currency unions in africa is the trade effect substantial enough to justify their formation using estimates that currency unions double trade we quantify the welfare effects of forming currency unions for the african regional economic communities and for the african union as a whole the potential increase in trade is shown to be small and much less than that resulting from the adoption of the euro allowing for increased african trade does not overturn the negative assessment of african currency unions due to asymmetries in countries terms of trade shocks and their degree of fiscal discipline

measuring the efficiency of china s carbon market a comparison between efficient and fractal market hypotheses abstract in this study variance ratio test and detrended fluctuation analysis are adopted to measure the efficiencies of beijing guangdong hubei shanghai shenzhen tianjin and chongqing seven carbon markets in china the empirical results indicate that on the basis of efficient market hypothesis adopts variance ratio test hubei and guangdong markets are weak efficient beijing shenzhen and shanghai markets are inefficient and the efficiencies of tianjin and chongqing are uncertain under daily returns all seven carbon markets are weak efficient under weekly returns on the basis of fractal market hypothesis hurst exponents are obtained by detrended fluctuation analysis shanghai guangdong and hubei markets are weak efficient the other four markets are inefficient under daily returns beijing and hubei markets are weak efficient and the other five markets are inefficient under weekly returns on the whole the efficiencies of china s carbon markets are generally low combining the empirical results with the reality of china s carbon markets it s proved that the results of fractal market hypothesis are more convincing in comparison to efficient market hypothesis fractal market hypothesis can more effectively measure the efficiency of carbon market

nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

monetary union in west africa and business cycles synchronicity new evidence in the light of the initiative of the west african monetary zone wamz to introduce a common currency by 2020 this paper investigates the intricacies of the business cycles synchronicity among the six countries given i the rising importance of trade and cooperation with china ii the consideration of the euro as a potential anchor currency and a vehicle for trade with the eurozone and iii the importance of nigeria as the largest country of the group and the main supplier of oil we investigate the relative importance of these three major players in having their business cycles linked with the group in addition we investigate the underlying determinants of the business cycles synchronicity among the wamz countries on a pairwise basis results show a clear dominance of china s business cycle synchronicity with the wamz over europe s and nigeria s trade integration emerges as the key underlying factor of the common cycle observed

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

capital controls capital flow contractions and macroeconomic vulnerability abstract in this paper i analyze whether restrictions to capital mobility reduce vulnerability to external shocks more specifically i ask if countries that restrict the free flow of international capital have a lower probability of experiencing a large contraction in net capital flows i use three new indexes on the degree of international financial integration and a large multi country data set for 1970 2004 to estimate a series of random effect probit equations i find that the marginal effect of higher capital mobility on the probability of a capital flow contraction is positive and statistically significant but very small having a flexible exchange rate greatly reduces the probability of experiencing a capital flow contraction the benefits of flexible rates increase as the degree of capital mobility increases a higher current account deficit increases the probability of a capital flow contraction while a higher ratio of fdi to gdp reduces that probability

de facto exchange rate regimes and currency crises are pegged regimes with capital account liberalization really more prone to speculative attacks abstract this paper empirically examines whether de facto exchange rate regimes affect the occurrence of currency crises in 84 countries over the 1980 2001 period by using the probit model we employ the de facto classification of reinhart and rogoff 2004 that allows us to estimate the impact of relatively long lived exchange rate regimes on currency crises with much greater precision we find that pegged regimes significantly decrease the likelihood of currency crises compared with floating regimes by using the combined data of exchange rate regimes and the existence of capital controls we also find interesting evidence that pegged regimes with capital account liberalization significantly lower the likelihood of currency crises compared with other regimes these results are robust to a wide variety of samples and models from the standpoint of the macroeconomic policy trilemma we can conjecture that pegged regimes with capital account liberalization are substantially less prone to speculative attacks because they can enhance greater credibility in their currencies by abandoning monetary policy autonomy

