In this paper, we compare ad valorem and specific taxation under heterogeneous demand when a monopolist offers a menu of two-part tariffs. An increase in either tax rate leads to a higher usage fee for all consumers, whereas ...

We study the incentives of drug producers to develop predictive biomarkers, taking into account strategic interaction between drug producers and health plans. For this purpose we develop a two-dimensional spatial framework ...

We consider a two-stage game between two competing Internet service providers(ISPs). The firms offer access to the Internet. Access is assumed to be vertically and horizontally differentiated. Our model exhibits network ...

This paper documents price discrimination by transport companies, revealing their market power. Larger shipments of similar products sharing a container receive lower prices. A trade model with non-linear pricing of ...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities) taking a differential game approach, in which quality is a stock variable. Using a Hotelling ...

We conduct a large-scale intercultural experiment to elicit competitiveness and ask whether individual and gender differences in competitiveness are partially determined by nature. We use being a “lefty” (i.e., having ...

Despite attempts to get around the Jacobian in fitting spatial econometric models by using GMM and other approximations, it remains a central problem for maximum likelihood estimation. In principle, and for smaller data ...
