This paper explores the effects that collusion can have in newspaper markets where firms compete for advertising as well as for readership.

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 transparency on the consumer side and productivity of firms. We show that more transparent markets are characterized by higher average productivity as firms with low productivity abstain from entering these markets. -- Market Transparency ; Firm...
