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...

Empirical studies of firms within industries consistently report substantial heterogeneity in measures of performance such as size and productivity. This paper explores the consequences of joint heterogeneity on the supply side (sellers) and the demand side (buyers) in international trade using...

This paper examines the interdependence between innovation and imports of intermediates, and their joint impact on productivity. We do so by developing a quantitative model with heterogeneous firms and international trade where firms can invest in R&D and source inputs internationally....

How much of China’s recent economic performance can be attributed to market-oriented reforms introduced in the last two decades? A long-run perspective may be important for understanding the process of economic development occurring today. This Paper compares the integration of rice markets in...

I discuss the concept and empirical importance of international technology diffusion from the point of view of recent work on endogenous technological change. In this literature, technology is viewed as technological knowledge. I first review major concepts and discuss the relation of...

When trade costs are of the iceberg type (Samuelson 1952) and markups are independent of trade costs, relative prices across markets are distorted, but relative prices within markets are not. When trade costs depart from the analytically convenient iceberg type, distortion will also occur within...

Convergence in per capita income across countries turns on whether technological knowledge spillovers are global or local in a large class of models. This Paper estimates the amount of spillovers from R&D expenditures in major industrialized countries on a geographic basis. A new data set is...

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

Current orthodoxy suggests that the Industrial Revolution began in Europe because European institutions promoted comparatively high levels of market efficiency. This Paper compares the actual efficiency of markets in Europe and China, two regions of the world that were relatively advanced in the...

In this paper we ask why the gravity model of international trade also work well for foreign direct investment (FDI) flows or multinational production (MP). We propose a model of trade and horizontal FDI, where the subsidiary is allowed to source inputs from the headquarters. Under certain...
