This paper explores the implications of Internet peering in the context of a model of competing, vertically integrated Internet Access Providers. We show that if regulation forbids settlement payments between firms, there will be under-investment in capacity and under-pricing of usage, both of...

This paper examines twenty-seven international real estate securities indices from twenty countries and regions for calendar effects. Two methodologies are employed. The first is the standard approach which detects statistically significant anomalies via linear regression of returns. The second,...

In this paper we apply Bayesian methods to estimate a stochastic volatility model using both the prices of the asset and the prices of options written on the asset. Implicit posterior densities for the parameters of the volatility model, for the latent volatilities and for the market price of...

We used a reproductive skew framework to consider the evolution of parental and alloparental effort in cooperatively breeding groups. The model provides the first theoretical treatment of rent payment (the "pay-to-stay" hypothesis) for the evolution of helping behavior of subordinates. According...

This paper analyzes the consequences of multihoming on private and social incentives for compatibility. Multihoming occurs in our model when consumers buy from both of two competing firms so as to capture network benefits. We address whether the ability of consumers to multihome means...

This paper presents a model of competing payment schemes. Unlike previous work on generic twosided markets, the model allows for the fact that in a payment system users on one side of the market (merchants) compete to attract users on the other side (consumers who may use cards for purchases)....

This paper models settlement arrangements between international telecommunication carriers. The FCC in the United States claims these arrangements cost United States consumers billions of dollars annually, largely to subsidize foreign carriers in low-income countries. A model is given which...

In this paper I review the recent paper by DeGraba (2000) that proposes a version of Bill and Keep (called COBAK) as the efficient interconnection regime. I argue while the proposed interconnection regime is suitable for some types of interconnection it would be quite undesirable for others. I...
