does sports activity improve health representative evidence using local density of sports facilities as an instrument abstractusing representative and geocoded data from the swiss household panel and the swiss business census we estimate the effect of sports activity on health ols models show that sports activity significantly decreases overweight sleeping problems headaches back problems and perceived health impediments in everyday activities and significantly increases health satisfaction because sports activity is likely to be misreported and correlated with unobserved determinants of health we use the number of sports facilities within 6 miles of the individual s residence as an instrument for sports activity although the instrument is powerful in explaining sports activity the second stage effects on health are mostly statistically insignificant due to the high ses of the iv estimates

stabilization policy a reconsideration i introduction in 1936 keynes s general theory explained how fiscal and monetary policy could be used to end depressions since that time no developed country has ever seen a downturn on the scale of the 1930s the general theory was not just a how to book on the avoidance of depressions it was an argument for stabilization policy itself the years since the general theory have seen a revolt against keynesian economics in a revisionist mode milton friedman argued that countercyclical policy cannot affect the average level of unemployment and output robert lucas and thomas sargent 1979 went further contending that it is not only impossible to increase average output it is also impossible to stabilize it more recently lucas 1987 2003 has argued that policies to stabilize output even if effective would yield negligible welfare gains thus stabilization policy should not be a macroeconomic priority lucas s conclusion notwithstanding stabilization policy has long been an explicit or implicit objective of monetary policy in most industrial countries even including those countries with inflation targets the volatility of output has in fact declined in most major industrial countries since the mid 1980s and monetary policy arguably deserves at least partial credit see bernanke 2004 mirroring practice monetary policy research commonly takes it as given that along with price stability stabilization policy the minimization of squared deviations of output around potential is an appropriate policy objective see for example clarida et al 1999 in this article we explore the economic rationale for stabilization as a policy goal concluding that it does in fact deserve high policy priority we survey a large body of literature that critiques the validity of key assumptions in lucas s argument we also offer suggestive evidence that stabilization policy can significantly reduce average levels of unemployment by providing stimulus to demand in circumstances where unemployment is high but underutilization of labor and capital does little to lower inflation a monetary policy that vigorously fights high unemployment should however also be complemented by a policy that equally vigorously fights inflation when it rises above a modest target level the federal reserve act thus wisely enunciated price stability and maximum employment as twin goals for monetary policy ii the case against stabilization policy macroeconomic analysis typically assumes that social welfare depends negatively on both inflation above a modest target level here assumed zero and unemployment above some minimum socially efficient level for example a standard social welfare function is the discounted sum of period losses l sub t of the form see among others barro and gordon 1983 pp 592 93 1 l sub t a u sub t 1 k u sup 2 b pi sup 2 sub t where u sub t and pi sub t are the unemployment and inflation rates in period t and u sup is the natural rate of unemployment the coefficient k is positive reflecting the desirability of unemployment below the natural rate because real economies deviate in many respects from perfect competition the natural rate of unemployment is likely to exceed the socially optimal unemployment rate for example with monopolistic competition goods are underproduced because they are priced above marginal cost so potential output is inefficiently low and equilibrium unemployment is too high standard macroeconomic analysis additionally assumes that inflation is determined by an expectations augmented accelerationist phillips curve of the form 2 pi sub t pi sup e sub t f u sub t u sup epsilon sub t where pi sup e sub t is the expected inflation rate at time t with expectations formed at t 1 and epsilon sub t captures supply shocks to the phillips curve at t

