulators

a reexamination of the optimal nonlinear income tax abstract this paper investigates mirrlees model of optimal income taxation it provides a concrete example of utility and density functions for which the solution to the usual first order model is not implementable i e and example where the first order approach does not work adding second order conditions leads to an extended model and to implementable solutions if these conditions are binding one gets a kink in the optimal net income schedule and bunching of individuals occurs the properties of an optimal nonlinear income tax are reexamined within the extended model

departmentalization and stochastic dissimilarity abstract when activities within the organization are confronted with different types of stochastic environments the owner of the firm has to evaluate the benefits and the costs involved in establishing multiple specialized divisions the benefit from departmentalization is the ability to better match incentives to the extent of uncertainty confronting different activities the cost of departmentalization is the increase in the number of required managerial positions which implies that the owner has to deal with a bigger number of individuals that can assume only limited risk only when the extent of stochastic dissimilarity among activities is significant can the benefit more than outweigh the cost

on the design of incentive schemes under moral hazard and adverse selection abstract this paper characterizes a class of optimal incentive schemes in a simple principal agent model which allows for moral hazard and adverse selection we show that incentive compatible allocation can always be approximately implemented through a menu of quadratic incentive schemes it is also proved that the set of incentive compatible allocations is independent of the distribution of the additive uncertainty which affects the outcome informational requirements and economic interpretation of quadratic and linear schemes are discussed

using cost observation to regulate firms the paper emphasizes the use of accounting data in regulatory or procurement contracts when the supplier 1 has superior information about the cost of the project and 2 invests in cost reduction the main result states that under risk neutrality the supplier announces an expected cost and is given an incentive contract linear in cost overruns this optimal contract moves toward a fixed price contract as the announced cost decreases an investment choice is then introduced and the use of a rate of return regulation is studied

a complete solution to a class of principal agent problems with an application to the control of a self managed firm this paper considers a class of principal agent problems which have the following features 1 there is adverse selection because the principal ignores the value of one parameter of the agent s true characteristics 2 leaving aside the information parameter the principal s welfare as well as the agent s welfare depend on two types of variables observable to both of them the first ones possibly multidimensional are called action variable s and the second one which is one dimensional has in general the meaning of a money transfer 3 the principal is a stackelberg leader of the two person game he can commit himself to decision rules which are admissible on informational grounds he optimizes within the adequate class taking into account besides the agent s reaction one constraint which has generally the meaning of an individual rationality constraint and sometimes of a feasibility constraint the optimization is limited to the class of non stochastic mechanisms 4 the problem can also receive an alternative interpretation the principal faces a continuum of agents of unknown characteristics the distribution being known however stylized principal agent problems of this type have often been considered in the economic literature in particular the reader will later be able to recognize that the standard income tax model a la mirrlees 1971 the quality or quantity choice model of the monopolist a la mussa and rosen 1978 or maskin and riley 1982 and the model of government regulation of the private monopolist of baron and myerson 1982 all belong to

regulation competition and asymmetric information abstract this article studies a model of regulation under asymmetric information when there exists a competitive fringe of unregulated alternative producers the correlation between the unknown cost parameters of the fringe and of the regulated firm allows the regulator to use the threat of entry by the fringe to reduce the informational cost of regulation the presence of the fringe is welfare enhancing the allocative distortions can be larger or smaller than those in the no fringe case and the optimal contract sometimes allows inefficient entry the optimal contract can exhibit non standard bunching phenomena and discontinuities

on the design of incentive mechanisms in environmental policy the theory of incentives in environmental policy is concerned with the problem an environmental authority faces when its own objectives do not coincide with those of the polluters negative externalities in production and consumption degrade the quality of the environment in an excessive way the public goods property of natural resources like air and water is a standard example of the failure of markets and hence for the need of public regulation it is the task of the environmental authority the principal to invent instruments for environmental policy in order to internalize the social cost of production and consumption caused by the polluters the agents

on efficiency inducing taxation for a non renewable resource monopolist the problem of using taxes to induce a monopolist supplier of a non renewable resource to extract efficiently has been solved under the assumption that the government has perfect information about the monopolist s cost function and reserves and is able to precommit to an entire sequence of taxes over time we extend this literature by constructing an efficiency inducing tax mechanism that does not require the government to have any information about the cost function or reserves and which does not require it to precommit to a sequence of taxes over time

