expectations the exchange rate and the current account abstract a critical examination is undertaken of the relationship between the exchange rate and the current account in a small open economy theoretically the correlation between the exchange rate and the current account seems to be ambiguous in particular the association between movements in the exchange rate and the current account is likely to depend in an essential manner on the nature of exogenous disturbances affecting the two variables simultaneously lastly the question of the role of an optimal monetary policy and the choice of an exchange rate regime in an uncertain environment is raised

fiscal policies in the world economy this paper uses a two country general equilibrium model of the world economy in order to analyze the effects of budget deficits and government spending on world rates of interest consumption and international indebtedness it demonstrates the difference between the effects of fiscal expenditures and tax cuts as well as between the effects of current policies and expected future policies it is shown that the qualitative effects of fiscal policies depend on whether the country introducing the policies runs a surplus or a deficit in its current account following the positive analysis of the short run and the steady state effects the paper concludes with a normative analysis of the welfare implications of budget deficits

is the european community an optimal currency area optimal taxation versus the cost of multiple currencies the authors propose a view of optimal currency areas that is based on the principles of public finance inflation taxes are distortionary and an optimal spreading of tax distortions may require high inflation in one region and low inflation in another each region would need its own currency to do this on the other hand multiple currencies imply valuation and currency conversion costs which impede trade between regions this tradeoff is explored in the context of the european community s debate over a common currency using a two country variant of robert lucas and nancy stokey s cash in advance model copyright 1990 by american economic association

on the complementarity of commercial policy capital controls and inflation tax this paper studies the optimal use of distortive policies aimed at raising a given real revenue in a general equilibrium framework in which lump sum taxes are absent the policies analysed are an inflation tax commercial policy and an implicit tax on capital inflows it is shown that we would tend to avoid activating an inflation tax for small revenue needs if the policy target were allocative we would tend to use only one policy instrument thus each policy has its own comparative advantage and their combined use is justified when the target is raising government revenue

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

an exploration in the theory of exchange rate regimes three exchange rate regimes a float a one sided peg and a cooperative peg are evaluated and compared in terms of efficiency and welfare levels the framework of analysis embodies country specific monies with the money of each country being used to transact in its commodity markets and its currency denominated bonds welfare levels depend only on consumption levels in the presence of perfect foresight all equilibrium allocations are pareto efficient in a floating exchange rate regime the perfect foresight equilibrium allocation coincides with an equilibrium of a costless barter economy the same result holds in a one sided peg if the pegging country s exchange rate stabilizing authority breaks even over time in a cooperative peg regime there is a different equilibrium allocation for each combination of exchange rate levels and monetary policies problems of policy coordination and conflicts in desired monetary policies are discussed

trends in rankings of economics departments in the u s an update economics departments in the u s are ranked based on 1 the number of pages published in thirty six economics journals 2 publications in five of the top journals 3 output per faculty member and 4 an index of the concentration of research in a department evidence shows that the top twenty departments have generally retained their positions since the 1970s but rather large changes have occurred in departments ranked from 240 to 100 an economists hall of fame is developed listing the top fifty individual producers of research in the thirty six journal set and the top five journals

exchange rate management intertemporal tradeoffs exchange rate management is possible only if the government pursues consistent monetary and fiscal policies the authors constructa model in which the real consequences of exchange rate management depend on the precise time pattern of these policies the authors study the constraints on feasible policies and the comparative dynamics of disinflation by means of exchange rate targeting theoretical results are consistent with exchange rate managed disinflation attempts in argentina chile and israel copyright 1987 by american economic association

