This dissertation consists of three essays that study the economic implications of financial frictions on entrepreneurial investment decision making and aggregate economic performance. The first essay studies investment horizon choice of a distribution of entrepreneurs when a fraction of the financiers within the economy consists of impatient type of lenders. The second essay studies the effects of financial contract enforcement in promoting productive entrepreneurship and economic development. The third essay studies the link between financial development and entrepreneurial capital-labor management. In the first essay, I study the effects of incomplete insurance in financial contracts on risk taking, investment horizon choice and productivity of a distribution of heterogeneous entrepreneurs. I develop a highly-stylized three-period OLG model in which young financiers are heterogeneous in terms of their liquidity needs. As a result, in the model only a fraction of financiers are patient enough to consider their long term lending opportunities. The lending options of financiers are short and long term and any combination of both which result in either short term or long term investment projects undertaken by entrepreneurs. In this setting, equilibrium investment composition (short term vs. long term) and productivity levels of entrepreneurs are determined by their intrinsic entrepreneurial ability distribution, as well as by the fraction of the patient type of financiers in the economy. When productivity improves, entrepreneurial firms increase their capital investment; however, whether they shift to long term oriented projects or not is strongly linked with the liquidity needs of the financiers. Cross-country data shows a positive correlation between a nation's contract enforcement level and its ability to adopt modern technologies. In the second essay of my dissertation, I study the role entrepreneurial incentives play in shaping this empirical observation. I develop and solve a life-cycle model with limited financial contract enforcement, entrepreneurial heterogeneity (ability and financial pledgeability) and technology choice. In the model production processes can be undertaken using either the Traditional or the Modern technology. Depending on the entrepreneurial ability, the modern technology can be more productive relative to the traditional technology, but the former requires a long-term investment making entrepreneur's pledgeability important in his choice. In equilibrium the level of contract enforcement and entrepreneurial characteristics endogenously determine (1) the investment size and (2) the technology choice. Key results of the paper indicate that when financial contract enforcement is weak, the investment size and the intensity of modern technology use of entrepreneurial firms are positively correlated with financial pledgeability. Collateral-building associated with short term investment is important for the results. I calibrate the model to study its quantitative properties. Quantitative experiments illustrate sizeable positive effects of financial contract enforcement on aggregate output and aggregate modern technology adoption for the U.S. economy. Furthermore, counterfactual analysis shows that if financial contract enforcement in Turkey (a low enforcement economy) improves to the U.S. level (a high enforcement economy), output rises by 13-15%; and one third of this change is due to the increase in the rate of modern technology adoption. The third essay in my dissertation provides a quantitative analysis on the effects of firm level financial characteristics in explaining the observed industry-wide productivity heterogeneity in U.S. firm level data. In the first part of the essay, I develop a model in which the interplay between capital and financial market frictions endogenously determine capital-labor ratio decisions of entrepreneurial firms. In this economy capital is costly to rent to some producers due to investment related moral hazard. Therefore, it is beneficial for such entrepreneurs to purchase the capital good instead of renting it. Entrepreneurs can internalize the cost of capital by borrowing in the financial market. However, the amount which can be borrowed is constrained by an entrepreneurs financial market reputation (pledgeability) and his financial asset liquidity (collateral). In equilibrium, firms with lower pledgeability and/or lower liquidity become more labor intensive relative to firms with higher pledgeability and/or liquidity. Distortions to capital rental rates augment the sensitivity of capital-labor choice with respect to firm level financial pledgeability and liquidity. In the second part of the essay, the analytical results are tested in a panel data analysis. Using proxies for "labor intensive production", "financial pledgeability", and "financial asset liquidity" for a large sample of U.S. firms from Compustat North America, I show that low pledgeability and low asset liquidity are associated with labor intensive production. The third part of the essay provides a quantitative analysis. I choose seven major industries in the U.S. economy. For these industries, I show that ability to borrow against financial pledgeability and asset liquidity mitigate the distortionary effects of non-uniform capital rental rates and decrease intra-industry productivity dispersion while increasing industry total factor productivity by quantitatively important proportions. However, there are differential effects of financial pledgeability and financial asset liquidity on aggregate industry performance. My results suggest that the way sectoral firms benefit from the presence of financial pledgeability and asset liquidity depend on sector specific characteristics.

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.

