the classification and performance of alternative exchange rate systems abstract owing to dissatisfaction with the imf s de jure classification of exchange rate regimes a substantial literature has emerged presenting de facto classifications of exchange rate systems and using the latter classifications to compare performances of alternative regimes in terms of key macroeconomic variables this paper critically reviews the literature on de facto regimes in particular the paper 1 describes the main methodologies that have been used to construct de facto codings 2 surveys the empirical literature generated by de facto regime codings and 3 lays out the problems inherent in constructing de facto classifications the empirical literature is found to yield few robust findings we argue that the as yet unfulfilled objective of this literature and the major research agenda for the future in this area lies in the need of a more thorough investigation of the degree of monetary policy independence without relying exclusively on movements in exchange rates an agenda the attainment of which is made especially challenging because of the lack of comprehensive and reliable data on reserves and interest rates

an empirical analysis of wage dispersion and efficiency wages the main purpose of this study is to examine inter industry wage differentials in sweden after controlling for individual and job characteristics the results indicate that these differentials are substantial the ranking of the differentials was stable over time while the dispersion of wage premiums fell by 50 per cent during the period 1968 81 a period of strong efforts to reduce wage dispersion in sweden the relation between industry wage premiums and a number of industry characteristics is also examined along with new evidence which is in line with the shirking model hypothesis on the relation between wages and worker control

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

confronting the environmental kuznets curve t he environmental kuznets curve posits an inverted u relationship between pollution and economic development kuznets s name was apparently attached to the curve by grossman and krueger 1993 who noted its resemblance to kuznets s inverted u relationship between income inequality and development in the first stage of industrialization pollution in the environmental kuznets curve world grows rapidly because people are more interested in jobs and income than clean air and water communities are too poor to pay for abatement and environmental regulation is correspondingly weak the balance shifts as income rises leading industrial sectors become cleaner people value the environment more highly and regulatory institutions become more effective along the curve pollution levels off in the middle income range and then falls toward pre industrial levels in wealthy societies the environmental kuznets curve model has elicited conflicting reactions from researchers and policymakers applied econometricians have generally accepted the basic tenets of the model and focused on measuring its parameters their regressions typically fitted to cross sectional observations across countries or regions suggest that air and water pollution increase with development until per capita income reaches a range of 5000 to 8000 when income rises beyond that level pollution starts to decline as shown in the conventional ekc line in figure 1 in developing countries some policymakers have interpreted such results as conveying a message about priorities grow first then clean up numerous critics have challenged the conventional environmental kuznets curve both as a representation of what actually happens in the development process and as a policy prescription some pessimistic critics argue that crosssectional evidence for the environmental kuznets curve is nothing more than a

survey measures of expected u s inflation of real interest rates and cash flows for decisions concerning investment expenditures international capital flows and exchange rate movements hinge in large part on expected real yield differentials across countries the federal reserve needs reliable measures of expected inflation to formulate and gauge the thrust of monetary policy in fact inflation expectations have become more important to the fed given the diminished stability of the link between the monetary aggregates and gdp expenditures since the early 1980s and the greater role which has been thrust upon expected real short term interest rates in the implementation of federal reserve policy the issue of rationality of inflation expectations that is the extent to which agents form expectations without making systematic mistakes in their beliefs about what inflation will be is important if inflation expectations are formed rationally labor and financial markets will strongly tend to neutralize the potential redistributive effects of inflation over time financial capital will flow efficiently within and across national borders moreover some of the stronger claims of new classical macroeconomics like the claim that only unexpected monetary policy actions will

an alternative analysis of apparent ekc type transitions abstract the hypothesis of the environmental kuznets curve ekc depends upon the assumption that countries pass through a similar environmental impact trajectory as they experience income growth implying that income levels determine pollution levels the authors present evidence that this is not representative of the way many individual country s pollution emission trajectories evolve and question the emphasis on income determinism by the ekc the study proposes that nonlinear dynamic systems analysis provides a more complete description of individual country pollution trajectories in the case of co 2 emissions the nonlinear time trajectories show abrupt transitions that occur contemporaneously with historical events and over a broad range of incomes

