demand for money in open economies abstract the demand for real cash balances deduced from an underlying portfolio model of the financial market is shown to depend upon domestic variables and foreign monetary developments the model is estimated using quarterly postwar data for canada germany uk and us there is clear evidence that demand for money is affected not only by changes in domestic variables such as permanent income domestic interest rate and price expectations but also by fluctuations in exchange rate expectations and foreign interest rates the conclusion that domestic monetary policy is fairly ineffective and domestic financial markets are highly vulnerable to changes in foreign financial and monetary developments need to be modified in light of the results presented in this paper

efficient mechanisms for bilateral trading we consider bargaining problems between one buyer and one seller for a single object the seller s valuation and the buyer s valuation for the object are assumed to be independent random variables and each individual s valuation is unknown to the other we characterize the set of allocation mechanisms that are bayesian incentive compatible and individually rational and show the general impossibility of ex post efficient mechanisms without outside subsidies for a wide class of problems we show how to compute mechanisms that maximize expected total gains from trade and mechanisms that can maximize a broker s expected profit journal of economic literature classification number 026

taxes and capital structure understanding firms savings abstract the u s non financial corporate sector became a net lender to the rest of the economy in the early 2000s with close to half of all publicly traded firms holding financial assets in excess of their debt liabilities we develop a simple dynamic model of debt and equity financing where firms strive to accumulate financial assets even though debt is fiscally advantageous relative to equity moreover firms find it optimal to fund additional financial asset holdings through equity revenues the calibrated model matches well the distribution of public firms balance sheets during the 2000s and correctly predicts which firms are net savers

optimal democratic mechanisms for taxation and public good provision abstract we study the interdependence of optimal tax and expenditure policies an optimal policy requires that information on preferences is made available we first study this problem from a general mechanism design perspective and show that efficiency is possible only if the individuals who decide on public good provision face an own incentive scheme that differs from the tax system we then study democratic mechanisms with the property that tax payers vote over public goods under such a mechanism efficiency cannot be reached and welfare from public good provision declines as the inequality between rich and poor individuals increases

boom and bust cycles external imbalances and the real exchange rate when the current account balance and net capital outflows do not exactly offset each other international payment flows arise payment flows into a country push the real exchange rate up payment outflows push it down this article uses a model of optimal consumption and portfolio choice to determine the factors that drive international payment flows during boom and bust cycles it shows that during such episodes capital inflows first exceed the deficit on current account strengthening the currency later on when the return on domestic capital reverts to its normal level the current account recovers yet the overall decline of the net foreign asset position provokes a fall of the real exchange rate even below its initial level case studies of countries experiencing rapid economic expansions followed by economic and financial meltdowns confirm the article s theoretical predictions

individually rational budget balanced mechanisms and allocation of surplus abstract we investigate the issue of implementation via individually rational ex post budget balanced bayesian mechanisms we show that all decision rules generating a nonnegative expected social surplus are implementable via such mechanisms if and only if the probability distribution of the agents type profiles satisfies two conditions the well known condition of cremer and mclean 1988 full extraction of the surplus in bayesian and dominant strategy auctions econometrica 56 1247 1257 and the identifiability condition introduced in this paper we also show that these conditions are necessary for ex post efficiency to be attainable with budget balance and individual rationality and that the expected social surplus in these mechanisms can be distributed in any desirable way lastly we demonstrate that like cremer mclean condition the identifiability condition is generic if there are at least three agents

how debt markets have malfunctioned in the crisis the financial crisis that began in 2007 is especially a crisis in debt markets a full understanding of what happened in the financial crisis requires investigation into the plumbing of debt markets during a financial crisis when funds often cannot be raised easily or quickly the fundamental values for certain assets can become separated for a time from market prices with consequences that can echo into the real economy this article will explain in concrete ways how debt markets can malfunction with deleterious consequences for the real economy after a quick overview of debt markets i discuss three areas that are crucial in all debt markets decisions risk capital and risk aversion repo financing and haircuts and counterparty risk in each of these areas feedback effects can arise so that less liquidity and a higher cost for finance can reinforce each other in a contagious spiral i will document the remarkable rise in the premium that investors placed on liquidity during the crisis next i will show how these issues caused debt markets to break down indeed fundamental values and market values seemed to diverge across several markets and products that were far removed from the toxic subprime mortgage assets at the root of the crisis finally i will discuss briefly four steps that the federal reserve took to ease the crisis and how each was geared to a specific systemic fault that arose during the crisis

