how delegation improves commitment abstract mccallum 1995 american economic review papers and proceedings 85 2 207 211 conjectures that delegation merely relocates the commitment problem but does not solve it this holds if optimal ex ante policies do not change if additional information becomes available however with a flexibility credibility trade off delegation improves credibility

rogoff s conservative central banker restored we show that delegation of monetary policy to a weight conservative central banker can be desirable although the government can also use an inflation contract an employment target an inflation target or any combination of these to control the central banker the key feature of our model is a stochastic inflation bias arising when wage setters receive some information about a supply shock prior to signing nominal wage contracts weight conservatism is found to be desirable if fully state contingent delegation is not possible and the stochastic inflation bias cannot be eliminated by optimal choice of the delegation parameters

aggregate demand shocks central bank preferences and macroeconomic outcomes with imperfect information abstract assuming imperfect information regarding aggregate demand shocks the paper shows first the distribution of the impact of such shocks between employment and prices depends crucially on central bank preferences second optimal stabilization is achieved by a conservative central banker

should renewable energy policy be renewable political flexibility brings about trade offs for policy makers aiming to support the deployment of renewable energy sources res on the one hand it allows incorporating new information on ex ante uncertain benefits and costs of res policy on the other hand it may deter res investments this paper scrutinizes how these trade offs play out economically and politically when res policy makers choose the degree of flexibility as well as the instruments to implement flexibility the analysis builds on a theoretical framework distinguishing between flexibility by design and by adjustment it is complemented by a discussion of three case studies res support schemes in germany and the united kingdom and the eu emissions trading scheme theoretical as well as empirical results suggest that the politically chosen degree of flexibility by policy design may be sub optimally low in contrast flexibility by policy adjustment is often excessively high

pegged exchange rate regimes a trap this paper studies the empirical and theoretical association between the duration of a pegged exchange rate and the cost experienced upon exiting the regime we confirm empirically that exits from pegged exchange rate regimes during the past two decades have often been accompanied by crises the cost of which increases with the duration of the peg before the crisis we explain these observations in a framework in which the exchange rate peg is used as a commitment mechanism to achieve inflation stability but multiple equilibria are possible we show that there are ex ante large gains from choosing a more conservative not only in order to mitigate the inflation bias from the well known time inconsistency problem but also to steer the economy away from the high inflation equilibria these gains however come at a cost in the form of the monetary authority s lesser responsiveness to output shocks in these circumstances using a pegged exchange rate as an anti inflation commitment device can create a trap whereby the regime initially confers gains in anti inflation credibility but ultimately results in an exit occasioned by a big enough adverse real shock that creates large welfare losses to the economy we also show that the more conservative is the regime in place and the larger is the cost of regime change the longer will be the average spell of the fixed exchange rate regime and the greater the output contraction at the time of a regime change

the institutional foundations of monetary commitment a comparative analysis abstract this paper adopts an institutional perspective on the problem of designing governance structures for restraining monetary policy this perspective broadens the standard literature on central bank independence in several dimensions first although it recognizes that an independent central bank is one important institutional arrangement it also considers a much broader variety of institutional arrangements that have been used historically and today to restrain monetary policy second it considers not only the formal or legal institutional arrangements governing monetary policy but also the broader environment or institutional endowment in which those formal arrangements are embedded third this paper is concerned with the problem of enforcement given the institutional endowment in which formal monetary rules are implemented how likely are they to stick broadening the perspective in these ways frames the issue as a matching problem when it is recognized both that countries differ in the nature of their institutional endowments and that there is an array of possible formal arrangements that can be adopted to govern monetary policy the question then becomes how best to align the formal arrangements with the endowment in which they will be embedded case studies of diverse monetary policy making institutions in cote d ivoire argentina thailand and new zealand are used to motivate and illustrate the analysis

issues in new political economy an overview a brief overview of the historical background nature and rapid growth in volume and scope of new political economy since the early 1980s is provided the paper continues with some general reflections on the strengths and weaknesses of the new political economy approach illustrated by the other contributions to this special issue of the journal of economic surveys the final section summarises these contributions

