two stage bargaining with coverage extension in a dual labour market abstract this paper studies coverage extension in a simple general equilibrium model with a dual labour market the union sector is characterized by two stage bargaining whereas the firms set wages in the non union sector in this model firms and unions of the union sector have a commonality of interest in extending coverage of a minimum wage to the non union sector furthermore the union sector does not seek to increase the non union wage to a level above the market clearing wage in fact it is optimal for the union sector to impose a market clearing wage on the non union sector finally coverage extension increases welfare in this model

sectoral shocks and aggregate fluctuations abstract this paper presents a multisector dynamic general equilibrium model of business cycles with a distinctive feature aggregate fluctuations are driven by independent sectoral shocks the model hypothesizes that trade among sectors provides a strong synchronization mechanism for these shocks due to the limited but locally intense interaction that is characteristic of such input trade flows limited interaction characterized by a sparse intermediate input use matrix reduces substitution possibilities among intermediate inputs which strengthens comovement in sectoral value added and leads to a postponement of the law of large numbers in the variance of aggregate value added the chief virtue of this model is that reliance on implausible aggregate shocks is not necessary to capture the qualitative features of macroeconomic fluctuations building on horvath 1998 review of economic dynamics 1 781 808 which establishes the theoretical foundation for the relevance of limited interaction in the context of a stylized multisector model this paper specifies a more general multisector model calibrated to the us 2 digit standard industrial code economy simulations prove the model is able to match empirical reality as closely as standard one sector business cycle models without relying on aggregate shocks

cost function estimation under risk aversion standard definitions of the cost function do not admit risk standard ex post approaches to cost function estimation yield biased and inconsistent estimates when production is stochastic recently an ex ante approach to cost function estimation with stochastic production has been developed by imbedding the distance function in the cost function estimation problem we generalize the approach to consider risk aversion in decision making only two empirical studies have considered stochastic production in cost function estimation both have required constant returns to scale we demonstrate a methodology sufficiently general to consider nonconstant returns to scale

incorporating stochastic variables in crop response models implications for fertilization decisions most crop decision models focus on output variation in response to nonstochastic inputs little attention has been given to the effects of stochastic factors on the input use decision a crop decision model is developed to examine the impact of soil moisture on the nitrogen fertilization decision the model is applied to 15 different soil and weather conditions for corn production in indiana based on estimated response functions the profit maximizing nitrogen application rate varies from 156 to 185 pounds of actual nitrogen n per acre we evaluate the expected economic losses arising from applying to one set of conditions a rate deemed optimal for another

acreage decisions under risk the case of corn and soybeans an acreage supply response model is developed under expected utility maximization the resulting framework is used to specify and estimate a system of risk responsive acreage equations for corn and soybeans in the united states particular attention is given to the truncation effects of government price supports on the distribution of corn and soybean prices also a wealth variable is included in the acreage equations the empirical results indicate that risk and wealth variables play an important role in cornsoybean acreage decisions the analysis also shows that cross commodity risk reduction is important in acreage allocation decisions

nominal and real wage cyclicality during the interwar period although there have been numerous attempts to study the cyclicality of real wages in the u s no consensus has formed as to the implications of the various findings for business cycle theory this paper will demonstrate that separating the real wage into its nominal and price level components can shed new light on the interwar u s labor market more specifically we will show that an evolution from a relatively laissez faire labor market during the 1920s to a more highly regulated labor market during the 1930s may have resulted in a more countercyclical real wage rate if we could be certain that equilibrium business cycle models provided the correct specification of the labor market then interpretation of real wage cyclicality would be relatively straightforward during periods dominated by labor demand shocks real wages would move procyclically and during periods dominated by labor supply shocks real wages would move countercyclically in a disequilibrium model context however interpretation of real wage cyclicality is much more problematic if nominal wages are sticky then unanticipated price level changes can induce countercyclical real wage movements that mimic the real wage movements generated by shifts in the supply of labor perhaps the most famous and controversial example occurred during the first three years of the great depression when a massive decline in hours worked and production was associated with a sharp increase in the aggregate real wage rate see figure 1 even greater complexity results from governmental attempts to influence the aggregate nominal wage policies that attempt to artificially change the nominal wage rate can result in either procyclical or countercyclical real wages depending on whether the direct impact of changes in the price of labor on the quantity of labor demanded outweighs the impact of wage changes on aggregate demand and output separating the aggregate real wage rate into its nominal and price level components will allow us to discriminate between these two hypotheses if labor markets are correctly characterized by equilibrium models then the price level and real wage are determined independently and separating the real wage into its nominal and price