political influence on the central bank international evidence political influence on the central bank is measured bere by looking at the probability that a central bank governor will be replaced shortly after a political change of government the governor changes about half the time witbin six months of a nonconstitutional or other radical change of government a military coup or a restoration of democracy the governor is much less likely to change within six months following a routine change in the head of government about one fourth of the time in developing countries and one tenth in industrial countries these indicators vary across countries and correlate statistically with inflation and its variability and with real growth and real interest rates differences in the vulnerability of the central bank to political instability in political instability itself and in central bank turnover in nonpolitical periods seem to be a major part of the explanation for why developing countries have on average higher and more variable inflation than industrial countries do

classifying exchange rate regimes deeds vs words abstract most of the empirical literature on exchange rate regimes uses the imf de jure classification based on the regime announced by the governments despite the recognized inconsistencies between reported and actual policies in many cases to address this problem we construct a de facto classification based on data on exchange rates and international reserves from all imf reporting countries over the period 1974 2000 which we believe provides a meaningful alternative for future empirical work on the topic the classification sheds new light on several stylized facts previously reported in the literature in particular we find that the de facto pegs have remained stable throughout the last decade although an increasing number of them shy away from an explicit commitment to a fixed regime hidden pegs we confirm the hollowing out hypothesis but show that it does not apply to countries with limited access to capital markets we also find that pure floats are associated with only relatively minor nominal exchange rate volatility and that the recent increase in the number of de jure floats goes hand in hand with an increase in the number of de facto dirty floats fear of floating

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

central bank independence and output variability abstract the benefit of greater central bank independence is the reduction in inflation that should result from the mitigation of a country s time consistency problem the cost of greater independence is the loss of discretionary monetary policymaking and consequent increase in output variability empirically however there is no correlation between output variability and central bank independence a possible explanation for this lack of correlation is that countries which are more likely to have lower output variability are also more likely to choose to have an independent central bank this hypothesis is tested using data for 44 countries while the evidence is weakly consistent with this hypothesis this does not seem sufficient to explain the zero correlation between output variability and central bank independence

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

why sweden s welfare state needed reform according to professor walter korpi the swedish economy would be in better shape if leading politicians had paid less attention to the advice from an influential group of swedish academic economists allegedly hostile to the welfare state their claim that high taxes and extensive social security programmes have strong adverse effects on aggregate economic performance rested on a politically biased reading of comparative international data in purporting to show that sweden had fallen behind other comparable countries the sclerosis diagnosis they set the stage for cutbacks in the welfare state and a major tax reform involving substantially lower marginal tax rates apart from creating inequality at a negligible gain in efficiency the very same reforms may also explain why sweden ran into a macroeconomic tailspin in the early i 990s rather than an instructive case study of the ultimate consequences of a long term obsession with income equality and social protection the exceptional economic crisis can be traced to severe macroeconomic policy blunders the views of professor korpi are quite familiar for anyone that has followed the swedish debate over the last decade supporters of the welfare state applaud professor korpi for revealing the ideological bias underlying the evidence presented in support of the sclerosis diagnosis some swedish economists rather thank of him as a modern day don quixote eager to pick a fight with imaginary villains being a swede and a professor of economics i can hardly claim the status of an impartial observer i certainly believe that harberger triangles convey information and i am convinced that most of the recently implemented reforms make sense nevertheless i believe that professor korpi raises important issues many of the accusations made against the welfare state in sweden and elsewhere rest on evidence which does not survive normal academic scrutiny in their capacity as policy advisors academic economists far from always live up to the standards of the seminar room speculation and sweeping generalisations are poor substitutes for facts and empirical investigations like professor korpi i doubt that very important insights on the harmfulness of the welfare state can be gained from comparative aggregate data over the period i970 90 swedish economic growth was below the oecd average at the same time the public sector was very large however

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

economic prescriptions for environmental problems how the patient followed the doctor s orders o ne of the dangers with ivory tower theorizing is that it is easy to lose sight of the actual set of problems which need to be solved and the range of potential solutions as one who frequently engages in this exercise i can attest to this fact in my view this loss of sight has become increasingly evident in the theoretical structure underlying environmental economics which often emphasizes elegance at the expense of realism in this paper i will argue that both normative and positive theorizing could greatly benefit from a careful examination of the results of recent innovative approaches to environmental management the particular set of policies examined here involves two tools which have received widespread support from the economics community marketable permits and emission charges pigou 1932 dales 1968 kneese and schultze 1975 both tools represent ways to induce businesses to search for lower cost methods of achieving environmental standards they stand in stark contrast to the predominant command and control approach in which a regulator specifies the technology a firm must use to comply with regulations under highly restrictive conditions it can be shown that both of the economic approaches share the desirable feature that any gains in environmental quality will be obtained at the lowest possible cost baumol and oates 1975 until the 1960s these tools only existed on blackboards and in academic journals as products of the fertile imaginations of academics however some countries have recently begun to explore using these tools as part of a broader strategy for managing environmental problems

