the policy preferences of the us federal reserve in this paper we model and explain us macroeconomic outcomes subject to the discipline that monetary policy is set optimally exploiting the restrictions that come from optimal policymaking we estimate the parameters in the federal reserve s policy objective function together with the parameters in its optimization constraints for the period following volcker s appointment as chairman we estimate the implicit inflation target to be around 1 4 and show that policymakers assigned a significant weight to interest rate smoothing we show that the estimated optimal policy provides a good description of us data for the 1980s and 1990s

how should control theory be used to calculate a time consistent government policy we study different solutions to a simple one dimensional linear quadratic game with a large number of private agents and a government a time consistent solution is defined as a solution to the hamilton jacobi bellman equation i e as a policy for which the government has noprecommitment capability this solution is compared to a policy where the government has an instantaneous pre commitment i e an equilibrium in which the government has a period by period leadership in both cases we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature

when are fixed exchange rates really fixed abstract this paper analyzes the sustainability of fixed exchange rates by extending the time inconsistency framework to a fully dynamic context in which the level of a state variable in this case debt determines the payoffs available to the government at each point in time the model yields the following results if debt is sufficiently low there is an equilibrium in which the government does not devalue for an intermediate range of debt levels the government devalues in response to an attack but not otherwise so that self fulfilling attacks can occur finally for yet another debt range there can also be sunspot equilibria in which an attack and the corresponding devaluation occurs with positive probability

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

solution of macromodels with hansen sargent robust policies some extensions abstract we summarize some methods useful in formulating and solving hansen sargent robust control problems and suggest extensions to discretion and simple rules matlab octave and gauss software is provided we illustrate these extensions with applications to the term structure of interest rates the time inconsistency of optimal monetary policy the effects of expectations on the variances of inflation and output and on whether central banks should make their forecasts public

living and dying with hard pegs the rise and fall of argentina s currency board the rise and fall of argentina s currency board shows the extent to which the advantages of hard pegs have been overstated the currency board did provide nominal stability and boosted financial intermediation at the cost of endogenous financial dollarization but did not foster monetary or fiscal discipline the failure to adequately address the currency growth debt trap into which argentina fell at the end of the 1990s precipitated a run on the currency and the banks followed by the abandonment of the currency board and a sovereign debt default the crisis can be best interpreted as a bad outcome of a high stakes strategy to overcome a weak currency problem to increase the credibility of the hard peg the government raised its exit costs which deepened the crisis once exit could no longer be avoided but some alternative exit strategies would have been less destructive than the one adopted

learning expectations formation and the pitfalls of optimal control monetary policy this paper examines the robustness characteristics of optimal control policies derived under the assumption of rational expectations to alternative models of expectations we assume that agents have imperfect knowledge about the precise structure of the economy and form expectations using a forecasting model that they continuously update based on incoming data we flnd that the optimal control policy derived under the assumption of rational expectations can perform poorly when expectations deviate modestly from rational expectations we then show that the optimal control policy can be made more robust by deemphasizing the stabilization of real economic activity and interest rates relative to in ation in the central bank loss function that is robustness to learning provides an incentive to employ a conservative central banker we then examine two types of simple monetary policy rules from the literature that have been found to be robust to model misspeciflcation in other contexts we flnd that these policies are robust to empirically plausible parameterizations of the learning models and perform about as well or better than optimal control policies

