when is stabilization expansionary evidence from high inflation countries which stabilize from high inflation here defined as an annual rate above 40 usually have output expansions in the first and subsequent years of stabilization these expansions occur in both exchange rate based and money based stabilizations the paper reaches these conclusions after examining a sample of all 28 episodes in the international data that meet a pre defined criterion for stabilization from high inflation the results do not change with alternative growth and stabilization definitions the paper documents similar expansionary stabilizations in historical data and in the recent experience of the former communist economies expansionary stabilizations may be an indirect confirmation of recent theories of political economy that predict that stabilization will not occur until the gains are very large william easterly

the economics of exchange rate regimes a review essay the exchange rate regime issue has taken centre stage in discussions of international economic policy much of the profession appears to have been converted to the hypothesis of the vanishing middle regime for countries well integrated into world capital markets there is little if any middle ground between floating exchange rates and monetary unification this paper considers the exchange rate regime issue in the context of recent books on the subject by w max corden and morris goldstein both authors prescribe managed floating exchange rates supplemented with inflation targeting for emerging market economies under managed floating and with a credible monetary policy the public finances in order and strengthened debt management and prudential regulation the exchange rate is free to act as a market gauge for assessing policies and as a mode of conflict resolution both authors also argue however that no exchange rate regime is a holy grail ultimately a credible exchange rate regime depends upon the trust evoked by governments there is no exchange rate regime whether of the managed floating or hard fix variety that can eradicate a history of failed stabilisation attempts

exchange rate policy for developing countries according to the imf in the mid 1970 s approximately 85 percent of developing countries had pegged exchange rate arrangements since then the situation has changed drastically today most developing countries have either managed floats or flexible exchange rates argentina hong kong and a few others may persevere with their currency boards additional nations may well imitate them and movements toward common currencies a la the european union may gain strength here and there nonetheless it seems clear that the political and financial prerequisites to adopt such hard pegs are extremely stringent new attempts are the exception not the rule the question for most emerging market economies is no longer to float or not to float but how to float in this note we review some key issues in defining the right answer to this question

inflation stabilization the experience of israel argentina brazil bolivia and mexico rampant inflation is a major economic problem in many of the less developed countries two out of three attempts to stabilize these economies fail inflation stabilization provides a valuable description and a critical analysis of the disinflation programs introduced in argentina bolivia brazil and israel in 1985 86 and discusses the possibility of such a program in mexico it documents the initial steps in stabilization as well as the reasons for failure as architects of the programs several of the authors are in key positions to assess which aspects were critical in getting the programs accepted and where to look for difficulties and failures in israel inflation was halted without recession the challenge to policy makers today is in shifting from stabilization to the revival of sustained growth this experience is described fully by michael bruno and sylvia piterman who examine the critical issue of exchange rates and by alex cukierman who uses modeling to analyze the interaction of money wages prices and activity under rational expectations that take the government s policy objectives into account endemic inflation and a sudden increase in external debt burden argentina s economy raising the wider issues of high inflation economies and stabilization that are discussed in the chapter by jose luis machinea and that by guido di tella and alfredo canavese eduardo modiano and mario simonsen take up issues of wages in brazil particularly the problem of finding an equitable way to deal with a wage freeze simonsen develops an ambitious game theoretic rationalization of incomes policy as a coordinating device for imperfectly competitive economies bolivia did reach hyperinflation price increases of more than 50 percent each month before stabilizing juan antonio morales shows how stabilizing the exchange rate in an economy where all pricing was already geared to the dollar achieved stabilization without a wage or price freeze and francisco gil diaz asks whether an incomes policy based program could work to control ever increasing inflation in mexico michael bruno is governor of the bank of israel guido di tella is a fellow of st anthony s college a professor at the di tella institute in buenos aires and a member of parliament in argentina stanley fischer is vice president of development economics and chief economist at the world bank rudiger dornbusch is ford international professor of economics at mit

equilibrium unemployment dynamics the global dynamics of pissarides 1990 equilibrium model of aggregate unemployment are studied in the case of increasing returns to scale in production and constant returns to scale in the matching process an equilibrium is a dynamic path for the aggregate number of matches generated by best response search and recruiting investment decisions under rational expectations necessary and sufficient conditions for multiple equilibria including limit cycles are derived and illustrative examples are computed the application of saddle loop bifurcation theory is a novel feature of the analysis since one equilibrium pareto dominates all the others a macroeconomic coordination problem exists

