models for referendum data the structure of discrete choice models for contingent valuation abstract in 1979 bishop and heberlein introduced an appealing variant of the contingent valuation method which required only yes or no responses hanemann developed a utility theoretic interpretation of the yes no responses which has helped popularize the approach recently cameron has offered another interpretation also utility theoretic which she argues is more general than the hanemann random utility model this paper compares the deterministic models suggested by hanemann and cameron showing them to be dual to each other it shows that correct specification of either function must exclude endogenous variables such as quantity demanded it also demonstrates that using utility theoretic models allows one to compare travel cost models and contigent valuation models on the basis of their implied behavior not on the unobservable surplus or variation measure

payments for pioneers revisiting the role of external rewards for sustainable innovation under heterogeneous motivations abstract acknowledging the diversity of preferences goals and motivations of individuals is key to promote the effectiveness of incentive based conservation interventions this paper analyses the heterogeneity of motivations to adopt silvopastoral practices a social ecological innovation for soil conservation and carbon emission reduction we use q methodology to identify smallholders views with regard to these practices in a community in the forest frontier in chiapas mexico the analysis uncovers three main perspectives self sufficient pioneers environmentally conscious followers and payment dependent conservatives we discuss these perspectives around three topics smallholders predisposition to adopt silvopastoral practices their views about needing external payments to sustain their livelihood and the diffusion of innovative sustainable practices we relate these perspectives with livelihood characteristics and with observed adoption levels under a pilot programme to promote silvopasture our findings suggest that incentives other than payments may be more appropriate for those more likely to adopt and that payments could encourage rent seeking strategies and not necessarily promote permanent behavioural change we suggest ways for designing more effective and adaptive environmental conservation programmes to foster adoption and continuation of social ecological innovations

agricultural support policies in imperfectly competitive markets why market power matters in policy design most agricultural policy analysis assumes that markets are perfectly competitive despite increasing evidence to the contrary we demonstrate that the interaction of market power and government intervention may lead to outcomes that are counter to key results of policy analysis for perfectly competitive markets we show that market power may reduce or eliminate entirely the net welfare benefits from removing two traditional support mechanisms price floors and deficiency payments and may increase considerably the government s cost of implementing either of them accordingly optimally designed price support measures may improve welfare in the presence of downstream oligopoly and or oligopsony power copyright 2011 oxford university press

sample selection individual heterogeneity and regional heterogeneity in valuing farmland conservation easements public concern about farmland loss has a long history these concerns are reflected in the u s federal farm bill and state level programs however studies of the benefits of farmland conservation have largely been conducted at the local level this study investigates heterogeneity in preferences for farmland conservation easements by conducting parallel studies in georgia maine and ohio and for a nationally representative sample using a choice experiment we find that a program set at the national level will not result in optimal allocations of funds at the state level in terms of targeting farmland that will generate the greatest public benefits

comparing tax and tax reallocation payments in financing rail noise abatement programmes results from a stated choice valuation study in italy the paper examines the use of stated choice experiments sc to assess the economic value of alternative rail noise reduction interventions on the brennero railway in italy the paper formally tests the econometric robustness of the sc estimates under three payment regimes a a regional tax where consumers must trade off welfare gains due to noise reduction for part of their income b a transport tax reallocation scheme where consumers must trade off a part of the tax payments that are currently spent on the public transport sector and c an administration tax reallocation scheme where consumers must trade off a part of the tax payments that are currently spent on the administration sector the test results are varied on the one hand the sc estimates are found to be statistically different for the tax reallocation and the tax introduction regimes this confirms previous valuation research results and thus reiterates the hypothesis that states the inequality between marginal values of private income and public money on the other hand the sc estimates are not found to be statistically different for the two proposed tax reallocation regimes suggesting that in the case study investigated here the marginal value of public money does not depend upon the budget source

incorporating stakeholder preferences for land conservation weights and measures in spatial mca abstract spatial multicriteria models may provide an equitable and efficient means for incorporating people s preferences in social decisions however in order for these tools to be effective they should include criteria that are locally relevant and measurable in a spatial framework this paper integrates measures of stakeholder preferences with gis data in a spatial multicriteria framework for identifying high priority areas for land conservation individual participants preference weights were measured using the analytical hierarchy process individual preferences were aggregated into groups representing outside experts and local stakeholders aggregate preferences differed across groups illustrating an affinity for local knowledge of stakeholders vs universal broader issues by outside experts the mapping of priority areas for conservation was relatively unaffected by the weights mostly due to the lack of spatial measures for locally relevant criteria