simple contracts renegotiation under asymmetric information and the hold up problem abstract in this article it is demonstrated that voluntary bargaining over a collective decision under asymmetric information may well lead to ex post efficiency if the default decision is non trivial it is argued that the default decision may be interpreted as a simple contract that the parties have written ex ante this result is used in order to show that simple unconditional contracts which are renegotiated may allow the hold up problem to be solved even if the parties valuations are private information

the interaction of monetary and macroprudential policies i analyze a new keynesian dynamic stochastic general equilibrium dsge model where the financing of productive investment is affected by a moral hazard problem i solve for jointly ramsey optimal monetary and macroprudential policies i find that when a financial friction is present in addition to the standard nominal friction the optimal policy can replicate the first best allocation if the social planner can conduct both monetary and macroprudential policy using monetary policy alone is not enough a policy trade off between stabilizing inflation and output gap emerges when policy follows simple rules the source of fluctuations is relevant for the choice of the appropriate policy mix

lending booms latin america and the world recent theories of crisis put lending booms at the root of financial collapses yet lending booms may be a natural consequence of economic development and fluctuations so are lending booms dangerous in this paper we investigate empirically this question using a broad sample of lending boom episodes over 40 years with a special eye for latin america our results indicate that 1 lending booms are often associated with i a domestic investment boom ii an increase in domestic interest rates iii a worsening of the current account iv a declines in reserves v a real appreciation vi a decline in output growth 2 typical lending booms do not increase substantially the vulnerability of the banking sector or the balance of payments comparing latin america and the rest of the world we find that latin america lending booms make the economy considerably more volatile and vulnerable to financial and balance of payment crisis

securitized markets international capital flows and global welfare we study the effect of collateralized lending and securitization on the global supply of securitized assets welfare and international net and gross capital flows in a two country general equilibrium model with idiosyncratic investment risk the financial sectors in the two countries home and foreign differ by the collateral requirement for investment loans with home requiring lower margins in autarky home endogenously supplies more assets and enables more risk sharing upon financial integration capital flows from foreign to home leading to lower interest rates and an increase in the global supply of assets foreign enjoys substantial welfare gains through better risk sharing and portfolio reallocation while the welfare experience for home is ambiguous gross capital flows arise when agents face aggregate shocks to the expected payoff to investment projects but can collapse when shocks concern the variance of returns

balanced bayesian mechanisms in the transferable utility case a number of authors have identified conditions on beliefs that guarantee the existence of bayesian incentive compatible mechanisms with balanced transfers we present a new easy to interpret condition and we show that it is strictly more general than all the other conditions found in the literature we also study conditions guaranteeing the bayesian implementability of all social decision rules with balanced budget mechanisms

money liquidity and monetary policy in a market based financial system banking and capital market developments are inseparable and funding conditions are closely tied to fluctuations in the leverage of market based financial intermediaries offering a window on liquidity the balance sheet growth of broker dealers provides a sense of the availability of credit contractions of broker dealer balance sheets have tended to precede declines in real economic growth even before the current turmoil for this reason balance sheet quantities of market based financial intermediaries are important macroeconomic state variables for the conduct of monetary policy

do surges in international capital inflows influence the likelihood of banking crises this article asks whether capital inflows bonanzas increase the probability of banking crises and whether this occurs through a lending boom mechanism results indicate that bonanzas more than triple the odds of a crisis raising its probability to 14 from an unconditional probability of 4 this effect exists in the absence of a lending boom and is found in both net and gross inflows bonanzas this effect is driven by portfolio equity and debt flows while the effect of debt is channelled through excessive lending the effect of portfolio equity flows is present even in the absence of a lending boom

early birds late risers and sleeping beauties bank credit growth to the private sector in central and eastern europe and in the balkans abstract following a period of privatization and restructuring commercial banks in central and eastern europe and more recently in the balkans have expanded rapidly their lending to the private sector this paper studies whether these developments are consistent with a process of convergence and structural financial deepening by estimating an equilibrium level of the bank credit to gdp ratio it concluded that while there is no clear evidence that the recent increases in bank credit ratios is inconsistent with financial deepening policy makers will have to evaluate carefully its implications for macroeconomic developments and financial stability