can training and employment subsidies combat european unemployment active policy evaluation problems methods and results european countries with poorly performing labour markets and labour market institutions conducive to high unemployment also feature considerable expenditures on active labour market policy and such policies are emphasized by the european union s employment strategy however the practice of these programmes evaluation is much less well developed in europe than in the united states we outline key issues facing such evaluation and offer a review and formal assessment of european evaluation studies over the last three decades we find that programme effects are very heterogeneous across types of interventions and target groups that training and job search assistance can be effective and that the young among the unemployed are typically difficult to assist jochen kluve and christoph m schmidt

on the absence of positive wage indexation this paper rationalizes the absence of positive wage indexation in labour contracts that is of indexing provisions that link wage increases to inflation we investigate the equilibrium of a policy game in a stochastic economy in which wage setters and a policy maker interact strategically in order to determine the preferred degree of wage indexation and an optimal stabilization rule respectively our conclusion is that nominal wage rigidity and counterinflationary economic policy represent the best courses of action when price stability is valued and negative responses of contractual wages to price shocks are ruled out under these assumptions moreover the stochastic structure of the economy has no bearing on the optimality of maximal real wage flexibility this paper presents an argument for explaining nominal wage rigidity in labour contracts we investigate the equilibrium of a policy game in a stochastic economy in which wage setters and a policy maker interact strategically in order to determine the preferred degree of wage indexation and an optimal intervention rule respectively our conclusion is that indexing provisions that maximize the flexibility of real wages and counter inflationary economic policy represent the best courses of action for the players in the absence of schemes that create a negative correlation between wage and price movements maximal real wage flexibility is attainable through zero indexation or rigid nominal wages the crucial assumption that drives this result is that some price stability is desirable for the policy maker the introduction of price stability as a goal seems eminently justified from a practical standpoint the federal reserve system s legislative mandate from the federal reserve reform act of 1977 the ongoing debate about the house joint resolution 409 and the delors report which speaks of an unequivocal commitment to maintain price stability as the primary objective of the european system of central banks

policy effectiveness in an open multi market economy with risk neutral exchange rate speculation abstract in an open multi market equilibrium model of the business cycle the informational role of a forward exchange market is that the forward rate aggregates individual perceptions of the aggregate state of the economy in the case of risk neutral exchange rate speculation the forward rate perfectly reveals average expectations of current nominal shocks that hit the economy this paper analyzes the informational implications of forward speculation when markets are structurally diverse the two types of structural diversity considered are heterogeneous price elasticities of output demand and supply and asymmetric information between traders in output markets and traders in asset markets in contrast to previous results the paper shows that risk neutral speculation is not in general sufficient to generate a fully revealing rational expectations equilibrium in which monetary policy is ineffective

business cycle models with endogenous technology this paper compares real and monetary business cycle models with and without endogenous technical change if technology is endogenous the properties of these models change significantly in particular both real and monetary models yield very similar output processes if growth is endogenous and changes in aggregate demand can result in permanent changes in productivity employment and output the effect of depreciation of technology is examined and the pattern of real wage movements over the cycle when money wages are fixed but technology is changing is briefly considered copyright 1990 by american economic association

globalization regionalism and labour markets should we recast the foundations of the eu regime in matters of regional rural and urban development globalization has been accused of being the source of many problems some claim that this would justify a fundamental change of the eu regime that takes international competitiveness of the economy as its point of departure this would have consequences for the present set up of the eu cohesion regime and thus also for the policy toolkits of individual regions the article analyses the effects of globalization and regionalism on labour markets it does so on the basis of an extensive review of the theoretical and empirical literature covering various strands of thought the survey shows that fears about negative effects are not justified provided a consistent set of policies is pursued so the review does not support claims for a change of the eu regime neither in matters of the macro aspects nor in matters of regional development and cohesion

