This paper presents results from a calibrated welfare model of the UK mobile telephony market which includes many mobile networks; calls to and from the fixed network; networkbased price discrimination; and call externalities. The analysis focuses on the short-run effects of adopting lower...

This Paper characterises the unique Markov equilibrium in the sequential move, finite horizon pricing duopoly with discounting. Simple, short cycles repeat until the last two periods. For discount factors above 0.75488, there are three-period reaction function cycles and below 0.75488,...

We use experiments to analyze what type of communication is most effective in achieving cooperation in a simple collusion game. Consistent with the existing literature on communication and collusion, even minimal communication leads to a short run increase in collusion. However, in a limited...

We find the Nash equilibria for monotone n-player symmetric games where each player chooses whether to participate. Examples include market entry games, coordination games, and the bar-room game depicted in the movie 'A Beautiful Mind'. The symmetric Nash equilibrium involves excessive...

We analyse how sharing rules affect Nash equilibria in Bertrand games, where the sharing of profits at ties is a decisive assumption. Necessary conditions for either positive or zero equilibrium profits are derived. Zero profit equilibria are shown to exist under weak conditions if the sharing...

I develop a model of rent seeking with informational foundations and an arbitrary number of rent seekers, and I compare the results with Tullock's (1980) classic model where the influence activities are "black-boxed." Given the microfoundations, the welfare consequences of rent seeking can be...

According to the favorite-longshot bias observed in pari-mutuel betting, the final distribution of bets overestimates the winning chance of longshots. This Paper proposes an explanation of this bias based on late betting by small privately informed bettors. These bettors have an incentive to...

We study the classical Tullock's model of one-stage contests where the probability of winning is a function of the efforts exerted by the contestants. We show that by a simple non-discriminating rule the contest designer is able to manipulate the outcome of the contest such that the...

In technology-based industries, incumbent firms often license their technology to other firms that will potentially compete with them. Such a strategy is difficult to explain within traditional models of licensing. This paper extends the literature on licensing by relaxing the assumption of a...

This paper analyzes the effects of a potential spillover on technology transfer of a multinational enterprise and on the host country policy. In particular, we examine how both parties’ incentives can be controlled through the ownership structure in an international joint venture. In contrast...
