This paper analyzes the role of world price shocks, namely fluctuations in the prices of capital, intermediate and primary goods, and the world real interest rate, in the generation and propagation of business cycles in developing countries, using a stochastic dynamic multi-sector model of a...

Inflation is often associated with a loss for the poor in the medium and long run. The cyclical effects are basically unknown. We study this question in a dynamic optimizing sticky price model. Agents are heterogeneous with regard to their age and their productivity. We emphasize three channels...

We prove the existence of monetary equilibrium in a finite horizon economy with production. We also show that if agents expect the monetary authority to significantly decrease the supply of bank money available for short term loans in the future, then the economy will fall into a liquidity trap...

We show diverse beliefs is an important propagation mechanism of fluctuations, money non neutrality and efficacy of monetary policy. Since expectations affect demand, our theory shows economic fluctuations are mostly driven by varying demand not supply shocks. Using a competitive model with...

Since the beginning of the year 2012, foreign currencies exchange rates against the domestic Sudanese currency saw continuous rise. That happened even though there were universal fluctuations for them due to continuous financial crisis. The continuous appreciations of foreign currencies in Sudan...

We study the implications of increased price flexibility on aggregate output volatility in a dynamic stochastic general equilibrium (DSGE) model. First, using a simplified version of the model, we show analytically that the results depend on the shocks driving the economy and the systematic...

Este trabajo pretende determinar qué conjunto de rigideces nominales y reales se debe incluir en un modelo DSGE para replicar la dinámica de las variables agregadas de la economía colombiana. Con este fin, se estiman varios modelos DSGE con distintas combinaciones de rigideces nominales y...
