This article examines the role of imperfect competition in determining total factor productivity growth (TFPG) by bringing together a New Empirical Industrial Organization (NEIO) model and the TFPG model of Good, Nadiri and Sickles (1999). Application of the integrated model to 1973–1992 data...

We analyze the incidence of ad valorem and unit excise taxes in an oligopolistic industry with differentiated products and price-setting (Bertrand) firms. Both taxes may be passed on to consumers by more than 100 percent, and an increase in the tax rate can increase short run firm profits (and...

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 general equilibrium models with oligopolistic firms, equilibrium outcomes may depend on the choice of numeraire. When firms have the power to influence prices strategically, different price normalisations entail objective profit functions which are generally not monotone transformations of...

The use of tradable emission rights as environmental policy instruments may affect the conditions for strategic interaction between regulated firms and thus have implications for competition policy. This paper presents an analysis of how, and under what conditions, emission rights can be used...

To the extent that emission permits have been allocated using market mechanisms, this has been done using a sealed-bid auction design, typically with discriminatory prices. However, several authors have recommended the ascending auction format. Basically, two “competing” ascending auction...

We examine the interplay of imperfect competition and incomplete information in the context of price competition among firms producing horizontally- and vertically-differentiated substitute products. We find that incomplete information about vertical quality (e.g., consumer satisfaction) that is...

General equilibrium models of oligopolistic competition give rise to relative prices only without determining the price level. It is well known that the choice of a numéraire or, more generally, of a normalization rule converting relative prices into absolute prices entails drastic consequences...
