Book excerpt: This thesis is a collection of three chapters that study various aspects of the labor force. The first two chapters study how labor markets respond to aggregate influences, when labor market frictions interact with other market features, and a third chapter that evaluates the impact of heterogeneity in households on interest rates. In the first two chapters, I focus on how the post-recession recovery of labor market variables is affected by imperfections in the market. The first chapter investigates the role of on-the-job search in the recovery process of employment, and how labor market power can suppress wages and incentivize against on-the-job search. Labor Market power allows a small number of firms to influence wages and employment in the market, and the suppression of wages persuades workers against expending costly search effort. The second chapter focuses on how the presence of financial frictions can affect the response of labor market variables in a frictional labor market. When bank liquidity is constrained in the event of a downturn, affecting the amount of loans available to firms, firms are unable to purchase the capital input they require to complement labor. This results in firms posting fewer vacancies, and a lower matching rate for workers, which hinders the recovery of employment. The third chapter introduces discount rate heterogeneity in Huggett (1993) and Aiyagari (1994) and evaluates the impact on interest rates.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three chapters. The first chapter concerns the secular changes in the U.S. firm size distribution and firm dynamics. This chapter sets up a quantitative model of firm dynamics with debt heterogeneity to study the implications of changes in real interest rates for the firm size distribution and firm dynamics. It shows that the decline in long-term real interest rates since the early 1980s can account for a significant fraction of the shift in employment shares to large firms as well as the decline in firms per capita and firm entry rates experienced in the U.S. over the same period. In the model, firms endogenously choose financial intermediaries issuing debt with either earnings-based (EBC) or asset-based (ABC) borrowing constraints. The two types of constraints arise naturally from the imperfect enforceability of debt contracts and are in line with recent empirical findings. A decline in real interest rates benefits firms with EBC more because they are not constrained by their assets and can expand more due to increased earnings. Since firms with higher earnings optimally choose earnings-based lending, the decline in real interest rates shifts employment shares to larger firms. Moreover, the growth of large firms crowds out smaller firms and firm entry through general equilibrium effects. The paper tests the mechanism in cross-country data from the OECD and finds a stronger association between the decline in real interest rates and changes in firm dynamics, especially in countries with deeper credit markets. In the second chapter, I study the effects of government regulations on firm dynamism. The impact of government regulations on the economy is a central topic in policy debates. However, due to the endogeneity of regulations and challenges in measuring them, these debates remain contentious. This paper establishes the causal effects of government regulations on firm dynamism by employing a novel shift-share (Bartik) instrument in conjunction with the RegData dataset, which quantifies regulations based on the text of federal regulatory documents. The primary assumption for identification is that, for each sector, the exposure to regulations from different government agencies at the beginning of the period is exogenous to any confounding factors. The findings reveal that government regulatory restrictions significantly increase firm exit rates and discourage the formation of establishments, while having no substantial impact on firm entry. Furthermore, these restrictions contribute to reduced job creation, elevated job destruction, and diminished overall employment. These effects are consistently observed across various age groups. The results lend support to the idea that government regulations can raise production costs for firms and/or enhance the monopolistic power of certain companies. Both mechanisms can diminish the profits of affected firms, leading to increased firm exit rates and reduced labor demand. Additionally, the findings refute the interpretation of regulations as solely serving as entry barriers. The final chapter of the dissertation investigates the labor market outcomes for involuntary part-time workers and their subsequent effects on welfare levels. Through an analysis of survey data, I demonstrate that involuntary part-time workers exhibit reservation wages comparable to those of unemployed workers. This similarity largely stems from parallel wage offers and offer arrival rates. Contrary to previous research, this finding indicates that involuntary part-time workers experience welfare levels akin to unemployed