a dynamic theory of collective goods programs a collective goods program such as an entitlement program distributes benefits and costs according to constituents characteristics this paper presents a dynamic theory of the legislative choice of collective goods programs based on a sequential model of proposal making and voting in a majority rule legislature where the status quo in a session is given by the program last enacted a stationary markov perfect equilibrium is characterized for a unidimensional collective goods program and yields a generalized median voter theorem comparative statics on preferences and legislative procedures and a characterization of the dynamics of such programs equilibrium programs can expand or contract over time but they ultimately converge to the median on the path to that point legislators may act strategically to address the durability problem that a future legislature can undo the actions of the present legislature by strategically positioning the status quo to limit the changes that future legislatures can make

efficient and durable decision rules with incomplete information we compare six concepts of efficiency for economies with incomplete information depending on the stage at which individuals welfare is evaluated and on whether incentive constraints are recognized an example is shown in which an incentive efficient decision rule may be unanimously rejected by the individuals in the economy we define durable decision rules which can resist such unanimous rejection and show that efficient durable decision rules exist

a solution concept for majority rule in dynamic settings we define and explore the notion of a dynamic condorcet winner dcw which extends the notion of a condorcet winner to dynamic settings we show that for every dcw every member of a large class of dynamic majoritarian games has an equivalent equilibrium and that other equilibria are not similarly portable across this class of games existence of dcws is guaranteed when members of the community are sufficiently patient we characterize sustainable and unsustainable outcomes study the effects of changes in the discount factor investigate efficiency properties and explore the potential for achieving renegotiation proof outcomes we apply this solution concept to a standard one dimensional choice problem wherein agents have single peaked preferences as well as to one involving the division of a fixed aggregate payoff

ex ante incentive efficient trading mechanisms without the private valuation restriction abstract the private valuation assumption found in most trading mechanism design papers rules out markets whose valuation structure generates externalities between traders this paper characterizes the set of ex ante incentive efficient trading mechanisms for a large class of markets that do admit such externalities and for bilateral trade markets establishes the impossibility of a first best solution across a class of trading problems employing uniform priors and linear valuation structures this paper also compares levels of market efficiency for varying numbers of traders

energy substitution effect on transport sector of pakistan a trans log production function approach abstract transport sector of pakistan is one of the highest fossil fuel consumption and carbon dioxide co2 emission sector as a key user of fossil fuel energy pakistan s transport sector has created many problems i e noise air pollution co2 emissions and environmental problem in this study trans log production function model for pakistan s transport sector is established and input factors of labor capital and energy consumption are comprised the output elasticity of an individual input elasticity between a pair of factors and elasticity of substitution between input factors are analyzed to manage the multicollinearity issue ridge regression is applied at different values of k from 1991 to 2018 the outcomes show that output elasticities and a pair of input factor s elasticities are increasing the elasticities of substitutions between labor energy consumption and capital energy consumption show higher outcomes because of the more elevated amount of substitution elasticities the substitution elasticity between labor and capital starts from 0 9797 to 0 9326 with slightly decreasing trend the outcomes suggest that maximum output can be achieved by increasing capital and energy technologies by allocating the maximum capital in the transport industry energy saving technologies substitution between energy and capital and substitution among capital labor can enhance environmental protection in the above s view function the present study estimates the level of energy saving and co2 emissions reduction under the different scenarios from 2015 to 2018 the policy suggestions of the results are given below

a study on exergetic efficiency vis a vis sustainability of industrial sector in bangladesh abstract industrial sustainability has gained huge attention in the scientific community owing to the concern of global warming establishing sustainability indicators by the application of exergy analysis can guide and motivate industrial sustainability in this context an attempt is made to establish sustainability indicators for the industrial sector different measures to improve the sustainability of the industrial sector of bangladesh are also discussed based on the energy consumption data from the year 2000 2015 energy exergy and sustainability analyses are performed it is found that the energy efficiency varies from 55 01 to 59 67 and exergy efficiency varies from 53 11 to 56 97 exergy efficiency is found to be at lower side due to the accounting of irreversibility various sustainability indicators such as sustainability index depletion number exergetic renewable share cumulative exergy loss and non renewable exergetic share have been studied as well it is observed that depletion numbers vary from 43 to 45 and the sustainability index varies from 2 21 to 2 32 non renewable exergetic share is as high as 98 and maximum cumulative exergy loss is found to be 217 3 pj in 2015 improvement potential shows a continuous increase from 22 75 in 2000 to 101 89 in 2015 waste heat recovery energy audit waste minimization and adopting renewable energy sources are recommended to increase the efficiency and sustainability of this sector the outcome of this study reveals that exergy analysis is an effective technique to develop energy conservation policies for this sector

strategic liquidity supply and security design we study how securities and issuance mechanisms can be designed to mitigate the adverse impact of market imperfections on liquidity in our model asset owners seek to obtain liquidity by selling claims contingent on privately observed future cash flows liquidity suppliers can be competitive or strategic in the optimal trading mechanism associated to an arbitrary given security issuers with low cash flows sell their entire holdings of the security while issuers with high cash flows are typically excluded from trade by designing the security optimally issuers can avoid exclusion altogether we show that the optimal security is debt because of its low informational sensitivity debt mitigates the adverse selection problem furthermore by pooling all issuers with high cash flows debt also reduces the ability of a monopolistic liquidity supplier to exclude them from trade in order to better extract rents from issuers with lower cash flows