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

fiscal deficits and inflation abstract macroeconomic theory postulates that persistent fiscal deficits are inflationary yet empirical research has had limited success in uncovering this relationship this paper reexamines the issue in light of broader data and a new modeling approach that incorporates two key features of the theory unlike previous studies we model inflation as non linearly related to fiscal deficits through the inflation tax base and estimate this relationship as intrinsically dynamic using panel techniques that explicitly distinguish between short and long run effects of fiscal deficits results spanning 107 countries over 1960 2001 show a strong positive association between deficits and inflation among high inflation and developing country groups but not among low inflation advanced economies

spurious welfare reversals in international business cycle models several papers have documented spurious welfare reversals incompletemarkets economy produces a higher level of welfare than the completemarkets economy this paper first demonstrates how conventional linearization can generate approximation errors that can result in welfare reversals using a two country production economy we argue that spurious welfare reversals are not only possible but also plausible under reasonable values for model parameters this paper then proposes an approximation method that modifies the conventional linearization by a bias correction this method can be easily implemented and approximates welfare as accurately as a second order perturbation method

openness imperfect exchange rate pass through and monetary policy abstract this paper analyses the implications of imperfect exchange rate pass through for optimal monetary policy in a linearised open economy dynamic general equilibrium model calibrated to euro area data imperfect exchange rate pass through is modelled by assuming sticky import price behaviour the degree of domestic and import price stickiness is estimated by reproducing the empirical identified impulse response of a monetary policy and exchange rate shock conditional on the response of output net trade and the exchange rate it is shown that a central bank that wants to minimise the resource costs of staggered price setting will aim at minimising a weighted average of domestic and import price inflation

dependency disarticulation and denominator effects another look at foreign capital penetration less developed countries desparately need capital to develop but countries dependent on foreign capital face slower economic growth higher income inequality and possibly impaired domestic capital formation these conclusions emerge from a reassessment of glenn firebaugh s broad critique of capital dependency research which exposed an important error in earlier studies the solution charts new theoreticall ground by factoring dependency effects into the differential productivity of foreign and domestic investment and the negative externalities from foreign capital penetration the revised formulation is applied to cross national analyses of economic growth decapitalization and income inequality the findings consistently support capital dependency theory

exchange rate regime durability and performance in developing versus advanced economies abstract drawing on new data and advances in exchange rate regimes classification we find that countries appear to benefit by having increasingly flexible exchange rate systems as they become richer and more financially developed for developing countries with little exposure to international capital markets pegs are notable for their durability and relatively low inflation in contrast for advanced economies floats are distinctly more durable and also appear to be associated with higher growth for emerging markets our results parallel the baxter and stockman classic exchange regime neutrality result though pegs are the least durable and expose countries to higher risk of crisis

price level versus inflation targeting abstract this paper shows that price level targeting outperforms inflation targeting in the standard new keynesian model under the assumption that the central bank is forced to operate in an environment characterized by discretion in the benchmark case with no persistence in the shocks the commitment solution can be fully replicated intuitively price level targeting introduces history dependence and a stationary level of prices both of which are prominent features of the commitment solution

temporary stabilization predetermined exchange rates the paper analyzes the impact of a stabilization policy based on a temporary reduction in the rate of devaluation against a background in which a constant rate of devaluation has no real effects it is shown that the temporary policy does and furthermore that the real effects tend to become bigger in absolute value as the horizon of the temporary policy is shortened the central discussion is carried out in terms of a one good cash in advance model with perfect capital mobility and ramsey type consumers results are extended to account for home goods and variable velocity the roles of capital mobility and banking liberalization are briefly 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

political cycles and exchange rate based stabilization fixed exchange rates implemented to increase credibility and attract foreign investment or as an alternative approach to stabilization in high inflation economies have been shown to be successful in expanding economic activity and correcting inflation in the short term but often lead to undesirable outcomes in the medium to long term although there is a wealth of literature documenting the boom bust cycles associated with the adoption of a nominal anchor no adequate explanation has been proffered as to governments repeatedly choosing policies that are self defeating the authors address this question with a political economy explanation based on the notion of a self interested government for which short term stabilization is attractive in the face of incentives posed by the electoral cycle if the election coincides with the boom phase of an exchange rate based stabilization incumbent governments increase the likelihood of gaining reelection and the bust phase will develop if at all only after the contest the authors thus suggest a modified version of the traditional political business cycle from the standpoint of a self interested office seeking government exchange rate based stabilizations can make good political sense empirical results based on an analysis of eighteen latin american countries from 1970 to 1999 support the insights of the argument movements towards a more fixed exchange rate are greater than three times more likely in a preelection period than in other stages of the electoral cycle

