In this paper I analyse the incentives for governments and producers to act strategically in imperfectly competitive markets when there is Bertrand competition. Strategic behaviour by governments takes the form of distortions to their environmental policy from the first-best rule of equating...

In this Paper, we show that with international externalities, different country sizes, imperfect competition and trade costs, tax competition for mobile firms is efficiency enhancing with respect to the free market outcome. Nonetheless, while the latter entails too many firms in the larger...

There has been much debate recently about the nature of environmental policy that will be set by governments concerned about the competitive advantage their industries might obtain in a world of fierce trade competition. Some claim governments will set environmental policies that are too lax,...

We show that the nature and extent of trade is significantly affected by the pricing policy that firms are allowed to employ. A switch from discriminatory to non-discriminatory pricing (e.g. strict anti-dumping laws) leads to a switch from two-way trade to one-way trade. It is far from true that...

We develop a model with endogeneity in key features of industrial structure linked to heterogeneous cost structures under Cournot competition. We use the model to explore issues related to cross-country differences in industry structure and the impact of globalization on markups and pricing,...

Paul Krugman has clarified the microeconomic underpinnings of both spatial economic agglomerations and regional imbalances at national and international levels. He has achieved this with a series of remarkably original papers and books that succeed in combining imperfect competition, increasing...

In this paper we consider the case for subsidies towards firms which generate R&D spillovers in open economies. We show that in the presence of strategic behaviour by firms many expected results are overturned. Local R&D spillovers to other domestic firms may justify an R&D tax rather than a...

This Paper focuses on two distinct facets of globalization: the decrease in the trade costs of goods and the decline of communication costs between headquarters and production facilities within firms. When the unskilled have about the same wage in the two regions, the decrease of these costs...

Increasing returns in matching between skilled workers and firms create a local thick-market externality when labour markets are geographically segmented. This generates an agglomeration force that can offset the dispersion force due to local competition in a segmented product market. When this...

The World Wide Web was originally a totally English-based medium due to its US origin. Although the presence of other languages has steadily risen, content in English is still dominant, which raises a natural question of how bilingualism of consumers of a home country affects production of web...
