We investigate the effect of stock discovery on the profits of non-identical oligopolists. We show that a uniform addition to all stocks could harm firms that are originally larger than average. One conclusion that could be drawn from the results is that a new technology that leads to more...

We consider a benchmark static incentive scheme, i.e. a per unit subsidy, that induces a monopoly to produce a target output level. We show that the same output level can be achieved by a continuum of dynamic subsidy rules based on a performance indicator. The subsidy rules require only local...

We model international rivalry between a domestic firm that is going through a leaming-by-doing phase, and a mature foreign rival. We show that the optimal production subsidy for the domestic firm depends on the degree of strategic sophistication of the foreign firm.Optimal production subsidy...

We consider a nonrenewable resource game with one cartel and a set of fringe members. We show that (i) the outcomes of the closed-loop and the open-loop nonrenewable resource game with the fringe members as price takers (the cartel–fringe game à la Salant, 1976) coincide and (ii) when the...

We give a full characterization of the open-loop Nash equilibrium of a nonrenewable resource game between two types of firms differing in extraction costs. We show that (i) there almost always exists a phase where both types of firms supply simultaneously, (ii) when the high cost mines are...

In the dominant firm model, we show that an increase of the fringe's reserves of a nonrenewable resource may lead to a decrease in aggregate discounted social welfare. This happens when the difference between the fringe's extraction cost and the dominant firm's is positive and large enough. We...

Abstract We provide the closed form solution to the Dasgupta-Heal-Solow-Stiglitz (DHSS) model. The DHSS model is based on the seminal articles (Dasgupta and Heal, 1974) and (Solow, 1974) and Stiglitz (1974) and describes an economy with two assets, man-made capital and a nonrenewable resource...

We give a full characterization of the open-loop Nash equilibrium of a non-renewable resource asymmetric game. We show that (i) there almost always exists a phase where both supply simultaneously positive quantities, (ii) when the high cost mine is exploited by a number of firms that goes to...

We revisit the seminal growth model with exhaustible resources, the so called Dasgupta-Heal-Stiglitz-Solow model (DHSS). For this optimal control problem with two state variables, we explicitly characterize the dynamics of all the variables in the model and from all possible initial values of...

We specify and solve a closed-loop dominant firm nonrenewable resource game, with a price-taking fringe. We show that (i) the outcomes of the closed-loop and the open-loop dominant firm nonrenewable resource game (à la Salant 1976) coincide and (ii) when the number of fringe firms becomes...