workers. One possible explanation for this discrepancy lies in the methodology of prior studies. Conclusions drawn from earlier research, which primarily focused on the faster transition of involuntary part-time workers into full-time positions compared to other workers, may be flawed. This is because these workers also tend to revert to their previous job types at a faster rate. To further explore the implications of these discoveries, I employ a quantitative search model. The calibrated model supports the assertion that involuntary part-time workers experience welfare levels similar to those of unemployed workers. Furthermore, the model suggests that neither extending unemployment insurance to part-time workers nor enhancing the likelihood that unemployed workers transition to part-time positions would effectively increase the prevalence of full-time employment

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the Great Recession, the interactions between housing, labor and entry highlight the existence of narrow propagation channels between these markets. The aim of this thesis is to shed a light on labor market interactions with firm entry and financial business cycles, by building on the recent theoretical and empirical of DSGE models. In the first chapter, we have found evidence of the key role of the net entry as an amplifying mechanism for employment dynamics. Introducing search and matching frictions, we have studied from a new perspective the cyclicality of the mark-up compared to previous researches that use Walrasian labor market. We found a less countercyclical markup due to the acyclical aspect of the marginal cost in the DMP framework and a reduced role according to firm's entry in the cyclicality of the markup. In the second chapter, we have linked the borrowing capacity of households to their employment situation on the labor market. With this new microfoundation of the collateral constraint, new matches on the labor market translate into more mortgages, while separation induces an exclusion from financial markets for jobseekers. As a result, the LTV becomes endogenous by responding procyclically to employment fluctuations. We have shown that this device is empirically relevant and solves the anomalies of the standard collateral constraint. In the last chapter, we extend the analysis developed in the previous one by integrating collateral constrained firms in order to have a more complete financial business cycle. The first result is that an entrepreneur collateral constraint integrating capital, real commercial estate and wage bill in advance is empirically relevant compared to the collateral literature associated to the labor market which does not consider these three assets. The second finding is the role of the housing price and credit squeezes in the rise of the unemployment rate during the Great Recession. The last two chapters have important implications for economic policy. A structural deregulation reform in the labor market induces a significant rise in the debt level for households and housing price, combined with a substantial rise of firm debt. Our approach allows us to reveal that a macroprudential policy aiming to tighten the LTV ratio for household borrowers has positive effects in the long run for output and employment, while tightening LTV ratios for entrepreneurs leads to the opposite effect.

Book excerpt: The classical treatment of market transactions in economics presumes that buyers and sellers engage in transactions instantly and at no cost. In a series of applications in the housing market, the labour market and the market for corporate bonds, this thesis shows that relaxing this assumption has important implications for Macroeconomics and Finance. The first chapter combines theory and empirical evidence to show that search frictions in the housing market imply a housing liquidity channel of monetary policy transmission. Expansionary monetary policy attracts buyers to the housing market, raising housing liquidity. Higher housing sale rates in turn allow lenders to threaten foreclosure more effectively, because the expected carrying costs on foreclosure inventory are lower. Ex-ante, this makes banks willing to offer larger loans, stimulating aggregate demand. The second chapter uses a heterogeneous firm industry model to explore how the macroeconomic response to a temporary employer payroll tax cut depends on the hiring and firing costs faced by firms. Controversially, the presence of non-convex labour adjustment costs suggests that tax cuts create fewer jobs in recessions. When firms hoard labour during downturns, they do not respond to marginal tax cuts by hiring additional workers. The third chapter develops a theory in which trader career concerns generate an endogenous transaction friction. Traders are reluctant to sell assets below historical purchase price, since realizing a loss signals to the employer that the trader is incompetent. The chapter documents empirically several properties of corporate bond transaction data consistent with this theory of career-concerned traders.