central bank independence and macroeconomic performance some comparative evidence this note uses information on a sample of sixteen oecd countries to assess the relationship between central bank independence and macroeconomic performance as previous work suggests politically controlled central banks are more likely to pursue policies that lead to high and variable inflation however the authors find little evidence that political control of central bank policy has any impact on measures of the level or variability of growth unemployment or the ex ante real interest rate copyright 1993 by ohio state university press

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

positive externalities of domestic biogas initiatives implications for financing domestic biogas programs are often justified on the basis of the private benefits and costs accruing to the individual households in terms of providing a superior cooking fuel improved indoor air quality and saving of time spent on collecting firewood this paper contends however that the economic surpluses from domestic biogas programs are realized beyond such narrowly defined project boundaries the paper maintains that economic value addition from the consumptive use of the biogas for cooking and the non consumptive and indirect value derived from the biogas plant providing feedstock for other processes and other such benefits as greenhouse gas mitigation positive externalities need to be accounted for the process approach adopted by this paper would enable an integrated view of the value chain and consequently a mechanism to reallocate costs and to distribute such surpluses

two fallacies concerning central bank independence this paper takes issue with two basic conclusions prevalent in the literature on central bank behavior first the paper argues that it is inappropriate to presume that central banks will in the absence of any precommitment technology necessarily behave in a discretionary fashion that implies an inflationary bias since there is no functional connection between average rates of money creation or inflation and policy responsiveness to cyclical disturbances it is entirely feasible for the bias to be avoided in other words there is no necessary tradeoff between flexibility and commitment second to the extent that the absence of any absolute precommitment technology is nevertheless a problem it will apply to a consolidated central bank plus government entity as well as to the central bank alone thus contracts between governments and central banks do not overcome the motivation for dynamic inconsistency they merely relocate it this abstract was borrowed from another version of this item

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

international experiences with different monetary policy regimes any views expressed in this paper are those of the author only and not those of columbia university or the national bureau of economic research abstract this paper examines the international experiences with four basic types of monetary policy regimes 1 exchange rate targeting 2 monetary targeting 3 inflation targeting and 4 monetary policy with an implicit but not an explicit nominal anchor the basic theme that emerges from this analysis is that transparency and accountability are crucial to constraining discretionary monetary policy so that it produces desirable long run outcomes because the devil is in the details in achieving transparency and accountability what strategy will work best in a country depends on its political cultural and economic institutions as well as on its past history

labour market policies and unemployment in the oecd unemployment policies richard jackman christopher pissarides and sawas savouri the massive increase in unemployment throughout the oecd since the early 1970s has led governments in many countries to introduce or to expand labour market policies such as training schemes employment subsidies public works or schemes of counselling or assistance in job search such programmes have the objective of reducing unemployment by improving the workings of the labour market after a description of these programmes this article proposes a framework based on the relationship between unemployment and vacancies or beveridge curve within which the rise in unemployment can be analysed and the effects of policies and of institutions examined this framework helps to identify the main factors which have affected the unemployment and vacancy rates in 14 of the main oecd countries over the period 1970 88 the main results are that while corporatism remains the institutional feature with the biggest single impact in sustaining low unemployment rates labour market policies also have had a significant and well defined effect on unemployment which appears large relative to the budgetary costs of the programmes

