This paper presents a model of international trade in differentiated intermediate goods. Because intermediates are invented through costly R&D investments, employing foreign intermediates implies sharing the return to R&D with the inventor country. We first derive how domestic productivity is...

We estimate international technology spillovers to U.S. manufacturing firms via imports and foreign direct investment (FDI) between the years of 1987 and 1996. In contrast to earlier work, our results suggest that FDI leads to substantial productivity gains for domestic firms. The size of FDI...

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...

This paper provides an analysis of China's trade performance from the 1840s to the present. Its focus is on Shanghai, the world's largest port, which began direct trade relations with Western nations starting in 1843. The paper finds that Shanghai had, and continues to have, an important role in...

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...

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...

China’s recent growth of trade and income is routinely characterized as staggering and the like. We zoom in on Shanghai to see which part is hyperbole and which is not taking the long view. The city is ideal for this‐‐Shanghai held more than half of China’s foreign trade in 1850 and is...

This paper shows that globalization has far-reaching implications for the economy’s fertility rate and family structure because it influences work-life balance. Employing population register data on all births, marriages, and divorces together with employer-employee linked data for Denmark, we...
