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.

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.

This dissertation investigates the role of financial frictions stemming from asymmetric information in financial markets on the transmission of shocks, and the fluctuations in economic activity. Chapter 1 uses the targeted factor modeling to assess the contribution of national and international data to the task of forecasting provincial GDPs in Canada. Results indicate using national and especially US-based series can significantly improve the forecasting ability of targeted factor models. This effect is present and significant at shorter-term horizons but fades away for longerterm horizons. These results suggest that shocks originating at the national and international levels are transmitted to Canadian regions and thus reflected in the regional time series fairly rapidly. While Chapter 1 uses a non-structural, econometric model to tackle the issue of transmission of international shocks, the last two Chapters develop structural models, Dynamic Stochastic General Equilibrium (DSGE) models to assess spillover effects of the transmission of national and international shocks. Chapter 2 presents an international DSGE framework with credit market frictions to assess issues regarding the propagation of national and international shocks. The theoretical framework includes the financial accelerator, the bank capital and exchange rate channels. Results suggest that the exchange rate channel, which has long been ignored, plays an important role in the propagation of shocks. Furthermore, with these three channels present, domestic and foreign shocks have an important quantitative role in explaining domestic aggregates. In addition, results suggest that economies whose banks remain well-capitalized when affected by adverse shock experience less severe downturns. These results highlight the importance of bank capital in an international framework and can be used to inform the worldwide debate over banking regulation. In Chapter 3, I develop a two-country DSGE model in which banks grant loans to domestic as well as to foreign firms to study effects of these cross-border banking activities in the transmission of national and international shocks. Results suggests that cross-border banking activities amplify the transmission of productivity and monetary policy shocks. However, the impact on consumption is limited, because of the cross-border saving possibility between the countries. Moreover, results suggests that under cross-border banking, bilateral correlations become greater than in the absence of these activities. Overall, results demonstrate sizable spillover effects of cross-border banking in the propagation of shocks and suggest that cross-border banking is an important source of the synchronization of business cycles.

This dissertation consists of four chapters analyzing the effects of heterogeneous and asymmetric information in macroeconomic and financial settings, with an emphasis on short-run fluctuations. Within these chapters, I study the implications these informational frictions may have for the behavior of firms and financial institutions over the business cycle and during crises episodes. The first chapter examines how collateral constraints on firm-level investment introduce a powerful two-way feedback between the financial market and the real economy. On one hand, real economic activity forms the basis for asset dividends. On the other hand, asset prices affect collateral value, which in turn determines the ability of firms to invest. In this chapter I show how this two-way feedback can generate significant expectations-driven fluctuations in asset prices and macroeconomic outcomes when information is dispersed. In particular, I study the implications of this two-way feedback within a micro-founded business-cycle economy in which agents are imperfectly, and heterogeneously, informed about the underlying economic fundamentals. I then show how tighter collateral constraints mitigate the impact of productivity shocks on equilibrium output and asset prices, but amplify the impact of "noise", by which I mean common errors in expectations. Noise can thus be an important source of asset-price volatility and business-cycle fluctuations when collateral constraints are tight. The second chapter is based on joint work with George-Marios Angeletos. In this chapter we investigate a real-business-cycle economy that features dispersed information about underlying aggregate productivity shocks, taste shocks, and-potentially-shocks to monopoly power. We show how the dispersion of information can (i) contribute to significant inertia in the response of macroeconomic outcomes to such shocks; (ii) induce a negative short-run response of employment to productivity shocks; (iii) imply that productivity shocks explain only a small fraction of high-frequency fluctuations; (iv) contribute to significant noise in the business cycle; (v) formalize a certain type of demand shocks within an RBC economy; and (vi) generate cyclical variation in observed Solow residuals and labor wedges. Importantly, none of these properties requires significant uncertainty about the underlying fundamentals: they rest on the heterogeneity of information and the strength of trade linkages in the economy, not the level of uncertainty. Finally, none of these properties are symptoms of inefficiency: apart from undoing monopoly distortions or providing the agents with more information, no policy intervention can improve upon the equilibrium allocations. The third chapter is also based on joint work with George-Marios Angeletos. This chapter investigates how incomplete information affects the response of prices to nominal shocks. Our baseline model is a variant of the Calvo model in which firms observe the underlying nominal shocks with noise. In this model, the response of prices is pinned down by three parameters: the precision of available information about the nominal shock; the frequency of price adjustment; and the degree of strategic complementarity in pricing decisions. This result synthesizes the broader lessons of the pertinent literature. However, this synthesis provides only a partial view of the role of incomplete information: once one allows for more general information structures than those used in previous work, one cannot quantify the degree of price inertia without additional information about the dynamics of higher-order beliefs, or of the agents' forecasts of inflation. We highlight this with three extensions of our baseline model, all of which break the tight connection between the precision of information and higher-order beliefs featured in previous work. Finally, the fourth chapter studies how predatory trading affects the ability of banks and large trading institutions to raise capital in times of temporary financial distress in an environment in which traders are asymmetrically informed about each others' balance sheets. Predatory trading is a strategy in which a trader can profit by trading against another trader's position, driving an otherwise solvent but distressed trader into insolvency. The predator, however, must be sufficiently informed of the distressed trader's balance sheet in order to exploit this position. I find that when a distressed trader is more informed than other traders about his own balances, searching for extra capital from lenders can become a signal of financial need, thereby opening the door for predatory trading and possible insolvency. Thus, a trader who would otherwise seek to recapitalize is reluctant to search for extra capital in the presence of potential predators. Predatory trading may therefore make it exceedingly difficult for banks and financial institutions to raise credit in times of temporary financial distress.