agricultural trade liberalization and economic development the role of downstream market power a model is developed to characterize the vertically linked and concentrated nature of developed country food markets this model is then parameterized and used to simulate the effects of varying food market structures on the benefits to developing country exporters of agricultural commodities from trade liberalization by developed countries results demonstrate that even relatively modest departures from perfect competition can cause much of the benefits from trade liberalization to flow to marketing firms instead of producers in the developing country the distributional effects under downstream market power differ significantly from the perfectly competitive case and may result somewhat paradoxically in developing countries receiving a lower share of the total value added within the food chain as trade reform occurs

specification of the logit model the case of valuation of nonmarket goods abstract we address the proper specification of the logit model for estimation of nonmarket commodity demand economic theory is used to show the conditions which must be met by the logit functional form if it is to yield valid estimates of welfare change measures and demand relationships an empirical example is used to illustrate the argument recreational boating data were collected using the contingent valuation method cvm in texas in one instance the demand curve is positively sloped due to the specific functional form chosen the estimated demand curve for the theoretically preferred functional form has the expected negative slope

a satisfactory benefit cost indicator from contingent valuation abstract standard economic concepts are used to develop a model of individual behavior when subject to the constraints of the contingent valuation choice context the model yields refutable consequences that are consistent with previously reported empirical findings including some that have been thought to be anomalous the model is used to show that different contingent valuation formats have predictably different performance characteristics notably the hicksian compensating measures are satisfactory benefit cost indicators when elicited using any one of several formats identified in the text of the formats examined one form of a policy referendum appears to have the most satisfactory characteristics overall we conclude that contingent valuation is a progressing research program

potential for private cost increasing technological innovation under a tax based economic incentive pollution control policy a criticism of the current pollution control policy is its lack of incentive for technological innovation the author argues that the implementation of a tax based economic incentive policy may have its pay off in terms of lower real control outlays but this makes it possible for total private compliance costs resource costs and tax or transfer costs to actually increase upon the introduction of some new less expensive control technologies he presents a numerical illustration of this phenomenon then derives the conditions under which such cost increases may occur cost increasing technological innovations could generally be avoided if the tax incentive is coupled with a net revenue lid for the pollution control authorities 4 references 3 tables

heterogeneous preferences and aggregation in environmental policy analysis a landfill siting case in many studies of nonmarket resources economists have data to disaggregate results according to subpopulations within the full study population disaggregated results can increase the usefulness of economic analyses improve public confidence in the results and permit public officials to assess equity concerns we outline an approach to obtain disaggregated results when characteristics of individuals may identify distinct preferences the approach is applied to public preferences regarding landfill siting decisions the discussion explores the implications of disaggregated results for policy decisions for bias in aggregate willingness to pay estimates and for nonmarket research methodologies

marginal property tax effects of conservation easements a vermont case study conservation easements allow landowners to transfer their land s development rights to another entity usually a nontaxable conservation organization conservation reduces the town s tax base necessitating a tax rate increase to maintain service levels however conserving land also decreases the supply of developable land and provides open space amenities that may be capitalized into the value of nearby properties these effects may offset the decrease in the tax base caused by the easement using a sample of twenty nine vermont towns we show that private conservation easements increase property tax rates in the short run but are tax neutral or tax suppressing in the long run

customer markets credit market imperfections and real price rigidity according to standard theory an increase in demand should raise prices of goods given factor prices empirically however prices appear to be unaffected by short run variations in demand this paper suggests an explanation of this observation if customers react slowly to price changes and credit markets are imperfect prices may be unchanged or even fall when demand increases the reason is that when demand is high profits are high and firms can compete more intensely for customers without increasing their borrowing copyright 1991 by the london school of economics and political science

an inferred valuation method although estimates of people s values for public goods are often needed to conduct cost benefit analysis existing value elicitation methods are prone to a number of well documented biases we argue that some of these biases result because people derive utility from the act of saying they are willing to pay for a good to counteract this phenomenon we consider an approach that asks people to predict or infer others values for a good instead of asking people to state their own value both a conceptual model and results from a laboratory experiment lend support for the new approach