the principal agent relationship with an informed principal ii common values in many circumstances a principal may have relevant private information when she proposes a contract to an agent we analyze such a principal agent relationship as a noncooperative game the principal proposes a contract which is accepted or rejected by the agent who for most of our analysis has no private information the contract is executed if accepted otherwise the reservation allocation takes effect this allocation may be determined by a pre existing contract which the principal by her proposal is attempting to renegotiate or it may simply be the no trade point in this paper we assume that the principal s information directly affects the agent s payoff before solving the game we discuss pareto efficiency with asymmetric information we define an incentive compatible allocation to be weakly interim efficient wie if there exists no alternative incentive compatible allocation that both parties prefer for all possible beliefs that the agent might have about the principal s private information type we show that any wie allocation is interim efficient ie for some beliefs the rothschild stiglitz wilson rsw allocation relative to the reservation allocation l is the allocation that maximizes the payoff of each type of principal within the class of incentive compatible allocations that guarantee the agent at least the utility he gets from a irrespective of his beliefs about the principal s type the equilibrium set of the contract proposal game consists of the allocations that weakly pareto dominate the rsw allocation thus there is a unique equilibrium outcome if and only if the latter is ie and the equilibrium outcome is the rsw allocation itself after characterizing the equilibrium allocations we study those that are renegotiation proof when either the principal or the agent leads the renegotiation we then compare our contract proposal game which is a signaling model with its screening counterpart we conclude by extending our results to the case in which the agent as well as the principal has private information under the assumption of quasi linear preferences

predictability and power in legislative bargaining the rules and procedures of legislatures often provide legislators with information bearing on the identities of upcoming proposers for a broad class of legislative bargaining games we establish that markovian equilibria necessarily deliver all economic surplus to the first proposer whenever the information structure permits the legislators to rule out some minimum number of proposers one round in advance this result holds regardless of the recognition process and even if players vary in patience and risk aversion it raises the possibility that procedures adopted in the interest of transparency may contribute to the imbalance of political power

a carrot and stick approach to agenda setting this paper models a legislature in which the same agenda setter serves for two periods showing how he can exploit a legislature completely in the first period by promising future benefits to legislators who support him in equilibrium a large majority of legislators vote for the first period proposal because they thereby maintain the chance of belonging to the minimum winning coalition in the future legislators may therefore approve policies by large majorities or even unanimously that benefit few or even none of them the results are robust but institutional arrangements such as entitlements can reduce the agenda setter s power by reducing his discretion to reward and punish legislators and rules such as sequential voting can increase a legislator s ability to resist exploitation

bargaining in legislatures bargaining in legislatures is conducted according to formal rules specifying who may make proposals and how they will be decided legislative outcomes depend on those rules and on the structure of the legislature although the social choice literature provides theories about voting equilibria it does not endogenize the formation of the agenda on which the voting is based and rarely takes into account the institutional structure found in legislatures in our theory members of the legislature act noncooperatively in choosing strategies to serve their own districts explicitly taking into account the strategies members adopt in response to the sequential nature of proposal making and voting the model permits the characterization of a legislative equilibrium reflecting the structure of the legislature and also allows consideration of the choice of elements of that structure in a context in which the standard institution free model of social choice theory yields no equilibrium

bargaining in standing committees with an endogenous default committee voting has mostly been investigated from the perspective of the standard baron ferejohn model of bargaining over the division of a pie in which bargaining ends as soon as the committee reaches an agreement in standing committees however existing agreements can be amended this article studies an extension of the baron ferejohn framework to a model with an evolving default that reflects this important feature of policymaking in standing committees in each of an infinite number of periods the ongoing default can be amended to a new policy which is in turn the default for the next period the model provides a number of quite different predictions i from a positive perspective the key distinction turns on whether the quota is less than unanimity in that case patient enough players waste substantial shares of the pie each period and the size principle fails in some pure strategy markov perfect equilibria in contrast the unique markov perfect equilibrium payoffs in a unanimity committee coincide with those in the corresponding baron ferejohn framework ii if players have heterogeneous discount factors then a large class of subgame perfect equilibria including all markov perfect equilibria are inefficient

on the failure of core convergence in economies with asymmetric information in interim economies with asymmetric information we show that the coarse core of wilson 1978 does not converge to price equilibrium allocations as the economy is replicated this failure of core convergence is a basic consequence of asymmetric information and extends to any reasonable notion of either interim core or price equilibrium

optimal domestic regulation under asymmetric information and international trade a simple general equilibrium approach we investigate the design of domestic incentive regulations in a small economy opened to trade and its implications for international specialization and for trade openness to remain welfare improving more specifically we append to an otherwise standard 2 2 heckscher ohlin model of a small open economy a continuum of intermediate sectors producing nontradable goods used in tradable sectors those goods are produced by privately informed regulated firms asymmetric information induces distortions with general equilibrium impacts the small economy becomes relatively richer in the informationally sensitive factor so that asymmetric information might reverse trade patterns free trade is pareto dominated by autarky when it exacerbates agency distortions

the power of the last word in legislative policy making we examine legislative policy making in institutions with two empirically relevant features agenda setting occurs in real time and the default policy evolves we demonstrate that these institutions select condorcet winners when they exist provided a sufficient number of individuals have opportunities to make proposals in policy spaces with either pork barrel or pure redistributional politics where a condorcet winner does not exist the last proposer is effectively a dictator or near dictator under relatively weak conditions

dynamic legislative policy making abstract we prove existence of stationary markov perfect equilibria in an infinite horizon model of legislative policy making in which the policy outcome in one period determines the status quo for the next we allow for a multidimensional policy space and arbitrary smooth stage utilities and we assume preferences and the status quo are subject to arbitrarily small shocks we prove that equilibrium continuation values are differentiable and that proposal strategies are continuous almost everywhere we establish upper hemicontinuity of the equilibrium correspondence and we provide weak conditions under which each equilibrium of our model determines an aperiodic transition probability over policies we establish a convergence theorem giving conditions under which the invariant distributions generated by stationary equilibria must be close to the core in a canonical spatial model finally we extend the analysis to sequential move stochastic games and to a version of the model in which the proposer and voting rule are determined by play of a finite perfect information game