sticky prices as coordination failure this paper links the coordination failure and menu cost approaches to the microeconomic foundations of keynesian macroeconomics if a firm s desired price is increasing in others prices then the gain from price adjustment after a nominal shock is greater if others adjust this strategic complementarity leads to multiple equilibria in the degree of rigidity welfare may be much higher in the equilibria with less rigidity thus nominal rigidity arises from a failure to coordinate price changes jel e12 e30 keynesian macroeconomics waned in the 1970 s because economists grew disenchanted with its weak microeconomic foundations the central difficulty was that keynesian models were based on ad hoc rigidities in nominal wages and prices the 1980 s produced two approaches to reviving keynesian theory the menu cost literature n gregory mankiw 1985 george akerlof and janet yellen 1985 seeks to provide rigorous explanations for nominal rigidities these papers argue that small frictions in price setting are enough to produce large nominal rigidities in contrast the coordination failure literature russell cooper and andrew john 1988 abandons nominal rigidities and seeks alternative foundations for keynesian models the central idea is that many economic activities such as production e g john bryant 1983 trade e g peter diamond 1982 and investment e g nobuhiro kiyotaki 1988 exhibit synergism or strategic complementarity one agent s optimal level of activity depends positively on others activity strategic complementarity can lead to multiple equilibria with high activity equilibria superior to low activity equilibria thus an economy may be stuck in an underemployment equilibrium even though a superior equilibrium exists models with nominal rigidities and models with coordination failures are often presented as competing paradigms 1 this paper shows that this view is incorrect we take a step toward unifying the foundations of keynesian economics by showing that the two sets of ideas are highly complementary nominal rigidity arises from a failure to coordinate price changes this failure has the essential features of coordination failures in previous models flexibility in one firm s price increases the incentives for other firms to make their prices flexible this strategic complementarity leads to multiple equilibria in the degree of nominal rigidity equilibria with less rigidity more active price adjustment are often pareto superior to equilibria with more rigidity these results contribute to our understanding both of coordination failure and of nominal rigidity the range of keynesian phenomena explained by coordination failures is greatly expanded previous coordination failure models contain only real variables and thus ascribe no role to monetary policy or other determinants of nominal spending our results suggest that coordination failure is at the root of inefficient nonneutralities of money theories of nominal rigidities gain new empirical and policy im

the economic impact of minimum wages in europe opponents of minimum wages argue that they hurt jobs in europe supporters say that they combat exploitation and help the poor we try to sort out myth from reality differing policy prescriptions reflect different views of how the labour market actually works contrary to popular wisdom it is as easy to make a theoretical case against minimum wages as for them evidence not theory is what is needed now relative to average wages minimum wages have not risen in europe over the last 30 years they caused higher unemployment only if they prevented a necessary fall in the wages of the low paid second minimum wages for young workers are often a lower proportion of average earnings in europe than in the usa third we find no general evidence that minimum wages reduced employment except perhaps for young workers the good or bad effect of minimum wages has been exaggerated

supply demand and technology in a multiproduct industry texas field crops the purpose of this paper is to examine the structure of agricultural production for six texas field crops cotton grain sorghum wheat corn rice and hay which account for nearly 95 of recent field crop value specific objectives are to a test the structure of technology to determine i if output and input utilization choices for individual products are independent of production decisions about other outputs and ii if products and or inputs can be consistently aggregated b estimate a coherent set of interrelated supply functions for the six commodities and input demand functions for fertilizer and hired labor because the empirical focus of this paper is specific to one state the results will be of limited value for interpreting specific production relationships elsewhere however the problem is of common interest in production agriculture and the techniques used demonstrate an important application of dual modeling

cross country evidence on labor market institutions and young adult employment through the financial crisis i develop and analyze a set of cross country facts regarding employment and wage setting institutions over the decade surrounding the 2008 financial crisis among long industrialized countries young adult employment declined more than prime age employment over this time period i show that differences in countries wage setting institutions strongly predict variations in the magnitude of declines in young adult employment both unconditionally and conditional on changes in macroeconomic conditions young adult employment declined 5 percentage points less in countries where wage setting is driven by collective bargaining arrangements than in countries with statutory wage floors evidence on the evolution of legislated minimum wage rates and of an asymmetry in the relationship between growth and young adult employment suggest an important role for a standard wage rigidity mechanism

econometric estimation of producers risk attitudes general methods are proposed for the identification and econometric estimation of the parameters of the distribution of risk attitudes in a producer population the proposed methods also provide the basis for the development of statistical tests of model specification and of behavioral hypotheses econometric risk attitude estimation is shown to be possible under less restrictive conditions than previously believed a moment based version of the general model is applied to indian data and the econometrically estimated risk attitudes are presented and compared to experimental results for a similar group of producers

disequilibrium dynamics with inventories and anticipatory price setting this paper studies the sequence of short run quantity constrained equilibria of a model with a single storable output labor and money the durability of output gives rise to inventory fluctuations which influence the course of the equilibria attained one special feature of interest is the assumption that prices are not at the level which would equilibrate all markets if there were no stochastic shocks to the economy with prices frozen at this level the nature of the realized shocks determines the type of disequilibrium realized and the unintended component of inventory change the analysis concentrates on two questions what is the statistical nature of the process governing the real wage output employment and inventories and is it possible to test this model against the alternative hypothesis that prices are continually flexible even after the shocks have disturbed the system we find that although these theories are similar in their qualitative structure tests can be developed we also show how the frequencies of different types of quantity constrained equilibria vary with the stochastic specification this may shed some insight on why it is commonly believed that some types of disequilibrium phenomena have not been observed this abstract was borrowed from another version of this item

