implications of economic interdependence for endogenous wage indexation decisions this paper shows how economic interdependence affects the indexation decisions of atomistic wage setters in an environment in which monetary authorities do not observe stochastic disturbances before making their policy choices if stochastic disturbances are common across countries interdependence has no effect on equilibrium indexation choices in identical countries however if disturbances are country specific numerical simulations show that interdependence is likely to reduce equilibrium indexation choices relative to a small open economy we also show that indexation choices may be either strategic complements or strategic substitutes but that strategic complementarity becomes more likely as the degree of interdependence rises

wages relative prices and the choice between fixed and flexible exchange rates this paper reexamines the choice between fixed and flexible exchange rates to take into account wage indexation and flexible prices the difference in output variation in the two exchange rate regimes is shown to be dependent on wage behaviour in the domestic economy being proportional to one minus the degree of wage indexation foreign wage behaviour is also shown to be of key importance since high wage indexation abroad can insulate the domestic country from some foreign disturbances regardless of domestic behaviour while for other economic disturbances it is the relative degree of wage indexation which determines the desirability of flexible rates niveaux de salaires prix relatifs et le choix entre les regimes de taux de change fixes ouflucttuants ce memoire reouvre le dossier du choix entre regime de taux de change fixes et regime de taux de change fluctuants quand on tient compte de l indexation des salaires et de la flexibilite des prix il appert que l ecart entre les variations du niveau de production domestique entre les deux regimes depend du comportement des salaires dans l economie domestique il est proportionnel a 1 le degre d indexation des salaires le comportement des salaires dans le reste du monde est aussi important puisque un haut degre d indexation des salaires dans le reste du monde peut proteger l economie domestique de certaines perturbations economiques h l etranger quel que soit le comportement des salaires domestiques dans le cas d autres perturbations economiques c est le degre relatif d indexation des salaires h l interieur et h l exterieur qui devient le facteur determinant dans le choix d un regime de taux de change how much difference a flexible exchange rate makes to the economic performance of a country depends significantly on wage behaviour if wages are sufficiently sensitive to exchange rates output will exhibit much the same variability under flexible exchange rates as under fixed rates foreign wage behaviour is also of key importance since high wage flexibility abroad can insulate the domestic country from some foreign disturbances regardless of domestic wage behaviour while for other economic disturbances it is the relative degree of wage flexibility which determines the desirability of flexible rates this paper re examines the choice between fixed and flexible rates taking into account both domestic and foreign wage

supply shocks wage indexation and monetary accommodation this paper develops a unified framework for the analysis of wage indexation and monetary policy in the presence of supply shocks we first present simple formulae for the optimal wage indexation rule and for the optimal money supply rule in order to set the stage for an evaluation of departures from the optimal policy rules we first analyse two extreme cases a rule that stabilizes employment and a rule that stabilizes the real wage the analysis of these two extreme cases provides the ingredients for the evaluation of various rules for wage indexation and for monetary targeting we examine the implications of indexing wages to i nominal gnp ii the cpi and iii the value added price index as well as the implications of targeting the money supply to these alternative three indicators it is shown that the various indexation rules bear a dual relation to the various monetary targeting rules the welfare ranking of the various rules depends on whether the elasticity of the demand for labor exceeds or falls short of the elasticity of labor supply if the demand for labor is more elastic than the supply then policy rules that stabilize employment produce a smaller welfare cost than policy rules that stabilize the real wage in that case indexing wages to nominal gnp results in a smaller welfare cost than indexing to value added price index which in turn produces a smaller cost than indexation to the cpi because of the dual relation between monetary policy and wage indexation it follows that under the same circumstances monetary policy that targets nominal gnp produces a smaller welfare cost than policy that targets the value added price index which in turn results in a smaller cost than the policy that targets the cpi this ranking is reversed when the elasticity of the supply of labor exceeds the elasticity of demand this abstract was borrowed from another version of this item

partial ownership arrangements and collusion in the automobile industry this paper develops a conjectural variation model that allows for partial ownership arrangements and foreign trade this model is applied to the japanese and us automobile industries although collusion is found to occur in the japanese automobile industry it is found to be more competitive than the us automobile industry the effect imports have on firms price cost margins in both countries is also found to be different

