to float or to fix evidence on the impact of exchange rate regimes on growth we study the relationship between exchange rate regimes and economic growth for a sample of 183 countries over the post bretton woods period using a new de facto classification of regimes based on the actual behavior of the relevant macroeconomic variables in contrast with previous studies we find that for developing countries less flexible exchange rate regimes are associated with slower growth as well as with greater output volatility for industrial countries regimes do not appear to have any significant impact on growth the results are robust to endogeneity corrections and a number of alternative specifications borrowed from the growth literature

real sources of european currency policy sectoral interests and european monetary integration in the thirty years before economic and monetary union was achieved european currency policies varied widely among countries and over time in this article i argue that the sectoral impact of regional exchange rate arrangements in particular their expected real effects on european trade and investment exerted a powerful influence on the course of european monetary integration the principal benefit of fixing european exchange rates was facilitation of cross border trade and investment within the european union eu the principal cost of fixed rates was the loss of national governments ability to use currency policy to improve their producers competitive position empirical results indeed indicate that a stronger and more stable currency was associated with greater importance of manufactured exports to the eu s hard currency core while depreciations were associated with an increase in the net import competition faced by the country s producers this suggests a powerful impact of real factors related to trade and investment and of private interests concerned about these factors in determining national currency policies

german dominance in the ems evidence from interest rates abstract the paper presents an empirical analysis of german dominance and asymmetries in the ems based on a dynamic system of equations explaining national money market interest rates the hypothesis of strict german dominance of the ems is rejected however there are some noticeable asymmetries in the ems germany is a relatively strong player and has been the least dependent country in the early phase of the system since 1983 german independence has diminished in contrast france throughout and italy in the early phase of the ems have been relatively weak players in the system

exchange rate behaviour under the ems regime was there any systematic change abstract most empirical studies fail to detect any systematic effects of the ems regime on the economic performance of member countries this reveals the difficulty of constructing controlled experiments which can distinguish what is due to the ems from that due to common external pressures we argue that the crucial step is to examine the exchange rates distribution since no performance improvements will appear if exchange rate behaviour does not change within the ems we find that there are changes in the third and fourth moments which imply that ems currencies have become more fragile and susceptible to shocks particularly negative shocks relative to non ems currencies

an economic model of soil conservation by introducing soil depth and soil loss into a simple model of agricultural production this paper seeks to determine when the private path of erosion differs from the socially optimal path considering the depletion of soil only and abstracting from the environmental disruption caused by erosion the paper argues that under most institutional arrangements the social and private rates of erosion are the same the paper concludes that public policy should be directed toward reducing erosion only when it leads to significant pollution externalities

fear of floating and the external effects of currency unions the introduction of the euro has considerably affected the de facto monetary policy autonomy defined as independence from monetary policy in the key currency areas in countries outside the european currency union ecu using a standard open economy framework we argue that de facto monetary policy autonomy has significantly declined for countries that dominantly trade with the ecu and slightly increased for countries that dominantly trade with the dollar zone the predictions of our model find support in the data we estimate the influence of the bundesbank s ecb s and the fed s monetary policies on various country groups the de facto monetary policy autonomy of both non euro eu members and efta countries declined with the introduction of the euro this effect was slightly stronger for the eu member countries than for efta countries as our theory predicts at the same time the de facto monetary policy autonomy of australia and new zealand vis a vis the us dollar has moderately increased

the impact of soil conservation and output diversification on farm income in central american hillside farming this article analyzes the determinants of farm income among hillside farmers participating in natural resource management projects in el salvador and honduras the farm income function was evaluated using a system of equations in which income is determined simultaneously by the farmer s decision to adopt soil conservation technologies and by the level of diversification number of agricultural activities on the farm the database used comes from surveys administered to 678 beneficiaries of these projects during 2002 the econometric results suggest that all the variables related directly to land use i e output diversification soil conservation practices and structures and the adoption of forestry systems have a positive and statistically significant association with farm income also farmers who own land enjoy higher farm incomes than those who do not the results indicate that when investing in natural resource management projects governments and multilateral development agencies should pay close attention to output diversification land tenure and human capital formation as effective instruments in increasing farm income

