The takeaway from six years of economic troubles? Keynes was right.

By Anatole Kaletsky

In more extreme cases, such as Italy and Spain, fiscal tightening has plunged them back into deep recession and aggravated financial crises. Meanwhile countries that ignored their deficit problems, as in the United States for most of the post-crisis period, or where governments decided to downplay their fiscal tightening plans, as in Britain this year or Japan in 2013, have generally done better, both in terms of economics and finance. The one major exception has been Germany, where budgetary consolidation has managed to coexist with decent growth, largely because of a boom in machinery exports to Russia and China that is now over, pushing Germany back into the recession its stringent fiscal policy suggested all along.

Recessions generally occur when private business and households decide to spend less than their incomes in order to reduce their debts or increase their savings. If this process of “deleveraging” is happening in the private sector, which it clearly has been, then simple arithmetic shows that economic balance can only be restored if some other sector of the economy spends more than its income – and such excess spending is only possible if that “other sector” is willing to increase its debts. Disregarding the role of exports and imports, which must sum to zero for the world as a whole, the government is the only possible candidate to play the crucial balancing role as the “other sector.” It is therefore a mathematical certainty that governments must increase their borrowing whenever businesses and households decide to boost their savings by spending less than they earn.
