We examine the robustness of R&D and productivity relationship in a panel of 16 OECD countries. We control for fifteen productivity determinants predicted by different theoretical models. Following the advances in non-stationary panel data econometrics, we estimate four variants of thirteen...

A paradox in international trade is that multilateral trade liberalisation has resulted in increases in both the volume of world trade and the amount of foreign direct investment (FDI). This note presents a Cournot duopoly model with two regions, each consisting of two countries, and with an...

A two-country model of the FDI versus export decisions of firms is analysed. The analysis considers both the Cournot duopoly and the Bertrand duopoly models with differentiated products. It is shown that the static game is often a prisoners' dilemma where both firms are worse off when they both...

We examine the dynamics of ideas production and knowledge-productivity relationship in a panel of 19 OECD countries. A new data set of triadic patents is used. We rigorously address the issues of cross-country heterogeneity and endogeneity. Domestic and foreign ideas stocks exert positive but...

This paper analyses how product differentiation affects the volume of trade under duopoly using Shubik-Levitan demand functions rather than the Bowley demand functions used by Bernhofen (2001). The Shubik-Levitan demand functions have the advantage that an increase in product differentiation...

Analyzing a novel dataset we find significantly positive effects of basic, and applied and experimental knowledge stocks on domestic output and productivity for a panel of 10 OECD countries. This letter updates the work of, among others, Mansfield (1980), Griliches (1986) and Adams (1990), at an...

We show that the static duopoly model in which firms choose between exporting and foreign direct investment is often a prisoners' dilemma game in which a switch from exporting to foreign direct investment reduces profits. By contrast, we show that when the game is repeated there is a range of...

This article analyses export taxes in a Bertrand duopoly with product differentiation, where a home and a foreign firm both export to a third-country market. It is shown that the maximum-revenue export tax always exceeds the optimum-welfare export tax. In a Nash equilibrium in export taxes, the...

In the Eaton and Grossman (1986) model of export taxes under Bertrand duopoly, it is shown that welfare in the Nash equilibrium in export taxes is always higher than welfare under free trade for both countries.

In a game between two exporting countries, both countries may be better off if they both delegate to policymakers who maximise tax revenue rather than welfare. However, both countries delegating to policymakers who maximise revenue is not necessarily a Nash equilibrium. The game may be a...