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 output composition puzzle a difference in the monetary transmission mechanism in the euro area and u s we revisit recent evidence on how monetary policy affects output and prices in the u s and in the euro area the response patterns to a shift in monetary policy are similar in most respects but differ noticeably as to the composition of output changes in the euro area investment is the predominant driver of output changes while in the u s consumption shifts are significantly more important we dub this difference the output composition puzzle and explore its implications and several potential explanations for it while the evidence seems to point at differences in consumption responses rather than investment as the proximate cause for this fact the source of the consumption difference remains a puzzle

the inexorable and mysterious tradeoff between inflation and unemployment this paper discusses the short run tradeoff between inflation and unemployment although this tradeoff remains a necessary building block of business cycle theory economists have yet to provide a completely satisfactory explanation for it according to the consensus view among central bankers and monetary economists a contractionary monetary shock raises unemployment at least temporarily and leads to a delayed and gradual fall in inflation standard dynamic models of price adjustment however cannot explain this pattern of responses reconciling the consensus view about the effects of monetary policy with models of price adjustment remains an outstanding puzzle for business cycle theorists several years ago i gave myself a peculiar assignment i decided to try to summarise all of economics in ten simply stated principles the purpose of this task was to introduce students to the economic way of thinking in the first chapter of my textbook principles of economics i figured if god could boil all of moral philosophy down to ten commandments i should be able to do much the same with economic science most of the ten principles i chose were microeconomic and hard to argue with they involved the importance of tradeoffs marginal analysis the benefits of trade market efficiency market failure and so on i allocated the last three principles to macroeconomics the first of these was a country s standard of living depends on its ability to produce goods and services which i viewed as the foundation of all growth theory the second was prices rise when the government prints too much money which i took to be the essence of classical monetary theory the last of my ten principles is the subject of today s lecture society faces a short run tradeoff between inflation and unemployment perhaps not surprisingly this statement turned out to be controversial when my publisher sent out the manuscript for review a few readers objected

disinflation with imperfect credibility abstract this paper presents a theory of the real effects of disinflation as in new keynesian models price adjustment iis staggered across firms as in new classical models credibility is imperfect the monetary authority may not complete a promised disinflation the combination of imperfect credibility and staggering yields more plausible results than either of these assumptions alone in particular an announced disinflation reduces expected output if credibility is sufficiently low

state dependent pricing and the dynamics of money and output standard macroeconomic models of price stickiness assume that each firm leaves its price unchanged for a fixed amount of time we present an alternative model in which the pricing decision depends on the state of the economy we find a method of aggregating individual price changes that allows a simple characterization of macroeconomic variables the model produces a positive money output correlation and an empirical phillips curve in addition the impact of monetary shocks depends crucially on the current level of output which points to a natural connection between state dependent microeconomics and state dependent macroeconomics i introduction there is a long tradition in macroeconomics of attributing the real effects of nominal demand shocks to nominal price stickiness in this view if there is no change in prices when nominal demand rises then quantities must bear the burden of adjustment hence nominal price rigidity provides the friction needed for nominal demand shocks to be transmitted to the real economy standard models of this transmission mechanism such as fischer 1977 and taylor 1980 are based on the assumption that each firm leaves its price unchanged for a fixed amount of time the main reason for considering such time dependent pricing rules is their analytic tractability constraining firms to adjust their prices at prespecified times both simplifies the derivation of equilibrium strategies and allows the use of powerful time series techniques to analyze aggregate dynamics the main disadvantage of the timedependent approach is that between price adjustments firms are not allowed to respond even to extreme changes of circumstance this makes it difficult to know whether the qualitative effects of money in these models are the result of nominal rigidities per se or of the exogenously imposed pattern of price changes an alternative approach to modeling price stickiness is to allow the price setting decision to depend on the actual state of the

a critical reconsideration of the foundations of monetary policy in the new consensus macroeconomics framework monetary policy has become firmly based on the use of interest rate as the key policy instrument and in a one instrument one target framework the approach to monetary policy is closely associated with the new consensus in macroeconomics ncm this paper undertakes a critical appraisal of the role of monetary policy in the context of the ncm after setting out the main features of the ncm there is critical discussion of the role of monetary policy and the ncm framework the discussion covers the nature of the loss function the role of the natural rate of interest and the phillips curve this is followed by a critical evaluation of the is curve in the ncm and the classical dichotomy the paper finishes by asking whether interest rates do have the effects claimed for them

