This dissertation develops three independent yet related frameworks to identify economic mechanisms through which financial frictions affect the aggregate economy over the business cycle and along the path of economic development. There are three chapters in this dissertation. In each chapter, a theoretical model is constructed based on motivating empirical facts, followed by quantitative analyses disciplined and evaluated by data at both the macro- and micro-level. Chapter 1, Financial Frictions and Agricultural Productivity Differences, explores the role of financial frictions in accounting for agricultural employment share and labor productivity differences across provinces in China. A two-sector general equilibrium model with a subsistence consumption requirement and financial frictions is constructed. Limited credit decreases the use of intermediate inputs and increases the use of labor input. As a consequence, workers are trapped in the agricultural sector and agricultural labor productivity is low. Since agricultural employment consists of a large percentage of total employment, aggregate labor productivity is also low. Quantitatively, financial frictions alone explain more than 25% of the observed employment share and productivity differences. Financial frictions amplify the effect of TFP differences on agricultural productivity differences by 30%. Cross-country sectoral value-added per worker differences are large. Value-added per worker is much higher in non-agriculture than in agriculture in the typical country, and particularly so in poor countries. Even though these agricultural productivity gaps (APG) are large, poor countries devote most of their employment to agriculture. Based on a novel data set of value-added at the sectoral level that is comparable across provinces, I find the same patterns across provinces in China. In the second chapter, Credit Constraints, Human Capital and the Agricultural Productivity Gaps, I explore and quantify the role of financial frictions in accounting for these puzzling patterns. A two-sector heterogeneous-agent model with human capital investment, occupational choices and financial frictions is developed. Financial frictions depress human capital accumulation and distort occupational choices of rural households. Quantitatively, our model could account for a substantial portion of the observed cross-province differences in sectoral productivities and the APGs. The financial friction alone could account for 80% of the across-province differences in AGPs. It also explains 1/3 of the sectoral productivity differences and 1/5 of the differences in the agricultural employment share and the aggregate productivity across provinces. In Chapter 3, A Search-Theoretic Model of Capital Reallocation, I investigate how search frictions in the capital market affects capital reallocation across firms and the price of used capital over the business cycles. A tractable dynamic general equilibrium model is developed to account for procyclicality of capital reallocation. Firms are heterogeneous in their productivities and they trade used capital in a market which is subject to search frictions. After idiosyncratic productivity shocks are realized, firms are able to adjust their capital stock to a more favorable level before production. In the booms, the demand of used capital increases and the market tightness of used capital market is small. Hence, capital reallocation is larger and the price of used capital is higher. During the recessions, buyers demand less used capital and the market tightness is large. Consequently, capital reallocation is smaller and the price of used capital is lower. Quantitatively, the model could generate a correlation coefficient between capital reallocation and output that is consistent with the data.

This dissertation is a compilation of three essays on the role of information frictions in macroeconomics. The first essay contributes to the literature on the impact of uncertainty on the business cycle. The cross-sectional dispersion of firm-level outcomes, such as sales growth or stock returns, is markedly countercyclical. Recent papers have framed this fact as evidence that exogenous "uncertainty shocks" are important drivers of business cycles. This paper provides empirical evidence that the co-movement of various dispersion measures with the business cycle is better understood as the economy's endogenous response to traditional first moment shocks - dispersion is the effect, not the cause. It then develops a theoretical model that links the cross-sectional dispersion of micro-level outcomes to the aggregate state of the economy. The mechanism is based on time-varying rational inattention. In bad times, firms pay more attention to idiosyncratic shocks hitting their business environment. More precise micro- level information about the underlying heterogeneity leads to higher dispersion in realized outcomes. In line with the empirical findings, the model generates countercyclical dispersion without relying on exogenous second moment (uncertainty) shocks. The second essay uses survey expectations to assess the microfoundations of an important class of macroeconomic models. Many theoretical macro models try to explain the pervasive nominal and real stickiness in the data by assuming rational decision-making under imperfect information. The behavior of consensus (average) forecasts is consistent with the predictions of these models, which can be seen as supportive empirical evidence for the models' microfoundations (Coibion and Gorodnichenko, 2012). This paper demonstrates, however, that the individual-level data underlying the consensus forecasts are at odds with this interpretation. In particular, I document that individual expectations in the Survey of Professional Forecasters do not pass a very weak test of rational expectations: current forecast revisions are strong predictors of subsequent forecast errors. Information frictions alone cannot explain this pattern. I go on to propose a simple modification of the noisy information framework that allows for a particular form of non-rational expectations: agents may incorrectly weight new information against their prior. I show that this parsimonious model can match the survey data along several dimensions. Using the structure of the model, I estimate the direction and size of inefficiencies in the expectations formation process. I find that in most cases agents put too much weight on their private information, which can be interpreted as overconfidence in the precision of private information. I also show that there is substantial heterogeneity across agents in the deviation from rational expectations, and I relate these differences to observable characteristics. Finally, I discuss potential interpretations of my empirical results and their implications for macroeconomic theory. The third essay explores the potential trade-off between competition and systemic stability in financial intermediation. Why do banks feel compelled to operate with such high leverage despite the risks this poses? Using a simple model, I argue that the degree of competition goes a long way in explaining capital structure decisions. On the one hand, information frictions (adverse selection) render debt a cheaper form of financing than equity. On the other hand, more reliance on debt increases the probability of bankruptcy, which results in the loss of the bank's charter value. The degree of competition affects charter values, and hence changes the way banks balance between these two forces. A panel analysis of European banks' capital structure around the introduction of the euro reveals statistically and economically significant effects consistent with this hypothesis. Banks, in particular smaller banks, decreased their equity ratios after entering the currency area. Complementary evidence suggests that this effect can be attributed to increased competitive pressures boosted by the euro.