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

soil conservation and governmental policies in tropical areas does aid worsen the incentives for arresting erosion this paper focuses on how farmers respond with respect to the adoption of soil conservation measures to governmental agricultural policies aiming at supporting smallholders a simple micro economic framework was chosen to undertake an analysis of farmer choices among three activities farming adoption of soil conservation measures and off farm work the model shows that governments have to be cautious when designing support measures if improved resource management is a policy goal in the design of such measures attention has to be paid both to 1 the distribution in land quality and 2 the distribution in the net returns from adopting soil conservation measures

delegation in international monetary policy games abstract in this paper we show that delegation of monetary policy to an independent and more conservative central banker is an optimal policy in a multi country framework with monetary spillovers among countries even in the absence of time inconsistency credibility issues we also study the welfare implications of delegating monetary policy and extend our analysis to the case of coordination of monetary policies

on becoming more flexible exchange rate regimes in latin america and the caribbean abstract this paper examines the shift from fixed to more flexible exchange rate regimes among countries in latin america and the caribbean in contrast to most traditional approaches the one followed here recognizes that fixed rates can be and often are adjusted but argues that policy makers incur a political cost from devaluation at the same time flexible exchange rates even managed ones may be very volatile with persistent misalignment a stylized model of regime choice is developed based on the perceived losses from exchange rate misalignment incurred under fixed versus more flexible regimes the model is estimated for a sample of 24 countries over the period 1978 1992 and empirical results are quite supportive misalignments proxied by current account deficits and moderate to high rates of inflation were associated with a move to more flexible rates during 1978 1986 misalignment indicators appear to have mattered less during 1987 1992 however there appears to have been a major reduction in the perceived difficulty of managing flexible rates during this period the paper then cautions against attributing differences in economic growth between groups of countries to their exchange regime the central point here is that the endogeneity of regime choice introduces selection biases into the samples of countries with fixed and with more flexible exchange regimes

capital controls and balance of payments crises abstract the theory of balance of payments crises shows that under perfect foresight a system of fixed exchange rate is not sustainable in the presence of diverging economic policies in this paper it is shown how and why capital controls succeed in maintaining the principle of a fixed but adjustable parity both cases of a devaluation and a revaluation are considered and a condition for a parity change to be credible is presented

natural resource economics and conservation contributions of agricultural economics and agricultural economists research by agricultural economists on natural resources has been distinguished by an interdisciplinary emphasis and a dynamic perspective it has recognized technological and institutional constraints has been oriented toward solving concrete resource management and policy problems and has emphasized empirical and quantitative analysis agricultural economists have introduced methods for evaluating natural resource conservation efforts for predicting adoption of resource conservation technologies and for designing efficient and sustainable resource management policies they have identified ways of improving land management and preventing land degradation proposed reforms of institutions governing water allocation and water quality and introduced policies for balancing environmental and efficiency considerations in the management of pests biodiversity and livestock diseases their research has had substantial impacts on the formulation of resource conservation policies

the modern history of exchange rate arrangements a reinterpretation we develop a novel system of reclassifying historical exchange rate regimes one key difference between our study and previous classifications is that we employ monthly data on market determined parallel exchange rates going back to 1946 for 153 countries our approach differs from the imf official classification which we show to be only a little better than random it also differs radically from all previous attempts at historical reclassification our classification points to a rethinking of economic performance under alternative exchange rate regimes indeed the breakup of bretton woods had less impact on exchange rate regimes than is popularly believed

choosing and reneging on exchange rate regimes we use data on announced and actual exchange rate arrangements to ask which countries follow de facto regimes different from their de iure ones that is do not do what they say our results suggest that countries with poor institutional quality have difficulty in maintaining pegging and abandon it often in contrast many countries with relatively good institutions display fear of floating that is they manage more than announced perhaps to signal their differences from those countries incapable of maintaining promises of monetary stability jel f3 o1

quantitative goals for monetary policy we study empirically the macroeconomic effects of an explicit de jure quantitative goal for monetary policy quantitative goals take three forms exchange rates money growth rates and inflation targets we analyze the effects on inflation of both having a quantitative target and of hitting a declared target our empirical work uses an annual data set covering 42 countries between 1960 and 2000 and takes account of other determinants of inflation such as fiscal policy the business cycle and openness to international trade and the endogeneity of the monetary policy regime we find that both having and hitting quantitative targets for monetary policy is systematically and robustly associated with lower inflation the exact form of the monetary target matters somewhat especially for the sustainability of the monetary regime but is less important than having some quantitative target successfully achieving a quantitative monetary goal is also associated with less volatile output

credibility and disinflation in the european monetary system analysis of interest differentials in the european monetary system has suggested a widespread lack of credibility of the exchange rate mechanism in the sense that in most countries the implicit expected rate of devaluation was significant and not far short of inflation differentials vis a vis the deutschmark we present and test a model in which prices reflect expectations of exchange rate behaviour the results provide mixed evidence that price setting in countries which participated in the erm was influenced by the exchange rate discipline