Available in PDF, EPUB and Kindle. Book excerpt: My dissertation is comprised of three papers on the causes and consequences of the U.S. Great Recession. The emphasis is on the role that financial frictions play in magnifying financial shocks, as well as in informing the effectiveness of potential policies. Chapter 1, "Financial Frictions, Investment Delay and Asset Market Interventions," co-authored with Shouyong Shi, studies the role of investment delay in propagating different types of financial shocks, and how this role impacts the effectiveness of asset market interventions. The topic is motivated by the observation that, during the Great Recession, governments conducted large-scale asset market interventions. The aim was to increase the level of liquidity in the asset market and make it easier for firms to obtain financing. However, firms were observed to have delayed investment by hoarding liquid funds, part of which were obtained through the interventions. We construct a dynamic macro model to incorporate financial frictions and investment delay. Investment is undertaken by entrepreneurs who face liquidity frictions in the equity market and a collateral constraint in the debt market. After calibrating the model to the U.S. data, we quantitatively examine how aggregate activity is affected by two types of financial shocks: (i) a shock to equity liquidity, and (ii) a shock to entrepreneurs' borrowing capacity. We then analyze the effectiveness of government interventions in the asset market after such financial shocks. In particular, we compare the effects of government purchases of private equity and of private debt in the open market. In addition, we examine how these effects of government interventions depend on the option to delay investment. In Chapter 2, "Housing Liquidity and Unemployment: The Role of Firm Financial Frictions," I build upon the role that firms' ability to obtain funding plays in the severity of the Great Recession. I focus specifically on how the housing crisis reduced the ability of firms to obtain funding, and the consequences for unemployment. An important feature I focus on is the role of housing liquidity, or how easy it is to sell or buy a house. I analyze how an initial fall in housing market liquidity, linked to rising foreclosure costs for banks, affects labor market outcomes, which can have further feedback effects. I focus on the role that firm financial frictions play in these feedback effects. To this end, I construct a dynamic macro model that incorporates frictional housing and labor markets, as well as firm financial frictions. Mortgages are obtained from banks that incur foreclosure costs in the event of default. Foreclosure costs also affect the ease with which firms can borrow, and this influences their hiring decisions. I calibrate the model to U.S. data, and find that a rise in foreclosure costs that generates a 10% fall in the firm loan-to-output ratio results in a 3 percentage point rise in the unemployment rate. The rise in unemployment makes it more difficult for indebted owners to avoid defaulting on their mortgage. This rise in default, on the order of 20 percent, creates further slack in the housing market by both increasing the number of houses on the market and reducing the amount of buyers. Consequently, there are large drops in housing prices and in the size of mortgage loans. Notably, when firm financial frictions are absent, I observe a counter-factual fall in the unemployment rate, which mitigates the effects on the housing market, and even results in a fall in the mortgage default rate. The results highlight the importance of the impact of the housing market crisis on a firm's willingness to hire, and how firms' limited access to credit magnifies the initial housing shock. In Chapter 3, "Housing Market Distress and Unemployment: A Dynamic Analysis," I add to the contributions of my second paper, and extend the analysis to determine the dynamic effects of the housing crisis on unemployment. In Chapter 2, I focused on comparing stationary equilibria when there is a rise in the foreclosure costs associated with mortgage default. However, a full analysis must also take into account the dynamic effects of the shock. In order to do the dynamic analysis, I modify the model in my job market paper to satisfy the conditions of block recursivity. I do this by incorporating Hedlund's (2016) technique of introducing real estate agents in the housing market that match separately with buyers and sellers. Doing this makes the model's endogenous variables independent of the distribution of households and firms. Rather, the impact of the distribution is summarized by the shadow value of housing. This greatly improves the tractability of the model, and allows me to compute the dynamic response to a fall in a bank's ability to sell a foreclosed house, thus raising the costs of mortgage default. I find that the results are largely dependent on the size and persistence of the shock, as well as the level of firm financial frictions that are present. When firm financial frictions are high, as represented by the presence of an interest rate premium charged to firms, and the initial shock is large, the shock is transferred to firms via an endogenous rise in the cost of renting capital. Firms scale back on production and reduce employment. The rise in unemployment increases the debt burden for households with large mortgages. They can try and sell, but find it difficult to do so because they must sell at a high price to be able to pay off their debt. If they fail, they are forced to default, thus further raising the mortgage costs of banks, further reducing resources to firms, and propagating the initial shock. However, the extent of the propagation is limited; once the shock wears off, the economy recovers to its pre-crisis levels within two quarters. I discuss the reasons why, and what elements would be needed for greater persistence.

Available in PDF, EPUB and Kindle. Book excerpt: 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...