equilibrium credit the reference point for macroprudential supervisors equilibrium credit is an important concept because it helps identify excessive credit provision this paper proposes a two stage approach to determine equilibrium credit it uses two stages to study changes in the demand for credit due to varying levels of economic financial and institutional development of a country using a panel of high and middle income countries over the period 1980 2010 this paper provides empirical evidence that the credit to gdp ratio is inappropriate to measure equilibrium credit the reason for this is that such an approach ignores heterogeneity in the parameters that determine equilibrium credit across countries due to different stages of economic development the main drivers of this heterogeneity are financial depth access to financial services use of capital markets efficiency and funding of domestic banks central bank independence the degree of supervisory integration and experience of a financial crisis countries in europe and central asia show a slower adjustment of credit to its long run equilibrium compared with other regions of the world

public good provision with constitutional constraint this article studies the public good provision problem in which the principal faces a constitutional constraint in the sense that in order for a public good provision mechanism to be implemented it must first be approved by agents under a prespecified voting rule i find that as long as the voting rule is not the unanimity rule the principal can propose a mechanism such that first best efficiency of provision of the public good is achieved i also consider various constraints such as prohibition of discriminatory mechanisms and the existence of vote buying and discuss optimal voting rules in these situations

incentive compatibility and individual rationality in public good economies abstract hurwicz s theorem states that pareto optimality individual rationality and incentive compatibility are inconsistent in a class of private goods economies a similar result is obtained by ledyard and roberts in a class of public good economies hurwicz and walker show that generically there are no incentive compatible and pareto optimal mechanisms in a class of both private and public goods economies without imposing pareto optimality this paper explores the possiblity of the existence of incentive compatible and autarkically individually rational mechanisms in a class of public good economies autarkic individual rationality which strengthens individual rationality in a natural way and incentive compatibility are shown to be inconsistent

financial development financial fragility and growth the authors study the apparent contradiction between two strands of the literature on the effects of financial intermediation on economic activity on the one hand the empirical growth literature finds a positive effect of financial depth as measured by for instance private domestic credit and liquid liabilities for example levine loayza and beck 2000 on the other hand the banking and currency crisis literature finds that monetary aggregates such as domestic credit are among the best predictors of crises and their related economic downturns for example kaminski and reinhart 1999 the authors account for these contrasting effects based on the distinction between the short and long run impacts of financial intermediation working with a panel of cross country and time series observations they estimate an encompassing model of short and long run effects using the pooled mean group estimator developed by pesaran shin and smith 1999 their conclusion from this analysis is that a positive long run relationship between financial intermediation and output growth coexists with a mostly negative short run relationship the authors further develop an explanation for these contrasting effects by relating them to recent theoretical models by linking the estimated short run effects to measures of financial fragility namely banking crises and financial volatility and by jointly analyzing the effects of financial depth and fragility in classic panel growth regressions

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

leverage cycles and the anxious economy ing opportunities for emerging economies their access to international markets has turned out to be very volatile with frequent periods of market closures even worse as we will show emerging economies with sound fundamentals are the ones that issue less debt during these closures the goal of this paper is to present a theory of asset pricing that will shed light on the problems of emerging assets like emerging markets that are not yet mature enough to be attractive to the general public their marginal buyers are liquidity constrained investors with small wealth relative to the whole economy who are also marginal buyers of other risky assets we will use our theory to argue that the periodic problems faced by emerging asset classes are sometimes symptoms of what we call a global anxious economy rather than of their own fundamental weaknesses

the scope of anonymous voluntary bargaining under asymmetric information we present a model of anonymous collective bargaining where individuals preferences and information may be significantly interdependent we show that the bargaining outcome becomes independent of individuals preferences and information as the bargaining group increases in size as a corollary we show that anonymous voluntary bargaining completely fails in large groups either the difference between the bargaining outcome and the status quo vanishes as the size of the group becomes larger or the bargaining becomes coercive and results in a violation of at least some individuals rights the result provides a rationale for the inherent difficulty of reform in the presence of asymmetric information