the walking debt crisis abstract this article sheds light on the question whether arising sovereign credit risk in the emu has been triggered by the us subprime crunch by adapting recent econometric methodologies suggested in the related field of speculative bubbles we find clear evidence for fast diverging and even explosive behavior of emu government bond yields of peripheral countries relative to germany during the financial and the european debt crisis this might be caused by flight to quality effects to german government bonds coincident with the collapse of lehman brothers and by a loss of confidence in the fiscal stability of greece ireland italy portugal and spain during the european debt crisis first we find compelling evidence for bubbles in the dow jones equity real estate investment trusts reits index which serves as a weekly measure of economic activity in the north american real estate sector second in our main analysis we test whether the collapsing bubble in the housing market triggered the diverging government bond yields during two crisis regimes our findings indicate that this was the case in the course of the financial crisis but not during the emu sovereign debt crisis these results suggest that the severe fiscal problems in peripheral countries are homemade rather than imported from the us

monetary union in west africa who might gain who might lose and why we develop a model in which governments financing needs exceed the socially optimal level because public resources are diverted to serve the narrow interests of the group in power from a social welfare perspective this results in undue pressure on the central bank to extract seigniorage monetary policy also suffers from an expansive bias owing to the authorities inability to precommit to price stability such a conjecture about the fiscal monetary policy mix appears quite relevant in africa with deep implications for the incentives of fiscally heterogeneous countries to form a currency union we calibrate the model to data for west africa and use it to assess proposed ecowas monetary unions fiscal heterogeneity indeed appears crit ical in shaping regional currency blocs that would be mutually beneficial for all their members in particular nigeria s membership in the configurations currently envisaged would not be in the interests of other ecowas countries unless it were accompanied by effective containment on nigeria s financing needs jel classification e58 e61 e62 f33 union monetaire en afrique de l ouest qui pourrait gagner qui pourrait perdre et pourquoi les auteurs developpent un modele dans lequel les besoins financiers des gouvernements depassent le niveau socialement optimal parce que des ressources pub liques sont detournees de maniere aservir les interets etroits du groupe au pouvoir dans une perspective de bien etre social cela entraine des pressions indues sur la banque centrale pour qu elle extraie du seigneuriage la politique monetaire souffre

the allocation of credit and financial collapse this paper examines the allocation of credit in a market in which borrowers have greater information concerning their own riskiness than do lenders it illustrates that 1 the allocation of credit is inefficient and at times can be improved by government intervention and 2 small changes in the exogenous risk free interest rate can cause large discontinuous changes in the allocation of credit and the efficiency of the market equilibrium these conclusions suggests a role for government as the lender of last resort

estimating systemic risk in the international financial system this paper develops three distinct methods to quantify the risk of a systemic failure in the global banking system we examine a sample of 334 banks representing 80 of global bank equity in 28 countries around five global financial crises our results suggest statistically significant but economically small increases in systemic risk although policy responses are endogenous the low estimated probabilities suggest that the distress of central bankers regulators and politicians about the events we study could be overstated and that current policy responses to financial crises could be adequate to handle major macroeconomic events

a pragmatic approach to capital account liberalization in the mid 1990s mainstream economists of nearly all stripes commonly recommended capital account liberalization that is allowing a free flow of funds in and out of a country s economy as an essential step in the process of economic development but then came the east asian financial crisis of 1997 98 in which even seemingly healthy and well managed economies like those of south korea were engulfed by massive capital outflows and tremendous currency volatility and capital account liberalization became quite controversial in the economics profession a decade later now that time has quelled passions and intervening research can shed more light on the debate it appears that both the costs and benefits of capital account liberalization may have been misunderstood in that earlier debate now it appears that the main benefits of capital account liberalization for emerging markets are indirect more related to their role in building other institutions than to the increased financing provided by capital inflows and these indirect benefits are important enough that countries should look for creative approaches to capital account liberalization that would help attain these benefits while reducing the risks countries don t have much choice but to plan for capital account liberalization because capital accounts are de facto becoming more open over time whatever governments may do to try to control them

