profit sharing and productivity some further evidence new estimates for west germany indicate overall productivity differentials of 20 30 percent in favor of firms practicing profit sharing these compare with estimates of 3 8 percent for comparable british firms reported in a recent issue like the u k results they reveal important interactions between profit sharing and other firm specific characteristics reinforcing the view that profit sharing be regarded as an integral element of overall organizational design but the fact that in germany profit sharing is apparently used in a different way than in the united kingdom by different kinds of firms suggests that there is no single uniquely appropriate context and role for profit sharing copyright 1990 by royal economic society

central bank preferences and macroeconomic equilibrium abstract we investigate the behavior of an optimizing monetary authority in an economy described by a simple as ad model we develop a simple methodology for deriving the optimal policy and the associated model solution for various forms of the authority s objectives in our empirical work we focus on one of these specifications in which the authority cares about both the rate of inflation and the level of price innovations which boost real output in our model along the lines of barro and gordon 1983b estimating the model on post war us data we find that the revealed weight on price surprises is significant but only around a third of that on inflation the estimated elasticity of output with respect to price surprises is around one quarter but statistically insignificant

generalised morality and the problem of transition to an impersonal exchange regime a response to platteau this essay addresses the problem of transition from a personalised exchange regime that characterises most ldcs to the more impersonal form of exchange that marks advanced market economies this debate has received impetus from the discussion launched by platteau 1994 in the pages of this journal where he seeks to clarify the social conditions that allow the market system to evolve while the role of private and public order institutions in generating market order is recognised this is regarded as inadequate necessitating the invocation of generalised morality gm to complete the explanation it is argued here that gm does not need to be invoked the article pleads for taking a closer look at the historical role of risk bearing institutions especially financial institutions evidence from the bangladesh rice market is adduced in support of the contention that there exist elements even within a traditional exchange regime that can evolve into modern impersonal forms this is brought out by ex

performance related pay and firm productivity evidence from a reform in the structure of collective bargaining the authors investigate the causal effect on firm productivity of a switch from fixed wages to collective performance related pay exploiting a reform in the structure of collective bargaining triggered by a social pact they find that an increase in the adoption of collective performance related pay leads to a 3 to 5 productivity gain but that such effect declines over time they show that the effect on productivity varies substantially by firm size industry affiliation and union density both the size of the bonus and the design of the scheme in terms of number and types of parameters used are also important features for a firm s productivity

measuring the time inconsistency of us monetary policy this paper offers an alternative explanation for the great inflation of the 1970s by measuring a novel source of monetary policy time inconsistency in the presence of asymmetric preferences the monetary authorities generate a systematic inflation bias through the private sector expectations of a larger policy response in recessions than in booms the estimated fed s implicit target for inflation has declined from the pre to the post volcker regime the average inflation bias was about 1 before 1979 but this has disappeared over the last two decades because the preferences on output stabilization were large and asymmetric only in the former period

the inflation bias when the central bank targets the natural rate of unemployment abstract this paper studies the proposition that an inflation bias can arise in a setup where a central banker with asymmetric preferences targets the natural unemployment rate preferences are asymmetric in the sense that positive unemployment deviations from the natural rate are weighted more or less severely than negative deviations in the central banker s loss function the bias is proportional to the conditional variance of unemployment the time series predictions of the model are evaluated using data from g7 countries econometric estimates support the prediction that the conditional variance of unemployment and the rate of inflation are positively related

truth trust and market transactions what do we know john humphrey and hubert schmitz have recently made an important contribution to the literature on trust and economic transactions between firms unfortunately the evidence that high levels of societal trust contribute significantly to economic growth is far less reliable than they suggest we need more research but research informed by greater conceptual clarity about trust and the institutional arrangements that contribute to trust the framework presented here for conceptualising the various sources of trust should help guide empirical research

why is inflation low when productivity growth is high i introduction in the united states since world war ii inflation has been low when productivity growth has been high for example the 1950s and 1960s were a period of low inflation and high productivity growth whereas the 1970s and 1980s were a period of high inflation and low productivity growth the negative correlation between inflation and productivity growth over the years 1949 2000 is much stronger than the correlation between inflation and unemployment i e phillips curve type correlations or the correlation between inflation and growth in monetary aggregates i e quantity theory correlations little research has explored the comovement between inflation and productivity growth the evidence developed herein suggests that the negative correlation reflects the behavior of the federal reserve over the postwar period the federal reserve has not adjusted nominal income growth through changes in the growth of the money supply to changes in trend productivity growth as will be documented such a policy induces a negative correlation between trend productivity growth and inflation as an acceleration in trend productivity growth in the face of constant nominal income growth leads to a deceleration in inflation this focus on monetary policy as the key factor behind medium to long run correlations between inflation and productivity seems more plausible than a focus on peculiarities of phillips curve reduced form relationships because such relationships are plausibly more appropriate guides to the short run dynamics of inflation as a case in point consider the recent shift to inflation targeting monetary policy strategies in the united kingdom and sweden which emphasize the key role that monetary policy plays in the inflation outlook over several years the role of monetary policy in generating the strong correlation between productivity growth and inflation in the medium run is developed in a textbook model based on an expectations augmented phillips curve the model s main empirical predictions are confirmed 1 inflation especially expected inflation should fall when trend productivity growth rises and 2 nominal income and nominal wage growth should not change when trend productivity growth changes the model also implies that productivity growth enters a reduced form phillips curve relationship as a proxy for inflation expectations this implies that traditional estimates of the nonaccelerating inflation rates of unemployment nairu should fall when productivity growth accelerates an empirical regularity that has received a great deal of academic and policy attention in recent years and is typically explained via some type of irrationality perhaps surprisingly these empirically regularities do not rely on the great inflation of 1965 79 when inflation accelerated and productivity growth decelerated recent discussions of phillips curve reduced form relationships have placed a strong emphasis on structural explanations that may explain a link between productivity growth the nairu and hence inflation staiger et al 2001 present evidence that the time series techniques they employ to estimate trend productivity growth and the nairu yield a strong correlation between the nairu and trend productivity growth ball and moffitt 2001 and ball and mankiw 2002 provide a structural interpretation labor market institutions for some reason perhaps irrationality make the real wage aspirations of workers respond very sluggishly with a lag of perhaps 10 years or more to productivity growth and hence an acceleration in productivity growth leads to a prolonged period of downward pressure on labor costs and hence inflation similar reasoning has been used in policy circles for years at the council of economic advisors 1997 2000 and the federal reserve board meyer 2000 reflecting the reasoning in grub b et al 1982 and braun 1984 the focus herein the behavior of policy is consistent with the evidence on inflation productivity growth and empirical estimates of the nairu