evidence of bank market discipline in subordinated debenture yields 1983 1991 we examine debenture yields over the period 1983 1991 to evaluate the market s sensitivity to bank specific risks and conclude that investors have rationally reflected changes in the government s policy toward absorbing private losses in the event of a bank failure although this evidence does not establish that market discipline can effectively control banking firms it soundly rejects the hypothesis that investors cannot rationally differentiate among the risks undertaken by the major u s banking firms an increasingly important issue in the regulation of financial institutions concerns the extent to which market investors can will recognize and control the risks of banking firms although the banking act of 1933 replaced some private risk bearing with federal deposit insurance legislators were reluctant to displace market discipline very extensively flood 1992 by the early 1980s however u s regulators had come to protect virtually all bank liability holders from credit losses most visibly at large banks which were deemed too big to fail sprague 1986 o hara and shaw 1990 this extension of the government safety net largely reflects a skepticism on the part of regulators that normal market forces could adequately identify and control bank risks while u s regulators have recently shown an increased willingness to let some bank investors bear default losses an official suspicion of the efficacy of market discipline remains widespread by contrast some prominent academic economists argue that market investors in bank debentures could provide timely and effective control over banking firms risk exposures and that the social cost of supervising banks would be lower if regulators ceded greater

financial crises and balance of payments crises a simple model of the southern cone experience abstract this paper starts from a simple model of the domestic banking sector and develops the potentially destabilizing macroeconomic consequences of its role in intermediating foreign capital inflows both financial and balance of payments crises may result reminiscent of the southern cone experience

specification tests of the money demand function in an open economy this paper addresses empirically the issues of selecting the appropriate opportunity cost and scale variables of the money demand function in the presence of alternative nonnested hypotheses as part of the process of model specification the role of currency substitution in the demand for money function in an open economy is examined the tests are carried out with quarterly data from the open economy of greece over the floating exchange rate period 1975 82

credit market competition and capital regulation market discipline for financial institutions can be imposed not only from the liability side as has often been stressed in the literature on the use of subordinated debt but also from the asset side this will be particularly true if good lending opportunities are in short supply so that banks have to compete for projects in such a setting borrowers may demand that banks commit to monitoring by requiring that they use some of their own capital in lending thus creating an asset market based incentive for banks to hold capital borrowers can also provide banks with incentives to monitor by allowing them to reap some of the benefits from the loans which accrue only if the loans are in fact paid off since borrowers do not fully internalize the cost of raising capital to the banks the level of capital demanded by market participants may be above the one chosen by a regulator even when capital is a relatively costly source of funds this implies that capital requirements may not be binding as recent evidence seems to indicate

credit provision and banking stability after the great financial crisis the role of bank regulation and the quality of governance abstract in response to the great financial crisis gfc bank regulatory regimes were tightened world wide to strengthen banking stability and the resilience of the banking sectors yet it is often claimed that regulatory tightening may lead banks to cut back on lending and comes at the cost of a lower loan supply the present paper uses a country panel for 50 advanced and emerging market economies to analyze how the post crisis tightening in supervision and regulation affected aggregate bank stability and aggregate credit growth we find that higher capital buffers improved aggregate bank stability after the gfc whereas a strengthening of supervisory independence helped to reduce the decline in domestic credit and improved the stability of banks both effects have been stronger for countries with relatively poor institutions thus our results suggest that bank supervision regulation and institutions tend to be substitutes rather than complements

good bye financial repression hello financial crash some unintended consequences of financial liberalization in latin america are analyzed in this paper intrinsic imperfectious in financial markets and the policy dilemmas they pose are reviewed first the stylized facts of southern cone experiments in financial liberization are then presented alternative ways of organlzing domestic capital markets under latin american conditions are discussed and an eclectic reform mongering program is proposed

