Chapter 1: Nonparametric Identification of Insurance Models with Multidimensional Screening (with Isabelle Perrigne and Quang Vuong)This chapter studies the identification of an insurance model with multidimensional screening, where insurees are characterized by risk and risk aversion. The model...

Endogeneity and misspecification of models are two main concerns in structural estimation, which usually involves the optimal choices of economic agents with unobservable characteristics. In estimating production functions, input variables are endogenous because input decisions depend on...

Essay 1: Integrated Conditional MomentTest for Parametric Conditional Distributions (with Herman J. Bierens)This paper extends the Integrated Conditional Moment (ICM) test for the functional form of nonlinear regression models to tests for parametric conditional distributions. This test is...

This study assesses the impact of government shareholding on corporate performance using a sample of 643 non-financial companies listed on the Chinese stock exchanges. In view of the controversial empirical findings in the literature and the limitations of the least squares regressions, we adopt...

In this thesis, we study nonparametric identification of first-price auction models and propose a semi-nonparametric simulated integratedmoment estimation method to recover the underlying value distribution.In the first essay, we investigate the nonparametric identification of the first-price...

This dissertation explores three issues regarding mutual funds. The first chapter examines the ability of government bond fund managers to time the market, based on their holdings of Treasury securities during the period 1997-2006. We find that, on average, government bond fund managers exhibit...

It is unrealistic to conceive that economic variables or relationships follow a statistical law in which moments or parameters are kept constant over time. The focus of this dissertation is on model specification and testing of time series that are subject to gradual or sudden structural changes...

My dissertation contributes to auction studies. It analyzes the bidding behavior in multi-round auctions. It is motivated by an interesting multi-round feature observed in the procurement auctions held by the Indiana Department of Transportation (INDOT hereafter), which adopts secret reserve...

Why do some sellers auction their goods, while other sellers post a fixed price? My dissertation investigates this question using theoretical, empirical, and experimental methodologies. The first chapter takes the competitive structure of the market as given and examines how the probability that...

This dissertation studies the distributions of treatment effects in switching regimes models (SRMs). First, we propose a general class of SRMs and provide simple estimators of average treatment effects. Second, we establish sharp bounds on the joint distribution of potential outcomes and the...