integracao financeira e reformas institucionais this article intends to analyze the collateral impacts of financial integration process emphasizing its eects on the incentives to the promotion of countries institutional reforms the study tests the hypothesis that capital account openness can stimulate institutional reforms to increase economic freedom and reduce the political and the economic transaction risks given that it represents a channel for punishment to the adoption of policies considered not appropriate by the market the result of our sample with 39 developing and developed countries are favorable evidences of this hypothesis the study also indicates that the index capturing the institutions quality has significant changes for three periods after the year the country is considered financially integrated

financial globalisation and crisis institutional transformation and equity this paper comprises the long introduction to the symposium of five papers on financial globalisation published in the cambridge journal of economics volume 34 no 2 the paper discusses the impact of financial globalisation in a variety of spheres and shows how the five papers link together to provide a coherent view of the current economic and financial crisis in this paper we also examine the globalisation of finance more broadly both in historical terms as well as in relation to the current widespread failure in the financial markets we take up the policy question of how the interests of the poor in particular and developing countries in general could be safeguarded from the vagaries of financial globalisation questioning how much choice communities and countries have and what can the international community do to extend these choices

are financial development and trade openness complements or substitutes this article studies the long and short run relationships between financial development and trade openness using the pooled mean group estimator of pesaran shin and smith 1999 for unbalanced panel data for 87 countries over the 1960 2005 period our empirical results indicate that long run complementarity between financial development and trade openness coexists with short run substitutionarity between the two policy variables but when splitting the data into oecd and non oecd country groups this finding can be observed only in non oecd countries for oecd countries financial development has negligible effects on trade in addition we find nonlinearity in the relationship in that long run responses of trade decrease with financial development the article further finds coexistence of negative trade effects of financial fragility and positive trade impacts of financial depth

unique equilibrium in a model of self fulfilling currency attacks even though self fulfilling currency attacks lead to multiple equilibria when fundamentals are common knowledge we demonstrate the uniqueness of equilibrium when speculators face a small amount of noise in their signals about the fundamentals this unique equilibrium depends not only on the fundamentals but also on financial variables such as the quantity of hot money in circulation and the costs of speculative trading in contrast to multiple equilibrium models our model allows analysis of policy proposals directed at curtailing currency attacks

international financial crises causes prevention and cures dale jorgenson has bestowed a great honor and no small challenge by inviting me to give this lecture a great honor because of the distinguished list of economists who have preceded me a challenge because of the standard they have set and because there is no greater challenge for any economist than providing a coherent account of significant events to his scientific peers i am sometimes asked by friends about the differences between academic life and life as a public official there are many two stand out first as an academic the gravest sin one can commit is to sign one s name to something one did not write as a public official it is a mark of effectiveness to do so as often as possible second as an academic if a problem is too hard and does not admit of a satisfactory solution there is an obvious response work on a different problem that is not a luxury that one has in government i have been reminded of this often in recent years as we have grappled with financial crises in a number of what had previously been considered emerging markets with unrestrained futures anyone who doubts the social importance of what economists do should consider the debates surrounding these crises hundreds of millions of people who expected rapidly rising standards of living have seen their living standards fall hundreds of thousands if not millions of children have been forced to drop out of school and go to work hundreds of billions of dollars of apparent wealth has been lost the stability of large nations as nations has been called into question and the united states has made its largest nonmilitary foreign policyrelated financial commitments since the marshall plan almost all the issues involved in understanding preventing and mitigating these crises are the stuff of economics courses and research fixed versus flexible exchange rates moral hazard and multiple equilibria speculation and liquidity fiscal and monetary policies regulation and competition what economists think say and do has profound implications for the lives of literally billions of their fellow citizens whether it is discussing the role of derivatives in signaling exchange rate commitments with chinese premier zhu rongji or discussing an nber working paper on inflation targeting with the brazilian central bank governor arminio fraga or discussing alternative approaches to bankruptcy law with indonesia s economic team or optimal debt durations with the mexican authorities i am consistently struck by the impact of the kind of research discussed at the aea meetings the future well being of the world s people in large part will depend on how the ongoing process of global integration works out this is a strong statement but one that is supported by the global economy s post world war i failure and its post world war ii success central to global integration is financial integration the flow of funds and of capital across international borders and as the events of the late 1920 s and early 1930 s remind us central to global disintegration can be international financial breakdowns today i want to reflect on the issue of global financial integration in light of the dramatic and largely unpredicted events of recent years it is perhaps a good time for reflection there has been enough repair that priority can shift from u s department of the treasury 1500 pennsylvania avenue washington dc 20005 this lecture reflects many things i have learned from experiences i have shared with colleagues in the united states government and governments around the world i thank brad delong marty feldstein stephanie flanders ken rogoff andrei shleifer and ted truman for useful comments and suggestions i am especially grateful to nouriel roubini and stephanie flanders for valuable discussions and assistance in the preparation of this lecture the usual disclaimer applies

