Title: Selection and the Roy Model in the Neolithic Transition
Abstract: We analyze the evolution of the distribution of genotypes in European populations over the past 14,000 years. In our model, evolution is driven by selection operating after a shift in the productivity of agriculture, induced by the post-Younger Dryas climate change, in a Roy model where individuals self-select into one of two sectors, foraging and farming.
The model extends a standard Wright-Fisher model to include two technologies and sexual reproduction. We test the model in two data sets, ancient and modern DNA, matching the observed distributions of genetic variables (allele frequencies and lineages). We show that a shift in the distribution of allele frequencies in a direction favoring higher cognitive ability, occurred when climate warming changed the relative productivity of agriculture and foraging. The general implication we draw is that historical transformations (e.g., climate change and technological change) may affect the distribution of genotype and thus economic equilibria and institutions.
