In this paper I emphasize the contribution of technical change towards productivity growth in explaining the relative East Germany-West Germany performance during the post-world war II era 1955-95.

In this paper, I analyze recent findings by Coe and Helpman (1995) of trade-related international R&D spillovers. I show generally that randomly created bilateral trade shares also give rise to large estimated international R&D spillovers; often, in fact, to larger estimated spillover effects...

This paper studies the role of trade, both domestically as well as internationally, as a channel of technology transmission.

Examining the accuracy of the monopolistic competition theory's predictions for import volumes, we assess whether this theory accounts for the empirical success of the gravity equation. Since certain factor-endowment based theories have the same prediction for import volumes, we employ...

We present a model of R&D-driven growth which predicts that technology, in 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 from...

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. I first derive a relation of how domestic...
