Should Britain join the Euro? : the chancellor's five tests examined

European economic and monetary union is driven by politics, but the economic costs and benefits of Britain's membership can and should be assessed, argues Professor Patrick Minford in this careful and succinct analysis of the cases for and against Britain adopting the Euro. The core argument in favour is the reduction of exchange-rate risk, but because the Euro is a regional currency that has fluctuated considerably against the dollar, exchange-rate variability might not be less under the Euro and could even increase. In any case, financial markets can diversify away such risks. Minford sees substantial costs of membership: increased variability of UK output, employment and prices in response to shocks; damaging harmonisation of tax rates, social support and regulation; and the possibility that British taxpayers will have to meet some of the costs of big projected state pension deficits in Germany, France and Italy. He concludes that EMU, 'as it is constituted and planned would be strongly against British interests to join'.
