monetary policy in an uncertain world in this article charles bean bank of england chief economist and member of the monetary policy committee reviews and assesses the three types of uncertainty which affect monetary policymakers uncertainty about the data uncertainty about the nature and persistence of shocks and uncertainty about the structure of the economy focusing on uncertainty about the structure of the economy he notes the unusual stability of inflation and output growth in the past decade or so there are a number of possible explanations including plain good luck structural changes in the economy and improved policymaking the author goes on to note that the short run trade off between inflation and activity seems to have flattened as inflation has stabilised at low levels and he attributes this in part to improved monetary policymaking he goes on to consider some of the policy implications of this change

the signaling effect of raising inflation abstract this paper argues that central bankers should temporarily raise inflation when anticipating liquidity traps to ensure the credibility of otherwise time inconsistent forward guidance policies as stable inflation in normal times either stems from central bankers desire to maintain credibility or from aversion to inflation the private sector is unable to infer the central banker s willingness to follow through on promises from observing stable inflation jeopardizing the efficiency of forward guidance policy we show that this signaling motive can justify temporary deviations of inflation from target well above 2 but also that the low inflation volatility during the great moderation was insufficient to ensure fully efficient forward guidance when needed

innovations and issues in monetary policy panel discussion martin feldstein 1 chairman alan greenspan s remarks today give us an opportunity to understand his thinking about monetary policy and about the federal reserve s actions during the past 15 years it was a period of substantial accomplishment that no doubt reflects in considerable measure the views of the chairman himself the fed s primary goal price stability has been achieved with inflation down from 4 percent at the end of the 1980 s to about 1 5 percent now the 2 percentage point difference between the interest rate on conventional treasury bonds and on inflation indexed bonds tips shows that financial markets expect inflation will remain at about 2 percent for at least the next decade

monetary policy and real wage cyclicality this article points to the potential role of monetary policy in affecting the degree of real wage cyclicality we show that the degree and direction of real wage cyclicality is determined by the interaction of i the returns to scale in production ii the nature of aggregate shocks and iii monetary policy given that production technology is fairly constant in the short run we suggest that variations in the real wage output covariance depend largely on the combination of the latter two identifying well documented monetary policy phases in six major organization for economic co operation and development oecd countries and accounting for both aggregate demand and supply shocks we provide empirical evidence to support our main theoretical claim

racial discrimination in the labor market theory and empirics we review theories of race discrimination in the labor market taste based models can generate wage and unemployment duration differentials when combined with either random or directed search even when strong prejudice is not widespread but no existing model explains the unemployment rate differential models of statistical discrimination based on differential observability of productivity across races can explain the pattern and magnitudes of wage differentials but do not address employment and unemployment at their current state of development models of statistical discrimination based on rational stereotypes have little empirical content it is plausible that models combining elements of the search models with statistical discrimination could fit the data we suggest possible avenues to be pursued and comment briefly on the implication of existing theory for public policy jel j15 j31 j64 j71

does central bank transparency impact financial markets a cross country econometric analysis blinder et al 2001 argues that more open public disclosure of central bank policies may enhance the efficiency of markets we examine this claim by studying for a set of seven industrialized countries whether selected central banks moves toward more open disclosure during the 1990s improved or worsened the predictability of the corresponding national financial markets employing methodologies analogous to campbell and schiller 1991 we find that for all countries the forecasting error has decreased for interest rates on the respective government bonds across most maturity lengths and that the expectations hypothesis has generally performed better at the short end of the yield curve our results also tentatively show that the effects are stronger for central banks that made the move to greater disclosure compared to those banks that resisted increasing the public s information set these findings are consistent with tabellini s 1987 view that central bank secrecy will hinder the smooth functioning of financial markets

outsiders at the bank of england s mpc the monetary policy committee mpc of the bank of england which was established in may 1997 consists of five internal and four external members we study the voting record and show that insiders dissent rarely and typically for higher rather than lower rates whereas outsiders dissent more often prefer lower rates and disagree with the majority when economic growth slows moreover their dissents forecast future interest rate changes we show that a model in which outsiders dislike output below potential more than output above replicates the observed voting pattern well

first impressions matter signalling as a source of policy dynamics we provide the first direct empirical support for the importance of signalling in monetary policy by testing two key predictions from a novel structural model first all policymaker types should become less tough on inflation over time and secondly types that weigh output more should have a more pronounced shift voting data from the bank of england s monetary policy committee strongly support both predictions counterfactual results indicate signalling has a substantial impact on interest rates over the business cycle and improves the committee designer s welfare implications for committee design include allowing regular member turnover and transparency regarding publishing individual votes