profitability and profit sharing claims that profit sharing is a purely distributive wealth confiscation scheme without incentive effects due to free rider problems are based on neglect of cooperation and interaction in the workforce when these activities are difficult to monitor directly group incentives such as profit sharing can increase efficiency and maintain a superior nashequilibrium with strictly individual optimization with simultaneous wls tobit estimates we find here strong effects of profit sharing and worker ownership shares on residual owners return on capital in medium sized metal working firms in west germany complementing earlier results on productivity

openness and inflation a general equilibrium model of a small open economy is developed to analyse the optimal rate of inflation under discretion once agents welfare is the sole policy objective it is possible to show that openness and inflation no longer have a simple inverse relationship a greater degree of openness may lead the policy maker to want to exploit the short run phillips curve more aggressively even if involves a smaller short run benefit because changes in export demand affect the terms of trade inflation can then be higher in a more open economy

profit sharing and productivity an analysis of uk engineering firms this paper reports productivity differentials of 3 8 percent in favor of profit sharing firms in the u k engineering industry the estimates come from equations in which profit sharing interacts with factor input levels and the firms technological organizational and labor force characteristics and imply more than a simple incentive effect on work effort or more cooperative behavior in given circumstances a technological labor relations interpretation of the origin of the gains is suggested which are found to be asymmetrically distributed the results question policy measures to encourage profit sharing that do not take account of its significance in the process of organizational design copyright 1989 by royal economic society

testing commitment models of monetary policy evidence from oecd economies in ation rates in a number of oecd follow a common trend over the past four decades in ation starts out low in the 1960s rises for a time before peaking in the 1970s or early 1980s and then falls back to initial levels this similarity in the behavior of trend in ation suggests that any explanation of long run in ation trends ought to apply across oecd countries ireland 1999 shows that a simple time inconsistency model of monetary policy modifled to allow for a time varying nairu can explain long run trends in u s in ation in this paper we show that this result cannot serve as an explanation of the common trend in oecd in ation as it flts the data only in the u s we investigate two important variants of the hypothesis i that time inconsistency was an important component of central bank behavior in earlier decades but has become less signiflcant in recent years and ii that time inconsistency problems drive u s in ation which afiects in ation rates in other countries as a result of central bankers attempts to manage nominal exchange rate movements vis a vis the u s dollar we flnd that the flrst hypothesis flts the data no better than the baseline model we flnd some support for the international spillovers version of the model but the behavior of non u s central bankers with respect to domestic unemployment rates is not well described by the time inconsistency mechanism

fiscal deficits and inflation abstract macroeconomic theory postulates that persistent fiscal deficits are inflationary yet empirical research has had limited success in uncovering this relationship this paper reexamines the issue in light of broader data and a new modeling approach that incorporates two key features of the theory unlike previous studies we model inflation as non linearly related to fiscal deficits through the inflation tax base and estimate this relationship as intrinsically dynamic using panel techniques that explicitly distinguish between short and long run effects of fiscal deficits results spanning 107 countries over 1960 2001 show a strong positive association between deficits and inflation among high inflation and developing country groups but not among low inflation advanced economies

the behavior of money and other economic variables two natural experiments abstract the object of this paper is to test the performance of the quantity theory model and the related proposition of monetary neutrality in a context in which to use bernanke s phraseology money move d for reasons that were plausibly unrelated to the current state of the economy we investigate this question using data from two recent episodes of monetary policy regime change the move to floating exchange rates throughout the industrialized world following the breakdown of bretton woods in the early 1970s and the shift toward less expansive monetary policy that to varying degrees took place in these countries a decade or so later the results of this exercise are highly positive the money price relationship that we observe is fully consistent with theory growth shifts in the nominal stock of money and in the price level are highly correlated and bear a one to one relation to one another growth shifts in exchange rates are significantly related both to growth shifts in relative price levels and to growth shifts in relative excess supplies of money the classical neutrality proposition in this context superneutrality in general receives strong though not totally unambiguous support