political business cycles and macroeconomic credibility a survey there is clear evidence that government popularity and election performance is affected in part by economic performance suggesting that governments may manipulate the economy to political advantage simple models incorporating adaptive expectations which allowed the government to exploit this relationship were developed in the 1970s but fell out of fashion with the advent of new classical economics however modern theories of the political business cycle which are closely related to the macroeconomic policy game literature assume rational expectations and lead to forms of political business cycle driven by the existence of uncertainty of one type or another the international evidence suggests that some aspects of the theories apply although definitive conclusions are as we might expect hard to come by

the mirage of fixed exchange rates this paper discusses the profound difficulties of maintaining fixed exchange rates in a world of expanding global capital markets contrary to popular wisdom industrialized country monetary authorities easily have the resources to defend exchange parities against virtually any private speculative attack but if their commitment to use those resources lacks credibility with markets the costs to the broader economy of defending an exchange rate peg can be very high the dynamic interplay between credibility and commitment is illustrated by the 1992 swedish and british crises and the 1994 95 mexican collapse we also discuss the small number of successful fixers

delegation in a general equilibrium model of customs unions abstract a difference in the objectives of members of a customs union may be a unifying rather than a divisive force if countries outside the union behave strategically one union member may want to delegate to its partner the ability to set the common external tariff we demonstrate these results in the context of a pure exchange general equilibrium trade model we show that if tariffs are strategic substitutes the union country which is relatively less well endowed in the exported good may be willing to delegate to its partner which behaves more aggressively in setting the union s policy the delegation decision is reversed if tariffs are strategic complements the model extends the standard results on the appropriate level of the union policy by adding another dimension that of the optimal decision making agent

democratic institutions and exchange rate commitments since the collapse of the bretton woods system countries have been able to choose from a variety of exchange rate arrangements we argue that politicians incentives condition the choice of an exchange rate arrangement these incentives reflect the configuration of domestic political institutions particularly electoral and legislative institutions in systems where the cost of electoral defeat is high and electoral timing is exogenous politicians will be less willing to forgo their discretion over monetary policy with a fixed exchange rate in systems where the costs of electoral defeat are low and electoral timing is endogenous politicians are more likely to adopt a fixed exchange rate regime consequently differences in domestic political systems can help account for variations in the choice of exchange rate arrangements we test this argument using constrained multinomial logit and binomial logit on a sample of twenty democracies over the period 1974 95 domestic political institutions have a significant effect on exchange rate regime choice even after controlling for systemic macroeconomic and other political variables

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

credibility and exchange rate management in developing countries abstract the paper discusses the role of credibility factors in the conduct of exchange rate policy in developing countries the analysis is based on a simple framework in which policymakers are concerned about inflation and external competitiveness price setters in the nontradable sector of the economy engage in a strategic game against the authorities the model generates a devaluation bias which undermines the credibility of a fixed exchange rate the role of reputational factors signaling considerations and joining a currency union as possible solutions to this bias is examined

transparency democratic accountability and the economic consequences of monetary institutions debates about the appropriate mix between autonomy and accountability of bureaucrats are relevant to numerous areas of government action i examine whether there is evidence of a tradeoff between transparency democratic accountability and the gains from monetary delegation i begin by presenting a simple theoretical model which suggests that central banks that are transparent in the sense of publishing their macroeconomic forecasts will find it easier to acquire a reputation despite making central banks more subject to outside scrutiny then monetary transparency can lead to improved economic outcomes i also consider arguments about the effect of accountability provisions involving parliamentary oversight and control over central bankers the paper then uses a new data set to examine these issues empirically focusing on a natural experiment involving disinflation costs under different central banking institutions during the 1990s results suggest that countries with more transparent central banks face lower costs of disinflation while accountability provisions have no clear effect on disinflation costs my results also concord with earlier findings that the effect of monetary institutions is conditional on other features of the political environment

seigniorage and the case for national money in countries with high rates of inflation there is typically movement away from the use of the local currency the paper analyzes the costs and benefits of using a local currency with emphasis on the seigniorage foregone by using a foreign money even if it should be desirable for a country to fix its exchange rate it still loses seigniorage if it does not use its own money the case for using a foreign money then turns largely on the superior discipline imposed on domestic policymakers by removing their control over the money supply alternative methods of imposing discipline are discussed estimates of the amount of seigniorage raised by different governments are presented seigniorage amounts in some cases to about 10 percent of government revenue estimates are also presented of both the annual flow and one time stock costs of giving up use of domestic currencies and instead using the dollar the flow cost is typically about 1 percent of gnp and the stock cost is around 10 percent of gnp