exchange rate regimes banking and the non tradable sector abstract this paper presents a small open economy two good version of the diamond and dybvig model with cash constraints to analyze the implications on banking of different exchange rate regimes and monetary policies i show that fixed exchange rates with a central bank providing liquidity in local currency imply pareto efficiency with conditions for a run equilibrium stronger than in the literature in a flexible exchange rate regime multiple equilibria may not be eliminated in particular for very a expansive monetary policy there exists an equilibrium where a fraction of patient consumers purchases dollars in the interim period which constitutes a partial currency run a dollarized banking system without international short run credit may also implement the efficient allocation under certain conditions

inflation targeting in emerging market and transition economies lessons after a decade abstract starting in the early 1990s several emerging market and transition economies adopted inflation targeting it in this paper we discuss a number of issues that arise in this context a the definition of it b the role of preconditions for it c the use of intermediate exchange rate targets and d the specification of inflation targets our overall conclusion is that suitably modified it is a useful policy strategy for emes

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

credibility of policies versus credibility of policymakers standard models of policy credibility defined as the expectation that an announced policy will be carried out emphasize the preferences of the policymaker and the role of tough policies in signaling toughness and raising credibility whether a policy is carried out however will also reflect the state of the economy we present a model in which a policymaker maintains a fixed parity in good times but devalues if the unemployment rate gets too high our main conclusion is that if there is persistence in unemployment observing a tough policy in a given period may lower rather than raise the credibility of a no devaluation pledge in subsequent periods we test this implication on ems interest rates and find support for our hypothesis

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

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

the historical fertility transition a guide for economists the historical fertility transition is the process by which much of europe and north america went from high to low fertility in the nineteenth and early twentieth centuries this transformation is central to recent accounts of long run economic growth prior to the transition women bore as many as eight children each and the elasticity of fertility with respect to incomes was positive today many women have no children at all and the elasticity of fertility with respect to incomes is zero or even negative this paper discusses the large literature on the historical fertility transition focusing on what we do and do not know about the process i stress some possible misunderstandings of the demographic literature and discuss an agenda for future work jel i12 j13 n30

balance of payments crises in a cash in advance economy the author shows that a flexible prices sidrauski type model with a cash in advance constraint is capable of depicting some of the phenomena associated with a balance of payments crisis like the onesrecently observed in argentina and mexico current accounts deficits and appreciation of the real exchange rat e it is also shown that these phenomena become exacerbated as the rate of devaluation before the crisis occurs becomes smaller copyright 1987 by ohio state university press

fiscal consequences for mexico of adopting the dollar dollarization implies a reduction in the menu of assets available to the government and to the private sector in managing risk whatever the gains from dollarization the costs of reducing the asset menu need to be weighed against them this paper presents models one a simple generalization of a well known model of tax smoothing by ba1ao in which these costs are explicit along the way it suggests that there is likely to be no reduction in interest costs to the government from dollarization recently economists have been paying increasing attention to a dynamic general equilibrium approach to the theory of the price level that is often called the fiscal theory of the price level or ftpl this way of thinking emphasizes the role of fiscal and monetary policy in determining the risk and return properties of government liabilities it is particularly useful in analyzing proposals for large scale institutional changes that imply shifts in monetary and fiscal policies when dollarization is considered from this perspective some disadvantages are brought to light that may not be so apparent from other points of view section 1 below lays out the main ideas of ftpl section 2 displays a model that extends an earlier one of barro s to argue that optimal fiscal policy will use surprise inflation to achieve lower deadweight tax loss than would otherwise be possible section 3 considers the composition of government liabilities along the lines of the theory of corporate finance asking if dollarization will reduce the cost of funds section 4 presents annual estimates of the unanticipated returns to holders of u s government debt to show that these are substantial and are to some extent timed to match legitimate periods of fiscal stress as the optimality theory of section 2 would suggest section s discusses the lendel of last resort function and its connection to these fiscal issues section 6 briefly discusses some alternatives to pure dollarization in our concluding section 7 we sum up finding much to worry about in the prospect of dollarization

