We characterize a class of dynamic stochastic games that we call separable dynamic games with noisy transitions and establish that these widely used models are protocol invariant provided that periods are sufficiently short. Protocol invariance means that the set of Markov perfect equilibria is...

Discrete-time stochastic games with a finite number of states have been widely applied to study the strategic interactions among forward-looking players in dynamic environments. These games suffer from a “curse of dimensionality” when the cost of computing players’ expectations over all...

In the oligopolistic case with symmetric risk aversion coefficient, we determine the conditions under which … (storage) in its competitor’s dams. When there is asymmetry of the risk aversion coefficient, the firm’s hydroelectricity …

Using a dynamic model of capacity accumulation, I examine the relationship between uncertainty about the timing of a new Pigouvian tax and oligopolistic competition. I find that for some market structures uncertainty about the timing of the regulatory change leads firms to increase investment....
