This paper analyzes some asymptotic results for a new estimator of integrated volatility in a continuous-time diffusion process of high frequency data (used in asset pricing finance). The estimator, which is computationally efficient, is based on the quadratic variation of the second order...

In this paper we test whether volatility in six emerging markets has changed significantly over the period 1976:01-2002:03. This period corresponds to the years of more profound development of both the financial and the productive sides in emerging countries. We use alternative methodologies of...

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...

It’s conceptually attractive to look for connection between performance, HRM and economic situation. How measure epiphenomenon’s impact when we can’t isolate that from global strategy? If casual relations maybe established, event can be interpreted in several ways (e.g. its...

In this paper we examine the connection of microscopic network properties of trading and macroscopic properties of prices. Using intraday trading data from the London Stock Exchange, we are able to track which institutions traded with which and reconstruct the network of exchanged stocks. We...