time consistent collection of optimal seigniorage a unifying framework this paper reviews the existing literature on the time consistency problem of seigniorage collection when monetary policy is determined by optimal taxation considerations it develops a unifying accounting framework and suggests a general measure for seigniorage which encompasses the standard measures employed in the literature in addition the ex ante optimal solution to the optimal taxation problem is derived and interpreted in relation to the ramsey principle we show that the different recommendations of the public finance literature i e the friedman rule of optimal deflation moderately positive inflation and seigniorage maximizing inflation are specific solutions to the optimal taxation problem the paper continues with a formal illustration of the time consistency problem of the ex ante optimal policy and the characterization of the time consistent solution under discretion as possible solutions to the time consistency problem we consider reputational forces institutional reforms that establish central bank independence and specific ways of asset and debt management in particular it is formally shown that a modified version of the asset and debt management scheme suggested by persson persson and svensson is not only necessary but also sufficient for optimality although this did not hold in their model

when and how much to talk credibility and flexibility in monetary policy with private information abstract this paper analyzes the role of noisy or imprecise announcements in mitigating the basic credibility problem in monetary policy based on a model where the monetary authority s private information gives rise to an unavoidable trade off between flexibility and credibility the analysis finds that noisy announcements can serve as a meaningful form of communication to make that trade off more favorable however such talk is not cheap the analysis predicts that those central banks who can speak more precisely are those who are less likely to speak at all

destabilizing effects of exchange rate escape clauses abstract this paper studies policy rules with escape clauses analyzing as an example fixed exchange rate systems that allow member countries the freedom to realign in periods of stress while well designed escape clause rules can raise society s welfare in principle limited credibility makes it difficult to implement such rules in practice an ems type institution that imposes political costs on policymakers who realign may raise welfare but can also produce equilibria far inferior to an irrevocably fixed exchange rate switches between multiple equilibria may have the character of sudden speculative attacks

the effectiveness of monetary policy anchors firm level evidence analyses of monetary policy posit that exchange rate pegs inflation targets and central bank independence can help anchor private sector inflation expec tations yet there are few direct tests of this argument we offer cross national micro level evidence on the effectiveness of monetary anchors in controlling private sector inflation concerns using firm level data from eighty one countries approximately 10 000 firms we find evidence that international anchors exchange rate commit ments correlate significantly with a substantial reduction in private sector concerns about inflation while domestic anchors inflation targeting and central bank inde pendence do not our conjecture is that private sector inflation expectations are more responsive to exchange rate anchors because they are more transparent more con straining and more costly than domestic anchoring arrangements the literature on monetary policy highlights the role of monetary institutions in stabilizing private sector inflation expectations central bank independence cbi inflation targeting it and fixed exchange rates pegs are widely viewed as insti tutions that have the capacity to mitigate private sector concerns that policymak ers will exploit them after they have locked in their price wage and investment decisions while other empirical research explores the institutional correlates of inflation and its variability yielding mixed results we use firm level data in our study to directly assess the impact of monetary anchors on private sector inflation concerns we find evidence that pegs mitigate firm owners concerns with infla tion but that domestic anchors such as it and cbi are uncorrelated with our micro indicators of inflation expectations considerable research has investigated the use of it cbi and pegs as institu tions that establish monetary policy credibility whereas these anchors are expected

the information content of the reserve bank of australia s inflation forecasts in this article the inflation forecasts produced by the reserve bank of australia rba and that generated by private forecasters are used to assess whether the reserve bank possesses information about inflation that the private sector does not have the results show that the reserve bank inflation forecasts embody useful predictive information about inflation beyond that contained in private forecasts over the recent inflation targeting period

independent monetary policies and social equity monetary policy is formulated as a game between the government and the central bank we show that when fiscal policy has a redistributional component there is a conflict between optimally configured monetary policies and equality consequently inflation averse governments interested in social equity will need to limit their use of fiscal policy