disinflation and fiscal reform a neoclassical perspective abstract many latin american countries engaged in disinflation programs based on both exchange rate management and fiscal reforms in most of the cases part of the fiscal reform was not implemented and the program had to be abandoned the aftermath of these programs is not encouraging in this paper we show that if the reform process is uncertain and inflation has welfare costs the optimal exchange rate policy indeed implies the initiation of a disinflation program at the announcement of the fiscal reform even if it implies the possibility of a balance of payments crisis finally we show that it is optimal to engage in a sequence of stabilization programs until one of them is successful

temporary stabilization policy abstract the effects of a temporary slowdown in the rate of expansion of money supply are studied under ramsey lucas and money superneutrality assumptions it is shown that such a policy expands consumption and leads to capital decumulation and current account deficits in the short run the model is a benchmark case in which temporary policy is always detrimental to welfare connection with the policy credibility issue is briefly discussed

excessive deficits sense and nonsense in the treaty of maastricht maastricht s fiscal rules willem buiter giancarlo corsetti and nouriel roubini the maastricht treaty on economic and monetary union in the ec has specified limits on both government debt and fiscal deficits satisfying these criteria is necessary for getting into emu once inside violating these limits will also incur penalties the fiscal requirements especially the debt criterion are much tougher than is required to ensure public sector solvency trying to attain these targets will force the ec initially into substantial deflation and recession failure to correct for real growth inflation and the business cycle makes the nominal deficit a poor basis for any policy or target ambiguity about how fiscal targets will in fact be interpreted might provide a way out but cannot today be relied upon to do so supranational fiscal rules are sometimes claimed to be justified by externalities in national fiscal policies we find this justification wanting both in theory and empirically a better case might be built on the imposition of external commitments to offset domestic political distortions that systematically induce excessive deficits even so we conclude that the fiscal convergence criteria on balance are harmful and should be disregarded or applied very loosely to avoid the risk of serious fiscal overkill

international coordination of fiscal policy in limiting economies we examine the limiting behavior of cooperative and noncooperative fiscal policies as countries market power goes to zero we show that these policies converge if countries raise revenues through lump sum taxation however if there are unremovable domestic distortions such as distorting taxes there can be gains to coordination even when a single country s policy cannot affect world prices these results differ from the received wisdom in the optimal tariff literature the key distinction is that contrary to the tariff literature the spending decisions of governments are explicitly modeled

sub saharan africa s growth south south trade and the generalised balance of payments constraint using the post keynesian balance of payments constrained growth approach we investigate the recent increase in sub saharan africa ssa growth focussing on the contribution of south south trade the model is estimated by panel co integration on a sample of 20 low and lower middle income ssa countries using annual data from 1990 to 2008 and considering three partner areas ssa itself developing asia and the rest of the world the results show that in the past decade the balance of payments constraint of ssa has been relaxed this shift has occurred through different channels of transmission the other ssa countries contributed through the real growth effect developing asia through the market share effect and the rest of the world through the terms of trade effect these results help reconcile puzzling evidence on the pattern of ssa external indebtedness and provide new insights on the role of asian drivers on ssa growth as well as on the sustainability of ssa growth recovery

tight money and inflation further results abstract the sargent wallace results on inflationary effects of monetary restraint are considered in a sidrauski money growth model when the utility function is unrestricted except for separability temporary monetary tightening will eventually lead to higher inflation when the deficit is fixed only if the elasticity of money demand with respect to the money growth rate is less than unity it is also shown that for inflation to rise immediately further requires the elasticity with respect to the nominal interest rate to be no less than unity