cooperation productivity and profit sharing firm specific assets generate an ex post bargaining problem over surplus division and rational workers may collude to obtain a surplus share in nonpecuniary form through restriction of effort conversely profit sharing should motivate cooperation to increase productivity when work organization facilitates interaction and horizontal monitoring since productive effort yields positive externalities to workers under contractual surplus sharing in simultaneous tobit estimates we find a strong influence of profit sharing on factor productivity in a sample of medium sized metalworking capitalist firms in west germany proxies for human capital and organizational factors were included

the time varying nairu and its implications for economic policy the nairu the unemployment rate consistent with a constant rate of inflation is estimated in this paper as a parameter allowed to vary over time value is determined in an econometric model where the inflation rate depends on its past values demand and supply shocks the nairu estimated for the gdp deflator varies over the past forty years within 5 4 to 6 5 percent its estimated value for the most recent quarter 1996 q2 is 5 6 percent the nairu has declined in recent years in response to global competition immigration other factors weakening labor s bargaining position and the rapidly declining prices of computers and other electronics

monetary policy and stagflation in the uk the volatile behavior of inflation output and interest rates in the united kingdom prior to the 1990s helps discriminate between rival explanations for the outbreak of stagflation we examine alternative hypotheses with a new keynesian model of aggregate demand and inflation determination estimated on quarterly uk data for 1959 2000 our model features is and phillips curves based on optimizing behavior and fully incorporates the distinction between detrended output and the output gap stressed by optimizing analysis using simulations of our model as well as information on the real time views of policymakers we test alternative explanations for the outbreak of inflation in the united kingdom in the 1960s and 1970s we find that inaccurate estimates of the degree of excess demand in the economy contributed significantly to the outbreak but we also find a major role for the failure at the time to recognize the importance of monetary policy as opposed to nonmonetary devices in controlling inflation

does the barro gordon model explain the behavior of us inflation a reexamination of the empirical evidence abstract this paper tests the predictions of the barro gordon model using us data on inflation and unemployment to that end it constructs a general game theoretical model with asymmetric preferences that nests the barro gordon model and a version of cukierman s model as special cases likelihood ratio tests indicate that the restriction imposed by the barro gordon model is rejected by the data but the one imposed by the version of cukierman s model is not reduced form estimates are consistent with the view that the federal reserve weights more heavily positive than negative unemployment deviations from the expected natural rate

inflation targeting under asymmetric preferences this paper develops and estimates a game theoretical model of inflation targeting where the central banker s preferences are asymmetric around the targeted rate specifically positive deviations from the target can be weighted more or less severely than negative ones in the central banker s loss function it is shown that some of the previous results derived under the assumption of symmetry are not robust to this generalization of preferences estimates of the central banker s preference parameters for canada sweden and the uk are statistically different from the one implied by the commonly used quadratic loss function

time inconsistency of monetary policy empirical evidence from polls while the basic model of time inconsistency put forward by barro and gordon barro r j gordon d b 1983 journal of political economy 91 589 610 is widely accepted now several authors have expressed serious doubts about the empirical relevance of the model in explaining inflation interestingly enough few attempts have been made so far to test for the existence of inflationary biases empirically theory predicts a positive correlation between a monetary authority s relative preference for the high employment goal and inflation using polling data from six countries as a proxy for public preferences we provide empirical evidence in favor of the barro gordon model

how important is precommitment for monetary policy we quantify the welfare differential between precommitment and discretionary monetary policy in three estimated models of the u s economy by calculating the permanent deviation of inflation from target that in welfare terms is equivalent to moving from discretion to precommitment using a range of reasonable central bank preference parameters this inflation equivalent ranges from 0 05 to 3 6 percentage points with a mid point of either 0 15 or 1 1 5 percentage points depending on the model in addition to the degree of forward looking behavior we show that the existence of transmission lags and or information lags is crucial for determining the welfare gain from precommitment

the great inflation and the greenbook abstract can the story of evolving federal reserve beliefs in the conquest of american inflation simultaneously explain the great inflation and the forecasts published in the greenbook during that time if sargent is correct then evolving beliefs should be reflected not only in policy outcomes but also in greenbook forecasts in this paper they are by conditioning on the greenbook it is show that both inflation outcomes and greenbook forecasts can be rationalised by evolving beliefs the results improve on recent empirical evidence that has been criticised for relying on unrealistic beliefs that produce forecasts inconsistent with the greenbook

establishing property rights establishing secure property rights in transition economies amounts to solving two problems inefficiency structures of control rights over assets and poor contract enforcement politicians and bureaucrats still wield excessive control over assets which results in inefficient underinvestment by entrepreneurs corruption is one way of getting around political control but the drawbacks are considerable particularly the limited enforceability of corruption contracts more workable strategies for establishing property rights in transition economies are giving equity to the bureaucrats and other parties that have control reforming the civil service and removing bureaucratic control rights through privatization russia s experience shows how privatization combined with equity incentives for enterprise insiders transfers control rights from the bureaucrats and stimulates political and economic pressures to protect private property rights

natural rate doubts abstract we study the low frequency comovements in unemployment inflation and the federal funds rate in the u s from 1970 through 1979 all three series trended up together after 1979 they all trended down the conventional explanation for the buildup of inflation in the 1970s is that the fed reacted to an increase in the natural rate of unemployment by conducting an overly passive monetary policy we show that this explanation is difficult to reconcile with the observed comovement of the fed funds rate and inflation we argue instead that the source of the inflation buildup in the 1970s was a downward drift in the real interest rate that was translated into a simultaneous increase in unemployment and inflation by passive fed policy our explanation relies on the existence in the data of a positive long run unemployment inflation relationship this is consistent with non superneutrality of money in the long run and hence the title of our paper natural rate doubts