economic obstacles to expanding intra african trade abstract the paper extends the gravity model to examine the impact of infrastructure availability economic policy and internal political tensions on intra african trade to highlight specific obstacles hampering such a trade bilateral trade between africa and developed countries is also analyzed the results show that besides traditional gravity variables poor infrastructure economic policy mismanagement and internal political tensions have a negative impact on trade among african countries except for political tensions the identified obstacles are specific to intra african trade since they have no impact on african trade with developed countries

on the efficiency of the european carbon market new evidence from phase ii i examine in the period 2008 2011 the efficiency of four carbon dioxide co2 emission allowance futures traded in the intercontinental exchange ice to this end i assess the profitability of trading strategies based on simple technical analysis rules and naive forecasts the results from 2010 onwards are consistent with weak market efficiency in turn this finding suggests that the european carbon market is gradually attaining a state of maturity

carbon trading thickness and market efficiency abstract this note tests for the efficient market hypothesis emh in the market for co 2 emission allowances in phase i and phase ii of the european union emissions trading scheme eu ets as usually is the case in emerging and non competitive markets such as the eu ets trading often not occurs on a frequent basis this has adverse implications for both the gains from permit trade as well as biases the emh tests variance ratio tests are employed to adjust for the thin trading effect the results indicate that phase i the trial and learning period was inefficient whereas the first period under phase ii shows signs of restoring market efficiency

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

hard or soft pegs choice of exchange rate regime and trade in africa summary this paper revisits the link between fixed exchange rate regimes and trade in the context of africa s exchange rate arrangements differentiating the effects of hard pegs currency unions from conventional soft pegs using a novel dataset of exchange rate regime classification the paper augments the gravity model of bilateral trade flows with measures of currency unions and conventional pegged arrangements and benchmarks africa s experience against the rest of the world we find that in both samples currency unions and pegs increase trade vis a vis more flexible exchange rate arrangements through channels in addition to reduced exchange rate volatility however the effect is almost twice as large for africa in addition the trade generating effect of pegs is at least as large for africa as that of currency unions suggesting that pegs could present a viable option perhaps an alternative to currency unions to promote trade in the region

does short term debt increase vulnerability to crisis evidence from the east asian financial crisis abstract does short term debt increase vulnerability to financial crisis or does short term debt reflect rather than cause the incipient crisis we study the role that short term debt played in the collapse of the east asian financial sector in 1997 1998 we alleviate concerns about the endogeneity of short term debt by using long term debt obligations that matured during the crisis we find that debt obligations issued at least three years before the crisis had a negative albeit sometimes insignificant effect on the probability of failure our results are consistent with the view that short term debt reflects rather than causes distress in financial institutions

measuring the maturity of carbon market in china an entropy based topsis approach abstract in this study we construct an evaluation index system in terms of three dimensions including internal external and interface factors we propose an entropy based topsis model to measure the maturity of carbon market the proposed model uses the entropy method to objectively weight the indicators and the topsis method to measure the maturity of carbon market taking china s seven pilot carbon markets from 2013 to 2017 as an example the empirical results are that the overall maturity of china s pilot carbon markets is relatively low for the sake of small market size low market effectiveness low market activeness and high price volatility moreover due to the difference in the quotas transaction volume market liquidity and market supporting facilities there are obvious differences in maturities among china s seven pilot carbon markets in 2017 the maturity of hubei market is the highest reaching 0 6146 the maturity of guangdong shenzhen beijing shanghai and tianjin reaches 0 6108 0 5022 0 4351 0 4267 and 0 3888 respectively the maturity of chongqing market is the only 0 3633 at the lowest level what s more from the perspective of maturity evolution trend hubei guangdong and shenzhen fluctuate upward from the market opening to 2017 and steadily rank in the top three shanghai and tianjin show a u shaped growth trend declining from 2013 to 2015 and continuing to rise from 2015 to 2017 beijing shows a fluctuating downward trend from 2013 to 2017 while ranking fourth chongqing ranks relatively low but it shows an escalating trend finally several targeted policy implications are put forward to enhance the maturities of carbon markets

