Measuring and testing for the systemically important financial institutions

This paper analyzes the measure of systemic importance ∆CoV aR proposed by Adrian and Brunnermeier (2009, 2010) within the context of a similar class of risk measures used in the risk management literature. In addition, we develop a series of testing procedures, based on ∆CoV aR, to identify and rank the systemically important institutions. We stress the importance of statistical testing in interpreting the measure of systemic importance. An empirical application illustrates the testing procedures, using equity data for three European banks.

Ownership structure and risk at Colombian banks

The separation between ownership and the control of capital in banks generates differences in the preferences for risk among shareholders and the manager. These differences could imply a corporate governance problem in banks with a dispersed ownership, since owners fail to exert control in the allocation of capital. In this paper we examine the relationship between the ownership structure and risk for Colombian banks. Our results suggest that a high ownership concentration leads to higher levels of risk.

Mercado laboral calificado en Colombia: Estudio sobre el desequilibrio entre oferta y demanda de trabajo para los años 2020 y 2030

El propósito básico de esta investigación es identificar los desajustes (déficits o superávits) no estructurales entre la oferta y demanda de trabajo en Colombia para los años 2020 y 2030, así como interpretar los hallazgos y proponer elementos de estrategia para las empresas a fin de mitigar los efectos adversos del desajuste sobre su capacidad para atraer y retener talento. El argumento central del proyecto consiste en sostener que en un escenario no mayor a los 10 años la oferta de trabajo calificado en Colombia no será suficiente para (i) equilibrar el mercado y (ii) atender la demanda agregada de trabajo, debido a los cambios generacionales en la realidad demográfica del país, el bajo nivel de preparación de la fuerza laboral disponible y los altos índices de informalidad de los trabajadores y las empresas. Dentro de los resultados se presenta una proyección del comportamiento del mercado de trabajo, así como la magnitud del desequilibrio entre los agentes del mercado. Este estudio aplicado es una propuesta cuantitativa de aproximación a la crisis de talento que se revisa en otros estudios. Es un precedente sólido para profundizar con otros enfoques el futuro del trabajo en Colombia.

Racial and spatial interaction for neighborhood dynamics in Chicago

We look at at the empirical validity of Schelling’s models for racial residential segregation applied to the case of Chicago. Most of the empirical literature has focused exclusively the single neighborhood model, also known as the tipping point model and neglected a multineighborhood approach or a unified approach. The multi-neighborhood approach introduced spatial interaction across the neighborhoods, in particular we look at spatial interaction across neighborhoods sharing a border. An initial exploration of the data indicates that spatial contiguity might be relevant to properly analyse the so call tipping phenomena of predominately non-Hispanic white neighborhoods to predominantly minority neighborhoods within a decade. We introduce an econometric model that combines an approach to estimate tipping point using threshold effects and a spatial autoregressive model. The estimation results from the model disputes the existence of a tipping point, that is a discontinuous change in the rate of growth of the non-Hispanic white population due to a small increase in the minority share of the neighborhood. In addition we find that racial distance between the neighborhood of interest and it surrounding neighborhoods has an important effect on the dynamics of racial segregation in Chicago.
