targeting inflation by constant interest rate forecasts this paper reviews the concept of constant interest rate inflation forecast cir targeting it stresses the time inconsistent nature of cir targeting and provides a new method for constructing cir forecasts consistently in the context of models with forward looking variables a dynamic new keynesian model with forward looking price setting is used as an illustration suggesting that the main reason for choosing a relatively long forecast targeting horizon lies in the monetary authorities objective to smooth interest rate movements as greater nominal and real stabilization is achieved at a relatively short inflation forecast targeting horizon

finance inflation and employment a post keynesian kaleckian analysis the purpose of this paper is to contribute to the post keynesian kaleckian macroeconomic literature we develop a macroeconomic model that explicitly integrates the role of borrowing and cash payment commitments on outstanding debt interest plus principal repayment into the consumption and investment expenditures as well as into the inflation generating process we explore the way that finance influences the distribution effects of inflation in the demand side of a money credit using economy we suggest a new phillips curve that encapsulates the impact of financial commitments on wage and profit claims we argue that high debt and cash payment commitments are likely to be associated with a positive demand side effect of inflation on the rate of employment and that they might be conducive to a negative supply side effect of employment on the inflation rate the author 2011 published by oxford university press on behalf of the cambridge political economy society all rights reserved

the phillips curve the persistence of inflation and the lucas critique evidence from exchange rate regimes comment we present evidence from the united states and the united kingdom that the persistence of price inflation is significantly higher under managed exchange rate regimes than under gold based fixed exchange rate regimes these differences are also reflected in expectations augmented phillips curves we use a two country macro model with forward looking price setters to demonstrate that higher monetary accommodation of inflation and exchange rate accommodation of inflation differentials increase inflation persistence the evidence does not contradict this hypothesis it supports the hypothesis of forward looking price setters and highlights the empirical significance of the lucas critique jel e31 e42 f33

optimal monetary policy responses to relative price changes abstract an optimizing model with a flexible price sector and a sticky price sector is presented to analyze the effects of relative price changes on inflation fluctuations the relative price of the flexible price good represents a shift parameter of the new keynesian phillips curve the optimal monetary policy is to target sticky price inflation rather than a broad inflation measure although stabilizing the relative price around its efficient value is one of the appropriate goals of the central bank stabilizing sticky price inflation is sufficient for achieving this goal an optimal monetary policy for a small open economy is also discussed

empirical evidence on inflation expectations in the new keynesian phillips curve abstract we review the main identification strategies and empirical evidence on the role of expectations in the new keynesian phillips curve paying particular attention to the issue of weak identi

firm size and the nature of innovation within industries the case of process and product r d the effect of firm size on the allocation of r d effort between process and product innovation is examined it is hypothesized that relative to product innovations process innovations are less saleable in disembodied form and spawn less growth this implies that the returns to process r d will depend more on the firm s output at the time it conducts its r d than the returns to product r d incorporating this distinction in a simple model the authors derive and test predictions about how the fraction of r d devoted to process innovation varies with firm size within industries

war labor tournaments and contest payoffs abstract when prizes change with effort contestants adjust effort to mitigate that change net payoffs remain unchanged respectively can be larger if prizes are linear concave in effort contest designers can facilitate desired outcomes by making the prize concave in effort

reconciling the wage curve and the phillips curve the wage curve is the negative relationship that links wage levels to the unemployment rate it fits accurately with modern non competitive labour market models but goes against a phillips curve modelling because the latter ties wage growth to the unemployment rate in this article we present a comprehensive review of these non competitive models highlighting recent contributions that try to eliminate the possible gap that exists between the concepts of the wage curve on the one hand and the phillips curve on the other copyright blackwell publishers ltd 2005

