The impact of school resources on the quality of education in developing countries may depend crucially on whether resources are targeted efficiently. In this paper we use a randomized experiment to analyze the impact of a school grants program in Senegal, which decentralized a portion of the...

An extensive literature uses anthropometric measures, typically heights, to draw inferences about living standards in the past. This literature's influence reaches beyond economic history; the results of historical heights research appear as crucial components in development economics and...

Human development, in combination with technology, yields economic growth which, in turn, is necessary to generate further advances in human development. This paper focuses on the first channel above and finds the relationship significant. Secondly, the paper tries to investigate what affects...