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

what causes the failure of inflation stabilization plans abstract the paper discusses the causes of failure of inflation stabilization plans following a description of stylized facts of inflation stabilization a model of balance of payments crises is presented highlighting some of the main factors leading to the collapse of stabilizations empirical results obtained when estimating a binary probit model over a panel of 34 stabilizations identify real exchange rate appreciation lack of foreign reserves and government budget deficits as the main causes of failure of inflation stabilization plans this is consistent with the model presented in this paper with the stylized facts of stabilizations and with some of the models found in the literature

labour market policy and unemployment the paper discusses three aspects of the system for unemployment support first active labour market programmes as a means of re allocating labour from high unemployment to low unemployment sectors are analysed and it is concluded that wage raising accommodation effects may be a serious problem second the possibility of strengthening incentives for wage moderation by differentiating employee and or employer contributions to unemployment insurance are discussed third the question is raised whether there may exist other institutional set ups for providing unemployment support that are more efficient in terms of returning the unemployed to work than government run systems

the pollution terms of trade and its five components abstract based on two extensions this paper proposes a re appraisal of the concept of the pollution terms of trade ptt introduced by antweiler 1996 first detailed data allows capturing the effect of differences in emission intensities across countries and over time second relying on johnson and noguera 2012 the revised ptt index controls for trade in intermediate goods and is based on value added rather than gross output figures applied to a database for so 2 emission intensities for 62 developed and developing countries over the 1990 2000 period it turns out that the first extension has a larger empirical importance than the second one the global pattern is one in which the major rich economies exhibit a ptt index below one higher pollution intensity in imports than in exports trade imbalances tend to exacerbate this asymmetry allowing rich economies to further offshore their pollution through trade

the swedish experiment the deterioration of the economic performance in sweden from about 1970 was to some extent the result of a number of exogenous shocks and unnecessary policy mistakes it was however also related to basic changes in the economic and social system in sweden in the late 1960s and early 1970 when government spending taxes and regulations started to expand dramatically it is also argued in the paper that problematic political economic and social mechanisms had become embedded in the long term dynamics of the system itself these various experiences are the background for recent reforms and retreats of the swedish experiment

poverty and pollution abatement evidence from lead phase out abstract an extensive literature suggests that poverty prevents nations from abating many forms of pollution considerable research also proposes a competing claim that poverty delays but does not prevent pollution abatement neither position enjoys persuasive empirical support data describing the phase out of leaded gasoline allow for empirical investigation and they support the latter claim that poverty delays but does not prevent pollution abatement many poor nations have solved the problem of vehicular lead pollution and they have tended to follow rich nations in doing so the phase out achievements of richer nations have generated much of the ability and will that has enabled poor countries to solve the problem the pattern of abatement sequencing and its root causes present important implications for environmental policy and research

does central bank independence really matter new evidence for developing countries using a new indicator abstract this paper provides a new indicator for central bank independence cbi based on the turnover rate of central bank governors for 82 developing countries over the period 1980 1989 using this new indicator it is concluded that this proxy for cbi is related to inflation only if the high inflation countries are included in the sample the view that both cbi and inflation are caused by effective opposition towards inflation is not supported using both the extreme bound analysis and sala i martin s method we do not find evidence that cbi is robustly related to economic growth

globalization pressures and the state the worldwide spread of central bank independence the authors examine the impact of globalization on state structures in the specific instance of the central bank following the world system world society and neoinstitutional perspectives in sociology they assume that states are in cultural political and economic competition with each other thereby seeking to maintain their position and status frequently by adopting organizational forms or practices that make them isomorphic with their environment the authors predict that countries boost the independence of their central bank from the political power as their exposure to foreign trade investment and multilateral lending increases they also model the cross national dynamic process of diffusion of central bank independence by examining the impact of cohesive and role equivalent trade relationships between countries they find support for their hypotheses with information on 71 countries between 1990 and 2000

kicking the habit moving from pegged rates to greater exchange rate flexibility why do governments find it so difficult to move from pegged exchange rates to greater exchange rate flexibility i first establish that there is a problem to be solved that there are powerful incentives for greater flexibility deriving from changes in the international economic and financial environment but that policymakers find it difficult to engineer a smooth transition i offer practical suggestions and a framework under which the probability of a smooth transition can be maximised drawing examples from recent economic history i then attempt to understand the experience of selected countries which have undertaken this transition

insider effects in wage determination abstract the paper attempts to shed new light on the determinants of industry wages by a cross country comparison of wage setting relationships making use of comprehensive and consistent panel data on industries from the early 1960s to the mid 1980s the empirical analysis involves estimations of identically specified industry wage equations for each of five countries sweden norway finland germany and the united states a key finding is that industry wages in the u s are the most responsive to sectoral price and productivity changes by contrast industry wages in the nordic countries are largely unaffected by sectoral conditions the results cast doubt on the competitive model as an accurate characterization of wage setting under decentralization

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