stabilising properties of discretionary monetary policies in a small open economy this article sets out a simple new keynesian open economy model and shows that the conduct of discretionary monetary policy in an open economy differs substantially from the closedeconomy framework the article shows analytically that the existence of the direct exchange rate channel in the open economy phillips curve impairs the perfect stabilising property of monetary policy in the face of demand side disturbances under domestic inflation targeting if cpi inflation is instead the target then the perfect stabilising property of monetary policy breaks down even in the absence of the direct exchange rate channel in the phillips curve

the new keynesian phillips curve revisited abstract several authors have questioned the evidence claimed by gali and gertler 1999 and gali et al 2001 that a hybrid version of the new keynesian phillips curve approximates european and us inflation dynamics quite well we re examine the evidence using the vector autoregressive framework and likelihood based methods paying particular attention to the stationary and nonstationary and possibly cointegrated nature of variables involved our results show that the exact as well as the inexact form of the hybrid nkpc are clearly at odds with the european data on the other hand gali and gertler 1999 finding that the inexact hybrid nkpc is a good first approximation to the us inflation dynamics seems less at odds with the data however the assumption of the model that the stochastic term forms a sequence of innovations may be problematic as we find indication of autocorrelation in the estimated residuals the exact form of the hybrid nkpc is firmly rejected by the us data

menu costs and the neutrality of money a model of endogenous price adjustment under money growth is presented firms follow s s pricing policies and price revisions are imperfectly synchronized in the aggregate price stickiness disappears and money is neutral the connection between firm price adjustment and relative price variability in the presence of monetary growth is also investigated the results contrast with those obtained in models with exogenous fixed timing of price adjustment

testing the rationality of inflation expectations derived from survey data a structure based approach following the inspiration of muth 21 expectations are said to be rational if the subjective probability distribution of expected outcomes coincides with the objective probability distribution of actual outcomes in practical applications however it is common to employ the so called weak form version of this hypothesis which defines rationality as equality between the expected outcome and the objective mathematical expectation conditional on all data available at the time the expectation is formed thus expectations of inflation are said to be weakly rational in muth s sense if

incumbent positioning as a determinant of strategic response to entry existing research has identified different firm characteristics that determine an incumbent s reaction toward market entrants this study widens the perspective from a firm s absolute attributes to its relative positioning within its competitive environment the hypotheses for the empirical analysis are derived from game theoretic models with either vertical or horizontal product differentiation in each of the two theoretical models two incumbents initially choose very different quality and variety levels respectively and move closer to the center when faced by entry of a competitor from the vertical differentiation model we predict a stronger price reduction by high quality firms in our empirical analysis we are using a novel dataset of the high quality restaurant market in germany to test the theoretical findings while the hypotheses with respect to adjustments of prices and varieties are supported we do not find empirical evidence for the predicted quality adjustment

money and inflation in the euro area a case for monetary indicators abstract this paper examines inflation indicators for the euro area by studying the relationship between inflation output money and interest rates using data spanning 1980 2001 the central finding is that both the output gap and the real money gap the difference between the real money stock and the long run equilibrium real money stock contain considerable information regarding future inflation in contrast the eurosystem s money growth indicator the difference between nominal money growth and a reference value the prominent first pillar in its monetary strategy contains little information about future inflation and no information beyond that contained in the output and real money gaps the predictive performance of the output gap has improved compared to that in a previous version of this paper most likely because of better estimation methods

incumbent innovation and domestic entry this paper analyzes the escape entry incentive for innovation by incumbent firms the threat posed by the possibility of leading edge firms entering the market influences incumbent innovation to overcome problems of endogeneity we apply an instrumental variable approach to analyze a rich firm level dataset 1987 2000 for germany we find evidence that domestic entry has a negative effect on incumbent product innovation which is a strong indication of new entrants comparative advantage in commercializing new ideas in contrast domestic entry has a positive effect on incumbent process innovations an effect also known as the escape entry effect

