This paper overviews maximum likelihood and Gaussian methods of estimating continuous time models used in finance. Since the exact likelihood can be constructed only in special cases, much attention has been devoted to the development of methods designed to approximate the likelihood. These...

In this paper we check the relationschip between the yields of the Colombian bonds traded in the (secondary) internal market and the yields of the sovereign global securities for the sample period 1999-2001. The hypothesis we maintain is that, under the assumption of capital mobility, it should...

En este documento se construye un Indice de Percepción de Riesgo de los inversionistas institucionales en los mercados industrializados. Este índice se estima con base en un modelo de análisis factorial dinámico, que explora las tendencias comunes de las volatilidades de los retornos de una...

En este documento se utilizan herramientas de análisis de redes tradicionales para describir las características generales de la estructura del Mercado Electrónico Colombiano (MEC). Se encontró que éste está fuertemente concentrado en unos pocos agentes, con bajo nivel de conectividad,...

Las transferencias de fondos que se realizan entre los participantes en un sistema de pagos conforman redes de valor que, por su naturaleza, están expuestas a riesgos financieros de diverso género y, en particular, al potencial de riesgo sistémico. La incidencia que ello tendría sobre la...

The use of equilibrium models in economics springs from the desire for parsimonious models of economic phenomena that take human reasoning into account. This approach has been the cornerstone of modern economic theory. We explain why this is so, extolling the virtues of equilibrium theory; then...

One measure of the health of the Social Security system is the difference between the market value of the trust fund and the present value of benefits accrued to date. How should present values be computed for this calculation in light of future uncertainties? We think it is important to use...

In many democratic countries, the timing of elections is flexible. We explore this potentially valuable option using insights from option pricing in finance. The paper offers three main contributions on this problem. First, we derive a rationally-based mean-reverting political support process...

A simultaneous double auction market with bid and offer cards was utilized in classes on the theory and history of money and financial institutions and occasionally in classes on the theory of games. The prime purpose in using this game was to teach the students how to construct process models...

We examine the link between increases in housing wealth, financial wealth, and consumer spending. We rely upon a panel of 14 countries observed annually for various periods during the past 25 years and a panel of U.S. states observed quarterly during the 1980s and 1990s. We impute the aggregate...
