Ranking have become increasingly popular on markets for study programs, restaurants, wines, cars, etc. This paper analyses the welfare implication of such rankings. Consumers have to make a choice between two goods of unknown quality with exogenous presence or absence of an informative ranking....

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,...

We describe a model of fundraising in social groups, where private information about quality of provision is transmitted by social proximity. Individuals engage in voluntary provision of a pure collective good that is consumed by both neighbors and non-neighbors. We show that, unlike in the case...

We analyze sequential and simultaneous price setting under a mixed duopoly with homogeneous products and symmetric quadratic cost functions. When public firm is the follower, there exists the case that the equilibrium price is highest of all timings.

This paper shows that when firms compete on prices in a mixed duopoly, the public firm chooses over-capacity when products are substitutes and under-capacity when products are complements. The private firm always chooses under-capacity. This result is in contrast with that obtained in the...

This paper analyzes a mixed duopoly in which a public firm and a (possibly partially) foreign-owned firm choose their capacity scales before competing in quantities. We show that the private firm chooses over-capacity, as in previous literature, except if it is completely foreign-owned. In this...

We study competition between nonprofit providers supplying a collective service through increasing-returns-to-scale technologies. When providers adopt a not-for-profit mission, the absence of a residual claimant can impede entry, pro- tecting the position of an inefficient incumbent. Moreover,...

This study aims to investigate the impact of privatization on the degree of cooperation and competition in a mixed duopoly market. In this market, one semipublic firm and one private firm determine the level of two types of effort: the cooperative effort made to enlarge the total market size and...
