Book excerpt: This thesis consists of three chapters pertaining to issues of long-term relationships in labour markets. In Chapter 1, I analyze a model of a two-period advice game. The decision maker chooses to retain or replace the advisor after the first period depending on the first period events. Even though the decision maker and the advisor have identical preferences, this potential replacement creates incentive for the advisor to avoid telling the truth. I show the condition under which the decision maker can find a random retention rule that induces a truthful report from the advisor, and I characterize an optimal retention rule that maximizes the decision maker's expected payoff.Lastly, in Chapter 3, I quantitatively assess wage dispersion and business cycle implications of the model developed in Chapter 2. In terms of wage dispersion, the model with on-the-job search with wage-tenure contracts seems to accommodate sizable frictional wage dispersion. The model, however, generates very small productivity difference among workers, and shows weak evidence that the productivity difference generated by the endogenous variations in incentives is responsible for frictional wage dispersion. In terms of business cycle implications, workers' endogenous effort choice first amplifies the effect of productivity shock on unemployment rate. Second, responses of workers to productivity shocks generate marked difference between the effects of temporary productivity shock and that of permanent shock. Third, the analysis shows the importance of the distributional effect on macroeconomic variables during the transitory periods after a shock.In Chapter 2, I propose a search theoretic model of optimal employment contract under repeated moral hazard. The model integrates two important attributes of the labour market: workers' work incentive on the job and their mobility in the labour market. Even though all workers and firms are ex ante homogeneous, these two factors jointly generate (1) wages and productivity that increase with worker's tenure and (2) endogenous dynamic heterogeneity of the labour productivity of the match. The interaction of these factors provides novel implications for wage dispersion, labour mobility, and the business cycle behaviour of macroeconomic variables.

Book excerpt: This dissertation contributes towards the understanding of the macroeconomic effects of micro-level firm dynamics, in particular firm entry, exit, and innovation activities in driving aggregate economic dynamism and growth. It focuses on the frictions affecting firms in these activities when contracting with their managers and workers, as well as peers, and the corrective role policies can play. The dissertation consists of two chapters. The first chapter, "Restrictions on Executive Mobility and Reallocation: The Aggregate Effect of Non-Competition Contracts", assesses the aggregate effect of non-competition employment contracts, agreements that exclude employees from joining competing firms for a duration of time, in the managerial labor market. These contracts encourage firm investment but restrict manager mobility. To explore this tradeoff, I develop a dynamic contracting model in which firms use non-competition to enforce buyout payment when their managers are poached, ultimately extracting rent from outside firms. Such rent extraction encourages initial employing firms to undertake more investment, as they partially capture the external payoff, but distorts manager allocation. I show that the privately-optimal contract over-extracts rent by setting an excessively long non-competition duration. Therefore, restrictions on non-competition can improve efficiency. To quantitatively evaluate the theory, I assemble a new dataset on non-competition contracts for executives in U.S. public firms. Using the contract data, I find that executives under non-competition are associated with a lower separation rate and higher firm investment. I also provide new empirical evidence consistent with non-competition reducing wage-backloading in the model. The calibrated model suggests that the optimal restriction on non-competition duration is close to banning non-competition. The second chapter, "Knowledge Creation and Diffusion with Limited Appropriation" (joint with Hugo Hopenhayn), studies the interaction of innovation and imitation in driving economic growth. In relation to a series of recent papers in the macro literature have emphasized the interaction between the two forces, we introduce two key elements in considering the incentives to innovate versus imitate. First, we consider frictions in matching innovators and imitators in the process of knowledge diffusion. Second, while most of the recent literature assume that imitators capture the entire surplus from knowledge diffusion, we consider a general bargaining problem between the innovators and imitators in dividing surplus. In a simple one period model, we derive a Hosios condition for the optimal surplus division when firms are ex-ante homogeneous. But we also find that as the degree of firm heterogeneity increases, innovators' share of surplus must decrease to maximize growth, approaching zero for sufficiently large heterogeneity. Our calibrated dynamic model suggests that the optimal share of surplus innovators appropriate should be at the lower end, consistent with weak intellectual property rights.