uma avaliacao dos impactos do salario minimo sobre o nivel de pobreza metropolitana no brasil this paper estimates the impact of recent minimum wage adjustments on poverty level for the six major brazilian metropolitan areas we make a decomposition of the observed variation on poverty level registered for a sample of longitudinal data based on a monthly employment survey pme ibge according to the decomposition we point the share of the observed variation on poverty level due to the wage and ocupational status variation of workers affected by the minimum legislation we break the decomposition in several steps to be able to consider several alternatives of the group of workers affected by the minimum wage legislation we have evidences of significant impacts of minimum wage on poverty level for metropolitan areas the medium elasticity for the period analyzed 1995 1998 was approximately 0 4 when this effect is incorporated which means that in the very short run poverty rises in brazilian metropolitan areas when the value of the minimum wage is increased

leverage across firms banks and countries we present new stylized facts on bank and rm leverage during the period 2000 2009 using internationally comparable micro level data from many countries we document the following patterns a there was an increase in leverage for investment banks prior to the sub prime crisis b there was no visible increase in leverage for the typical commercial bank and non nancial rm c o balance sheet items constitute a big fraction of assets especially for large commercial banks in the us whereas investment banks do not report these items d the leverage ratio is procyclical for investment banks and for large commercial banks in the us e banks in emerging markets with tighter bank regulation and stronger investor protection experienced signicantly less deleveraging during the crisis the results suggest that excessive risk taking before the crisis was not easily detectable because the risk involved the quality rather than the quantity of assets

a new database on the structure and development of the financial sector this article introduces a new database of indicators of financial structure and financial development across countries and over time the database is unique in that it combines a wide variety of indicators that measure the size activity and efficiency of financial intermediaries and markets it improves on previous efforts by presenting data on the public share of commercial banks introducing indicators of the size and activity of nonbank financial institutions and constructing measures of the size of bond and primary equity markets this article introduces a new database the first to provide comprehensive measures of the development structure and performance of the financial sector this database is the first to define and construct indicators of the size and activity of nonbank financial intermediaries such as insurance companies pension funds and non deposit money banks it is also the first to include indicators of the size of primary equity markets and primary and secondary bond markets in constructing the database authors carefully deflate measures and match stock and flow variables

correlated information and mechanism design in models of asymmetric information possession of private information leads to rents for the possessors this induces mechanism designers to distort away from efficiency the authors show that this is an artifact of the presumption that information is independently distributed rent extraction in a large class of mechanism design games is analyzed and a necessary and sufficient condition for arbitrarily small rents to private information is provided additionally the two person bargaining game is shown to have an efficient solution under first order stochastic dominance and a hazard rate condition similar conditions allow full rent extraction in milgrom weber auctions

us monetary policy and the global financial cycle us monetary policy shocks induce comovements in the international financial variables that characterize the global financial cycle a single global factor that explains an important share of the variation of risky asset prices around the world decreases significantly after a us monetary tightening monetary contractions in the us lead to significant deleveraging of global financial intermediaries a decline in the provision of domestic credit globally strong retrenchments of international credit flows and tightening of foreign financial conditions countries with floating exchange rate regimes are subject to similar financial spillovers

correlated information mechanism design and informational rents abstract cremer and mclean econometrica 56 1988 1247 1258 obtain a sufficient and necessary condition for full surplus extraction in bayesian nash equilibrium the rank condition which mcafee and reny econometrica 60 2 1992 395 421 later generalize for continuous type spaces this paper shows that if the principal does not know how noisy is the agent s signal or equivalently when signals available to an agent can be ranked by blackwell s informativeness and an agent s informativeness is independent of others information the rank condition fails to hold conversely when rank condition fails and informational rents are left to an agent the model can be interpreted as if the principal were uncertain about the informativeness of the agent s signal

overcoming incentive constraints by linking decisions consider a bayesian collective decision problem in which the preferences of agents are private information we provide a general demonstration that the utility costs associated with incentive constraints become negligible when the decision problem is linked with a large number of independent copies of itself this is established by defining a mechanism in which agents must budget their representations of preferences so that the frequency of preferences across problems mirrors the underlying distribution of preferences and then arguing that agents incentives are to satisfy their budget by being as truthful as possible we also show that all equilibria of the linking mechanisms converge to the target utility levels the mechanisms do not require transferable utility or interpersonal comparisons of utility and are immune to manipulations by coalitions

the role of economic theory in modelling the long run this argues for a closer link between the modelling of the long run relations in applied economics and the intertemporal equilibrium notion from economic theory this abstract was borrowed from another version of this item