contract delegation with bargaining i introduction public procurement is a very important part of economic activity it accounts for about 20 of gross domestic product gdp in the united states and 16 in the european union eu countries 1 therefore it is not surprising that many interest groups are at the stake whenever aspects of public procurement procedures are discussed to limit the influence of these groups the purpose of legislation in the united states and the european community has been to unify public procurement procedures and restrict the discretionary power of contracting officers and agencies at lower administrative levels the federal acquisition regulation far in 2005 in the united states and directive 2004 18 ec of the european parliament in 2004 are examples of this one of the most important aspects in public procurement is the extent to which subcontracting is allowed traditionally subcontracting has been judged negatively for example in construction which amounts to a substantial part of public procurement the far prevents contracts from being awarded to a single firm that supplies both design and engineering services i e it requires contract centralization however recently most states have legislations that allow for exceptions like the use of the design build method i e they allow contract decentralization lam chan and chan 2006 report that nowadays more than one third of the construction projects in the united states and up to 50 in japan use the design build approach economic theory should explain whether this is because of the increased influence of pressure groups or if there exists an economic rational for this tendency however economic theory has had difficulty in explaining the superiority of subcontracting to see this consider a general contractor or principal who needs two suppliers or agents to realize a project either he she can contract directly both of them or contract only one supplier and let him her subcontract the other subcontracting obviously implies a loss of control over the subcontractee s contract for the general contractor however because he she can always replicate the same contracts if he she contracts directly with both suppliers it is not easy to see the advantages of subcontracting a common assumption in this literature is that the principal has all the bargaining power and can make a take it or leave it offer to the agent regarding public procurement this is a realistic assumption in cases in which there are many suppliers but it fails to apply in cases in which the principal only can choose among a small number of suppliers for example this is the case in public procurement of defense systems aeronautic and space equipment or specific construction facilities such as water depuration plants airports or electric power plants although procurement in these cases is also based on fixed price cost reimbursement and incentive contracts usually it also allows for negotiations so section 15 3 of far states that negotiations are exchanges in either a competitive or sole source environment between the government and offerors that are undertaken with the intent of allowing the offeror to revise its proposal these negotiations may include bargaining bargaining includes persuasion alteration of assumptions and positions give and take and may apply to price schedule technical requirements type of contract or other terms of a proposed contract this means that economic theory should take into account that contract design includes bargaining between parties at some stage of the process when contract centralization and decentralization are compared to analyze this issue a very stylized model is used to examine the advantages of centralized and decentralized organizations two agents work jointly on a project for a principal usually in public procurement this is a contracting officer who represents a public agency

differential payments within a bidder coalition and the shapley value bidder coalitions at english auctions frequently distribute collusive gains among members via a secondary auction or knockout when coalition members are sufficiently heterogeneous nested coalition structures are observed in which a knockout is conducted at each level of nesting the nested knockout s characteristics are investigated within many settings we find that the expected payments to coalition members via the nested knockout equal the shapley value incentive compatibility problems of the nested knockout are also analyzed

decentralization hierarchies and incentives a mechanism design perspective separation of ownership from management multidivisional firm organizations delegation of production decisions to worker teams delegation of pricing and advertising decisions to retail franchisers reliance on intermediaries in trade or finance and distribution of regulatory authority across different agencies represent examples of organizations that delegate and distribute decision making authority instead of centralizing it this paper reviews literature on costs and benefits of delegated decision making in hierarchical organizations or contracting networks with regard to problems of incentives and coordination it starts by describing incentive and coordination costs of delegation in simple canonical examples of hierarchies where both information and incentives of different decisionmakers differ one class of models pertain to contexts where the classical revelation principle applies i e where costs of contractual complexity information processing or communication are absent agents do not collude and the mechanism designer can commit to the mechanism delegation may conceivably entail a loss of control and coordination arising from the divergence of information and incentives sufficient and necessary conditions for this loss to be mitigated entirely include risk neutrality top down contracting and monitoring of transfers or production assignments between subordinates the next class of models introduces communication costs that restrict the performance of centralized arrangements relative to delegation owing to a resulting loss of flexibility which has to be traded off against possible control losses of delegation finally consequences of collusion among agents is discussed which typically enlarge the range of circumstances under which delegation can attain optimal second best outcomes the paper concludes with a discussion of the relevance of this theoretical literature to recently emerging empirical studies of industrial organizations where delegated decision making plays an important role adoption of innovative human resource management practices new information technologies and retail franchising

aggregation determinacy and informational efficiency for a class of economies with asymmetric information abstract we identify and analyze a class of economies with asymmetric information that we call quasi complete for quasi complete economies we determine equilibrium trades show that the set of fully informative equilibria is a singleton and give necessary and sufficient conditions for the existence of partially informative equilibria besides unifying some familiar settings such as those of grossman 1976 and milgrom and stokey 1982 the following new results are proved a the same restrictions that deliver gorman aggregation under symmetric information are sufficient for gorman aggregation under asymmetric information even under partially informative prices b the traditional assumptions of quadratic utilities and endowment spanning that result in the capm under symmetric information deliver a conditional capm under asymmetric information with prices that need not be fully informative c the linear equilibrium in grossman s 1976 model is the only equilibrium linear or not while minor changes in the normality assumptions result in indeterminacy and partially informative equilibria and d if there is no aggregate endowment risk asymmetrically informed agents with common priors sell the risky part of their endowment in every equilibrium journal of economic literature classification numbers d82 g14 c62

all stage strong correlated equilibrium abstract a strong correlated equilibrium is a strategy profile that is immune to joint deviations different notions of strong correlated equilibria were defined in the literature one major difference among those definitions is the stage in which coalitions can plan a joint deviation before ex ante or after ex post the deviating players receive their part of the correlated profile in this paper we show that an ex ante strong correlated equilibrium is immune to deviations at all stages thus the set of ex ante strong correlated equilibria of moreno wooders games econ behav 17 1996 80 113 is included in all other sets of strong correlated equilibria

sophisticated sincerity voting over endogenous agendas the empirical findings on whether or not legislators vote strategically are mixed this is at least partly due to the fact that to establish any hypothesis on strategic voting legislators preferences need to be known and these are typically private data in this note it is shown that under complete information if decision making is by the amendment procedure and if the agenda is set endogenously then sophisticated strategic voting over the resulting agenda is observationally equivalent to sincere voting the voting strategies however are sophisticated this fact has direct implications for empirical work on sophisticated voting

