Valuation of default-sensitive claims under imperfect information

We propose a valuation method for financial assets subject to default risk, where investors cannot observe the state variable triggering the default but observe a correlated price process. The model is sufficiently general to encompass a large class of structural models and can be seen as a generalization of the model of Duffie and Lando (Econometrica 69:633–664, [2001]). In this setting we prove that the default time is totally inaccessible in the market’s filtration and derive the conditional default probabilities and the intensity process. Finally, we provide pricing formulas for default-sensitive claims and illustrate in particular examples the shapes of the credit spreads.      

¿Hay evidencia de ciclo político-económico en el empleo sectorial de México, 1998-2013?

This paper looks for evidence of political-business cycles associated to the presidential elections in the Mexican sectorial employment over the period 1998-2013. By estimating panel data models, and controlling for the effects of the major determinants of employment, no evidence consistent with the predictions of the theoretical opportunistic model is found, i.e. whereas employment shows an expansion before and during the elections periods, the estimates are neither statistically significant nor robust. Furthermore, employment does not experience contractions after the elections or the office taking periods. Notwithstanding, the evidence suggests that employment is positively and negatively affected by output and real wages, respectively.     

Administración del riesgo crediticio al menudeo en México: una mejora econométrica en la selección de variables y cambios en sus características

The early prediction of bad debtors in revolving loans in Mexico is a relevant current issue. The proposed econometric model of behavioral scoring considers the changes in the characteristics of consolidated clients and produces better results than those obtained with methodology used by the CNBV on provisions. The obtained results show the possibility of replacing the current model, minimizing the expected loss and increasing the ROA of Mexican financial institutions in 2.20% complying the methodology and statistical testing criteria according to the Unique Banking Dispositions and the guidelines of Basel II on credit risk.     

Gobierno corporativo,financiamiento y género: un estudio de las pymes emisoras de títulos en los mercados de valores argentinos

The aim of this work is to study corporate governance (CG) in small and medium enterprises (SMEs) from a gender perspective. In particular, we study the participation of women in ownership, management (board and senior management) and external audit in SMEs participating in the Argentinean Securities Market. The results show that participation of women in ownership and in external audit has a significant relationship with financing decisions. However, we do not find evidence of relations among different levels of GC and gender.     

Is socially responsible investment useful in Mexico? A multi-factor and ex-ante review

The present paper continues the firsts reviews made to socially responsible investment in Mexico. We extended these reviews by using a non-parametric multivariate equality test, along with a multi-factor market cap model, and a Monte Carlo simulation. Our results show that the IPCS index, the IPCcomp and the IPC have a statistically equal mean-variance performance, suggesting that this sort of investment style (SRI) is a good substitute of the broad market investment style in the long term. Among the causes of this finding is the fact that the IPCS and the IPCcomp indexes have almost the same large and small cap stock concentration and the IPC index (a large-cap one) is not as diversified and mean-variance efficient as the former.     

The influence of remuneration on the behavior of hospital employees in Brazil

The study aimed to analyze the employee's perception of the remuneration systems in two major hospitals in Brazil, one managed by the government and the other by private investors. The sample considered 109 respondents, out of which 54 were from the private hospital and 55 from the public hospital. After data collection on the sample population, perception of remuneration was associated with occupation, gender, age and experience, as suggested by the Upper Echelons Theory. The results show that remuneration is viewed as an instrument of control and behavior or a learning-inducing mechanism; however, the perceptions of employees working in the health area and administrative area were different. These findings show that the influence of fixed pay is different not only for the employees of both areas, but also in relation to the public and private hospital management. It was found that gender is not a determinant factor of behavior and that there were no differences between younger and older employees as well as between more experienced and less experienced employees with respect to the effect of remuneration on behavior. There were no differences in relation to the type of hospital either. In general, the results emphasize the importance of remuneration as an instrument of control and management, either in the context of public or private organizations.     

Economic integration,economic crises and economic cycles in Mexico

This article analyzes the peculiarity of the dynamics of economic fluctuations of the Mexican economy, within the framework of its integration with the US and Canada; the article demonstrates how the Mexican economy make endogenous the macroeconomic crises from the USA (2001 and 2007), and how the business cycles of both countries became more aligned to each other.Based on the heterodox economic theory of crises and cycles, we check the “empirical law of economic dynamics” of the Mexican capitalist system according to the logic of the multiplier–accelerator theory that allowed us to study the dynamics of business cycles for the period of the study (1993–2013). To do this, we construct and estimate a stationary VAR model and utilize the Granger causality tests and quarterly data.
