the predictive content of the output gap for inflation resolving in sample and out of sample evidence this paper evaluates potential explanations for the sometimes poor forecasting performance of the phillips curve one explanation is that out of sample metrics are noisy or equivalently have relatively low power another potential explanation is instability in the coefficients of the model to assess these forces this paper compares sample forecasting results to results from bootstrap simulations of models that either assume stability or allow breaks in the coefficients of the model this analysis indicates that a significant portion of the weakness of the out of sample evidence is attributable to power limitations but instabilities in the coefficients on the output gap also play a role

tracking the slowdown in long run gdp growth using a dynamic factor model that allows for changes in both the long run growth rate of output and the volatility of business cycles we document a significant decline in long run output growth in the united states our evidence supports the view that most of this slowdown occurred prior to the great recession we show how to use the model to decompose changes in long run growth into its underlying drivers at low frequencies a decline in the growth rate of labor productivity appears to be behind the recent slowdown in gdp growth for both the united states and other advanced economies when applied to real time data the proposed model is capable of detecting shifts in long run growth in a timely and reliable manner

interpreting the great moderation changes in the volatility of economic activity at the macro and micro levels most advanced economies have experienced a striking decline in the volatility of aggregate economic activity since the early 1980s volatility reductions are evident for output and employment at the aggregate level and across most industrial sectors and expenditure categories inflation and inflation volatility have also declined dramatically previous studies offer several potential explanations for this great moderation we review evidence on the great moderation in conjunction with evidence about volatility trends at the micro level we combine the two types of evidence to develop a tentative story for important components of the aggregate volatility decline and its consequences the key ingredients are declines in firm level volatility and aggregate volatility most dramatically in the durable goods sector surprisingly this has occurred without a decline in household consumption volatility and individual earnings uncertainty our explanation for the aggregate volatility decline stresses improved supply chain management particularly in the durable goods sector and less important a shift in production and employment from goods to services we provide evidence that better inventory control made a substantial contribution to declines in firm level and aggregate volatility consistent with this view if we look past the turbulent 1970s and early 1980s much of the moderation reflects a decline in high frequency short term fluctuations while these developments represent efficiency gains they do not imply nor is there evidence for a reduction in economic uncertainty faced by individuals and households

credit market constraints consumption smoothing and the accumulation of durable production assets in low income countries investments in bullocks in india in this paper we formulate and estimate a finite horizon structural dynamic model of agricultural investment behavior that incorporates the major features of low income agricultural environments income uncertainty constraints on borrowing and rental markets and the use of investment assets to generate income and smooth consumption the model is fit to longitudinal indian household data on farm profits bullock stocks and pump sets the estimated structural parameters are used to assess the effects on the life cycle accumulation of bullocks agricultural profits and welfare associated with complete markets and bullock liquidity and with second best policies that provide assured sources of income to farmers and weather insurance

endogenous objectives and the evaluation of targeting rules for monetary policy recent research in monetary economics has followed the advice of mccallum 1988 robustness properties of a rule for monetary policy carnegie rochester conference series on public policy 29 173 203 and investigated the robustness properties of monetary policy rules by evaluating them in a variety of models evaluation across models is typically based on an exogenously specified loss function however the theory on which many recent monetary policy models are based implies that changes in the structure of the model also have consequences for the policy objectives the central bank should pursue objectives are endogenous not exogenous to the model in this paper i investigate the impact of endogenous objectives on the evaluation of targeting rules for monetary policy r 2005 elsevier b v all rights reserved

developing country exports of manufactures moving up the ladder to escape the fallacy of composition this paper tests for a fallacy of composition by analysing the demand for exports of the 18 developing countries that are most specialised in manufactures in the markets of the 10 largest industrial countries estimated export equations both time series and panel data suggest that most developing countries compete with other developing country exporters rather than with industrialised country producers a smaller number of countries that export more high technology products compete with industrialised country producers and also have higher expenditure elasticities for their exports thus the fallacy of composition applies mainly to the larger group of countries exporting mostly low technology products

how robust are popular models of nominal frictions this paper analyzes three popular models of nominal price and wage frictions to determine which best ts post war u s data we construct a dynamic stochastic general equilibrium dsge model and use maximum likelihood to estimate each model s parameters because previous research nds that the conduct of monetary policy and the behavior of in ation changed in the early 1980s we examine two distinct sample periods using a bayesian pseudo odds measure as a means for comparison a sticky price and wage model with dynamic indexation best ts the data in the early sample period whereas either a sticky price and wage model with static indexation or a sticky information model best ts the data in the late sample period our results suggest that price and wage setting behavior may be sensitive to changes in the monetary policy regime if true the evaluation of alternative monetary policy rules may be even more complicated than previously believed

imperfect information and the business cycle imperfect information has played a prominent role in modern business cycle theory this paper assesses its importance by estimating the new keynesian nk model under alternative informational assumptions one version focuses on confusion between temporary and persistent disturbances another on unobserved variation in the inflation target of the central bank a third on persistent mis perceptions of the state of the economy measurement error and a fourth assumes perfect information the standard nk dsge version imperfect information is found to contain considerable explanatory power for business fluctuations signal extraction seems to provide a conceptually satisfactory empirically plausible and quantitatively important business cycle mechanism

