We present a model of a multi-species fishery and show that (i) consumer preferences for seafood diversity may trigger a sequential collapse of fish stocks under open-access fishery, (ii) the stronger the preferences are for diversity the higher is the need for coordinated multi-species...

Endogenous firm location is analyzed in a discrete two-region-two-firm model of product differentiation. In a non-cooperative game, two regional governments first decide on the imposition (or lifting) of domestic production standards; firms then choose technology (clean or polluting), location...

This paper examines if international trade can reduce total welfare in an international oligopoly with differentiated goods. We show that welfare is a U-shaped function in the transport cost as long as trade occurs in equilibrium. With a Cournot duopoly trade can reduce welfare compared to...

We analyze vertical product differentiation in a model where a good's quality is unobservable to buyers before purchase, a continuum of quality levels is technologically feasible, and minimum quality is supplied under competitive conditions. After purchase the true quality of the good is...

Traditional models of consumer choice assume consumers are aware of all products for sale. This assumption is questionable, especially when applied to markets characterized by a high degree of change, such as the personal computer (PC) industry. I present an empirical discrete-choice model of...

I study the incentives of oligopolists to acquire and disclose information on a common demand intercept. Since firms may fail to acquire information even when they invest in information acquisition, firms can credibly conceal unfavorable news while disclosing favorable news. Firms may earn...

This paper examines how product market competition affects firms' timing of adopting a new technology as well as whether the market provides sufficient adoption incentives. It shows that adoption dates differ not only among symmetric firms but also among markets with Cournot and Bertrand...

An innovative firm chooses strategically whether to patent its process innovation or rely on secrecy. By doing so, the firm manages its rival's beliefs about the size of the innovation, and affects the incentives in the product market. Different measures of competitive pressure in the product...

Barriers to outsourcing that are being currently implemented in the US effectively tax its companies who export jobs through outsourcing. The objective is to raise domestic employment. Given that many of the important international markets where the US has a comparative advantage feature...

I study the influence of minimum quality standards in a partial-equilibrium model of vertical product differentiation and trade in which duopolistic firms face quality-dependent costs and compete in quality and price in two segmented markets. Three alternative standard setting arrangements are...
