efficient mechanisms for bilateral trading we consider bargaining problems between one buyer and one seller for a single object the seller s valuation and the buyer s valuation for the object are assumed to be independent random variables and each individual s valuation is unknown to the other we characterize the set of allocation mechanisms that are bayesian incentive compatible and individually rational and show the general impossibility of ex post efficient mechanisms without outside subsidies for a wide class of problems we show how to compute mechanisms that maximize expected total gains from trade and mechanisms that can maximize a broker s expected profit journal of economic literature classification number 026

the environmental economic impact of woodland a two stage hedonic price model of the amenity value of forestry in britain woodland is an important part of the environment providing economic benefits through its use in commercial timber production and through its value as an amenity as well as providing recreation for visitors woodland is also important to local residents for whom it provides leisure opportunities and a source of aesthetic enjoyment it is well known that the price of a house may reflect a household s willingness to pay to live near an environmental amenity such as a forest and to gain access to it the nature of this relationship may be examined by applying the hedonic price technique an econometric method which investigates house prices and the variation in structural and environment characteristics over space this study uses a two stage hedonic price model to explore the impact of forest type on house price and to estimate the demand for broadleaved woodland for a sample of houses adjacent to forestry commission land

debt futures and options optimal price linked financial contracts under moral hazard and limited liability this paper characterizes the optimal financial contract between a risk neutral entrepreneur and risk neutral lender investors when the entrepreneur has limited liability there is moral hazard and the investor payoff function can depend on both output and output price but is nondecreasing in output in this setting the optimal contract is a price contingent commodity bond that can be replicated by combining pure debt commodity futures and commodity call option contracts although a pure commodity bond contract is sometimes optimal a pure debt contract is almost never optimal various properties of the entrepreneur s optimal price contingent promised payment are described copyright 1993 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

transaction costs in the theory of unemployment this paper addresses the problem of accounting theoretically for the persistence of large scale unemployment it briefly reviews some of the well known shortcomings of the keynesian account based upon sticky wages and prices and upon robert clower s 1965 concept of effective demand arguing that these shortcomings can be seen as a failure explicitly to integrate transaction costs into the theory of unemployment the main constructive contribution of the paper is an example of a simple macro model along the lines of robert barro and herschel grossman 1971 in which transaction costs are made explicit an essential part of this example is an externality of the sort suggested by peter diamond 1982 the example provides an account of persistent unemployment with many keynesian features yet without some of the keynesian shortcomings in particular it assumes perfect wage and price flexibility

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

meta analysis in model implementation choice sets and the valuation of air quality improvements this research illustrates how the methods developed for meta analysis can serve to document and summarize voluminous information derived from repeated sensitivity analyses our application is to the sensitivity of welfare estimates derived from discrete choice models to assumptions about the choice set these assumptions affect welfare estimates through both the estimated parameters of the model and conditional on the parameters the substitution among alternatives in our specific application the evaluation is in terms of estimated benefits of air quality improvements in los angeles based on discrete choices of neighborhood and housing copyright 2007 john wiley sons ltd

installed base and compatibility innovation product preannouncements and predation a good is often more valuable to any user the more others use compatible goods the authors show that this effect may inhibit innovation if an installed base exists and transition to a new standard must be gradual early adopters bear a disproportionate share of transient incompatibility costs this can produce excess inertia the installed base however is stranded if the new standard is adopted this may create excess momentum these dynamic effects have strategic implications temporary price cutting can permanently prevent entry and product preannouncements can be critical in innovation these strategic actions have ambiguous welfare effects

perquisites risk and capital structure in a corporate agency problem perquisites and risk interact to produce novel complex comparative statics for example even if additional debt induces risk neutral insiders to increase risk they never seek to increase the market value of their stock instead insiders decrease the present value of their subsequent conditionally optimal perquisites also the firm s optimal capital structure includes a risky bond with an agreement to remove insiders whenever the bond defaults however the optimal sharing rule between corporate claimants cannot be supported solely by standard securities such as bonds stocks options and their hybrids