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

the zero lower bound the dual mandate and unconventional dynamics abstract this paper examines monetary policy when it is constrained by the zero lower bound zlb on the nominal interest rate our analysis uses a nonlinear new keynesian model with technology and discount factor shocks specifically we investigate why technology shocks may have unconventional effects at the zlb what factors affect the likelihood of hitting the zlb and the implications of alternative monetary policy rules we initially focus on a new keynesian model without capital model 1 and then study that model with capital model 2 the advantage of including capital is that it introduces another mechanism for intertemporal substitution that strengthens the expectational effects of the zlb four main findings emerge 1 in model 1 the choice of output target in the taylor rule may reverse the effects of technology shocks when the zlb binds 2 when the central bank targets steady state output in model 2 a positive technology shock at the zlb leads to more pronounced unconventional dynamics than in model 1 3 the presence of capital changes the qualitative effects of demand shocks and alters the impact of a monetary policy rule that emphasizes output stability and 4 in model 1 the constrained linear solution is a decent approximation of the nonlinear solution but meaningful differences exist between the solutions in model 2

historical monetary policy analysis and the taylor rule this study examines the usefulness of the taylor rule framework as an organizing device for describing the policy debate and evolution of monetary policy in the united states monetary policy during the 1920s and since the 1951 treasury federal reserve accord can be broadly interpreted in terms of this framework with rather surprising consistency in broad terms during these periods policy has been generally formulated in a forward looking manner with price stability and economic stability serving as implicit or explicit guides as early as the 1920s measures of real economic activity relative to normal or potential supply appear to have influenced policy analysis and deliberations confidence in such measures as guides for activist monetary policy proved counterproductive at times resulting in excessive activism such as during the great inflation and at the brink of the great depression policy during the past two decades is broadly consistent with natural growth targeting variants of the taylor rule that exhibit less activism

the impact of milton friedman on modern monetary economics setting the record straight on paul krugman s who was milton friedman abstract paul krugman s essay who was milton friedman seriously mischaracterizes friedman s economics and his legacy in this paper we provide a rejoinder to krugman on these issues in the course of setting the record straight we provide a self contained guide to milton friedman s impact on modern monetary economics and on today s central banks we also refute the conclusions that krugman draws about monetary policy from the experiences of the united states in the 1930s and of japan in the 1990s

estimating the financial crisis impact on potential output abstract i use a multivariate blanchard quah decomposition to investigate the financial crisis impact on potential output in the euro area the us japan and the uk i detect an impact for all countries which is especially severe for the uk

endogenous monetary policy with unobserved potential output this paper characterizes monetary policy when policymakers are uncertain about the extent to which fluctuations in output and inflation are due to changes in potential output or to cyclical demand and cost shocks our results suggest an explanation for the inflation of the 1970s and the price stability of the 1990s it is shown that 1 policy is likely to be excessively loose for some time when there is a large decrease in potential output in comparison to a full information benchmark 2 retrospective policy errors and errors in forecasting potential output and the output gap are generally serially correlated 3 the increase in the fed s conservativeness between the 1970s and the 1990s implies that the information problem had greater consequences in the former period

performance of monetary policy with internal central bank forecasting abstract recent models of monetary policy have analyzed the desirability of different optimal and ad hoc interest rules under the restrictive assumption that forecasts of the private sector and the central bank are homogeneous this paper studies the implications of heterogeneity in forecasting by the central bank and private agents for the performance of interest rules in a framework of econometric learning

the demand for ldc exports of manufactures estimates from hong kong exports of manufactures from developing countries are generally believed to be sensitive to changes in the level of income in the developed countries their major market this belief is grounded on both casual observation especially from the experience of recent recessions and on extensive econometric evidence of low price elasticities and high income elasticities of demand for ldc exports in developed countries this paper argues that both casual observation and previous econometric evidence are misleading the aim of the paper is to show the order of magnitude of the bias contained in previous econometric estimates of price and income elasticities of demand for ldc exports of manufactures due to neglect of supply side influences previous econometric work has neglected the supply side of ldc exports for the simple reason that it is difficult to model it is difficult to model properly the supply of aggregate ldc exports since the determinants of export supply differ from country to country even for a single country modelling export supply is complicated since in addition to foreign demand and domestic supply exports are determined in part by domestic demand for exportables furthermore in most ldcs the incentive to export is strongly influenced by complex and continually changing industrial and trade policy measures there is one major exception hong kong one of the developing world s largest and most successful exporters of manufactured goods the manufacturing sector in hong kong is almost completely specialised exporting 95 of output consequently domestic demand plays no part in determining the volume of exports furthermore factor markets and the manufacturing sector are almost completely free from government intervention the main exception being the textile export restraints imposed at the insistence of importing countries the voluntary restraint agreements vras to which hong kong is subject no doubt affect the composition of exports but not necessarily the volume of aggregate exports if resources in the restrained sectors can easily be redeployed elsewhere in the economy judging from past export growth rates the vras do not appear to have had a significant effect on aggregate export growth in hong kong the results reported below also suggest that hong kong has effectively circumvented the trade barriers it faces the hong kong manufacturing sector in many ways resembles a firm in the

monetary policy rules macroeconomic stability and inflation a view from the trenches i estimate a forward looking monetary policy reaction function for the federal reserve for the periods before and after paul volcker s appointment as chairman in 1979 using information that was available to the fomc in real time from 1966 to 1995 the results suggest broad similarities in policy and point to a forward looking approach to policy consistent with a strong reaction to inflation forecasts during both periods this contradicts the hypothesis based on analysis with ex post constructed data that the instability of the great inflation was the result of weak fomc policy responses to expected inflation a difference is that prior to volcker s appointment policy was too activist in reacting to perceived output gaps that retrospectively proved overambitious drawing on contemporaneous accounts of fomc policy i discuss the implications of the findings for alternative explanations of the great inflation and the improvement in macroeconomic stability since then

testing theories of consumption behavior using information on aggregate shocks income seasonality and rainfall in rural india we develop an integrated framework for testing theories of consumption behavior by examining how agricultural households in rural india respond to anticipated and unanticipated seasonal income fluctuations using information on village level rainfall surprises we estimate idiosyncratic unanticipated income shocks by allowing weather risk to impact households differently depending on observable characteristics in applying our methodology to unique panel data on consumption debt and intrahousehold gift exchanges we address a number of shortcomings in previous tests of theories of consumption behavior yet we find no evidence against the hypothesis that households smooth idiosyncratic fluctuations in their income our approach also uncovers several interesting features of rural credit and insurance markets