sticky prices new evidence from retail catalogs this paper presents new results on the size frequency and synchronization of price changes for twelve selected retail goods over the past 35 years three basic facts about the data are uncovered first nominal prices are typically fixed for more than one year although the time between changes is very irregular second prices change more often during periods of high overall inflation third when prices do change the sizes of the changes are widely dispersed both large and small changes occur for the same item and the sizes of these changes do not closely depend on overall inflation

efficiency and formation of expectations evidence from the european investment survey the european commission conducts an annual survey regarding planned and realized business fixed investment across various manufacturing sectors in euroland in this study we investigate the predictive content of survey based expectations on investment in addition we empirically test the rationality of respondents both in a time series as well as in a panel context according to our results based on pooling the data efficiency is rejected since expectations are biased predictors of actual outcomes furthermore expectations revisions are found to be correlated with components of the information set known at the time of decision making finally our results qualify regressive expectations as the mechanism that more adequately describes the formation of expectations

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

estimation of limited dependent variable models with dummy endogenous regressors applied economists have long struggled with the question of how to accommodate binary endogenous regressors in models with binary and nonnegative outcomes i argue here that much of the difculty with limited dependent variables comes from a focus on structural parameters such as index coefcients instead of causal effects once the object of estimation is taken to be the causal effect of treatment several simple strategies are available these include conventional two stage least squares multiplicative models for conditional means linear approximation of nonlinear causal models models for distribution effects and quantile regression with an endogenous binary regressor the estimation strategies discussed in the article are illustrated by using multiple births to estimate the effect of childbearing on employment status and hours of work

the rigidity of prices this paper uses evidence on individual transaction prices to analyze price behavior the evidence shows that for many transactions pricesremain rigid for periods exceeding one year the rigidity of price ispositively correlated with industry concentration for several productsthe correlation of price changes across buyers is low the paper alsoinvestigates the relationship between price rigidity price change andthe length of time a buyer and seller have been doing business together the author interprets the evidence as emphasizing the importance of nonprice rationing and the inadequacy of models in whichprice movements alone clear markets copyright 1986 by american economic association

has euro area inflation persistence changed over time this paper analyzes the stability over time of the econometric process for euro area inflation since 1970 focusing in particular on the behavior of the so called persistence parameter the sum of the coefficients on the lagged dependent variables perhaps surprisingly in light of the lucas critique our principal finding is that there appears to be relatively little instability in the parameters of the euro area inflation process full sample estimates of the persistence parameter are generally close to 1 and we fail to reject the hypothesis that this parameter has been stable over time we discuss how these results provide some indirect evidence against rational expectations models with strong forward looking elements such as the new keynesian phillips curve

routinization of innovation in german manufacturing the david goliath symbiosis revisited small and medium sized firms frequently are viewed as the drivers of radical innovation however they often do not have the focus and commitment necessary for improving and extending the innovation tasks better accomplished by routinized large firms using a uniquely rich industry level data set for german manufacturing industries during 1991 2004 this article finds evidence for this david goliath symbiosis although small and medium sized firm innovation rates can explain the within industry variation of productivity growth it is the large firm process innovation rate that explains differences in the level of productivity growth between industries i e differences in the degree of routinization of innovation

dynamic inconsistencies counterfactual implications of a class of rational expectations models a number of recent papers have developed dynamic macroeconomic models that incorporate rational expectations and optimizing foundations while the theoretical motivation behind these models is sound the dynamic implications of many of the specifications that assume rational expectations and optimizing behavior can be seriously at odds with the data for both inflation and real side variables exhibit gradual and hump shaped responses to real and monetary shocks for models that are intended for monetary policy analysis these dynamic shortcomings should be considered quite serious when monetary policy has only short run effects on real variables the inability to approximately capture the short run responses of inflation or real variables to policy shocks makes a model unsuitable for policy analysis this paper identifies a simple feature common to many dynamic specifications for prices and real variables that causes the problem the paper also discusses several potential solutions to the problem including alterations to the expectations assumption to the order of differencing implicit in the model and to the underlying behavioral assumptions this abstract was borrowed from another version of this item