congressional influence on u s monetary policy abstract congressional influence is generally discounted or ignored in political models of federal reserve behavior here i show that changes in the leadership of the senate banking committee are significantly correlated with monetary base growth more liberal committee leaders are associated with significantly higher base growth other factors held constant the result is shown to hold across several econometric specifications and different definitions of the congressional preference variable

the european central bank independence accountability and strategy a review this paper reviews research on central banking and monetary policy with special emphasis on the position of the future european central bank nowadays it is often thought that an independent central bank with an explicit mandate to aim for price stability constitutes an important institutional device to assure price stability indeed the ecb will be one of the most independent central banks as follows from the codings of various indicators measuring legal independence still it does not follow straightforwardly from the literature that the statute of the ecb is optimal it is also argued that the accountability of the ecb is poorly arranged for in comparison with that of several national central banks finally the discussion about the monetary strategy of the ecb is reviewed

variation in central bank independence across countries some provisional empirical evidence in this paper seven hypotheses to explain variation in central bank independence across countries are tested the predictions based upon the theory that delegation of authority by politicians to the central bank is used as a commitment device are not supported central bank independence is not higher the larger the employment motivated inflationary bias the higher political instability or the larger the government debt central bank independence is positively related to historical inflation experience and negatively with political instability we do only find limited support for the view that countries with a universal banking system and countries whose central banks do not regulate financial institutions have more independent central banks

the limits of independence and the policy of the ecb it is argued that the european central bank s independence is not as secure as it seems and that as a result it has appreciable institutional incentives to protect and enhance its position it follows that its behaviour should not be understood as being solely determined by the pursuit of price stability one consequence is that certain points on which it has been criticised on the basis that its approach makes for ineffective monetary policy might be better understood as often effective attempts to protect its position another is that making a central bank or any other institution completely independent may be much harder than it seems and failed attempts which come close are not necessarily to be preferred even by the advocates of independence to less ambitious designs

central banking as a political principal agent problem i introduction conventional wisdom holds that during election periods political leaders have incentives to misuse policy instruments to enhance their chances of reelection rogoff and sibert 1988 construct a rational political economy model of monetary policy based on this theme 1 the results of their model can be interpreted in the following way 2 society elects a leader every other period whose competence affects the level of output in the economy and private agents will tend to vote for the incumbent if the level of output is expected to be higher than that which can be provided by an unknown challenger voters have imperfect information regarding the politician s true impact on output and exogenous shocks to output and consequently cannot disentangle the effects of one from the other in an election period this asymmetry of information gives the incumbent an incentive to expand output through the use of inflationary monetary policy in order to appear more competent than he really is however rational voters are aware of this incentive to inflate and adjust their expectations such that in equilibrium no gain in output occurs and the economy suffers from excessive inflation an implication of the rogoff sibert model is that unless a society does away with elections as a way to choose policymakers excessive inflation and a political inflation cycle will be an unavoidable cost of democracy however societies can try and have tried to avoid these ill effects by taking the power of money creation away from the elected officials and giving it to an appointed independent central banker who will presumably pursue the public good but can this approach actually work the problem with this proposal is that the central bankers well being in many respects reappointment post central bank employment opportunities avoidance of public criticism etc often hinges on pleasing their political benefactors giving the central bankers incentives to act in the interest of elected officials 3 as a result the central banker could pursue objectives different from society s and may actually function as a veil for the elected policymaker in the real world this veil is not complete but partial and hence we can characterize the relationship between the monetary authority and society as a principal agent problem the advantage of delegating power to an appointed central banker and then erecting appropriate institutions is that the inflation problems may be resolved without abandoning the electoral process in this paper we develop a rational political business cycle model that starts from the foundations laid down by rogoff and sibert we depart from their model by having monetary policy delegated to a central banker who is appointed by the elected leaden the concern about reappointment is what motivates the agency problem the central banker would like to be reappointed and this desire leads her to partially accommodate the wishes of the current administration which in turn may not coincide with the desires of the electorate we then analyze the problem faced by a central banker who is concerned about her own selfinterest as well as social well being it is this feature that turns the setting of monetary policy into a political principal agent problem the contributions of our approach to modelling the agency problem of central banking are 1 it explicitly incorporates reappointment concerns into the decision process of the central banker which heretofore has not been done in the literature and 2 we explicitly model the source of the agency problem unlike previous research that simply assumes an agency problem exists our key results are as follows in equilibrium the pursuit of her own self interest leads the central banker to create a socially inefficient inflation bias while rogoff and sibert also obtain this result our explicit functionalform model allows us to analyze this bias in more detail and tie it directly to the strength of the relationship between the central banker and the current administration