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

introducing the bank of canada staff economic projections database we present a new publicly available database of real time data and forecasts from the bank of canada s staff economic projections which will be updated on an annual basis we describe the data construct its variables coverage and frequency we then provide a forecast evaluation for gross domestic product gdp growth consumer price index cpi inflation and the policy rate since 1982 we compare the staff s forecasts with those from commonly used time series models estimated with the real time data and with forecasts from other professional forecasters and provide standard bias tests finally we study changes in predictability of the canadian economy following the announcement of the inflation targeting regime in 1991 our data set is unprecedented outside the usa and our evidence is particularly interesting as it covers over 30 years of staff forecasts two severe recessions and different monetary policy regimes

demand and supply factors in the determination of nie exports a reply in their comment on muscatelli srinivasan and vines msv i992 athukorala and riedel challenge our conclusions regarding the estimated longrun elasticities of export demand for hong kong and our suggestion that estimating a system of export demand and supply could provide a solution to the normalisation problem unfortunately by focusing only on a subset of the issues raised by msv athukorala and riedel tend to ignore some of the key econometric evidence against their preferred small country assumption and their chosen normalisation price dependent export demand there are three key pieces of evidence which tend to point against the small country assumption first let us turn to the normalisation issue as athukorala and riedel note least squares methods such as the phillips hansen procedure will not yield estimates of cointegrating vectors which are independent of normalisation and that is why msv point out that the phillips hansen procedure may only alleviate not solve the normalisation problem ideally when estimating a simultaneous cointegrated model scm one should attempt to test and impose identifying restrictions on the h matrix in a johansen type multi variate var framework

shifts in us federal reserve goals and tactics for monetary policy a role for penitence during the fi rst period starting in the mid 1920s the federal reserve offi cial during the fi rst period starting in the mid 1920s the federal reserve offi cial policy was to support high quality bank lending but not speculative lending this policy was to support high quality bank lending but not speculative lending this goal was set aside once in 1927 in an episode that many observers then blamed for goal was set aside once in 1927 in an episode that many observers then blamed for the economic collapse that followed the fi nancial crash of 1929 the fed was then the economic collapse that followed the fi nancial crash of 1929 the fed was then reluctant to increase the funds available to banks through the early 1930s even as reluctant to increase the funds available to banks through the early 1930s even as the great depression ravaged the economy the fed s concern with the volume and the great depression ravaged the economy the fed s concern with the volume and quality of lending in the setting of monetary policy did eventually wither however quality of lending in the setting of monetary policy did eventually wither however this only seems to have happened after the publication of friedman and schwartz this only seems to have happened after the publication of friedman and schwartz 1963 a revisionist history of the great depression that blamed its depth on the 1963 a revisionist history of the great depression that blamed its depth on the fed s inappropriate focus on productive lending fed s inappropriate focus on productive lending in the second period after the experience of post world war ii infl ation the in the second period after the experience of post world war ii infl ation the federal reserve in the 1950s was highly concerned with infl ation and was willing to federal reserve in the 1950s was highly concerned with infl ation and was willing to raise interest rates and bring on recessions to nip even modest infl ation rates in the raise interest rates and bring on recessions to nip even modest infl ation rates in the bud this brought withering criticism for the federal reserve on the grounds that bud this brought withering criticism for the federal reserve on the grounds that the recessions of 1957 and 1960 had been unnecessary by the mid 1960s some fed the recessions of 1957 and 1960 had been unnecessary by the mid 1960s some fed offi cials seem to have developed an aversion to creating recessions as a method of offi cials seem to have developed an aversion to creating recessions as a method of

inflation forecast targeting implementing and monitoring inflation targets abstract inflation targeting is shown to imply inflation forecast targeting the central bank s inflation forecast becomes an explicit intermediate target inflation forecast targeting simplifies both implementation and monitoring of monetary policy the weight on output stabilization determines how quickly the inflation forecast is adjusted towards the inflation target money growth or exchange rate targeting is generally inferior than inflation targeting and leads to higher inflation variability commitment to target rules may be better than commitment to instrument rules

drift and breaks in labor productivity abstract we use endogenous break tests and the stock watson tvp mub methodology to investigate changes in the equilibrium rate of growth of labor productivity in the u s the eurozone the u k australia and japan since wwii results for the u s well capture the conventional wisdom of a golden era of high productivity growth the 1950s and 1960s a marked deceleration starting from the beginning of the 1970s and a strong growth resurgence starting from mid 1990s results for the eurozone point towards a deceleration since the early 1980s with the equilibrium rate of growth of output per hour falling to 0 9 in 2004 4

central bank misperceptions and the role of money in interest rate rules research with keynesian style models has emphasized the importance of the output gap for policies aimed at controlling inflation while declaring monetary aggregates largely irrelevant critics however have argued that these models need to be modified to account for observed money growth and inflation trends and that monetary trends may serve as a useful cross check for monetary policy we identify an important source of monetary trends in form of persistent central bank misperceptions regarding potential output simulations with historical output gap estimates indicate that such misperceptions may induce persistent errors in monetary policy and sustained trends in money growth and inflation if interest rate prescriptions derived from keynesian style models are augmented with a cross check against money based estimates of trend inflation inflation control is improved substantially

time varying equilibrium real rates and monetary policy analysis abstract we show how a positive correlation between the equilibrium real interest rate err and trend growth matters for two widely debated issues in monetary policy first a simple taylor rule is more robust to uncertainty about the trend growth rate than suggested by some analyses of the increase in u s inflation during the 1970s because the policy mistake made when measuring the change in trend growth gets offset by the accompanying mistake in measuring the change in the err second ignoring this correlation when estimating policy rules results in coefficients that exaggerate both the degree of interest rate smoothing and the strength of the monetary authority s response to inflation

