Cross-country variability in regulatory frameworks, industrial policy, physician/pharmacy autonomy, brand/generic distinctions, and in the practice of medicine contributes to ambiguous interpretations of pharmaceutical cost comparisons. Here we report cross-country comparisons that: (i) focus on...

We develop a model of vertical innovation in which firms incur a market entry cost and position themselves in the quality space. Once established, firms compete monopolistically, selling to consumers with heterogeneous tastes for quality. We establish existence and uniqueness of the pricing game...

We estimate a dynamic profit-maximization model of a fish wholesaler who can observe consumer characteristics, set individual prices, and thus engage in third-degree price discrimination. Simulated prices and quantities from the model exhibit the key features observed in a set of high quality...

The existing tax policies towards gasoline and diesel cars in the European countries provide a unique opportunity to analyze intertemporal investment aspects in consumer behavior and quality-based price discrimination aspects in manufacturer pricing behavior. We develop an econometric framework...

We evaluate behaviour-based price discrimination from an antitrust perspective by focusing on an industry with inherited market dominance. Under horizontal differentiation behaviour-based pricing does not by itself lead to persistence of dominance unless the dominant firm is protected by...

We consider an incumbent firm and a more efficient entrant, both offering a network good to several asymmetric buyers. The incumbent disposes of an installed base, while the entrant has a network of size zero at the outset, and needs to attract a critical mass of buyers to operate. We analyze...

We propose a heteroscedastic regression model to identify the determinants of the dispersion in interest rates on loans granted to small and medium sized enterprises. We interpret unexplained deviations as evidence of the banks’ discretionary use of market power in the loan rate setting...

A firm must decide whether to launch a new product. A launch implies considerable fixed costs, so the firm would like to assess downstream demand before it decides. We study under which conditions a potential buyer would be willing to reveal his willingness to pay under different pricing...

An economy consists of many duopolistic markets. Firms must earn normal profits in the long run if they are to survive. Normal profits are interpreted as the long-run limit of average profits in the whole economy. We adopt the aspiration based model of firm behaviour, and link it to the economy...

After some decades of relative oblivion, the interest in the optimality properties of monopolistic competition has recently re-emerged due to the availability of an appropriate and parsimonious framework to deal with firm heterogeneity. Within this framework we show that non-separable utility,...
