spillovers through banking centers a panel data analysis of bank flows abstract this paper presents evidence that spillovers through bank lending contributed to the transmission of currency crises during the recent episodes of financial instability in emerging markets the innovation of the paper is that it looks beyond aggregated measures of contagion into the structure of bank flows disaggregating by banking centers the main findings are that spillovers caused by banks exposures to a crisis country help predict flows in third countries after the mexican and asian crises but not after the russian crisis in the latter there is evidence of a generalized outflow from emerging markets the importance of spillovers through banking centers suggests that countries might reduce contagion risk by diversifying the sources of their financing and by carefully monitoring borrowing from creditors exposed to potential crisis countries

fiscal expansions unemployment and labor force participation theory and evidence structural vars indicate that for many oecd countries labor force participation employment and the unemployment rate significantly increase following increases in government expenditures under a variety of specifications and identification schemes fiscal expansions also tend to increase real wages existing models have difficulties in generating such responses we show that the empirical regularities can be reproduced with two additions into a standard new keynesian model with matching frictions a a labor force participation choice and b workers heterogeneity

on the importance of the participation margin for labor market fluctuations abstract conventional analyses of labor market fluctuations ascribe a minor role to labor force participation we show by contrast that flows based analyses imply that the participation margin accounts for around one third of unemployment fluctuations a novel stock flow apparatus establishes these facts delivering three further contributions first the role of the participation margin appears robust to adjustments for spurious transitions induced by reporting error second conventional stocks based analyses are subject to a stock flow fallacy neglecting offsetting forces of worker flows on the participation rate third increases in labor force attachment among the unemployed during recessions are a leading explanation for the role of the participation margin

effect of credit guarantee policy on survival and performance of smes in republic of korea this study evaluates the effect of credit guarantee on smes at the firm level to estimate the effect of credit guarantee we analyze relations between credit guarantee the survival of guaranteed firms and their productive performance the result indicates that credit guarantee frequency enabled guaranteed firms to achieve good performances in general on the contrary the effect of guarantee amounts is ambiguous in that there is difference between the contemporary effect and the lagged effect therefore we conclude that credit guarantee satisfied partially its goal to alleviate smes difficulty in acquiring finance and to stabilize employment

notes for a new guide to keynes i wages aggregate demand and employment i revisit the general theory s discussion of the role of wages in employment determination through the lens of the new keynesian model the analysis points to the key role played by the monetary policy rule in shaping the link between wages and employment and in determining the welfare impact of enhanced wage exibility i show that the latter is not always welfare improving

the cyclicality of the user cost of labor abstract the user cost of labor is the expected difference between the present discounted value of wages paid to a worker hired in the current period and that paid to a worker hired in the next period analogous to the price of any long term asset the user cost not wage is the relevant price for a firm that is considering adding a worker i construct its counterpart in the data and estimate that it is substantially more procyclical than average wages or wages of newly hired workers i demonstrate an application of the finding using the textbook search and matching model

measuring sovereign risk spillovers and assessing the role of transmission channels a spatial econometrics approach abstract we contribute to the literature on international risk spillovers by developing a unified framework based on spatial econometrics that enables us to address the following questions i what are the effective transmission channels real linkages and informational channels of international risk spillovers across countries and or regions ii what are the most dominant ones and iii which countries are most at risk for their environment and which are suffering the most from international exposure our analysis based on 41 advanced and emerging economies from 2008q1 to 2012q4 shows that among the considered channels for explaining international spillovers of sovereign bond spreads the informational channel is of utmost importance our results challenge previous findings from the literature in which the empirical strategy did not accommodate altogether important features of country spillovers such as the co existence of multiple transmission channels in the presence of contemporaneous and time lagged interactions ultimately our stress testing analysis reveals important insights on countries prone either to international spillovers international exposure or both at the regional and the worldwide level

identification of financial factors in economic fluctuations we estimate demand supply monetary investment and nancial shocks in a var identified with a minimum set of sign restrictions on us data we find that financial shocks are major drivers of fluctuations in output stock prices and investment but have a limited effect on inflation in a second step we disentangle shocks originating in the housing sector shocks originating in credit markets and uncertainty shocks in the extended set upfinancial shocks are even more important and a leading role is played by housing shocks that have large and persistent effects on output