collective moral hazard maturity mismatch and systemic bailouts the paper elicits a mechanism by which private leverage choices exhibit strategic complementarities through the reaction of monetary policy when everyone engages in maturity transformation authorities haver little choice but facilitating refinancing in turn refusing to adopt a risky balance sheet lowers the return on equity the key ingredient is that monetary policy is non targeted the ex post benefits from a monetary bailout accrue in proportion to the number amount of leverage while the distortion costs are to a large extent fixed this insight has important consequences first banks choose to correlate their risk exposures second private borrowers may deliberately choose to increase their interest rate sensitivity following bad news about future needs for liquidity third optimal monetary policy is time inconsistent fourth macro prudential supervision is called for we characterize the optimal regulation which takes the form of a minimum liquidity requirement coupled with monitoring of the quality of liquid assets we establish the robustness of our insights when the set of

do central banks react to house prices we estimate the federal reserve s the bank of england s and the bank of japan s responses to house prices we show that generalized method of moments estimates of a taylor rule augmented with house prices are biased and dispersed we then use full information methods and estimate the policy rule together with a var for the nonpolicy variables these estimates are also biased we propose an alternative approach and estimate a dynamic stochastic general equilibrium model embedded with a monetary rule with a direct response to house prices we find that house prices played a separate role in the reaction functions of these central banks

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

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

keynesian and monetarist theories of the monetary transmission process doctrinal aspects abstract this paper investigates the doctrinal link underlying differences between keynesian and monetarist approaches regarding the transmission mechanism of monetary policy consideration of the post general theory literature reveals that a key aspect of that link concerns the velocity of circulation of money the keynesian emphasis on compartmentalizing the demand for money into active and idle components resulted in a mechanical interpretation of velocity and the associated view that money does not matter the monetarist tradition illustrates the behavioral perspective adduced to velocity via adaptive price expectations by earlier quantity theorists leading to a capital theoretic reformulation of the quantity theory in terms of a stable demand function for money

habit formation in consumption and its implications for monetary policy models this paper explores a monetary policy model with habit formation for consumers in which consumers utility depends in part on current consumption relative to past consumption the empirical tests developed in the paper show that one can reject the hypothesis of no habit formation with tremendous condence largely because the habit formation model captures the gradual hump shaped response of real spending to various shocks the paper then embeds the habit consumption specication in a monetary policy model and nds that the responses of both spending and inflation to monetary policy actions are signicantly improved by this modication jel d12 e52 e43

var analysis and the great moderation post world war ii us macroeconomic history is usually divided into two distinct subperiods the former period which extends up to the end of the volcker disinflation is characterized by a significant extent of macroeconomic turbulence with highly volatile inflation and output growth the latter period from the end of the volcker disinflation up to the present day is marked in contrast by significantly smaller volatilities for both inflation and output growth these dramatic changes in the reduced form properties of the us economy over the last several decades char acterize a phenomenon known as the great moderation see in particular chang jin kim and charles nelson 1999 margaret mcconnell and gabriel perez quiros 2000 a vast empirical literature has investigated the source s of the great moderation in an attempt to disentangle the relative contributions of two main explanations good policy and good luck based on time varying or markov switching structural var methods the good luck hypoth esis has been advocated by a number of authors including james h stock and mark w watson 2003 giorgio e primiceri 2005 christopher sims and tao zha 2006 and luca gambetti evi pappa and fabio canova 2008

stabilisation policy targets and unemployment in imperfectly competitive economies this paper argues that the rate of equilibrium unemployment depends on the objectives of the central bank in a model where the central bank uses monetary policy to stabilise the economy we show that unemployment and inflation will be lower with an inflation target than with targets for output money or nominal gdp the intuition for this is that the elasticities of demand in both the product and the labour markets are greater when there is an inflation target we show that this leads to a lower mark up of price over marginal cost and makes wages more sensitive to unemployment

an overhaul of doctrine the underpinning of uk inflation targeting this paper argues that the inflation targeting regime prevailing in the united kingdom is not the result of a change in policymaker objectives by conducting an analysis of u k policymakers that parallels romer and romer s 2004 study of federal reserve chairmen i demonstrate that policymaker objectives have been essentially unchanged over the past five decades instead the crucial underpinning of u k inflation targeting has been an overhaul of doctrine a changed view of the transmission mechanism this overhaul can be understood in terms of changes in policymakers views on the values of a few key parameters in their specifications of the economy s is and phillips curves specifically the changed views pertain to the issues of whether interest rates enter the is equation and the extent of policymaker influence on those rates whether the level of the output gap appears in the phillips curve when the gap is negative and whether a speedlimit term matters for inflation dynamics contrary to conventional wisdom changing views on the expected inflation term in the phillips curve do not play a role