do economics departments search optimally in faculty recruiting i introduction when an economics department decides to recruit new faculty it must decide in which fields to conduct the search casual observation suggests that the scope of recruiting searches varies widely with some departments searching primarily in a narrow subfield and others searching in several general or even all fields it is generally recognized that the very top departments tend to engage in very wide best athlete searches among departments that engage in narrower searches on the other hand it is not uncommon to hear complaints ex post that the search should have been broader is it therefore the case that these departments are making a suboptimal choice to search narrowly it would seem however that economic departments more so than other departments should be making economically rational decisions when choosing search scope 1 in this article we develop a simple model of how economics departments can optimally choose search scope in faculty recruiting we show that the optimal search scope is increasing in the quality rank of the department we use postings in job openings for economists joe to estimate the relationship between department rank and search scope and find that higher ranked departments engage in broader searches than lower ranked departments the relationship is robust to the exclusion of the top ranked departments from the sample because there is some debate about how well various department rankings reflect true department quality we instrument a reputation based ranking with a publication based ranking to correct for measurement error we find that a 10 place difference in department ranking is associated with 3 5 4 8 more journal of economic literature jel subfields in a position announcement ii the model we consider a simple model of a department s choice of the number of fields to search and show that the optimal number of fields searched is increasing in department quality other work on employer search has noted the benefits to some employers of broadening the applicant pool much like our finding that departments with higher quality standards will search more broadly barron et al 1985 show that employers will search over more candidates and or more intensively if the education requirements for the position are high barron et al 1997 argue that there is greater variation in productivity at higher levels of human capital therefore it is optimal for employers searching for workers with more formal education to spend more on search lang 1991 shows that employers for whom a job vacancy is the most costly will offer a higher wage therefore increasing the number of prospective applicants because the need to decide ex ante the fields to advertise in joe largely precludes the use of sequential search methods our model is essentially a fixed sample size search problem a key feature of our model is that each department has a quality cut off that reflects the department s ranking higher ranked departments will have higher quality cut offs applications below this cut off are thrown out without cost and applications above the cut off are reviewed more extensively with some positive cost 2 therefore if a high ranked department with a high quality cutoff searches narrowly it may not receive any applications above its cut off in addition because the higher ranked department can ignore most applications without cost the cost involved in expanding the search to other fields is lower than those incurred by lower ranked departments with lower cut offs these two effects will be important in explaining why a higher ranked department is better off expanding its search to more fields to formalize the model there are i 1 m fields in which a department can conduct its search each field searched by the department produces one applicant whose quality q sub i is a random draw from a uniform distribution on support 0 1

the inflation persistence of staggered contracts one of the criticisms routinely advanced against models with staggered contracts is their inability to generate inflation persistence this paper finds that staggered contracts a la taylor are in fact capable of reproducing the inflation persistence implied by u s data following fuhrer and moore i capture the moments that the model needs to replicate by using the correlograms from a small vector autoregression var i estimate the contract parameters using the method of maximum likelihood the correlogram of inflation for the contract model is very close to the correlogram from the var by the same metric taylor contracts fare poorly in reproducing the comovements of inflation and output

sticky price models of the business cycle can the contract multiplier solve the persistence problem we construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations these fluctuations include persistent movements in output along with the other defining features of business cycles like volatile investment and smooth consumption we assume that prices are exogenously sticky for a short time persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so we find that for a wide range of parameter values the amount of endogenous stickiness is small thus we find that in a standard quantitative model staggered price setting alone does not generate business cycle fluctuations

low inflation pass through and the pricing power of firms abstract recently there has been a significant decline in the degree to which firms pass through changes in costs to prices a decline that is frequently characterized as a reduction in the pricing power of firms the decline appears to be associated with the decline in inflation in many countries the decline has important implications for monetary policy because it affects both forecasts of inflation and the effects of changes in monetary policy on inflation some have argued that the decline in pricing power helped to keep inflation low in the face of apparently strong demand pressures in the united states in the late 1990s this paper puts forth the view that the decline in pass through or pricing power is due to the low inflation environment that has recently been achieved in many countries first a microeconomic model of price setting is used to show that lower pass through is caused by lower perceived persistence of cost changes evidence is then presented showing that inflation is positively correlated with persistence of inflation suggesting that the low inflation itself has caused the low pass through an economy wide model consistent with the micromodel is then presented to illustrate how such changes in pricing power affect output and inflation dynamics in favorable ways but can disappear quickly if monetary policy and expectations change

optimal horizons for inflation targeting abstract in this paper we investigate the problem of selecting an optimal horizon for inflation targeting in the united kingdom since there are two key ways of thinking about an optimal horizon we look at optimal horizons for both of these interpretations in addition to see whether our results are robust in the face of model uncertainty we compute optimal horizons for two different models with divergent structural and dynamic characteristics

exchange rate management viewed as tax policies abstract the paper develops an analytical framework which demonstrates that along the lines of the celebrated lerner symmetry theorem the various forms of exchange rate management are equivalent to corresponding tax policies to highlight the salient issues we consider two specific categories of exchange rate policies the first is a dual exchange rate regime which separates exchange rates for commercial and for financial transactions and the second is a unified exchange rate system in which the country unilaterally pegs its exchange rate at the same rate for all transactions we show that the dual exchange rate policies can be usefully cast as distortionary taxes on international borrowing and unified pegged exchange rate policies can be usefully cast as lump sum tax cum subsidy policies the equivalence between the various characteristics of exchange rate management and tax management suggests that exchange rate analysis could be usefully incorporated into the broader framework of the analysis of fiscal policies a two country model of the world economy is used to demonstrate the international transmission mechanism of these policies