optimal soil conservation and the reform of agricultural pricing policies abstract soil degradation is often blamed for the poor performance of agriculture in developing economies so too are policies which keep the prices of both outputs and inputs artificially low some economists have argued that pricing reforms will encourage soil depletion others say that such reforms will encourage soil conservation to evaluate these claims this paper develops models of the optimal control of soil erosion and soil fertility it is shown that the effect could go either way but that there are strong reasons for suspecting that pricing reforms will not affect soil conservation dramatically

loss of monetary discretion in a simple dynamic policy game abstract we analyze a simple policy game featuring monetary credibility problems and argue that loss of monetary discretion is not advantageous two elements form the basis of our analysis firstly we endogenize the source of credibility problems and secondly we consider a dynamic framework where credibility problems are not time invariant by doing this we are able to demonstrate that credibility problems are temporary and in steady state the government has removed these through sound policies a binding policy rule will only serve as an obstacle towards this steady state

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

the political economy of monetary institutions in recent decades countries have experimented with a variety of monetary institutions including alternative exchange rate arrangements and different levels of central bank independence political economists have analyzed the choice of these institutions emphasizing their role in resolving both the time inconsistency problem and dilemmas created by an open economy this first generation work however suffers from a central limitation it studies exchange rate regimes and central bank institutions in isolation from one another without investigating how one monetary institution affects the costs and benefits of the other by contrast the contributors to this volume analyze the choice of exchange rate regime and central bank independence together and in so doing present a second generation of research on the determinants of monetary institutions the articles incorporate both economic and political factors in explaining the choice of monetary institutions investigating how political institutions democratic processes political party competition and interest group pressures affect the balance between economic and distributional policy objectives

central bank reform liberalization and inflation in transition economies an international perspective this paper develops extensive new data on the legal independence of new central banks in 26 former socialist economies fse this data is constructed using the codification system for measuring legal independence developed in cukierman webb and neyapti 1992 and in chapter 19 of cukierman 1992 this makes it comparable with earlier data on central bank independence cbi in the industrial democracies and in non fse developing countries and permits experimentation with alternative indices of cbi like those reviewed in eijffinger and van keulen 1995 the new indices of independence indicate that central bank cb reform in the fse during the nineties has been quite ambitious in spite of the large price shocks induced by the transformation from plan to market reformers in those countries chose to create central banks with levels of legal independence that are substantially higher on average than those of developed economies during the eighties based on data from 1989 through 1998 the evidence in the paper suggests that cbi is unrelated to inflation during the early stages of liberalization but for sufficiently high and sustained levels of liberalization and controlling for variables like price decontrols and wars legal cbi and inflation are significantly and negatively related these findings are consistent with the view that legal cbi no matter how high cannot contain the powerful inflationary impact of wide scale liberalization of formerly controlled prices but once the process of liberalization has gathered sufficient momentum legal independence becomes effective in slowing inflation down and the cumulative liberalization index developed by de melo et al 1996 becomes relatively less important the paper also presents evidence on factors that affect the level of cbi and examines the relation between inflation and cbi within a broader sample composed of the transition and of the developed economies

inflationary finance under discrepion and rules inflationary finance involves first the tax on cash balances from expected inflation and second a capital levy from unexpected inflation from the standpoint of minimizing distortions these capital levies are attractive ex post to the policymaker in a full equilibrium two conditions hold 1 the monetary authority optimizes subject to people s expectations mechanisms and 2 people form expectations rationally given their knowledge of the policymaker s objectives the outcomes under discretionary policy are contrasted with those generated under rules in a purely discretionary regime the monetary authority can make no meaningful commitments about the future behavior of money and prices under an enforced rule it becomes possible to make some guarantees hence the links between monetary actions and inflationary expectations can be internalized there is a distinction between fully contingent rules and rules of simple form a simple rule allows the internalization of some connections between policy act ion and inflationary expectations but discretion permits some desirable flexibility of monetary growth this abstract was borrowed from another version of this item

heterogeneous firms a consumer s report the august title the theory of the firm is well known to every student of economics less well known is what a firm is exactly what it may do or of what use this theory may be in understanding the world w y oi adds substance to our vague outline of a theory in his analysis of heterogeneous firms while posing a definite challenge of explanation for it if the result falls short of the mark it is an interesting attempt nevertheless

the role of policymakers reputation in the ems disinflations abstract it is frequently argued that the ems itself in connection with the high anti inflation reputation of the german bundesbank is responsible for the inflation reduction and convergence which member countries have experienced based on the game theoretical model of backus and driffill 1985 american economic review 75 530 538 an empirical measure of the government s reputation for fighting inflation is derived by using a bayesian learning approach time varying estimates of these counterinflation reputation measures are computed for the original ems member countries and for a control group of major non ems countries the paper finds that only the smaller ems participants have gained anti inflation reputation during the ems period

central bank independence an update of theory and evidence this paper reviews recent research on central bank independence cbi after we have distinguished between independence and conservativeness research in which the inflationary bias is endogenised is reviewed finally the various challenges that have been raised against previous empirical findings on cbi are discussed we conclude that the negative relationship between cbi and inflation is quite robust

