Liquidity Constraints and Business Cycles in Developing Economies

Open economy extensions of real business cycle models, even if generally successful, have met some difficulties replicating a few important stylized facts. In particular, these models tend to predict excessive consumption smoothing and consumption correlations across countries. The observed negative correlation between the trade balance and output in developing countries, the variability of the trade balance and its correlation with the terms of trade have also proven difficult to reproduce. This paper considers how introduction of incomplete markets in the form of liquidity constraints can alleviate these problems. This analysis suggests that adding liquidity constraints helps predict the variability of consumption relative to output. It also improves our estimate of the correlation between the trade balance and output. The model correctly replicates the small positive correlation between the terms of trade and the trade balance. However, it slightly underpredicts the variability of the trade balance when 50% of the consumers are assumed to be liquidity constrained.Journal of Economic LiteratureClassification Numbers: E13, E32, E44.