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

ban the box convictions and public employment ban the box btb policies mandate deferred access to criminal history until later in the hiring process however these policies chiefly target public employers the study is the first to focus on the primary goal of btb reform by measuring the impact of btb policies on the probability of public employment for those with convictions to execute the analyses the study uses data from the national longitudinal survey of youth 1997 cohort 2005 2015 and difference in difference dd estimation the study finds that btb policies raise the probability of public employment for those with convictions by about 30 on average some scholars argue that btb policies encourage statistical discrimination against young low skilled minority males the study employs triple difference ddd estimation to test for statistical discrimination but uncovers no evidence to support the hypothesis jel j15 j71 j78 k4

affirmative action and the utilization of minority and women owned businesses in highway procurement i introduction affirmative action programs in public procurement are among the more important government programs intended to advance self employment opportunities for minorities and women in 2002 6 75 of federal procurement dollars were awarded to disadvantaged business enterprises dbes through the small business administration and preferential treatment for minority firms is a common feature of many state and local government agencies recent court decisions and state measures have reduced the scope of and in some settings eliminated affirmative action programs based on race or gender which has given renewed importance to understanding the role of affirmative action in the success of self employed minorities and women the use of affirmative action is particularly widespread in the highway procurement industry since the late 1970s and early 1980s most states have employed affirmative action to award contracts to minority owned firms and since 1982 the federal highway administration fhwa has required states use affirmative action in awarding projects using federal funds in 1998 states awarded 14 6 billion of construction and repair contracts using federal funds of which 1 9 billion was awarded to firms owned by minorities and women as blanchflower and wainright 2005 note in the intervening years states have increasingly been able to use race neutral measures to meet goals which has had an adverse effect on utilization of minority owned firms understanding the effects of affirmative action in this industry is made important by the significance of the public sector according to the 2002 census of industries 72 6 of the revenue earned by firms in the highway street and bridge construction industry was from government owned projects as a result changes in public procurement policy will have a strong effect on firms in the highway construction industry despite the importance of affirmative action in this industry our understanding of the effects of these programs is limited states generally use percentage goals for the participation of minority owned subcontractors by prime contractors past research has established the response of dbe utilization to large episodic changes in affirmative action such as the elimination by certain states or cities of affirmative action programs blanchflower and wainright 2005 however little evidence exists regarding the intensive margin of affirmative action in public procurement that is as participation goals are raised or lowered what is the response of the utilization of dbes generally and minority and women owned firms specifically higher dbe goals do not necessarily raise the utilization of firms owned by minorities and women for two reasons first the dbe goal may not be binding in which case the marginal effect of small changes to the goal would be zero second goals for the utilization of dbes are often not perfectly enforced for instance a contractor facing a requirement to subcontract a fraction of a contract to dbes can skirt this requirement by documenting a good faith effort to employ firms owned by minorities and women the goal of this paper is to provide new evidence regarding the effectiveness of affirmative action programs in highway procurement at increasing purchases from firms owned by minorities and women two sources of variation are employed to answer this question the first is variation in dbe goals across states over time and the second is variation across projects within a state i begin by examining state level data regarding affirmative action goals and dbe utilization over the entire history of the fhwa s affirmative action program i utilize changes in affirmative action goals over time within states to identify the effect of affirmative action intensity on the level of dbe purchases i find that increasing goals for the utilization of dbe goals substantially raise the utilization of minority owned business enterprises mbes

a simple empirical measure of central banks conservatism in this paper we suggest a simple empirical and model independent measure of central banks conservatism based on the taylor curve this new indicator can easily be extended in time and space whatever the underlying monetary regime of the considered countries we demonstrate that it evolves in accordance with the monetary experiences of 32 oecd member countries from 1980 and is largely equivalent to the model based measure provided by krause mendez southern economic journal 2005 we finally bring forward the interest of such an indicator for further empirical analysis dealing with the preferences of central banks

