The paper examines determinants of private consumption in a sample of developing countries. The empirical model includes income, a proxy for the cost of consumption, and the exchange rate. Anticipated movements in these determinants are likely to affect planned consumption, while unanticipated changes determine cyclical consumption. Fluctuations in private consumption are mostly cyclical with respect to income and to a lesser extent the exchange rate. Consumption increases with income and decreases in the face of a higher cost. Currency fluctuations have mixed results on private consumption. As for the effects of domestic policies, fiscal policy has a limited and sometimes a negative effect on private consumption. Monetary growth, in contrast, stimulates an increase in private consumption.This evidence supports the calls to decrease the role of government and enhance the role of monetary policy to stimulate private activity in developing countries.