dual exchange rate systems and capital controls an investigation abstract the welfare aspects of dual exchange rate systems are analyzed in this paper the requirement that domestic financial transactions with the rest of the world be undertaken at a special foreign exchange rate is found to be equivalent to levying a tariff on this class of international transactions hence a dual exchange rate system and capital controls are shown to be essentially identical in light of the above statements the dual exchange rate system should be regarded as a form of commercial policy and be evaluated in this context by applying the applicable standard real trade theorems

employer search training and vacancy duration we develop a model of optimal employer search strategy when information about match quality is endogenous the model is tested using four data sets two of which have not previously been used as theory predicts we find that when filling positions requiring more training employers search more intensively and extensively employers also search more extensively when hiring workers with more education and with prior experience these findings provide strong evidence of systematic variation in search strategies based on the characteristics of the positions and job applicants factors that influence employer search also affect the duration of a vacancy

inflation output variance trade offs and optimal monetary policy the author estimates the inflation output gap variance trade off faced by monetary policymakers in the united states for policymakers who care about deviations of inflation around target and output around potential the estimated trade off represents the optimal policy frontier given the structure of the economy policymakers can do no better than to attain weighted variances of inflation and output that lie on the frontier the author finds that the variance trade off becomes quite severe when the standard deviation of inflation or output drops much below 2 percent this suggests that approximately balanced responses to policy goals are consistent with reasonable preferences over inflation and output variability copyright 1997 by ohio state university press

persistent wage dispersion and involuntary unemployment it is costly for firms offers to workers to be turned down both because firms must make additional offers and making offers is costly and because capital is underused or unused provided that workers apply to at least two firms for jobs there will be wage dispersion in equilibrium and some workers will randomly fail to receive any wage offers firms in the same industry with access to the same technology may nevertheless choose different levels of capital intensity firms using capital intensive technologies will pay higher wages

gender and the consulting academic economist we surveyed academic economists on their experiences and perceptions of legal consulting nearly two thirds have consulting experience and 40 have consulted within the last 5 years base hourly rates average 244 with a median of 200 women are less likely than men to have served as consultants and charge lower rates than comparable men but there are few differences by gender in willingness to consult women report substantially more negative bias and are less likely to consult in complex cases or to have a high profile role in litigation jel j44 j71 k41

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

real exchange rate misalignment and redistribution abstract developing countries frequently maintain an overvalued nominal exchange rate resulting in real exchange rate misalignment to finance import demand at the overvalued exchange rate countries have to raise the level of income taxation or they have to resort to monetary finance this paper explains nominal and implicitly real exchange rate misalignment as the outcome of the political process more specifically the paper explains the misalignment of an import exchange rate relative to a market exchange rate used for exports voters differ in their ownership of a single factor of production real exchange rate overvaluation results if the median voter spends a relatively large share of his income on the importable good the political economy of explicit and implicit import subsidies is first analyzed in a real model which is then extended to include money holdings and exchange rate policy

inflation targeting some extensions previous analyses of the implementation of inflation targeting are extended to monetary policy responses to different shocks consequences of model uncertainty and effects of interest rate smoothing and stabilization model uncertainty output stabilization and interest rate stabilization or smoothing all call for a more gradual adjustment of the conditional inflation forecast toward the inflation target the conditional inflation forecast is the natural intermediate target during inflation targeting the optimal way of reacting to shocks is hence to check how they affect the inflation forecast and then take the appropriate action jel classification e42 e52 e58

inflation persistence and robust monetary policy design this paper examines the performance of optimised interest rate rules when there is uncertainty about a key determinant of the monetary transmission mechanism namely the degree of persistence characterising the inflation process the paper focuses on the euro area and utilises two variants of an estimated small scale macroeconomic model featuring distinct types of staggered contracts specifications which induce quite different degrees of inflation persistence the paper shows that a cautious monetary policy maker is well advised to design and implement interest rate policies under the assumption that inflation persistence is high when there is considerable uncertainty about the prevailing degree of inflation persistence such policies are characterised by a relatively aggressive response to inflation developments and exhibit a substantial degree of inertia

a small estimated euro area model with rational expectations and nominal rigidities abstract we estimate a small model of the euro area to be used for evaluating alternative monetary policy strategies starting with the relationship between output and inflation we compare the fit of the nominal wage contracting model due to taylor j political econom 88 1980 1 and the relative real wage contracting model proposed by buiter and jewitt the manchester school 49 1981 211 reprinted in buiter ed macroeconomic theory and stabilization policy manchester university press manchester 1989 and estimated with u s data by fuhrer and moore quart j econom 110 1995 127 while fuhrer and moore reject nominal contracts in favor of relative contracts which induce more inflation persistence we find that both specifications fit euro area data reasonably well when considering france germany and italy separately however we find that nominal contracts fit german data better while the relative contracting model does well with respect to formerly high inflation countries such as france and italy we close the model by estimating an aggregate demand relationship and investigate the implications of nominal versus relative contracts for the inflation output variability tradeoff when monetary policy follows taylor s rule

