We analyze the trade-off between monopoly and competition in matching markets. Intermediaries use prices to sort agents on one side of the market, while, on the other side, they rely solely on an imperfect screening technology. The socially efficient outcome is characterized by an optimal quality provision and an efficient market coverage: matched agents are matched assortatively and all agents...

The Internet provides an unprecedented capability for sellers to learn about their customers and offer custom products at special prices. In addition, customization is more feasible today because of advances in manufacturing technologies that have improved sellers’ manufacturing flexibility. We first develop a model of product customization and flexible pricing to incorporate the salient roles ...

The issue that this paper addresses is whether we live in a network society and what spatial implications networking has for society. A network is the inner structure of a self-organising system comprised of parts, their relationships/interactions and the patterns that emerge from the interactions. Space is made by all internal structures of a system that are delimited by a system border from a...

In Neotropical wet forests several species of omnivorous, resource-defending ants, live and forage in close proximity to one another. Although the forest floor is heterogeneous in microhabitat and food quantity, little is known about the impact of microhabitat and food variation upon resource monopoly among ants. We investigated how food type and microhabitat influence food monopoly in resource...

This paper studies the value and optimal timing for investment in finite-lived monopolies, extending the literature on real option games by considering the cases of random and certain-lived monopolies. Under these settings, firms face the risk of demonopolization, that can occur as a random or a certain event. We show that these new settings produce significantly different results when compared...