fiscal sustainability and dollarization the case of ecuador abstractthis article tries to disentangle the dynamic relationships between fiscal variables and economic activity in a small emerging economy characterized by full dollarization namely ecuador we find that fiscal policy in ecuador seems to be sustainable explained by its policy of debt payment through oil revenues rather than by a fiscal discipline that dollarization is supposed to encourage the non oil tax revenues variable is a purely adjusting variable this result suggests that in a dollarized country that cannot benefit from the seignorage revenues the reliance on volatile oil revenues and on smoothing tax revenues leaves the economy s fiscal sustainability vulnerable

explaining the duration of exchange rate pegs abstract this paper is an empirical investigation of the duration of exchange rate pegs in 16 latin american countries and jamaica we identify factors that influence peg duration using logit analysis the real exchange rate and the level of international liquidity are significant determinants of the monthly likelihood of devaluation structural variables such as the openness of an economy and its geographical trade concentration and political variables such as changes in the executive also significantly affect the likelihood of a devaluation there is some evidence that the likelihood of a devaluation first rises and subsequently declines during the first year of a peg

price level versus inflation targeting under model uncertainty the purpose of this paper is to make a quantitative contribution to the in ation vs price level targeting debate it considers a policymaker that can set policy either through an in ation targeting rule or a price level targeting rule to minimize a quadratic loss function using the actual projection model of the bank of canada totem the paper flnds that price level targeting dominates in ation targeting signiflcantly although it can lead to much more volatile in ation than in ation targeting depending on the weight assigned to output gap stabilization in the loss function the price level targeting rule is also found to mimic the full commitment solution quite well but there is an important difierence the full commitment solution does not require stationarity in the price level the paper then analyzes the extent to which the results are sensitive to hansen and sargent 2004 model uncertainty the paper flnds the price level targeting rule to be robust its performance deteriorates slower than the in ation targeting rule and the absolute decline in performance is small in magnitude

the advantage of tying one s hands ems discipline and central bank credibility abstract it is often argued that the ems is an effective disciplinary device for inflation prone countries in europe since it forces the respective policy makers to pursue more restrictive monetary policies than they would otherwise it is not clear however why these countries should submit themselves to such discipline this paper argues that to answer this question appropriately one must consider that ems membership brings potentially large credibility gains policy makers in inflation prone countries the reason is that not only it attaches an extra penalty to inflation in terms of real appreciation but makes the public aware that the policy maker is faced with such penalty and thus helps to overcome the inefficiency stemming from the public s mistrust of the authorities

income inequality development and dependence a reconsideration we reconsider the role of foreign investment in income inequality in light of recent critiques that question the results of quantitative cross national research on foreign capital penetration we analyze an unbalanced cross national data set in which countries contribute different numbers of observations with a maximum of 88 countries and 488 observations dated from 1967 to 1994 random effects regression models that control for unmeasured country heterogeneity are used to investigate effects of foreign capital penetration on inequality measured as the gini coefficient against the background of an internal developmental model of inequality we adapt firebaugh s 1992 1996 critique of the literature on the effect of foreign investment on economic growth to the study of income inequality and find that the stock of foreign direct investment has an effect on inequality that is independent of the mechanisms identified by firebaugh we explore tsai s 1995 claim that the effect of foreign capital penetration is spurious and find that foreign stock has a significant positive effect on inequality net of region specific differences an alternative interpretation of the findings of the foreign investment inequality literature is discussed in light of the discovery of an inverted u shaped relationship between income inequality and foreign investment stock per capita we conclude that thinking on the relationship between income inequality and investment dependence should be revised in light of an investment development path relating the inflow and outflow of foreign capital to economic development