what have we learned from three decades of research on the productivity of public capital the last three decades have witnessed a great deal of research effort devoted to measuring the private output elasticity of public capital the wide range of available estimates have precluded any consensus so far however this paper reconciles the empirical findings of the literature by quantitatively analyzing a sample of 578 estimates collected from 68 studies for the 1983 2008 period using meta regression analysis we show how study design characteristics and publication bias can explain a large fraction of the variation across estimates we find a short run output elasticity of public capital supplied at the central government level of 0 083 which increases to 0 122 in the long run if in addition only core infrastructure at a regional local level of government is considered these estimates are almost doubled the average output elasticity of public capital amounts to 0 106 our results suggest that public capital is undersupplied in oecd economies

on the resolution of agency problems by complex financial instruments a comment a convertible debt or b a package of external equity and managerial stock options ii the agency problems resulting from the shareholders incentive to bear unwanted risk also referred to as risk shifting can be resolved by issuing callable debt and iii welfare loss due to informational asymmetry between insiders and the market can be reduced by issuing callable debt in this paper we derive results that contradict these conclusions of bhs and hs we prove that convertible debt cannot costlessly resolve the agency problem due to excessive perquisite consumption farmer and winter 4 have recently shown that managerial stock options cannot resolve the problem we also show that convertible debt in general does not even mitigate this problem next we show that the argument that callable debt resolves agency problems due to risk shifting and informational asymmetry is incomplete the paper is organized as follows section i deals with the perquisite consumption problem section ii deals with both risk shifting and informational asymmetry problems since the basis of their resolution in the bhs argument is the same

are innovations relevant for consumers in the hospitality industry a hedonic approach for cuban hotels abstract this paper evaluates the impact of innovative activity in the hotel industry on the willingness to pay by consumers to this end we estimate a hedonic price function where innovation is identified indirectly through certain attributes that previous literature has linked with hotel innovativeness the test is performed on a representative sample of cuban hotels considering a large number of attributes of hotels and rooms to solve the usual problems of collinearity a million alternative models are estimated by choosing the variables included in a random manner and obtaining the final coefficients by means of an internal meta analysis the results are completed with a variance decomposition analysis the results highlight the importance of the attributes linked to innovation and internationalization on the determination of room prices in cuban hotels membership of international hotel chains high quality offers diversified rooms and adaptability to specific needs of each client

demand disturbances and aggregate fluctuations the implications of near rationality the paper investigates some properties of near rational models of the cycle examining two types of framework in the first an otherwise classical competitive economy is shown to respond to demand disturbances when some firms follow a near rational hiring policy in the second model a dynamic setting is addressed and a criterion termed stochastic near rationality is employed simulation results are consistent with recent empirical findings and suggest that further quantitative evaluation is merited copyright 1987 by royal economic society

estimating the implicit price of energy efficiency improvements in the residential housing market a hedonic approach abstract in this study a hedonic price model has been used to examine the impact which efficiency improvements have on housing values our study represents an improvement over a previous attempt to examine this issue in that the independent variable used in our analysis is designed to reflect variation in structural efficiency levels among sample homes rather than variation in occupant lifestyles and preferences in addition a flexible functional form is used to prevent bias due to misspecification of the hedonic price equation the study results reveal that efficiency improvements are capitalized into housing prices in des moines iowa at the average efficiency level of homes in the sample an efficiency improvement which results in a 1 decrease in the level of expenditures necessary to maintain the house at 65 f in the average heating season will increase the expected selling price of the house by 11 63 the premium obtained for an equivalent efficiency improvement will be greater than 11 63 in a relatively efficient home and less than 11 63 in a relatively inefficient home without further information concerning the price expectations and discount rates utilized by des moines home buyers and the average remaining life of fuels saving investments in the sample it cannot be determined whether the housing market is pricing fuel savings efficiently regardless of whether or not the implicit price of fuel savings is the outcome of an efficient market information on this implicit price facilitates the estimation of an average resale value of fuel saving investments in addition the results of this study refute the hypothesis that efficiency improving investments are not capitalized into housing prices

reputation and imperfect information abstract a common observation in the informal literature of economics and elsewhere is that is multistage games players may seek early in the game to acquire a reputation for being tough or benevolent or something else but this phenomenon is not observed in some formal game theoretic analyses of finite games such as selten s finitely repeated chain store game or in the finitely repeated prisoners dilemma we reexamine selten s model adding to it a small amount of imperfect or incomplete information about players payoffs and we find that this addition is sufficient to give rise to the reputation effect that one intuitively expects