the flexible few oligarchs and wealth defense in developing democracies based on an original large n dataset of individual ukrainian oligarchs and qualitative evidence this article tests competing perspectives on the political power of big capital we find surprising

partially independent central banks politically responsive governments and inflation theories of central bank independence have more exact implications regarding inflation in different political economic environments than generally understood or empirically examined they imply that inflation in any given country time will be a weighted average of what it would be if the central bank completely controlled monetary policy and what it would be if the government completely controlled it with the degree of central bank independence weighting the former an equation embodying this theoretical expectation is estimated by constrained least squares from a time series cross section of inflation rates in developed democracies since the bretton woods era the results confirm that the antiinflationary benefit of central bank independence is not constant but rather depends on every variable in the broader politicaleconomic environment to which wholly autonomous central banks and governments would respond differently conversely the inflationary impacts of all such political economic variables depend on the degree of central bank independence

optimal monetary policy rules in a rational expectations model of the phillips curve using a rational expectations model based on a phillips curve with persistence in inflation we derive optimal monetary policy rules under both commitment and discretion we assume that the central bank targets the natural rate of output so there is no incentive generating an average inflation bias with commitment inflation has less persistence but more conditional variability whereas output has more persistence and less conditional variability than with discretion as the commitment strategy stabilizes the systematic component of inflation it is less responsive to random shocks to inflation

optimal reputation building in the new keynesian model abstract we study the optimal committed monetary policy when the private sector has imperfect information and has to infer the central banker s ability to commit the optimal policy is designed to influence learning and improve the central banker s reputation of being committed the reputation building implies that when a committed central banker first takes office he should resist the temptation to stimulate output with initially high but declining inflation he should reverse a missed inflation target rather than accommodate it and he should adopt a less accommodative inflation response to a cost push shock than a full commitment solution suggests

public inflation aversion and the political economy of macroeconomic policymaking do the macroeconomic priorities of citizens differ across countries if so what accounts for this variation and what are its consequences for explanations of the choice of monetary institutions macroeconomic policy and international monetary cooperation this article uses survey data from twenty advanced economies to examine individual preferences about macroeconomic priorities the analysis establishes three key findings first the results suggest that economic context defined by inflation and unemployment performance has a substantial impact on the public s economic objectives in a way that is broadly consistent with the specification of utility loss functions in the theoretical political economy literature second the results suggest that there is significant cross country variation in inflation aversion controlling for economic context third some of this variation is accounted for by national level factors affecting the aggregate costs of inflation and unemployment these results have significant implications for optimal monetary policymaking the explanation of variation in economic outcomes and for accounts of the choice of institutional frameworks for policymaking i thank the bank of england the center for basic research in the social sciences and the institution for social and policy studies for research support and jim alt andrew bailey bill bernhard lawrence broz john freeman jeff frieden jim granato shigeo hirano david lake jeff lax simon price rose razaghian ron rogowski david stasavage gabriel sterne mike tomz jim vreeland the editor and two anonymous reviewers for helpful comments all views expressed are those of the author and do not represent those of the bank of england

a political model of monetary policy with application to the real fed funds rate abstract we construct an empirical model of u s monetary policy assuming that the federal reserve is an ordinary federal bureaucracy we use the real federal funds rate as our policy measure and show the existence of significant executive legislative and bureaucratic influence on the real rate of interest from 1961 to 1996 we find that presidential party is an adequate statistical measure of executive influence and that the voting scores of the senate banking committee leadership best represent legislative influence we argue that political changes cause systematic and predictable changes in monetary policy

