Theories of economic growth hypothesize that the transition from pre-industrial stagnation to sustained growth is associated with a post-Malthusian phase in which technological progress raises income and spurs population growth while offsetting diminishing returns to labour. Evidence suggests...

The price of natural gas has risen significantly since the summer of 2021. Higher heating costs may put downward pressure on homes heated with gas. Seen in isolation, the average price drop will be DKK 73,000 for a house with gas, if the gas price develops in line with the expectations of...

Transitioning to a low-carbon economy implies both risks and opportunities in the Danish housing sector, which accounts for one fourth of Denmark's CO2 emissions. We study the heterogeneous impacts on house prices of rising energy prices and energy renovations by combining micro-level data on...

The majority of energy renovations of houses cost more than they increase the sales price. This holds particularly in the metropolitan area and Aarhus, but also in a number of rural areas. Renovations that increase the sales price more than the renovation costs reduce CO2 emissions only...

This research presents the first evidence that moderate fecundity had maximized long-run reproductive success in the human population. Using a reconstructed genealogy for nearly half a million individuals in Quebec during the 1608-1800 period, we find that while a high fecundity was associated...

This research advances the hypothesis and establishes empirically that interpersonal population diversity, rather than fractionalization or polarization across ethnic groups, has been pivotal to the emergence, prevalence, recurrence, and severity of intrasocietal conflicts. Exploiting an...

Exploiting a novel geo-referenced data set of population diversity across ethnic groups, this research advances the hypothesis and empirically establishes that variation in population diversity across human societies, as determined in the course of the exodus of human from Africa tens of...