optimal monetary policy revisited does considering us real time data change things croushore 2011 and others have noted that monetary policy may be sensitive to inconsistencies between real time data available to policy makers when making their decisions and revised data which more accurately measureeconomic performance this paper extends the asymmetric preferencemodel suggested by ruge murcia 2003 in order to focus on these inconsistencies which arise because of the long lag between the real time data release and the revised data release we focus on two related monetary policy models in both models the central banker targets a weighted average of revised and real time inflation the models differ by what the second variable is in the monetary objective function with the first model using a weighted average of revised and real time output whereas the second model uses a weighted average of revised and real time unemployment our models identify several new potential sources of inflation bias due to data revisions in addition to the ones previously suggested in the literature our empirical results suggest that the federal reserve bank mainly focuses on targeting revised data for all three variables but it does weigh real time data too as a consequence the inflation bias induced by real time data increases by 12 6 basis points on average but this figure becomes roughly twice as large at the start of recessions

optimal monetary policy with asymmetric preferences for output abstract we extend ruge murcia 2003 2004 to weigh inflation and output and show that empirical evidence supports an asymmetric preference hypothesis for output we also find evidence that the monetary authority targets potential output in parallel to barro and gordon 1983

inflation starts in latin america and the caribbean high rates of inflation are a perennial problem in latin american and caribbean lac countries this article attempts to identify the factors that initiate these inflationary episodes using observations on 31 lac countries between 1970 and 2006 the study finds that the key determinants of inflation starts in the region are demand pressures oil price shocks elections transitions to less repressive political regimes and foreign inflation

a simple adaptive measure of core inflation this paper proposes a new measure of core inflation and compares it with several existing measures the new measure is adaptive and is designed to track sudden and persistent movements in inflation such as those arising from changes in monetary policy regimes the adaptive measure filters out transients more effectively than existing measures and it is a superior predictor of locally mean reverting components of inflation

what explains the great moderation in the u s a structural analysis this paper investigates what has caused output and inflation volatility to fall in the u s using a small scale structural model using bayesian techniques and rolling samples there are instabilities in the posterior of the parameters describing the private sector the policy rule and the variance of the shocks results are robust to the specification of the policy rule changes in the parameters describing the private sector are the largest but those of the policy rule and the covariance matrix of the shocks explain the changes most jel e52 e47 c53

the institutions and governance of economic development and reform why are the ambitions of economic development practitioners and reformers so often disappointed one answer is that development policymakers and reformers are congenital optimists another answer is that good plans are regularly defeated by those who occupy strategic positions an intermediate answer is that institutions are important yet are persistently neglected in the planning process the article takes a bottom up microanalytical approach to economic development and reform it examines the governance of contract investment and private ordering through the lens of transaction cost economizing and it assesses the efficacy of the de facto as against the de jure institutional environment with respect to credible commitments in effect institutional economists are cast in the role of archaeologists of economic reform and development with the task of unpacking the lessons of the past to inform choices and programs for the future

does the dynamic time consistency model of inflation explain cross country differences in inflations dynamics dynamic time consistency models of monetary policy imply that the size of the inflationary response to price shocks and the persistence of inflation is inversely related to factors that enhance the central bank s ability to commit to low average inflation hence these models predict that the dynamics of inflation vary over time and across countries in response to changes in measures of political support for low inflation we find support for this hypothesis in data fromeighteen oecd countries over the period 1961 94 however political variables account for only a small fraction of the variation in inflation dynamics across countries 2004 elsevier ltd all rights reserved

changes in the federal reserve s inflation target causes and consequences this paper estimates a new keynesian model to draw inferences about the behavior of the federal reserve s unobserved inflation target the results indicate that the target rose from 1 1 4 percent in 1959 to over 8 percent in the mid to late 1970s before falling back below 2 1 2 percent in 2004 the results also provide some support for the hypothesis that over the entire postwar period federal reserve policy has systematically translated short run price pressures set off by supply side shocks into more persistent movements in inflation itself although considerable uncertainty remains about the true source of shifts in the inflation target jel e31 e32 e52