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 studies the effects of firm debt and financing frictions on the macroeconomy. Chapter 1 investigates the role of changes in firms' idiosyncratic risk and their cost of default in driving changes in employment and credit spreads, both over the business cycle and in the cross-section. I use firm-level panel data and a structural model of financial frictions and volatility shocks to assess the effects of shocks to firm volatility and default costs. I find that volatility shocks alone can only generate modest declines in aggregate employment. However, simultaneous shocks to firm volatility and default costs can interact to generate large employment declines. Chapter 2, co-authored with Robert Kurtzman, investigates the role of changes in the allocation of labor and capital between firms in driving productivity dynamics. This chapter presents accounting decompositions of changes in aggregate labor and capital productivity. Our simplest decomposition breaks changes in an aggregate productivity ratio into two components: A mean component, which captures common changes to firm factor productivity ratios, and a dispersion component, which captures changes in the variance and higher order moments of their distribution. We demonstrate that in standard models of production with heterogeneous firms, our dispersion component reflects changes in distortions to the allocation of labor and capital between firms. We find, for public firms in the United States and Japan, that the dispersion component plays a minor role in productivity changes over the business cycle. Chapter 3, co-authored with Robert Kurtzman, investigates the role of debt overhang, an agency problem between firms' equity holders and creditors, in distorting firm growth and aggregate welfare. This chapter addresses this question through the lens of a general equilibrium model of firm dynamics and endogenous innovation in which debt overhang affects the firm innovation decision and subsequent firm growth. The estimated model implies that while the private gains to a firm from resolving debt overhang can be large if it faces sufficient default risk, the social gains to long-run productivity and output are relatively modest. The time-varying distribution of firm default risk suggests social gains may be greater during recessions.

This thesis studies the role of financial frictions in shaping the consumption and investment behavior in China and its implications on rest of the world. The first chapter uses a panel of Chinese individual level data to show that the inability to borrow against future labour income forces a significant portion of individuals to deviate from a smooth consumption path over the life cycle, which they would otherwise follow. Financial frictions also affect the Chinese corporate sector. The second chapter relates China's current account surplus, as well as productivity differential between state-owned (SOEs) and privately-owned enterprises (POEs), to differences in access to finance. I consider an open- economy DSGE model of the Chinese economy with two productive sectors. I model SOEs and POEs as start-ups which need to borrow in order to begin production. Following a policy-induced asymmetric shock to the borrowing constraints, SOEs are on average less productive than POEs. Because of the lower hurdle rate for investment they face, SOEs end up creating more investable assets than POEs, while, due to more constrained credit availability, POEs save more and invest less than SOEs. In aggregate, this simple mechanism implies investment (driven by less productive SOEs) does not keep up with savings (driven by more productive POEs), resulting in a current ac- count surplus. Furthermore, the savings of Chinese POEs owners in search of investable foreign assets put downward pressure on the world long run real interest rate. In the third chapter, I move from China to an international perspective. This chapter constructed a measure of financial frictions for 41 emerging economies (EMs) between 1995 and 2008 in order to shed light on common factors across countries. Finally, Chapter four shows econometrically that financial frictions pose a serious danger to EMs, by reducing long run economic growth, raising the probability of a crisis, and leading to asset bubbles. Consistent with Chapter 2, I confirm that financial fractions can also help explain the current account position of EMs.

In these essays, I study cross-country differences in productivity caused by misallocation of resources. Particularly, I examine the misallocation created by financial frictions as well as that created by entry barriers. In the first chapter, "Financial Frictions and Productivity Losses: Importance of Default-Led Heterogeneity in Collateral and Loan Rates", I develop a model of entrepreneurship with default to quantitatively analyze the impact of financial frictions on total factor productivity (TFP). Default risk justifies the need for collateral. Entrepreneurs are charged higher loan rates if the value of their collateral is low, which favors the wealthy over the poor, regardless of their talent, and discourages poor individuals from self-financing to start or expand their businesses. The close link between deposit rates and loan rates, in most models, is broken. Consistent with empirical evidence, my model can generate a weak self-financing motive while allowing for a highly persistent individual productivity, a challenge for existing models of financial frictions. Financial frictions in my model stem from three different sources: limited enforceability related to the recovery rate of collateral by financial intermediaries; informational frictions related to inefficiencies in financial intermediaries' evaluation of entrepreneurs' default risks; and frictions related to entrepreneurs' expectations of future loan terms. I use machine learning classification techniques to solve the problem financial intermediaries face evaluating entrepreneurs' default risks. My analysis shows sizeable losses from financial frictions, more than 40% in TFP losses for the U.S. if we were to replace its financial markets with a poorly functioning one. Large TFP losses arise as there is amplification between the three sources of financial friction. Without default and heterogeneity in collateral and loan rates, my model would function similarly to a neo-classical model, and there would be a small impact of financial frictions with only a 7% loss in TFP. In the second chapter, "Impact of Entry Costs on Aggregate Productivity: Financial Development Matters", I revisit the question: what is the impact of entry costs on cross-country differences in output and total factor productivity (TFP)? I argue that for the countries with low levels of financial development, the answer is the conventional one in the literature, that higher entry costs cause misallocation of productive factors and lower TFP. However, for countries with reasonably high levels of financial development, the conventional answer does not hold. Motivated by observations on cross-country data, I propose a new theory on the impact of entry costs on TFP. In my mechanism, two competing forces affect TFP when entry cost changes: A wealth-based selection force and a productivity-based selection force. This results in TFP being a hump-shaped function of entry costs. That is, entry costs are not inherently bad for TFP if their target is to deter low productivity individuals from starting businesses. I develop an analytically tractable model of firm dynamics with entry barriers and financial frictions and derive the sufficient conditions for the impact of entry cost on TFP in both wealth- and productivity-based selection phases. In the third chapter, "Firm Entry and Exit in Continuous Time", I develop and analyze a model of firms' entry and exit in a continuous-time setting. I build my analysis based on Hopenhayn (1992) firm dynamics framework and use the continuous-time structure to solve the model. Solving the model in continuous time brings in many advantages, such as lower computational cost and the model's tractability. However, there are some challenges too. One of the major challenges is to have entry cost in the model, i.e., to obtain a Hamilton-Jacobi-Bellman equation that incorporates the entry cost. I use a form of exit cost as the future value of the entry cost to avoid this problem. To do so, I have to keep track of the firms' age distribution in addition to the distribution of the shocks, which makes my model richer than Hopenhayn's (1992). To solve for the joint stationary distribution of the firms, I introduce a simple process for aging and obtain the Kolmogorov forward equation using the age and shock processes. Another methodological contribution is to introduce a way to deal with the Kolmogorov equation in two states with discontinuity and combine them into one equation that governs the state of the economy. The results obtained in this chapter are in line with those reported in Hopenhayn (1992). However, the methods, tools, and the way of approaching the model differs depending on whether I solve the model in discrete or continuous time. The tools and procedures developed in this chapter can easily be extended to other optimal stopping time problems.