fiscal discipline and the choice of a nominal anchor in stabilization abstract the conventional wisdom is that exchange rate based stabilizations induce more fiscal discipline than money based programs the latin american experience does not support this view among the major stabilization programs implemented since 1960 the mean increase in the primary balance to gdp ratio was 3 2 percentage points under money based programs as opposed to only 0 2 percentage points under exchange rate based programs we present a model where fiscal policy is set by an optimizing but non benevolent government that replicates this stylized fact if the policy maker is impatient a money based stabilization provides more discipline and higher welfare for the representative agent than does an exchange rate based stabilization

are fiscal deficits inflationary abstract this paper applies the dynamic panel quantile regression dpqr model under the autoregressive distributional lag ardl specification and examines the deficit inflation relationship in 91 countries from 1960 to 2006 the dpqr model estimates the impact of deficits on inflation at various inflation levels and allows for a dynamic adjustment with the ardl specification the empirical results show that the fiscal deficit has a strong impact on inflation in high inflation episodes and has a weak impact in low inflation episodes the results imply that fiscal consolidation would be more effective in price stabilization the higher the inflation rate is and are consistent with the theoretical model of catao and terrones 2005

capital inflows fiscal discretion and exchange rate policy many writers have argued for the benefits of a credible fixed exchange rate a hard peg as a commitment device in an open economy but historically fixed exchange rates have often been associated with large current account deficits and episodes of over borrowing this paper develops a model of capital inflows that are linked to the exchange rate regime because of endogenous fiscal policy the key message of the paper is that a hard peg is undesirable in the absence of commitment in fiscal policy in face of a credible fixed exchange rate the fiscal authority subsidizes capital inflows the economy will engage in inefficiently high international borrowing and in welfare terms may end up worse off than under capital market autarky to eliminate the incentive to subsidize borrowing the monetary authority must follow a flexible exchange rate rule in which capital inflows lead to exchange rate appreciation if fiscal policy must be financed by money creation rather than direct taxation then a fixed exchange rate rule may cause both over borrowing and a subsequent exchange rate crisis r 2005 elsevier b v all rights reserved

the optimal inflation rate in new keynesian models should central banks raise their inflation targets in light of the zero lower bound we study the effects of positive steady state inflation in new keynesian models subject to the zero bound on interest rates we derive the utility based welfare loss function taking into account the effects of positive steady state inflation and solve for the optimal level of inflation in the model for plausible calibrations with costly but infrequent episodes at the zero lower bound the optimal inflation rate is low typically less than two percent even after considering a variety of extensions including optimal stabilization policy price indexation endogenous and statedependent price stickiness capital formation model uncertainty and downward nominal wage rigidities on the normative side price level targeting delivers large welfare gains and a very low optimal inflation rate consistent with price stability these results suggest that raising the inflation target is too blunt an instrument to efficiently reduce the severe costs of zero bound episodes

social articulation as a condition for equitable growth abstract a formal model is developed to establish the structural conditions that result in growth being progressive or regressive on the personal distribution of income these conditions include 1 intersectoral investment priorities between wage goods and luxuries and 2 the state of the levels and distribution of incomes which determines the social origin of demand for different sectors of the economy the particular combinations of investment and income structures that result in equalizing social articulation or unequalizing growth social disarticulation are derived we show empirically that the structural conditions that allowed rapid but unequalizing growth in brazil between 1968 and 1977 were those of social disarticulation

another look at the export of raw materials and economic growth recent empirical evaluations of the economic consequences of specialization in the export of raw materials have been seriously hampered by inadequate conceptualization and measurement of the central variables a scale is advanced to measure relative degree of processing of exports and it is shown that specializing in the export of goods with low levels of processing has a significant negative effect on economic growth the broader results suggest that position in the world economy is an important determinant of the economic fate of nations

