Comparative advertising by one brand against another showcases its merits versus the demerits of the other. In a two-stage game among finitely many firms, firms decide first on how much to advertise against whom. In the second stage, given the advertising configuration, firms compete as Cournot...

In this paper, we discuss the pros and cons of using Data Envelopment Analysis (DEA) to evaluate and enhance the efficiency of natural resource management. The need for a multi-dimensional production frontier approach is sketched, along with examples from other regulated multi-output industries....

On many online auction sites it is now possible for a seller to augment his auction with a maximum or buy-out price. The use of this instrument has been justified in 'one-shot' auctions by appeal to impatience or risk aversion. Here we o.er additional justification by observing that trading on...

The paper considers the owners of the firms as normal investors who want to optimise the return from their investments in accordance with their wealth constraint and the risk of their investment in the firm. The paper tests this theory on a representative sample of Danish companies including...

The European Court of Justice's definition of when a firm has a dominant position has recently come under attack as being meaningless and impossible to measure. We argue that both attacks are wrong, suggest an economic interpretation of domination and propose how it may be measured using modern...

This paper examines the remarkable learning-by-doing in the windmill industry since it emerged in the beginning of the 1980's. Green subsidies for producing electricity by wind power has been a precondition for the rapid growth in the production of windmills. Based on time series of prices of...

This paper studies price signaling in a multi-sender context with two competing firms. Either firm may offer a high or a low quality, but potential customers are, initially, incompletely informed about the quality available at a given outlet. In particular, consumers do not know a priori whether...

We investigate the choice of market variable, price or quantity, of an optimal implicit cartel. If the discount factor is high, the cartel can realize the monopoly profit in both cases. Otherwise, it is optimal for the cartel to rely on quantities in the collusive phase if goods are substitutes...

We survey some of the literature on the effects of improved market transparency on competition in oligopoly. Generally, improved transparency from the perspective of firms makes detection of deviations from tacitly collusive agreements easier, thus facilitating oligopolistic coordination. On the...