predetermined prices and the persistent effects of money on output this note illustrates a model of predetermined pricing where firms set a fixed schedule of nominal prices at the time of price readjustment based on the work of fischer 1977 this contrasts with the model of fixed pricing the specification underlying most recent dynamic sticky price models it is well known that predetermined pricing cannot generate substantial persistence in the real effects of monetary shocks when prices are set via fixed duration contracts unless the contracts are of long duration however we show that with a probabilistic model of price adjustment a predetermined pricing specification can produce almost as much persistence as the more conventional model of fixed prices without the assumption of long average contract duration

after the big bang obstacles to the emergence of the rule of law in post communist societies when russia launched mass privatization it was widely believed that it would create a powerful constituency for the rule of law that didn t happen we present a dynamic equilibrium model of the political demand for the rule of law and show that beneficiaries of mass privatization may fail to demand the rule of law even if it is the pareto efficient rule of the game the reason is that uncertainty about the legal regime can lead to asset stripping and stripping can give agents an interest in prolonging the absence of the rule of law this abstract was borrowed from another version of this item

the impact of site characteristics on housing cost estimates abstract hedonic housing regressions using micro data for owners and renters from the 1972 1973 consumer expenditure survey are presented by including tract characteristics and public goods in these regressions evidence is presented which indicates sensitivity of the physical housing variable coefficients to the choice of included site related characteristics furthermore omission of public good variables can result in misleading and possibly perverse coefficients on access intermetropolitan housing cost estimates however are shown to be relatively insensitive to the choice of site related characteristics

sample selection and biases in local house value indices abstract analysis of cross sectional or intertemporal variations in house values among localities requires reliable house value indices however prior studies applying the hedonic method to transaction data have reported price series that may be biased our paper investigates a possible cause of bias and uses a censored regression technique extended to an intertemporal model to derive an unbiased index we apply our method to 1971 1991 data from the miami florida msa and find evidence in time varying amounts of bias our results suggest that prior studies using the hedonic method and samples consisting only of sold houses have understated the intertemporal variability of house prices

debt agency costs and industry equilibrium we show that risk characteristics of projects cash flows are endogenously determined by the investment decisions of all firms in an industry as a result in reasonable settings financial structures which create incentives to expropriate debtholders by increasing risk are shown not to reduce value in an industry equilibrium without taxes capital structure is irrelevant for individual firms despite its effect on the equityholders incentives but the maximum total amount of debt in the industry is determinate allowing for a corporate tax advantage of debt capital structure becomes relevant but firms are indifferent between distinct alternative debt levels the effect of firms financial structures on subsequent investment and output decisions has recently received considerable attention in the finance literature the central insight that equityholders control the firm s investment and production decisions and in general do not maximize the value of a levered firm has been applied to the analysis of risk shifting underinvestment and firms abilities to enter into optimal contracts with their customers existing models of firms financial structures and their effect on investment decisions are generally based on a single firm framework and do not take into account the relationship between project cash flows and the investment decisions of all firms in the industry 2 in this paper we allow the distribution of investment projects within an industry to adjust and show that this generates new insights and reverses several key results of single firm agency cost models the new predictions conform with well documented

technology adoption in the presence of network externalities we analyze technology adoption in industries where network externalities are significant the pattern of adoption depends on whether technologies are sponsored a sponsor is an entity that has property rights to the technology and hence is willing to make investments to promote it key findings include the following 1 compatibility tends to be undersupplied by the market but excessive standardization can occur 2 in the absence of sponsors the technology superior today has a strategic advantage and is likely to dominate the market 3 when one of two rival technologies is sponsored that technology has a strategic advantage and may be adopted even if it is inferior 4 when two competing technologies both are sponsored the technology that will be superior tomorrow has a strategic advantage

a review of innovation research in tourism abstract over the past two decades there has been increasing focus on the topic of innovation in tourism this article reviews the research contributions various categories of innovation product process managerial marketing and institutional are addressed important determinants of innovation are acknowledged including the role of entrepreneurship technology push and the existence of territorial industry clusters representation of knowledge is also identified as a critical factor for both the occurrence and nature of innovations the review reveals that there is still only limited systematic and comparable empirical evidence of the level of innovative activities and their impacts and wider implications for destinations and national economies an agenda for future research is emerging suggesting that there is quest for both formal quantification and for qualitative studies of the foundations processes implications and policies of innovation in tourism

