This paper analyzes the interplay between compatibility and product design decisions in a symmetric software duopoly with network effects. We show that suppliers do not always offer differentiated product designs and compete within the market. Rather, when ever both the significance of the...

This paper studies the effects of different income transfers on individual welfare, in both marriage and divorce situations, and on family decisions. We assume three generations within the family. We develop a sequential game that, in a first stage, determines the optimum level of the transfer...

Democratic countries with substantial inequality and where people believe that success depends on connections and luck induce political support for high tax rates and generous welfare states. Traditional wisdom is that such policies harm the economy, but there is not much evidence that countries...

Strong growth in disposable income has inflated consumption to unprecedented, but not sustainable levels. In this process consumer behavior has been changing. To explain the driving forces of this development, the paper introduces a theory of evolving consumer preferences that is molded in an...

I study the influence of minimum quality standards in a partial-equilibrium model of vertical product differentiation and trade in which duopolistic firms face quality-dependent costs and compete in quality and price in two segmented markets. Three alternative standard setting arrangements are...

A quota on foreign competition will generally lead to quality-upgrading (downgrading) of the low-quality (high-quality) firm, an increase in average quality, a reduction of quality differentiation, and a reduction of domestic consumer surplus, irrespective of whether the foreign firm produces...

In a model of vertical product differentiation, duopolistic firms face qualitydependent costs and compete in quality and price in two segmented markets. Minimum quality standards, set according to the principle of Mutual Recognition, can be used to increase welfare. The results of the one-shot...

Hospital markets are often characterised by price regulation and the existence of different ownership types. Using a Hotelling framework, this paper analyses the effect of heterogeneous objectives of the hospitals on quality differentiation, profits, and overall welfare in a price regulated...

In this paper, I compare two-part tariff competition to linear pricing in a vertically differentiated duopoly. Consumers have identical tastes for quality but differ in their preferences for quantity. The main finding is that quality differentiation occurs in equilibrium if and only if two-part...

We analyze the effects of accidents and liability obligations on the incentives of car manufacturers to monopolize the markets for their spare parts. We show that monopolized markets for spare parts lead to higher overall expenditures for consumers. Furthermore, while the manufacturers invest...
