The firmly established evidence of right-skewness of the firms’ size distribution is generally modelled recurring to some variant of the Gibrat’s Law of Proportional Effects. In spite of its empirical success, this approach has been harshly criticized on a theoretical ground due to its lack...

Colombia experienced a deep recession in 1999-2003. Growth slowed by 4.2%,and investment by 34.6%. Was the severity of the recession due to a ¯nan-cial accelerator mechanism µa la Bernanke, Gertler, and Gilchrist (1999)? Toanswer this question, this paper estimates a dynamic stochastic general...

En este trabajo se proponen fechas precisas para los ciclos de negocios ocurridos entre 1980 y 2007 a la vez que se identifican las fases de auge y recesión. Para ello, se utiliza la metodología de Bry y Boschan (1971). Adicionalmente, se identifican algunos hechos estilizados un año antes de...

Empleando un modelo de equilibrio general dinámico y estocástico para una economía pequeña y abierta con imperfecciones y rigideces en el sector no transable calibrado para Colombia, se estudia la conveniencia de que la autoridad monetaria fije como medida de inflación objetivo en su...

Los ciclos económicos colombianos de la segunda mitad del siglo XX implicaron considerables va-riaciones en los agregados reales de la economía. A partir de un modelo con tecnología de produc-ción AK y una función de producción de bienes de capital, que presenta retornos decrecientes para...

The Laboratory of Forestry economics (LEF) was created in 2000 as a joint research unit of the French Institute of Forestry, Agricultural and Environmental Engineering (ENGREF) and the National Institute of Agronomic research (INRA). The mission of the LEF is to conceive, develop, and transfer...

The real wage is acyclical. This fact is inconsistent with standard theories which assume a single shock drives the cycle and predict either a strong pro or countercyclical real wage. This paper tests the hypothesis that the real wage is acyclical because there are several shocks, some with...

We set up a standard small open economy business cycle model driven by government spending shocks, neutral productivity (TFP) shocks, and investment-specific shocks. The model is calibrated to quarterly Canadian data and its predicted moments and sample paths are compared with their Canadian...

The recent empirical evidence documenting the presence of asymmetries in business cycles represents a challenge for the standard equilibrium models of real business cycle. These models successfully explain most first and second moments of the actual time series, but cannot replicate non-linear...