the role of altruism in economic interaction abstract this paper considers environments in which the population consists of a mix of altruists and egoists and asks under what situations do altruists have a disproportionately large effect on equilibrium and under what situations is it the egoists we begin by presenting a general framework for answering this question we then apply the framework to the analysis of three economic environments 1 the classic problem referred to as the prisoner s dilemma 2 a world where agents decide whether or not to pollute the environment and 3 a world where agents decide whether or not to donate blood

the social selection of flexible and rigid agents people differ in how they respond to their environment some individuals treat each situation as unique and tailor their behavior accordingly while others respond in the same manner regardless of the situation the authors objective is to explore how social systems select from such a heterogeneous population a class of simple hierarchical systems is considered which encompasses some features of corporations and electoral systems a selection process operates on this population which results in successful agents going on to compete against equally successful agents for further advancement the author characterizes the population dynamics and the type of agent that ultimately dominates copyright 1998 by american economic association

predation reputation and entry deterrence abstract economists often argue that predatory practices are irrational since there exist cheaper or more certain means to gain or maintain a monopoly our gametheoretic equilibrium analysis suggests that if a firm is threatened by several potential entrants then predation may be rational against early entrants even if it is costly when viewed in isolation because it yields a reputation which deters other entrants asymmetric information plays a crucial role in our analysis since it provides the rationale for entrants to base their expectations of the firm s future behavior on its past actions the analysis also suggests methods to treat general reputational phenomena

towards a theory of innovation in services abstract the paper sets out some foundations for a theory of innovation in service industries and indicates the role that such innovation may play in the generation of growth cycles the discussion starts with the origins of a major new technology in the capital goods sector and its subsequent development according to the normal product cycle theory this is followed by a consideration of the transmission process by which the new technology is taken up in user industries within the consumer goods and services sector a reverse product cycle is then proposed to describe the innovation process which takes place in user industries such as services once the new technology has been adopted this cycle starts with process improvements to increase the efficiency of delivery of existing services moves on to process innovations which improve service quality and then leads to product innovations through the generation of new types of services finally the existence of two out of phase innovation cycles in the capital and consumer sectors deriving from a technology transmission process which causes disequilibrium in technical progress between the two is put forward as a mechanisms helping to create the long wave fluctuations in economic development associated with schumpeterian technological revolutions

buying beauty on prices and returns in the art market this paper investigates the price determinants and investment performance of art we apply a hedonic regression analysis to a new data set of more than one million auction transactions of paintings and works on paper based on the resulting price index we conclude that art has appreciated in value by a moderate 3 97 per year in real u s dollar terms between 1957 and 2007 this is a performance similar to that of corporate bonds at much higher risk a repeat sales regression on a subset of the data demonstrates the robustness of our index next quantile regressions document larger average price appreciations and higher volatilities in more expensive price brackets we also find variation in historical returns across mediums and movements finally we show that measures of high income consumer confidence and art market sentiment predict art price trends this paper was accepted by wei xiong finance

monetary non neutrality in a multisector menu cost model empirical evidence suggests that as much as one third of the u s business cycle is due to nominal shocks we calibrate a multisector menu cost model using new evidence on the cross sectional distribution of the frequency and size of price changes in the u s economy we augment the model to incorporate intermediate inputs we show that the introduction of heterogeneity in the frequency of price change triples the degree of monetary non neutrality generated by the model we furthermore show that the introduction of intermediate inputs raises the degree of monetary non neutrality by another factor of three without adversely affecting the model s ability to match the large average size of price changes a single sector model with a frequency of price change equal to the median rather than the mean generates monetary non neutrality similar to that in our multisector model our multisector model with intermediate inputs generates variation in real output in response to calibrated aggregate nominal shocks that can account for roughly 23 of the u s business cycle

honesty in a regulatory context good thing or bad abstract it is often taken for granted that if more firms were innately honest or ethical this would be a good thing we use the example of pollution policy to dispute such a claim if regulation is by pollution tax social welfare is non monotonic in population honesty the choice of policy instrument may itself be characterised by reversals with command and control methods being preferred for intermediate values of population honesty a tax system being preferred at the extremes this means that if because of the spread of ethical shareholding or for whatever reason the honesty of the corporate population increases through time we should not be surprised to see at first a switch away from market based instruments and then a switch back though environmental regulation is chosen as a context the implications are more general