government turnover in parliamentary democracies in this paper we consider a dynamic model of government formation and termination in parliamentary democracies that accounts for the following phenomena 1 cabinet terminations due to replacement or early election 2 cabinet reshuf es 3 minority and surplus governments 4 the relative instability of minority governments

a bargaining model of collective choice we present a general model of legislative bargaining in which the status quo is an arbitrary point in a multidimensional policy space in contrast to other bargaining models the status quo is not assumed to be bad and delay may be pareto efficient we prove existence of stationary equilibria the possibility of equilibrium delay depends on four factors risk aversion of the legislators the dimensionality of the policy space the voting rule and the possibility of transfers across districts if legislators are risk averse if there is more than one policy dimension and if voting is by majority rule for example then delay will almost never occur in one dimension delay is possible if and only if the status quo lies in the core of the voting rule and then it is the only possible outcome this core selection result yields a game theoretic foundation for the well known median voter theorem our comparative statics analysis yield two noteworthy insights i if the status quo is close to the core t hen equilibrium policy outcomes will also be close to the core a moderate status quo produces moderate policy outcomes and ii if legislators are patient then equilibrium proposals will be close to the core legislative patience leads to policy moderation

recognition without replacement in legislative bargaining abstract this paper studies infinite horizon sequential bargaining among n 3 players in which a proposer is randomly selected from the pool of potential proposers if the proposal is rejected the current and previous proposers are excluded from the pool of potential proposers and the game moves on to the next round until every player has had the same number of opportunities to be the proposer to analyze the model with a particular time dependency within each sequence of n rounds a cycle i characterize the stationary equilibrium of a stochastic game which i call cycle stationary subgame perfect cssp equilibrium the cssp equilibrium is unique in payoffs and analogous to the subgame perfect equilibrium of some forms of finite horizon bargaining even when every player is entirely patient the proposer s share in the cssp equilibrium is smaller than that predicted by the stationary equilibrium of the baron ferejohn legislative bargaining model

incentive schemes as a signaling device abstract this paper considers a model of moral hazard where the principal has private information for instance in an organizational setting the firm may be better informed about the profitability of a sales area for which it seeks to employ a new sales representative we show how this information asymmetry may lead to a game of signaling which can mute incentives

committees as substitutes for commitment in this article policies are negotiated in a committee by playing a dynamic voting game with an endogenous default or status quo policy i show that joining a committee by maintaining a strong agenda setting power is a way for a decision maker to commit to a policy that in absence of committees is not time consistent the disciplinary role of the endogenous status quo and the heterogeneity of preferences within the committee are two crucial ingredients to obtain this result as a motivating example this article focuses on the time consistency of monetary policy

interim third party selection in bargaining abstract third party intervention can reduce the risk of conflict in situations where the bargaining failure is due to asymmetric information in this paper i consider the selection of a third party in a two person bargaining problem where each disputant has private information about its relative strength or weakness for a class of problems i find that the disputants choose the third party that is best for the strong type but worst for the weak type due to the incentive of each disputant to avoid seeming weak to their adversary the selected third party s intervention entails a higher ex ante chance of conflict than intervention by any other alternative this paper shows how the process of interim third party selection can have important consequences for the outcome of a third party intervention in bargaining

dynamic collective choice with endogenous status quo we analyze a bargaining situation in which preferences evolve over time and the previous agreement becomes the next status quo the endogeneity of the status quo exacerbates the players conflict of interest players disagree more often than under exogenous status quo this leads to inefficiencies and status quo inertia under certain conditions the negotiations can come to a complete gridlock players never reach an agreement gridlock can occur between players with arbitrarily similar preferences provided they are sufficiently patient in legislative settings our model predicts polarization and explains why legislators may fail to react promptly to economic shocks

gifts as economic signals and social symbols gift giving has often puzzled economists especially because efficient gifts like cash or giving exactly what a person asks for seem crass or inappropriate it is shown in a formal game theoretic model that gifts serve as signals of a person s intentions about future investment in a relationship and inefficient gifts can be better signals other explanations for the inefficiency of gift giving are advanced and some stylized facts about gift giving practices are described many of which are consistent with the signaling view of gifts

collusion in organizations the principal agent theory developed in the 1980s has produced a large set of insights for understanding how contracts can be established within organizations this theory explains how a principal who offers a contract to an agent should structure this contract to overcome at least partially the asymmetries of information he faces by now optimal contracts with adverse selection or hidden knowledge with moral hazard or hidden action or with nonverifiability by a third party of some variables known ex post by both the principal and the agent are relatively well understood despite insightful extensions to multiagent or multiprincipal organizations this body of knowledge falls short of a comprehensive theory of organizations one major reason beyond the restrictive nature of the organizations studied lies in the noncooperative approach generally followed to model multiagent settings indeed in this standard paradigm the cooperation of agents desired by the principal can be induced by the contracts he offers to the agents each of them maximizing his own welfare given the behavior of the other agents what remains is that the principal has complete control of the game played by the agents unwanted communication or side contracting between agents can be prevented this is a rather unrealistic assumption contract theory teaches us that the principal structures the contracts so as to minimize the informational rents given up to the agents because of their informational advantages it is quite natural to expect a collective reaction on the part of the agents to protect their rents we need to understand how agents can react to the rules of an organization and beyond to understand how a principal who is aware of the incentives for collusion should design the organization modeling coalitional or collusive behavior and characterizing the regulatory responses to such behavior is a major task of organization theory the empirical relevance of this line of work is easy to establish a clear example is that of auctions for which the occurrence of cooperative behavior between bidders is a general and well documented phenomenon see porter and zona 1993

