How To Create A Depression

Cambridge - European political leaders may be about to agree to a fiscal plan which, if implemented, could push Europe into a major depression. To understand why, it is useful to compare how European countries responded to downturns in demand before and after they adopted the euro.

Consider how France, for example, would have responded in the 1990’s to a substantial decline in demand for its exports. If there had been no government response, production and employment would have fallen. To prevent this, the Banque de France would have lowered interest rates. In addition, the fall in incomes would have automatically reduced tax revenue and increased various transfer payments. The government might have supplemented these “automatic stabilizers” with new spending or by lowering tax rates, further increasing the fiscal deficit.

In addition, the fall in export demand would have automatically caused the franc’s value to decline relative to other currencies, with lower interest rates producing a further decline. This combination of monetary, fiscal, and exchange-rate changes would have stimulated production and employment, preventing a significant rise in unemployment.

But when France adopted the euro, two of these channels of response were closed off. The franc could no longer decline relative to other eurozone currencies. The interest rate in France – and in all other eurozone countries – is now determined by the European Central Bank, based on demand conditions within the monetary union as a whole. So the only countercyclical policy available to France is fiscal: lower tax revenue and higher spending.