the optimal perception of inflation persistence is zero this study shows that in an economy with inflation persistence it is always welfare improving for a central bank that operates under discretion to behave as if there were no inflation persistence under reasonable assumptions about inflation persistence all of the inefficiency associated with discretionary policymaking is then removed

monetary policy analysis with potentially misspecified models abstract the paper proposes a novel method for conducting policy analysis with potentially misspecified dynamic stochastic general equilibrium dsge models and applies it to a new keynesian dsge model along the lines of christiano eichenbaum and evans jpe 2005 and smets and wouters jeea 2003 we first quantify the degree of model misspecification and then illustrate its implications for the performance of different interest rate feedback rules we find that many of the prescriptions derived from the dsge model are robust to model misspecification jel classification c32 key words bayesian analysis dsge models model misspecification 1 introduction the quantitative evaluation of monetary policy rules plays an important role in the design of stabilization policies much of the recent debate about optimal monetary policy rules has been carried out with new keynesian dynamic stochastic general equilibrium dsge models see woodford 2003 dsge models have the advantage that one can explicitly assess the effect of policy regime changes on expectation formation and decision rules of private agents yet until recently these models were scarcely used by central banks because they were perceived as being inferior to less structural model in terms of fit recent work by christiano eichenbaum and evans 2005 and smets and wouters 2003 has changed this perception these papers show that the fit of large scale new keynesian dsge models is comparable to that of more heavily parameterized models as a consequence a number of central banks have begun to show interest in these models as tools for quantitative policy analysis despite the success in improving the empirical performance of dsge models misspecification remains a concern as shown in del negro schorfheide smets and wouters 2004 accounting for misspecification and model uncertainty in general is an important aspect of the assessment of monetary policies after all it has long been recognized that model and parameter uncertainty affects optimal policies e g brainard 1967 chow 1975 and craine 1979 1 this paper proposes a new method for taking model misspecification into account when assessing the performance of alternative interest rate feedback rules we apply this approach to evaluate different policies in the context of a new keynesian dsge model including the estimated volcker greenspan rule a natural approach in the presence of model uncertainty is to evaluate policy rules within all the model specifications that are under consideration in choosing the best performing rule one can either follow a bayesian route assigning probabilities to models and minimizing the overall posterior expected loss alternatively one can follow a minimax strategy by adopting a policy that minimizes the worst case loss across models the literature contains numerous applications of these ideas e g mccallum 1988 levin wieland and williams 1999 2003 rudebusch 2001 2003 onatski and stock 2002 onatski and williams 2003 brock durlauf and west 2004 cogley and sargent 2005 and hansen and sargent 2005 all these papers differ with regard to the type of models included in the model set and the formulation of the decision problem that leads to the choice of a preferred policy our analysis differs from previous work with respect to the method that is used to construct a model set and assign probabilities to these models so that a bayesian calculation of posterior expected performance is possible we start from a dsge model in which monetary policy is modelled through an interest rate feedback rule the dsge model imposes cross coefficient restrictions on a vector autoregressive representation of the data while we are assuming that the data obey a vector autoregressive law of motion we allow for potential deviations from the cross coefficient restrictions at the same time we maintain the assumption that monetary policy follows the same interest rate rule as in the dsge model

hybrid inflation and price level targeting in this paper we investigate the properties of monetary regimes that combine price level and inflation targeting we look both at an optimal control and at a simple rule characterisation of these regimes we derive numerical results by modelling the economy as a small scale open economy re model calibrated on uk data we conclude that 1 the relative merits of price level and inflation targeting as well as of mixes of these two depend on particular modelling and policy assumptions and 2 these merits do not always change gradually and or monotonically as we move from one regime to another

uniform commercial policy illegal trade and the real exchange rates a theoretical analysis countries on fixed exchange rates sometimes use uniform tariff cum subsidy utcs schemes as a way of achieving a real depreciation without disturbing the nominal exchange rate a potential drawback of this policy in relation to an across the board devaluation is that a utcs scheme provides incentives for illegal trade using an optimizing model with currency convertibility and illegal trade the author finds that welfare is lower under a utcs scheme than under a corresponding across the board devaluation and that in some cases the real exchange rate actually appreciates in response to an increase in the utcs rate