a new paradigm for valuing non market goods using referendum data maximum likelihood estimation by censored logistic regression abstract this paper challenges the w m hanemann amer j agr econom 66 332 341 1984 and c sellar j p chavas and j r stoll j environ econom management 13 382 390 1986 utilizations of logit models to estimate the value of non market resources from referendum survey data these data are more informative than conventional choice data the random utility interpretation of logit models is therefore too restrictive bypassing the utility function entirely it will be shown that parameters and standard errors for utility theoretic inverse hicksian demand functions can be extracted directly and much more simply estimated demand functions need not be limited to those corresponding to the linear in parameters utility difference specifications which can be handled by packaged logit programs

measuring heterogeneous preferences for preserving farmland and open space abstract public preferences for environmental policies often vary among individual citizens according to their socio economic characteristics and attitudes toward environmental programs most researchers account for socio economic characteristics when conducting public preference surveys but do not account for differences in preferences that transcend socio economic categories identifying the public s attitudes regarding environmental programs and the role they play in shaping individuals preferences for policy alternatives can assist policy makers in developing programs that are consistent with public expectations this paper uses factor analysis and a discrete choice model to describe differences in public preferences that result from different attitudes regarding the goals of programs designed to preserve farmland and open space results describe policy implications that are not apparent when using models that address socio economic characteristics alone

explaining the swollen middle why most transactions are a mix of market and hierarchy why are firms sometimes more efficient than markets at organizing transactions why are most transactions arrayed neither at the pure market nor at the pure hierarchy end of the continuum but rather in the swollen middle incorporating features of both market and hierarchy why don t firms make greater use of price incentives this paper addresses these three questions by developing a model of the choice of institution one key building block is the distinction between organizing methods hierarchy and the price system and institutions firms and markets hierarchy and the price system are two distinct methods for organizing transactions each with particular costs and benefits markets and firms are institutions which use one or both of these methods although markets predominantly use prices and firms rely principally on hierarchy there is not a one to one correspondence between prices and markets or between hierarchy and firms indeed the paper argues that it is generally more efficient to use a mix of both methods than to specialize in either the paper focuses on the enforcement properties of prices and hierarchy hierarchy controls individuals directly by constraining their behavior by imposing behavior constraints while prices do it indirectly by measuring their outputs through price constraints under hierarchy individuals receive a salary to do as told while self employed individuals governed by the price system are rewarded on the basis of their output each system has its own biases using prices maximizes effort minimizes shirking but incites individuals to inflate the price and or reduce the quality of their output it encourages cheating relying on hierarchy results in the opposite bias under hierarchy individuals are not paid in function of their output but instead are rewarded for following directives they have thus strong incentives to minimize effort to shirk unless properly supervised but being paid a fixed sum to follow orders they have few incentives to cheat hence the price system experiences low shirking but potentially high cheating costs while hierarchy faces low cheating but high shirking costs organizing costs are the sum of shirking and cheating costs any given transaction will be organized by the mix of price and hierarchy i e by the mix of price and behavior constraints that minimizes organizing costs a transaction will be organized within a firm if the reduction in cheating costs achieved by replacing price constraints by behavior constraints exceeds the resulting increase in shirking costs and by the market in the opposite case the paper shows that cheating and shirking costs increase more than proportionately as one concentrates in either pure price or behavior constraints hence using a mix of both methods generally minimizes the sum of cheating and shirking costs this explains why most transactions exhibit features of both markets and hierarchy the paper shows clearly the tradeoff involved between price and behavior constraints it explains the costs and benefits of using two types of price incentives in firms piecework and profit centers and predicts when they will be used

unemployment behaviour evidence from the cps work experience survey this chapter is empirical and descriptive rather than theoretical it examines the cps unemployment experience data which gives the number of weeks of unemployment and the number of spells of unemployment experienced by a sample of people in a year this chapter focuses on both the entry rate or frequency probability of entering and the exit rate or duration probability of exiting of unemployment spells for it is on both the entry and exit rates that the level and distribution of unemployment depends the conclusion is that entry rates and differences in entry rates across people are of primary importance in explaining unemployment experience

using referendum data to characterize public support for purchasing development rights to farmland an econometric model that de scribes public support for farmland preservation programs as a function of local land use pat terns and socioeconomic data is developed two versions of the model are estimated using data from referenda conducted in pennsylvania and rhode island during 1982 through 1990 results suggest that support for referenda that purchase development rights is stronger in counties and towns with both rapidly increasing population and where land and house values have increased at higher rates environmental factors such as the prevalence of resource sensitive lands are also significant in describing the public s moti vation to preserve farmland jel q15

