En este artículo se propone un método numérico para la calibración de un modelode equilibrio general dinámico y estocástico (DSGE). Esencialmente, éste consisteen utilizar un algoritmo híbrido de optimización, primero para encontrar un estadoestacionario del modelo, y luego para...

Despite various payment innovations, today, cash is still heavily used to pay for low-value purchases. This paper develops a simulation model to test whether standard implications of the theory on cash management and payment choices can explain the use of payment instruments by transaction size....

Este documento analiza la eficiencia (técnica, de escala, de costos y asignativa) del sistema bancario colombiano entre 2000-2012, utilizando la metodología DEA (Data Envelopment Analysis). Ésta se basa en funciones de producción individuales de las entidades que componen el sistema,...

Despite foreign reserves´ strategic asset allocation relies mainly on Modern Portfolio Theory (MPT), the unique characteristics of central banks obliges them to articulate and reconcile typical optimization procedures with reserves´ management objectives such as providing confidence regarding...

There is now an impetus to apply dynamic stochastic general equilibrium models to forecasting. But thesemodels typically rely on purpose-built data, for example on tradable and nontradable sector outputs.How then do we know that the model will forecast well, in advance? We develop an early...

The sudden collapse of oil prices poses a challenge to inflation targeting central banks in oil exporting economies. This paper illustrates that challenge and conducts a quantitative assessment of the impact of permanent changes in oil prices in a small and open economy, in which oil represents...

If theory-consistent models can ever hope to forecast well and to be useful for policy, theyhave to relate to data which though rich in information is uncertain, unbalanced and sometimes forecastsfrom external sources about the future path of other variables. One example from many is financial...

In this paper we expanded the closed economy model by Bernanke and Gertler (1999) in order to account for the macroeconomic effects of an asset price bubble in the context of a small open economy model. During the nineties emerging market economies opened their financial accounts to foreign...

The history of economic recessions has shown that every deep downturn has been accompanied by disruptions in the ?financial sector. Paradoxically, up until the ?financial world crisis of 2007-2009, little attention was given to macroeconomic and ?financial interdependence. And, in spite of a...

I build a general equilibrium, Þnancial accelerator model that incorporates an explicit technology for the intermediary sector. A credit multiplier emerges be- cause of a borrowing constraint that is a function of asset prices, internal funds and lending rates. With this Þnancial friction I...