real balance effects and monetary policy i introduction modern literature on monetary policy rules employs new keynesian optimizing models that do not explicitly include monetary aggregates see e g rotemberg and woodford 1997 clarida et al 1999 taylor 1999 in these models the demand for output derives from the log linearization of the standard euler equation characterizing household s saving decisions the real money stock does not enter the is relation and therefore monetary policy affects output and inflation only through its effect on the real interest rate when the nominal interest rate is the policy instrument it is not necessary to specify a money market equilibrium condition see romer 2000 the practice of neglecting monetary aggregates in monetary policy analysis has recently been questioned by meltzer 1999 mccallum 2001 and nelson 2002 2003 in particular mccallum 2001 points out that although no explicit term involving money appears in the standard new keynesian setup long run inflation can still be pinned down by the economy steady state nominal money growth rate moreover mccallum 2000 2001 andres et al 2001 kremer et al 2003 woodford 2003 ireland 2004a and collard and dellas 2005 analyze the case in which the resources used by consumers in conducting transactions are modeled by a nonseparable function of consumption and real money balances meltzer 1999 2001 argues that changes in real monetary base generate effects on real aggregate demand not summarized by the real interest rate on short term securities nelson 2003 emphasizes the role of money in the transmission mechanism both as a proxy for a whole spectrum of rates of return and as an indicator variable which contains information about the state of the economy the main aim of the present article is to provide additional microfoundations for an explicit role for money in the current macroeconomic debate in particular i derive a real balance effect that explicitly enters the is relation within an optimizing general equilibrium framework of the new keynesian type according to de scitovszky 1941 haberler 1946 pigou 1943 and patinkin 1965 a change in real money balances has an impact on the real financial wealth of consumers and therefore affects consumption and output notably this effect is not considered in traditional models there is in fact empirical evidence showing that real monetary base growth is a significant determinant of consumption and output gap in both the united states and in the united kingdom see chari et al 1995 meltzer 1999 nelson 2002 the present article extends the dynamic stochastic new keynesian setup with money in the utility function by introducing overlapping generations as modeled by yaari 1965 and blanchard 1985 there are good reasons to base the demand side of the economy on a discrete time stochastic monetary version of the yaari blanchard model first this kind of extension allows one to maintain the main characteristics of the so called new neoclassical synthesis that is forward looking behavior of optimizing agents and incomplete nominal adjustment of prices featured in new keynesian theories goodfriend and king 1997 second the derivation of the real balance effect does not require nonseparability in the utility function thus the implications are analytically more tractable 1 third my framework is more general because it includes the immortal representative agent setup as a particular case my analysis attempts to examine whether the presence of an explicit real balance effect in the is relation helps evaluate the role for money in designing monetary policy rules i focus on basic issues concerning the design of monetary policy rules specifically i investigate whether it is necessary for monetary policy to overreact to inflation by raising the nominal interest rate by more than the observed increase in inflation to rule out equilibrium multiplicity

labour productivity change drivers business impact and macroeconomic moderators abstract this paper focuses on the operational drivers of labour productivity changes we consider two sets of drivers a current working practices and b changes in working practices through management programs the relationship between these two sets of drivers and productivity changes are analysed we also investigate the importance of productivity growth by looking at the impact of labour productivity changes on business performance changes finally the moderating effects of industry and country on the use of drivers of productivity changes are examined data from an international survey imss iv are used for the analysis

in search of the natural rate of unemployment abstract the natural rate of unemployment can be measured as the time varying steady state of a structural vector autoregression for post war us data the natural rate implied by this approach is more volatile than most previous estimates with its movements accounting for the bulk of the variation in the unemployment rate as well as substantial portions of the variation in aggregate output and inflation these movements in turn can be related to variables associated with labor market search theory including unemployment benefits labor productivity real wages and sectoral shifts in the labor market there is also a strong negative relationship between inflation and the corresponding measure of cyclical unemployment supporting the existence of a short run phillips curve

long run impacts of inflation across sectors in a small sample of countries this article investigates the long run effects of inflation on economic output for 10 sectors of the economy with a sample of 7 countries the analysis is done using long run restrictions in a vector autoregression and reports long run multipliers with bootstrapped confidence bands the results suggest that some sectors seem to be affected differently than others as well as significant heterogeneity across countries the results suggest the strongest effects in the low inflation countries germany and japan as has been found in similar studies in contrast to research using growth regressions the evidence suggests a positive long run effect of inflation on output

a theory based state dependent phillips curve and its estimation to explain the existing empirical irregularity about the slope of a phillips curve this article provides a model of imperfect competition to short that the slope of a phillips curve is shock dependent we empirically apply a state space markov switching model to examine the impact of inflation surprise on the unemployment gap resulting in the state dependent phillips curve fitting quite well our empirical evidence indicates that an unexpected monetary expansion does produce effects in reducing unemployment rates and that supply shocks should not be ignored in estimating the phillips curve because they dominate demand shocks in several nonoil shock periods jel c51 e24 e52 i introduction it is well known that a downward sloping short run phillips curve implies a trade off between the inflation rate and unemployment rate however empirical findings point out that the slope of the phillips curve depends on the selected sample periods 1 does any theoretical model explain the changes in the slope of a short run phillips curve as displayed in the data can we find empirical support for our model that implies a slope changeable phillips curve to answer these questions this article provides a theoretical model implying that the slope of the phillips curve is shock dependent we then apply a state space markov switching model to investigate the empirical support of the theoretical model although a stable negative short run phillips curve is crucial for producing inflation forecasts in policy making institutions there is no general consensus about the negative slope of the phillips curve in empirical literature 2 one of the explanations to the previous empirical irregularity as suggested by king and watson 1994 is that the relationship between unemployment and inflation is shock dependent which means that the slope of a phillips curve relies on the dominance of the demand or supply shocks therefore the conventional single equation regression based on the state independent framework is not appropriate apart from neglecting the state dependent characteristic of the phillips curve there are several other drawbacks for conventional empirical studies when investigating the phillips curve first many articles assume that forecast errors of inflation are homoscedastic which is challenged in the literature the homoscedastic assumption is debatable because several studies such as engle 1983 jansen 1989 evans 1991 and brunner and hess 1993 point out significant heteroscedasticity in the u s inflation rate arch or garch type models provide estimates of how the conditional variance of inflation varies over time within a given structure and therefore they ignore the possibility of structural changes caused by changing regimes a markov switching heteroscedasticity model is an alternative that allows regime changes in the variance structure instead of applying arch type models to estimate the time varying conditional variance of inflation within a given structure this article takes into account the influence of regime changes on inflation s variance we apply the state dependent conditional heteroscedasticity approach provided by brunner and hess 1993 and evans and wachtel 1993 to estimate the forecasting errors of inflation the second drawback is a constant natural rate assumption the unemployment gap is the difference between the unemployment rate and the natural rate conventional literature assumes a constant natural rate which is challenged theoretically and empirically as stated by gordon 1997 the existence of unionization unemployment insurance programs and labor force demographics leads to a highly persistent unemployment rate we therefore assume that the unobservable natural rate is time varying and behaves in accordance with the hysteresis of unemployment rates 3 recent empirical works of a regime switching approach on the phillips curve have focused on whether the relationship between inflation and unemployment rates is nonlinear as in ferri et al

