deep habits price rigidities and the consumption response to government spending this paper inspects the deep habits mechanism originally used by ravn schmitt grohe and uribe 2006 to generate the positive comovement of public and private consumption observed in many var studies in their set up the price elasticity of demand is pro cyclical and it is optimal for the firm to lower the mark up while expanding production after the fiscal shock raising the demand for labor and the real wage consequently agents substitute consumption for leisure and overcome the negative wealth effect of the fiscal expansion here we show that increasing price stickiness reduces the impact of the fiscal shock on the real wage and hinders the rise of consumption if the degree of price stickiness is high enough consumption is crowded out this is in contrast to the role of price rigidities in the standard new keynesian model where they weaken the crowding out of consumption

does economic recession reduce material use empirical evidence based on 157 economies worldwide abstract the research on economic recession has been more focused on the interactions between macroeconomic and financial variables however whether material use has been affected during the recession period has remained under explored in order to fill up this gap this study investigates the relationship between material use and economic recession as well as other socio economic drivers by using the material flow analysis and the system generalized method of moments for 157 economies worldwide during 1980 2011 results show that economic recession poses significant and negative impact on domestic material consumption at 1 level illustrating its role as a determinant factor on material mitigation by dividing the research sample into extractive and non extractive economies as well as high mid and low income groups we again confirmed the significant negative correlations as expected no significant sign is found between recession and physical trade balance besides other drivers such as population gross domestic production gdp per capita and technological variables also exert marked effects at different situations this research work provides an empirical study on how recession and other factors affect material use at various scenarios which have essential implications for understanding material flow dynamics in different economic cycles

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

persistent government spending and fiscal multipliers the investment channel this paper inspects the mechanism shaping government spending multipliers in various smallscale dsge setups with endogenous labor supply and capital accumulation we analytically characterize the short run investment multiplier which in equilibrium can be either positive or negative the investment multiplier increases with the persistence of the exogenous government spending process the response of investment to government spending shocks strongly affects short run multipliers on output and consumption

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

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

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

the speculative attack on the peso and the real exchange rate argentina 1979 1981 abstract this article applies a speculative attack model to argentina during its pre announced exchange rate system from january 1 1979 to june 30 1981 the model attempts to verify a rule whereby if domestic credit growth exceeds the rate of currency depreciation two things occur first the domestic price of non traded goods rises relative to the price of traded goods second foreign reserves decline until a point when a sudden speculative attack depletes remaining reserves causes a precipitous fall in the relative price of non tradables and forces the country onto a floating exchange rate regime in some important respects the model captures the argentinian experience yet in other respects if fails to do so

crises and exchange rate regimes time to break down the bipolar view we revisit the link between crises and exchange rate regimes err using a panel of 90 developed and developing countries over the period 1980 2009 we find that corner err are not more prone to crises compared to intermediate err this finding holds for different types of crises banking currency and debt and is robust to a wide set of alternative specifications consequently we clearly break down the traditional bipolar view countries that aim at preventing crisis episodes should focus less on the choice of the err and instead implement sound structural macroeconomic policies

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

new keynesian models durable goods and collateral constraints abstract econometric evidence suggests that in response to monetary policy shocks durable and non durable spending co move positively and durable spending exhibits a much larger sensitivity to the shocks a standard two sector new keynesian model with perfect financial markets is at odds with these facts the introduction of a borrowing constraint where durables play the role of collateral assets helps in reconciling the model with the empirical evidence

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

is the housing market blind to religion a perceived substitutability approach to homophily and social integration housing markets are unlikely to be impervious to the preferences and prejudices associated with urban segregation for example two neighbourhoods with very different religious attributes are unlikely to be perceived as close substitutes by homebuyers that have a strong preference for neighbours of a particular religion this paper offers a new framework for the conception and measurement of social integration defined in terms of perceived homophily homophily is the tendency for links to form between similar nodes in a network and we can think of perceived homophily as the tendency for any pair of neighbourhoods to be considered by the housing market to be close substitutes textbook economic theory suggests that we should expect the degree of perceived substitutability to affect cross price elasticities these can be measured empirically to reveal discontinuities in the network of perceived substitutability of different housing locations applying homophily coefficients to substitutability measures allows us to estimate perceived religious homophily between neighbourhoods the approach can be applied to any city or region that has geocoded house transactions and socio demographic data we illustrate the method using data on glasgow and find strong evidence of religious homophily this suggests an underlying lack of social integration cohesion and implies that the glaswegian housing market is by no means blind to religion

government spending shocks and rule of thumb consumers with steady state inequality in the body of literature concerning fiscal policy a central result is that government spending might stimulate private consumption because only some households save while others spend their entire income each period although such heterogeneity naturally causes inequality this complication is commonly avoided by assuming that transfers redistribute steady state wealth i show that this steady state assumption drives short run results without redistribution the equilibrium is indeterminate and the labor market structure that is imposed to support the expansive result is theoretically inconsistent on a more positive note i propose a labor market formulation under which the expansive effects of government spending might arise

