Many of the plant species that are cultivated for food across the world are neglected and underutilized. To assess their diversity in Benin and identify the priority species and establish their research needs, a survey was conducted in 50 villages distributed throughout the country. The study revealed 41 neglected and underutilized crop species (NUCS) among which 19 were identified as of priori...

We study changes in time and money available to families with children from 1971 to 2006. Increases in incomes at the top of the Canadian income distribution since the mid-1990s have taken place without any significant increases in total family hours of paid work. On the other hand, for families in the middle of the income distribution, family income has stagnated, despite the fact that parents...

The paper uses the Lewis model as a framework for examining the labour market progress of two labour-abundant countries, China and South Africa, towards labour shortage and generally rising labour real incomes. In the acuteness of their rural-urban divides, forms of migrant labour, rapid rural-urban migration, and high and rising real wages in the formal sector, the two economies are surprising...

The data show large dispersion in households’ wealth holdings at retirement. In addition, the empirical correlation between household lifetime earnings and retirement wealth is much lower in the data than in many quantitative models. This paper quantifies and analyzes the implications of a life cycle model with intergenerational links (in the form of voluntary bequest motives and intergeneratio...

There are two contradictory answers to the question in the title. The first is the good growth hypothesis: economic growth generates higher incomes, which should make people approve of the government. Hence growth generates stability. The second is the destabilizing growth hypothesis: growth generates complex changes in society, and therefore instability. A part of the instability will be polit...

In recent decades, China has experienced double-digit economic growth rates and rising inequality. This paper implements a new decomposition approach using the China Health and Nutrition Survey (1991-2006) to examine the extent to which changes in level and distribution of incomes and in income mobility are related to health disparities between rich and poor. We find that health disparities in ...

The impact of pollution and abatement policy within a stochastic endogenous growth model is analyzed. Environmental care is provided by the government and financed through income taxation and government bonds. Due to environmental preferences and partial perception of the individual’s impact on pollution, government debt influences equilibrium growth. Hence, there is an additional growth effect...

This paper uses newly collected household survey data from Accra, Ghana, to investigate whether incomes affect acute and chronic health outcomes in settings that can be considered representative for the large and rapidly growing urban centers of sub-Saharan Africa. The Time Use and Health Study in Accra collected information on incomes, current health status, and health care use from 5,484 pers...

This paper examined how the 1996 Personal Responsibility and Work Opportunity Reconciliation Act, which banned Supplemental Security Income to the majority of elderly immigrants, affected their employment, retirement, and family incomes. The policy was found to be associated with a 3.5 percentage point (9.5 percent) increase in the employment and a 3.8 percentage point (7 percent) decrease in t...

This paper examines three possible approaches to pro-poor growth. The first one assumes that the poverty line remains constant in real terms over time. The second perspective examines the case where the poverty line is equal to half the median of the income distribution but assumes that such a poverty line is determined exogenously. Finally the authors also propose a third type of decomposition...
