sorting of US immigrants, and factors that contribute to China's export growth. Chapter

had the U.S. shifted to a skill-based immigration system. Chapter 2 builds a multi-sector

spatial general equilibrium model featuring heterogeneous rms and workers endogenous location

choice, to quantify for China's export surge during 1990-2005. Chapter 3 studies

factors that determine the occupation sorting of US immigrants.