ride the wild surf an investigation of the drivers of surges in capital inflows over the past 15 years gross inflows to industrial and developing countries have enjoyed a wild ride after reaching record highs in the run up to the global financial crisis they collapsed dramatically in 2008 09 as signs of global recovery reappeared capital inflows resumed although at different speeds the recovery in flows was faster and sharper in developing countries this paper aims at understanding the domestic and external drivers of these surges in gross inflows using quarterly data for 67 countries from 1975 to 2010 it finds that domestic and external factors have significant explanatory power in driving surges of inflows this finding holds for the sample of industrial countries whereas domestic factors play a significantly larger role in explaining surges to developing countries zooming into the findings shows that a financial booms tend to attract massive capital inflows b surges to either industrial or developing countries are driven by regional contagion and c strong growth and natural resource abundance are keys to attract inflows of foreign capital into developing countries

capital inflow surges in emerging economies how worried should latin america and the caribbean be in the years leading up to the global economic crisis latin america and the caribbean received large capital inflows nonetheless the region survived the albeit short lived dramatic events of 2007 09 reasonably well with no financial crisis in any of the larger economies after the crisis capital inflows rose again in 2010 gross inflows to seven latin american countries argentina brazil chile colombia mexico peru and venezuela amounted to more than 6 percent of gross domestic product gdp and net inflows exceeded 3 percent of gdp more recently following the may 2013 speech of then chairman of the u s federal reserve ben bernanke there has been concern regarding the potential effects of tapering asset purchases by the u s federal reserve system and rising interest rates possibly spelling the end of large capital inflows to the latin american and caribbean region the literature on capital inflows suggests that while these flows represent an opportunity to spur investment and growth they may also increase vulnerability to financial crises macroeconomic instability and ultimately recession a relevant question then is whether the region can declare victory in being able to manage large capital inflows successfully or whether risks remain that justify strong measures our starting point is that the region has enjoyed strong surges in capital inflows we therefore decided to condition the analysis on surges occurring we do not seek to explain the reasons for such a surge one justification for this decision is that capital flows appear to be driven as much if not more by push rather than pull factors more specifically we seek to understand what determines whether such surges end in either a banking crisis or a recession while there is a substantial literature on the determinants of capital inflows their potential impacts have received much less attention the contribution of this paper is to analyze when inflow surges may end in severe economic problems including financial or macroeconomic instability rather than to identify the determinants of those surges we must first tackle the question of how to define a capital inflow surge we are helped in this regard by a small but growing literature however the current definitions of inflow surges in the literature may be injudicious we propose a new definition which considers the total size of the inflow episode across countries we also employ a more traditional definition based on yearby year inflows relative to a country specific threshold we contrast relevant statistics on the identified episodes using these two definitions and compare our episodes with others found in the literature we also consider whether the analysis should be conducted using gross or net inflows we take the view that employing net flows may discard useful information and that gross flows are relevant where financial instability is a potential concern even if net flows are zero a domestic financial system may intermediate large gross inflows when domestic residents purchase assets abroad we choose to focus on gross inflows but we include gross outflows as a potential explanatory variable so as not to lose information 1the empirical analysis in this paper develops a set of parsimonious models that discriminate reasonably well between the different economic outcomes we then analyze the case of a typical country from the region with a recent capital inflow surge providing a set of simulations to illustrate the economic magnitude of our results we simulate the changes in the estimated probabilities of negative outcomes given changes in certain critical variables we suggest that depending on the country inflow characteristics different policy measures may then be justified however a caveat is that emerging economies in general and latin america and the caribbean in particular have been experimenting with new policy measures and we are not able to evaluate their potential effectiveness in this paper