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

exchange rate regimes and inflation only hard pegs make a difference abstract using data from a large sample of developing countries from 1985 to 2001 we confirm that hard pegs currency boards or a shared currency reduce inflation and money growth there is no evidence that soft pegs confer any monetary discipline after other factors are controlled for inflation triggers regime switches under hard pegs monetary growth is unaffected by fiscal deficits or by inflation shocks under soft pegs as under floats increased fiscal deficits and positive inflation shocks are associated with higher monetary growth the apparently slower per capita output growth under hard pegs is explained by their geographical distribution jel classification f41

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

invested interests the politics of national economic policies in a world of global finance capital moves more rapidly across national borders now than it has in at least fifty years and perhaps in history this article examines the effects of capital mobility on different groups in national societies and on the politics of economic policymaking it begins by emphasizing that while financial markets are highly integrated within the developed world many investments are still quite specific with respect to firm sector or location it then argues that contemporary levels of international capital mobility have a differential impact on socioeconomic groups over the long run increased capital mobility tends to favor owners of capital over other groups in the shorter run owners and workers in specific sectors in capital exporting countries bear much of the burden of adjusting to increased capital mobility these patterns can be expected to lead to political divisions about whether or not to encourage or increase international capital market integration the article then demonstrates that capital mobility also affects the politics of other economic policies most centrally it shifts debate toward the exchange rate as an intermediate or ultimate policy instrument in this context it tends to pit groups that favor exchange rate stability against groups that are more concerned about national monetary policy autonomy and therefore less concerned about exchange rate stability similarly it tends to drive a wedge between groups that favor an appreciated exchange rate and groups that favor a depreciated one these divisions have important implications for such economic policies as european monetary and currency union the dollar yen exchange rate and international macroeconomic policy coordination

checks and balances private information and the credibility of monetary commitments the authors develop and test several new hypotheses about the anti inflationary effect of central bank independence and exchange rate pegs in the context of different institutions and different degrees of citizen information about government policies theory provides strong reason to believe that while central bank independence will prove more effective as a commitment mechanism in countries where multiple players in government have veto power checks and balances the number of veto players will have no effect on the credibility of exchange rate pegs conversely the authors argue that central bank independence does not solve the problems of commitment that arise when citizens are imperfectly informed about the contribution of government policy to inflation exchange rate pegs however mitigate these problems the authors present extensive evidence from cross country tests using newly developed data that provide strong support for their propositions

transparency reputation and credibility under floating and pegged exchange rates this paper shows that if the cost of importing foreign inflation and real exchange rate shocks are not too high then the equilibrium nominal exchange rate regime for a country with a credibility problem is a peg under which credibility is higher and inflation is lower than under a float this holds true although devaluations of the pegged rate are assumed to be costless the reason is that as realized inflation is not perfectly controllable planned inflation under a float is private information in contrast since the exchange rate can be perfectly controlled pegging resolves the private information problem is more transparent and makes reputation more effective

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

to be or not to be in monetary union a synthesis article i nfo monetary union can benefit countries suffering from policy credibility problems if it eliminates the inflation bias and also allows for more efficient management of certain shocks but it also carries costs as some stabilization may be feasible even in the absence of credibility and this may be more than what an individual country can hope for in a monetary union in this paper we combine the stabilization and credibility branches of the currency union literature and construct a simple welfare criterion that can be used to evaluate alternative monetary arrangements we produce examples where monetary union may be welfare improving even for low modest levels of inflation bias 2 3 as long as business cycles are not too a synchronized across countries

on the credibility of alternative exchange rate regimes abstract most anti inflation plans have used a nominal exchange rate anchor even though many other variables can serve this role the conventional wisdom is that an exchange rate anchor imposes more macroeconomic discipline than other anchors though theory does not yet provide any clear reason why this is so we explain the link between an exchange rate anchor and discipline with a model that assumes that the public can monitor the nominal exchange rate more easily that it can the other variables in our model a barro gordon game of incomplete information with imperfect monitoring we show that serious stabilizers prefer more visible anchors such as the nominal exchange rate we also show that in some circumstances serious stabilizers will choose to fix the exchange rate even when fixed exchange rates have some costs such as diminished capabilities to respond to external shocks