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

globalization and the confidence game abstract we show that governments in developing countries have an incentive to play the confidence game wherein the need to win the confidence of the international capital market can actually prevent a country from following otherwise sensible policies and force it to follow policies that it would normally consider perverse this incentive arises because of a combination of a conformity bias and good news bias in governmental decision making in an open economy which results in inefficient outcomes which increases rather than decreases the threat of devaluation while institutions that encourage greater transparency and the public revelation of information may often mitigate this inefficiency on some occasions increased transparency may even exacerbate the inefficiency

bank run psychology abstract banks are inherently susceptible to panics and bank runs due to the problem of maturity mismatch resulting in both a stable equilibrium in which the bank survives and an unstable equilibrium in which a bank run occurs understanding equilibrium selection in this setting is extremely important for safeguarding financial stability in this paper one new potential factor that determines whether a bank runs gets triggered or not is experimentally studied namely the psychological state of the depositor prior to participating in an experimental bank run game subjects are either induced with fear sadness or happiness using an autobiographical emotion induction task the findings suggest that the presence of background fear significantly increases the likelihood of withdrawal and a subsequent bank run in addition women are shown to be significantly more likely to withdraw then men but only in the fear induction treatment

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

research on the efficiency of carbon trading market in china abstract in 2014 china proposed medium and long term low carbon development goals in china u s joint statement on climate change that the emission of carbon dioxide would reach its peak and the proportion of non fossil energy accounted for the primary energy consumption would increase to 20 in 2030 in order to achieve these goals the unified carbon emission trading system should be put into effect by 2017 the implementation of the unified carbon emission trading system depends on the effectiveness of the current carbon trading market in china on the basis of the effective market theory and fair game model the unit root test and the run test are developed to analyze the carbon emission market of four representative cities in china the results show that 1 the carbon trading market in china has only achieved weak efficiency while the semi strong efficiency and the strong efficiency have not been reached 2 with the expansion of the market scale the increase of trading volume the carbon trading market would converge from the state of inefficiency to weak form efficiency gradually and the carbon trading market in china shows signs of restoring market efficiency

currency crashes in emerging markets an empirical treatment we use a panel of annual data for over 100 developing countries from 1971 through 1992 to characterize currency crashes we define a currency crash as a large change of the nominal exchange rate that is also a substantial increase in the rate of change of nominal depreciation we examine the composition of the debt as well as its level and a variety of other macroeconomic factors external and foreign crashes tend to occur when output growth is low the growth of domestic credit is high and the level of foreign interest rates are high a low ratio of fdi to debt is consistently associated with a high likelihood of a crash

market efficiency in the european carbon markets in this paper we study the relationship between futures and spot prices in the european carbon markets from the cost of carry hypothesis the aim is to investigate the extent of efficiency market the three main european markets bluenext eex and ecx are analyzed during phase ii covering the period from march 13 2009 to january 17 2012 futures contracts are found to be cointegrated with spot prices and interest rates for several maturities in the three co2 markets results are similar when structural breaks are taken into account according to individual and joint tests the cost of carry model is rejected for all maturities and co2 markets implying that neither contract is priced according to the cost of carry model the absence of the cost of carry relationship can be interpreted as an indicator of market inefficiency and may bring arbitrage opportunities in the co2 market

dollars for sale exchange rate policy and inflation in africa abstract in africa the government is often the main provider of foreign exchange acquired through aid or via a nationalized mining sector although a parallel market is also usually active a policy of indexing the official exchange rate on the parallel one is destabilizing while a nominal anchor policy has the opposite effect using the case of nigeria these stylized facts are interpreted in the light of an analytical model with rational expectations the case of guinea is also presented as an example of where the nominal anchor policy has succeeded

