who targets inflation explicitly abstract several countries have recently adopted explicit inflation targeting eit this paper applies probit analysis on data for 22 countries to show that the degree of central bank independence is positively correlated with the probability that inflation targeting is adopted there is also evidence depending on whether iceland and norway are included in the sample that the probability that eit is introduced is influenced by membership in the european union the commodity concentration and composition of exports which are correlated with measures of the importance of supply and external shocks and the degree of openness

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

does inflation targeting improve fiscal discipline abstract we explore the performances of inflation targeting it adoption in terms of fiscal discipline fd while most existing studies focus exclusively on the role of fd as a precondition for it adoption using a sample of developing and developed countries we show that it adoption exerts a positive and significant effect on fd a result robust to a wide variety of alternative specifications in addition this effect is statistically significant only in developing countries a result that may fuel the current debate regarding the relevance of it adoption in general and particularly for developing countries

impartiality priority and solidarity in the theory of justice the ethic of priority is a compromise between the extremely compensatory ethic of welfare equality and the needs blind ethic of income equality we propose an axiom of priority and characterize resource allocation rules that are impartial prioritarian and solidaristic they comprise a class of rules which equalize across individuals some index of resources and welfare consequently we provide an ethical rationalization for the many applications in which such indices have been used e g the human development index index of primary goods etc

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

a new analysis of a simple model of fair allocation in a recent article fragnelli and gagliardo fragnelli v gagliardo s 2012 cooperative models for allocating an object economics letters 117 227 229 propose several procedures to solve a basic problem of fair allocation we scrutinize their proposal and contextualize it into recent developments of the literature on bankruptcy problems our analysis supports two of the procedures they propose namely the shapley and talmud rules

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

the political economy of a divided ireland for a peace process in ireland to succeed it will require an active transition away from the underlying causes of conflict not just the partition of the country but the inequalities of opportunities and employment between the communities in northern ireland this requires the restructuring of existing unequal arrangements if this restructuring is not to be at the expense of the protestant community public intervention will be needed to ensure that opportunities for the protestant community can be developed alongside the necessary catching up of the previously disadvantaged community otherwise any type of future transition process risks grinding to a halt

economic growth and convergence in latin america little is known about the convergence process among developing countries in general and in latin america in particular for the period as a whole there is no evidence of a narrowing in the cross country dispersion of income sigma convergence but there is evidence of convergence to different steady state income levels at a speed that is common to all countries conditional beta convergence the article also shows that the estimates of convergence are sensitive to the way in which gdp per capita is measured

convergence and divergence in latin america 1970 1998 this paper examines the process of convergence in latin america over the period 1970 1998 there has been relatively little work on income convergence among developing countries in general and in latin america in particular even though many studies have examined convergence both within and among developed countries there is little support for the convergence hypothesis over the sample period as a whole although the beta coefficient is positive it is insignificant convergence is strong in the 1970s but by the 1990s it has disappeared there is no evidence of a narrowing in the cross country dispersion of income sigma convergence for the sample period as a whole the results offer little support for the neo classical growth model poorer countries have not grown faster than richer ones there is a strong case for strengthening regional development policy

the ups and downs of capitalism ben bernanke is a leading macroeconomist who has contributed extensively to the literature on business cycles monetary policy the role of financial markets in economic fluctuations inflation targeting and the economics of the great depression he is one of the six economists who form the nber business cycle dating committee a group that determines the dates of recessions in the us in this article interview professor bernanke discusses issues relating to the great depression of the 1930s and problems relating to inflation in the latter half of the twentieth century

returns to scale market power and the nature of price rigidity in new keynesian models with self fulfilling expectations increasing returns to scale and firms market power are two potential sources of sunspot expectations in neoclassical models we show that in new keynesian models returns to scale and market power can have fundamentally different implications for broad macroeconomic issues including self fulfilling expectations depending on the nature of price rigidity our findings suggest that the design of stabilization monetary policy can depend on precise knowledge about the economy s real and nominal features therefore a clear understanding of the specific economic environment and its relevance to monetary policymaking for ensuring macroeconomic stability can be an integrated part of monetary policy practice

inflation targeting as a monetary policy rule the purpose of the paper is to survey and discuss in ation targeting in the context of monetary policy rules the paper provides a general conceptual discussion of monetary policy rules attempts to clarify the essential characteristics of in ation targeting compares in ation targeting to other monetary policy rules and draws some conclusions for the monetary policy of the european system of central banks jel classi cation e42 e52

