Abstract: | A wide variety of papers study the time consistency issues and commitment problems associated with imperfectly competitive durable goods manufacturers who sell their output. Using a simple two-period model the authors show that this sort of commitment problem may occur even if the monopolist produces non-durable output. The model assumes consumers maximize their utility through the choice of a non-durable consumption good and saving through an asset that provides future returns and consumption flow. The analysis indicates that non-durable goods manufacturers with market power will wish to announce future prices that are sub-optimal (dynamically inconsistent) when the period is reached due to the impact on consumers' wealth constraint and current purchasing behavior. Thus, the so-called durable-goods monopoly commitment problem may also occur in non-durable goods industries. The model suggests that any type of intertemporal linkage may lead to time consistency and commitment problems for imperfectly competitive firms. |