unemployment and market size without strong empirical support labour market matching models typically assume constant returns to scale in matching we construct a tractable equilibrium random matching model with a general matching technology introducing market size effects the job finding rate varies with unemployment stable steady states may occur in regions of increasing or decreasing returns and multiple equilibria are welfare ranked by market size while the standard model relies on high frequency shocks to the steady state to explain the co movement of unemployment and job finding locally decreasing returns in matching generate plausible adjustment dynamics and slower convergence lastly an extension of the hosios condition internalises search externalities

learning under fear of floating in recent years a large fraction of economies overcame the fear of floating we study a model that describes the policy of a central bank uncertain about whether currency depreciations cause output to expand textbook model or contract balance sheet model we conclude that the movement away from fear of floating may not be explained by bayesian or robust policies when the private sector anticipates the central bank s policy and endogenously determines the model central banks may fall in a learning trap an increase in financial volatility provides an escape to such trap that replicates patterns in the data

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

strict dollarization and economic performance an empirical investigation in this paper we analyze the macroeconomic record of strictly dollarized economies in particular we investigate whether dollarized countries have historically exhibited faster growth and lower volatility than countries with a domestic currency we analyze this issue by using a treatment regression analysis that estimates jointly the probability of being a dollarized country and outcome equations our analysis indicates that the probability of being a dollarized country depends on regional geographical political and structural variables our results also suggest that gdp per capita growth has not been statistically different in dollarized and in non dollarized countries we also find that volatility has been significantly higher in dollarized than in non dollarized economies these results are robust to the estimation technique and to the sample used

equilibrium models displaying endogenous fluctuations and chaos abstract this paper surveys current developments in dynamic general equilibrium theory concerned with conditions under which endogenous fluctuations are possible existing contributions are divided into two classes the larger one consists of models with a unique perfect foresight equilibrium while the second includes models where equilibrium is indeterminate and the set of equilibria involving endogenous fluctuations includes sunspots equilibria while the two classes of models involve oscillations of different natures and with different policy implications we show that both are consistent with optimizing behavior and competitive equilibrium

inflation targeting in latin america toward a monetary union this paper examines how monetary policy decisions in brazil regarding short term interest rates have affected the term structure of interest rates we apply an event study methodology in two distinct periods between january 2000 and august 2003 right after the implementation of the inflation targeting in brazil and between september 2003 and july 2008 the main results are 1 the surprise effects have decreased 2 the explanation power has increased in the second period indicating enhancement of monetary policy 3 market participants adjust their expectations with greater advance 4 the surprise effects of decisions on short term rates on the term structure of interest rates are now close to those found in the usa and germany but higher to those found in the uk and italy therefore the results indicate that fixed income market expectations are better adjusted to the central bank anti inflationary policy

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

macroeconomic effects of imf sponsored programs in latin america output costs program recidivism and the vicious cycle of failed stabilizations we investigate the effects of imf stabilization programs and the reasons behind the unusually high imf activity and relatively low program completion rates in latin america we base our tests on a panel and distinguish between imf program approvals and completion we find that latin america has higher output costs of imf programs especially when completed no improvement in the current account and a much higher likelihood of program failure and recidivism than other regions the common finding that entering into an imf supported program incurs real short run costs on the economy is entirely driven by the experiences in latin america

the importance of the exchange rate regime in limiting current account imbalances in sub saharan african countries abstract one of the major current concerns of economic policy in developing countries is the choice of the appropriate exchange rate regime to consolidate and accelerate the pace of economic growth this paper aims to investigate whether the choice of a country s exchange rate regime may affect current account imbalances for sub saharan african economies to this end we first use bayesian model averaging bma supplemented by the general to specific gets method to address concerns about model uncertainty and identify the key determinants fundamentals of external balances then estimating current account imbalances over the period 1980 2012 we show that flexible exchange rate regimes are more effective in preventing such disequilibria consequently candidates for membership of monetary unions should discuss widely the possible adjustment mechanisms before forming such unions one potential measure is the sharing of external risks at the regional level

when to dollarize implicit in the debate over dollarization are two very different views of the sequencing of policy measures one view is that dollarization to work smoothly and yield more benefits than costs must wait on the completion of complementary reforms the other view is that dollarization need not wait on these other reforms because the very act of dollarizing will produce the changes needed to smooth the operation of the new regime in this paper i consider these arguments as they apply to the cases of labor market reform fiscal reform and financial sector reform i conclude that neither theory nor evidence suggests that removing all scope for an independent monetary policy will necessarily accelerate the pace of reform