a theory of bureaucratization based on reciprocity and collusive behavior this paper addresses how an organization becomes a bureaucracy bureaucratization emerges from a self enforced norm of reciprocity between agents in an organization who exchange favors and promote subgoals which differ from the objective of the firm such collusive behavior becomes harder and harder to prevent over time as a result incentive schemes lose their flexibility and bureaucratization becomes a necessary equilibrium phenomenon in the long run the distribution of agents private information their preferences for the future and the force of the social norm of reciprocity are analyzed in terms of their effects on the long run behavior of the organization and on the speed of the bureaucratization process i introduction any theory of bureaucracy concerned with the analysis of the public sector or designed to understand the behavior of private organizations2 must find out why states and firms end up being more and more inefficient over time why organizations become routinized as they grow older and why unflexible rules unavoidably emerge in the long run in other words any theory of bureaucracy should also be accompanied by a theory of bureaucratization which could help us to understand organizations from a dynamic point of view following weber 1978 we hereafter define the bureaucratization of an organization as the process by which it adopts less flexible rules over time the aim of this paper is to explain this process in the case of the theory of the firm the formation of a dynamic theory of organizations has been on the research agenda at least since marshall who was the first to point out that old organizations and firms tend to decline over time first such

running against the status quo institutions for direct democracy referenda and allocations over time stylized institutions for direct democracy referenda are examined in a dynamic full information environment with myopic voters competitive agenda median voter processes are contrasted with monopolistic controlled agenda processes by extending existing static analyses to a class of dynamic institutions not previously characterized the status quo reversion rule this highlights the dependence of the progression of real equilibrium allocations over time on institutional structure by delineating the restrictions implied by each institutional form the model explains some persistent empirical regularities in particular a strict ceteris paribus ordering of the magnitudes of budgets by institutional form is derived for a wide portion of the parameter space

optimal robust bilateral trade risk neutrality a risk neutral seller and buyer with private information bargain over an indivisible item we prove that optimal robust bilateral trade mechanisms are payoff equivalent to non wasteful randomized posted prices

efficiency enhancing signalling in the samaritan s dilemma suppose an altruistic person a is willing to transfer resources to a second person b if b comes upon hard times if b anticipates that a will act in this manner b will save too little from both agents point of view this is the samaritan s dilemma this paper shows that the undersaving result is mitigated if we relax the standard assumption of complete information because if a is uncertain about how big b s need for support is b will have an incentive to signal that he is in great need by saving more than he otherwise would have done

commitment through renegotiation proof contracts with third parties the paper analyzes contracts as means of strategic commitment that is commitment against outside parties to the agreement it considers the example of an incumbent firm which enters a contractual relationship with its workers in order to deter entry it assumes away the possibility for the parties to precommit not to make pareto improving renegotiations of the agreement once entry has taken place under symmetric information the contract is thus found to be useless for entry deterrence if the incumbent firm or workers possess some private information excessive post entry production levels can however be sustained ex post since output reductions may not be incentive compatible while information asymmetries are usually welfare decreasing when the goal is optimal risk sharing they can thus be welfare improving for the contracting parties when commitment against outsiders is the goal of the contract the role of the renegotiation process as a constraint on sustainable agreements is stressed in the paper and the general relevance of strategic contractual commitment is discussed

the 2007 nobel memorial prize in mechanism design theory this paper provides an overview of mechanism design theory and explains the roles played by leonid hurwicz eric maskin and roger myerson in the development of this field

ex ante efficient ex post individually rational trade abstract consider a bilateral trade model with two sided incomplete information for a general set of independent beliefs an ex post individually rational mechanism generating the same level of ex ante expected gains from trade as an ex ante efficient interim individually rational mechanism is constructed thus imposing the stronger notion of ex post individual rationality on this mechanism design problem generates no loss of efficiency

the dynamic in efficiency of monetary policy by committee this paper develops a model where the value of the monetary policy instrument is selected by a heterogenous committee engaged in a dynamic voting game committee members differ in their institutional power and in certain states of nature they also differ in their preferred instrument value preference heterogeneity and concern for the future interact to generate decisions that are dynamically inefficient and inertial around the previously agreed instrument value this model endogenously generates autocorrelation in the policy variable and helps explain the empirical observation that the distribution of actual interest rate changes has a mode of zero

the endogenous transaction costs of delegated auditing abstract this paper analyzes the deadweight loss of delegated auditing in a three tier hierarchy in a costly state verification model this cost depends on the endogenous information structure the auditor s degree of risk aversion and the size of the punishment we identify the optimal contractual outcome of this delegation model with the solution obtained in a standard three tier hierarchical model of collusive auditor we then derive from this identification the set of parameters of the physical environment which may affect the efficiency of side contracting within the firm

do financial development urbanization and trade affect environmental quality evidence from china abstract it is of great significance to study the impact of financial development on carbon emissions for the development of low carbon economy although many empirical studies reveal significant correlations between financial development and various environmental pollution variables few studies differentiate financial scale and efficiency from other factors and pay attention to the impact of securities capital market on carbon emissions in view of the complexity of financial development impact mechanism on carbon emissions in china this paper classifies financial development into two dimensions financial scale and securities size we establish a broader autoregressive distributed lag error correction model ardl ecm which is used to measure the dynamic relationship among financial scale securities size urbanization economic development trade openness and china s carbon emission intensity the study indicates that there is positive short run and long run relationship among financial scale economic growth and carbon emission intensity this reflects that the current development of financial scale has stimulated the development of china s economy but brought carbon emissions the size of securities has a relatively small impact on carbon emission intensity both in the short run and long run this shows that china s current securities market mechanism of regulating carbon emissions needs further improvement the above conclusions are convinced by the robustness tests this paper provides empirical evidence for policy makers to support the implementation of financial and low carbon economy growth

can the theory of incentives explain decentralization this survey presents within a single model three theories of decentralization of decision making within organizations based on private information and incentives renegotiation collusion and limits on communication are three sufficient conditions for decentralization to be optimal cet article presente dans un cadre unifie un survol de trois theories de la decentralisation de la prise de decision dans les organisations ces theories reposent sur la presence d information privee et des incitations qui en decoulent la renegociation la collusion et les limites a la communication representent trois conditions suffisantes pouvant expliquer l optimalite de la decentralisation this abstract was borrowed from another version of this item

