Height is the result of a complex process of growth that begins at birth and reaches the end in early adulthood. This paper studies the determinants of height from birth to maturity. A height production function is specified whose structure allows height to be the result of the accumulation of...

We play a one-shot public good game in rural India between farmers connected by an exogenous star network. Contributions by the centre of the star reach more players and have a larger impact on aggregate payoffs than contributions by the spoke players. Yet, we find that the centre player...

Standard models often predict that people should either demand to save or demand to borrow, but not both. We hypothesise instead that saving and borrowing among microfinance clients are substitutes, satisfying the same underlying demand: for a regular schedule of deposits and a lump-sum...

We gave US$1,000 cash prizes to winners of a business ideas competition in Africa. The competition, entitled ‘Aspire’, is intended to attract young individuals aspiring to become entrepreneurs. Participants were ranked by panels of judges composed of established entrepreneurs. Each panel...

We analyse intertemporal poverty in two important dimensions income and nutrition in less developed northwest China during 2000-2004. A generalised recursive selection model is proposed which enables simultaneous estimation of the causes of intertemporal poverty within and between dimensions....

This paper looks at the link between housing conditions and household income and labour market participation in South Africa. I use four waves of panel data from 2002-2009 on households that were originally living in informal dwellings. I find that those households that received free government...

Do high costs of search affect the labour market outcomes of young job seekers living far away from the centre of cities? I randomly assign temporary and non-fungible transport subsidies to unemployed youth living in spatially dislocated areas of Addis Ababa, Ethiopia. Lowering transport costs...

We present a theoretical model of moral hazard and adverse selection in an imperfectly competitive loans market that is suitable for application to Africa. The model allows for variation in both the level of contract enforcement (depending on the quality of governance) and the degree of market...
