This dissertation studies three distinct problems in econometrics. Chapter 1 proposes an adaptive randomization procedure for two-stage randomized controlled trials. The method uses data from a first-wave experiment in order to determine how to stratify in a second wave of the experiment, where the objective is to minimize the variance...
In this dissertation, I cover three different topics in macroeconomics. In Chapter 1, I explore the macroeconomic implications of an increase in business competition and its micro transmission channels. In Chapter 2, I document a rise in savings and cash holdings by non-financial corporations across advanced economies and show that...
This dissertation proposes an oracle efficient estimator in the context of a sparse linear model. Chapter 1 introduces the penalty and the estimator that optimizes a penalized least squares objective. Unlike existing methods, the penalty is differentiable – once, and hence the estimator does not engage in model selection. This...
In the first chapter I introduce the ideas that link selling information to surplus extraction. In my environment the seller may be uncertain about how much the buyer both has already learned before contracting with the seller (belief types) and is able to learn after contracting with the seller (information...
This dissertation explores our understanding of corporate credit ratings. In the first chapter I examine the issue of split ratings. S&P and Moody’s often differ in their initial ratings at bond issuance, producing what is referred to as a split rating. The consensus view in the literature and in practice...
AbstractThis dissertation consists of three papers examining economic issues in developing countries.
The first paper studies how export activity affects prices in domestic consumer markets. Using extensive, spatially disaggregated data from India’s rice markets and exploiting a natural experiment provided by India’s rice export restrictions during 2007-2011, I show that,...
In most markets, consumers of goods and services have vastly more options available to them than they will consider closely. At the point of making a decision, consumers are choosing between only a small subset (i.e., a consideration set) of all possible alternatives. The preceding process that forms these consideration...
In this thesis, I study the effects of spillovers in all-pay auctions and the effects ofregulating wages and hours on the labor market. In the first chapter, I study a model of
asymmetric all-pay auctions with spillovers. In this model, players compete for a prize, and
the sunk effort players...
Many estimation and inference procedures rely on asymptotic approximations for quantities that are unknown to researchers. While often convenient, such approximations can be poor in practice, even when the number of observations is ostensibly large. One response is to eschew asymptotics in favor of finite sample bounds. While remarkable progress...
This dissertation consists of three chapters about education policies in developing countries. The first chapter examines two extrapolation approaches to make out-of-sample predictions using cash transfer experiments in Malawi and Morocco. The second chapter evaluates India's workfare program in terms of targeting efficiency and effects on school enrollment, in comparison...