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

assessing sticky price models using the burns and mitchell approach this article evaluates sticky price models using the methods proposed by burns and mitchell focusing on the monetary aspects of the business cycle recent research has emphasized the responses of models to shocks at the expense of its systematic component whereas sticky price models have been successful at replicating impulse response functions from vector autoregressions this article highlights that they are unable to mimic the data for nominal variables moreover the results are robust to the specification of the phillips curve including its backward looking variant calibrated values and the inclusion of fiscal policy shocks since being able to mimic the data is the lowest hurdle a model must pass these results pose a challenge for sticky price models

the intention to move and residential location choice behaviour this paper aims to quantify the extent to which transport and other factors impact on residential decisions using oxfordshire uk as a case study it investigates the impacts of the current dwelling household characteristics and alternative properties on the probability of moving it also highlights the trade off between access space and other attributes in residential location choice particular emphasis is placed on assessing the impact of transport and location embedded amenities a nested logit model is applied to estimate the indirect random utility functions of the intention to move and residential location choice based on stated preference data the estimation results of the intentions to move model illustrate the impact of housing and household characteristics on the probability of moving the estimation results of the residential location choice model quantify the trade offs between transport amenities and other factors

long run labour market and health effects of individual sports activities abstract this microeconometric study analyzes the effects of individual leisure sports participation on long term labour market variables health and subjective well being indicators for west germany based on individual data from the german socio economic panel study gsoep 1984 2006 econometric problems due to individuals choosing their own level of sports activities are tackled by combining informative data and flexible semiparametric estimation methods with a specific way to use the panel dimension of the data the paper shows that sports activities have sizeable positive long term labour market effects in terms of earnings and wages as well as positive effects on health and subjective well being

elusive persistence wage and price rigidities the new keynesian phillips curve and inflation dynamics abstract we review the main new keynesian inflation equations that have arisen as a result of aggregation from individual firms price rigidities we find that on the whole they cannot account for inflation persistence a key feature of the empirical dynamics of inflation and with important policy implications the only exceptions seem to be when indexation is allowed in price setting or when price stickiness is combined with wage rigidity and staggering

fairness and inflation persistence we argue that peoples concern for fairness may explain an unsolved puzzle in macroeconomics the persistence of ine ation we extend a 1990 wage contracting model of bhaskar in which workers disutility from being paid less than other workers exceeds their utility from being paid more this model generates a continuum of equilibria over a range of wages and unemployment rates if workers expectations are based on the past behavior of wage growth these beliefs will be self fule lling generating ine ation persistence within but not outside of this range based on quarterly u s data over the period 1955 2000 we e nd evidence that ine ation is more persistent between unemployment rates of 4 7 and 6 5 than outside these bounds jel e31 e3 e5

fear of floating and the external effects of currency unions the introduction of the euro has considerably affected the de facto monetary policy autonomy defined as independence from monetary policy in the key currency areas in countries outside the european currency union ecu using a standard open economy framework we argue that de facto monetary policy autonomy has significantly declined for countries that dominantly trade with the ecu and slightly increased for countries that dominantly trade with the dollar zone the predictions of our model find support in the data we estimate the influence of the bundesbank s ecb s and the fed s monetary policies on various country groups the de facto monetary policy autonomy of both non euro eu members and efta countries declined with the introduction of the euro this effect was slightly stronger for the eu member countries than for efta countries as our theory predicts at the same time the de facto monetary policy autonomy of australia and new zealand vis a vis the us dollar has moderately increased

estimates of the sticky information phillips curve for the united states mankiw and reis 2002 have proposed a sticky information based phillips curve sipc to address some of the concerns with the sticky price based new keynesian phillips curve in this paper we present a methodology to empirically implement the sipc and estimate its key structural parameter the degree of information stickiness for the united states using this methodology we estimate average durations of information stickiness that range from three quarters on the low side to over seven quarters on the high side