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 role of structural change in european regional productivity growth o leary e and webber d j the role of structural change in european regional productivity growth regional studies recent literature suggests that inter sectoral structural change has a negligible impact on aggregate productivity growth through the application of dynamic shift share methods this paper presents a re examination of this perspective using data for 181 european regions from 1980 to 2007 results suggest that the effect of the inter sectoral component is far from negligible and is substantially stronger for those regions towards the higher deciles of the distribution moreover its effects appear to be particularly growth enhancing when the region is either high and improving or low and deteriorating these results rehabilitate the importance of structural change for growth and convergence

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

cooperative models for allocating an object abstract this paper starts from a classical fair division situation of allocating an object among a set of agents the problem is studied from both a cooperative and a bankruptcy point of view analyzing the fairness properties of the proposed solutions

game theoretic analysis of a bankruptcy problem from the talmud abstract for three different bankruptcy problems the 2000 year old babylonian talmud prescribes solutions that equal precisely the nucleoli of the corresponding coalitional games a rationale for these solutions that is independent of game theory is given in terms of the talmudic principle of equal division of the contested amount this rationale leads to a unique solution for all bankruptcy problems which always coincides with the nucleolus two other rationales for the same rule are suggested in terms of other talmudic principles needless to say the rule in question is not proportional division

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

distributive justice in taxation abstract a classical criterion for apportioning taxes is that all should sacrifice equally in loss of utility suppose that a method of apportioning taxes is continuous and has the following four properties i the way that taxpayers split a given tax total depends only on their own taxable incomes ii an increase in the tax total implies that everyone pays more iii every incremental increase in tax is apportioned according to taxpayers current after tax incomes iv the ordering of taxpayers by pre tax income and after tax income is the same then there exists a utility function relative to which all sacrifice equally

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

mobility and modality trends in us state personal income we examine the mobility and modality trends in us state per capita personal income and its components during the 1929 1999 period we find strong evidence of convergence for states but that the tendency towards convergence and the associated mobility within the distribution varies during the period and especially for the 1980s our analysis of convergence by income component suggests that transfer income contributes more to the observed convergence than does asset income we also note that distributional mobility need not be accompanied by high rank mobility and find that trends toward convergence in the us have tended to preserve rank ordering cet article cherche a examiner les tendances de mobilite et de modalitequant aux revenus personnels par tete et a ses composants aux etats unis pendant la periode qui va de 1929 a1999 il s avere de fortes preuves d une convergence entre etats qui varie au cours de la periode etudiee et qui va de pair avec une variation de la mobilite associee au sein de

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

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

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

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

does inflation targeting make a difference in developing countries we evaluate the treatment effect of inflation targeting in thirteen developing countries that have adopted this policy by the end of 2004 using a variety of propensity score matching methods we show that on average inflation targeting has large and significant effects on lowering both inflation and inflation variability in these thirteen countries however the effectiveness of inflation targeting on lowering inflation is found to be quite heterogeneous the performance of a given inflation targeting regime can be affected by country characteristics such as government s fiscal position central bank s desire to limit the movements of exchange rate its willingness to meet the preconditions of policy adoption and the time length since the policy adoption

equality of resources implies equality of welfare if one is an egalitarian should one try to equalize resources available to agents or to equalize their welfares with a suitably general conception of what resources are these two conceptions cannot be distinguished an allocation mechanism is defined on a space of economies and is required to satisfy various axioms that are necessary conditions for equalizing resources among a population the unique mechanism satisfying these axioms on a large domain of economies is the one that allocates commodities so as to equalize utilities of the agents methodologically the theorem is a generalization of bargaining theory because the mechanisms are defined on commodity space

welfare bounds in the fair division problem to any anonymous division method corresponds a lower and an upper bound function they measure the impact on a given agent s utility of the other agents preferences the highest lower bound is the equal split utility the lowest upper bound is the indirect utility from equal split at a canonical price these two bounds are compatible yet any method with the elqual split lower bound exhibits the growth paradox and any method with the lowest upper bound generates envy we criticize competitive equilibrium from equal split because it puts no finite upper bound on any agent s welfare

an assessment of inflation targeting in a quantitative monetary business cycle framework evidence from four early adopters this article examines the effectiveness of inflation targeting it to stabilize the real economy in advanced countries where it was adopted in the early 1990s to quantitatively assess it this article employs the monetary business cycle accounting methodology recently developed by sustek 2011 which is an extended version of chari kehoe and mcgrattan 2007 to monetary models our main finding is that the monetary policy wedge that captures economic fluctuations caused by monetary policy has significantly declined since the implementation of it in the early 1990s the results suggest that advanced economies such as australia canada sweden and the united kingdom that adopted it in the early 1990s have been successful in stabilizing business cycle fluctuations

