## An intellectual history of IPE

In his Introduction to International Political Economy: An Intellectual History, Cohen traces the genesis and development of the rapidly growing field of international political economy. He documents the work of the key pioneers of the discipline: Robert W. Cox, Robert Gilpin, Peter Katzenstein, Robert Keohane, Charles Kindleberger, Stephen Krasner and Susan Strange and he charts the development of IPE from these foundations to the present.
At the heart of the book is a depiction of IPE being divided into American and British camps. The Americans are being positivists and attempting to develop intermediate level theories that are supported by some form of quantitative evidence. The work asserts that British IPE is more "interpretivist" and looks for "grand theories" and that they use very different standards of empirical work. Cohen sees benefits in both approaches.
This characterisation of IPE has been hotly debated. One forum for this was the "2008 Warwick RIPE Debate: ‘American’ versus ‘British’ IPE" where Cohen, Mark Blyth, Richard Higgott, and Matthew Watson followed up on the recent exchange in RIPE. Higgott and Watson in particular, are querying the appropriateness of Cohen's categories.

## Cohen's life work

Benjamin Cohen's life work is the political analysis of currencies. In Geography and the Future of money, Cohen began with what Susan Strange had begun: the currency pyramid. Cohen's work focused then on the denationalization of the currency or the monetary integration begun by the Economic and Monetary Union of the European Union. The denationalization of the currency was a leaflet by Friedrich Hayek and others: the Pélérin Society and the Bellagio Group that constructed the European Currency Unit and later the euro as a pedestal of monetary federalism or to get the currency out of the hands of politicians. Cohen argues that a currency is in need of a state, developing after the currency pyramid the Westephalian model of money/ The core of this thinking is that the currency is the heart of a state's sovereignty, thus protected from interference from outside and thus a political construct.
In Currency Power Cohen began to analyse the necessary power attributes in designing an international currency and what is benefits are. Surely, the dollar is here the example, but he also gives a clear picture about the euro and the yuan. Other concepts he has designed are the power to deflect and the power to delay. Those benefits states has with issuing an international currency in the realm of international finance: whilst the former is to deflect the adjustment burden on to other, the latter refers to the delay of the adjustment. An adjustment in international finance flows down the hill: creditors have leverage on debtors to design the international outcome. Debtors have to adjust but with an international currency as is the dollar, power is made in international finance.
In Currency Statecraft Cohen develops the thesis that great powers have great currencies. He states the life cycle of top currencies building on history such as the development and decline of the pound, the Deutschmark or the yen (youth, maturity, decline and death). Only the dollar still reigns supreme, the euro is an not unleashed power having failed the ambition of their creators. The yuan is the competitor of the dollar, symbolizing the growing economic power of China. The internationalization of the euro and the yuan had as purpose to diminish the power of the dollar in the international monetary system. The power of the dollar is summarized by Richard Nixon: 'the dollar is our currency but everyone else's problem'. Furthermore, inertia favours the dollar.