debt poverty and resource management in a rural smallholder economy this paper develops a model to capture the key features of poverty credit constraints and resource management faced by poor rural households we assume that due to the existence of asymmetric information and moral hazard the household faces an increasing cost of credit as its debt equity ratio rises a household exploiting a natural resource may fall into a poverty trap but only if it is unable to afford the increasing borrowing costs implied by increasing debt to allow it to avoid such a trap or if it discounts future utility so much that a balanced growth path cannot be financed at any level of long run borrowing in contrast along an optimal balanced growth path the household s asset wealth purchased inputs resource stock and consumption increase at the same constant rate however over the long run there may be carrying capacity limits that prevent the resource from improving further the household may then direct its savings to accumulating financial assets and eventually under certain conditions may become a net creditor with resource exploitation becoming a less and less important source of its income

the dynamics of exchange rate regimes fixes floats and flips the impermanence of fixed exchange rates has become a stylized fact in international finance the combination of the mirage view that pegs do not really peg with the fear of floating view that floats do not really float generates the conclusion that exchange rate regimes are in practice unimportant for the behavior of the exchange rate this is consistent with evidence on the irrelevance of exchange rate regimes for general macroeconomic performance recent studies however show that the exchange rate regime matters this can be understood by considering the dynamics of exchange rate regimes we demonstrate that the mirage view is somewhat misleading and incomplete pegs frequently break but many do last also there is a high degree of flipping that is the re formation of pegs that have broken thus a fixed exchange rate today is a good predictor that one will exist in the future we also investigate the quantitative effect of fixed exchange rates while the fear of floating view suggests little actual difference in fixed and floating rates with respect to exchange rate volatility we show that fixed exchange rates exhibit considerably greater bilateral exchange rate stability than flexible rates both today and in the future 2007 elsevier b v all rights reserved

exchange rate proclamations and inflation fighting credibility if governments choose economic policies that often run counter to their public commitments are those commitments meaningless we argue that govern ment proclamations can be critical in signaling economic policy intentions we focus on the realm of exchange rate policy in which countries frequently implement an exchange rate regime that differs from the officially declared regime we argue that the official exchange rate regime is one of the most important signals of a government s economic policy preferences when a government makes a de jure public commit ment to a fixed exchange rate it sends a signal to domestic and international markets of its strict monetary policy priorities in contrast a government that proclaims a floating exchange rate signals a desire to retain discretion over monetary policy even if it has implemented a de facto fixed rate we use data on 110 developed and devel oping countries from 1974 to 2004 to test two hypotheses first that governments that adopt de facto fixed exchange rates will experience less inflation when they back up their actions with official declarations and second that governments that abide by their commitments as demonstrated by a history of following through on their public declarations of a fixed exchange rate regime will establish greater inflation fighting credibility within developing countries democratic institutions enhance this credibility results from fixed effects econometric models provide strong support for our hypotheses

deprived land use intensification in shifting cultivation the population pressure hypothesis revisited this article provides a theoretical framework based on optimal control theory to analyze farm households land use intensification decisions in forest based shifting cultivation slash and burn agroecosystems the main results from the analysis generally coincide with the population pressure hypothesis pph as an important driver of soil degradation due to the so called fallow crisis or deprived land use intensification in shifting cultivation however the model also shows from a supply perspective that such a vicious circle of lower yields and greater forest land clearing may be avoided when the production elasticity of on farm labor outweighs the elasticity of substitution between farm labor and soil fertility furthermore using data from shifting cultivating households from yucatan mexico we calibrate the effect of changes in population density the numerical analysis suggests that by contrast to better off households when population density increases poorer shifting cultivating households optimal labor allocation strategy is to further extensify land use by clearing more forest in the village common property land or ejido land

on the imperfect substitutability of policy regimes exchange rate targetting vs policy coordination abstract exchange rate targetting is always an imperfect substitute for explicit policy coordination but succeeds when economies are either structurally dissimilar with symmetric shocks or structurally symmetric with dissimilar shocks a joint commitment then generates economies of scale in interventions

