The paper introduces a framework for studying the hierarchy of growth factors, from deep to more immediate. The specific setting we examine is 18th and 19th century Germany, when institutional changes introduced by reforms and transportation improvements converged to create city growth. We...

Geography shapes economic outcomes in a major way. This paper uses spatial empirical methods to detect and analyze trade patterns in a historical data set on Chinese rice prices. Our results suggest that spatial features were important for the expansion of interregional trade. Geography...

In this paper, we provide aggregate trends in China's trade performance from the 1840s to the present. Based on historical benchmarks, we argue that China's recent gains are not exclusively due to the reforms since 1978. Rather, foreign economic activity can be understood by developments that...

This paper studies the trade of China in the past 150 years, starting from the first opening of China after the Opium War. The main purpose of the paper is to identify what is (and was) China's 'normal' level of foreign trade, and how these levels changed under different trade regimes, from 1840...

This paper examines how international flows of technological knowledge affect economic performance across industries and firms in different countries. Motivated by the large share of the world's technology investments made by firms that are active across borders, we focus on international trade...

How large are spatial barriers to transferring knowledge? We analyze the international operations of multinational firms to answer this fundamental question. In our model firms can transfer bits of knowledge to their foreign affiliates in either embodied (traded intermediates) or disembodied...

This paper estimates the extent to which changing environmental standards have altered patterns of international investment. Our analysis goes beyond the existing literature in three ways. First, we avoid comparing regulations in different countries by using data on inward foreign direct...

Convergence in per capita income turns on whether technological knowledge spillovers are global or local. Global spillovers favor convergence, while a geographically limited scope of knowledge diffusion can lead to regional clusters of countries with persistently different levels of income per...

In this paper, I analyze recent findings by Coe and Helpman (1995) on trade-related international R&D spillovers. A Monte Carlo based robustness test is proposed which compares the elasticity of domestic productivity with respect to foreign R&D estimated by Coe and Helpman with an elasticity...

This paper presents and tests a new model of multinational firms to explain a rich array of multinational behavior. In contrast to most approaches, here the multinational faces costs to transferring its know-how that are increasing in technological complexity. Costly technology transfer gives...
