We propose an ARCH model of the TGARCH type with an asymmetric Student's t distribution. It is built using the methodology of Fernandez and Steel (1998) and the traditional TGARCH model developed by Zakoian (1994). The model is used to describe series of stock market returns and to assess the...

We develop a comparative study using the TARCH and EGARCH non-linear econometric models. We use them to describe Mexican stock market returns. We model daily series of returns for 30 stocks and the Stock Market Index (IPC) for the period between December 7, 2005 and August 1, 2011. Most of the...

We develop an investigation regarding the determinants of the stock prices in six Latin American emerging markets (Argentina, Brazil, Chile, Colombia, Mexico and Peru). We test the traditional Ohlson model and an international version of it. The international model includes the Dow Jones index...

We develop an investigation regarding the determinants of the stock prices listed in the Mexican Stock Exchange (BMV). We use the valuation Ohlson model and an extension of it. The Ohlson-Beta model includes the Beta elasticity as an additional explanatory variable. We use time-series and...

We develop a microeconomic model to explain why sanction policies used by developed countries have had ambiguous effects to reduce drug trafficking in developing countries. In the model, a country receives FDI depending on its government effort to reduce drug exports. However, local drug...

We study the decisions that a monopolistic bank takes to achieve risk management and profit objectives. The bank faces liquidity and solvency risks because loans may not be repaid and because unexpected deposit withdrawals may occur. The Asset-Liability-Management (ALM) banking model shows that...

In this study we develop a three-factor model of the term structure of interest rates that includes a market sensitivity parameter. In the model the future short-rate depends on the current short-rate, the short-term mean of the short rate and the current volatility of the short-rate. The...

We analyze the effects of leadership in banking when oligopolistic competition exists in the market of deposits. We assess such effects by comparing the performance of banking systems that only differ on their strategic interactions. Specifically, we compare the outcomes associated to strategies...

We study how banking competition may affect the stability of banking systems. We develop our study by expanding the failure-determinant methodology to include panel-data techniques and by controlling the effects of financial structure and development. We use indicators for 47 countries between...

We study how competition may affect the stability of banking systems. We modify the failure-determinant methodology to include panel-data techniques. We use indicators for 47 countries between 1990 and 1997. The main findings show that banking concentration and foreign ownership are associated...