choices without prices without apologies valuing is usually regarded as a process of compressing information about attributes into a single metric armed with this reduced form of compact information the consumer can consider a particular object with a particular price attached or implied and make an informed decision but the process of valuing is less straightforward than we ordinarily suppose when environmental goods and services become the object of information compaction it is possible that important information is lost we comment on the choice problem germane to environmental goods and services and challenge the presumption that environmental choices made without explicit pricing are inferior to those in which hypothetical valuation studies are undertaken

changes in the cyclical pattern of real wages evidence from nine countries 1955 80 monetary policy in the united kingdom the monetarist vice has gripped the economy even longer and similar deflationary policies have been in effect in other western economies interestingly enough these policies were instituted in the context of a prolonged period of economic decline annual average rates of growth of gross domestic product for nine oecd countries fell from 6 8 to 5 o to 2 6 over the periods i955 66 i966 73 and i973 79 2 similarly unemployment has risen dramatically in the last io years the causes of slow growth and high unemployment are undoubtedly various however it is clear that restrictive macroeconomic policy has played an important role that is the recent situation is at least in part attributable to a deliberate effort to induce an economic slump the task of systematically examining the origins and motivations of this policy still awaits us however this paper presents an account of a general development in the pattern of real wages over the business cycle which is a plausible determinant of current policy the evidence indicates that short run cyclical movements in output no longer exert a determinate influence on real wage growth a development which may have been the impetus for long term deflation this account is based on an econometric study of nine countries over the period i955 80 the study has three noteworthy econometric features the first is that data from the nine countries are combined in a pooled model with homogeneous coefficients the use of a cross national sample ensures against the attribution of general theoretical status to particular empirical findings from a single country 3 second the units of observation are business cycle turning

the citizen versus consumer distinction an exploration of individuals preferences in contingent valuation studies abstract contingent valuation has been used extensively in estimating the value of environmental goods one criticism of this approach however is that respondents in referendum style contingent valuation surveys may express citizen assessments that take into account benefits to others rather than benefits that accrue purely to the respondent themselves within this context the aim of this paper is to examine to what extent individuals express different preferences when adopting a personal or a social citizen perspective while this paper provides some support for the hypothesis that individuals express different preferences when adopting collective as opposed to personal choices reported willingness to pay wtp was found to be insensitive to whether or not the respondents were asked the wtp question from a personal or social perspective

the numeraire matters in cost benefit analysis abstract the choice of numeraire is shown to be important in cost benefit analysis when a public good is involved individual consumers marginal rates of substitution will generally differ thus the less valuable the numeraire is to a person the higher the number required to express his net benefit and the more will his interest weigh in the total sum the choice of money as numeraire is systemetically favourable to those who value money the least relative to alternative numeraires

a comparison of compensating surplus and budget reallocation with opportunity costs specified the use of most nonmarket valuation techniques is predicated on respondents paying additional amounts of money for increased provision of a public good however in many circumstances this may not be appropriate treaty rights or the capacity of a government to raise and collect taxes in the context of a developing country may preclude the introduction of new taxes alternatively there may be settings where respondents reject the notion of an additional payment and a different approach to estimating nonmarket values is needed this article demonstrates a methodology for estimating compensating budget reallocation which is the amount of expenditure on other public goods that respondents are willing to forego for the government to provide more of another public good one of the main contributions of this article is a demonstration of how to improve the specification of the opportunity costs of budget reallocations second using choice modelling for the estimation of budget reallocations is compared with

public funding of environmental amenities contingent choices using new taxes or existing revenues for coastal land conservation alternative funding approaches affect stated preferences an individual s willingness to reallocate existing tax dollars exceeds willingness to pay new taxes to conserve land however stated preferences also imply a non zero opportunity cost to existing tax dollars different income groups reveal statistically equivalent marginal utilities both for income and for reallocating tax dollars yet individuals with lower income show a relatively larger increase in their willingness to support land conservation when the choice shifts from new taxes to reallocation of existing tax dollars the paper encourages consideration of equity implications that may be obscured when analysts focus on willingness to pay

estimating the market for tomatoes an econometric model of the market for tomatoes in israel is developed to take into account the distortions brought about by the marketing board and intermediaries the existence of monopoly and monopsony power is hypothesized by analyzing the middlemen s optimal behavior being compelled by the marketing board to purchase all produce wholesalers exert monopsony power by reducing quantities marketed to consumers by selling surpluses to the marketing board at the minimum price the empirical results confirm the existence of strong monopsony power together with weak monopoly power in that market