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

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

islam authoritarianism and female empowerment what are the linkages most islamic countries are governed by authoritarian regimes and in most islamic countries women s economic social and political rights are significantly less than those of the men of their country these well known facts provide the basis for a highly original and important analysis by m steven fish 1 fish s major contribution is his suggestion that the relationships at issue are not merely a matter of spurious correlation but rather are indicative of a deep underlying causal pattern in a sophisticated cross national quantitative analysis he shows the following 1 even controlling for many other alleged influences on countries political systems countries with a largely islamic religious tradition have significantly more autocratic governments than do non islamic countries 2 controlling for level of economic development the condition of women is significantly worse in islamic countries than in others 3 in a more limited test even when controlling for economic development and islamic tradition a low level of women s rights may produce lower levels of democracy 4 more speculatively islamic states may be more autocratic so as to repress women s rights more effectively or autocratic government may permit and even require the repression of a range of human rights including those of women

implicit bands in the yen dollar exchange rate this article attempts to identify implicit exchange rate regimes for the yen dollar exchange rate to that end we apply a sequential procedure that considers both the dynamics of exchange rates and central bank interventions to data covering the period from 1971 to 2003 our results suggest that implicit bands existed in two subperiods april december 1980 and march october 1987 the latter coinciding with the louvre accord furthermore the study of the credibility of such implicit bands indicates the high degree of confidence attributed by economic agents to the evolution of the yen dollar exchange rate within the detected implicit band rate thus lending further support to the relevance of such implicit bands

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

distinguished lecture on economics in government exchange rate regimes is the bipolar view correct the choice of appropriate exchange rate regime which for economies with access to international capital markets increasingly means a move away from the middle ground of pegged but adjustable fixed exchange rates towards the two corner regimes of either flexible exchange rates or a fixed exchange rate supported if necessary by a commitment to give up altogether an independent monetary policy lawrence h summers 2000 p 8

inflationary rigidities and orthodox stabilization policies lessons from latin america orthodox stabilization programs in latin american countries have been notoriously unsuccessful in combating inflation despite the imposition of stringent cuts in government deficits in most cases inflation came down only slowly and temporarily with concomitant declines in growth and employment the bolivian program one of the only latin american successes is contrasted with those of argentina brazil chile and mexico the problems of dealing with chronic inflation are compared with those of hyperinflationary countries and the influence of price and wage rigidities expectations and credibility is explored the study shows that fiscal restraint is a necessary but not sufficient condition for success and that sound management of nominal variables the exchange rate and money supply are also necessary the critical role of credibility is linked with price and wage rigidities in the chronic inflation countries whereas the unsuitability of hyperinflation is seen to increase the credibility of and thus the potential for successful stabilization programs

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

self fulfilling optimism in a trade friction model of the business cycle models of economic activity with frictions in coordinating trading have been shown to be capable of generating multiple steady states peter diamond 1982 is the pioneering work see my 1987a paper for a general discussion less work has been done on out of steady state dynamics in such models which would enable us to examine what sort of fluctuations these models may generate the absence of dynamics leaves open the question of which steady state the economy will reach as well as whether the comovements of key variables resemble what is observed over the cycle in my earlier paper 1987b i presented a model combining search and aggregate demand approaches to unemployment to show how spillovers between product and labor markets could yield multiple equilibria here a highly simplified dynamic model based on this work is presented in which self fulfilling sales expectations determine to which steady state the economy converges these expectations are summarized by the asset values of firms which are producing output relative to those that are not two types of dynamic paths leading to stationary solutions can arise the first is a saddle path in addition for certain parameter values stable limit cycles emerge interestingly over this cycle asset values of firms which one could interpret as stock market values lead economic activity i model setup

the size of banking crises in credible fixed exchange rate regimes abstract since monetary policy is constrained in fixed exchange rate regimes we should observe fewer banking crises due to moral hazard in countries with credible currency pegs however three countries with seemingly credible pegs in the nineteen eighties and nineties namely china hong kong and argentina still suffered crises in their domestic banking sectors the present note illustrates that bank incentives to take on excess risk still exist in countries with currency peg credibility and that the size of that risk exposure and thus the potential for crisis may be positively related to the level of central bank foreign exchange reserves

