Looking beyond averages in the trade and poverty debate2004

"There has been much debate about how much poor people in developing countries gain from trade openness, as one aspect of 'globalization.' Ravallion views the issue through both 'macro' and 'micro' empirical lenses. The macro lens uses cross-country comparisons and aggregate time series data. The micro lens uses household-level data combined with structural modeling of the impacts of specific trade reforms. The author presents case studies for China and Morocco. Both the macro and micro approaches cast doubt on some wide generalizations from both sides of the globalization debate. Additionally the micro lens indicates considerable heterogeneity in the welfare impacts of trade openness, with both gainers and losers among the poor. The author identifies a number of covariates of the individual gains. The results point to the importance of combining trade reforms with well-designed social protection policies. This paper--a product of the Poverty Team, Development Research Group--is part of a larger effort in the group to assess the distributional impacts of economywide policies"--World Bank web site.
