Abstract

The authors use Morocco's national survey of living standards to measure the short-term welfare impacts of prior estimates of the price changes attributed to various trade policy reforms for cereals-the country's main food staple. They find small impacts on mean consumption and inequality in the aggregate. There are both gainers and losers and (contrary to past claims) the rural poor are worse off on average after trade policy reforms. The authors decompose the aggregate impact on inequality into a"vertical"component (between people at different pre-reform welfare levels) and a"horizontal"component (between people at the same pre-reform welfare level). There is a large horizontal component which dominates the vertical impact of full de-protection. The diverse impacts reflect a degree of observable heterogeneity in consumption behavior and income sources, with implications for social protection policies.