auctioning and bargaining an econometric study of timber auctions with secret reservation prices this article considers a first price sealed bid auction at which the seller s reservation price is not announced in advance we allow for a second round of bargaining and consider the nash bargaining outcome when the object is unsold after the auctioning round we characterize the bidders and seller s bayesian nash equilibrium strategies the distributions of the buyers and seller s private values are estimated by nonlinear least squares from auction data on standing timber while solving numerically the differential equations characterizing the seller s and buyers equilibrium strategies the performance of the estimated model is then compared to a model in which the players behave myopically

regulation competition and liberalization in many countries throughout the world regulators are struggling to determine whether and how to introduce competition into regulated industries this essay examines the complexities involved in the liberalization process while stressing the importance of case specific analyses this essay distinguishes liberalization policies that generally are procompetitive from corresponding anticompetitive liberalization policies

the structure of firms abstract this paper studies different organizational forms within a single framework the u form is modelled as a two round communication game between a principal and agents with unobservable efforts and adverse selection problems the m form is modelled by considering a one round communication game with pure adverse selection feasible and optimal mechanisms are characterized the profit functions are derived and an extension of hotelling s lemma proved in the absence of the control loss problems flowing form the unobservability of agent effort levels the u form will be superior to the m form both forms will be superior to the corrupted m form

state regulation and university behavior abstract the impact of state regulation on the economic behavior of american public research universities is studied using a unique sample of data on costs outputs and regulation measures for 98 institutions the university cost structure is modeled by a multiple output translog cost function explicitly allowing for the impact of state regulation regulating non faculty salary expenditures and the spending of non state revenues decreases costs while regulating faculty salary expenditures increases costs given the same output levels the results are interpreted in terms of the principal agent relationship of state regulators and universities efficiency gains and losses depend on the relative accuracy of state information on the production process

optimal resource royalties with unknown and temporally independent extraction cost structures the authors study optimal nonrenewable resource royalty contracts when the extracting agent has private information on costs this is a dynamic incentive problem in which the repeated relationship between the principal and the agent is constrained by initial reserves commitment is limited to one period and costs are intertemporally independent compared with full information extraction information asymmetry shifts production to the future when the optimal contract requires exhaustion in two periods when exhaustion by all types in two periods is not warranted the effect on the terminal period is ambiguous and the output of even the lowest cost firm is always distorted copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

multi round procurement auctions with secret reserve prices theory and evidence when a secret reserve price is used in an auction the auctioneer cannot guarantee that the good can be sold out at the auction and can reauction the unsold objects in the next round motivated by this interesting feature observed in the procurement auctions organized by the indiana department of transportation we construct a dynamic bidding model in multi round procurement auctions with secret reserve prices and evaluate how the release of the auctioneer s reserve price affects bidders bidding behavior and the auctioneer s expected payment our theoretical model predicts that the equilibrium bids uniformly decline over stages and the numerical analysis of our model indicates that hiding the reserve price may be better than announcing it for the auctioneer under some specifications of underlying distributions we develop an empirical model with bidders discount factor equal to zero to recover the unknown structural parameters and to conduct counterfactual analyses copyright 2008 john wiley sons ltd

economic reform and dynamic political constraints in this paper we examine the impact of political constraints on economic reform plans with special reference to the transition from centrally planned to market economies we analyse the problem of an agenda setting reform minded government facing a bureaucracy or industrial sector for which allocative efficiency requires redundancies and an increase in work intensity the government also tries to minimize the rents conceded to its heterogeneous workforce we examine two types of political constraints unanimity rule and majority rule both in a one period and a two period horizon the main results are the following first of all we show how adverse selection and time consistency may generate the widely observed feature of gradualism as an ingredient of an optimal reform second under a majority rule it is shown to be possible for the government to obtain a majority vote for a reform scheme that intertemporally hurts majority interests indeed the government can improve rent extraction through the strategic use of the threat of future proposals the group which expects to be in the minority tomorrow may accept concessions while its votes can be used to extract rents from another group these results suggest that in a dynamic context democratic constraints should not be overestimated as an obstacle against efficiency enhancing economic reforms the results of this paper may throw some light on the political economy of current reforms in eastern europe governments and political decision makers in general always face political constraints when elaborating reform proposals they know that the need to overcome potential opposition from various groups of the population constrains proposals for change political constraints vary depending on the specific institutional structure of society and are clearly different under a military dictatorship than under a parliamentary democracy the role of political constraints seems particularly important in eastern europe today where new democratic governments face the huge task of achieving the transition to a market economy while the introduction of democracy may have removed some important obstacles to economic change namely the veto power of a powerful nomenclatura under communist one party rule fears are expressed that it could potentially jeopardize economic reforms which may during the transition period hurt a majority of the population what can economic theory tell us about optimal economic reform under political constraints this paper starts addressing this ambitious question by looking at structural reform focusing on a restructuring of economic sectors which requires massive redundancies and a significant rise in labour productivity our model illustrates the case of planning

