Public sector and human capital: on the mechanics of economic development

Abstract

AbstractThis paper proposes a theory about the allocation of human capital along the development process that helps to understand the controversial impact of this variable in growth regressions. We build a model in which human capital is allocated to three activities: production, tax collection (bureaucracy), and public education. At the first stage of development, countries have low effective tax rates because tax collection requires human capital, which is scarce. As countries accumulate human capital throughout the transition, the effective tax rate rises, diverting human capital from production to bureaucracy and public education. Consequently, at this stage, human capital has a weak impact on production, even when the human capital allocation is efficient. Furthermore, disparities in institutional quality may diminish the correlation between human capital and GDP.
