We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues.

This paper provides evidence and an explanation for an empirical regularity in the income velocity of money. Based on a cross country comparison in the post World War II period of 84 countries arrayed from very low to very high per capita income, velocity displays a U shaped pattern. This...
