We present a new model of dynamic Bertrand competition, where a quota is treated as an intertemporal constraint rather than as a capacity constraint as is common in the literature. The firm under a quota then can still vary the rates of exports over time provided that its total sales within the...

The apparently unrelenting growth in the GDP-share of health spending (SHS) has been a perennial issue of policy concern. Does an equilibrium limit exist? The issue has been left open in recent dynamic models which take income growth and population aging as given. We view these variables as...

Every finite noncooperative game can be presented as a weighted network congestion game, and also as a network congestion game with player-specific costs. In the first presentation, different players may contribute differently to congestion, and in the second, they are differently (negatively)...

This model extends the keeping up with the Joneses (KUJ) model to incorporate the notion that positional concerns in consumption are best modelled with a reference dependence specification of preferences, as postulated by Tversky and Kahneman (1991) in the context of riskless choice. In line...

This paper investigates the structure of bilateral oligopolies - a simple version of Shapley Shubik games with two types of traders and two commodities. It shows that interior equilibria exist, studies the example of CES utility functions to uncover the relation between the complementarity of...

The market has both a coordination function and an incentive function. The first theorem of welfare economics is all about coordination; the principal-agent model is all about incentives. What is the relative importance of the market in carrying out these two functions? While there has been a...