good regulatory regimes assuming simple functional forms numerical methods are used to analyze linear regulatory rules that include cost plus and price cap regimes regulators are assumed to observe actual cost but not the disutility of cost reduction and are assumed unable to impose taxes or make transfers best linear regimes depend importantly on the level and form of uncertainty the regulatory objective function and the firm profitability constraint under uncertainty regimes in which price depends in part on actual cost generally substantially outperform pure price caps particularly in terms of consumers surplus

incentives and optimal size of local jurisdictions abstract a model of optimal territorial decentralization is presented in which smaller local governments have an informational advantage concerning public goods production costs and the central government has imperfect information on spillover effects induced by local projects the attention is focused on the optimal size of local entities and on the shape of transfer schedules from the central government to local jurisdictions the optimal territorial organization is a compromise between small jurisdictions so as to benefit from the geographical proximity effect on information and large entities in which spillover effects are more easily internalized by means of linear or non linear taxation schemes implemented by the centre

small pollution markets tradable permits versus revelation mechanisms abstract a simple two period model with two polluters is analyzed they emit a homogeneous hazardous substance and they are given tradable permits to pollute the social planner issues permits and tries to learn the cost of reducing pollution by observing the quantity of permits traded in the first period it is shown that although efficient trade is prevented by strategic considerations by the polluters the planner learns something from observing only quantities comparisons are made between this approach and that of mechanism design and it is concluded that the latter is superior in theory but sensitive to collusion by the firms

national vs european incentive policies bargaining information and coordination abstract we build a hierarchical model of contractual relationships under moral hazard to address issues about subsidiarity i e optimal de centralization of incentive industrial policies at the national level or at the european community level incentive policy is viewed as an incentive contract for producers who take unobservable decisions that have spillover effects across member states a community agency designs contracts for producers and contractual compensatory transfers between states on the basis of its observations then national regulators and their home producers negotiate according to a generalized nash bargaining a national contract that complements the community contracts given that national regulators will have access to more observations on the producers activities in this setting we show that full centralization is never optimal we give sufficient conditions for complete decentralization to be optimal and when both policies are present we characterize how they interact to provide incentives to producers

contract design and bargaining power abstract it is a common assumption in contract theory that the uninformed side makes a take it or leave it proposal in contrast this paper explores a model which allows a shift in bargaining power continuously between the two parties endowing the informed side with more bargaining power gradually reduces distortions

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

two part tariffs with quality degradation abstract this paper examines a firm s incentive to sell a service that is of lower quality when the firm offers a menu of two part tariffs each tariff is characterized by a fixed fee together with two screening instruments these being a uniform per unit charge and a quality restriction we find that allocation of quality is monotonic in type while per unit charge might be non monotonic the results thus contradict one of the most established insights in nonlinear pricing that the per unit charge should be monotonically decreasing over the type space we show that this practice increases welfare due to increased consumption efficiency

competing vertical structures precommitment and renegotiation we consider a model where two agents privately informed about their own characteristics play a normal form game on behalf of two uninformed principals we analyze the existence of precommitment effects through public announcements of contracts in a model where agency contracts designed ex ante can always be secretly renegotiated at the ex ante and interim stages we show that the existence of precommitment effects depends both on the strategic complementarity of the agents actions and on the direct effect of the opponents actions on each principal s welfare in our model the possibility of renegotiation is crucial for the existence of precommitment effects the results are introduced through an example of cournot and bertrand competition between firms viewed as vertical structures