This dissertation contains three essays at the interaction between macroeconomics and the financial market, with an emphasis on macroeconomic implications of heterogeneous firms under financial frictions. My dissertation explores the relationships among financial market friction, firms' entry and exit behaviors, and job reallocation over the business cycle. Chapter 1 examines the macroeconomic effects of financial leverage and firms' endogenous entry and exit on job reallocation over the business cycle. Financial leverage and the extensive margin are the keys to explain job reallocation at both the firm-level and the aggregate level. I build a general equilibrium industry dynamics model with endogenous entry and exit, a frictional labor market, and borrowing constraints. The model provides a novel theory that financially constrained firms adjust employment more often. I characterize an analytical solution to the wage bargaining problem between a leveraged firm and workers. Higher financial leverage allows constrained firms to bargain for lower wages, but also induces higher default risks. In the model, firms adopt (S,s) employment decision rules. Because the entry and exit firms are more likely to be borrowing constrained, a negative shock affects the inaction regions of the entry and exit firms more than that of the incumbents. In the simulated model, the extensive margin explains 36% of the job reallocation volatility, which is very close to the data and is quantitatively significant. Chapter 2 investigates firms' financial behaviors and size distributions over the business cycle. We propose a general equilibrium industry dynamics model of firms' capital structure and entry and exit behaviors. The financial market frictions capture both the age dependence and size dependence of firms' size distributions. When we add the aggregate shocks to the model, it can account for the business cycle patterns of firm dynamics: 1) entry is more procyclical than exit; 2) debt is procyclical, and equity issuance is countercyclical; and 3) the cyclicalities of debt and equity issuance are negatively correlated with firm size and age. Chapter 3 studies the equilibrium pricing of complex securities in segmented markets by risk-averse expert investors who are subject to asset-specific risk. Investor expertise varies, and the investment technology of investors with more expertise is subject to less asset-specific risk. Expert demand lowers equilibrium required returns, reducing participation, and leading to endogenously segmented markets. Amongst participants, portfolio decisions and realized returns determine the joint distribution of financial expertise and financial wealth. This distribution, along with participation, then determines market-level risk bearing capacity. We show that more complex assets deliver higher equilibrium returns to expert participants. Moreover, we explain why complex assets can have lower overall participation despite higher market-level alphas and Sharpe ratios. Finally, we show how complexity affects the size distribution of complex asset investors in a way that is consistent with the size distribution of hedge funds.

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 dissertation examines how information and financial frictions impact firms' investment decisions and shape the effectiveness of monetary policy. The first chapter studies the response of high and low credit quality firms to expansionary monetary shocks. According to the findings, high credit quality firms respond to an expansionary shock by increasing their investment, inventory, and sales, whereas low credit quality firms experience a decrease in these variables. Moreover, their financing behavior differs, with high credit quality firms raising funds through equity while low credit quality firms are unable to issue equity or debt. To provide a theoretical explanation for these findings, a simple model is constructed with two types of firms: financially constrained firms and unconstrained firms. Financially constrained firms face a trade-off in allocating their limited funds between wage payments and investment, while unconstrained firms have greater financial flexibility. As a result of an expansionary shock, an increase in wages affects constrained firms disproportionately, leading them to cut their investment to cover the additional labor costs. Furthermore, constrained firms, due to their limited collateral, have to reduce their debt, which aligns with the empirical observations. The second chapter examines the interaction between information and financial frictions and its implications for the investment channel of monetary policy. In a model with inattentive firms facing financial frictions, constrained firms are more attentive to monetary policy as they attempt to avoid financial costs, creating a new channel for financial frictions to affect price rigidity. Since the level of price rigidity is one of the determinants of the outcome of the monetary policy, the model suggests that the investment channel of monetary policy hinges on the interaction between financial frictions and rational inattention. The research provides empirical evidence that supports the predictions of the model. Firstly, the study uses firms' expectation surveys and, taking size as a proxy for financial constraint, finds that smaller firms have more precise nowcasts and forecasts of aggregate variables. Additionally, these firms are more willing to pay for professional forecasts. Secondly, the research employs firms' balance sheet data and a proxy for aggregate attentiveness to demonstrate that higher information rigidity leads to a sluggish and dampened aggregate investment response to monetary shocks, as predicted by the model. The third chapter finds that a contractionary monetary shock would increase the number of defaults and the aggregate liability of defaulted firms in the economy. Using a DSGE model with financial intermediaries, I show that a higher rate of default negatively impacts the balance sheets of banks and leads to a decrease in the supply of credit and a rise in the interest rate of loans. This further increases the cost of production, forcing more firms to file for bankruptcy. The study demonstrates that monetary policy can effectively dampen this amplification mechanism by considering the default rate in the policy rule, thereby ensuring a more stable economic environment

The aim of this paper is to investigate the impact of firms' financial fragility and banks incentives on firms' decision to exit the export market. We draw information from the Prowess database on a large sample of Indian businesses between 2002 and 2017 and we obtain bank data from the Reserve Bank of India. Estimation results indicate that more indebted firms are associated with a high probability of exiting the export market. However, when we focus only on bank borrowing, we find that firms with high levels of bank debt (over total assets) are characterized by a lower probability of abandoning the export sector. By interacting our measures of financial fragility with a state-owned bank dummy, we also show that highly indebted firms borrowing from state-owned banks are associated with an even lower probability of exiting the export market. Finally, when we employ the change in the priority sector regulation to test the causality of our results and avoid endogeneity concerns, we provide evidence that firms borrowing from banks that were missing their priority sector targets are characterized by a significantly lower probability of abandoning foreign markets. The study did not find any significant effect of policy change on firms trying to enter the export market. Using an indirect definition of productivity showed that the policy change did not affect the productivity of the leveraged firms.
