We establish the following stylized facts: (1) Exports are characterized by Big Hits, (2) the Big Hits change from one period to the next, and (3) these changes are not explained by global factors like global commodity prices. These conclusions are robust to excluding extractable products (oil...

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...

We present a model of R&D-driven growth which predicts that technology, in the form of product designs and created through R&D investments, is transmitted to other domestic and foreign sectors by being embodied in differentiated intermediate goods. Empirical results are presented employing data...

Economists emphasize two channels through which import liberalization affects productivity, one operating between and the other within firms. According to the former, import competition triggers market share reallocations between domestic firms with different technological capabilities...

While there is general agreement that technology differences must figure prominently in any successful account of the cross-country income variation, not much is known on the source of these technology differences. This paper examines cross-country income differences in terms of factor...

In this paper we emphasize the contribution of technical change, broadly defined, towards productivity growth in explaining the relative East Germany-West Germany performance during the post-World War II era. We argue that previous work was excessively focused on physical capital investments...

This paper examines the evidence on technology diffusion through trade in differentiated intermediate goods. Because intermediates are invented through costly research and development (R&D) investments, employing imported intermediates implies an implicit sharing of the technology that was...

We study the importance of technology and institutions in determining the size of markets in five different countries and fifteen different German states. The setting of 19th century Europe presents a unique opportunity to address this issue, since it witnessed fundamental change in both...

We assemble a dataset on technology adoption in 1000 B.C., 0 A.D., and 1500 A.D. for the predecessors to today's nation states. We find that this very old history of technology adoption is surprisingly significant for today's national development outcomes. Although our strongest results are for...