the quest for prosperity without inflation abstract in recent years activist monetary policy rules responding to inflation and the level of economic activity have been advanced as a means of achieving effective output stabilization without inflation advocates of such policies suggest that their flexibility may yield substantial stabilization benefits while avoiding the excesses of overzealous discretionary fine tuning such as is thought to characterize the experience of the 1960s and 1970s in this study i present evidence suggesting that these conclusions are misguided using an estimated model i show that when informational limitations are properly accounted for activist policies would not have averted the great inflation but instead would have resulted in worse macroeconomic performance than the actual historical experience the problem can be attributed in large part to the counterproductive reliance of these policies on the output gap the analysis suggests that the dismal economic outcomes of the great inflation may have resulted from an unfortunate pursuit of activist policies in the face of bad measurement specifically overoptimistic assessments of the output gap associated with the productivity slowdown of the late 1960s and early 1970s

structural shifts in the manufacturing export performance of oecd economies summary this paper identifies structural shifts in manufacturing export performance of the major oecd economies the particular emphasis of this study is to see whether the longer run responses of a country s exports to the growth in world demand have undergone trend changes the econometric work focuses on the time variation in income elasticities from an export demand model over the period 1963 89 it thus covers a period in which there was a substantial slow down in world economic growth and in which the manufacturing sectors in advanced economies underwent substantial restructuring in the wake of the two oil price shocks and the competitive challenges of japan and the nics the exercise attempted to evaluate the relative successes and failures of the different oecd economies to maintain or improve their positions in the higher quality income elastic segments of world trade evidence was found for trend improvements in the income elasticity for uk exports from the early 1980s onwards and a trend decline for that of the us over the same period the effects of non tariff protection against japanese exports also showed up in our results and an attempt was made to separately identify its effects

indicator variables for optimal policy the optimal weights on indicators in models with partial information about the state of the economy and forward looking variables are derived and interpreted both for equilibria under discretion and under commitment an example of optimal monetary policy with a partially observable potential output and a forward looking indicator is examined the optimal response to the optimal estimate of potential output displays certainty equivalence whereas the optimal response to the imperfect observation of output depends on the noise in this observation

monetary policy rules based on real time data this paper examines the magnitude of informational problems associated with the implementation and interpretation of simple monetary policy rules using taylor s rule as an example i demonstrate that real time policy recommendations differ considerably from those obtained with ex post revised data further estimated policy reaction functions based on ex post revised data provide misleading descriptions of historical policy and obscure the behavior suggested by information available to the federal reserve in real time these results indicate that reliance on the information actually available to policy makers in real time is essential for the analysis of monetary policy rules

how the world achieved consensus on monetary policy the worldwide progress in monetary policy is a great achievement and especially considering the situation 30 years ago a remarkable success story i describe how the world achieved a working consensus on the core principles of monetary policy by the late 1990s i survey the muddled state of affairs in the 1970s and then ask what happened in federal reserve policy to produce an understanding of the practical principles of monetary policy how did formal institutional support for targeting low inflation abroad follow from an international acceptance of these ideas and how did a consensus theoretical model develop in academia i explain how the modern theoretical consensus known alternatively as the new neoclassical synthesis or the new keynesian model of monetary policy reinforces key advances the priority for price stability the targeting of core rather than headline inflation the importance of credibility for low inflation and preemptive interest rate policy supported by transparent objectives and procedures of course a working consensus does not constitute complete agreement accordingly the conclusion identifies important monetary policy issues that remain to be explored

does the federal reserve care about the rest of the world many economists are accustomed to thinking about federal reserve policy any economists are accustomed to thinking about federal reserve policy in terms of the institution s dual mandate which refers to price stability in terms of the institution s dual mandate which refers to price stability and high employment and in which the exchange rate and other interand high employment and in which the exchange rate and other international variables matter only insofar as they infl uence infl ation and the output national variables matter only insofar as they infl uence infl ation and the output gap which is to say not very much gap which is to say not very much in fact this conventional view is heavily shaped by the distinctive and pecuin fact this conventional view is heavily shaped by the distinctive and peculiar circumstances of the last three decades when the infl uence of international liar circumstances of the last three decades when the infl uence of international considerations on fed policy has been limited in this paper i will discuss how the considerations on fed policy has been limited in this paper i will discuss how the federal reserve paid signifi cant attention to international considerations in its fi rst federal reserve paid signifi cant attention to international considerations in its fi rst two decades followed by relative inattention to such factors in the two plus decades two decades followed by relative inattention to such factors in the two plus decades that followed then back to renewed attention to international aspects of monetary that followed then back to renewed attention to international aspects of monetary policy in the 1960s before the recent period of benign neglect of the international policy in the 1960s before the recent period of benign neglect of the international dimension this longer perspective is a reminder that just because the fed has not dimension this longer perspective is a reminder that just because the fed has not attached priority to international aspects of monetary policy in the recent past we attached priority to international aspects of monetary policy in the recent past we have no guarantee that it will not do so in the future indeed i will argue in the have no guarantee that it will not do so in the future indeed i will argue in the conclusion that in the next few decades international aspects are likely to play a conclusion that in the next few decades international aspects are likely to play a larger role in federal reserve policy making larger role in federal reserve policy making 1