what starts inflation evidence from the oecd countries we use a pooled cross country time series framework to study the factors associated with the start of 73 inflation episodes in oecd countries since 1960 we find that policy makers pursuit of high real growthtargets and national elections were important factors in initiating inflation episodes u s inflation turns out to be a triggering event for simultaneous outbreaks of inflation across countries several other explanations for inflation starts including increases in the natural rate of unemployment oil price shocks changes in the political orientation of governments and government debt policy are not supported by the data

capital labor and the firm a study of german codetermination under the german corporate governance system of codetermination employees are legally allocated control rights over corporate assets through seats on the supervisory board that is the board of nonexecutive directors the supervisory board oversees the management board the board of executive directors approves or rejects its decisions and appoints its members and sets their salaries we empirically investigate the implications of this sort of labor participation in corporate decision making we find that companies with equal representation of employees and shareholders on the supervisory board trade at a 31 stock market discount as compared with companies where employee representatives fill only one third of the supervisory board seats we show that under equal representation management board compensation provides incentives that are not conducive to furthering shareholders interests possibly because labor maximizes a different objective function than shareholders we document that under equal representation companies have longer payrolls than their one third representation peers have finally we provide evidence that shareholders respond to the allocation of control rights to labor by linking supervisory board compensation to firm performance and by leveraging up the firm jel g32 g34

figuring out the fed beliefs about policymakers and gains from transparency in this paper i use a markov chain monte carlo algorithm to estimate a model of private sector behavior that does not feature private sector knowledge of the monetary policymaking process and instead leaves firms and households uncertain about how monetary policy is set the private sector entertains two competing views of monetary policymaking which i estimate firms and households use bayes law on a rolling data sample to distinguish between those two models i use this setup to study the evolution of beliefs about the federal reserve and the possible gains from transparency

does the time consistency problem explain the behavior of inflation in the united states abstract this paper derives the restrictions imposed by barro and gordon s theory of time consistent monetary policy on a bivariate time series model for inflation and unemployment and tests those restrictions using quarterly us data from 1960 through 1997 the results show that the data are consistent with the implications of the theory for the long run behavior of the two variables indicating that the theory can explain the initial rise and subsequent fall of inflation over the past four decades the results also suggest that the theory must be extended to account more fully for the short run dynamics that appear in the data

self fulfilling expectations and the inflation of the 1970s evidence from the livingston survey abstract using survey data on expectations we examine whether the response of monetary policy to sudden movements in expected inflation contributed to the persistent high inflation of the 1970s the evidence suggests that prior to 1979 the fed accommodated temporary shocks to expected inflation which then led to persistent increases in actual inflation we do not find this behavior in the post 1979 data among commonly cited factors oil and fiscal shocks do not appear to have triggered an increase in expected inflation that eventually resulted in higher actual inflation

interpreting the wage gap estimate from selectivity correction techniques using micro data abstract the selectivity correction techniques lead to two conceptually different wage gap estimates including the selectivity correction factors in the computation of the wage gap leads to a conditional estimate whereas excluding them leads to a potential estimate

behind the market stage where real societies exist part i the role of public and private order institutions this two part article is an attempt to clarify the social conditions upon which the viability and efficiency of the market system rest it strives to show that the embeddedness thesis that is an explanation based upon the existence of long run personal ties involving the use of reputation mechanisms among transactors cannot fully elucidate the question as to how the problem of trust is solved in market societies as explained in part i there are difficulties of both theoretical and empirical historical kinds and these explain why the market order needs to be sustained by private and public order institutions in part ii the role of generalised morality in backing or supplementing such institutions is discussed in the light of game theory and particular emphasis is put on the ability of moral norms to sustain honest behaviour by generating the right kind of preferences and establishing trust the vexed problem of the dynamics of norm emergence and erosion is then addressed with a view to showing

monetary policy and policy credibility theories and evidence within the past decade there has been a significant shift in attitude by many western industrialized countries toward the objectives and conduct of national economic policy the events of the 1970s accelerating inflation and stagnant economic growth motivated the view that inflation had created its own stubborn self sustaining momentum that either was not amendable to the influences of conventional macroeconomic policy or else would yield to such influences only at unacceptable costs this led to the development of a program aimed at reestablishing control over prices while minimizing any adverse consequences of anti inflationary policies on output and employment seen as a new monetary experiment the essential ingredients included prudent financial management abstinence from discretionary intervention commitment to intermediate targets and above all prior announcement of these policies evidence of this program and its effects can be found oni the continents of europe north america and latin america and provide further important lessons in anti inflationary management this paper is a survey of recent theoretical developments in monetary policy which among other issues attempt to explain one rationale for this program and the likely consequences thereof to the extent that the new program of monetary and fiscal reform was deliberately made public and impressed upon citizens as an overriding commitment of governments in advance of its execution reflects a prevailing opinion that economic policies are more effective if they are credible to private economic agents this view emphasized forcefully by william fellner 1976 1979 may be seen as being mainly due to the assimilation of the rational expectations hypothesis