changes in uk monetary policy rules and discretion in practice abstract in october 1992 following sterling s departure from the exchange rate mechanism britain adopted a new framework for monetary policy that comprised two components first an explicit target for inflation and second institutional changes designed to give greater influence to the bank of england by increasing the transparency and openness of the process by which interest rates are set this paper analyses those changes from the perspective of the debate on rules versus discretion and argues that an appropriate design of institutional arrangements can provide incentives for central bankers to pursue the first best state contingent monetary policy

an open economy new keynesian phillips curve for the u k abstract we estimate a pricing equation or new keynesian phillips curve nkpc obtained from a structural dynamic model of price setting based on rotemberg 1982 sticky prices in the united states journal of political economy 90 6 1187 1211 and extended to capture employment adjustment costs and the openness of the united kingdom this model nests the baseline gali and gertler 1999 inflation dynamics a structural econometric analysis quarterly journal of economics 110 127 159 and sbordone 2002 prices and unit labor costs a new test of price stickiness journal of monetary economics 49 265 292 relationship between inflation and marginal cost in the limiting case of no employment adjustment costs no impact of relative prices of imported inputs on real marginal cost and a constant equilibrium markup our findings indicate that each of our modifications to the baseline nkpc model is important for u k data so that inflation in the u k is explained both by changes in employment and by changes in real import prices in general and real oil prices in particular external competitive pressures also seem to affect u k inflation via their impact on the equilibrium price markup of domestic firms

monetary policy product market competition and growth in this paper we argue that monetary easing fosters growth more in more credit constrained environments and the more so the higher the degree of product market competition indeed when competition is low large rents allow firms to stay on the market and reinvest optimally no matter how funding conditions change with aggregate conditions to test this prediction we use industrylevel and firm level data from the euro area to look at the effects on sectoral growth and firm level growth of the unexpected drop in long term government bond yields following the announcement of the outright monetary transactions program omt by the ecb we find that the monetary policy easing induced by omt contributed to raising sectoral firm level growth more in more highly leveraged sectors firms and the more so the higher the degree of product market competition in the country sector

monetary policy in the uk the authors argue that the institutional dimension of the bank of england monetary policy and the role the uk hm treasury assumes in this framework are both firmly based on the new consensus in macroeconomics ncm this is also the theoretical framework upon which the inflation targeting element of monetary policy is firmly based this paper discusses these aspects of uk monetary policy and then assesses the policy that has been pursued since 1997 with some reference made to the period between 1992 and 1997 when a version of the framework was introduced the strategy has been successful in terms of keeping uk inflation rates within the targets set by hm treasury however a number of problematic issues are highlighted and discussed

robust monetary policy with competing reference models abstract the existing literature on robust monetary policy rules has largely focused on the case in which the policymaker has a single reference model while the true economy lies within a specified neighborhood of the reference model in this paper we show that such rules may perform very poorly in the more general case in which non nested models represent competing perspectives about controversial issues such as expectations formation and inflation persistence using bayesian and minimax strategies we then consider whether any simple rule can provide robust performance across such divergent representations of the economy we find that a robust outcome is attainable only in cases where the objective function places substantial weight on stabilizing both output and inflation in contrast we are unable to find a robust policy rule when the sole policy objective is to stabilize inflation we analyze these results using a new diagnostic approach namely by quantifying the fault tolerance of each model economy with respect to deviations from optimal policy

pitfalls of forward looking monetary policy a distinctive feature of the procedures recently adopted by inflation targeting central banks is their forward looking character forecasts of the economy s future evolution conditional upon alternative policies play a central role in the banks deliberations to an extent that the procedures adopted are sometimes characterized as forecast targeting this emphasis upon the future consequences of policy is unsurprising in an approach that tries to maintain as transparent as possible a relation between the banks9 decisions and the ultimate goals of monetary policy after all current decisions can still affect the future but not the past nonetheless common descriptions of how inflation targeting is or should be practiced go too far in proposing purely forward looking procedures i shall argue instead that an optimal framework for the conduct of monetary policy must generally be history dependent in ways

