Systemic risk is commonly used to describe the possibility of a series of correlated defaults among financial institutions - typically banks - that occur over a short period of time, often caused by a single major event. However, since the collapse of Long Term Capital Management in 1998, it has...

We construct a computer simulation of a repeated double-auction market, designed to match those in experimental-market settings with human subjects, to model complex interactions among artificially-intelligent traders endowed with varying degrees of learning capabilities. In the course of six...

In our paper we investigate how network effects influence the dynamics of oligopoly on mature telecommunication markets. The model covers four categories of agents: telecommunication operators, customers joined into housholds and market regulator. The market state aware firms use reinforcement...

This paper sets out first, to quantify the stabilization gains from commitment in terms of household welfare and second, to examine how commitment to an optimal or approximately optimal rule can be sustained as an equilibrium in which reneging hardly ever occurs. We utilize an influential...

Efficient algorithms for diagnosing influential data points are investigated. Techniques examining potentially influential subsets are considered. Given a list of candidate observations, a new row-dropping algorithm (RDA) computes all possible observation-subset regression models. It employs a...

Population aging threatens to severely destabilize the public finances of a majority of European countries. This unfavorable demographic prospect is usually reinforced by a widespread tendency to anticipate retirement. Reversing this tendency has been identified as a crucial factor to improve...

This paper integrates the literature of Mortgage Design with that of Rotating Savings and Credit Associations (ROSCAs) to present a novel way of mortgage financing (with a zero interest rate) using cooperatives. This mode of financing dissipates credit (default) risk better than the normal mode...

A system of agents interacting in a network with a globalization-polaritation transition is studied in the context of a cultural dissemination model. We consider different types of fields interpreted as forms of mass media acting on the system. Both for autonomous and external fields,...

The last couple of decades has witnessed a growing interest in hedge funds. Academics and practitioners are intrigued by the distinct characteristics of these investment vehicles: hedge funds are flexible with respect to the types of securities they hold and the type of positions they take; they...