the anticipated real interest rate capital utilization and the cyclical pattern of real wages abstract this paper develops a channel through which increases in anticipated real interest rates can be expansionary for current aggregate labor demand and current output supply the key feature of the model is the introduction of a user cost of capital utilization which confronts the firm with the intertemporal problem of the optimal choices of capital utilization and depreciation the resulting variation in capital utilization and capital services in response to fluctuations in the real rate of interest shifts the marginal product of labor and thus the demand for labor at the same time and in the same direction that lucas rapping real interest rate effects operate on labor supply the complete model places no a priori restrictions on the cyclical pattern of real wages thus avoiding the countercyclical real wage prediction made by keynes and various classical writers that is rejected by the data estimates of a labor demand schedule for the annual u s data reveal a significantly positive real interest rate effect

evaluating impacts from noxious facilities including public preferences in current siting mechanisms abstract this paper describes an approach to facility siting that ranks potential sites in terms of their social impacts a contingent choice survey based on paired comparisons is used to construct a utility index to rank sites consistent with predicting results of a hypothetical referendum based on the attributes of the sites the method is likely to be acceptable to public decision makers since it is analogous to site scoring methods that have been commonly used indeed our approach is currently being employed as part of a larger landfill site selection process in the state of rhode island

causes of the current stagflation since 1975 labour slack has been unusually high in the oecd countries and yet inflation has not diminished the less favourable mix of unemployment and rate of change of inflation which we call stagflation is explained by a fall in the feasible rate of growth of real wages unmatched by a reduction in the constant term in phillips curve to investigate this mechanism conventional wage and price equations are estimated for 19 countries and then used for simulation stagflation has been caused in roughly equal amounts by rising relative import prices and by the fall in the rate of productivity growth in the basic model the phillips curve is assumed not to adapt to falls in feasible real wage growth but in a final section an adaptive wage equation is estimated which confirms that the process of adaptation is slow

why suicide terrorists get educated and what to do about it this paper tries to reconcile the observed fact that suicide terrorists have a relatively high education level with rationality it brings out the conditions under which potential students choose to acquire some education in a rational choice model where this yields a non zero probability of blowing up the resulting human capital in a terrorist attack the comparative statics of the rational expectations equilibrium of this model demonstrate how economic development on the one hand and repression on the other hand might reduce terrorism under some parameter restrictions

assessing public priorities for experiment station research contingent value and public preferences for agricultural research laws concerning government accountability mandate that agencies weigh constituent interests in setting priorities this study extends literature on the value of research by considering the public s stated preferences for scientist effort allocated across an agricultural experiment station s research portfolio over 75 of respondents expressed a willingness to pay exceeding 20 per household for allocations of at least 139 scientist months the mean household is willing to pay about 25 for a 25 increase in effort marginal analysis identifies topic areas where an additional scientist month provides above or below average benefits the distribution of effort across research topics significantly affects respondents values

real wage and real labour cost growth 1948 81 a disaggregated study the paper examines growth rates in labour cost and real wages for up to 38 separate uk industry categories this reveals much interesting information about labour markets which is ignored in most studies of the real wage the latter are mostly concerned with disequilibrium behaviour of the real wage the theoretical section of the paper explores the relationship between the growth rates in productivity real wages labour costs profit rates and value added prices relative to average prices under the assumption that factor markets are competitive the second section computes these respective growth rates and explores how well the competitive hypothesis stands up the results indicate reasonable agreement with the competitive thesis

amenity benefits and the optimal allocation of land agricultural land often yields sig nificant amenity benefits that may not be re flected in the prevailing allocation of land be tween agricultural and nonagricultural uses this paper introduces a simple supply demand model that incorporates these benefits in the de termination of optimal land allocation three stage least squares and county level data are used to estimate the supply and demand param eters these estimates confirm the plausibility of the conceptual model results from the con tingent valuation literature illustrate the extent of underallocation of land to agriculture due to existing institutional conditions some correc tive measures and their distributional effects are discussed and quantified jel q24

