Commodity Price Shocks and Child Outcomes: The 1990 Cocoa Crisis in Côte d’Ivoire

We look at the drastic cut of the administered cocoa producer price in 1990 Côte d’Ivoire and study to which extent cocoa producers’ children suffered from this severe aggregate shock in terms of school enrollment, labor, height stature, and morbidity. Using precrisis (1985–88) and postcrisis (1993) data, we propose a difference-in-difference strategy to identify the causal effect of the cocoa shock on child outcomes, whereby we compare children of cocoa-producing households and children of other farmers living in the same district or the same village. This causal effect is shown to be rather strong for the four child outcomes we examine. Hence human capital investments are definitely procyclical in this context. We also provide evidence of gender bias against young girls with respect to education and health care. We finally argue that the difference-in-difference variations can be interpreted as private income effects, likely to derive from tight liquidity constraints.

Borders That Divide: Education and Religion in Ghana and Togo Since Colonial Times

The partition of German Togoland after World War I provides a natural experiment to test the impact of British and French colonization. Using data of recruits to the Ghanaian colonial army 1908–1955, we find that literacy and religious affiliation diverge at the border between the parts of Togoland under British and French control as early as in the 1920s. We partly attribute this to policies towards missionary schools. The divergence is only visible in the South where educational and evangelization efforts were strong. Contemporary survey data show that border effects that began in colonial times still persist today.

Development, a Question of Opportunity? A Critique of the 2006 World Development Report: Equity and Development

The World Banks World Development Report 2006 addresses equity and development, defining equity as respect for equal opportunities combined with the avoidance of absolute deprivation. Equity has up to now remained a marginal issue in development economics. This detailed analysis endeavours to place the subject within the context of the evolution of World Bank thinking and policies. The wealth of the concept is illustrated, the downside being the difficulty in defining it accurately. We also emphasise the gap between the prospects opened up by such an enlargement of development goals and the reports policy recommendations, which are generally merely an extension of the World Banks traditional analyses.