In this thesis I have investigated three aspects of market frictions. Chapter 1 is about financial frictions, i.e. frictional forces prevailing in the financial lending markets and how monitoring and legal fines imposed on banks affect financial fragility. Chapter 2 explores the frictional labor market, i.e. frictional forces that prevent the smooth matching process between employees and employers in labor markets. In this chapter I investigate the sources of fluctuations in labor market volatility. Chapter 3 investigates the asymmetrical information in lending markets and how bankruptcy law could potentially affect this asymmetrical information between a borrower and its lenders. In Chapter 1, I have investigated the implications of legal fines and partial monitoring in a macro-finance model. This primary motivation of this work was the unprecedented level of fines banks faced in recent years. The research in this field is very sparse and this work is one of the few to fill in the void. I have tried investigating the implications of fines and partial monitoring in static and dynamic frameworks. There is partial monitoring in the sense that dubious behavior of intermediaries is not always observed with certainty. Moreover intermediaries can pay some litigation fees to mitigate the punishment for their conduct should they get caught. Several insights can be drawn from introducing such concepts in static and dynamic frameworks. Partial monitoring and legal fines make the incentive constraint of intermediaries more relaxed, in the sense that bankers are required to pledge less collateral to raise fund. This decrease in the asset pledgeability pushes the corporate spread down. In a dynamic set-up due to changes in asset qualities caused by such possibilities, recovery in output and credit become sluggish in response to an adverse financial shock. The dynamic implications of the model for the post-crisis period are investigated. This paper calls for further research to broaden our understandings in how legal settlements interact with banks' behaviors. In Chapter 2 (joint with Elisa Guglielminetti) I have investigated the time-varying property of job creation in the United States. Despite extensive documentation of the US labor market dynamics, evidence on its time-varying volatility is very hard to find. In this work I contribute to the literature by structurally investigating the time-varying volatility of the U.S. labor market. I address this issue through a time-varying parameter VAR (TVP-VAR) with stochastic volatility by identifying four structural shocks through imposing robust restrictions based on a New Keynesian DSGE model with frictional labor markets and a large set of shocks. The main findings are as follows. First, at business cycle frequencies, the lion share of the variance of job creation is explained by cost-push and demand shocks, thus challenging the conventional practice of addressing the labor market volatility puzzle à la Shimer under the assumption that technology shocks are the main driver of fluctuations in hiring. Second, technology shocks had a negative impact on job creation until the beginning of the '90s. This result is reminiscent of the "hours puzzle" à la Gali. In Chapter 3 (joint with Garence Staraci) I provide an additional rationale why creditors include covenants in their contracts. The central claim is that covenants are not only included as a means of shifting the governance from debtors to creditors, but also to potentially address the concerns creditors might have about how the bankruptcy law is practiced. To investigate this claim, I take advantage of the fact that covenants are nullified inside bankruptcy. This fact permits us to show that any change to the bankruptcy law affects the spread through changes that it brings to the contractual structure...

"This thesis consists of three self-contained papers on business cycle fluctuations in the context of the dynamic stochastic general equilibrium framework. The first paper examines how maintenance expenditures affect the occurrence of indeterminacy in a two-sector model economy, motivated by the empirical fact that equipment and structures are maintained and repaired. McGrattan and Schmitz's (1999) survey on `Capital and Repair Expenditures' in Canada indicates that maintenance expenditures account for a substantial fraction of output and new investment. It is shown that the endogenous maintenance expenditures reduce the requirement of the degree of increasing returns to scale to generate sunspot equilibria. In fact, the minimum level of the returns to scale required could be as low as 1.0179. This aspect is important since empirical works such as Basu and Fernald (1997) suggests that returns to scale is close to constant. The second paper addresses the following questions in the context of a neoclassical model of the business cycle: what caused the 1890s and 1907 recessions in the U.S.? In particular, we apply the Business Cycle Accounting method to decompose the economic fluctuation into its sources: productivity, the labour wedge, the investment wedge and the government consumption wedge. Our results suggest that the economy downturn is primarily attributed to frictions that reduce productivity and the wedge capturing distortions in labour-leisure decision. The financial market frictions would have accounted for the drop of the efficiency wedge. A contractionary monetary shock could generate a gap between the marginal rate of substitution and the marginal product of labour. The third paper applies the accounting method proposed by Chari, Kehoe and McGrattan (2007) to identify the primary sources of economic slumps in South Australia from 1990 to 2014. We focus on three major stages: the recession in the early-1990s, the Asian Financial Crisis and the 2008-2012 South Australian slump. Our results show that the efficiency wedge is the primary transmission channel through which the primitive shocks hit the South Australian economy. Shocks such as structural transformation, collapse of motor vehicle industry might have affected the efficiency wedge. Moreover, it is illustrated that infrastructural expenditures are important in increasing the efficiency wedge. This is conformity with the fact that South Australian government is keen to support its development through the Economic Stimulus Plan. Trade openness might also be a contributor." -- abstract, leaves vii-viii.

