Book excerpt: The dissertation comprises of three chapters. The first chapter studies the role of credit market frictions in transmitting time-varying aggregate uncertainty to economic activity. First, we document that changes in country-specific aggregate volatility are positively correlated with the current account dynamics but negatively correlated with investment, output and credit flows. Then we build an International Real Business Cycle model with credit market frictions that matches these empirical facts. The version of the model with no financial frictions can only account for positive correlation between volatility and current account, but implies counterfactual predictions for the other correlations. In the second chapter we analyze banking crises and lending of last resort (LOLR) in a quantitative model of financial frictions with bank defaults. We find that the LOLR, even if it induces an increase in banks' leverage, is beneficial for small open economies. We show that pools of small economies cannot be successful LOLRs for empirically reasonable levels of liquidity support: They need too many uncorrelated countries or large initial levels of reserves to be sustainable. A country with ample reserves like China can be a sustainable international LOLR. The third chapter analyzes supranational deposit insurance in a quantitative model of financial and sovereign debt crisis. We show that the common deposit insurance fund can bring about sizable economic benefits by weakening an adverse link between domestic banking sector stress and sovereign default risk. The model simulations suggest that the sustainability of such a fund requires a certain number of participating countries with strong fundamentals, while feasibility calls for risk-based insurance premiums. These results can inform the design of the common European deposit insurance fund.

Download or read book Essays on Market Frictions, Economic Shocks and Business Fluctuations written by Seungho Nah. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In the first essay, 'Financial Frictions, Intersectoral Adjustment Costs, and News-Driven Business Cycles', I show that an RBC model with financial frictions and intersectoral adjustment costs can generate sizable boom-bust cycles and plausible responses of stock prices in response to a news shock. Booms in the labor market, which make it possible for both consumption and investment to increase in response to positive news, are caused through two channels: the increases in value of marginal product of labor and the increases in value of collateral. Both of these channels enable firms to hire more workers. Intersectoral adjustment costs contribute to both channels by increasing the relative price of output and capital during expansions. Financial frictions enter in the forms of collateral constraints on firms, which influence the latter channel, and the financial accelerator mechanism driven by agency costs, which amplifies all the key variables. My model differs from previous studies in its ability to generate boom-bust cycles without restricting the functional form of consumption in household preferences and without requiring investment adjustment costs, variable capital utilization, or any nominal rigidities. In the second essay, 'Financial and Real Frictions as Sources of Business Fluctuations', I show that a negative shock to a financial or real friction in an economy can generate quantitatively significant and persistent recessions, even without a decrease in exogenous aggregate total factor productivity in a heterogeneous agents DSGE model. The increase in uncertainty that a firm is facing when it makes capital adjustment, however, is found to have a limited or dubious influence on economic activities. The roles of collateral constaints as a financial friction and nonconvex capital adjustment costs as a real friction in aggregate fluctuations are examined in this propagation mechanism. When these frictions become strengthened, the degree of capital misallocation is intensified, which leads to a drop of endogenous aggregate total factor productivity. As agents expect that the return to investment and endogenous TFP decrease, they reduce aggregate investment sharply, which also leads to a drop in employment. Interruption of efficient resource allocation coming from these two frictions is found out to be enough to generate a large and persistent aggregate flucutations even without introducing heterogeneity in firm-level productivity.

Book excerpt: The crisis of 2009 raised the question whether the financial conditions matter for the business cycles and the propagation of shocks originating in the financial sphere. I tried to drive a fine analysis of this issue using micro-founded general equilibrium models. The modelling choice was backed by empirical motivations. In three essays, i study the impact of monetary and financial shocks on growth and labour market dynamics. First, an expansionary monetary policy eases credit conditions, raises risk tolerance and the quality of borrowers and generates a liquidity effect. The potency of the monetary policy and the size of the credit channel depend considerably on the degree of financial frictions in the credit market. Second, a restrictive monetary policy shock, an positive credit shock and a positive uncertainty shocks have similar effects on the economy: they plunge the economy in a recession, with output, job creations, and hours worked decreasing, while unemployment and job destructions increase. In all cases the interest rate spread increase, therefore indicating that financial conditions deteriorate, which is interpreted as a sign that financial frictions play a critical role in the propagation of these shocks. Third, the interaction between financial and labour market frictions does exist. The interplay between the two indeed plays a role in propagating the shocks. A shock to net worth, a credit shock and an uncertainty shock play a non-trivial role for the dynamics on the labour market.

Book Synopsis Essays on Financial Frictions and Business Cycles by : Yankun Wang

Download or read book Essays on Financial Frictions and Business Cycles written by Yankun Wang. This book was released on 2011. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation I explore the relationship between the frictions in a country's financial market and its business cycle movements. It is well known that the financial market is far from perfect, and shocks originating in such market could have sizable impact on the real economy. On the other hand, evolvement in the financial market could also be a reflection of the real economy. For example, economic downturn often leads to high borrowing cost for a country in the international financial market. The essays in this dissertation present an analysis of this two-way relationship, both qualitatively and quantitatively. The first essay studies the link between country credit spreads - defined as the difference between a home country's cost of borrowing from the international credit market and the world riskless interest rate - and the domestic business cycle fluctuations. By combining both empirical and theoretical analysis, this essay shows that deteriorating credit markets are both reflections of a declining economy and a major factor that depresses economic activity. This study uses a quarterly dataset over the period 1972Q1 to 2010Q1 for South Korea. The second essay probes the importance of financial shocks in creating business cycles in the United States. It starts from a theoretical dynamic stochastic generating equilibrium model, which identifies positive financial shocks as those that drag down the corporate net worth while raising domestic output. An empirical analysis later uses this property to identify financial shocks and study their importance in creating business cycle movement for the U.S. in the past fifty years. This property is in stark contrast to technological shocks, which raise both corporate net worth and total output.