communication by central bank committee members different strategies same effectiveness the paper assesses the communication strategies of the federal reserve the bank of england and the european central bank and their effectiveness we find that the effectiveness of communication is not independent from the decision making process the paper shows that the federal reserve has been pursuing a highly individualistic communication strategy amid a collegial approach to decision making while the bank of england is using a collegial communication strategy and highly individualistic decision making the european central bank ecb has chosen a collegial approach both in its communication and in its decision making assessing these strategies we find that predictability of policy decisions and the responsiveness of financial markets to communication are equally good for the federal reserve and the ecb this suggests that there may not be a single best approach to designing a central bank communication strategy

asymmetric size dependent effects of the output gap on inflation us evidence from the last half a century this article examines asymmetric size and sign dependent effects of the output gap on the us quarterly inflation rate using data from the last half a century 1959q2 2013q1 consistent with previous studies it is found that the consumer price index is cointegrated with the unit labour cost and the price of oil a short run dynamic model is then estimated in which variations in the output gap are divided into three groups large positive large negative and small medium positive negative the results provide convincing evidence that only sufficiently large positive or negative variations of the output gap can significantly influence inflation put otherwise relatively small to medium changes in the output gap exert no significant impact on inflation and if not separated they can somewhat obscure the significant effects associated with large variations of the output gap this study can lead to greater consensus on the inflation output gap nexus the findings remain robust despite the use of differen

the performance of forecast based monetary policy rules under model uncertainty we investigate the performance of forecast based monetary policy rules using five macroeconomic models that reflect a wide range of views on aggregate dynamics we identify the key characteristics of rules that are robust to model uncertainty such rules respond to the one year ahead inflation forecast and to the current output gap and incorporate a substantial degree of policy inertia in contrast rules with longer forecast horizons are less robust and are prone to generating indeterminacy in light of these results we identify a robust benchmark rule that performs very well in all five models over a wide range of policy preferences

expectation traps and discretion abstract we develop a dynamic model with optimizing private agents and a benevolent optimizing monetary authority that cannot commit to future policies we characterize the set of sustainable equilibria and discuss the implications for institutional reform we show that there are equilibria in which the monetary authority pursues inflationary policies because that is what private agents expect we call such equilibria expectation traps alternative institutional arrangements for the conduct of monetary policy which impose limited forms of commitment on the policymaker can eliminate expectation traps journal of economic literatureclassification numbers e31 e42 e50 e51 e58

do markets care who chairs the central bank this paper assesses the effects of central bank governor appointments on financial market expectations of monetary policy to measure these effects we assemble a new dataset of appointment announcements from 15 countries and conduct an event study analysis on exchange rates bond yields and stock prices our main findings are threefold first exchange rates and bond yields display a statistically significant response to the announcement of a new governor especially when the appointee s identity was not anticipated in advance second the reactions are especially pronounced for central banks lacking either independence or a clear nominal anchor third new governors are not generally perceived to lack credibility there is no tendency for announcements to be associated with jumps in inflation expectations

identifying sources of macroeconomic and exchange rate fluctuations in the uk abstract using quarterly data for the period 1985 1 2011 1 this paper uses a stylised open economy structural var model to identify the types of shocks responsible for macroeconomic fluctuations in the uk economy the stylised model implies a set of short run restrictions that allow for the identification of the shocks the importance of each shock is determined by examining forecast error variance decompositions impulse response functions and implied long run or permanent effects the results presented here imply that two shocks called the technology and is shocks are relatively more important than other shocks monetary shocks do exhibit long run monetary neutrality but clearly monetary policy is not responsible for a meaningful share of output and employment fluctuations during the sample period the estimated var and structural disturbances imply that the model accurately reflects the uk economy there is little evidence of a price puzzle or an exchange rate puzzle evidence against uncovered interest rate parity in response to an unexpected monetary policy tightening

on targeting frameworks and optimal monetary policy we show that speed limit policy a monetary policy strategy that focuses on stabilizing inflation and the change in the output gap consistently outperforms flexible inflation targeting and flexible price level targeting in empirical medium scale dsge models under discretionary policymaking in contrast to small scale new keynesian models this welfare ranking of the targeting frameworks is not overturned when inflation dynamics are mostly backward looking importantly the performance of the speed limit policy shows less sensitivity to its parameterization than other frameworks that target the inflation rate or the price level