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

are windfalls a curse abstract a puzzling feature of temporary terms of trade booms is that some countries have responded to such windfalls by running current account deficits furthermore those countries that ran current account deficits failed to attain greater post boom growth rates indicating the deficits were consumed or invested in low quality projects the point we make is that the structure of the fiscal process is critical in determining outcomes if fiscal control is unitary then the consumption smoothing effect is operative and representative agent models of the current account have predictive power however if control is divided among several fiscal claimants a voracity effect appears which counteracts the consumption smoothing effect leading to a deterioration of the current account in response to a positive temporary shock we model the interaction among fiscal claimants as a dynamic game and show that in equilibrium aggregate appropriation increases more than the windfall itself this results in a deterioration of the current account we also show that all the windfall is dissipated with the country experiencing no increase in welfare 1998 elsevier science b v

currency crises are they all the same abstract the plethora of currency crises around the world has fueled many theories on the causes of speculative attacks the first generation models focus on fiscal problems while the second generation models emphasize countercyclical policies and self fulfilling crises in the 1990s models pinpoint to financial excesses with the crisis of argentina in 2001 models of sovereign default have become popular again while the theoretical literature has emphasized variety the empirical literature has supported the one size fits all models this paper contributes to the empirical literature by assessing whether the crises of the last 30 years are of different varieties

the terms of trade the real exchange rate and economic fluctuations this paper examines the relationship between terms of trade and business cycles using a three sector intertemporal equilibrium model and a large multicountry database results show that terms of trade shocks account for nearly one half of actual gdp variability the model explains weak correlations between net exports and terms of trade the harberger laursen and metzler effect and produces large and weakly correlated deviations from purchasing power parity and real interest rate parity terms of trade shocks cause real appreciations and positive interest differentials although productivity shocks have opposite effects the puzzle that welfare gains of international asset trading are negligible is left unresolved copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the effect of bank bail outs in the eu abstract the financial crisis renewed the debate on the bail out of financial institutions questioning the effectiveness of such an intervention in restoring normal economic conditions this paper analyzes the effect on the real economy of state financial support to distressed banks using a panel approach that covers all countries in the eu throughout the financial crisis results show that state financial support was able to enhance economic conditions by restoring trust in financial markets state support boosted the ongoing substitution between securities and bank lending as the main financing channel of non financial firms

the paradox of liquidity the more liquid a firm s assets the greater their value in a short notice liquidation it is generally thought that a firm should find it easier to raise external finance against more liquid assets this paper focuses on the dark side of liquidity greater asset liquidity reduces the firm s ability to commit to a specific course of action as a result greater asset liquidity can in some circumstances reduce the firm s capacity to raise external finance firms with excessively liquid assets are in the best position to finance illiquid projects this leads us to a theory of financial intermediation and disintermediation based on the liquidity of assets

asymmetric information bargaining problems with many agents a yes or no decision must be made about some issue all agents must agree the coase theorem asserts that the efficient outcome will always result suppose the value positive or negative that an individual attaches to an affirmative decision is privately known to that individual it is proved under very mild conditions that with independent types as the number of agents increases the probability of an affirmative efficient decision goes to zero an example in which it is common knowledge that an affirmative decision is efficient and yet the probability of such a decision goes to zero is given

the collapse of the mexican peso what have we learned the collapse of the mexican peso what have we learned in the first quarter of 1995 mexico found itself in the grip of an intense financial panic foreign investors fled the country despite very high interest rates an undervalued currency and financial indicators that pointed to long term solvency the fundamental conditions of the mexican economy cannot account for the extent of the crisis the crisis was not the result of irresponsible fiscal behaviour the crisis was due to unexpected shocks that occurred in 1994 the inadequate policy response to those shocks the increased vulnerability to panic and finally panic itself in the aftermath of the march assassination the exchange rate experienced a nominal devaluation of around 10 and interest rates increased by 7 percentage points however capital outflows continued the policy response was to maintain the exchange rate rule and to prevent further increases in interest rates interest rates were held down by expanding domestic credit and by converting short term peso denominated government liabilities cetes falling due into dollar denominated bonds tesobonos a fall in international reserves and an increase in short term dollar denominated debt resulted the government simply ended up illiquid and therefore financially vulnerable illiquidity exposed mexico to a self fulfilling panic jeffrey sachs aaron tornell and andres velasco