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

housing submarkets and the lattice of substitution this paper aims to stimulate interest in the early micro economic conceptualisation of housing submarkets proposed by rapkin and grigsby which defined market areas in terms of dwelling substitutability three key questions need to be addressed if a return to the rapkin grigsby approach is to be achievable and worthwhile first what are the practical benefits the paper highlights a range of potential research applications that would benefit from the substitutability approach secondly in what way are existing approaches likely to be inadequate for demarcating substitutability based submarkets four criteria are proposed for assessing submarket estimation methods which existing approaches fail to satisfy thirdly what are the prospects for developing a substitutability metric that will make the rapkin grigsby definition empirically feasible a new measure is proposed based on the cross price elasticity of price cpep which is illustrated using data for glasgow scotland

rule of thumb consumers productivity and hours in this paper we study the transmission mechanism of productivity shocks in a model with rule of thumb consumers in the literature this nancial friction has been studied only with reference to scal shocks we show that the presence of rule of thumb consumers is also very helpful in accounting for recent empirical evidence on productivity shocks rule of thumb agents together with nominal and real rigidities play an important role in reproducing the negative response of hours and the delayed responses of output and

would protectionism defuse global imbalances and spur economic activity a scenario analysis abstract in the evolving debate and analysis of global imbalances a commonly overlooked issue pertains to rising protectionism this paper attempts to fill that gap examining the macroeconomic implications of trade policy changes through the lens of a dynamic general equilibrium model of the world economy encompassing four regional blocs simulation exercises are carried out to consider the imposition of uniform and discriminatory tariffs on trading partners as well as the case of tariff retaliation we also discuss a scenario in which a globalization backlash lowers the degree of competition in import competing sectors and compare the implications of higher markups in the product and labor markets

monetary policy rules macroeconomic stability and inflation a view from the trenches i estimate a forward looking monetary policy reaction function for the federal reserve for the periods before and after paul volcker s appointment as chairman in 1979 using information that was available to the fomc in real time from 1966 to 1995 the results suggest broad similarities in policy and point to a forward looking approach to policy consistent with a strong reaction to inflation forecasts during both periods this contradicts the hypothesis based on analysis with ex post constructed data that the instability of the great inflation was the result of weak fomc policy responses to expected inflation a difference is that prior to volcker s appointment policy was too activist in reacting to perceived output gaps that retrospectively proved overambitious drawing on contemporaneous accounts of fomc policy i discuss the implications of the findings for alternative explanations of the great inflation and the improvement in macroeconomic stability since then

downward nominal wage rigidity and state dependent government spending multipliers abstract despite much empirical evidence on business cycle dependent government spending multipliers the theoretical channels underlying such results are uncertain in an environment with involuntary unemployment this paper shows that downward nominal wage rigidity which arises only in recessions can generate business cycle dependent government spending multipliers in line with keynesian views a demand stimulus reduces unemployment in recessions and may not drive up inflation and wages as in expansions thus the positive income effects from reduced unemployment and weaker crowding out effects from a smaller increase in the real interest rate enhance the expansionary spending effects in recessions the theoretical implications are largely consistent with existing empirical evidence on business cycle dependent government spending effects on key macroeconomic variables

financial fragility and distress propagation in a network of regions we investigate how the financial fragility in the real economy is affected by the average level of interdependence among agents across different regions of the economy to this end we develop a parsimonious agent based model of firms and banks organized in geographic regions the model is built on the framework of an existing class of models for business fluctuations the goal of our exercise is to clarify the effect on systemic failures of the interplay between network interconnectedness and financial acceleration in particular we investigate the probability of individual and systemic failures with varying levels of interconnectedness we find that in the absence of financial acceleration connectivity makes the system more resilient in contrast in the presence of financial acceleration the probability of both individual and systemic failures are minimized at intermediate level of diversification