the new keynesian phillips curve and lagged inflation a case of spurious correlation the new keynesian phillips curve nkpc specifies a relationship between inflation and a forcing variable and the current period s expectation of future inflation most empirical estimates of the nkpc typically based on generalized method of moments gmm estimation have found a significant role for lagged inflation producing a hybrid nkpc using u s quarterly data this article examines whether the role of lagged inflation in the nkpc might be due to the spurious outcome of specification biases like previous investigators we employ gmm estimation and like those investigators we find a significant effect for lagged inflation we also use time varying coefficient tvc estimation a procedure that produces consistency under a variety of sources of misspecification using two separate measures of expected inflation we find strong support for the view that under tvc estimation the coefficient on expected inflation is near unity and that the role of lagged inflation in the nkpc is spurious

hyperbolic discounting and the phillips curve using a standard dynamic general equilibrium model we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long run effects on real variables

inflation and output in new keynesian models with a transient interest rate peg a familiar result in the canonical dynamic new keynesian dnk model is that policymakers constrained by the zero bound can improve outcomes by promising to keep rates low after the zero bound is not binding we examine a general class of interest rate pegs in a variety of dnk models standard versions of the model produce counterintuitive reversals where the effect of the interest rate peg can switch from highly expansionary to highly contractionary for modest changes in the length of the interest rate peg this unusual behavior does not arise in sticky information models of the phillips curve

a quick refresher course in macroeconomics this paper presents a non technical discussion of some of the important developments in macroeconomics over the past twenty years it considers three broad categories of research first it discusses how the notion of rational expectations has affected economists views on the role of economic policy the debate over rules versus discretion and empirical work in macroeconomics second it discusses various new classical approaches to the business cycle including imperfect information theories real business cycle theories and sectoral shift theories third it discusses various new keynesian approaches to the business cycle includes theories based on general disequilibrium labor contracting and menu costs this abstract was borrowed from another version of this item

is inflation sticky abstract new keynesian sticky price models predict that monetary policy can affect real variables however they also predict that inflation can be reduced without depressing output or employment in fact bringing down inflation is costly presenting a challenge to the new keynesian model two departures from the new keynesian model predict costly disinflation one assumes sticky inflation rather than sticky prices while the other assumes less than perfectly rational expectations taking into account information from surveys of inflation expectations i find the evidence suggests that inflation is not sticky and that inflation expectations are less than perfectly rational

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

inflation inertia and credible disinflation abstract we develop a model of optimizing forward looking staggered price setting where even fully credible disinflations display a delayed and gradual inflation response and significant output losses there is a welfare trade off between these output losses and the gains from smaller inflationary distortions for reasonable parameter values disinflation improves welfare and more so if it is phased in gradually the pricing assumption of our model yields dynamics that are similar to models of sticky information but its state space is much simpler thereby allowing for the application of standard linearization methods

monetary policy for inattentive economies we offer a contribution to the analysis of optimal monetary policy we begin with a critical assessment of the existing literature arguing that most work is based on implausible models of inflation output dynamics we then suggest that this problem may be solved with some recent behavioral models which assume that price setters are slow to incorporate macroeconomic information into the prices they set a specific such model is developed and used to derive optimal policy in response to shocks to productivity and aggregate demand optimal policy is price level targeting base drift in the price level which is implicit in the inflation targeting regimes currently used in many central banks is not desirable in this model when shocks to desired markups are added optimal policy is flexible targeting of the price level that is the central bank should allow the price level to deviate from its target for a while in response to these supply shocks but it should eventually return the price level to its target path optimal policy can also be described as an elastic price standard the central bank allows the price level to deviate from its target when output is expected to deviate from its natural rate

a comprehensive short run analysis of a possible turkish phillips curve the studies on phillips curves relating the rate of unemployment to the rate of inflation are the results of the search for a reliable tool for forecasting inflation and implementing monetary policy the original phillips curve has attracted considerable attention and since then it has undergone several important changes although the evidence of a negative relationship between the rate of change in a money variable and unemployment rate has not been proven it is still considered to be critical for policymaking and is on researchers agenda niskaken 2002 the existence of a phillips curve for turkey is investigated with the linear and non linear specifications for the conventional and new keynesian phillips curves with inflation expectations and natural rate of unemployment for annual 1980 2001 and semiannual 1988 2 2003 1 data sets the results indicate no evidence of a phillips curve for all specifications and both data sets the semiannual data seems to have a better fit in all specifications