discretionary monetary policy and inflation persistence rational expectations models of staggered price wage contracts have failed to replicate the observed persistence in inflation and unemployment during disinflationary periods the current literature on this persistency puzzle has focused on augmenting the nominal contract model with imperfect credibility and learning in this paper i re examine the persistency puzzle by focusing on the discretionary nature of monetary policy i show that when the central bank is allowed to re optimize a quadratic loss function each period imperfect credibility and learning even in the absence of staggered contracts can generate a significant amount of inflation persistence and employment losses during a disinflationary period

inflation investment and growth a money and banking approach output growth investment and the real interest rate in long run evidence tend to be negatively affected by inflation theoretically inflation acts as a human capital tax that decreases output growth and the real interest rate but increases the investment rate opposing evidence this paper resolves this puzzle by requiring exchange for investment as well as consumption inflation then decreases the investment rate and still decreases both output growth and real interest up to some moderately high rate of inflation above which increasingly low investment finally causes capital to fall relative to labour and the real interest rate to rise

on the choice of incentives in firms abstract simple models of individual and group incentives under uncertainty are compared and comparative performance is shown to depend upon various exogenous parameters the incentive effects of profit sharing will thus vary with organizational and other characteristics that may be difficult to observe and attempts to quantify productivity effects that neglect selection bias are likely to be misspecified significant selection effects are found in previously used firm level data and productivity effects of existing profit sharing are found to be much larger than potential effects in firms without sharing arrangements this throws doubt on policies to encourage sharing in isolation

economic returns to social power merchants finance and interlinkage in the grain markets of bangladesh abstract the paper describes contrasting forms of interlinked transaction and the exchange regimes in which they are situated in two rural areas of bangladesh a fast growing green revolution area and a slow growing backward area some interlinkages fix output and finance prices for producers others establish personalized monopsony in trade the implication for rates of return and vulnerability of the different forms of interlinked transaction are explored perverse risk transfer from less to more vulnerable parties is found particularly when interlinkages are combined the market structures described appear to emerge not from government intervention but from the uneven distribution of local power and are thus unlikely to be improved by structural adjustment reforms or by price focused policies

the evolution of u s monetary policy 2000 2007 abstract a vector autoregression with time varying parameters is used to characterize changes in federal reserve policy that occurred from 2000 through 2007 and describe how they affected the performance of the u s economy declining coefficients in the model s estimated policy rule point to a shift in the fed s emphasis away from stabilizing inflation over this period more importantly however the fed held the federal funds rate persistently below the values prescribed by this rule under this more discretionary policy inflation overshot its target and the funds rate followed a path reminiscent of the stop go pattern that characterized fed behavior prior to 1979

testing for optimal monetary policy via moment inequalities the specification of an optimizing model of the monetary transmission mechanism requires selecting a policy regime commonly commitment or discretion in this paper we propose a new procedure for testing optimal monetary policy relying on moment inequalities that nest commitment and discretion as two special cases the approach is based on the derivation of bounds for in ation that are consistent with optimal policy under either policy regime we derive testable implications that allow for specification tests and discrimination between the two alternative regimes the proposed procedure is implemented to examine the conduct of monetary policy in the united states economy

unemployment benefits as a substitute for a conservative central banker in the many years since their introduction positive theories of inflation have rarely been tested this paper documents a negative relationship between inflation and the welfare state proxied by the parameters of the unemployment benefit program that is to be expected in such theories because unemployment benefits make the monetary authority less concerned about the plight of the unemployed building a welfare state has a similar effect to appointing a conservative central banker the relationship holds in a panel of 20 oecd countries over the period 1961 1992 a region where romer finds no evidence of commitment problems it holds controlling for country and time fixed effects country specific time trends other covariates and using a decadal panel interpreted as causal the estimated effect is economically large a 1 standard deviation decrease in benefit duration is predicted to add 1 4 percentage points onto inflation or 31 of the standard deviation in inflation

hysteresis in unemployment fact or fiction abstract a stylized fact of european unemployment dynamics is one of extreme persistence and possible unit root behavior this has led to a major reconsideration of the natural rate paradigm we apply the kalman filter to estimate the natural rate of unemployment for germany and france when the moving natural rate model is tested against the alternative of a unit root process the unit root hypothesis is resoundingly rejected

expectation horizon and the phillips curve the solution to an empirical puzzle estimates of the slope of the phillips curve reported in the literature cover a range from roughly 0 6 to zero depending on specification forward looking specifications favored by theory produce the smallest slope estimates this paper addresses this puzzle by studying the bivariate process of inflation and unemployment in a fairly general unobserved components framework allowing for stochastic trends and related cycles analysis reveals that the slope of the implied phillips curve will depend critically on the horizon of the forward looking inflation expectation provided the cyclical component of unemployment is highly persistent empirical analysis results show that is the case suggesting that the choice of expectation horizon generally set at one quarter in the new keynesian literature may play an important role in this debate copyright 2007 john wiley sons ltd

ireland and switzerland the jagged edges of the great inflation abstract ireland and switzerland both had rising inflation during the early 1970s but their experiences diverged thereafter so that they form a rare example of two countries whose inflation rates are poorly correlated with one another over the great inflation period this paper proposes that the monetary policy neglect hypothesis can account for both countries experiences extensive archival evidence is considered for each country regarding the doctrines that guided 1970s policymaking this evidence establishes that switzerland s better record is accounted for by the competition between monetary and nonmonetary views of inflation being resolved earlier and more decisively in favor of the monetary view in ireland by contrast nonmonetary views of inflation dominated policymaking throughout the 1970s