a model of farsighted voting i present a new method of interpreting voter preferences in settings where policy remains in effect until replaced by new legislation in such settings voters consider not only the utility they receive from a given policy today but also the utility they will receive from policies likely to replace that policy in the future the model can be used to characterize both long term preferences and distributions over policy outcomes in situations where policy is ongoing and voters are farsighted

does the size of the legislature affect the size of government evidence from two natural experiments this paper makes use of regression discontinuity designs to estimate the effect of the number of legislators on the size of government the results indicate a negative effect i e the larger the size of the legislature the smaller is the size of government this runs counter to conventional wisdom one potential explanation is that more legislators can better control a budget maximizing bureaucracy i present evidence that is consistent with the proposed mechanism

cooperation and punishment under repeated majority voting in light of the extensive theoretical evidence suggesting absence of equilibrium in voting models tullock 1981 asks why so much stability our results suggest the following answer political agents engaged in long term relationships can sustain highly stable allocations if there are strongly held norms for punishment of defectors 1

the equivalence of lending equilibria and signalling based insurance under asymmetric information i present a model in which a continuum of individuals have stochastic idiosyncratic income shocks complete insurance is physically feasible but unattainable due to an information asymmetry income shocks are observable only by the individuals receiving them any insurance institution must therefore rely on self reporting of income innovations two ways of achieving incentive compatible self reporting are presented the first is a debt market with an explicit lending restriction the second is an insurance contract that linearly filters a signal transmitted by individuals the two are then demonstrated to be identical equilibrium consumption fluctuates in a random walk which is inefficient given the physical potential for complete insurance but is efficient given the information constraints the results are complementary to those of green 1987 but permit more general stochastic processes of income to be analyzed serial correlation of income reduces the efficiency of the insurance

heterogeneous preferences and equilibrium trading volume abstract the representative agent lucas model stresses aggregate risk and hence does not allow us to study the impact of agents heterogeneity on the dynamics of equilibrium trading volume in this paper we investigate under what conditions non informational heterogeneity i e differences in preferences and endowments leads to nontrivial trading volume in equilibrium we present a non informational no trade theorem that provides necessary and sufficient conditions for zero equilibrium trading volume in a continuous time lucas market model with heterogeneous agents multiple goods and multiple securities we explain in detail how no trade equilibria are related to autarky equilibria portfolio autarky equilibria and peculiar financial market equilibria which play an important role in the literature on international risk sharing

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

signalling and renegotiation in contractual relationships this paper examines how the possibility of renegotiation affects contractual outcomes in signaling games when an infinite number of rounds of renegotiations are allowed before contracts are executed the main results of the paper are 1 contracts may still contain distortions 2 the popular efficient separating equilibrium outcome is never an equilibrium outcome with renegotiation 3 incentive compatibility constraints can be generalized to incorporate renegotiation 4 equilibrium outcomes can be separating and nevertheless depend on the uninformed player s prior and 5 renegotiation in signaling games may lead to outcomes similar to equilibrium outcomes of screening games in which multiple contract purchases are allowed copyright 1993 by the econometric society

reputational comparative advantage and multinational enterprise 1 introduction when cultivating a new export market or attempting to expand its share of an existing market an exporter is likely to find that it has been preceded by its reputation minus a readily identifiable brand name quality reputation may solely reflect the country of origin for example when consumers are presented with a large amount of complex product information they may use the country of origin as a heuristic in forming product impressions without considering other product attributes 1 in this article i show that this heuristic decision making process can affect a firm s quality decision and can therefore become self fulfilling hence any bias that consumers have may be well founded however it is only correct because firms respond rationally to it colombia s garment industry provides an interesting example of a self fulfilling unfavorable quality reputation in international trade as described by morawetz 1981 a single colombian garment firm took a contract for 50 000 men s suits that was beyond its capability the poor quality result so tarnished the american importer s name that other high quality importers become wary of colombian sewn garments with the payoff to high quality production reduced colombian garment firms then concentrated on low quality markets and the newly found unfavorable reputation was justified in the model constructed here consumers see only a noisy signal of the product s quality at the time of purchase therefore their posterior beliefs are based on this noisy signal and the country of origin reputations as will be made clear higher quality firms benefit more from an increase in their country s reputation so that a better reputation generates an increase in the percentage of high quality firms in this way the reputation becomes self fulfilling and ex ante identical countries can be correctly perceived as differing in their percentage of high quality producers i next introduce an economy with two sectors one sector produces more complex goods where high quality is not easily verified and is more essential to the product s performance these may be technology intensive products or they may consist of the design and marketing of the goods produced in the other sector in particular high quality production costs and the consumer s value for high quality goods is greater in this sector i show that this sector becomes more profitable as the country of origin reputation increases hence if one country s equilibrium reputation is low and the other country s equilibrium reputation is high then the pattern of specialization and international trade can be determined solely by reputational comparative advantage 2 finally i show that reputational comparative advantage can overshadow a small technological comparative disadvantage in determining the pattern of international trade given this pattern of trade and specialization based on reputational comparative advantage a high reputation firm may expend resources to establish a multinational enterprise mne in the low reputation country for example many mne products require the differing specializations of both the high and low reputation countries although differing in motivation this result accords well with more traditional models of vertical mne 3 however this impetus for mne as well as its more traditional counterparts does not explain why the mne would choose foreign direct investment fdi over a less costly licensing arrangement 4 the quality uncertainty in this model along with the difference in equilibrium reputations allows us to address this question in particular appropriable reputational rents are generated by fdi when the high reputation parent firm procures and internalizes production with a low reputation host firm this fdi breaks the low reputation equilibrium of the host firm and generates reputational rents

