We present a new model of dynamic Bertrand competition, where a quota is treated as an intertemporal constraint, rather than as a capacity constraint. The firm under a quota then can still vary the rates of exports over time, provided that its annual sales do not exceed the quota. We show that a quota results in higher prices than a tariff of equal imports. We also find that firms never play mixed strategies in equilibrium, which contrasts from the result of a one-shot game, in which the only equilibrium under a quota is in mixed strategies (Krishna 1989).