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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "This dissertation consists of three essays concerning the macroeconomic implications of financial market frictions that limit the ability of firms to obtain external finance. Each of the three chapters employs a theoretical macroeconomic model, combined with some empirical analysis, to study unanswered questions in the literature related to the importance of these financial market frictions for the wider economy. The three chapters consider, in turn, the effect of banking crises on investment, output and employment, the implications of financial market frictions for optimal capital taxation, and the effect of banking deregulation on the distribution of income. The first chapter studies the long slumps in output and employment following banking crises. In a panel of OECD and emerging economies, I find that recessions are associated with larger initial drops in investment and more persistent drops in output if they occur simultaneously with banking crises. Furthermore, the banking crises that are followed by more persistent output slumps are associated with particularly large initial drops in investment. I show that these patterns can arise in a model where a financial shock temporarily increases the costs of external finance for investing entrepreneurs. This leads to a drop in investment and a persistent slump in output. Critical to the model is the distinction between different types of capital with different depreciation rates. Intangible capital and equipment have high depreciation rates, leading these stocks to drop substantially when investment falls after a financial shock. If wages display some rigidity, this induces a slump in output and employment that persists for roughly a decade, through the contribution of the decline in equipment and intangibles to declining production and labor demand. I find that this mechanism can account for almost a third of the persistent drop in output and employment in the US Great Recession (2007-2014). In the model, TFP and government spending shocks lead to relatively smaller declines in investment and less persistent drops in output; so the model is also consistent with the more transitory output drops seen after non-financial recessions, where such shocks may have been more important. The second chapter, based on work co-written with Corina Boar, considers the implications of financial market frictions for optimal linear capital taxation, in a setting where the government is concerned with redistribution. By including financial frictions, we emphasize the effect of a new channel affecting the equity-efficiency trade-off of redistribution: taxes affect the allocative efficiency of capital and, ultimately, total factor productivity. We find that high tax rates can be optimal, provided that they are applied to wealth, rather than risky capital. Under plausible parameter values, we find that the optimal tax on risky capital is lower than that on wealth, and roughly in line with current U.S. levels. This suggests welfare gains from taxing wealth at a higher rate than risky capital. The third chapter, based on work co-written with Corina Boar and Yicheng Wang, studies the effect of banking deregulation in the US on the distribution of income, from both a theoretical and empirical perspective. We focus on the effect of the removal of interstate banking and branching restrictions over the 1970-1994 period. We present a theoretical model based on Greenwood and Jovanovic (1990) to illustrate the channels through which this deregulation may affect the income distribution. In the model, income inequality rises after banking deregulation for some values of the parameters--because deregulation decreases the cost of borrowing, which primarily benefits wealthy firm-owners. We empirically estimate the effect of interstate banking and branching deregulation on income inequality by exploiting variations in the timing of deregulation across states. We find that the removal of banking restrictions increased the Gini coefficient by 6 percent in the long run."--Pages ix-xi.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis contributes to the understanding of how socio-economic factors affect the functioning of modern labour markets. It belongs to the strand of academic literature that departs from the standard Walrasian model of the labour market, and considers matching and information frictions to be important determinants of observed labour market phenomena. Within this general framework, this thesis analyses how different forms of agent heterogeneity / socio-demographic identity, productivity, and wealth - affect wage rates and the level of employment in competitive labour markets. The first chapter studies how occupational segregation - the sorting of workers across occupations based on their demographic characteristics - affects the allocation of talent in the labour market. When job vacancy information is transmitted via workers' group-biased social contacts, occupational segregation is found to be a robust equilibrium outcome. The chapter shows that while occupational segregation implies benefits in terms of the job-finding probability of individual workers, it may also engender significant allocative inefficiencies when workers differ in terms of their productivity across occupations. The second chapter examines how heterogeneous workers and firms sort across formal (market-based) and informal (network-based) recruitment channels. When worker and firm productivity are unobservable the two recruitment channels effectively compete in terms of their screening capability. Matching frictions are shown to generate a sorting externality that leads to a multiplicity of equilibrium outcomes, depending on the skill-bias within social networks and the productivity dispersion among workers and firms. The third chapter, co-authored with Damien Puy, examines to what extent variations in wages and employment over the business-cycle can explain the counter-cyclical properties of the income distribution. We show that demand composition effects are an important channel through which aggregate supply shocks are propagated through the economy, and that these have important distributional consequences. In particular, we find income inequality (as measured by the Gini coefficient) to be counter-cyclical. Consistent with empirical evidence, this is shown to be largely due to changes in the level of employment and to a lesser degree to variations in relative factor prices.