strategy proof stochastic assignment abstract i study strategy proof assignment mechanisms where the agents reveal their preference rankings over the available objects a stochastic mechanism returns lotteries over deterministic assignments and mechanisms are compared according to first order stochastic dominance i show that non wasteful strategy proof mechanisms are not dominated by strategy proof mechanisms however non wastefulness is highly restrictive when the mechanism involves randomization in fact the random priority mechanism i e the random serial dictatorship and a recently adopted school choice mechanism deferred acceptance with random tie breaking are wasteful i find that both these mechanisms are dominated by strategy proof mechanisms in general strategy proof improvement cannot be due to merely reshuffling objects and therefore must involve assigning more objects

coalition proof equilibrium we characterize the agreements that the players of a noncooperative game may reach when they can communicate prior to play but they cannot reach binding agreements a coalition proof equilibrium is a correlated strategy from which no coalition has an improving and self enforcing deviation we show that any correlated strategy whose support is contained in the set of actions that survive the iterated elimination of strictly dominated strategies and weakly pareto dominates every other correlated strategy whose support is contained in that set is a coalition proof equilibrium consequently the unique equilibrium of a dominance solvable game is coalition proof journal of economic literature classification

the organization of supplier networks effects of delegation and intermediation in a one principal two agent model with adverse selection and collusion among agents we show that delegating to one agent the right to subcontract with the other agent always earns lower profit for the principal compared with centralized contracting delegation to an intermediary is also not in the principal s interest if the agents supply substitutes it can be beneficial if the agents produce complements and the intermediary is well informed

communication complexity and mechanism design the curse of the revelation principle is that it leads us to focus on unrealistic mechanisms in which agents report all private information to the principal who then makes all decisions centrally this is not true when communication costs are introduced in that case partial communication of information sequential back and forth conversations and decentralization of decisions become part of optimal mechanisms this paper looks at the interplay between the incentive constraints and the communication constraints when can they be separated so that for example one can separately study the incentive compatibility of a social choice rule and the minimum cost communication protocol that realizes the social choice rule jel d82 c72

exergy analysis of the energy use in greece in this work an analysis is being done on the concept of energy and exergy utilization and an application to the residential and industrial sector of greece the energy and exergy flows over the period from 1990 to 2004 were taken into consideration this period was chosen based on the data reliability the energy and exergy efficiencies are calculated for the residential and industrial sectors and compared to the findings of a previous study concerning the exergy efficiency of the greek transport sector the residential energy and exergy efficiencies for the year 2003 were 22 36 and 20 92 respectively whereas the industrial energy and exergy efficiencies for the same year were 53 72 and 51 34 respectively the analysis of energy and exergy utilization determines the efficiency of the economy as a whole the results can play an important role in the establishment of efficiency standards of the energy use in various economy sectors these standards could be utilized by energy policy makers

a foundation for strategic agenda voting abstract we offer complete characterizations of the equilibrium outcomes of two prominent agenda voting institutions that are widely used in the democratic world the amendment also known as the anglo american procedure and the successive or equivalently the euro latin procedure our axiomatic approach provides a proper understanding of these voting institutions and allows comparisons between them and with other voting procedures

legislative bargaining with reconsideration we present a dynamic model of legislative bargaining with an endogenously evolving default policy and a persistent agenda setter policy making proceeds until the agenda setter can no longer pass a new policy to replace an approved bill we prove existence and necessary conditions of pure strategy stationary equilibria for any finite policy space any number of players and any preference profile in equilibrium the value of proposal power is limited compared to the case that disallows reconsideration as voters are induced to protect each other s benefits to maintain their future bargaining positions the agenda setter in turn would prefer to limit his ability to reconsider the lack of commitment due to the possibility of reconsideration however enhances policy efficiency

asymmetric information information externalities and efficiency the case of oil exploration in this article we examine the efect of private information and information externalities on the ex post eficiency of investment in oil exploration we show that too much drilling tends to occur ifjirms believe that the area is likely to contain a sizeable pool of oil and too little drilling occurs if the opposite is true bargaining with well defined property rights to the information externality can eliminate underinvestment but overinvestment remains a problem because firms have an incentive not to disclose their private information

stability with one sided incomplete information two notions of stability ex ante stability and bayesian stability are investigated in a matching model with non transferrable utility interdependent preferences and one sided incomplete information ex ante stable matching outcomes are unblocked for every belief on the blocking partner s type while bayesian stable matching outcomes are unblocked with respect to prior beliefs ex ante stability is a minimal requirement bayesian stability is a more selective desideratum with sound efficiency properties

agri environmental schemes adverse selection information structure and delegation this work analyzes alternative designs of agri environmental schemes and how different incentive mechanisms impact on their overall efficiency it focuses on spatial targeting and delegation in an asymmetric information context first the optimal contract under adverse selection is modeled this model underlines the trade off between information rents and allocative efficiency the impact of spatial targeting is then addressed disaggregated information structures increase the optimal efforts asked of the farmers it may also involve higher information rents and may reduce the net contributions of some farmers finally the consequences of delegating authority within the principal agent relationship are investigated the results illustrate that spatial targeting and delegation when combined have asymmetric impacts on farmers payoffs

dominant strategy implementation of bayesian incentive compatible allocation rules abstract a large literature on incentive mechanisms represents incentive constraints by the requirement that truthful reporting be a bayesian equilibrium this paper identifies mechanism design problems for which there is no loss in replacing bayesian incentive compatibility by the stronger requirement of dominant strategies we identify contexts where it is possible to change the transfer payments of an optimal bayesian mechanism so as to create dominant strategies and yet leave every participant s expected utility unchanged we also address the issue of multiple equilibria and unique implementation contexts where these results apply include auctions bilateral bargaining procurement contracting and intrafirm resource allocation

mandatory versus discretionary spending the status quo eect do mandatory spending programs such as medicare improve eciency we analyze a model with two parties allocating a xed budget to a public good and private transfers each period over an innite horizon we compare two institutions that dier in whether public good spending is discretionary or mandatory we model mandatory spending as an endogenous status quo since it is enacted by law and remains in eect until changed mandatory programs result in higher public good spending furthermore they ex ante pareto dominate discretionary programs when parties are patient persistence of power is low and polarization is low