dynamics of worker flows and vacancies evidence from the sign restriction approach this paper establishes robust dynamic features of the worker reallocation process in the us labor market i use structural vars with sign restrictions which take the form of restricting the short run negative relationship between vacancies and unemployment i e beveridge curve despite the weakness of these restrictions they reveal a clear unambiguous pattern that when unemployment increases and vacancies drop i both the separation rate and gross separations rise quickly and remain persistently high ii the job finding rate and vacancies drop in a hump shaped manner and iii gross hires respond little initially but eventually rise these results point to the importance of job loss in understanding us labor market dynamics this pattern also holds with respect to different kinds of shocks that induce the same beveridge curve relationship this paper also considers the disaggregate model which uses data disaggregated into six demographic groups and incorporates transitions into and out of the labor force i show that the separation rate continues to play a dominant role among prime age male workers while for other groups changes in the job finding rate are more important copyright 2009 john wiley sons ltd

business cycle measurement with some theory a method to evaluate cyclical models not requiring knowledge of the dgp and the exact specification of the aggregate decision rules is proposed we derive robust restrictions in a class of models use some to identify structural shocks in the data and others to evaluate the class or contrast sub models the approach has good properties even in small samples and when the class of models is misspecified the method is used to sort out the relevance of a certain friction the presence of rule of thumb consumers in a standard class of models

unemployment dynamics across oecd countries abstract the european community and the us have experienced vastly different unemployment dynamics over the last two decades this paper investigates whether these differences are due to exposure to different shocks or reacting differently to the same shocks with the premise of a search theoretic framework and a structural var methodology the paper robustly identifies aggregate versus reallocative shocks with the exception of spain where most of the dynamics seem to be driven by reallocation it is found that most differences in unemployment dynamics arise because of differences in responses to shocks in particular the us labour market is quicker to adjust than the european community this implies that eec economies might be dynamically sclerotic even if the size of the steady state labour market flows give the impression that european labour markets are quite active various identifying assumptions additional labour supply shocks and different variables are used yet the results appear robust

how bad are twins output costs of currency and banking crises we investigate the output effects of banking and currency crises in emerging markets focusing on whether twin crises entail especially large losses recent literature emphasizes the costs of financial crises and suggests that twin crises are particularly damaging to the real economy using a panel data set for 1975 97 we find that currency banking crises are very costly reducing output by about 5 8 8 10 over a 2 4 year period the cumulative loss of both types of crises is therefore very large we do not find however additional feedbacks or interactive effects associated with twin crises further damaging the economy

detecting contagion in a multivariate time series system an application to sovereign bond markets in europe this paper proposes an original three part sequential testing procedure stp with which to test for contagion using a multivariate model first conditional on breaks in the conditional mean the procedure identifies distinct structural breaks in the volatility of a given set of countries a further structural break test applied to the correlation matrix identifies and then dates the potential contagion mechanisms as a third element the stp tests for the distinctiveness of the break dates previously found as a result of using multi dimensional data the stp has high testing power and is able to locate the dates of contagion more precisely the application to european long term interest rates shows that immediate contagion from greece does not take place but the dynamic spillovers are shown to increase after controlling for breaks in the different model parameters for other countries we find evidence of both contagion and flight to quality mechanisms

the effects of fiscal shocks on employment and the real wage we study the transmission of fiscal shocks in the labor market we employ a structural var and base identification on the restrictions that shocks to government consumption investment and employment must raise output and deficits these restrictions hold in both prototype real business cycle rbc and new keynesian models shocks to government consumption and investment increase real wages and employment contemporaneously both at state level and in the aggregate the dynamics in response to employment shocks are mixed increases in government employment raise the real wage and total employment in the aggregate however in one third of the states they reduce total employment

tax smoothing in frictional labor markets we re examine the optimality of tax smoothing from the point of view of frictional labor markets our central result is that whether or not this cornerstone optimal scal policy pre

building a composite help wanted index abstract this paper builds a measure of vacancy posting over 1951 2009 that captures the behavior of total print and online help wanted advertising and can be used for time series analysis of the us labor market

