Consider the case where one agent controls all assets. One would expect that strong substitutabilities among assets, would help trade, as the seller would value the additional units less.

The Internet in its current form relies on extensive cooperation between network operators to ensure the integrity and security of its core infrastructure. Here we describe how routing registries can be used to improve the security of the Internet infrastructure in general and the BGP routing protocol in particular. Routing registries can be used to generate accurate prefix filter lists as well...

Argumentation theory is considered an interdisciplinary research area. Its techniques and results have found a wide range of applications in both theoretical and practical branches of artificial intelligence, education, and computer science. Most of the work done in argumentation use the on-line textual data (i.e. unstructured or semi-structured) which is intractable to be processed. This paper...

The present paper investigates the portfolio allocation decisions of an investor with infinite horizon when available financial assets differ in their degrees of liquidity. A model with risk neutral agents allows us to endogenously determine the liquidity premium. With risk averse agents, we develop a nontrivial portfolio allocation problem, which enables us to calculate the demand for an illiq...
