The basic competitive model with freely available technology is suited for static industries but misleading as applied to major innovative economies for which development of new technologies equals in magnitude around 10% of gross domestic investment. We distinguish free generic technology from...

The unit values of internationally traded goods are heavily influenced by quality. We model this in an extended monopolistic competition framework where, in addition to choosing price, firms simultaneously choose quality. We allow countries to have non-homothetic demand for quality. The optimal...

Much recent research in the economics of information has analyzed the implications of alternative market structures in the presence of qualitative characteristics which cannot be accurately and objectively measured or described. This approach avoids the more basic question of the influence of...

Thereare three points made in this paper. The first is that the question concerning choice of a product line by a monopolist is similar in structure to other adverse selection problems -- and can be analyzed in an elementary way by adapting techniques recently developed for such problems. Such...

The inefficiencies related to endogenous product creation and variety under monopolistic competition are two-fold: one static—the misalignment between consumers and producers regarding the value of a new variety; and one dynamic—time variation in markups. Quantitatively, the welfare costs of...

Should the manufacturer of a product be held legally responsible when a consumer, while using the product, harms someone else? We show that if consumers have deep pockets then manufacturer liability is not economically efficient. It is more efficient for the consumers themselves to bear...

This paper formally analyzes strict liability and negligence in a market setting. The discussion emphasizes the impact of the rules on the market price and on the number of firms in the industry. For simplicity, the damage caused by each firm is assumed to be determined only by that firm's...

This paper compares alternative liability rules for allocating losses from defective products when consumers under- estimate these losses and producers may have some market power. If producers do not have any market power, the rule of strict liability .leads to both the first-best accident...

In what order should a developing country adopt policy reforms? Do some policies complement each other? Do others substitute for each other? To address these questions, we develop a two-country dynamic general equilibrium model with entry and exit of firms that are monopolistic competitors. The...