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

a model of financial structure and financial fragility this paper presents an asymmetric information model of financial structure the model has two types of financial institutions banks and securities markets both of which can hold loans made to firms to finance investment projects the securities markets have lower costs but they have a lemons problem because the banks have better information the result is an equilibrium that can exhibit fragility in the sense that small parameter changes such as changes in the cost advantage of the securities market or the risk structure of loans can lead to discontinuous changes in interest rates asset prices and market structure

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

political extremism and economic activity abstract we study the effect of economic activity on the vote share of extremist political parties in europe using a model that addresses the prevalent endogeneity problem which is likely to have discouraged similar research we find that small fluctuations in income per capita have significant inverse effects on the vote share of far right parties our results explain the widespread success of such parties in entering european parliaments following the 2007 2008 crisis they also suggest that ceteris paribus far right parties on the margin of electoral thresholds run the risk of losing parliamentary representation in the face of a steadily recovering world economy

crisis costs and debtor discipline the efficacy of public policy in sovereign debt crises abstract recent debate on the reform of the international financial architecture has highlighted the potentially important role of the official sector in crisis management we examine how such public intervention in sovereign debt crises affects efficiency ex ante and ex post our results shed light on the scale of capital inflows and the implications for debtor country output of such a regime the efficacy of measures such as officially sanctioned stays on creditor litigation depend critically on the quality of public sector surveillance and the size of the costs of sovereign debt crises

lessons from the asian crisis abstract this paper provides an asymmetric information analysis of the recent east asian crisis it then outlines several lessons from this crisis first there is a strong rationale for an international lender of last resort second without appropriate conditionality for this lending the moral hazard created by operation of an international lender of last resort can promote financial instability third although capital flows did contribute to the crisis they are a symptom rather than an underlying cause of the crisis suggesting exchange controls are unlikely to be a useful strategy to avoid future crises fourth pegged exchange rate regimes are a dangerous strategy for emerging market countries and make financial crises more likely

redefining the role of the state an interview with introduction by brian snowdon professor joseph stiglitz is without question one of the world s leading economists in his extensive research he has made seminal contributions to the analysis of the economic consequences of incomplete information and uncertainty this work has greatly enhanced economists understanding of the welfare properties of markets and the sources of market failure his research has also contributed to the development of better microeconomic foundations for keynesian macroeconomic models most recently professor stiglitz has been heavily involved in controversial public policy debates relating to the east asian crisis problems of transition from communism to capitalism the limitations of the washington consensus and globalisation and development a common theme in all of these debates relates to the role of government and legitimate borders of the state in both developed and developing economies in this article interview professor stiglitz gives his views on these and several other important global issues

the benefits and costs of monetary union in southern africa a critical survey of the literature with the 14 members of the southern african development community sadc having set the objective of adopting a common currency for the year 2018 an expanding empirical literature has emerged evaluating the benefits and costs of a common currency area in southern africa this paper reviews that literature focusing on two categories of studies 1 those that assume that a country s characteristics are invariant to the adoption of a common currency and 2 those that assume that a monetary union alters an economy s structure resulting in trade creation and credibility gains the literature reviewed suggests that a relatively small group of countries typically including south africa satisfies the criteria necessary for monetary unification the literature also suggests that in a monetary union comprising all sadc countries and a regional central bank that sets monetary policy to reflect the average economic conditions e g fiscal balances in the region the potential losses i e higher inflation from giving up an existing credible national central bank a relevant consideration for south africa could outweigh any potential benefits of trade creation resulting from a common currency