special exchange rates for capital account transactions the governments of developing countries are constrained in the effective implementation of domestic policy by the interlinkages of national and international financial markets domestic macroeconomic conditions are influenced by the interaction of national and world interest rates and prices and through the impact of real exchange rates on employment the domestic responses to changes in these factors are often strong and rapid this article suggests that dual rates can indeed be used successfully as a strictly transitory policy to offset sudden shocks in capital markets the article develops models which indicate why these dual systems are able to prevent inflationary or recessionary pressures caused by a misaligned exchange rate in the short term while free capital account rates can cut the flow of capital flight however a dual rate system cannot prevent a possibly equivalent loss of foreign reserves that will ultimately result because of the impact of the overvaluation of the commercial rate on the trade balance in the longer term a dual rate system with a misaligned commercial rate exacerbates the government s deficit ultimately real wages must be cut and real interest rates raised to generate sufficient foreign exchange to finance the external debt thus a dual rate works well if the commercial rate is maintained close to the equilibrium level

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

european inflation dynamics abstract we provide evidence on the fit of the new phillips curve npc for the euro area over the period 1970 1998 and use it as a tool to compare the characteristics of european inflation dynamics with those observed in the u s we also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs as well as that of its two main components namely labor productivity and real wages some of the findings can be summarized as follows a the npc fits euro area data very well possibly better than u s data b the degree of price stickiness implied by the estimates is substantial but in line with survey evidence and u s estimates c inflation dynamics in the euro area appear to have a stronger forward looking component i e less inertia than in the u s d labor market frictions as manifested in the behavior of the wage markup appear to have played a key role in shaping the behavior of marginal costs and consequently inflation in europe

monetary policy with uncertain parameters this thesis contains four chapters each of which examines different aspects of the uncertainty facing monetary policymakers monetary policy and market interest rates investigates how interest rates set on financial markets respond to policy actions taken by the monetary authorities the reaction of market rates is shown to depend crucially on market participants interpretation of the factors underlying the policy move these theoretical predictions find support in an empirical analysis of the u s financial markets predicting monetary policy using federal funds futures prices examines how prices of federal funds futures contracts can be used to predict policy moves by the federal reserve although the futures prices exhibit systematic variation across trading days and calendar months they are shown to be fairly successful in predicting the federal funds rate target that will prevailafter the next meeting of the federal open market committee from 1994 to 1998 monetary policy with uncertain parameters examines the effects of parameter uncertainty on the optimal monetary policy strategy under certain parameter configurations increasing uncertainty is shown to lead to more aggressive policy in contrast to the accepted wisdom should central banks be more aggressive examines why a certain class of monetary policy models leads to more aggressive policy prescriptions than what is observed in reality these counterfactual results are shown to be due to model restrictions rather than central banks being too cautious in their policy behavior an unrestricted model taking the dynamics of the economy and multiplicative parameter uncertainty into account leads to optimal policy prescriptions which are very close to observed federal reserve behavior

real transfers in fixed exchange rate systems and the international adjustment mechanism abstract fixed exchange rates can be maintained by different types of stabilization schemes this paper takes a look at some alternative institutional settings and shows that there is an inherent redistribution mechanism in some of them that will influence the world allocation of consumption an examination of the global adjustment to monetary disturbances illustrates some interesting implications of the institutional differences between alternative systems the results suggest that the description of the international adjustment mechanism under fixed exchange rates given by the monetary approach to the balance of payments is valid only under quite restrictive assumptions

inflation persistence and monetary policy a simple result abstract this note explores the interaction between monetary policy and structural inflation persistence in the context of a new keynesian inflation model we solve the monetary policy problem under discretion and find that optimal monetary policy is a function of the relative weight on the output gap in the welfare theoretic stabilization objective the responsiveness of inflation to fluctuations in the output and the perceived degree of inflation persistence within our simple framework we find that underestimating inflation persistence always reduces inflation variability

does trade openness matter for aggregate instability abstract this paper presents a cash in advance model of a small open economy and shows that whether an inflation targeting interest rate rule introduces aggregate instability depends in general on the degree of openness to international trade this result emerges regardless of whether prices are sticky or flexible in a closed economy as the monetary authority responds to movements in inflation the resulting changes in interest rates affect aggregate consumption through an intertemporal substitution effect and an inflation tax effect in a small open economy this policy also induces changes in the terms of trade which depending on the degree of openness can generate counteracting effects on consumption as a consequence the implications of interest rate rules on macroeconomic stability in an open economy differ from those in a closed economy

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