labor market participation unemployment and monetary policy models of unemployment and monetary policy usually assume constant participation incorporating a participation decision into a standard new keynesian model with matching frictions we show that market tightness becomes endogenously more volatile because both the opportunity cost of home production and the reservation wage vary with participation the model can simultaneously explain the low volatility of participation the high volatility of unemployment and a procyclical workers outside option of working a policy of strict inflation targeting is close to optimal and increasing the response of the interest rate to inflation does not have a large impact on the volatility of unemployment because of the endogenous response of participation

contagion and trade why are currency crises regional abstract currency crises tend to be regional they affect countries in geographic proximity this suggests that patterns of international trade are important in understanding how currency crises spread above and beyond any macroeconomic phenomena we provide empirical support for this hypothesis using data for five different currency crises in 1971 1973 1992 1994 and 1997 we show that currency crises affect clusters of countries tied together by international trade by way of contrast macroeconomic and financial influences are not closely associated with the cross country incidence of speculative attacks

what is happening to the impact of financial deepening on economic growth i introduction among the strongest elements of the modern economists canon is that financial sector development has a significant impact on economic growth a generation ago economists like goldsmith 1969 1 and mckinnon 1973 began to draw attention to the benefits of financial structure development and financial liberalization by the early 1990s mckinnon 1991 12 could write with confidence that now however there is widespread agreement that flows of saving and investment should be voluntary and significantly decentralized in an open capital market at close to equilibrium interest rates since the 1990s a burgeoning empirical literature has illustrated the importance of financial sector development for economic growth despite the growing consensus however we find that the link between finance and growth in cross country panel data has weakened considerably over time at the very time that financial sector liberalization spread around the world the influence of financial sector development on economic growth has diminished the seminal empirical work that established the growth finance link is king and levine 1993 which extended the cross country framework introduced in barro 1991 by adding financial variables such as the ratios of liquid liabilities or claims on the private sector to gross domestic product gdp to the standard growth regression they found a robust positive and statistically significant relationship between initial financial conditions and subsequent growth in real per capita incomes for a cross section of about 80 countries in the subsequent decade numerous empirical studies expanded upon this using both cross country and panel data sets for the post 1960 period 2 in this paper we reexamine the core cross country panel result and find that the impact of financial deepening on growth is not as strong with more recent data as it appeared in the original panel studies with data for the period from 1960 to 1989 we consider various explanations for this clear shift first we suggest that financial deepening has a positive effect on growth if not done to excess rapid and excessive deepening as manifested in a credit boom can be problematic even in the most developed markets because it can both weaken the banking system and bring inflationary pressures we test this hypothesis by looking at the finance growth nexus among countries that have or have not experienced financial sector crises we find that once crisis episodes are removed the finance growth relationship remains intact its weakening over time thus seems to be a result of an increased incidence of crises in later years our second and related hypothesis is that the widespread liberalization of financial markets that occurred in the late 1980s and early 1990s made financial deepening less effective this is reminiscent of robert lucas s 1975 critique of econometric policy evaluation advanced three decades ago policies that have promoted and or forced increases in financial depth over the past two decades may have altered the basic structural relationship between finance and growth this could occur if the observed benefits of financial deepening led many countries to liberalize before the associated legal and regulatory institutions were sufficiently well developed as a consequence the impact of financial deepening on growth would become smaller our evidence does not indicate that recent liberalizations are responsible for the breakdown of the finance growth link however there may be an indirect link as premature financial development can lead to financial crises that have real effects third we examine the role of global equity markets that have grown in importance and prominence in the years over which the finance growth relationship disappeared however we do not find any evidence to suggest that equity market growth has substituted for the role of credit markets and banks in particular

technology shocks and robust sign restrictions in a euro area svar we use a model based identification strategy to estimate the impact of technology shocks on hours worked and employment in the euro area the sign restrictions applied in the vector autoregression var analysis are consistent with a large class of dynamic stochastic general equilibrium dsge models and are robust to parameter uncertainty the results are in line with the conventional real business cycle rbc interpretation that hours worked rise as a result of a positive technology shock by comparing the sign restrictions method to the long run restriction approach of gali quaterly journal of economics 1992 709 38 we show that the results do not depend on the stochastic specification of the hours worked series or the data sample but only on the identification scheme