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

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

evaluation of currency regimes the unique role of sudden stops this paper tackles two established puzzles in international macroeconomics literature the first is the lack of systematic differences in the macroeconomic performance across exchange rate regimes the second is the absence of a clear empirical relationship between macroeconomic performance and capital account liberalization we suggest that these negative findings may be due to empirical methods that fail to account for a latent economic crisis state influenced by exchange rate and capital account regimes and to allow that latent variable to influence the growth effects of policy regimes in practice we model and estimate the latent state of the economy as a crisis probability our proposed framework of analysis allows exchange rate and capital market liberalization regimes to have both a direct effect on short term growth and an indirect effect on growth that is channelled through their effects on the crisis probability the empirical decomposition of the total effect into two conflicting effects helps resolve the puzzles assaf razin and yona rubinstein

long term determinants of the demographic transition 1870 2000 abstract this paper analyzes the long term economic determinants of the demographic transition using a large panel of countries since 1870 a simple theoretical framework accounts for the possibly nonmonotonic variations of fertility in the course of economic development as predicted by unified growth theory i find that primary schooling rather than income or health related variables is the most robust determinant of the fertility transition as regards the health transition both education and income are significant determinants of mortality rates but education alone accounts for the bulk of their time variation over the twentieth century thus education can be viewed as the main long term determinant of the demographic transition

fiscal sustainability and monetary versus fiscal dominance evidence from brazil 1991 2000 under a monetary dominant md regime the primary surplus adjusts to limit debt growth permitting monetary policy to be conducted independently of fiscal financing requirements in brazil some evidence favours an md regime for 1995 1997 but not for the decade of the 1990s as a whole while fiscal adjustments of 1999 yielded a primary surplus of about 3 of gdp consistent with solvency a credible md regime would require further adjustments of the primary surplus if debt increases growth falls or interest rates rise

what has driven the great fertility decline in developing countries since 1960 several developing countries are currently experiencing a significant fertility decline however academic economists have paid little attention to this transition this paper seeks to explain the fertility transition by infant mortality urbanisation income culture and educational attainment of females and males using annual data for 92 developing countries over the period 1960 2014 external instruments are used to deal with endogeneity the results suggest that increasing per capita income improved female education and increasing secularisation have been important determinants for declining fertility in the developing world

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

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

a dynamic equilibrium model of search bargaining and money abstract this paper considers dynamic equilibria in a model with random matching strategic bargaining and money equilibrium in the bargaining game is characterized in terms of a simple differential equation when we embed this characterization into the monetary economy the model can generate outcomes such as limit cycles that never arise if one imposes a myopic nash bargaining solution as has been done in the past journal of economic literature classification numbers c78 d83 e31

macroeconomic fluctuations and bargaining abstract i study the limit rule for bilateral bargaining when agents recognize that the aggregate economy and thus the match surplus follows a finite state poisson process the rule derived in this paper is of special importance for decentralized exchange economies with bargaining two simple applications are presented to illustrate this fact the first example is a model of wage bargaining and trade externalities i show that in such situations sophisticated bargaining tends to increase the volatility of the wage bill the second example is based on the kiyotaki wright model of money i explain how equilibrium prices depend in a fundamental way on the dynamic bargaining solution

persistence and volatility of beveridge cycles this paper aims to explain the magnitude and cyclical behavior of the fluctuations in unemployment and vacancies adding demand externalities to an otherwise standard search and matching model reduces the need for exogenous shocks in explaining these fluctuations under plausible parameter values the equilibrium dynamics include a stable limit cycle that resembles the empirically observed counterclockwise cycles around the beveridge curve quantitatively these endogenous beveridge cycles can explain half of the volatility and almost all persistence of unemployment without any exogenous forces avoiding the amplification and propagation problems of the standard model