Book excerpt: The first chapter in this dissertation explores the welfare benefits from relationship banking that arise from the information gleaned by banks through monitoring. If monitoring reveals not only current output, but also new information about future payoffs, lenders can shield themselves from future losses through early termination of lending agreements. In a competitive lending environment, banks shift the benefits of early termination to borrowers through the lending terms, improving not only the overall expected payoff of projects, but also the welfare of borrowers. Numerical results reveal that the benefits of long-term relationships based on the information revealed in monitoring could be substantial. The second chapter explores the inequality implications of automation. Changes in income inequality from advanced automation may stem from two sources. Wages may become more unequal as lower skill tasks that are currently performed by workers are done in the future by computerized capital. With higher relative wage income, high-skill workers will be able to afford investments in capital that are out of reach for low-skill workers, exacerbating income inequality further. Using a general equilibrium model of task-based production, we disentangle the impacts of automation on wage, wealth, and income inequality. Next, using this framework, we discuss policy interventions for addressing inequality, including transfers and taxes on factors, including the political economy implications of such policies.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis studies how contracting frictions affect the outcomes that the public sector or individual agents can achieve. The focus is on situations where the government or the agent lacks commitment on its future actions. Chapter 1, joint work with Juan Xandri, proposes a method to deal with equilibrium multiplicity in dynamic policy games. In order to do so, we characterize outcomes that are consistent with a subgame perfect equilibrium conditional on the observed history. We focus on a model of sovereign debt, although our methodology applies to other settings, such as models of capital taxation or monetary policy. As a starting point, we show that the Eaton and Gersovitz (1981) model features multiple equilibria-indeed, multiple Markov equilibria-when debt is sufficiently constrained. We focus on predictions for bond yields or prices. We show that the highest bond price is independent of the history, while the lowest is strictly positive and does depend on past play. We show that previous period play is a sufficient statistic for the set of bond prices. The lower bound on bond prices rises when the government avoids default under duress. Chapter 2, joint work with Yu Xu, studies debt policy of emerging economies accounting for credit and liquidity risk. To account for credit risk we study an incomplete markets model with limited commitment and exogenous costs of default following the quantitative literature of sovereign debt. To account for liquidity risk, we introduce search frictions in the market for sovereign bonds. In our model, default and liquidity will be jointly determined. This permits us to structurally decompose spreads into a credit and liquidity component. To evaluate the quantitative performance of the model we perform a calibration exercise using data for Argentina. We find that introducing liquidity risk does not harm the overall performance of the model in matching key moments of the data (mean debt to GDP, mean sovereign spread and volatility of sovereign spread). At the same time, the model endogenously generates bid ask spreads, that can match those for Argentinean bonds in the period of analysis. Regarding the structural decomposition, we find that the liquidity component can explain up to 50 percent of the sovereign spread during bad times; when the sovereign is not close to default, the liquidity component is negligible. Finally, regarding business cycle properties, the model matches key moments in the data. Chapter 3, studies the implications of reputation on equilibrium multiplicity in a model of sovereign debt. These models can exhibit multiple equilibria. In the worst equilibrium the government is in autarky. However, in reality, we do not observe the autarkic solution. Motivated by an apparent disconnection between theory and reality, I characterize a lower bound on the utility that the government can obtain for any positive probability that the government is from a commitment type that always repays debts. Chapter 4, joint with Ignacio Presno, studies the optimal risk sharing contract between a risk neutral money lender and an agent that faces Knightian uncertainty about the distribution of her endowment and cannot commit on future transfers. We find that in the optimal contract model uncertainty contributes to increase consumption of the agent over time independently of which shocks have been realized. This differs qualitatively from the case without Knigthian uncertainty.

