R esearchers widely use speedup, efficiency, and scalability1–3 to assess parallel-computing performance. These metrics encourage researchers to use any novel technique to design or improve a parallel system, without paying enough attention to the cost increase that such a technique incurs. However, as national-defense applications are downsizing, commercial applications are the dominant users ...

Using bank level data this paper examines how bank’s specific characteristics and the overall banking environment affect the profitability of commercial domestic and foreign banks operating in the 15 EU countries over the period 1995–2001. The results indicate that profitability of both domestic and foreign banks is affected not only by bank’s specific characteristics but also by financial mark...

Technology selection is a decision making area of major concern to today’s manager. Technologies can create or destroy profits and have the ability to create new industries and transform or destroy existing ones. The dynamics of global business have changed the shape of organisational strategies. Now the focus is on a network rather than a single unit. This change has also affected the technolo...

To date, Peterson and Kern‘s (1996) ―highbrow omnivorousness‖ hypothesis has been examined mainly for the case of musical taste. In this paper we attempt to extend this framework to a relatively unexplored cultural domain, that of television consumption. Using data from the 2001 Eurobarometer we hypothesize that highbrows will be more likely to consume a wide variety of other forms of popular c...

We show that the presence of sufficiently significant switching costs, which are increasing in the degree of product differentiation, generates an equilibrium configuration with maximal differentiation within the framework of a Hotelling model with linear transportation costs. The equilibrium with maximal differentiation offers a formalization of the idea that competing firms have noncooperativ...

We investigate the impact of advertising in a simple static differentiated duopoly model. In order to do that, we compare the situation where the firms compete with two strategic variables – i.e. the prices and the advertising expenditures – with the situation where the firms only compete in prices and do not advertise at all. We characterize in terms of the model parameters the circumstances i...

Corporations and industries use various tactics to obscure the fact that their products are dangerous or deadly. Their aim is to secure the least restrictive possible regulatory environment and avert legal liability for deaths or injuries in order to maximize profit. They work with attorneys and public relations professionals, using scientists, science advisory boards; front groups, industry or...

This paper uses data from an actual fishery to construct a tractable, dynamic model to compare expected profit and its variance, optimal stock size, optimal harvest rate, and optimal fishing effort under different management regimes under uncertainty. The results provide a comparison of instrument choice between a total harvest control and a total effort control under uncertainty, an original m...

Economists and antitrust authorities recognize that firms with market power often raise prices above competitive levels and thus earn monopolistic profits that exceed the competitive cost of capital. In both the U.S. and Europe, this recognition has led antitrust authorities (and courts) to consider profitability evidence when determining whether a firm has market power. In Europe, unlike the U...