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

the great moderation in the united kingdom we use a bayesian time varying parameters structural var with stochastic volatility for gdp deflator inflation real gdp growth a 3 month nominal rate and the rate of growth of m4 to investigate the underlying causes of the great moderation in the united kingdom our evidence points toward a dominant role played by good luck in fostering the more stable macroeconomic environment of the last two decades results from counterfactual simulations in particular show that i bringing the monetary policy committee back in time would only have had a limited impact on the great inflation episode at the cost of lower output growth ii imposing the 1970s monetary rule over the entire sample period would have made almost no difference in terms of inflation and output growth outcomes and iii the great inflation was due to a dominant extent to large demand non policy shocks and to a lesser extent especially in 1973 and 1979 to supply shocks

on the optimal monetary policy response to noisy indicators abstract we describe a behavior of a central bank when its measures of current inflation and output are subject to measurement errors in a framework of optimizing models with nominal price stickiness in our model a central bank sets the interest rate equal to its current estimate of the so called wicksellian natural rate of interest this is shown to imply that the interest rate responds to the central bank s estimates of both current inflation and output gap as advocated by taylor 1993 it is also shown that the noise contained in the indicators justifies a degree of policy cautiousness a reduced form representation of optimal policy should exhibit interest rate smoothing which is often found in the empirical literature on monetary policy reaction functions

volatility and growth credit constraints and the composition of investment abstract how does uncertainty and credit constraints affect the cyclical composition of investment and thereby volatility and growth this paper addresses this question within a model where firms engage in two types of investment a short term one and a long term one which contributes more to productivity growth because it takes longer to complete long term investment has a relatively less cyclical return but it also has a higher liquidity risk the first effect ensures that the share of long term investment to total investment is countercyclical when financial markets are perfect the second implies that this share may turn procyclical when firms face tight credit constraints a novel propagation mechanism thus emerges through its effect on the cyclical composition of investment tighter credit can lead to both higher volatility and lower mean growth evidence from a panel of countries provides support for the model s key predictions

optimal interest rate smoothing this paper considers the desirability of the observed tendency of central banks to adjust interest rates only gradually in response to changes in economic conditions it shows in the context of a simple model of optimizing private sector behaviour that assignment of an interest rate smoothing objective to the central bank may be desirable even when reduction of the magnitude of interest rate changes is not a social objective in itself this is because a response of policy to irrelevant lagged variables may be desirable owing to the way it steers private sector expectations of future policy

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

institutional causes macroeconomic symptoms volatility crises and growth countries that have pursued distortionary macroeconomic policies including high inflation large budget deficits and misaligned exchange rates appear to have suffered more macroeconomic volatility and also grown more slowly during the postwar period does this reflect the causal effect of these macroeconomic policies on economic outcomes one reason to suspect that the answer may be no is that countries pursuing poor macroeconomic policies also have weak institutions including political institutions that do not constrain politicians and political elites ineffective enforcement of property rights for investors widespread corruption and a high degree of political instability this paper documents that countries that inherited more extractive institutions from their colonial past were more likely to experience high volatility and economic crises during the postwar period more specifically societies where european colonists faced high mortality rates more than 100 years ago are much more volatile and prone to crises based on our previous work we interpret this relationship as due to the causal effect of institutions on economic outcomes europeans did not settle and were more likely to set up extractive institutions in areas where they faced high mortality once we control for the effect of institutions macroeconomic policies appear to have only a minor impact on volatility and crises this suggests that distortionary macroeconomic policies are more likely to be symptoms of underlying institutional problems rather than the main causes of economic

an optimizing is lm specification for monetary policy and business cycle analysis we ask whether relations of the is lm type can sensibly be used for the aggregate demand portion of a dynamic optimizing general equilibrium model intended for analysis of issues regarding monetary policy and cyclical fluctuations the main result is that only one change the addition of a term regarding expected future income is needed to make the is function match a fully optimizing model whereas no changes are needed for the lm function this modification leads to a dynamic forward looking model of aggregate demand that is tractable and usable with a wide variety of aggregate supply specifications theoretical applications concerning price level determinacy and gradual price adjustment are included

inflation zone targeting abstract we study optimal monetary policy design in a simple model that deviates from the linear quadratic paradigm and provides a rationale for the practice of inflation zone targeting we show that the presence of either zone quadratic preferences or a zone linear relationship between inflation and economic activity provides strong incentives to deviate from conventional linear policies we calibrate the model based on parameters for the united states and the euro area and employ a numerical dynamic programming algorithm to derive the optimal policies with this algorithm we examine the role of uncertainty model structure and relative preference towards economic stability in determining the width of the implied targeted inflation zone