business cycles and labor market search the quantitative implications of labor market search for economic fluctuations are evaluated in the context of a real business cycle model incorporating labor market search into the model is found to improve its empirical performance along several dimensions in particular hours now fluctuate substantially more than wages and the contemporaneous correlation between hours and productivity falls in addition the model replicates the observation that output growth displays positive autocorrelation at short horizons overall the empirical results suggest that the labor market search environment embodies a quantitatively important propagation mechanism copyright 1996 by american economic association

labor supply factors and economic fluctuations we propose a new v ar identication scheme that enables us to disentangle labor supply shocks from wage bargaining shocks identication is achieved by imposing robust sign restrictions that are derived from a new keynesian model with endogenous labor force par ticipation according to our analysis on us data over the period 1985 2014 labor supply shocks and wage bargaining shocks are important drivers of output and unemployment both in the short run and in the long run these results suggest that identication strategies used in estimated new keynesian models to disentangle labor market shocks may be misguided we also analyze the behavior of the labor force participation rate through the lenses of our model wend that labor supply shocks are the main drivers of the participation rate and account for about half of its decline in the aftermath of the great recession

cross country causes and consequences of the crisis an update abstract we update rose and spiegel forthcoming rose and spiegel 2010 and search for simple quantitative models of macroeconomic and financial indicators of the great recession of 2008 09 we use a cross country approach and examine a number of potential causes that have been found to be successful indicators of crisis intensity by other scholars we check a number of different indicators of crisis intensity and a variety of different country samples while countries with higher income and looser credit market regulation seemed to suffer worse crises we find few clear reliable indicators in the pre crisis data of the incidence of the great recession countries with current account surpluses seemed better insulated from slowdowns

neutral technology shocks and the dynamics of labor input results from an agnostic identification this article studies the dynamic response of labor input to neutral technology shocks it uses benchmark dynamic stochastic general equilibrium models enriched with labor market search and matching frictions and investment specific technological progress that enables a new agnostic identification scheme based on sign restrictions on a structural vector autoregression svar the estimation supports an increase of labor input in response to neutral technology shocks this finding is robust across different perturbations of the svar model

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

fiscal and monetary policies and the cost of sudden stops abstract this article investigates the effects of monetary and fiscal policies on output growth during sudden stop balance of payments crisis in emerging markets and developing countries sudden stops in capital flows and subsequent deep recessions are a frequent occurrence in these countries but there is no professional consensus and little systematic empirical evidence shedding light on the macroeconomic policy mix most likely to limit output losses during these episodes to address this issue we investigate 83 sudden stop crisis in 66 countries using a baseline empirical model to control for the various determinants of output losses during sudden stops we measure the marginal effects of policy on output losses and find strong evidence that monetary tightening rise in the discount rate or unsterilized rise in international reserves and discretionary fiscal contraction are significantly correlated with larger output losses following a sudden stop fiscal expansion is associated with smaller output losses following a sudden stop but monetary expansion has no discernable effect the macroeconomic policy mix associated with the least output loss during a sudden stop financial crisis is a discretionary fiscal expansion combined with a neutral monetary policy

employment effects of product and labour market reforms are there synergies this article investigates the effect of product market liberalisation on employment allowing for interactions between policies and institutions in product and labour markets using panel data for oecd countries over the period 1980 2002 we present evidence that product market deregulation is more effective at the margin when labour market regulation is high the data also suggest that product market liberalisation may promote employment enhancing labour market reforms

revisiting the new normal hypothesis abstract the paper estimates the impact of crises on output growth augmenting cerra and saxena s 2008 analysis by extending the data until 2010 and by taking into account globalization and contagion effects the paper finds that the decline in output growth rates following currency banking and stock market crises are much larger in the sample ending in 2010 than in the one ending in 2001 the results are robust across different specifications and crisis databases the paper finds that globalization estimated using a factor augmented panel has benefitted economic growth in the long run but those gains have been diminishing in the new millennium moreover globalization also amplifies the negative effects of crises especially for upper middle and high income oecd countries starting with the new millenium as such lower output growth is to be expected as the new norm especially in these more advanced economies for a lot longer than what would have been expected in an usual cyclical recovery confirming el erian and pimco s 2009 statement of a new normal last but not least the estimation using a factor augmented panel leads to results consistent with thresholds effects of finance and growth and of globalization on growth