firm specific information and the efficiency of investment abstract in the three year period following stock market liberalizations the growth rate of the typical firm s capital stock exceeds its pre liberalization mean by an average of 4 1 percentage points cross sectional changes in investment are significantly correlated with the signals about fundamentals embedded in the stock price changes that occur upon liberalization panel data estimations show that a 10 percentage point increase in a firm s expected future sales growth predicts a 2 9 to 3 5 percentage point increase in the growth rate of its capital stock country specific changes in the cost of capital drive changes in investment but firm specific changes in the cost of capital do not

effects of financial autarky and integration the case of the south africa embargo abstract the paper interprets the imposition in 1985 and removal in 1993 of the embargo on south africa as financial autarky and financial integration natural experiments and studies the effects on the economy the aggregate data indicate a decrease in the levels and growth rates of investment capital and output during the embargo period relative to the pre embargo and post embargo periods to further rationalize these findings we calibrate a neoclassical growth model to the economy during the transition to steady state we limit the country s ability to borrow for a period corresponding to the duration of the embargo the derived dynamics for investment capital and output support the findings of a positive negative link between financial integration isolation and economic growth

financial development financial liberalization and social capital abstractthe relationship between financial liberalization policies and financial development is controversial the impact of these policies differs greatly across countries in the literature the quality of formal institutions has been identified as an important source of this heterogeneity as countries with a weak institutional environment generally fail to benefit from financial liberalization using panel data covering 82 countries for the period 1973 2008 we find evidence that social capital may substitute for formal institutions as a prerequisite for effective financial liberalization policies in particular we find that during the post washington consensus period countries with a high prevailing level of social capital can ensure that financial liberalization positively influences financial development despite the poor quality of their formal institutions

financial liberalization and economic growth a meta analysis this study provides a systematic analysis of the empirical literature on the relationship between financial liberalization and economic growth by conducting a meta analysis based on 441 t statistics reported in 60 empirical studies we focus on explaining the heterogeneity of results in our sample in terms of study data and method specific characteristics although our findings indicate that on average there is a positive effect of financial liberalization on growth the significance of this effect is only weak moreover we find that most of the variables that may help explain the heterogeneity of results are insignificant there are two exceptions first studies carried out based on data from the 1970s on average find a statistically less significant relationship between financial liberalization policies and growth i e they report lower t statistics as compared to studies using data from the 1980s second studies controlling for the level of development of the financial system report lower t statistics for the relationship between liberalization and growth

does it pay to go to the corners an empirical evaluation of the bipolar view of exchange rate regimes abstract this paper provides the first empirical evidence for the controversial bipolar view which suggests that countries should move towards the two corner regimes my results show that compared to intermediate regimes the two corners are associated with significantly lower inflation

optimal contracts when enforcement is a decision variable this paper analyzes choice theoretic costly enforcement in an intertemporal contracting model with a differentially informed investor and entrepreneur an intertemporal contract is modeled as a mechanism in which there is limited commitment to payment and enforcement decisions the goal of the analysis is to characterize the effect of choice theoretic costly enforcement on the structure of optimal contracts the paper shows that simple debt is the optimal contract when commitment is limited and costly enforcement is a decision variable theorem 1 in contrast stochastic contracts are optimal when agents can commit to the ex ante optimal decisions theorem 2 the paper also shows that the costly state verification model can be viewed as a reduced form of an enforcement model in which agents choose payments and strategies as part of a perfect bayesian nash equilibrium

the international monetary fund in a time of crisis a review of stanley fischer s imf essays from a time of crisis the international financial system stabilization and development stanley fischer was deputy managing director of the imf from 1994 to 2001 and perhaps more than any other individual he personifies the international rapid response to financial crises in the 1990s this book is a collection of essays written during his tenure at the imf taken together the essays represent the strongest and most logical defense of imf initiatives in the 1990s in print my review essay comprises six parts in parts 2 through 4 i provide an overview of fischer s arguments in three central areas of contention stabilization policy the impact of imf programs on poverty and the imf s anticipation of and response to international financial crisis i then compare fischer s arguments to those raised by the imf s critics during that period the controversial issues of these parts can be resolved only through empirical investigation but on the issues of greatest importance from the financial crises of the 1990s both fischer and the imf s critics make logically consistent arguments with little empirical support in part 5 i review the recent empirical literature to illuminate what evidence has been found in support of or counter to the assertions of fischer and the imf s critics part 6 provides conclusions and suggestions for follow on empirical research