the relevance of unanticipated money growth in explaining output variation this paper tests a reduced form equation in which real gnp for the united states is explained by deviations of multi period m1 growth rates from ex ante expectations of those rates formed from one to eight quarters earlier the theoretical model is suggested by stanley fischer s 1977 article and may be thought of as a new keynesian model the equations are tested in both level and first difference specifications to allow for possible unit roots empirical results strongly support this model in preference to new classical and keynesian alternatives ex ante expectations or m1 growth are formed from multi period forecasts made by chase econometrics inc between 1970 and 1979

capital allocative disturbances and economic fluctuations permanent sector specific productivity shocks alter the relative marginal products of capital and labor across sectors such that the existing factor allocations are suboptimal the subsequent factor reallocations may involve the costly movement and redeployment of capital and labor across sectors to proxy the magnitude of these disturbances this paper focuses on capital rather than labor allocative disturbances since firms can make temporary adjustments in employment levels in response to transitory sectoral shocks empirical evidence is provided that these costs reduce output from what it otherwise would have been and that this effect persists for up to three quarters copyright 1993 by mit press

the relative adjustment of wages and prices direct tests within a multiple equation system in order to assess the relative rigidity of the aggregate price level and the nominal wage rate most researchers have focused on the implied behaviour of the real wage rate in response to a purely demand disturbance the present work examines the explicit behaviour of the two variables and is therefore able to analyse the variables short run responses within the context of their defined long run behaviour while the paper reports evidence of long run stability in the real wage rate additional evidence is presented which supports both sticky price and sticky wage models the determining factor is the choice of lag

joint risk preference technology estimation with a primal system applied studies of the firm in a risky environment have concentrated either on the firm s technology or on its risk preferences these models result in generally inconsistent and inefficient parameter estimates a primal model is proposed which allows a firm s preferences and technology to be estimated jointly in the presence of risk the model is applied to iowa corn production and estimated technology parameters are compared with those from other approaches modest risk aversion leads to inelastic even backbending per acre supplies and input demands yield heteroskedasticity in inputs leads to supply heteroskedasticity in prices especially for risk neutral firms

tests of the relation between money and output in the real business cycle model abstract the paper contains tests of the relation between money and output implied by a real business cycle model the tests control for a variety that may affect economic growth and the growth rates of monetary aggregates using u s data from 1953 1 1984 4 we find almost no evidence that the empirical relations between real growth and measures of monetary policy violate the restrictions imposed by the model changes in a set of real variables explain a majority of the variation in gnp growth however substantial variation in gnp growth remains unexplained by the real factors that we consider

an empirical two market disequilibrium model for dutch manufacturing abstract we develop an empirical version of the aggregate two market fixprice model due to barro and grossman maximum likelihood estimation of the model appears to be difficult as a large number of local maxima occurs the number of local maxima is considerably reduced by the introduction of prior information on some of the standard deviations of the disturbance terms in the model satisfactory estimation results are obtained this way the model closely reproduces the post war dutch trade cycle although some problems remain especially with the seventies

anticipated effects of the minimum wage on prices there is little empirical evidence on the effect of minimum wage increases on prices particularly for developing countries this paper provides estimates of this effect using monthly brazilian household and firm data over 18 years as minimum wage increases in brazil sare large and frequent they have a potentially important impact on aggregate prices rational agents in anticipation of such price effects may take minimum wage increases as a signal for future price and wage bargains we find that the minimum wage raises overall prices not only on the month of the increase but also in the two months prior to the change as well as after the change

risk aversion and price risk in duality models of production a linear mean variance approach a duality model of production is developed that permits risk aversion and price uncertainty the linear mean variance framework employed is tractable for empirical research in contrast to duality models of risk based on a generalized expected utility function the framework is more general than in standard price certainty models while retaining the simplicity needed for empirical research

the new keynesian synthesis the new keynesians made more rapid progress in understanding the microeconomics of unemployment than in understanding the microeconomics of nominal price rigidity but the past five years have seen important breakthroughs in this second area this paper will describe these breakthroughs discuss our current understanding of nominal rigidity and assess the work that remains to be done

testing for labor market equilibrium with an exact excess demand disequilibrium model a bstract the standard disequilibrium model is supplemented with outside information on the extent of market excess demand estimation of this supplemented model is considerably less involved than that of the standard model and certain desirable structural features such as improved dynamics are obtained in addition a simple nested test of the hypothesis of market equilibrium is available the model is estimated with aggregate u s post war labor market data and the econometric test rejects the hypothesis of labor market equilibrium