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

measuring the impact of fiscal policy in the face of anticipation a structural var approach empirical estimates of the impact of government spending shocks disagree on central issues such as the size of output multipliers and the responses of consumption and the real wage one explanation for the disagreement is that fiscal shocks are often anticipated due to misspecification of the information set anticipation effects may invalidate svar estimates of impulse responses we use economic theory to derive a fiscal svar estimator that is applicable when fiscal shocks are anticipated we study its properties and apply it to us data we fail to find evidence that anticipation effects overturn the existing findings from the fiscal svar literature despite years of intensive research the empirical literature on fiscal policy has yet to reach consensus on the macroeconomic impact of fiscal policy shocks disagreements concern central issues such as the size of output multipliers and the impact of government spending shocks on consumption and the real wage clearly such level of disagreement constrains our ability to give simple guidelines for the operation of one of the most important stabilisation policies a key empirical obstacle is the measurement of innovations to fiscal policy one strand of the literature employs structural vector autoregressive svar methods and achieves identification based on the presence of decision lags or sign restrictions

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 effect of government spending on private consumption a puzzle the empirical finding that cyclical changes in government spending tend to be associated with positive responses of private consumption has been interpreted as a challenge for representative agent intertemporal optimizing theories which usually imply that the negative wealth effect of higher fiscal spending reduces the households consumption and leisure the present paper shows that the evidence can be explained by a standard real business cycle type model with a nonadditively separable utility function and a small intertemporal consumption elasticity higher fiscal spending can raise consumption and lower investment as in the data the nonseparable utility model is shown to imply the same consumption euler equation as a model with rule of thumb consumers who mechanically spend their income

clearing up the fiscal multiplier morass bayesian prior predictive analysis of five nested dsge models suggests that model specifications and prior distributions tightly circumscribe the range of possible government spending multipliers multipliers are decomposed into wealth and substitution effects yielding uniform comparisons across models by constraining the multiplier to tight ranges model and prior selections bias results revealing less about fiscal effects in data than about the lenses through which researchers choose to interpret data when monetary policy actively targets inflation output multipliers can exceed one but investment multipliers are likely to be negative passive monetary policy produces consistently strong multipliers for output consumption and investment

why does private consumption rise after a government spending shock recent empirical evidence suggests that private consumption is crowded in by government spending this outcome violates existing macroeconomic theory according to which the negative wealth effect brought about by a rise in public expenditure should decrease consumption

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

impact of financial crises on poverty in developing world an empirical approach in this paper we adopt a cross country perspective to analyze the short term effects of currency banking and debt crises on poverty we employ multivariate fixed effects panel data analysis in order to examine whether and to what extent different types of financial crises impact the poverty headcount ratio and the poverty gap as measured by the world bank our findings suggest that out of the three categories of financial crises we identify it is currency crises that most significantly exacerbate both the incidence and depth of poverty in the short run we find evidence that banking crises are associated with an increase in the depth of poverty but not the incidence however this effect tends to be short lived while our analysis shows no direct effect of sovereign debt crises on short term poverty

who recovers first banking crises resolution in developing countries this article evaluates conditions that facilitate banking crises resolution using data from 67 developing countries from 1980 to 1995 in particular the author examines explanatory variables under three categories external macroeconomic constraints the role of the international monetary fund imf and domestic political conditions the principal results of the analyses are twofold first imf credits decrease the probability of resolving banking crises this result holds controlling for potentially confounding variables and in a test for endogeneity second the decisiveness of a political regime significantly influences the probability of emerging from systemic distress specifically in cases of moderate banking distress decisiveness facilitates resolution of crisis but during periods of severe crises less decisive governments i e governments constrained by accountability groups are likely to recover more quickly than are those with less constrained executives

fiscal stimulus and the role of wage rigidity abstract in this paper we study the impact of an expansion in public spending in an economy characterized by limited asset market participation and sticky wages the flexible wage version of the model implies strong expansionary effects on output and consumption but also a counterfactual increase in real wages the introduction of sticky wages besides being a realistic addition solves this problem and preserves the expansionary effects on output and consumption moreover once we introduce segmentation in the labor market sticky wages are even essential to obtain expansionary effects