tick size and spreads the case of nasdaq s decimalization abstract recent studies by the securities and exchange commission sec and by academics have provided empirical evidence that nasdaq trade execution costs are still higher than for instance on the nyse introducing decimal pricing is one concrete plan to enhance nasdaq s competitiveness however effects of tick size changes are difficult to predict for that reason models have been required for quite a while capital market synergetics is appropriate to investigate the effects of market microstructure changes in this paper we examine the impact of a variation in nasdaq s minimum price increment on quoted spreads first our findings confirm the numerical value of the decline in the average quoted spread in 1997 as an immediate effect of reducing the tick size from 1 8 to 1 16 this strongly affirms the reliability of our calculation results second by applying the same research design again we investigate the impact of a further reduction in the tick size to 1 100 no such study is available at the moment the expected changes in the average quoted spreads due to the reduction in the tick size from 1 16 to 1 100 the change through decimalization range from an increase of 2 82 to a decrease of 15 51 derived by applying the same method again the figures embody a reliable forecast of the real effects and are therefore of eminent importance to academics and to practitioners as well

a bargaining model of partisan appointments to the central bank abstract in this paper a bargaining model is developed to analyze the appointment of central bankers in a two party political system the major results of the paper are 1 the party in power will appoint partisans early on but later appointments will be increasingly moderate in their views concerning monetary policy 2 changing the timing of the appointment of the board chairman from the end of a president s term in office to the first period of the president s term will lead to more partisan monetary policy 3 in equilibrium nominations to the board are not rejected thus confirmation hearings appear to be nothing more than a rubber stamp process 4 lengthening the terms on the board relative to the electoral cycle will lead to more moderate appointments to the central bank and a reduction in partisan policymaking

dynamic commitment and incomplete policy rules considering the dynamics of commitment highlights some neglected features of time inconsistency problems we modify the standard rules versus discretion question in three ways 1 a government that does not commit today retains the option to do so tomorrow 2 the government s commitment capability is restricted to a class of simple rules and 3 the government s ability to make irrevocable commitments is restricted three results stand out first the option to wait makes the incumbent regime rules or discretion relatively more attractive second the option to wait means that increased uncertainty makes the incumbent regime more attlwactive third because the commitment decision takes place in real time policy choice displays hysteresis when monetary policy is subject to dynamic inconsistencies optimal policy requires some precommitment by the central bank despite a proliferation of mechanisms designed to address this problem work in this area has continued to assume a once and for all choice between rules and discretion this paper asks two closely related questions first what happens if commitment decisions are made in real time so that failure to commit today does not rule out the possibility of commitment tomorrow second if governments can make only commitments that are difficult but not impossible to reverse what determines the dynamics of commitment and reversal the assumption of once and for all choice enforces simplistic dynamics on the policy process if the standard models are interpreted literally for example the commitment problem for u s monetary policy is moot having been resolved with the founding of the federal reserve system in 1914 if not at the constitutional convention of 1789 much of the interest in dynamic inconsistency however arises pre

the inflationary bias in a model of the open economy a note abstract in this paper we highlight the importance of aggregate supply effects on the size of the inflationary bias under discretionary policy making using a simple model of an open economy that imports a foreign resource input we show that under discretion the inflationary bias bears an inverse relationship to the elasticity of output supplied with respect to the real exchange rate this theoretical finding is consistent with romer 1993 romer d 1993 openness and inflation theory and evidence quarterly journal of economics 108 869 903 empirical results that point to the existence of a negative association between openness and inflation

who supports the ecb evidence from eurobarometer survey data this paper contributes empirically to the long debated issue of the legitimacy of the european central bank ecb with regard to european polities using micro level data from the eurobarometer survey we shed light on the socio demographic determinants of public opinion support for the ecb we find that people with higher level of education and income and centre to right wing political orientation tend to support the ecb as well as people with optimistic expectations on the economic situation by contrast the unemployed tend to distrust the ecb the policy relevance of such results is important for ecb s communication strategy with the general public

