The effect on the poor of changes in the price of staple foods is a central issue in debates on development policy. In the short run the rural rich are likely to gain, and the rural poor to lose, from an increase in the relative price of food staples in a food producing economy. However, in the...

There has been much debate about how much poor people in developing countries gain from trade openness, as one aspect of"globalization."The author views the issue through both"macro"and"micro"empirical lenses. The macro lens uses cross-country comparisons and aggregate time series data. The...

In a world with volatile food prices, countries have an incentive to shelter their populations from induced real income shocks. When some agents are net food producers while others are net consumers, there is scope for insurance between the two groups. A domestic social protection scheme would...

To the surprise of many observers, the 2005 International Comparison Program (ICP) found substantially higher purchasing power parity (PPP) rates, relative to market exchange rates, in most developing countries. For example, China’s price level index -- the ratio of its PPP to its exchange...

It is widely assumed that pervasive credit market failures mean that a person's current wealth is critical to whether or not that person can take up opportunities to start a new business. The authors show that inequality in wealth can be either good or bad for the level of entrepreneurship in an...

In theory, it is possible that the persistent poverty that has emerged in many transition economies, is attributable to underlying, non-convexities in the dynamics of household incomes - such that a vulnerable household will never recover from a sufficiently large, but short-lived shock to its...

The widely held view that larger families tend to be poorer in developing countries has influenced research and policies. But the basis for this"stylized fact"is questionable, the authors argue. Widely cited evidence of a strong negative correlation between size and consumption per person is...

This paper discusses the effect that changes in individual incomes have on aggregate undernutrition. Undernutrition depends not only on nutrient intakes but on other factors, including nutrient requirements - which may differ widely amongst people. The author offers an approach to measuring the...

The authors use China's national household surveys for rural and urban areas to measure and explain the welfare impacts of the changes in goods and factor prices attributed to WTO accession. Price changes are estimated separately using a general equilibrium model to capture both direct and...

In a data set for developing, and transition economies, the author finds that private consumption per capita, based on national accounts, deviates on average from mean household income,or expenditure based on national sample surveys. Growth rates also differ systematically, so that the ratio of...