profit sharing and the financial performance of companies evidence from u k panel data this paper examines the dynamic relationship between profit sharing and profitability in a sample of u k firms during the 1980s the estimates indicate a positive short run effect of the introduction of profit sharing schemes on the financial performance of companies this relationship is evident even if unobserved firm specific fixed effects and potential endogeneity of profit sharing are controlled for quite apart from its widely recognized influence on productivity and industrial relations profit sharing is arguably a financially attractive option for firms there is also evidence of the persistence of profitability in u k profit sharing firms copyright 1994 by royal economic society

why inflation rose and fell policy makers beliefs and u s postwar stabilization policy this paper provides an explanation for the run up of u s inflation in the 1960s and 1970s and the sharp disinflation in the early 1980s which standard macroeconomic models have difficulties in addressing i present a model in which rational policymakers learn about the behavior of the economy in real time and set stabilization policy optimally conditional on their current beliefs the steady state associated with the self confirming equilibrium of the model is characterized by low inflation however prolonged episodes of high inflation ending with rapid disinflations can occur when policymakers underestimate both the natural rate of unemployment and the persistence of inflation in the phillips curve i estimate the model using likelihood methods the estimation results show that the model accounts remarkably well for the evolution of policymakers beliefs stabilization policy and the postwar behavior of inflation and unemployment in the united states

recession aversion output and the kydland prescott barro gordon model abstract this paper explores the relationship between the kydland prescott barro gordon model and models with asymmetric policy preferences while both yield an inflation bias recession aversion dampens the output effects of contractionary supply shocks some inflation may therefore reflect policy preferences

macroeconomic stability and the preferences of the fed a formal analysis 1961 98 the rate of inflation in the u s has declined from an average of 4 5 in the period 1960 79 to an average of 3 6 in 1980 98 between those two periods the standard deviations of inflation and the output gap have also declined these facts can be attributed to the interaction of three possible factors a shift in central bank preferences a reduction in the variability of aggregate supply shocks and a more efficient conduct of monetary policy in this paper we identify the relative roles of these factors our framework is based on the estimation of a small structural macro model for the u s economy jointly with the first order conditions which solve the intertemporal optimization problem faced by the fed overall our results indicate that the policy preferences of the fed and in particular the implicit inflation target have changed drastically with the advent of the volcker greenspan era in addition we find that the variance of supply shocks has been lower and monetary policy has been conducted more efficiently during this period

shocks and government beliefs the rise and fall of american inflation working paper 2004 22 september 2004 abstract the authors use a bayesian markov chain monte carlo algorithm to estimate a model that allows temporary gaps between a true expectational phillips curve and the monetary authority s approximating nonexpectational phillips curve a dynamic programming problem implies that the monetary authority s inflation target evolves as its estimated phillips curve moves the authors estimates attribute the rise and fall of post world war ii inflation in the united states to an intricate interaction between the monetary authority s beliefs and economic shocks shocks in the 1970s altered the monetary authority s estimates and made it misperceive the tradeoff between inflation and unemployment that misperception caused sharp rise in inflation in the 1970s the authors estimates indicate that policy makers updated their beliefs continuously by the 1980s policy makers beliefs about the phillips curve had changed enough to account for fed chairman paul volcker s conquest of u s inflation in the early 1980s jel classification e3 e5 key words updating beliefs policy evaluation self confirming equilibrium nash inflation ramsey outcomes i introduction today many statesmen and macroeconomists believe that inflation can largely be determined by a government monetary authority then why did the federal reserve board preside over high us inflation during the late 1960s and the 1970s and why under paul volcker did it rapidly bring inflation down during the early 1980s this paper answers these questions by estimating a model that features a particular process that makes a procession of economic shocks induce the monetary authority to alter its model of inflation unemployment dynamics the phillips curve at each date t the monetary authority updates its beliefs about the phillips curve and then recomputes a first period action recommended by a phelps problem a discounted dynamic programming problem that minimizes the expected value of a discounted quadratic loss function of inflation and unemployment 1 the monetary authority pursues the same objectives at each date using the same structural model with only its estimates of that model changing over time 2 this model of the systematic part of inflation puts the monetary authority s beliefs about the phillips curve front and center 3 we assume that the monetary authority s model of the phillips curve deviates in two subtle but important ways from what it would be in a rational expectations model e g kydland and prescott 1977 the first deviation is that while the true phillips curve is like kydland and prescott s we assume that the monetary authority omits the public s expected rate of inflation from its phillips curve by itself this omission need not prevent the outcomes of our model from coinciding with those of kydland and prescott s nor need it imply that the government s model is wrong in a way that could be detected from even an infinite sample whether the monetary authority s model is wrong in a statistically detectable way depends on how we allow the monetary authority to reestimate the parameters of its model in particular if the monetary authority were to believe that the coefficients of its phillips curve are constant over time then its estimates would converge to ones that support a self confirming equilibrium sce after convergence its estimated phillips curve would correctly describe occurrences along the sce path for inflation and unemployment such an after convergence version of our model has little hope of explaining the rise and fall of us inflation that model would have inflation fluctuating randomly around a constant sce level that coincides with kydland and prescott s time consistent suboptimal i e excessive level 4 this outcome motivates our second subtle deviation from a rational expectations equilibrium