classifying monetary economics fields and methods from past to future we propose a simple yet sufficiently encompassing classification scheme of monetary economics it comprises three fundamental fields and six recent areas that expand within and across these fields the elements of our scheme are not found together and in their mutual relationships in earlier studies of the relevant literature neither is this an attempt to produce a relatively complete systematization our intention in taking stock is not finality or exhaustiveness we rather suggest a viewpoint and a possible ordering of the accumulating knowledge our hope is to stimulate an improved understanding of the evolving nature and internal consistency of monetary economics at large

on the impossibility of central bank independence four decades of time and intellectual inconsistency the intellectual justification for modern central banking time inconsistency celebrated its fortieth anniversary in 2017 alongside the cambridge journal of economics however the key progeny of the time inconsistency literature central bank independence has fundamental flaws that have been thus far neglected in mainstream research in the first instance the argument for independence relies on a utilitarian rather than institutional analysis one that neglects the genesis of central banks and their relation to other institutions within a country second central bank independence neglects the complex interdependencies of the global monetary and financial system applying an institutional lens to the concept of central bank independence i conclude that independence fails under the reality of globalization as much as it does in a domestic context with central banks reliant on all manner of political institutions they are never really independent operationally or in terms of policy

do we really want an independent central bank the issue of an independent central bank is assessed in the context of experience in the u k economy the historical role of the bank of england is examined revealing that the success of anti inflation policy depends on the exchange rate regime as well as on the institutional arrangements holding between the bank and government inflation targets are discussed but independence is also addressed by seeing how other targets such as nominal gdp might perform the theoretical arguments for and against an independent central bank are discussed in detail it is argued that partial independence where the central bank enjoys autonomy in relatively good states and is overridden in bad states is the preferred form of independence attention is drawn to the costs arising owing to a lack of coordination of policy when the finance ministry may compete against the central bank in the case where the latter is independent copyright 1994 by oxford university press

policy preferences of fomc members as revealed by dissenting votes the composition of the federal open market committee the ability to predict the effect of policy decisions on economic and f1nancialvariables and political influence from the white house and the congress are all potentially significant determinants of monetary policy decisions this study uses the record of dissenting votes from federal open market committee meetings to consider the relevance of these influences tests for differences between voting patterns of bank presidents versus members of the board of governors and differences during various historical periods provide insight into four questions 1 are the policy preferences of bank presidents different from those of the members of the board 2 does uncertainty about the economic and financial results of policy actions influence the level of dissent 3 is there a difference in the pattern of dissent under different chairmen and 4 is there effective political influence on monetary policymakers the legitimacy of district bank presidents serving on the fomc has been challenged in the courts and the legislature challengers fear that district bank presidents who serve without executive or legislative approval prefer policy that produces lower inflation and higher unemployment relative to the policy preferred by members of the board who are appointed by the president and confirmed by the senate rogoff 1985 argues that in the presence of market distortions it is better for society to have central bankers who attach a larger weight than the society s

inflation taxes and the coordination of monetary and fiscal policy by use of a game of chicken in this study some of the consequences of an uncertain policy struggle game of chicken between independent taxing agencies a monetary and a fiscal authority are exam ined we show that policy uncertainty may improve upon regimes where there is no uncer tainty and one agency succeeds in implementing a low tax policy at the expense of the other agency an uncertain tax policy never dominates a fully coordinated tax policy but it can move average tax rates in the right direction in this sense the game of chicken between agencies can be beneficial and can compensate for the lack of a specific coordinating admin

accountability transparency and inflation targeting inflation targeting regimes define a performance measure for the central bank a regime that places a large small weight on achieving the target is analogous to a high low powered incentive scheme high powered incentive structures promote accountability but may distort stabilization policy the optimal power under inflation targeting is derived under perfect and imperfect information the fundamental trade off between accountability and stabilization depends on the degree of transparency defined as the ability to monitor the central bank s performance multiplicative uncertainty increases the optimal weight to place on achieving an inflation target