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 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

allocation rules for a commonly owned technology the average cost lower bound assume that a set of individuals commonly own a one input one output technology at an average cost pricing equilibrium allocation the consumption contribution ratio is identical among agents and each agent maximizes her welfare given this ratio the following requirement is introduced every agent must be as well off at a selected allocation as at the average cost equilibrium that all agents prefer the paper establishes compatibilities and incompatibilities between this requirement and some traditional requirements finally the new lower bound is combined with properties such as technological monotonicity or contraction independence to characterize mas colell s constant returns equivalent allocation rule

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

is forward looking inflation targeting destabilizing the role of policy s response to current output under endogenous investment we show that with endogenous investment virtually all monetary policy rules that set a nominal interest rate in response solely to expected future inflation induce real indeterminacy in models with i staggered prices ii staggered prices and staggered wages and iii staggered prices staggered wages and firm specific capital in i policy s response to current output can help significantly in ensuring determinacy with an infinite labor supply elasticity but little with empirically plausible labor supply elasticity in ii responding to output always helps a great deal though under low price stickiness and without capital adjustment cost it may call for a moderate response to output in order to ensure determinacy for a wide range of response to inflation in iii even a tiny response to output can always render equilibrium determinate for a wide range of response to inflation

politics and business cycles in industrial democracies politics alberto alesina influences from political competition on macroeconomic policy are often thought to be a source of economic fluctuations politicians are described as being driven by two not mutually exclusive main motivations they want to be reelected and they harbour political or ideological biases when such theories are confronted with actual cycles in a number of industrial countries the pattern of inflation unemployment output and budget deficits indicates that partisan policy making is a fairly widespread phenomenon with more limited evidence that electoral preoccupations result in major fluctuations the combination of partisanship and electoral cycles may easily result in socially undesirable outcomes in particular the degree of politico institutional stability and the independence of the central bank have a bearing on macroeconomic outcomes these observations raise a number of important questions about the design of political institutions

political and monetary institutions and public financial policies in the industrial countries institutions and policies vittorio grilli donato masciandaro and guido tabellini why do countries as similar as the industrialized oecd countries go through such different experience in terms of public deficits and debts or in terms of inflation the answer cannot come from macroeconomic policy responses to different disturbances nor from the principles of optimal taxation but rather from politics this article focuses on the role that particular institutions exert in providing constraints and incentives which shape the actions of policymakers the electoral process and political traditions affect the ability of governments to deal with deficits and mounting debts what seems to matter most it is found is the effect of the durability of governments governments with short horizons act myopically and never quite tackle the hard choices such governments typically exist in countries with an electoral system favouring many small political parties central bank independence promotes low inflation with no apparent costs in terms of real economic performance irrespective of the political institutions in fact there is no link between monetary and fiscal discipline these findings carry powerful implications for countries facing high indebtedness or stubborn inflation but also for the construction of the european economic and monetary union

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

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

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

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

what matters when the impact of ecb communication on financial market expectations this article analyses financial markets reaction to european central bank s ecb communication we apply a novel indicator that quantifies the contents of the ecb s introductory statements and allows disentangling ecb statements on prices the real and the monetary sector we provide evidence that it matters what issue the ecb is speaking about especially the ecb s statements on price developments represent important news to financial markets it also matters when the ecb affects markets communication drives maturities above 4 months

differences in gdp per head in gb counties some suggested explanations this paper examines the evidence concerning the convergence of gross domestic product gdp per head across gb counties during 1977 1995 in general the evidence rejects the hypothesis of convergence although there is some evidence of a north south divide with convergence in the north in the 1990s cross section results suggest that variation in gdp per head may be related to different economic activity rates and some aspects of industrial structure