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

rule of thumb consumers meet sticky wages it has been argued that rule of thumb consumers substantially alter the determinacy properties of simple interest rate rules and the dynamics of an otherwise standard new keynesian model in this paper we show that nominal wage stickiness helps re establishing standard results key findings are that wage stickiness i affects the shape of determinacy regions in the parameters space restoring the relevance of the taylor principle for the conduct of monetary policy ii implies that a rise in consumption in response to an innovation in government spending is not a robust feature of the model

the general equilibrium effects of fiscal policy estimates for the euro area abstract this paper describes a dynamic stochastic general equilibrium model featuring a fraction of non ricardian agents in order to estimate the effects of fiscal policy in the euro area the model takes into account distortionary taxation on labor and capital income and on consumption while expenditures are broken down into purchases of goods and services compensation of public employees and transfers to households a newly computed quarterly data set of fiscal variables is used our results point to the prevalence of mild keynesian effects of public expenditures in particular although innovations in fiscal policy variables tend to be rather persistent government purchases of goods and services and compensations for public employees have small and short lived expansionary effects on private consumption while innovations in transfers to households show a slightly more sizeable and lasting effect the effects are more significant on the revenue side decreases in labor income and consumption tax rates have sizeable effects on consumption and output while a reduction in capital income tax favors investment and output in the medium run finally our estimates suggest that fiscal policy variables contribute little to the cyclical variability of the main macro variables

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

a measure of segregation based on social interactions we develop an index of segregation based on two premises 1 a measure of segregation should disaggregate to the level of individuals and 2 an individual is more segregated the more segregated are the agents with whom she interacts we present an index that satisfies 1 and 2 and that is based on agents social interactions the extent to which blacks interact with blacks whites with whites etc we use the index to measure school and residential segregation using detailed data on friendship networks we calculate levels of within school racial segregation in a sample of u s schools we also calculate residential segregation across major u s cities using block level data from the 2000 u s census

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

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

currency crises capital account liberalization and selection bias are countries with unregulated capital flows more vulnerable to currency crises efforts to answer this question properly must control for self selection bias since countries with liberalized capital accounts may also have more sound economic policies and institutions that make them less likely to experience crises we employ a matching and propensity score methodology to address this issue in a panel analysis of developing countries our results suggest that after controlling for sample selection bias countries with liberalized capital accounts experience a lower likelihood of currency crises that is when two countries have the same likelihood of allowing free movement of capital based on historical evidence and a very similar set of economic and political characteristics and one country imposes controls and the other does not the country without controls has a lower likelihood of experiencing a currency crisis this result is at odds with the conventional wisdom and suggests that the benefits of capital market liberalization for external stability are substantial

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

money prices interest rates and the business cycle the mechanisms governing the relationship of money prices and interest rates to the business cycle are the most studied and most disputed topics in macroeconomics in this paper we first document key empirical aspects of this relationship we then ask how well three benchmark rational expectations macroeconomic models a real business cycle model a sticky price model and a liquidity effect model account for these central facts while the models have diverse successses and failures none can account for the fact that real and nom inal interest rates are inverted leading indicators of real economic activity that is none of the models captures the post war u s business cycle fact that a high real or nominal interest rate in the current quarter predicts a low level of real economic activity two to four quarters in the future i introduction the positive correlation of monetary aggregates and real economic activity over the course of many business cycles is a key empirical fact about the u s economy indeed the dynamic dimension of this covariation is so strong and stable that a monetary variable has long been included in the commerce department s index of leading economic indica tors while this pattern of cyclical comovement is widely agreed upon its interpretation is not some macroeconomists view money as purely passive with a positive response to varying levels of economic activity producing the positive correlation others view changes in the quantity of money as an important perhaps dominant source of economic fluctua tions frequently the real effects of monetary changes are suggested to arise from frictions in commodity labor or financial markets in economic theories that describe the influence of these frictions the transmission mechanism from monetary changes to real activity is typically viewed as involving interest rates and the price level the primary goal of this paper is to evaluate three models that explain the link between money prices interest rates and the business cycle we do this in three steps first we docu ment the cyclical behavior of these variables in the united states over the postwar period second we construct three quantitative rational expectations models of macroeconomic activity i a real business cycle model with endogenous money ii a model of commodity market frictions with mon etary non neutralities arising from gradual adjustment of goods prices and iii a model of financial market frictions with monetary non neutralities arising from gradual adjust ments of portfolios finally we compare the models predic tion for the business cycle behavior of money prices and interest rates with the data in exploring the predictions of these models we take the stock of money to be one of several exogenous variables in the system all of our models are capable of generating a forecasting role for money relative to real economic activity similar to that found in the u s data in the real business model monetary changes can forecast real activity because productivity is related to many underlying sources of shocks and because these real shocks also affect the money stock in the models with sticky prices and liquidity effects short hand names for the models with frictions in the com modity and financial markets monetary changes have an additional direct positive effect on aggregate output the outline of the paper is as follows section ii describes the data and documents its business cycle characteristics section iii outlines the three macroeconomic models and develops the particular quantitative versions of the models used in our analysis our main empirical results are pre sented in section iv and section v summarizes our results and concludes