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

on consequences and criticisms of monetary targeting the purpose of this paper is to review and evaluate the most important existing criticisms of policy strategies that feature adherence to money stock targets four main categories of criticism and counterargumerits are analyzed the first of these involves the claim that accurate money stock control is infeasible while the second contends that such control can only be obtained along with extreme volatility of interest rates the third emphasizes difficulties resulting from technical change and deregulation and the fourth concerns strategic issues of rules vs discretion activist vs non activist policy and the logical function of intermediate targets this abstract was borrowed from another version of this item

desirability of nominal gdp targeting under adaptive learning nominal gdp targeting has been advocated by a number of authors since it produces relative stability of inflation and output however all of the papers assume rational expectations on the part of private agents in this paper i provide an analysis of this assumption i use stability under recursive learning as a criterion for evaluating nominal gdp targeting in the context of a model with explicit micro foundations which is currently the workhorse for the analysis of monetary policy

the economic case for international labour standards this paper explores the economic case for international labour standards granting workers rights of free association and collective bargaining confers both static and dynamic economic efficiencies static efficiencies refer to one time gains from improvements in economic practice dynamic efficiencies refer to gains from improvements to the growth path resulting from a shift away from a low road development path to a high road path these efficiencies raise wages employment and output in developing countries and they can also benefit workers in developed countries labour standards are an institutional mechanism for raising the quality of growth in both developing and developed countries in this sense they are a win win institution

the u s phillips curve the case for asymmetry abstract recent statistical rejections of convexity in the phillips curve have been uninformative because researchers have employed measures of business cycle gaps that are inconsistent with the implications of convexity the paper shows that identifying convexity in the phillips curve will become even more difficult if policymakers are successful in avoiding large boom and bust cycles to the extent that convexity in the phillips curve is used as a rationale for stabilization policy our findings present an interesting conundrum because successful policymakers will further weaken the empirical evidence on which such policies are based

is the wto mystery really solved the wto s impact on bilateral trade remains puzzling due in part to previous studies failure to simultaneously address three issues inclusion of zero trade proper controls for multilateral resistance and proper membership definition addressing all fails to suggest a positive effect

real rigidities productivity improvements and investment dynamics abstract the theoretical literature on business cycles predicts a positive investment response to productivity improvements a prediction we question from theoretical and empirical perspectives we show that a short term negative response of investment to a positive technology shock is consistent with a reasonably parameterized new keynesian dynamic stochastic general equilibrium dsge model in which firm specific capital introduces an additional real rigidity and monetary policy is not fully accommodative employing bayesian techniques we provide evidence that permanent productivity improvements have short term contractionary effects on investment although this result can be obtained from both firm specific and rental capital models only in the case of the former is the average price duration in line with the microeconometric evidence

wealth varying intertemporal elasticities of substitution evidence from panel and aggregate data abstract this paper constructs and estimates a model of consumer preferences in which the intertemporal elasticity of substitution ies of consumption expenditure rises with the level of wealth the purpose of this paper is to measure the effect that systematic variation in the ies of poor and rich consumers has on the ies of aggregate consumption expenditure we find economically significant differences in the ies of poor and rich consumers in indian panel data on the consumption of individual households we also find economically significant differences in the ies measured in aggregate time series data for the u s and india

a new comparative approach to macroeconomic modeling and policy analysis in the aftermath of the global financial crisis the state of m acroeconomic modeling and the use of macroeconomic models in policy analysis has come under heavy criticism macroeconomists in academia and policy institutions are blamed for relying too much on a particular class of macroeconomic models that did not sufficiently this paper propose s a comparative approach to macroeconomic policy analysis that is open to competing modeling paradigms macroeconomic model comparison projects have helped produce some very influenti al insights such as the taylor rule however they have been infrequent and costly because they require the input of many teams of researchers and multiple meetings to obtain a limited set of comparative findings this paper provides a new comparative approach to model based research and policy analysis that enables individual researchers to conduct model comparisons easily frequently at low cost and on a large scale using this approach a model archive is built that incl udes many well known empirically estimated models that may be used for quantitative analysis of monetary and fiscal stabilization policies a computational platform is created that allows straightforward comparisons of models implications its application is illustrated by compa ring different monetary and fiscal policies across selected models researchers can easily include new models in the data base and compare the effects of novel extensions to established benchmarks thereby fostering a comparative instead of insular approach to model development

the narrow moving band the dutch disease and the competitive consequences of mrs thatcher notes on trade in the presence of dynamic scale economies abstract this paper presents a model of trade in which comparative advantage instead of being determined by underlying attributes of countries evolves over time through learning by doing in this model arbitrary patterns of specialization once established tend to become entrenched over time the model sheds light on three widely held views that do not make sense in more conventional models first is the view that temporary protection of selected sectors can permanently alter the pattern of comparative advantage in the protecting country s favor second is the view that seemingly favorable developments such as the discovery of exportable natural resources may lead to a permanent loss of other sectors and reduce welfare in the long run third is the possibility that a temporary overvaluation of a currency due to tight money can lead to a permanent loss of competitiveness in some sectors

escaping volatile inflation why has inflation been so stable in developed economies since the early 1990s in this paper we answer that the united states and other countries may have escaped from a volatile inflation equilibrium our argument builds on the story proposed by tom sargent in the conquest of american inflation where the fall in inflation in the 1980s was attributed to changing government beliefs to explain the escape in inflation volatility we unwind one of sargent s simplifications and allow the government to react to some of the shocks in the economy in this case when government beliefs turned against the phillips curve in the 1980s they not only led to an escape from high inflation but also stopped government using changes in inflation to offset shocks inflation and inflation volatility therefore escaped in tandem our analysis also sheds some light on why the escape in inflation occurred at the time it did

rate of time preference intertemporal elasticity of substitution and level of wealth the rate of time preference rtp and the intertemporal elasticity of substitution ies are two important factors shaping intertemporal consumption decisions models in which the rtp and or the ies differ systematically between rich and poor households have different empirical and policy implications for economic development growth and the distribution of income and consumption from those of standard models in which these parameters are constant across households in this chapter we estimate a model in which both rtp and ies are allowed to differ across rich and poor households using household level panel data from india our empirical results are consistent with the view that the rtp is constant across poor and rich households but the ies is larger for the rich than it is for the poor

