This book figures out that network security and informatization have entered a development stage of greater permeation and deeper integration into all aspects of the economy and society. In particular since the 2008 financial crisis, the world's major economies have placed a strategic focus on...

This paper explores the effects of distance as well as subnational and national borders on international and intranational knowledge spillovers through patent citations across the 39 most patent-cited countries and 319 metropolitan statistical areas (MSAs) within the U.S. In contrast to previous...

We estimate foreign wage premiums for every 3‐digit manufacturing industry in China and discover a wide range of premiums both for ‘foreign’ ownership and for overseas Chinese ownership. Foreign ownership generates larger and more prevalent wage premiums than overseas Chinese ownership,...

Using data on academic citations, career and educational histories of mathematicians, and disaggregated distance data for the world's top 1000 math departments, we study how geography and ties affect knowledge flows among scholars. The ties we consider are coauthorship, past colocation,...

How important is the exercise of classical monopsony power against labor for the level of wages and labor's share? We examine this in the context of China and India – two large, rapidly-growing developing economies. Using theory, we develop a novel screen to quantify how wages are affected by...

This paper uses a gravity framework to investigate the effects of distance as well as subnational and national borders in knowledge spillovers. Drawing on the NBER Patent Citations Database, we examine patent citations data at metropolitan level within the U.S. and the 38 largest patent-cited...

This paper presents theory and evidence from highly disaggregated Chinese data that tighter credit constrains force firms to produce lower quality. The paper modifies Melitz's (2003) model of trade with heterogeneous firms by introducing quality choice and credit constraints. The quality sorting...

This paper presents theory and evidence from highly disaggregated Chinese data that tariff reductions induce a country's producers to upgrade the quality of the goods that they export. The paper first documents two stylized facts regarding the effect of trade liberalization on export prices and...