robust monetary policy in a small open economy abstract we study how a central bank in a small open economy should conduct monetary policy if it fears that its model is misspecified using a new keynesian model of a small open economy we solve analytically for the optimal robust policy rule and the equilibrium dynamics and we separately analyze the consequences of central bank robustness against misspecification concerning the determination of inflation output and the exchange rate we show that an increase in the preference for robustness makes the central bank respond more aggressively or more cautiously to shocks depending on the type of shock and the source of misspecification

monetary policy for an open economy an alternative framework with optimizing agents and sticky prices the new open economy macroeconomics seeks to provide an improved basis for monetary and exchange rate policy through the construction of open economy models that feature rational expectations optimizing agents and slowly adjusting prices of goods this paper promotes an alternative approach for constructing such models by treating imports not as finished consumer goods but rather as raw material inputs to the home economy s productive process this treatment leads to a clean and simple theoretical structure that has some empirical attractions as well a particular small economy model is calibrated and its properties exhibited primarily by means of impulse response functions the preferred variant is shown to feature a pattern of correlations between exchange rate changes and inflation that is more realistic than provided by a more standard specification important recent events are interpreted in light of the alternative models

when did unsystematic monetary policy have an effect on inflation abstract an important stylized fact to emerge from var estimates is that exogenous monetary policy shocks also labelled unsystematic monetary policy have a delayed persistent hump shaped effect on inflation i argue that this empirical pattern is fragile in particular it disappears when one examines periods without large shifts in the level of inflation such as 1984 2005 an important consequence is that the hump shaped var estimated response of inflation is not appropriate to fit stylized models of the response of inflation around a stable steady state inflation level

a near rational model of the business cycle with wage and price inertia this paper presents a model in which insignificantly suboptimal behavior causes aggregate demand shocks to have significant real effects the individual loss to agents with inertial price wage behavior is second order in terms of the parameter describing the shock while the effect on real economic variables is first order thus significant changes in business activity can be generated by anticipated money supply changes provided that some agents are willing to engage in nonmaximizing behavior which results in small losses

estimating potential output core inflation and the nairu as latent variables this article proposes a new method to obtain estimates of the nairu the core inflation rate and the trend investment rate for the united states using an unobserved components model that is compatible with the usual decomposition of real gross domestic product into trend and cycle the model includes okun s law a forward looking phillips curve and an accelerator type investment equation and accounts for some volatility breaks in two components the unknown parameters in the model are estimated by maximum likelihood using a kalman filter initialized with a partially diffuse prior and the unobserved components are estimated using a smoothing algorithm our results show that the output gap is positively correlated with the deviations of the investment rate from its trend and the inflation rate from core inflation and negatively correlated with the deviations of the unemployment rate from the nairu

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

real wage rigidities and disinflation dynamics calvo vs rotemberg pricing abstract calvo pricing implies output gains while rotemberg pricing implies output losses after a disinflation introducing real wage rigidities has opposite effects it generates a long lasting boom in output in calvo and a moderate output slump in rotemberg