indexing the income tax code monetary fiscal interaction and the great moderation abstract this paper considers the consequences of automatically indexing the us federal income tax code to inflation indexation implemented during the 1981 federal tax overhaul and active monetary policy constitute necessary conditions for a unique rational expectations equilibrium in standard new keynesian models with a generalized progressive labor income tax additionally fixing the monetary regime shows that indexation reduces overall volatility in the model as well as the contribution of supply side disturbances together these results support a fiscal extension to the good policy hypothesis of the great moderation and encourage further indexation of the united states tax code

the information content of capacity utilization for detrending total factor productivity abstract in the production function approach an accurate output gap assessment requires a careful evaluation of the total factor productivity tfp cycle we build a common cycle model that links tfp to capacity utilization and we show that in almost all of the pre enlargement eu countries using information about capacity utilization reduces both the total estimation error and the revisions in real time estimates of the concurrent tfp cycle compared to a univariate decomposition we also argue that relaxing the constant drift hypothesis in favour of a non linear specification helps to offset a general tendency to underestimate the tfp cycle in the last decade

inflation targeting a new framework for monetary policy he world s central bankers and their staffs meet regularly in venues from basle to washington to share ideas and discuss common problems perhaps these frequent meetings help explain why changes in the tactics and strategy of monetary policymaking such as the adoption of money growth targets in the 1970s the intensification of efforts to reduce inflation in the 1980s and the recent push for increased institutional independence for central banks tend to occur in many countries more or less simultaneously whatever their source major changes in the theory and practice of central banking are of great importance for both individual countries and the international economy in this article we discuss a new strategy for monetary policy known as inflation targeting which has sparked much interest and debate among central bankers and monetary economists in recent years this approach is characterized as the name suggests by the announcement of official target ranges for the inflation rate at one or more horizons and by explicit acknowledgment that low and stable inflation is the overriding goal of monetary policy other important features of inflation targeting include increased communication with the public about the plans and objectives of the monetary policymakers and in many cases increased accountability of the central bank

indeterminacy change points and the price puzzle in an estimated dsge model abstract we extend lubik and schorfheide s 2004 testing for indeterminacy an application to u s monetary policy american economic review 94 190 217 likelihood based estimation of dynamic stochastic general equilibrium dsge models under indeterminacy to encompass a sample period the includes both determinacy and indeterminacy by implementing a change point methodology chib s 1998 estimation and comparison of multiple change point models journal of econometrics 86 221 241 by letting the data provide estimates of the dates of the determinacy regimes and allowing the estimates of structural parameters to be the same across regimes we obtain more precise estimates of the differences in characteristics such as the impulse responses across the regimes the most striking finding about the indeterminacy regime which is estimated to coincide with the great inflation of the 1970s is that it exhibits the price puzzle in that the inflation rate rises immediately and in a sustained manner following a positive interest rate shock thus the price puzzle might have been a genuine phenomenon under indeterminacy rather than a false finding to be excised through specification search and parameter restrictions

international evidence on time variation in trend labor productivity growth this paper provides international evidence on time variation in trend productivity growth based on the dataset for hours worked constructed by ohanian raffo 2012 applying both the endogenous break tests of bai perron 1998 2003 and the stock watson 1996 1998 tvp mub methodology substantial evidence of time variation in trend productivity growth is detected for most countries for either japan or countries belonging to the eurozone evidence points towards a significant growth decline over the last several decades weaker evidence is reported for the united states for which the 1990 s productivity acceleration is estimated to have been overall mild and of a temporary nature

intra nie competition in exports of manufactures this paper provides empirical evidence on the extent to which the asian newly industrialised economies nies compete in world export markets our results support existing studies which emphasise the importance of allowing for intra ldc competition in modelling an individual developing country s exports whilst the asian nies are regarded as a model for other developing countries to emulate one has to consider whether such an expansion in export supply would be at the expense of oecd economies or whether it will lead to a deterioration in the terms of trade of the developing countries as a group

income and price elasticities for exports of developing countries income and price elasticities for non oil exports of non opec developing countries play an imp ortant role in the development of policy responses to the debt crisis these elasticities are estimated for the major standard internation al trade classification commodity groups based on two stage least sq uares and quarterly data for 1973 to 1984 the income elasticity for non oil exports ranges between 1 4 and 1 9 the analysis also tests t he properties of the error term the dynamic specification and para metric stability the sensitivity of the results is assessed using sh iller s lags and band spectrum estimation copyright 1988 by mit press

the robustness and efficiency of monetary policy rules as guidelines for interest rate setting by the european central bank abstract this paper examines the implications of recent research on monetary policy rules for practical monetary policy making with special emphasis on strategies for setting interest rates by the european central bank ecb the paper draws on recent research and new simulations of a large open economy model to assess the efficiency of a simple benchmark rule in comparison with other proposed rules further it stresses new results on the robustness of monetary policy rules in which each rule that is optimal or good according to one model or researcher is tested for robustness by other researchers using different models because of the large increase in the number of economists focussing on econometric evaluation of monetary policy rules for the interest rate instrument and because of the parallel increase in the variety of models being developed for this purpose much more evidence is becoming available on the robustness of simple monetary policy rules for the interest rate than ever before

signalling effects of monetary policy we develop a dynamic general equilibrium model in which the policy rate signals the central bank s view about macroeconomic developments to price setters the model is estimated with likelihood methods on a u s data set that includes the survey of professional forecasters as a measure of price setters inflation expectations this model improves upon existing perfect information models in explaining why in the data inflation expectations respond with delays to monetary impulses and remain disanchored for years in the 1970s u s monetary policy is found to signal persistent inflationary shocks explaining why inflation and inflation expectations were so persistently heightened the signalling effects of monetary policy also explain why inflation expectations adjusted more sluggishly than inflation after the robust monetary tightening of the 1980s

