World food prices have increased dramatically in recent years. We use panel data from 2006 to examine the impact of these increases on the consumption and nutrition of poor households in two Chinese provinces. We find that households in Hunan suffered no nutrition declines. Households in Gansu...

Many developing countries use food price subsidies or price controls to improve the nutrition of the poor. However, subsidizing goods on which households spend a high proportion of their budget can create large wealth effects. Consumers may then substitute towards foods with higher...

This paper provides the first rigorous, empirical evidence of the existence of Giffen behavior, i.e., a situation in which consumers respond to an increase in the price of a good by demanding more of it. We begin by examining several theoretical approaches to the Giffen phenomenon and show that...

Many developing countries use food-price subsidies or controls to improve nutrition. However, subsidizing goods on which households spend a high proportion of their budget can create large wealth effects. Consumers may then substitute toward foods with higher nonnutritional attributes (such as...

Caloric intake and minimum calorie thresholds are widely used in developing countries to assess hunger and nutrition, and to construct poverty lines. However, it is generally recognized that the sufficiency of an individual's caloric intake cannot be determined, due to: a lack of consensus on...

This paper provides the first real-world evidence of Giffen behavior, i.e., upward sloping demand. Subsidizing the prices of dietary staples for extremely poor households in two provinces of China, we find strong evidence of Giffen behavior for rice in Hunan, and weaker evidence for wheat in...

Information and communications technologies (ICTs) have spread rapidly in the developing world. There has been considerable interest in the potential role ICTs, particularly mobile phones, have begun to play in the marketing of agricultural outputs in these countries. In this paper, we discuss...