the history of the phillips curve consensus and bifurcation while the early history of the phillips curve up to 1975 is well known less well understood is the post 1975 fork in the road the left fork developed a theory of policy responses to supply shocks in the context of price stickiness in the non shocked sector its econometric implementation interacts shocks with backward looking inertia the right fork approach emphasizes forward looking expectations that can jump in response to anticipated policy changes the left fork approach is better suited to explaining the postwar us inflation process while the right fork approach is essential for understanding behaviour in economies with unstable macroeconomic environments the history of the phillips curve pc has evolved in two phases before and after 1975 with a widespread consensus about the pre 1975 evolution which is well understood bifurcation begins in 1975 when the pc literature split down two forks of the road with little communication or interaction between the two forks the major contribution of this paper and hence the source of bifurcation in its subtitle is to examine contrast and test the contributions of the two post 1975 forks the pre 1975 history is straightforward and is covered in section i the initial discovery of the negative inflation unemployment relation by phillips popularized by samuelson and solow was followed by a brief period in which policy makers assumed that they could exploit the trade off to reduce unemployment at a small cost of additional inflation then the natural rate revolution of friedman phelps and lucas overturned the policy exploitable trade off in favour of long run monetary neutrality those who had implemented the econometric version of the trade off pc in the 1960s reeled in disbelief when sargent demonstrated the logical failure of their test of neutrality and finally were condemned to the wreckage of keynesian economics by lucas and sargent following the twist of the inflation unemployment correlation from negative in the 1960s to positive in the 1970s the architects of neutrality and the opponents of the keynesian trade off emerged triumphant with two major caveats that their own models based on information barriers were unconvincing and that their core result that business cycles were driven by monetary or price surprises floundered without supporting evidence after 1975 the evolution of the pc literature split in two directions each of which has largely failed to recognize the other s contributions section ii reviews the left fork of the road the revival of the pc trade off in a coherent and integrated dynamic aggregate supply and demand framework that emerged in the late 1970s in econometric tests in theoretical contributions and in intermediate macro textbooks this approach which i have called mainstream is resolutely keynesian because the inflation rate is dominated by persistence and inertia in the form of long lags on past inflation an important difference between the mainstream approach and other post 1975 developments is that the role of past inflation is not limited to the formation of expectations but also includes a pure persistence effect due to fixed duration wage and price contracts and lags between

trend inflation and firms price setting rotemberg versus calvo we compare the calvo and rotemberg price setting mechanisms in a new keynesian model with trend inflation we show that the long run relationship between inflation and output is positive in rotemberg and negative in calvo the dynamics of the two models differ even to a first order approximation positive trend inflation enlarges the determinacy region in the rotemberg model whereas it shrinks it in the calvo model the responses of output and inflation to technology shocks are amplified by trend inflation in calvo whereas they are dampened in rotemberg the two models imply differing non linear adjustments after a disinflation

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

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

inflation targeting in emerging economies panel evidence abstract this paper shows there is no evidence that the inflation targeting regime it improves economic performance as measured by the behavior of inflation and output growth in developing countries the control of common time effects results in less negative and less significant it impacts on inflation inflation volatility and output growth volatility than previously found in the literature additionally our analysis shows robust evidence of lower output growth during it adoption on balance although lower long run mean inflation signals that the central banks of emerging economies with inflation targeting are more inflation averse the costs of disinflation have not been lower than under other monetary regimes

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

a survey of new keynesian theories of aggregate supply and their relation to industrial organization i survey the recent literature on the phillips curve along the way i will try to relate this literature to topics of interest to industrial organization i will also point out the gaps in our understanding and places where more careful micro economic analysis would be helpful to macroeconomists in the conclusion i summarize what an industrial organization economist might take away from this literature

monetary policy endogenous inattention and the volatility trade off this paper addresses the output price volatility puzzle by studying the interaction of optimal monetary policy and agents beliefs we assume that agents choose their information acquisition rate by minimizing a loss function that depends on expected forecast errors and information costs endogenous inattention is a nash equilibrium in the information processing rate although a decline of policy activism directly increases output volatility it indirectly anchors expectations which decreases output volatility if the indirect effect dominates then the usual trade off between output and price volatility breaks down this provides a potential explanation for the great moderation that began in the 1980 s

is there a core of practical macroeconomics that we should all believe with emphasis on the adjective practical and the normative verb should my answer to the question of this session is a resounding yes indeed i spent a good deal of time between january 1993 and january 1996 acting on the belief that there is such a core macro model so i certainly hope it exists this believable core model falls well short of perfection leaves many questions unanswered and is subject to substantial stochastic errors nonetheless it is both useful and extensively used in policy analysis where contact with reality is a necessity and you cannot beat something with nothing it also closely resembles but does not quite match the way macroeconomics is taught to beginning and intermediate but not to graduate students in this short presentation i will describe briefly the main practical elements that i think we should agree on without worrying too much about their theoretical underpinnings then i will turn to two critical failings of the standard macro model which cry out for theoretical and empirical repair my organizing principle is the textbook exposition that has been standard though not universal in teaching intermediate macroeconomics for years the question is how does it differ from the core model used in policy analysis

