Model selection is difficult to analyse yet theoretically and empirically important, especially for high-dimensional data analysis. Recently the least absolute shrinkage and selection operator (Lasso) has been applied in the statistical and econometric literature. Consis- tency of Lasso has been...

In this paper, we study the generalization ability (GA)---the ability of a model to predict outcomes in new samples from the same population---of the extremum estimators. By adapting the classical concentration inequalities, we propose upper bounds for the empirical out-of-sample prediction...

In this paper, we study the performance of extremum estimators from the perspective of generalization ability (GA): the ability of a model to predict outcomes in new samples from the same population. By adapting the classical concentration inequalities, we derive upper bounds on the empirical...

This paper studies the impact of home purchase restrictions on China's housing market. We estimate a structural model of household preference for housing, real estate developers' pricing decisions, and equilibrium market outcome in five large cities. By comparing the estimation results from pre-...

This paper studies the impact of the 2011 nationwide cooling measures on China's new home market. We estimate a structural model of household preference for housing, real estate developer's pricing decision and equilibrium market outcome using new home transaction data (during 2008-2017) in four...

For priority-based allocation of indivisible objects to agents with unit demand, when each object has exactly one copy, Abdulkadiroglu et al. (2019) show that the priority-based top trading cycles mechanism is justified envy minimal, in the sense that no strategy proof and Pareto efficient...

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...

CHAPTER 1 (with Joris Pinkse, Margaret Slade, and John Van Reenen): Spillovers in Space: Does Geography Matter?We simultaneously assess the contributions to productivity of three sources of research and development spillovers: geographic, technology and product--market proximity. To do this, we...
