What should be the West's top priority for climate-change policy? This article is a revised and updated version of my talk to the Potsdam Global Sustainability Symposium (which drafted the Potsdam Declaration presented to the 2007 UN Climate Change Conference in Bali).

Vehicle taxation based on CO2 emissions is increasingly being adopted worldwide in order to shift consumer purchases to low-carbon cars, yet little is known about the effectiveness and overall economic impact of these schemes. We focus on feebate schemes, which impose a fee on high-carbon...

Do international trade and finance flow together? In theory, trade and finance can be substitutes or complements, so the matter must be resolved empirically. We study trade and financial flows from the United Kingdom from 1870 to 1913 and the United States in the interwar years. Trade and...

Conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity, especially international trade. Yet nothing is known empirically about these effects in large samples. We study the effects of war on bilateral trade for almost all...

Empirical research on the gravity model of international trade in the wake of Rose (2000) affirms that currency union formation doubles or triples trade. Currency unions could, however, also be established precisely because trade among their members was already high. In OLS estimation, this...

Does democracy encourage free trade? It depends. Broadening the franchise involves transferring power from non-elected elites to the wider population, most of whom will be workers. The Hecksher-Ohlin-Stolper-Samuelson logic says that democratization should lead to more liberal trade policies in...

For two decades, the consensus explanation of the British Industrial Revolution has placed technological change and the supply side at center stage, affording little or no role for demand or overseas trade. Recently, alternative explanations have placed an emphasis on the importance of trade...

Many previous studies of the role of trade during the British Industrial Revolution have found little or no role for trade in explaining British living standards or growth rates. We construct a three-region model of the world in which Britain trades with North America and the rest of the world,...

In this paper, we provide aggregate trends in China’s trade performance from the 1840s to the present. Based on historical benchmarks, we argue that China’s recent gains are not exclusively due to the reforms since 1978. Rather, foreign economic activity can be understood by developments...

Existing theories of pre-emptive war typically predict that the leading country may choose to launch a war on a follower who is catching up, since the follower cannot credibly commit to not use their increased power in the future. But it was Japan who launched a war against the West in 1941, not...