a political model of monetary policy with application to the real fed funds rate abstract we construct an empirical model of u s monetary policy assuming that the federal reserve is an ordinary federal bureaucracy we use the real federal funds rate as our policy measure and show the existence of significant executive legislative and bureaucratic influence on the real rate of interest from 1961 to 1996 we find that presidential party is an adequate statistical measure of executive influence and that the voting scores of the senate banking committee leadership best represent legislative influence we argue that political changes cause systematic and predictable changes in monetary policy

the costs of global tariff barriers on wool products 1997 2005 the doha round of multilateral trade negotiations commits world trade organization wto members to improving market access for both agricultural and nonagricultural goods tariff barriers on wool products represent a small but important subset of these negotiations to inform the debate on the round we analyze the distortionary effects of recent 1997 2005 tariff barriers on wool products using a model that applies a comprehensive analytical approach with regard to the production trade and consumption of wool products we also account for any indirect effects of wool tariff barriers on the nonwool economy by incorporating the production trade and consumption of nonwool products that is the framework is a comparative static global general equilibrium model with a detailed representation of the world wool market changes in wool tariffs over 1997 2005 lead to positive welfare effects for most regions italy china and the uk are estimated to have gained the most from the changes the results indicate that the nature of recent wool tariffs severely distort the size of wool industries in different regions the changes in the output of wool commodities are extreme reflecting the discriminatory nature of the tariffs

do real business cycle models really exhibit business cycle behavior abstract previous research indicates that real business cycle models are capable of reproducing important features of u s business cycle behavior here i employ classical methods of business cycle analysis to determine how well the cyclical properties of simulated data from a representative real business cycle model match up with postwar u s business cycle characteristics while the simulated model reproduces qualitative features consistent with observed business cycle experience quantitative goodness of fit tests show that for many sectors of the economy the cyclical characteristics of the simulated data deviate significantly from u s business cycle experience

cost functions under production uncertainty we characterize the cost functions which would be consistent with expected utility maximization when production is uncertain it is not generally possible assuming risk aversion to use only expected output as the constraint in a cost minimization problem in some leading cases cost functions consistent with expected utility maximization are particularly useful because they are devoid of risk preferences

interest rate innovations and the business cycle abstract recent evidence from vector autoregressions points towards the importance of interest rate innovations in explaining output variations we show that this evidence supports an interpretation of business cycles based on nominal contractual rigidities rather than cotinuous market clearing

the source of fluctuations in money evidence from trade credit abstract this paper tests the relative importance of technology shocks and financial shocks as sources of fluctuations in money the model extends the theory of king and plosser 1984 by recognizing that both money and trade credit provide transactions services under certain conditions the co movements between money and trade credit can reveal the nature of the underlying shocks the empirical results strongly suggest that shocks to the financial system account for most of the fluctuations in money in the long run and at business cycle frequencies on the other hand technology shocks appear to be more important at seasonal frequencies

tests of equilibrium macroeconomics using contemporaneous monetary data abstract this paper uses contemporaneous monetary data to carry out econometric tests of the equilibrium approach to modelling the relation between monetary disturbances and macroeconomic fluctuations the theoretical analysis introduces into an equilibrium macroeconomic model the availability of preliminary data on current monetary aggregates and the process of accumulation of revised monetary data the econometric analysis tests two hypothesis derived from this extended model one hypothesis concerns the neutrality of perceived monetary policy the econometric results imply rejection of this hypothesis the other hypothesis concerns the non neutrality of errors in preliminary monetary data the econometric results fail to reject the contrary of this hypothesis these tests provide strong evidence against the reality of the equilibrium approach

do government policy multipliers decrease with inflation abstract we use cross country data to examine the effects of inflation on government spending and monetary policy multipliers in contrast to earlier work by ball mankiw and romer 1988 and defina 1991 we allow for differential impacts of both the monetary base and government spending and this difference turns out to be empirically quite important we find little evidence in favor of a new keynesian sticky price model

trends random walks and the expectations augmented phillips curve evidence from six countries two major empirical results are reported first it is shown that time series measuring real activity in major industrialized countries contain nonstationarities of the random walk type second it turns out that the estimated influence of unexpected changes in inflation and monetary growth strongly depends on the chosen approach concerning nonstationarity the popular assumption of a deterministic time trend proxying for growth generally yields the hypothesized positive coefficients the influence of nominal surprises however becomes indistinguishable from zero if the respective equations are estimated in stationary differences of real activity variables copyright 1988 by ohio state university press