Chapter 2 examines asset returns in a production economy where firms face two types of aggregate uncertainty, a productivity shock and a financial shock. Borrowing constraints reduce firms' choice set when facing productivity shocks. Exogenous shocks to the financial market distort firms' optimal production plan due to the constraint on firms' working capital. The amount of systematic risk rises, comparing to the standard business cycle model. I develop a quantitative dynamic stochastic general equilibrium model to evaluate the impact of financial uncertainty on equity risk premium. Calibrated to the US data, the model generates sizable equity premium and stable risk-free rate while matching moments of aggregate economic quantities.

The following essays contribute towards our understanding of nancial crises and development dynamics. The dissertation is composed of three chapters. Chapter one---Lobbying for Capital Tax Benefits and Misallocation of Resources During Credit Crunches Corporations often have strong incentives to exert influence on the tax code and obtain additional tax benefits through lobbying. For the U.S. 2007-2009 financial crisis, I show that lobbying activity intensified, driven by large firms in sectors that depend more on external finance. Using a heterogeneous agent model with financial frictions and endogenous lobbying, I study the aggregate consequences of this rise in lobbying activity. When calibrated to U.S. micro data, the model generates an increase in lobbying that matches both the magnitude and the cross-sector and within-sector variation observed in the data. I find that lobbying for capital tax benefits, together with financial frictions, can account for 80 % of the decline in output and almost all the drop in total factor productivity observed during the crisis for the non-financial corporate sector. Relative to an economy without lobbying, this mechanism increases the dispersion in the marginal product of capital and amplifies the credit shock, leading to a one-third larger decline in output. I also study the long run effects of lobbying. Restricting lobbying implies welfare gains of 0.3 % after considering the transitional dynamics to the new steady state. Chapter 2---Market Power and Aggregate Efficiency in Financial Crises In joint work with Fernando Giuliano, we document that during financial crises in emerging economies, large firms become relatively larger and small firms become relatively smaller. What are the aggregate consequences of the resulting increase in market concentration? We answer this question quantitatively with a model where firms are able to exploit their market power through heterogeneous markups. Financial frictions take the form of a collateral constraint that gets tighter during a financial crisis. We discipline the model using detailed plant-level microdata for Colombia, and analyze the transition dynamics of an economy as it adjust to a credit crunch. We find that when firms are able to adjust their markups in response to a credit shock, the response of aggregate output and productivity is dampened. Variable markups act as a buffer that partially offsets the misallocation triggered by a financial crisis. This follows from adjustments at both the intensive and extensive margins. Chapter 3---Innovation Effort in a Model of Financial Frictions: The Case of Reforms The last chapter is part of an ongoing project to explore the role of innovation as a key ingredient to capture development dynamics of the growth miracles in the East of Asia. During the second half of the last century those economies carried out a rapid dismantling of distortions affecting the size of firms that led to a reallocation of resources. This, together with a slow financial liberalization, created the conditions for sustained increase in per capital income, an increase of investment rates and improvements in aggregate productivity. Using an environment with financial frictions and resource misallocation in a pre-reform economy, Buera and Shin (2013) were able to capture the first two facts. However, the model delivers counterfactual dynamics for aggregate productivity due to the assumption of exogenous firm level productivity. Extending their framework to allow firms to improve their productivity through innovation, I explore the implications of the interaction between financial frictions, resource misallocation and endogenous innovation.