production and investment in natural resource industries there has been a recent tendency for economists to view natural resource scarcity as a diminishing threat to man s existence and his ability to produce an abundant supply of worldly goods see john v krutilla this change in view has emanated from the world s experience of the last few decades with technological development and the absence of any evidence that this rapid accumulation of technical knowledge will cease in some respects one might think that modern technology has removed the need for an economic theory of conservation temporal allocation of natural resources on the other hand conservation of natural resources can now be looked upon with less emotion since the dire consequences of too rapid exploitation are no longer a threat the question of conservation is thus a cold economic problem removed from many of its older value connotations there is indeed considerable effort taking place in the economics profession to fill this need for a quantitative economic theory of conservation however with one exception vernon smith focus has been limited to specific resources earlier works by lewis c gray and harold hotelling concerning the theory of the mine have recently been extended in numerous papers see r cummings and 0 burt richard l gordon anthony scott 1967 problems associated with petroleum production are considered in paul davidson and the fishery is considered in j a crutchfield and arnold zellner h scott gordon james quirk and vernon smith anthony scott 1955 and ralph turvey an extensive literature exists on the temporal allocation of groundwater two recent contributions are gardner brown and charles b mcguire and burt a logical problem has been encountered however in efforts to examine the optimum allocation of a natural resource over time without explicitly considering the rate of investment associated with resource use this difficulty stems from the long life of many capital items used in the process of exploiting the natural resource earlier studies have either tacitly or explicitly amortized costs of investment associated with resource use and proceeded as though all costs of production were essentially variable smith was the first to explicitly bring capital investment into a production model for natural resources and his work was followed by the authors where only exhaustible resources were considered more recently quirk and smith have introduced a dynamic model of the fishery in which capital investment is treated explicitly it seems then that there is a need for a comprehensive model for simultaneously optimizing the rate of resource use and investment in natural resource industries

evolutionary processes in soil conservation policy this paper summarizes and interprets part of the history and some of the apparent evolutionary processes of past soil conservation policy and identifies the underlying social objectives of these policies the findings are compared to those social objectives that economics identifies as the legitimate pursuits of government it concludes that soil conservation will continue to be an important policy concern as institutions mature and nonpoint pollution policy becomes better developed because of its persisting relevance to both water quality and the future vitality of agriculture 23 references

can equilibrium models explain nominal exchange regime non neutrality evidence from the european monetary system abstract in a recent paper alan stockman argues that the finding that real exchange rate variability id higher under flexible nominal exchange rate systems than under fixed nominal exchange rate systems typically interpreted as evidencee of price stickiness is consistent with equilibriu models stockman s theory we argue predicts that the formation of the european monetary system should have had no effect on the real exchange rate variability of its members we test this prediction and interpret our findings as evidence in support of stockman s theory although not as evidence that equilibrium models can account for nominal exchange regime non neutrality jel f31

the international monetary system in the last and next 20 years the last two decades have seen far reaching changes in the structure of the international monetary system europe moved from the european monetary system to the euro china adopted a dollar peg and then moved to a basket band and crawl in 2005 emerging markets passed through a series of crises leading some to adopt regimes of greater exchange rate flexibility and others to rethink the pace of capital account liberalization interpreting these developments is no easy task some observers conclude that recent trends are confirmation of the bipolar view that intermediate exchange rate arrangements are disappearing while members of the fear of floating school conclude precisely the opposite we show that the two views can be reconciled if one distinguishes countries by their stage of economic and financial development among the advanced countries intermediate regimes have essentially disappeared this supports the bipolar view for the group of countries for which it was first developed within this subgroup the dominant movement has been toward hard pegs reflecting monetary unification in europe while emerging markets have also seen a decline in the prevalence of intermediate arrangements these regimes still account for more than a third of the relevant subsample here the majority of the evacuees have moved to floats rather than fixes reflecting the absence of emu like arrangements in other parts of the world among developing countries the prevalence of intermediate regimes has again declined but less dramatically where these regimes accounted for two thirds of the developing country subsample in 1990 they account for a bit more than half of that subsample today as with emerging markets the majority of those abandoning the middle have moved to floats rather than hard pegs the gradual nature of these trends does not suggest that intermediate regimes will disappear outside the advanced countries anytime soon barry eichengreen and raul razo garcia

mobile capital domestic institutions and electorally induced monetary and fiscal policy the literature on global integration and national policy autonomy often ignores a central result from open economy macroeconomics capital mobility constrains monetary policy when the exchange rate is fixed and fiscal policy when the exchange rate is flexible similarly examinations of the electoral determinants of monetary and fiscal policy typically ignore international pressures altogether we develop a formal model to analyze the interaction between fiscal and monetary policymakers under various exchange rate regimes and the degrees of central bank independence we test the model using data from oecd countries we find evidence that preelectoral monetary expansions occur only when the exchange rate is flexible and central bank independence is low preelectoral fiscal expansions occur when the exchange rate is fixed we then explore the implications of our model for arguments that emphasize the partisan sources of macroeconomic policy and for the conduct of fiscal policy after economic and monetary union in europe