an analysis of the disaggregated manufacturing exports of the asian nies to eec usa and japan this paper examines the export performance of the four asian newly industrialized economics nies by modelling their bilateral export flows to three main oecd blocks the usa japan and the european community our estimated export demand models reveal interesting asymmetries between these three areas of destination which do not emerge from previous aggregate empirical studies of nie export performance

real wage rigidity and the taylor principle abstract this paper investigates conditions for equilibrium determinacy in the basic new keynesian model with real wage rigidity the determinacy region is increased under forward looking rules and the taylor principle continues to ensure equilibrium uniqueness under current looking rules

choosing the federal reserve chair lessons from history stable noninflationary growth has been the goal of monetary policymakers since the inception of the modern federal reserve in the mid 1930s policymakers however have come closer to achieving this goal in some eras than in others under chairmen william mcchesney martin jr in the 1950s and early 1960s and alan greenspan in the late 1980s and beyond the federal reserve presided over decades of low inflation and mild real fluctuations under paul volcker in the 1980s the federal reserve oversaw a significant recession but one that returned the american economy to near price stability and steady growth in contrast under marriner eccles in the late 1930s the federal reserve triggered a recession that was second in severity only to the great depression and that resulted in severe deflation and under arthur burns and g william miller in the 1970s the u s economy experienced high and rising inflation and painfully variable real growth an obvious question is why monetary policy has been so much more successful under some federal reserve chairmen than others this question has taken on new urgency because current chairman alan greenspan will need to be replaced in the near future it is crucial to understand what has determined policy success in the past and to identify factors that help predict success only by learning the lessons of history will we be able to choose a new federal reserve chair who is likely to replicate our policy triumphs and avoid our policy failures this paper demonstrates that the key determinants of policy success have been policymakers views about how the economy works and what monetary policy can

the future of monetary aggregates in monetary policy analysis this paper considers the role of monetary aggregates in modern macroeconomic models of the new keynesian type the focus is on possible developments of these models that are suggested by the monetarist literature and that in addition seem justified empirically both the relation between money and inflation and between money and aggregate demand are considered regarding the first relation it is argued that both the mean and the dynamics of inflation in present day models are governed by money growth this relationship arises from a conventional aggregate demand channel claims that an emphasis on the link between monetary aggregates and inflation requires a direct channel connecting money and inflation are wide of the mark the relevance of money for aggregate demand in turn lies not via real balance effects or any other justification for money in the is equation but on money s ability to serve as a proxy for the various substitution effects of monetary policy that exist when many asset prices matter for aggregate demand this role for monetary aggregates which is supported by empirical evidence enhances the value of money to monetary policy

rethinking monetary policy after the crisis abstract this lecture examines how the recent global financial crisis changes our thinking about how monetary policy should be conducted it starts with a discussion of the science and practice of monetary policy before the crisis and then uses the lessons from the crisis to argue how the practice of monetary policy should be rethought along six dimensions flexible inflation targeting response to asset price bubbles dichotomy between monetary policy and financial stability policy risk management and gradualism fiscal dominance and forward guidance

demand and supply factors in the determination of nie exports a simultaneous error correction model for hong kong this paper considers the issue of whether a small developing economy such as hong kong faces a perfectly elastic demand for its exports of manufactured goods we construct a simultaneous demand and supply system which is estimated using full information maximum likelihood methods and which allows us to clearly identify demand and supply factors in determining export volumes and prices our empirical findings differ from previous studies conducted with this data set in that they suggest that even a small dynamic newly industrialized economy such as hong kong may not face infinitely elastic demand for its manufactured goods we also advance some reasons to explain why the small country assumption may not be applicable in the case of most industrialized economies

does the fed act gradually a var analysis abstract the tendency for changes in the federal funds rate to be implemented gradually has been considered evidence of an interest rate smoothing objective for the federal reserve this paper investigates whether gradual funds rate movements can be explained by the dynamic structure of the economy and the uncertainty surrounding that structure without recourse to including an ad hoc interest rate smoothing argument in the fed s objective function in the absence of parameter uncertainty the optimal policy involves more aggressive movements in the funds rate than observed parameter uncertainty however limits the responsiveness of the interest rate as a result the optimal policy under parameter uncertainty can account for a considerable portion of the gradualism observed

in old chicago simons friedman and the development of monetary policy rules this paper examines the different policy rules proposed by henry simons who beginning in the mid 1930s advocated a price level stabilization rule and by milton friedman who beginning in the late 1950s advocated a rule that targeted a constant growth rate of the money supply although both rules shared the objective of eliminating the policy uncertainty emanating from discretion they differed because of the different views of simons and friedman about the stability of secular relationships simons rule relates to modern rules that emphasize the pursuit of price stability as representing optimal monetary policy

the case for forecast targeting as a monetary policy strategy at central banks around the world forecasts have come to play an increasingly important role both in policy deliberations and in communications with the public the most striking examples are the bank of england sweden s riksbank norway s norges bank and the reserve bank of new zealand all of which conduct policy on the basis of a procedure sometimes referred to as inflation forecast targeting svensson 1997 1999 under this approach the central bank constructs quantitative projections of the economy s expected future evolution based on the way in which it intends to control short term interest rates and public discussion of those projections is a critical part of the way in which the bank justifies the conduct of policy to the public what accounts for the appeal of a forecast targeting approach and should it be adopted more widely or more explicitly i begin by reviewing the long running debate between the proponents of monetary rules intended to ensure confidence in the value of money over time and the proponents of discretionary monetary policy aimed at stabilizing the real economy i will argue that inflation forecast targeting represents a powerful synthesis of the two approaches in particular it is an improvement both over simpler rules such as targeting a monetary aggregate and over weaker versions of inflation targeting i shall also argue that a much more extensive communication policy is crucial to escaping from the limitations of the traditional alternatives of rigid rules or rudderless discretion i will then explore some common questions that arise about inflation forecast targeting should only the inflation forecast matter and if not in what way should forecasts of other economic variables affect policy decisions what assumptions about the course of future policy should be used in constructing the quantitative projections that are presented to the public finally given that economic forecasts