This book was released on 2013 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation I study optimal borrowing contracts in environments with credit markets imperfections and I explore how several institutions can influence the risk of strategic default. Specifically, in the first and in the second essays I study the efficient information production in credit relationships that are repeated over time, while in the third chapter I study the welfare consequences of different settlement arrangements. Information production in static loan contracts is well understood to be useful for resolving incentive problems and contemporaneously enforce contractual obligations: the value of information in a static costly state verification environment is linked to contemporaneous enforcement of the contractual obligations. In a dynamic environment instead, costly monitoring will survive the provision of dynamic incentives if the information produced by the verification process becomes in part independent of the value of monitoring in enforcing repayments. When the interaction between the lender and the borrower is repeated over time, the information about the position of the players in a particular node of the game tree has value to the lender because it allows to limit history dependence, "reset the clock" and avoid that the evolution of history take the game to a node where incentive-compatible continuation contracts entail punishments so severe to become self-defeating (termination). In the third essay I study a model of trading with limited commitment where collateral is used both to provide incentives and to provide insurance to risk averse traders. In economies with bilateral clearing, collateral (i) serves as insurance against counterparty default risk and (ii) guarantees that agents do not strategically default on their obligations. With central clearing, novation of financial contracts and diversification of counterparty default risk within the CCP strictly dominate collateral as an instrument for insurance. Nevertheless, when the CCP cannot observe the characteristics of its members and prices are not fully informative, the incentive problems associated with central clearing are more severe than those associated with bilateral clearing, leading to higher collateral requirements. Therefore, the desirability of Central Counter Party clearing depends on the resolution of this trade-off.

Book excerpt: In recent decades, households in the US have been facing greater uncertainty in retirement wealth from their employment-based pension plans, as employers move from offering defined-benefit (DB) pensions to defined-contribution (DC) pensions. In Chapter 1, I quantify the extent to which this shift in workplace pension plans affects households' portfolio choices and their risk exposure. Using a life cycle model with two pension plans, stochastic risky asset returns, idiosyncratic earnings shock, and endogenous labor supply, I find that households' risk exposure increases from 3.2% to 6.7% in the DC pension dominant environment while the weight of risky assets in households' portfolio doubles. Compare to DB pensions, DC pensions result in less wealth inequality and higher consumption during retirement absent adverse shocks, but it comes with welfare loss for younger households and old retirees, which illustrates the need of designing possible age-dependent pension policies. When hit by adverse shocks of the same magnitude, households with DC pensions experience 4.3 percentage point larger drop in consumption and take longer to recover, which increases the likelihood of a severe consumption driven recession.In Chapter 2, we propose a methodology for measuring the size and properties of the shadow economy. We use a two-sector dynamic deterministic general equilibrium model with four different trends: hours worked, investment-specific productivity, formal productivity, and shadow productivity. We find that the shadow productivity trend is endogenous, in the sense that it is an exact function of model parameters and the other three trends. We also document that, in order to be consistent with observed (real-world) trend growths, the shadow sector needs to exhibit increasing returns to scale, which is contrary to the standard procedure of imposing decreasing returns to this sector. We apply our methodology to a set of seven Latin American and Asian countries and document several empirical regularities that emerge from our analysis, the most important one being that the volatility of shadow sector output is considerably larger than the one in formal sector output. In Chapter 3, I look at the welfare implications of two federal student loan repayment plans. Specifically, I study how the addition of the newest income-driven repayment plan called Revised-Pay-As-You-Earn, or REPAYE, could affect undergraduate student loan borrowers under the Federal Student Loan Program. I build a dynamic model with stochastic earnings shocks to quantify welfare and wealth distribution implications of the inclusion of REPAYE. Unlike existing works on student loans, I allow agents to switch between Standard and REPAYE plans once during their repayment periods. My results show that adding REPAYE could potentially lead to less wealth inequality across the economy but not so much when including the option of switching between plans. My paper also demonstrates that for undergraduate borrowers, including REPAYE without the possibility of switching would constrain them to only exercise the benefit of REPAYE via the channel of interest savings. However, allowing them to switch between the two plans would enable them to also benefit from REPAYE via the channel of consumption smoothing. Based on computed consumption equivalents from my model, agents are willing to pay 5.15% of annual consumption to have REPAYE added.

This book was released on 2016-01-08 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book retraces the history of macroeconomics from Keynes's General Theory to the present. Central to it is the contrast between a Keynesian era and a Lucasian - or dynamic stochastic general equilibrium (DSGE) - era, each ruled by distinct methodological standards. In the Keynesian era, the book studies the following theories: Keynesian macroeconomics, monetarism, disequilibrium macro (Patinkin, Leijongufvud, and Clower) non-Walrasian equilibrium models, and first-generation new Keynesian models. Three stages are identified in the DSGE era: new classical macro (Lucas), RBC modelling, and second-generation new Keynesian modeling. The book also examines a few selected works aimed at presenting alternatives to Lucasian macro. While not eschewing analytical content, Michel De Vroey focuses on substantive assessments, and the models studied are presented in a pedagogical and vivid yet critical way.