supply shocks wage stickiness and accommodation the key issue in the supply shock literature that developed after the 1973 74 oil and food price shocks was whether to accommodate l there is of course nothing to be done about the reduction in the equilibrium level of output caused by the supply shock but twice in the 1970s supply shocks resulted in output falling below its potential level the question discussed in the supply shock literature and taken up here is whether government policy is either responsible for or can offset the fall in the level of output to below its potential level i also discuss the costs and benefits of alternative policy responses to a supply shock it will be seen that the basic issues are precisely those that arise in considering activist policy in general the paper opens by discussing optimal responses to a supply shock in a one sector model these would be observed if markets cleared at all times in section 2 i examine the behavior of output and prices when wages are slow to adjust to the supply shock the key factors here are whether the supply shock requires a reduction in the real wage and whether there is real wage resistance by workers in contrast to much of the recent literature i concentrate on the closed economy 2 the supply shock is domestic and there is no recourse to foreigners to mitigate its effects the main result of the paper is that supply shocks by themselves are unlikely to lead to unemployment if monetary policy remains passive and so long as there is no

panel data estimates of the production function and product and labor market imperfections summary consistent with two models of imperfect competition in the labor market the efficient bargaining model and the monopsony model we provide two extensions of a microeconomic version of hall s framework for estimating price cost margins we show that both product and labor market imperfections generate a wedge between factor elasticities in the production function and their corresponding shares in revenue which can be characterized by a joint market imperfections parameter using an unbalanced panel of 10 646 french firms in 38 manufacturing industries over the period 1978 2001 we can classify these industries into six different regimes depending on the type of competition in the product and the labor market by far the most predominant regime is one of imperfect competition in the product market and efficient bargaining in the labor market ic eb followed by a regime of imperfect competition in the product market and perfect competition or right to manage bargaining in the labor market ic pr and by a regime of perfect competition in the product market and monopsony in the labor market pc mo for each of these three predominant regimes we assess within regime firm differences in the estimated average price cost mark up and rent sharing or labor supply elasticity parameters following the swamy methodology to determine the degree of true firm dispersion to assess the plausibility of our findings in the case of the dominant regime ic eb we also relate our industry and firm level estimates of price cost mark up and extent of rent sharing to industry characteristics and firm specific variables respectively copyright 2011 john wiley sons ltd

manufacturing margins differences between small and large firms the influence of labour costs concentration capacity utilization exports and firm size on manufacturing profit margin is studied with a discrimination between small and large firms

price flexibility in japan 1970 1992 a study of price formation abstract we estimate probability and size of price change conditional upon the deviation of a price from its target level for a large number of individual wholesale and consumer price indices in japan we find robust and strong asymmetry in price adjustments especially among cpis cross section variations in price responsiveness depend upon characteristics of distribution channels in particular efficiency and input measures of distributive services using a simulation model we also find that the macroscopic downward rigidity almost disappears if the size of the shock is small compared to the target inflation rate

monetary accommodation of supply shocks under rational expectations in dealing with the expectationists arguments i will divide them somewhat artificially into two groups arguments in the first group which i call present disaster arguments allege that econometric models err by understating the reaction of inflationary expectations for example it is claimed that a policy of monetary accommodation would increase inflationary expectations shift the short run phillips curve upward and defeat the purpose of the expansionary policy arguments in the second group which i call future disaster arguments are more subtle but also more elusive the idea is that by informing private agents that it will accommodate supply shocks in the future the monetary authority would exacerbate the downward rigidity of wages and prices thus making it more difficult to deal with future supply shocks such arguments are cases of the lucas 12 econometric policy critique since they suggest that policy changes will cause parameter shifts neither of these arguments is implausible on its face the problem is that it is hard to know how to evaluate them until they are formalized in theoretical models and then tested empirically this paper takes one small step in that direction by augmenting two popular macro models with rational expectations so that they are capable of dealing with supply shocks and then examining both the present and future disaster arguments in the context of each this abstract was borrowed from another version of this item

business cycles and the relationship between concentration and price cost margins using a newly constructed panel data base we examine changes in price cost margins in 284 manufacturing industries between 1958 and 1981 a key finding is a dramatic narrowing of the spread between the margins of concentrated and unconcentrated industries over this period we provide evidence that this narrowing is a result of the greater sensitivity of price cost margins in more concentrated industries to demand fluctuations this finding is robust to the inclusion of other industry variables and to measures of import competition the results indicate that cross sectional estimates of the concentration margins relationship are likely to be both biased and misleading