can the east asian model of development be generalized abstract export led growth has become increasingly popular among analysts and some governments as a development strategy besides contrasting its virtues to the distortions of the import substitution model popular through the 1960s advocates of the model frequently illustrate its merits by pointing to the remarkable success of its most prominent practitioners the east asian gang of four hong kong korea singapore and taiwan this study explores a possible limitation of the model known as the fallacy of composition while the model may work well if pursued by a limited number of countries it may break down if a large majority of developing countries seeks to pursue it at the same time because the resulting outpouring of manufactured exports might be more than western markets could absorb protectionist response might be the result of attempts to generalize the east asian export model of growth

import competition from developed and developing countries separate demand equations for imports from less developed countries ldcs and imports from developed countries dcs were estimated for each of eleven representative product groups imports were found to compete quite readily with domestically produced goods with plausible own price and cross price elasticities whereas the quantity of each type of import was found to be quite responsive to changes in the price of us home goods each appears to be less sensitive to the price of the alternative import an explanation that is consistent with this observation and that finds support from detailed industry information is that dcs and ldcs supply goods that are at different stages in the product or technology cycle whereas us producers compete in all submarkets this suggests that trade creation rather than trade diversion provides the predominant inroad for ldcs into the us market 25 references 3 tables

inflation risk premia and the expectations hypothesis abstract we study the properties of the nominal and real risk premia of the term structure of interest rates we develop and solve the bond pricing implications of a structural monetary version of a real business cycle model with taxes and endogenous monetary policy we show the relation of this model with the class of essentially affine models that incorporate an endogenous state dependent market price of risk we characterize and estimate the inflation risk premium and find that over the last 40 years the ten year inflation risk premium has been has averaged 70 basis points it is time varying ranging from 20 to 140 basis points over the business cycle and its term structure is sharply upward sloping the inflation risk premium explains 23 42 of the time variation in the five ten year forward risk premium and it plays an important role in help explain deviations from the expectations hypothesis of interest rates

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

data revisions and the identification of monetary policy shocks abstract monetary policy research using time series methods has been criticized for using more information than the federal reserve had available to quantify the role of this criticism we estimate vars with real time data while accounting for the latent nature of many economic variables such as output our estimated monetary policy shocks are closely correlated with typically estimated measures the impulse response functions are broadly similar across estimation methods our evidence suggests that the use of revised data in var analyses of monetary policy shocks may not be a serious limitation for recursively identified systems but presents more challenges for simultaneous systems

are non fundamental equilibria learnable in models of monetary policy abstract recent models of monetary policy can have indeterminacy of equilibria which is often viewed as a difficulty of these models we consider the significance of indeterminacy using the learning approach to expectations formation we employ expectational stability as a selection criterion for different equilibria and derive the expectational stability and instability conditions for forward looking multivariate models both without and with lags the results are applied to several monetary policies

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

robust monetary policy with imperfect knowledge we examine the performance and robustness properties of monetary policy rules in an estimated macroeconomic model in which the economy undergoes structural change and where private agents and the central bank possess imperfect knowledge about the true structure of the economy private agents rely on an adaptive learning technology to form expectations and update their beliefs based on incoming data policymakers follow an interest rate rule aiming to maintain price stability and to minimize uctuations of unemployment around its natural rate but are uncertain about the economy s natural rates of interest and unemployment we show that in this environment the scope for economic stabilization is signiflcantly reduced relative to an economy under rational expectations with perfect knowledge furthermore policies that would be optimal under perfect knowledge can perform very poorly when knowledge is imperfect e cient policies that take account of private learning and misperceptions of natural rates call for more aggressive responses to in ation that would be optimal under perfect knowledge we show that such policies not only improve performance in our baseline model but are also quite robust to potential misspeciflcation of private sector learning and the magnitude of variation in natural rates

perhaps the 1970s fomc did what it said it did briefing forecasts prepared for the federal open market committee fomc are used to estimate changes in the design of us monetary policy and in the implied policy target for inflation from 1970 through 1997 both estimated policy rate responses and fomc transcripts are consistent with intermediate targeting of monetary aggregates throughout the great inflation of the 1970s the unpublished fomc targets for m1 growth are tabulated empirical results support an effective inflation target of roughly 7 in the 1970s and 3 thereafter a notable difference in the 1970s monetary policies of the us and germany is the absence of explicit public objectives for us long run inflation

consumption smoothing migration and marriage evidence from rural india a significant proportion of migration in low income countries particularly in rural areas is composed of moves by women for the purpose of marriage we seek to explain these mobility patterns by examining marital arrangements among indian households in particular we hypothesize that the marriage of daughters to locationally distant dispersed yet kinship related households is a manifestation of implicit interhousehold contractual arrangements aimed at mitigating income risks and facilitating consumption smoothing in an environment characterized by information costs and spatially covariant risks analysis of longitudinal south indian village data lends support to the hypothesis marriage cum migration contributes significantly to a reduction in the variability of household food consumption farm households afflicted with more variable profits tend to engage in longer distance marriage cum migration the hypothesized and observed marriage cum migration patterns are in dissonance with standard models of marriage or migration that are concerned primarily with search costs and static income gains

simple monetary policymaking without the output gap several research contributions have argued that information about the output gap is essential for a good monetary policy rule however as pointed out by orphanides 2001 there is considerable real time uncertainty about the size of the output gap the paper argues that simple monetary policy rules that rely exclusively on survey based information about future and past inflation rates may be more efficient than optimized taylor rules once realtime output gap uncertainty is accounted for even when only information about historical inflation rates is available a very simple policy rule may be constructed that improves on the taylor rule