the employment effects of credit market disruptions firm level evidence from the 2008 9 financial crisis this article investigates the effect of bank lending frictions on employment outcomes i construct a new data set that combines information on banking relationships and employment at 2 000 nonfinancial firms during the 2008 9 crisis the article first verifies empirically the importance of banking relationships which imply a cost to borrowers who switch lenders i then use the dispersion in lender health following the lehman crisis as a source of exogenous variation in the availability of credit to borrowers i find that credit matters firms that had precrisis relationships with less healthy lenders had a lower likelihood of obtaining a loan following the lehman bankruptcy paid a higher interest rate if they did borrow and reduced employment by more compared to precrisis clients of healthier lenders consistent with frictions deriving from asymmetric information the effects vary by firm type lender health has an economically and statistically significant effect on employment at small and medium firms but the data cannot reject the hypothesis of no effect at the largest or most transparent firms abstracting from general equilibrium effects i find that the withdrawal of credit accounts for between one third and one half of the employment decline at small and medium firms in the sample in the year

estimation and control of an optimization based model with sticky prices and wages abstract this paper provides estimates of an optimization based equilibrium model with sticky prices and wages the estimated model is used to analyse the welfare properties of various interest rate rules for conducting monetary policy an important feature of this model is that it involves a tradeoff between the variances of price and wage inflation and the output gap this tradeoff implies that it is desirable for the monetary authority to respond to wage inflation in addition to price inflation output and past interest rates when setting the current interest rate the issue whether wages and prices can be indexed to steady state inflation has important implications both for the characterization of optimal interest rate rules and interest rate volatility in particular optimal policy in the presence of indexation induces implausibly high steady state inflation

caution and conservatism in the making of monetary policy does society benefit from the delegation of monetary policy to cautious and conservative central bankers we offer a critical view on the delegation literature and relax seemingly innocuous assumptions about uncertainty and preferences first caution improves credibility but does not obviate the need for central bank conservatism second previous models of delegation have focused on suboptimal forms of conservatism we derive optimal concepts of conservatism that mitigate or eliminate any residual problem of credibility third we rationalize why credible monetary policy may be conducive to stable inflation and output

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

inflation targeting regimes abstract this paper divides the monetary frameworks of countries that use an inflation target to define their monetary framework into three different regimes i full fledged inflation targeting ii implicit price stability anchor and iii inflation targeting lite the regimes are differentiated by the clarity and credibility of the commitment to the inflation target the revealed preference for different regimes is related empirically to cross country structural differences in economic and financial development policy implications of moving from one regime to another are drawn especially for emerging market countries aiming at full fledged inflation targeting

targeting nominal income growth or inflation within a simple new keynesian model emphasizing forward looking behavior of private agents i evaluate optimal nominal income growth targeting versus optimal inflation targeting when the economy is mainly subject to shocks that do not involve monetary policy trade offs for society inflation targeting is preferable otherwise nominal income growth targeting may be superior because it induces inertial policy making which improves the inflation output gap trade off somewhat paradoxically inflation targeting may be relatively less favorable the more society dislikes inflation and the more persistent are the effects of inflation generating shocks jel e42 e52 f58

inflation dynamics marginal cost and the output gap evidence from three countries recent studies have argued that the new keynesian phillips curve calvo pricing model is empirically valid provided that real marginal cost rather than detrended output is used as the variable driving inflation one interpretation of this result is that real marginal cost is not closely related to the output gap and so models for monetary policy need to include labormarket rigidities an alternative interpretation is that marginal cost and the output gap are closely related but that the latter needs to be measured in a manner consistent with dynamic general equilibrium models to date there has been little econometric investigation of this alternative interpretation this paper provides estimates of the new keynesian phillips curve for the u s the u k and australia using theory consistent estimates of the output gap using this theory to measure the output gap leads to a considerable improvement in the empirical performance of output gapbased phillips curves

a cure for discrimination affirmative action and the case of california s proposition 209 proposition 209 enacted in california in 1996 and made effective the following year ended state affirmative action programs not only in education but also for public employment and government contracting this paper uses cps data and triple difference techniques to take advantage of the natural experiment presented by this change in state law to gauge the labor market impacts of ending affirmative action programs employment among women and minorities dropped sharply a change that was nearly completely explained by a decline in participation rather than by increases in unemployment this decline suggests that either affirmative action programs in california had been inefficient or that they failed to create lasting change in prejudicial attitudes