exchange rate regimes in the modern era fixed floating and flaky this paper provides a selective survey of the incidence causes and consequences of a country s choice of its exchange rate regime i begin with a critical review of michael klein and jay c shambaugh s 2010 book exchange rate regimes in the modern era and then proceed to provide an alternative overview of what the economics profession knows and needs to know about exchange rate regimes while a fixed exchange rate with capital mobility is a well defined monetary regime floating is not thus it is unclear whether it is theoretically sensible to compare countries across exchange rate regimes this comparison is quite difficult to make empirically it is often hard to figure out what the exchange rate regime of a country is in practice since there are multiple conflicting regime classifications more importantly similar countries choose radically different exchange rate regimes without substantive consequences for macroeconomic outcomes like output growth and inflation that is the profession knows surprisingly little about either the causes or consequences of national choices of exchange rate regimes but since the consequences of these choices are small understanding their causes is of only academic interest jel e52 f33

inflation openness and exchange rate regimes the quest for short term commitment abstract this paper further tests romer s romer d 1993 openness and inflation theory and evidence quarterly journal of economics 58 869 903 extension of kydland and prescott s kydland f prescott e 1977 rules rather than discretion the inconsistency of optimal plans journal of political economy 85 473 491 predictions for dynamic inconsistency problems in open economies in a panel data set of developed and developing countries from 1973 to 1998 i find that openness does not play a role in restricting inflation in the short run on the other hand a fixed exchange rate regime plays a significant role the results are robust to controlling for other variables that determine inflation performing sensitivity analysis and using a de facto exchange rate regime classification

was this time different fiscal policy in commodity republics abstract we revisit the issue of fiscal procyclicality in commodity rich nations commodity republics in the nomenclature of this paper since commodity prices are plausibly a main driver of fiscal policy outcomes in these countries we focus on the behavior of fiscal variables across the commodity cycle in contrast to behavior across the output cycle which has been the main focus of earlier research on fiscal procyclicality we present evidence of reduced fiscal policy procyclicality in a number of countries our empirical results suggest that improvements in institutional quality have led to a more countercyclical fiscal policy stance in a number of countries the presence of fiscal rules also seems to have made a difference countries that use them displayed a larger shift toward fiscal counter cyclicality between the two episodes

currency boards more than a quick fix currency boards more than a quick fix once a popular colonial monetary arrangement currency boards fell into disuse as countries gained political independence but recently currency boards have made a remarkable come back this essay takes a critical look at their performance are currency boards really a panacea for achieving low inflation and high growth or do they merely provide a quick fix allowing authorities to neglect fundamental reforms and thus fail to yield lasting benefits we have three major findings first the historical track record of currency boards is sterling with few instances of speculative attacks and virtually no involuntary exits countries that did exit from currency boards did so mainly for political rather than economic reasons and such exits were usually uneventful second modern currency boards have often been instituted to gain credibility following a period of high or hyperinflation and in this regard have been remarkably successful countries with currency boards experienced lower inflation and higher if more volatile gdp growth compared to both floating regimes and simple pegs the inflation difference reflects both a lower growth rate of money supply a discipline effect and a faster growth of money demand a credibility effect the gdp growth effect is significant but may simply reflect a rebound from depressed levels third case studies reveal the successful introduction of a currency board to be far from trivial requiring lengthy legal and institutional changes as well as a broad economic and social consensus for the implied commitment moreover there are thorny issues as yet untested regarding possible exits from a currency board thus currency boards do not provide easy solutions but if introduced in the right circumstances with some built in flexibility they can be an important tool for gaining credibility and achieving macroeconomic stabilization atish r ghosh anne marie and holger c wolf

