Determinantes de la cartera del sector financiero en Colombia: un an��lisis basado en un modelo de correcci��n de errores vectorial

En este trabajo se analiza el impacto en la cartera bruta del sector nanciero colombiano ante un choque en las variables macroecon��micas �� viceversa. Lo anterior se realiz�� a trav��s de un modelo de correci��n de errores vectorial (VECM). Inicialmente, los resultados se��alan que existe una relaci��n de causalidad y de largo plazo entre la cartera neta real del sector nanciero, el Producto Interno Bruto, la DTF Real y el ��ndice de la Tasa de Cambio Real. Finalmente, se encontr�� que los impulsos respuesta de las variables mencionadas est��n acordes con la teor��a econ��mica y los hechos estilizados.

Nongenetic inheritance, linguistic competence, prenatal experience and behavior manipulation: recent contributions from behavioral neurobiology and neuropsychology to the explanation of behavior

This article gives an overview of presuppositions and explanations posed by behaviorist psychology (particularly its radical branch), cognitive���nativist sciences (i.e. psycholinguistics and a branch of cognitive psychology) and other disciplines regarding important psychological events such as anxiety, stress, fear, mood states and language. In relation to the discussion of environment versus genetics, contributions from behavioral neurobiology and neuropsychology are added, showing evidence of traits that can be multigenerationally inherited in a non-genetic way, which have an impact thought the life of organisms and on their way of interacting with the environment; ways in which behavior can be altered by recently unsuspected environmental agents or events, and the overlooked role of prenatal experiences in the explanation of behavior. The evidence calls into question presuppositions made by the academic disciplines listed above, and suggests alternative behavior reinterpretations and explanations
