This article explores the propensity to patent in the light of the disclosure effect. Unlike earlier approaches concerned with the patenting decision, we take into account that a disclosure effect may decrease the merits of patenting by facilitating inventing around the patent for competitors....

We analyze the strategic protection decision of an innovator between a patent and secrecy in a setting with horizontally differentiated products. By introducing the patenting decision into the well known circular city model, the impact of the disclosure requirement linked to a patent application...

This paper introduces price-dependent individual demand into the circular city model of product differentiation. We show that for any finite number of firms, a unique symmetric price equilibrium exists provided that demand functions are not too convex. As in the case of unit demand, the number...

This paper studies the relationship between horizontal product differentiation and the welfare effects of third-degree price discrimination in oligopoly. By deriving linear demand from a representative consumer's utility and focusing on the symmetric equilibrium of a pricing game, we...

In this paper we empirically investigate the theoretical results obtained in Zaby (2009). From the theoretical model, which introduces the decision to patent into a setting with horizontally differentiated products we deduce several hypotheses and test these empirically. We find that the...

For a market of horizontal product differentiation, the paper examines the effects of the level of competition on the firm's decision between a product and process innovation. When firms have to choose between the two types of innovation, it is demonstrated that both firms undertake the product...

We introduce a cost of location into Hotelling’s (1929) spatial duopoly. We derive the general conditions on the cost-of-location function under which a pure strategy price-location Nash equilibrium exists. With linear transportation cost and a suitably specified cost of location that rises...

In this paper, we analyze the equilibrium amount of entertainment in news coverage of newspapers and television stations. We find that a shift in the inclination to read, expressed by a shift in the (psychological) distance costs, induces both media outlets to incorporate more entertaining...

We analyze the effects of consumers' limited attention on welfare in a model of horizontal product differentiation. We present a novel approach of modeling limited attention: an attention radius. Each consumer only notices goods that are within her attention radius, i.e., goods that are...