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

disarticulation and human welfare in less developed countries disarticulation refers to the juxtaposition of economic sectors with different levels of development and productivity disarticulation is hypothesized to have a negative effect on social well being net of economic development because it inhibits the spread effects generally thought to be associated with economic growth findings are in accord with this hypothesis although the relationship is complex the strongest effects of disarticulation are found among the poorest nations the concept of disarticulation opens a new and promising avenue of research that may help to resolve contradictory findings of recent research on the political economy of growth

fixed versus flexible exchange rates which provides more fiscal discipline abstract conventional wisdom holds that fixed rates provide more fiscal discipline than do flexible rates in this paper we show that this wisdom need not hold in a standard model in which fiscal policy is endogenously determined by a maximizing fiscal authority the claim that fixed rates induce more discipline stresses that sustained adoption of lax fiscal policies must eventually lead to an exhaustion of reserves and thus to a politically costly collapse of the peg hence under fixed rates bad behavior today leads to punishment tomorrow under flexible rates bad behavior has costs as well the difference is in the intertemporal distribution of these costs flexible rates allow the effects of unsound fiscal policies to manifest themselves immediately through movements in the exchange rate hence bad behavior today leads to punishment today if fiscal authorities are impatient flexible rates by forcing the costs to be paid up front provide more fiscal discipline and higher welfare for the representative private agent the recent experience of sub saharan countries supplies evidence that matches the predictions of the model

stabilization with exchange rate management stabilization programs in open economies typically consist of two stages in the first stage the rate of currency devaluation is reduced but the fiscal adjustment does not eliminate the fiscal deficit that causes growth of debt and loss of reserves making a future policy change necessary only later at a second stage is this followed by either an abandonment of exchange rate management or by a sufficiently large cut in the fiscal deficit we study how different second stage policy changes affect economic dynamics during the first stage these changes include tax increases budget cuts on traded and nontraded goods and increases in the growth rate of money

the mirage of exchange rate regimes for emerging market countries this paper argues that much of the debate on choosing an exchange rate regime misses the boat it begins by discussing the standard theory of choice between exchange rate regimes and then explores the weaknesses in this theory especially when it is applied to emerging market economies it then discusses a range of institutional traits that might predispose a country to favor either fixed or floating rates and then turns to the converse question of whether the choice of exchange rate regime may favor the development of certain desirable institutional traits the conclusion from the analysis is that the choice of exchange rate regime is likely to be of second order importance to the development of good fiscal financial and monetary institutions in producing macroeconomic success in emerging market countries this suggests that less attention should be focused on the general question whether a floating or a fixed exchange rate is preferable and more on these deeper institutional arrangements a focus on institutional reforms rather than on the exchange rate regime may encourage emerging market countries to be healthier and less prone to the crises that we have seen in recent years

solving for optimal simple rules in rational expectations models this paper presents algorithms that solve for optimal simple monetary policy rules in rational expectations models with precommitment and discretion the algorithms are applied to the models in fuhrer j money credit banking 29 1997 214 clarida et al j econ lit 37 1999 1661 and rudebusch econ j 112 2002 402 to examine the efficiency properties of operational policy rules we show that optimized taylor type rules preform well in these models but that aside from the fuhrer moore model this result is sensitive to whether the central bank can respond to current period shocks taylor type rules that are operational in the sense that they do not respond to current period information are found to be highly inefficient in the rudebusch model and in the clarida et al 1999 model

fiscal discipline and the choice of exchange rate regime conventional wisdom claims that fixed exchange rates provide more fiscal discipline than do flexible rates but the recent experiences in europe the record of sub saharan countries in the 1980s and the history of stabilization attempts in latin america cast empirical doubts on this wisdom to explore this puzzle we present a standard intertemporal model with perfect capital mobility and price flexibility in which fiscal policy is endogenously determined by a maximizing fiscal authority

do fixers perform worse than non fixers during global recessions and recoveries there is an important debate about how economies with different exchange rate regimes performed during the great recession and its ensuing recovery while economic theory suggests that economies with fixed exchange rates are more affected and recover more slowly from global shocks than economies with non fixed exchange rates the empirical evidence on the most recent global recession has been mixed this paper examines the exchange rate and economic growth nexus and assesses how this relationship is affected by the four global recessions and recoveries the world economy has experienced post bretton woods while there is no robust long term relationship between exchange rate regimes and growth there is evidence that fixers recover from global recessions at a weaker pace than non fixers