inflation targeting as a means of achieving disinflation in this paper we take an analytical approach to examine possible adverse effects of the use of inflation targeting as a disinflation regime the idea is that a strict interpretation of an inflation target may preserve inflationary distortions after price stability is attained we show that such a policy not only creates a slump in output but may increase macroeconomic volatility substantially in a model in which wages are subject to a taylor staggering structure

does exchange rate control improve inflation targeting in emerging economies abstract we investigate the role of exchange rates in inflation targeting emerging economies we give strong evidence that hybrid inflation targeting frameworks where exchange rate is managed deliver a stronger nominal anchor as they show better resistance to the 2007 2008 inflation shock

decomposing real and nominal yield curves abstract inflation indexed and nominal yield curves capture investors expectations of real short rates and inflation as well as their required compensation for bearing liquidity inflation and real interest rate risk we estimate an affine term structure model that allows us to decompose real and nominal bond yields into these components and use the model to study the transmission of monetary policy the model decompositions imply that the federal reserve s announcements of lsaps lowered yields primarily by reducing real term premia changes in real term premia also account for the strong response of long term real forward rates to federal funds rate surprises

state dependent pricing and the general equilibrium dynamics of money and output economists have long suggested that nominal product prices are changed infrequently because of fixed costs in such a setting optimal price adjustment should depend on the state of the economy yet while widely discussed statedependent pricing has proved difficult to incorporate into macroeconomic models this paper develops a new tractable theoretical state dependent pricing framework we use it to study how optimal pricing depends on the persistence of monetary shocks the elasticities of labor supply and goods demand and the interest sensitivity of money demand

british inflation and unemployment in the 1970s a model based decomposition the uks stagflation in the 1970s is decomposed into its causative factors using the liverpool rational expectations model it is found that there was a large rise in the natural rate of unemployment mainly due to rising union density that fiscal and monetary shocks had little effect on the resulting rise in unemployment and the high inflation of the period was due to persistent and large fiscal deficits with their accompanying monetization mrs thatcher inherited an inflation induced by an ongoing deficit and a natural rate of over 2 million unemployed

gender bias and credit access we extract an exogenous measure of gender bias from survey responses by descendants of u s immigrants on questions about the role of women in society we then use data on around 6 000 small business firms from 17 countries and find that in high gender bias countries female entrepreneurs are more likely to opt out of the loan application process and to resort to informal finance even though banks do not appear to actively discriminate against them these results are not driven by credit risk differences between female and male owned firms or by any idiosyncrasies in the set of countries in our sample

monetary policy rules under heterogeneous inflation expectations this paper evaluates the role of inflation forecast heterogeneity in u s monetary policymaking the deviation between private and central bank inflation forecasts is identified as a significant explanatory factor behind the fed s monetary policy decisions a discretionary policy rule that includes the forecast deviation as an additional argument is estimated empirically for the period 1975 2009 covering the chairmanships of arthur burns george miller paul volcker alan greenspan and the beginning of ben bernanke s term by using inflation forecasts obtained from the federal open market committee s greenbook and the survey of professional forecasters and real time estimates of the output gap the estimated rule appears to provide a consistent description of the fed s policy during the sample period presenting an alternative perspective regarding the key drivers of the high inflation phase in the 1970s as well as of the successful volcker disinflation in the early 1980s and the gradual transition to a regime of lower inflation and high policy credibility that has increasingly characterized monetary policy over the past two decades jel e50 e52 e58

education and labor market discrimination using a model of statistical discrimination and educational sorting we explain why blacks get more education than whites of similar cognitive ability and we explore how the armed forces qualification test afqt wages and education are related the model suggests that one should control for both afqt and education when compar ing the earnings of blacks and whites in which case a substantial black white wage differential emerges we reject the hypothesis that differences in school quality between blacks and whites explain the wage and education differentials our findings support the view that some of the black white wage differential reflects the operation of the

should inflation targeting central banks respond to exchange rate movements abstract this paper examines whether it is optimal for inflation targeting central banks to respond to exchange rate movements the paper finds that exchange rate movements can provide a signal on the developments in the economy that the central bank cannot perfectly observe the results suggest that when the degrees of exchange rate pass through and international financial integration are high it is optimal for the central bank to pay more attentions to exchange rate movements these results however depend on two conditions 1 the ability of the central bank to observe the true exchange rate process and 2 the number of real frictions in the model economy

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association