efficiency wage models of unemployment keynesian economists hold it to be self evident that business cycles are characterized by involuntary unemployment but construction of a model of the cycle with involuntary unemployment faces the obvious difficulty of explaining why the labor market does not clear involuntarily unemployed people by definition want to work at less than the going wage rate why don t firms cut wages thereby increasing profits

bounded rationality and strategic complementarity in a macroeconomic model policy effects persistence and multipliers motivated by recent developments in the bounded rationality and strategic complementarity literatures we examine an intentionally simple and stylized aggregative economic model when the assumptions of fully rational expectations and no strategic interactions are relaxed we show that small deviations from rational expectations taken alone lead only to small deviations from classical policy ineffectiveness but that the situation can change dramatically when strategic complementarity is introduced strategic complementarity magnifies the effects of even small departures from rational expectations producing equilibria with policy effectiveness output persistence and multiplier effects

aggregation and linearity in the provision of intertemporal incentives we consider the problem of providing incentives over time for an agent with constant absolute risk aversion the optimal compensation scheme is found to be a linear function of a vector of n accounts which count the number of times that each of the n kinds of observable events occurs the number n is independent of the number of time periods so the accounts may entail substantial aggregation in a continuous time version of the problem the agent controls the drift rate of a vector of accounts that is subject to frequent small random fluctuations the solution is as if the problem were the static one in which the agent controls only the mean of a multivariate normal distribution and the principal is constrained to use a linear compensation rule if the principal can observe only coarser linear aggregates such as revenues costs or profits the optimal compensation scheme is then a linear function of those aggregates the combination of exponential utility normal distributions and linear compensation schemes makes computations and comparative statics easy to do as we illustrate we interpret our linearity results as deriving in part from the richness of the agent s strategy space which makes it possible for the agent to undermine and exploit complicated nonlinear functions of the accounting aggregates

investment incentives debt and warrants abstract this paper models and characterizes investment incentive problems associated with debt financing the decision problem of residual claimants is explicity formulated and their investment policies are characterized the paper also analyzes the use of conversion features and warrants to control distortionary incentives these claims reverse the convex shape of levered equity over the upper range of the firm s earnings and this mitigates the incentive to take risk it is shown that under certain conditions such claims can be constructed to restore net present value maximizing incentives and simultaneously meet the financing requirements of the firm

attributes determining condominium prices in bangkok in thai the housing market particularly the condominium sector in bangkok has been rapidly expanding in this paper the hedonic price model is used to analyze the housing attributes that determine the price of condominiums in bangkok the box cox technique is used to find an appropriate functional form of the model the data of condominium prices and 20 attributes of 146 condominium units were collected from 42 sales offices during 1 31 january 2011 the results indicate that the attributes determining the price of condominium in bangkok were project location proximity to sky train and subway unit location unit size furniture total number of units in a project land size waiting duration before construction is completed reputation of developers parking space common fee for maintenance and services and number of bedrooms the estimated coefficients indicate relative prices of the attributes which can be used as reference prices for buyers developers and banks

responders versus non responders a new perspective on heterogeneity this paper considers the implications of a particular type of heterogeneity one which characterizes a large number of economic environments but that has not received any systematic treatment in the literature the authors refer to this heterogeneity as responders versus nonresponders the paper begins by providing a general framework for the analysis of environments characterized by this heterogeneity and then shows how this framework can be used to help understand a wide variety of economic environments particular applications considered are near rationality network externalities and models of reputation copyright 1991 by royal economic society

strategic interaction among heterogeneous price setters in an estimated dsge model abstract we consider a dynamic stochastic general equilibrium model dsge in which firms follow one of four price setting regimes sticky prices sticky information rule of thumb or full information flexible prices the parameters of the model including the fraction of each type of firm are estimated by matching the moments of the observed variables of the model to those found in the data we find that sticky price firms and sticky information firms jointly account for over 80 of firms in the model we compare the performance of our hybrid model to pure sticky price and sticky information models along various dimensions including monetary policy implications

an analysis of the principal agent problem most analyses of the principal agent problem assume that the principal chooses an incentive scheme to maximize expected utility subject to the agent s utility being at a stationary point an important paper of mirrlees has shown that this approach is generally invalid we present an alternative procedure if the agent s preferences over income lotteries are independent of action we show that the optimal way of implementing an action by the agent can be found by solving a convex programming problem we use this to characterize the optimal incentive scheme and to analyze the determinants of the seriousness of an incentive problem