optimal wage indexation and monetary policy in an economy with imported raw materials abstract an economy s openness from the input side has important effects on the optimal design of its macroeconomic policies given the exchange rate regime the larger the share of imported raw materials in domestic production the smaller the optimal degree of wage indexation to unanticipated inflation alternatively given the wage indexation parameter the larger the share of imported raw materials in domestic production the smaller the optimal degree of foreign exchange intervention by the monetary authority the more flexible the exchange rate

price mark ups market structure and business fluctuation in japanese manufacturing industries howard wach tel and peter adelsheim 1977 and keith cowling 1983 have argued that firms in concentrated industries tend to increase their price mark ups in recession this hypothesis is variously tested for japanese manufacturing industries in 1958 82 most of the results weakly suggest an effect opposite to wachtel and adelsheim and only when industry specific business conditions are taken into account is some albeit weak evidence found in favor of them copyright 1987 by blackwell publishing ltd

openness relative prices and macro policies abstract this paper analyzes the role of relative prices in the conduct of wage indexation monetary policy and exchange rate policy in a small economy producing traded and nontraded goods under a managed float exchange rate regime it is shown that the beneficial effect of using relative prices in addition to aggregate prices as indicators for the conduct of the above policies increases with openness the response of policies to relative prices rises with openness and has dampening effects on the volatility of deviations from purchasing power parity

estimating the mark up over marginal cost a panel analysis of japanese firms 1971 1994 abstract in this paper we propose a new method to estimate mark ups over marginal cost at the firm level this method is based on the identity between the short run elasticity of output to inputs the mark up rate and the factor shares we then apply this method to a panel of japanese firms in 21 industries over 24 years we have three main results first there is strong evidence of imperfect competition in this panel in which internationally competitive industries show low mark ups second the mark up rate differs considerably among firms and its distribution is skewed third the mark up rate over marginal cost shows strong procyclicality and its sensitivity is uniform within the industry

on optimal wage indexation the observed practice of contracting for labor services in advance introduces stickiness or friction into the economic system in the presence of monetary and real stochastic disturbances the stability of the levels of employment and output hinges on the nature of the wage contracts in this paper we demonstrate the existence of optimal indexation schemes that are capable of eliminating the aforementioned friction by duplicating the equilibrium that would obtain if labor services were contracted for after the stochastic disturbances were realized

the transmission of disturbances under alternative exchange rate regimes with optimal indexing the paper develops a general stochastic macroeconomic model that can be used to study the international transmission of disturbances under four alternative exchange rate systems uniform flexible exchange rates uniform fixed exchange rates and two versions of two tier exchange rates the analysis makes two general points first one cannot assume stability of structure when assessing the consequences of alternative exchange rate regimes for example the slope of the aggregate supply curve and the rationally formed expectations in the asset markets can respond dramatically to the government s choice of exchange rate regime second exchange rate regimes that provide full insulation from foreign disturbances may nevertheless be inferior to other regimes in terms of their ability to maximize social welfare

determinants of price adjustment this paper reports results of an empirical study investigating the adjustment speed of prices to change in costs and demand particular emphasis is laid on the impact of concentration on the adjustment speed in addition the effects of the business cycle and capital intensity are considered it shows that concentrated industries tend to adjust prices faster while capital intensity has a negative impact prices are more flexible during an upswing than in times of a recession

wage flexibility and openness this paper analyzes the degree of short run real wage flexibility in a two sector economy under floating rates this is done by deriving optimal wage indexation in a contracting framework we find that the more closed the economy the lower the degree of wage indexation as a result output will fluctuate less around its desired level in a more closed economy these findings further imply that a given unexpected monetary shock will cause as maller output shock in a more open economy whereas a given real shock will induce a smaller output shock in a more closed economy this abstract was borrowed from another version of this item

raw materials profits and the productivity slowdown a factor price frontier framework is used to clarify the analogy of an increase decrease in raw material prices with autonomous technological regress progress factor price profiles are estimated for the manufacturing sector of the united states the united kingdom germany and japan the production model in conjunction with estimates obtained from the factor price frontier attributes much of the slowdown in manufacturing productivity to the rise in relative raw material prices part of the apparent productivity riddle may have to do with the use of double deflated national accounting measures of value added which have an inherent measurement bias