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

public goods participation constraints and democracy a possibility theorem abstract it is well known that ex post efficient mechanisms for the provision of indivisible public goods are not interim individually rational however the corresponding literature assumes that agents who veto a mechanism can enforce a situation in which the public good is never provided this paper instead considers majority voting with uniform cost sharing as the relevant status quo efficient mechanisms may then exist which also satisfy all agents interim participation constraints in this case ex post inefficient voting mechanisms can be replaced by efficient ones without reducing any individual s expected utility intuitively agents with a low willingness to pay have to contribute more under majority rule than under an efficient mechanism with a balanced budget although this possibility theorem is not universal in the sense of schweizer 2006 an asymptotic possibility is obtained for certain type distributions

a small sample study of the new keynesian macro model this paper presents a small sample study of the three equation three variable new keynesian macro model while the point estimates imply that the fed has been stabilizing inflation fluctuations since 1980 our econometric analysis suggests considerable uncertainty regarding the stance of the fed against inflation the canonical new keynesian macro model is strongly rejected by the likelihood ratio test but we propose the direction in which it needs to be modified in order to fit the data

risk taking spillovers of u s monetary policy in the global market for u s dollar corporate loans abstract we study the effects of u s interest rates and other factors on risk taking in the global market for u s dollar syndicated term loans we find that before the global financial crisis both u s and non u s lenders originated ex ante riskier loans to non u s borrowers in response to a decline in short term u s interest rates and after the crisis in response to a decline in longer term u s interest rates after the crisis this behavior was more prominent for shadow banks and less prominent for banks with relatively low capital separately before the crisis lenders originated less risky loans in response to u s dollar appreciation across the periods the responses to risk appetite and economic uncertainty varied to the extent that the federal reserve affects u s interest rates we provide evidence of global risk taking spillovers of u s monetary policy which are important but not dominant factors for risk taking in the market

public good provision with many participants for a nonexcludable public good with benefit and cost functions independent of the number of participants this paper studies second best allocations under bayesian interim incentive compatibility and interim individual rationality as the number of participants becomes large second best provision levels converge in distribution to first best levels if the latter are bounded second best provision levels become large in absolute terms but small relative to first best levels if benefit and cost functions are isoelastic in contrast for an excludable public good the ratio of second best to first best levels is bounded away from zero

credit booms and macrofinancial stability this paper explores several questions about credit booms and busts when do credit booms occur when do they end up in busts and when do they not what are the implications for different policies if curbing credit growth and or mitigating the associated risks is an objective we find that credit booms are often associated with financial reform and economic growth they also tend to be more frequent in fixed exchange rate regimes only one in three credit boom episodes are followed by a financial crisis these booms tend to be larger and last longer macroprudential tools have at times proven effective in containing booms and more often in limiting the consequences of busts due to the buffers they helped to build

from ngos to banks does institutional transformation alter the business model of microfinance institutions microfinance which pledges to provide financial services to people without access to banking is chiefly run by non governmental organizations ngos little is known about the extent to which the transformation of these ngos into shareholder owned and most often regulated firms affects the way microfinance institutions mfis conduct their business by applying the event study methodology to 66 mfis that have transformed we quantify the effect that transformation has on the mfis business models our results suggest that portfolio yield is driven down by 3 9 percentage points due to transformation indicating that clients get more favorable interest rates at the same time mfis are able to significantly cut down their operational expenses of which 1 1 percentage points can be attributed to transformation other findings include a steep increase in commercial debt leverage and deposits a significant decrease in the fluctuation of funding costs and a sharp rise in average loan size profitability goes down in the short and medium term while return on equity is driven up in the medium to long run by exploiting within mfi data our approach goes beyond previous studies that mainly relied on between mfi data overall the results suggest that transformed mfis become an attractive environment for investors potentially encouraging a more profit seeking behavior among transformed mfis

financial fragility in the great moderation abstract a nascent literature explores the measurement of financial fragility this paper considers evidence for rising financial fragility during the 1984 2007 great moderation in the u s the literature suggests that macroeconomic stability combined with strong growth of credit to asset markets in asset prices and in credit relative to output are all indicators of rising financial fragility we show each of these trends in the great moderation we derive the testable implication that in the great moderation credit growth is driven more by past credit growth and less by output growth allen and gale 2000 relative to pre great moderation years results from a var model estimated on quarterly data for 1955 2007 are consistent with the hypothesis this invites a reinterpretation of the great moderation our methodology may help understand when a credit boom turns into a credit bubble and contributes to the development of methods of measuring financial fragility
