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...

The Zollverein was arguably the most important free-trade agreement of the 19th century. This paper investigates the economic impact of the Zollverein on trade in Germany. Although 1834 is the official date of the Zollverein's establishment, member states in fact joined in a non-random sequence...

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...

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...

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 a¢ liates in either embodied (traded intermediates) or disembodied...

This paper uses a case study approach to explore the effects of NAFTA and GATT membership on innovation and trade in the Mexican soaps, detergents and surfactants (SDS) industry. Several basic findings emerge. First, the most fundamental effect of NAFTA and the GATT on the SDS industry was to...

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

We estimate international technology spillovers to US manufacturing firms via imports and foreign direct investment (FDI) between the years 1987-96. In contrast to earlier work, our results suggest that FDI leads to significant productivity gains for domestic firms. The size of FDI spillovers is...

In the wake of falling trade costs, two central consequences in the importing economy are, first, that stronger competition through increased imports can lead to market share reallocations among domestic firms with different productivity levels (selection). Second, the increase in imports might...

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...
