Financial Liberalization and Consumption Volatility in Developing Countries

One of the chief benefits of financial liberalization proposed by theoretical literature is that it should allow countries to better smooth consumption through international risk sharing. Recent empirical evidence does not support this prediction. In developing countries, financial liberalization seems to be associated with an increase in consumption volatility. This paper seeks to rationalize the evidence by linking it to two important features of developing countries. First, domestic financial markets are underdeveloped. We model this by adopting the Kocherlakota (1996) framework of risk sharing subject to limited commitment. Second, access to international markets is not available to all members of society. We show that when risks are idiosyncratic, that is, insurable within the domestic economy, opening up to international markets reduces the amount of risk sharing attained at home and raises the volatility of consumption. When risk is aggregate to the economy, the underdeveloped financial system prevents the pooling of aggregate risk across agents for the purposes of insurance in the international markets. Thus, while the volatility of consumption coming from aggregate risk decreases with financial liberalization, it does so by much less than would be predicted by a representative agent model