My dissertation investigates several long-standing issues in macro and international macro, specifically questions related to technological change, financial market imperfections and international risk sharing. The first two chapters analyze these issues in a closed economy model, while the third chapter studies these issues in an open economy model. The first chapter examines the role of credit market imperfections in propagating news of future productivity, both theoretically and empirically. The second chapter investigates the technology-hours debate in an economy buffeted by anticipated technology and fiscal policy shocks. The third chapter, jointly written with Yi Chen, examines the role of a recursive preference developed in Epstein and Zin (1989) in explaining the equity home bias puzzle in an otherwise standard two-country endowment-driven open macro model. Viewed as a whole, my dissertation is an effort to connect technological processes with financial markets in macro models in order to further our understanding of macro phenomena. The first chapter investigates the role of credit market imperfections in shaping the response of the economy to news of future productivity, and proposes an alternative view of how news shocks propagate through the economy. In contrast to the conventional wisdom about news of future productivity - that it generates strong booms in the short run - I develop a novel news-driven business cycle model in which credit market imperfections significantly dampen the short-run response of economic activity to news. To exploit the fact that news of future productivity generates an asymmetry between expected returns and the current financial conditions faced by firms, I model credit market frictions as arising from the agency cost problem. In contrast to the limited enforceability problem, the agency cost problem serves to dampen the short-run response of investment because the desire to increase investment due to the higher expected returns is offset by the endogenous rise in the external finance premium in the absence of an actual rise in productivity. This inertial behavior of investment is in turn transmitted to hours worked and final output through the general equilibrium effect. I then estimate the response of economic activity to news shocks using U.S. manufacturing data and find some suggestive evidence for the credit frictions mechanism presented in the model. The main empirical findings are as follows. First, economic activity exhibits a muted response to news shocks during anticipation periods and therefore tracks, rather than leads, the actual change in productivity. Second, news shocks explain a small fraction of output fluctuations. Finally, industries that are more dependent on external finance or exhibit more volatile idiosyncratic productivity growth appear to have a more dampened response to news shocks in the short run. The second chapter investigates the reliability of using the structural vector autoregression (SVAR) evidence on the response of hours to a technology shock to discriminate between two workhorse business cycle models: standard real business cycle models and sticky price models. Given growing attention to the role of news shocks in the business cycle literature, I evaluate the performance of the SVAR procedure when the true data generating process is driven by news shocks about future technology and fiscal policy. The main results are summarized as follows. First, when the SVAR procedure is applied to the data simulated from an economy with unanticipated shocks to the technology process, the estimated impulse responses have the same sign and qualitative pattern as the true responses. Second, when the SVAR procedure is applied to the data generated from an economy with news shocks to the technology process, the estimated impulse responses generally have a different qualitative pattern from the true responses, and frequently they produce opposite signs. The poor performance of the SVAR procedure largely comes from the anticipation of technology, whereas little is attributed to the anticipation of fiscal policy. Third, if the true data generating process is driven by conventional unanticipated technology shocks, a SVAR researcher can be confident about drawing the conclusion about model discrimination. However, if the true data generating process is driven by news about future technology but a researcher still uses the SVAR procedure based on the conventional information assumption, then the probability that a researcher draws the right conclusion about model discrimination falls dramatically. The third chapter, written jointly with Yi Chen, investigates the role of a recursive preference developed in Epstein and Zin (1989) (EZ) in explaining the equity home bias puzzle, and shows that EZ preferences play a role of increasing the home equity share relative to standard CRRA preferences. This happens because EZ preferences generate a long-run risk hedging demand that contributes to a positive covariance between the relative expenditure and the excess equity return. As a result, the local equity is more likely to be a good asset since it pays off more when investors are willing to spend more. Additional main findings are as follows. First, using the least structural information, we show that the degree of equity home bias depends on the conditional covariance-variance ratio between the relative expenditure and the excess equity return, which nests as a special case the standard CRRA models' implication that the equity home bias depends on the conditional covariance-variance ratio between the real exchange rate and the excess equity return. Second, our model is an infinite-horizon model, while standard trade-cost-based explanations work within two-period models in which portfolio adjustment is impermissible by construction. Thus, our model gets the moment representations for the equity home bias right, while two-period trade-cost-based models assume away portfolio adjustment, thereby overstating the relationship between the real exchange rate and the excess equity return.