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

do government purchases affect unemployment we estimate the effect of government purchases on unemployment in 20 oecd countries for the period 1980 2007 an increase in government purchases equal to one percent of gdp is found to reduce unemployment by about 0 3 percentage points in the same year the effect is greater and more persistent under less employment friendly labour market institutions and greater and more persistent under a fixed exchange rate regime than under a floating regime the effect is also greater in downturns than in booms the effect on unemployment reflects a corresponding positive effect of increased government purchases on the employment to population rate this article is protected by copyright all rights reserved

the savers spenders theory of fiscal policy the macroeconomic analysis of fiscal policy is usually based on one of two canonical models the barro ramsey model of infinitely lived families or the diamond samuelson model of overlapping generations this paper argues that neither model is satisfactory and suggests an alternative in the proposed model some consumers plan ahead for themselves and their descendants while others live paycheck to paycheck this model is easier to reconcile with the essential facts about consumer behavior and wealth accumulation and it yields some new and surprising conclusions about fiscal policy

what are the effects of fiscal policy shocks we propose and apply a new approach for analyzing the effects of fiscal policy using vector autoregressions specifically we use sign restrictions to identify a government revenue shock as well as a government spending shock while controlling for a generic business cycle shock and a monetary policy shock we explicitly allow for the possibility of announcement effects i e that a current fiscal policy shock changes fiscal policy variables in the future but not at present we construct the impulse responses to three linear combinations of these fiscal shocks corresponding to the three scenarios of deficit spending deficit financed tax cuts and a balanced budget spending expansion we apply the method to us quarterly data from 1955 to 2000 we find that deficit financed tax cuts work best among these three scenarios to improve gdp with a maximal present value multiplier of five dollars of total additional gdp per each dollar of the total cut in government revenue 5 years after the shock copyright 2009 john wiley sons ltd

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

how strong is the macroeconomic case for downward real wage rigidity we explore the existence of downward real wage rigidity drwr at the industry level based on data from 19 oecd countries for the period 1973 1999 the results show that drwr compresses the distributions of industry wage changes overall as well as for specific geographical regions and time periods but there are not many real wage cuts that are prevented more important however drwr attenuates larger real wage cuts thus leading to higher real wages there is stronger evidence for downward nominal wage rigidity than for drwr real wage cuts are less prevalent in countries with strict employment protection legislation and high union density

rethinking the role of fiscal policy as recently as two years ago there was a widespread consensus among economists that fiscal policy is not useful as a countercyclical instrument now governments in washington and around the world are developing massive fiscal stimulus packages supported by a wide range of economists in universities governments and businesses why has this change occurred what are the principles for designing a potentially useful fiscal stimulus and what will happen if the current fiscal stimulus fails this abstract was borrowed from another version of this item

endogenous money or sticky prices abstract what explains the correlations between nominal and real variables in the postwar us data are these correlations indicative of significant nominal rigidity or do they simply reflect the particular way that monetary policymakers react to developments in the real economy to answer these questions this paper uses maximum likelihood to estimate a model of endogenous money this model allows but does not require nominal prices to be sticky the results show that nominal price rigidity over and above endogenous money plays a role in accounting for key features of the data

fiscal policy in the new neoclassical synthesis we analytically derive the cyclical effects of fiscal policy shocks in a new neoclassical synthesis model price stickiness has the consequence that a rise in government demand affects labor demand while at the same time the usual wealth effect boosts labor supply the strength of the demand effect depends on the response of the real interest rate governed by the monetary policy regime when the central bank controls money growth fiscal expansions are deflationary and might even be contractionary whereas output wages and inflation can increase when the rise in the real interest rate is dampened by an interest rate rule however price stickiness alone is not sufficient to explain a rise in consumption as predicted by keynesian theory

the new keynesian cross abstract the new keynesian nk cross is a graphical and analytical apparatus for heterogeneous agent hank models expressing key aggregate demand objects mpc and multipliers as functions of heterogeneity parameters it affords analytical insights into monetary fiscal and forward guidance multipliers and replicates the aggregate implications of quantitative hank the key parameter the constrained agents income elasticity to aggregate income depends on fiscal redistribution when it is larger smaller than one the effects of policies and shocks are amplified dampened with uninsurable idiosyncratic uncertainty this translates intertemporally through compounding discounting in the aggregate euler equation into further amplification dampening of future shocks

