Contributor(s): Philip Coggan | The world is drowning in debt. Greece is on the verge of default. In Britain, the coalition government is pushing through an austerity programme in the face of economic weakness. The US government almost shut down in August because of a dispute over the size of government debt. Our latest crisis may seem to have started in 2007, with the collapse of the American housing market. But as Philip Coggan shows in this new book, Paper Promises: Money, Debt and the new World Order which he will talk about in this lecture, the crisis is part of an age-old battle between creditors and borrowers. And that battle has been fought over the nature of money. Creditors always want sound money to ensure that they are paid back in full; borrowers want easy money to reduce the burden of repaying their debts. Money was once linked to gold, a commodity in limited supply; now central banks can create it with the click of a computer mouse. Time and again, this cycle has resulted in financial and economic crises. In the 1930s, countries abandoned the gold standard in the face of the Great Depression. In the 1970s, they abandoned the system of fixed exchange rates and ushered in a period of paper money. The results have been a long series of asset bubbles, from dotcom stocks to housing, and the elevation of the financial sector to economic dominance. The current crisis not only pits creditors against debtors, but taxpayers against public sector workers, young against old and the western world against Asia. As in the 1930s and 1970s, a new monetary system will emerge; the rules for which will likely be set by the world's rising economic power, China.