the effects of itq management on fishermen s welfare when the processing sector is imperfectly competitive in this paper we use a general model of imperfect competition to predict welfare changes within an open access fishery after it transitions to individual transferable quota itq management although related research has explored the effects of market power in the harvesting sector on itq performance none has considered the implications of an imperfectly competitive processing sector addressing this question we find that although fishermen should expect to gain from itqs under perfect competition they may suffer welfare losses if the processing sector is imperfectly competitive

the employment real wage relationship an international study the neoclassical and keynesian theories of employment both predict an inverse relationship between employment and real wages in the short run the observed correlation between employment and real wages however has usually failed to conform to this prediction dunlop 1938 and tarshis 1939 reported a positive correlation between real and money wages which given procyclical movement of money wages was interpreted as evidence against the theoretical prediction the statistical significance of these results was however challenged by ruggles 1940 and tobin 1948 more recent studies by kuh 1966 and bodkin 1969 failed to detect a significant relationship between real wages and employment these findings stimulated a series of contributions by solow and stiglitz 1968 barro and grossman 1971 1976 and others developing alternative models not apparently refuted by the evidence barro and grossman recast macro theory under the assumption that markets did not clear modigliani 1977 argued that the observed relationship between employment and real wages could be accounted for in an oligopolistic model of firm behavior thus both the competitive and equilibrium assumptions of the classical model were diagnosed as the sources of its apparent empirical refutation

valuing the multidimensional impacts of environmental policy theory and methods a theoretically consistent framework is developed for valuing the multidimensional impacts of environmental policy conventional benefit estimates are shown to be biased because of the presence of substitution and complementarity effects in valuing policy impacts procedures are developed for implementing a valid framework consistent with theory empirical results indicate significant substitution effects in valuing environmental conditions across different geographic regions

unemployment and the real wage the economic basis for contesting political ideologies using the keynesian theory of effective demand this paper demonstrates how particular models such as that of cooperative capitalism enunciated by the left keynesian social democrats the marxian model of profit squeeze emphasizing distributive conflict and even the conservative model relying on supply side stimulus fit in as particular variants of a more general theoretical scheme through a reconstruction of the familiar is schedule the argument is weaved around the theme of the relations between unemployment and real wage in the context of both a closed and an open economy to explain the common macroeconomic basis of contesting ideologies copyright 1990 by oxford university press

on the ideological foundations of environmental policy abstract this paper is an investigation into the philosophies of science inherent in the development of two schools of thought in environmental economics neoclassical and steady state analysis it attempts to gain clearer insight into the direction of inquiry and the policy options of each by contrasting their perspective metaeconomic structures the sets of first principles shaping theoretical development the ontology of steady state analysis while accepting the general principle of rationality differs from neoclassicism by including the ecological interaction of people with nature as an element of spicies being the cosmology of the two schools differs in the steady statists take the laws of thermodynamics and the principle of biospheric assimilation of first principles questions of absolute scarcity take primacy over the neoclassical focus on problems of relative scarcity in policy analysis consequently steady state theorists view the environment problem in its global dimensions over a longer time continuum the result is that steady state policy prescriptions are not necessarily market bound and may transcend the intstitutional arrangements common in western capitalist societies

choice experiments site similarity and benefits transfer choice experiments are designed to account for variations in environmental resources and site characteristics as well as potential implications of these variations for willingness to pay as a result choice experiment results may be well suited for benefits transfer it is unclear however whether the flexibility of choice experiments renders the similarity of study and transfer sites less critical for transfer validity drawing from identical choice experiments conducted in different rhode island communities this model assesses the extent to which error in function based benefits transfer is related to the similarity of communities across a variety of observable dimensions results suggest that site similarity at least across some dimensions influences the validity of choice experiment benefits transfers however the use of some measures of similarity as indicators of transfer error may provide misleading results

in search of a stylised fact do real wages exhibit a consistent pattern of cyclical variability the paper surveys the studies on the cyclical behaviour of real wages published from the twenties onwards the traditional simple neoclassical model of the labour market suggests that real wages tend to move countercyclically however from a theoretical viewpoint there are few reasons to expect this behaviour once the simple model is extended to account for imperfect competition uncertainty lagged responses or contracting between firms and workers empirical studies give different answers to the problem the contributions reviewed in the paper are arranged roughly in a chronological order the interwar period the postwar pre econometric studies the econometric work using aggregate data the evidence produced on the basis of longitudinal data the analyses of the shock responsiveness of real wages and finally the most recent papers attempting a reconciliation of the somewhat conflicting evidence derived from aggregate and panel data
