The paper proposes a technique to jointly tests for groupings of unknown size in the cross sectional dimension of a panel and estimates the parameters of each group, and applies it to identifying convergence clubs in income per-capita. The approach uses the predictive density of the data,...

Since the highest income groups have tremendous influence over economic policy by virtue of money, position, and connection, it is important to identify the interest of these groups with regard to economic conditions. Recently, annual time series data on the shares of the very highest income...

Trade policy reforms in recent decades have sharply reduced the distortions that wereharming agriculture in developing countries, yet global trade in farm products continues to befar more distorted than trade in nonfarm goods. Those distortions reduce some forms ofpoverty and inequality but...

We test the hypotheses that subsidies on hybrid seed change maize production, total household income, the severity of poverty, and relative deprivation among smallholder maize growers in Zambia. The analysis contributes to the literature by measuring the quantitative effects of seed (as compared...

Argues that it is unrealistic to expect the net benefit of economic globalization to be represented by a single monetary figure because its consequences are diverse and several of its consequences are uncertain. The benefits of economic globalization are accessed in terms of its possible impact...

A parsimonious demand modeling approach has been developed for the annual USDA-ERS International Food Security Assessment. The approach incorporates price effects, food quality variation across income deciles, and consistent aggregation over income deciles and food qualities. The approach is...
