This paper reviews the empirical evidence on the relationship between economic output and various dimensions of air and water quality. Pollution may rise with growth, because an increased scale of economic activity means more emissions, ceteris paribus. Economic growth may be associated with a...

African societies exported more slaves in colder years. Lower temperatures reduced mortality and raised agricultural yields, lowering slave supply costs. Our results help explain African participation in the slave trade, which predicts adverse outcomes today. We use an annual panel of African...

This paper systematically examines the role of fiscal policy, trade and energy taxes on environmental quality in Europe using disaggregated data for 12 European countries over the 1995-2008 period. It uses a methodology that obtains estimates mostly free of time-varying omitted variable biases....

Contestants have to choose whether to initiate a contest or war, or whether to remain peaceful for another period. We find that agents wait and initiate the contest once their rival is sufficiently weak to be an easy target.

Why is there delay in contests? In this Paper we follow and extend the line of reasoning of Carl von Clausewitz to explain delay. For a given contest technology, delay may occur if there is an asymmetry between defense and attack, if the expected change in relative strengths is moderate, and if...

Japanese GDP per capita grew at an annual rate of 0.04 per cent between 725 and 1874, but the growth was episodic, with the increase in per capita income concentrated in three periods, 1150-1280, 1450-1600 and after 1730, interspersed with periods of stable per capita income. There is a...

This paper makes three contributions to the growing literature on culture and economics. Using answers to the World Values Survey for a sample of 79 countries over the 1989-2004 period, we first provide evidence of cultural homogenization between countries. Second, we provide a model of...

This research argues that deep-rooted factors, determined tens of thousands of years ago, had a significant effect on the course of economic development from the dawn of human civilization to the contemporary era. It advances and empirically establishes the hypothesis that, in the course of the...