auction design and favoritism abstract the theory of auctions has ignored the fact that often auction designers not the principal design auctions in a multi attribute auction the auction designer may bias his subjective evaluation of quality or distort the relative weights of the various attributes to favor a specific bidder an ancient concern in the procurement of weapons in the auctioning of government contracts and in the purchase of electricity by regulated power companies the paper analyzes the steps to be taken to reduce the possibility of favoritism it is first shown that in the absence of favoritism quality differentials among firms are more likely to be ignored if the auction designer has imperfect information about the firm s costs second if the auction designer may collude with only one bidder the other bidders should be chosen if they are at least as efficient as the former bidder and no hard information about quality differentials is released by the auction designer that would justify fair discrimination in favor of the former bidder last if the auction designer can collude with any bidder the optimal auction tends to a symmetric auction in which quality differentials are ignored the possibility of favoritism reduces the auction designer s discretion and makes the selection process focus on non manipulable monetary dimensions of bids

decentralized trading with private information the paper studies how asset prices are determined in a decentralized market with asymmetric information about asset values we consider an economy in which a large number of agents trade two assets in bilateral meetings a fraction of the agents has private information about the asset values we show that over time uninformed agents can elicit information from their trading partners by making small offers this form of experimentation allows the uninformed agents to acquire information as long as there are potential gains from trade in the economy as a consequence the economy converges to a pareto efficient allocation

virtual utility and the core for games with incomplete information abstract the core is extended to games with incomplete information the feasible set is characterized by incentive compatible mechanisms blocking is organized at the interim stage by an incentive compatible mediation plan membership of the blocking coalition itself may be determined randomly by the blocking mediator nonemptiness of an interim fine core is proven for games with a balanced structure independent types and sidepayments an offer of severance payments may be needed to inhibit blocking core allocations are characterized in terms of virtual utility scales that generalize the weighted utility scales of the inner core mechanisms that achieve core allocations are coalitionally durable

some unpleasant bargaining arithmetic abstract it is commonly believed that voting rules that are relatively more inclusive e g unanimity or supermajority are likely to yield relatively more equitable outcomes than simple majority rule we show that this is not necessarily the case in bargaining environments we study a multilateral bargaining model a la baron and ferejohn 1989 where players are heterogeneous with respect to the potential surplus they bring to the bargaining table we show that unanimity rule may generate equilibrium outcomes that are more unequal or less equitable than under majority rule in fact as players become relatively more patient we show that the more inclusive the voting rule the less equitable the equilibrium allocations

how a firm can induce legislators to adopt a bad policy this paper shows why a majority of legislators may vote for a policy that benefits a firm but harms all legislators the firm may induce legislators to support the policy by suggesting that it is more likely to invest in a district where voters or their representative support the policy in equilibrium no one vote may be decisive so each legislator who seeks the firm s investment votes for the policy though all legislators would be better off if they all voted against the policy and when votes reveal information about the district the firm s implicit promise or threat can be credible unlike influence mechanisms based on contributions or bribes the behavior considered is time consistent and in line with the low campaign contributions by special interests

sustainability analysis of a society based on exergy studies a case study of the island of samso denmark abstract the danish island samso has since 1997 initiated a process through which the island should reach a state where it would be able to supply its own energy such a situation was reached since 2005 after having established 21 windmills and the island is now a net exporter of electricity to the danish power network at the same time the buildings in the more habituated areas were connected to 4 district heating plants which generate heat from combustion of straw in some cases combined with supplementary inputs from photo thermal devices meanwhile certain activities on the island such as running the ferries cars factories and heating in more distant areas are still dependent on significant input of fossil fuels the inhabitants have recently stated a wish to move on towards being independent of fossil fuels in 2030 and carbon neutral during the next decades as a consequence the idea came up to develop a method for the sustainability analysis of a society which would assist in governing the transitional process in the direction of increasing sustainability therefore a framework has been developed based on the concept exergy that may reveal where large consumptions are taking places such areas are likely to be sensible targets for action or at least increased attention basic methods have been developed that allows to account for infrastructure transfers inputs and outputs and consumption in terms of exergy and taking into account whether the exergy storages or flows can be considered to be renewable or not the framework has been developed for six societal sectors the energy sector the public sector the private households the agricultural sector the industry commerce and trade sector and nature nature is here considered an activity that provides the society with an exergy that may also be of value to our societies often referred to as ecosystem services based on the estimated amount of infrastructure and transfers inputs and outputs a number of sustainability indicators have been developed that may be monitored over time and which may serve to indicate whether potential measures undertaken also lead the society in the right direction an attempt to evaluate the potential importance of wastes has also been carried out as in organic waste could play an important role in acquiring the amount of bio diesel required to run the ferries in the future the results demonstrate that the already existing overhead in production of electricity leaves the island with many options and a great opportunity to be independent of fossil fuels in near future in fact it might well be that socio economical perspectives will turn out to be the more severe obstacles in the transition process adjacent to this work a carbon model has also been set up to reveal the consequence of proposed measures and strategies to the carbon budget of the island jorgensen and nielsen 2014

delegation to encourage communication of problems we study a principal s choice to centralize or delegate decisions to an agent when delegation can be used to encourage the agent to communicate potential problems we find that the principal may choose centralization either to exercise better control over the agent s actions or to provide stronger incentives delegation emerges in equilibrium only if the costs of effort to acquire information for both the principal and the agent are sufficiently high we find that increases in the principal s penalties for an incorrect decision may increase the principal s expected payoff owing to optimal organizational responses in addition catastrophic risk the risk of incorrectly accepting a defective audit or product may be greater under centralization than under delegation furthermore catastrophic risk can be increased by well intentioned legislative efforts to decrease such risk by for example increasing the agent s penalties for failing to take a corrective action because the organizational structure may change
