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...

This paper presents a framework to understand and measure the effects of political borders on economic growth and per capita income levels. We present a model providing a theoretical foundation to estimate empirically the effects of political borders on growth. In our model, political...
