We study the efficient mechanism for downsizing the public sector focusing on adverse selection in productive efficiency. Each agent is assumed to have two type-dependent reservation utilities: the status quo utility in the public sector before downsizing and the utility that he expects to...

We study a retail benchmarking approach to determine access prices forinterconnected networks. Instead of considering fixed access charges asin the existing literature, we study access pricing rules that determinethe access price that network i pays to network j as a linear functionof the...

We study competition among upstream firms when each of them sells aportfolio of distinct products and the downstream has a limited numberof slots (or shelf space). In this situation, we study how bundlinga¤ects competition for slots. When the downstream has k number ofslots, social e¢ ciency...

We study how access pricing affects network competition when consumers'subscription demand is elastic and networks compete with non-linearprices and can use termination-based price discrimination. In the caseof a fixed per minute termination charge, our model generalizes theresults of Gans and...

It is well-known from Innes and Sexton (1993, 1994) that divide-and-conquer contracts allow an incumbent facing a potential entrant to extract more surplus from buyers and hence buyers suffer from the strategy. In this paper, we show that when sellers compete by offering personalized non-linear...

We study how net neutrality regulations affect a high-bandwidth content provider's (CP) investment incentives in quality of services (QoS). We find that the effects crucially depend on network capacity levels. With limited capacity, as in mobile networks, prioritized delivery services are...

The recent subprime crisis and the ongoing Euro zone crisis have generated an enormous interest in the credit rating industry not only among economists but also among average citizens. As a consequence, we have seen an explosion of the economic literature on the industry. The objective of this...

The World Wide Web was originally a totally English-based medium due to its US origin. Although the presence of other languages has steadily risen, content in English is still dominant, which raises a natural question of how bilingualism of consumers of a home country affects production of web...

We analyze competition between interconnected networks when content is heterogeneous in its sensitivity to delivery quality. In a two-sided market framework, we characterize the equilibrium in a neutral network constrained to offer the same quality and assess the impact of such a constraint...
