Human capital,innovation, and growth

This paper explores the interaction between human capital and innovation in the process of economic growth. Using a model of endogenous growth, we focus on how taxes and other policy instruments affect the incentives to invest in human capital. In contrast to many other growth models we find that the taxation of human capital has a substantial negative effect on its accumulation. This in turn reduces innovation and, consequently, the income growth rate. More surprisingly, other policies that are intended to stimulate growth may have opposing effects on innovation and the accumulation of human capital. For example, while subsidies to research and to intermediate inputs do have positive effects on innovation and growth, they lead to a lower stock of human capital, in the empirically relevant case when the elasticity of intertemporal substitution in consumption is low.     

The settlers’ fortunes: Comparing tax censuses in the Cape Colony and early American republic

Europeans at the end of the eighteenth century had settled across the globe, from North and South America to Australia to the southern tip of Africa. While theories of institutional persistence explain the ‘reversal of fortunes’ between settled and unsettled regions, few studies consider the large differences in early living standards between settler societies. This paper uses newly transcribed household-level tax censuses from the Dutch and British Cape Colony and the United States shortly after independence to show comparative levels of income and wealth over four decades both between the two regions and within them. Cape farmers were, on average, more affluent than their American counterparts. While crop output and livestock were more unequally distributed at the Cape, ownership of enslaved people in America was more unequal. There was little indication of an imminent reversal of fortunes.