imported materials prices wage policy and macroeconomic stabilization this paper analyses two simple wage rules that keep employment constant when there are shocks to the prices of imported materials one rule ties nominal wages to the gnp deflator rather than the consumer price index the second rule followed by japan after the second oil price shock ties the real wage to real gnp the paper shows the effects on output real income and other macro economic variables of choosing either rule in place of the real wage stability provided by conventional wage indexation

modelling systemic risk and dependence structure between the prices of crude oil and exchange rates in brics economies evidence using quantile coherency and ngcovar approaches abstract in this study we examine the dependence structure and systemic risk between return series of the prices of crude oil and the brics exchange rates to us using the quantile coherency methods of barunik and kley 2015 and the nonparametric conditional value at risk granger causality test hereafter ngcovar of diks and wolski 2018 over the period 2005 2017 further we use the hiemstra and jones 1994 hereafter hj and diks and panchenko 2005 hereafter dp tests for comparison purposes our findings indicate that all countries reveal significant negative dependence in the long run dynamics between oil prices and brazilian indian and south african currencies hj and dp tests suggest that lagged crude oil prices have predictive power for the brazilian and russian exchange rates furthermore a robust unidirectional lagged dependence exists from the brazilian exchange rate to crude oil prices concerning the chinese indian and south african currencies we find no contagion effects from to those countries to the oil market for russia there is limited evidence of contagion effects these findings provide insights for regulators and international investors

macroeconomic stabilization through taxation and indexation the use of firm specific information abstract this paper considers two alternative approaches to stabilizing an economy with firm specific productivity disturbances the first uses wage contracts tying wages in each firm to these disturbances as well as the price level the second uses a taxation scheme together with a wage indexation rule tying wages to prices alone both these schemes are viable as long as the firm specific disturbance is known to all agents if the firm alone observes the productivity disturbance under either scheme it has an incentive to misrepresent current conditions however a combination of these two schemes is both welfare maximizing and incentive compatible

wage indexation and exchange market intervention in a small open economy the analysis of this paper stresses the interdependence between wage indexation on the one hand and exchange market intervention on the other as tools of macroeconomic stabilization policy in a small open economy subject to stochastic disturbances it is shown how the choice of eitherpolicy instrument impinges on the effectiveness of the other in particular if the domestic money wage is fully indexed to some weighted average of the domestic and foreign price levels then irrespective of what that chosen weight may be exchange market intervention is rendered totally ineffective insofar as the stabilization of the real part of the domestic economy is concerned likewise if the monetary authority intervenes in the exchange market so as to exactly accommodate for nominal movements in the demand for money thereby rendering the excess demand for money dependent only upon real variables then any form of wage indexation is totally ineffective for the stabilization of the real part of the system in either polar case the respective instrument can stabilize the domestic price level alternative combinations of policy for the stabilization for domestic and foreign disturbances are considered this abstract was borrowed from another version of this item

optimal wage indexation foreign exchange intervention and monetary policy this paper deals with the design of optimal monetary policy and with the interaction between the optimal degrees of wage indexation and foreign exchange intervention the model is governed by the characteristics of the stochastic shocks which affect the economy and by the information set that individuals possess because of cost of negotiations nominal wages are assumed to be precontracted and wage adjustments follow a simple indexation rule that links wage changes to observed changes in price the use of the price level as the only indicator for wage adjustments may not permit an efficient use of available information and may result in welfare loss the analysis specifies the optimal set of feedback rules that should govern policy aiming at the minimization of the welfare loss these feedback rules determine the optimal response of monetary policy to changes in exchange rates interest rates and foreign prices the adoption of the optimal set of feedback rules results in the complete elimination of the welfare cost arising from the simple indexation rule and from the existence of nominal contracts since optimal policies succeed in the elimination of the distortions issues concerning the nature of contracts and the implications of specific assumptions about disequilibrium positions become inconsequential the analysis then proceeds to examine the interdependence between the optimal feedback rules and the optimal degree of wage indexation it is shown that a rise in the degree of exchange rate flexibility raises the optimal degree of wage indexation one of the key conclusions is the proposition that the number of independent feedback rules that govern a policy must equal the number of independent sources of information that influence the determination of the undistorted equilibrium thus it is shown that with a sufficient number of feedback rules for monetary policy there may be no need to introduce wage indexation it is also shown that an economy that is not this abstract was borrowed from another version of this item