a sectoral analysis of price setting behavior in us manufacturing industries abstract in this paper we estimate new keynesian phillips curves nkpc for u s manufacturing industries defined at the sic two digit level over the period 1959 to 1996 this enables us to measure the extent of nominal inertia across industrial sectors a key innovation in this research is the use of intermediate goods costs rather than labor costs as a measure of marginal costs intermediate goods costs are a more significant element of costs for the firms populating our sample and are not subject to the criticism that wage rates are nonallocative we find that there is statistically significant variability in estimates of price stickiness ranging from eight months to two years we also find that estimates of backward looking price setting behavior vary with some industries characterized by 81 of pricing decisions made in a purely forward looking manner while in others only 52 of pricing decisions are made that way market concentration as captured by the herfindahl hirschman index appears to be

what is wrong with taylor rules using judgment in monetary policy through targeting rules it is argued that inflation targeting is best understood as a commitment to a targeting rule rather than an instrument rule e ither ageneral targeting rule explicit objectives for monetary policy or a specific targeting rule a criterion for the forecasts of the target variables to be fulfilled essentially the equality of the marginal rates of transformation and substitution between the target variables targeting rules allow the use of judgment and extramodel information are more robust and easier to verify than optimal instrument rules and they can nevertheless bring the economy close to the socially optimal equilibrium

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

on inflation and output with costly price changes a simple unifying result this paper determines the real effects of credible disinflation when price setting is staggered the results are surprising a fairly quick disinflation causes a boom this finding suggests that nominal price rigidity alone does not explain why disinflation is costly in actual economies this abstract was borrowed from another version of this item

sluggish responses of prices and inflation to monetary shocks in an inventory model of money demand we examine the responses of prices and inflation to monetary shocks in an inventory theoretic model of money demand we show that the price level responds sluggishly to an exogenous increase in the money stock because the dynamics of households money inventories leads to a partially offsetting endogenous reduction in velocity we also show that inflation responds sluggishly to an exogenous increase in the nominal interest rate because changes in monetary policy affect the real interest rate in a quantitative example we show that this nominal sluggishness is substantial and persistent if inventories in the model are calibrated to match u s households holdings of m2

is the unemployment inflation trade off still alive in the euro area and its member countries it seems so the unemployment inflation trade off can be interpreted as a proposition concerning the response of these two variables to aggregate demand shocks in this paper we study the possible presence of the trade off in the euro area and in a wide group of euroarea countries in the last 20 years i e since the start of emu we use the structural var methodology that allows the separation between supply and demand shocks our main finding is that the existence of a trade off is largely confirmed both at the euro area and at the national level nevertheless the size of the trade off measured at different horizons shows some heterogeneity among countries no less important when we augment the var model by introducing monetary policy in the context of an open economy we find that monetary policy shocks push inflation and unemployment in opposite directions in the currency area another interesting result concerns the evidence of a relatively flat relation between unemployment and inflation conditionally to monetary policy shocks

disinflation shocks in the eurozone a dsge perspective we investigate the effects of disinflation policies on key macroeconomic variables using euro area data and structural vector autoregressions svars we identify disinflation shocks as the only shocks that drive nominal variables to a lower long run level we find that in the immediate aftermath of a disinflation shock the euro area enters in a persistent recession we use these dynamic responses to estimate a dsge model with imperfect information about the disinflation shock we find that both nominal and real frictions and monetary policy gradualism have played a prominent role in the recessionary effect of disinflation shocks conversely allowing for imperfect credibility does not yield a better fit except when we shut key model s frictions down
