This research explores the biocultural origins of human capital formation. It presents the first evidence that moderate fecundity and thus predisposition towards investment in child quality was conducive for long-run reproductive success within the human species. Using an extensive genealogical...

We explore the relationships between subjective well-being and income, as seen across individuals within a given country, between countries in a given year, and as a country grows through time. We show that richer individuals in a given country are more satisfied with their lives than are poorer...

In recent decades economists have turned their attention to data that asks people how happy or satisfied they are with their lives. Much of the early research concluded that the role of income in determining well-being was limited, and that only income relative to others was related to...

The "Easterlin paradox" suggests that there is no link between a society’s economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear positive...

This Paper hypothesizes that the demise of the 19th century's European class structure reflects a deliberate transformation of society orchestrated by the Capitalists. Contrary to conventional wisdom, it argues that the demise of this class structure has been in part an outcome of a cooperative...

This research contributes to the understanding of human genetic diversity within a society as a significant determinant of its economic development. The hypothesis advanced and empirically examined in this paper suggests that there are socioeconomic trade-offs associated with genetic diversity...

This research argues that the rapid expansion of international trade in the second phase of the industrial revolution has played a major role in the timing of demographic transitions across countries and has thereby been a significant determinant of the distribution of world population and a...

This research argues that the differential effect of international trade on the demand for human capital across countries has been a major determinant of the distribution of income and population across the globe. In developed countries the gains from trade have been directed towards investment...

This research argues that international trade has played a significant role in the timing of demographic transitions across countries and has thereby been a major determinant of the distribution of world population and a prime cause of sustained differences in population growth and income levels...

This paper empirically tests the predictions of the Malthusian theory with respect to both population dynamics and income per capita stagnation in the pre-Industrial Revolution era. The theory suggests that improvements in technology during this period generated only temporary gains in income...