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

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

propagation mechanisms for government spending shocks a bayesian comparison the inability of a simple real business cycle model to predict a rise in consumption in response to increased government expenditures observed in many empirical studies has stimulated the development of alternative theories of government spending shocks using the bayesian approach we evaluate the quantitative performance of five extant models and find that neither of the considered transmission mechanisms for government spending helps improve the fit of the baseline model moreover we find that consumption decreases in all estimated models in response to a rise in government spending

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

exchange market mayhem the antecedents and aftermath of speculative attacks exchange market mayhem the antecedents and aftermath of speculative attacks this paper evaluates the causes and consequences of episodes of turbulence in foreign exchange markets using data from 1959 through 1993 for twenty oecd countries we consider the antecedents and aftermath of devaluations and revaluations flotations fixings and speculative attacks which may not be successful we find that realignments of fixed exchange rates are alike devaluations are preceded by political instability budget and current account deficits and fast growth of money and prices revaluations are mirror images of devaluations speculative attacks resemble devaluations but money growth and inflation are more endemic and there is no last minute attempt to tighten monetary policy in contrast few consistent correlations link regime transitions like flotations or fixings to macroeconomic or political variables transitions between exchange rate regimes are largely idiosyncratic and are neither consistently provoked ex ante by systematic imbalances nor typically justified ex post by subsequent changes in policy we conclude that there are no clear early warning signals of many speculative attacks and no easy solutions for policy makers barry eichengreen andrew k rose and charles wyplosz

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

arresting banking panics federal reserve liquidity provision and the forgotten panic of 1929 scholars differ on whether central bank intervention mitigates banking panics in april 1929 a fruit fly infestation in florida forced the u s government to quarantine fruit shipments from the state and destroy infested groves in july depositors panicked in tampa and surrounding cities the federal reserve bank of atlanta rushed currency to member banks beset by runs we show that this intervention arrested the panic and estimate that bank failures would have been twice as high without the federal reserve s intervention our results suggest that similar interventions may have reduced bank failures during the great depression

valuation effect of capital account liberalization evidence from the chinese stock market this paper examines the valuation effect of capital account liberalization using an event study approach and the policy announcement for rmb qualified foreign institutional investors short for rqfii as the event date we find that overall the stock market responded positively to the capital account liberalization announcement in addition we provide some heterogeneity that firms with more stringent financing constraints earn higher returns than their counterparts finally existing local institutions play an important role in determining announcement returns

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

leaning against windy bank lending using a dynamic stochastic general equilibrium model with banking this paper first provides evidence that during the great moderation monetary policy leaned against the wind blowing from the loan market in the us it then shows that the extent to which this occurred delivers a small welfare loss relative to the optimised simple interest rate rule that features only a response to inflation the source of business cycle fluctuations is crucial for the optimality of a leaning against the wind policy in fact the pro cyclical nature of lending creates a trade o between inflation and financial stabilisation when supply shocks are prevalent

new keynesian versus old keynesian government spending multipliers renewed interest in fiscal policy has increased the use of quantitative models to evaluate policy because of modelling uncertainty it is essential that policy evaluations be robust to alternative assumptions we find that models currently being used in practice to evaluate fiscal policy stimulus proposals are not robust government spending multipliers in an alternative empirically estimated and widely cited new keynesian model are much smaller than in these old keynesian models the estimated stimulus is extremely small with gdp and employment effects only one sixth as large and with private sector employment impacts likely to be even smaller we investigate the sensitivity of our findings with regard to the response of monetary policy the zero bound on nominal interest rates and the inclusion of an empirically relevant degree of rule of thumb behaviour in the new keynesian model in addition we relate our findings using estimated structural macroeconomic models to the recent literature using reduced form regression techniques

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