market concentration and the likelihood of financial crises abstract according to theory market concentration affects the likelihood of a financial crisis in different ways the concentration stability and the concentration fragility hypotheses suggest opposing effects operating through specific channels using data of 160 countries for the period 1970 2009 this paper empirically tests these indirect effects of financial market structure we set up a simultaneous system in order to jointly estimate financial stability and the relevant channel variables as endogenous variables our findings provide support for the assumption of channel effects in general and both the concentration stability and the concentration fragility hypothesis in particular the effects are found to vary between high and low income countries

how to improve the market efficiency of carbon trading a perspective of china abstract emissions trading scheme ets is one of the effective measures to realize energy conservation and emission reduction in order to set up a nationwide carbon emissions trading mechanism seven ets pilots have been launched in china firstly based on empirical investigation and research of seven pilots this paper analyzed the market efficiency of ets pilots from four aspects carbon price trading volume market liquidity and information transparency the result showed that the market efficiency of ets pilots is not satisfactory in spite of the fact that system designs of ets have achieved preliminary result then the reason for low market efficiency of ets pilots was discussed from some factors such as institutional arrangements market participants the supply and demand etc finally this paper puts forward some policy suggestions to improve the market efficiency of china s carbon trading market

economic development under alternative trade regimes how does openness affect economic development this question is answered in the context of a dynamic general equilibrium model of the world economy where countries have technological differences that are both sector neutral and specific to the investment goods sector relative to a benchmark case of trade in credit markets only consider i a complete restriction of trade and ii a full liberalization of trade the first change decreases the cross sectional dispersion of incomes only slightly and produces a relatively small welfare loss the second change instead decreases dispersion by a significant amount and produces a very large welfare gain

a literature survey on proposed african monetary unions this study provides a survey of recent advances in the literature on proposed african monetary unions the survey comprises about 60 empirical papers published during the past fifteen years four main strands are discussed individually and collectively notably the proposed west african monetary zone wamz east african monetary union eamu southern african monetary union samu and african monetary union amu we observe a number of issues with establishing the feasibility and or desirability of potential monetary unions inter alia variations in choice of variables empirical strategies sampled countries and considered periodicities we address this ambiguity by reviewing studies with scenarios that are consistent with hegelian dialectics and establish selective expansion as the predominant mode of monetary integration some proponents make cases for strong pegs and institutions as viable alternatives to currency unions using cluster analysis disaggregating panels into sub samples and distinguishing shocks from responses in the examination of business cycle synchronisation provide more subtle policy implications we caution that for inquiries using the same theoretical underpinnings variables and methods just by modifying the scope context and periodicity may only contribute to increasing the number of conflicting findings authors should place more emphasis on new perspectives and approaches based on caveats of and lessons from the european monetary union emu and cfa zones

new directions for modelling strategic behavior game theoretic models of communication coordination and cooperation in economic relationships author s crawford vp abstract in this paper i discuss the state of progress in applications of game theory in economics and try to identify possible future developments that are likely to yield further progress to keep the topic manageable i focus on a canonical economic problem that is inherently game theoretic that of fostering efficient coordination and cooperation in relationships with particular attention to the role of communication i begin with an overview of noncooperative game theory s principal model of behavior nash equilibrium i next discuss the alternative thinking and learning rationales for how real world actors might reach equilibrium decisions i then review how nash equilibrium has been used to model coordination communication and cooperation in relationships and discuss possible developments

capital account liberalization financial depth and economic growth abstract we show a statistically significant and economically relevant effect of open capital accounts on financial depth and economic growth in a cross section of countries over the periods 1986 1995 and 1976 1995 countries having open capital accounts had a significantly greater increase in financial depth and over the 20 year period greater economic growth these results however are largely driven by the developed countries included in the sample the observed failure of capital account liberalization to promote financial deepening among developing countries suggests potentially important policy implications concerning the desirability of opening up the capital account