heterogeneous firms and the organization of production firms in the same industry exhibit systematic differences in the organization of production and the structure of employment entrepreneurial ability is the specific scarce input that limits the size of a firm this input must be allocated to two activities coordinating production and monitoring workers able entrepreneurs can convert calendar time into larger supplies of coordinating effort that enable them to assemble large firms greater ability implies a higher shadow price of time which increases the implicit costs of monitoring a dispersion of entrepreneurial abilities generates an equilibrium size distribution of firms differences in monitoring costs affect the choice of worker productivities the design of products and the organization of production the monitoring cost hypothesis advanced in this paper goes a long way in explaining the equilibrium of an industry containing heterogeneous firms that differ in size and behavior

fiscal rules and government borrowing costs international evidence we find that the adoption of numerical fiscal rules reduces government borrowing costs in a sample of 101 advanced and developing countries for 1985 2010 we apply a variety of propensity score matching methods to address the self selection problem of policy adoption and find strong evidence that fiscal rules have large and significant treatment effects on lowering government borrowing costs in both international and domestic financial markets the results are robust to changes in country sample and alternative estimation methodology and are consistent with fiscal rules helping to build policy credibility by reducing the probability of default and the risk premium on government debt that compensates lenders for this possibility jel e43 g12 h60

the phillips curve the persistence of inflation and the lucas critique evidence from exchange rate regimes comment we present evidence from the united states and the united kingdom that the persistence of price inflation is significantly higher under managed exchange rate regimes than under gold based fixed exchange rate regimes these differences are also reflected in expectations augmented phillips curves we use a two country macro model with forward looking price setters to demonstrate that higher monetary accommodation of inflation and exchange rate accommodation of inflation differentials increase inflation persistence the evidence does not contradict this hypothesis it supports the hypothesis of forward looking price setters and highlights the empirical significance of the lucas critique jel e31 e42 f33

from participation to adoption comparing the effectiveness of soil conservation programs in the peruvian andes many efforts are made to promote soil conservation in developing countries this paper compares the effect of two programs promoting soil conservation in peru on the adoption decision of households one program applies a top down approach with soil conservation as its core activity the other program applies a participatory approach offering a portfolio of activities in order to improve rural livelihoods the decisions on participation and adoption are estimated with a trivariate probit model the results show that each program attracts different types of households and achieves different outcomes in terms of soil conservation

fewer monies better monies in the aftermath of emerging market crises from russia to asia and latin america there is a quest for better monetary arrangements that are more crisis proof fixed rates are out flexible rates are in with a policy focus on inflation targeting but there is of course the alternative of abolishing exchange rates all together this paper revisits the issue of dollarization or currency boards to review what arguments in the debate stand up the case for flexible exchange rates emphasizes the need for a tool to accomplish relative price adjustment this paper argues that in an intertemporal perspective most shocks require financing in the capital market rather than adjustment moreover countries frequently do not use their flexible rate to play a cyclical role and as a result only a pay a premium for the option to depreciate but do not take advantage of the flexibility on the contrary they engineer systematic overvaluation in the context of inflation targeting

central bank independence centralization of wage bargaining inflation and unemployment theory and some evidence abstract this paper proposes a conceptual framework to investigate the effects of central bank independence of the degree of centralization of wage bargaining and of the interaction between those institutional variables on real wages unemployment and inflation in a framework in which unions are averse to inflation this aversion moderates union s wage demands as they attempt to induce the central bank to inflate at a lower rate an increase in the degree of centralization of wage bargaining a decrease in the number of unions triggers two opposite effects on real wages unemployment and inflation it reduces the substitutability between the labor of different unions and therefore the degree of effective competition between them this reduced competition effect raises real wages unemployment and inflation but the decrease in the number of unions also strengthens the moderating effect of inflationary fears on the real wage demands of each union this strategic effect lowers real wages unemployment and inflation for sufficiently inflation averse unions the interaction between those two effects produces a calmfors driffill type relation between real wages and centralization the paper analyzes the effects of central bank independence on the position and the shape of this relation as well as on inflation and unemployment the paper features two mechanisms one of which is novel through which monetary institutions have real effects the model implies that if there is a single union social welfare is maximized when the central bank attaches a zero weight to inflation but when the number of unions is larger than one this result is no longer true in general empirical evaluation of some of the theoretical implications using data from 19 developed economies is for the most part supportive of those implications
