IN normal recessions, however disruptive they are to businesses and jobs, things turn around predictably. The current global recession is far from normal.

Usually, to fight a recession, the central bank lowers interest rates, which results in increased demand and output. People resume buying durable goods such as appliances and cars. Firms start delayed investment projects. Often, an exchange rate depreciation gives a boost to exports by making them cheaper. The lower-than-normal growth during the recession gives way to higher-than-normal growth for some time, until the economy has returned to its normal growth path.
