  1. Essays on the interactions of local economies and their macroeconomic implications

    Howard, Gregory (Gregory Liang)
    This thesis consists of three chapters about the spatial aspects of macroeconomics. Chapter 1 argues that local labor demand shocks are amplified by migration. I document that within-U.S. migration causes a large reduction in the unemployment rate of the receiving city, over several years. To establish the causal effect of inmigration, I construct a plausibly exogenous shock by using the outmigration of other places and predicting its destination based on historical patterns. Next, I document that the increase in the demand for housing explains the boom, through two channels. The construction channel occurs because housing is a durable good: hence...

  4. Essays in political economy

    Ornaghi, Arianna; Banerjee, Abhijit V; Finkelstein, Amy; Hanna, Rema; Olken, Benjamin A; Sumarto, Sudarno, 1960-
    This thesis consists of three chapters. The first two chapters explore how different organizational forms, and in particular different hiring and firing practices, affect bureaucracies. In the first chapter, I study how the introduction of merit systems reducing politicians' control over police officers' hiring and firing affected police performance in the 1970s. I exploit population-based mandates for police department merit systems in a regression discontinuity design. Merit systems improved performance: in the first ten years after the reform, the property crime rate was lower and the violent crime clearance rate was higher in departments operating under a merit system than...

  5. Essays in macro and development economics

    Liu, Siyuan (Siyuan Ernest)
    The essays in this thesis study the implications of weak financial institutions for economic growth, allocation of resources, and economic development. Methodologically, the essays draw on a broad range of theoretical and empirical tools from both macro and microeconomics. Many currently and previously developing countries have adopted industrial policies that push resources towards certain "strategic" sectors, and the economic reasoning behind such polices is not well understood. In Chapter 1, I construct a model of a production network where firms purchase intermediate goods from each other in the presence of credit constraints. These credit constraints distort input choices, thereby reducing...

  6. The economics of public libraries.

  7. Essays on the economics of labor markets

    Bartik, Alexander W. (Alexander Wickman)
    This thesis consists of three chapters on the economics of labor markets. Each chapter explores an aspect of the distributional consequences of labor market shocks due to changes in trade, regulations, or technology. The first chapter investigates the extent to which geographic variation in wage growth reflects workers' incomplete arbitrage of changing job opportunities in different locations, industries, and occupations. Without moving costs, worker adjustment to changes in labor demand would eliminate differential earnings effects between directly exposed workers and others in the same skill group. I find evidence against this full-mobility benchmark, estimating that exposure to trade with China...

  11. Essays on the macroeconomic implications of financial frictions

    Ji, Yan, Ph. D. Massachusetts Institute of Technology
    This thesis consists of three chapters on the macroeconomic implications of financial frictions. The first chapter investigates the implications of student loan debt on labor market outcomes. I begin by analytically demonstrating that individuals under debt tend to search less and end up with lower-paid jobs. I then develop and estimate a quantitative model with college entry, borrowing, and job search using NLSY97 data to evaluate the proposed mechanism under the fixed repayment plan and the income-based repayment plan (IBR). My simulation suggests that the distortion of debt on job search decisions is large under the fixed repayment plan. IBR...

  15. Three essays on consumer finance

    Padi, Manisha
    This thesis consists of three chapters on consumer financial contracts. Particularly, this thesis focuses on the regulation and design of markets for financial contracts, and their impact on household financial health. The first chapter studies the role of consumer protection law in the function of mortgage markets in the United States. Consumer protection laws are intended to improve consumer outcomes and are becoming more common, particularly in mortgage markets after the 2008 recession. Little empirical evidence exists about the benefits of these laws to consumer outcomes, relative to the potential compliance costs. This chapter studies the effect of two common...

  17. Evidence aggregation in development economics via Bayesian hierarchical models

    Meager, Rachael
    It is increasingly recognized that translating research into policy requires aggregating evidence from multiple studies of the same economic phenomenon. This translation requires not only an estimate of the impact of an intervention across different contexts, but also an assessment of the generalizability of the evidence and hence its applicability to policy decisions in other settings. This thesis performs evidence aggregation using Bayesian hierarchical models, which both aggregate evidence and assess the true underlying heterogeneity across settings, for applications in development economics. Where necessary, the thesis develops new methods to aggregate evidence on certain measures of evidence currently neglected in...

  19. Essays in the economics of higher education

    Russell, Lauren (Lauren Cathleen)
    This thesis consists of three studies in the economics of higher education. The first two chapters investigate the impacts of mergers of colleges and universities within US higher education markets. Chapter 1 is a case study of five recent consolidations within the University System of Georgia. Using student-level administrative data, I show that four-semester student persistence improves by 7 percentage points for cohorts who matriculate post-consolidation relative to cohorts at similar non-consolidated institutions. These large and significant gains do not come at the cost of increases in spending per student, which is indicative of improved productivity. Moreover, I find no...
