In a situation of economic recession, where unemployment is rising and companies are closing, the government can use an expansionary fiscal policy to stimulate the economy. This can be done by increasing government spending and reducing taxes on productive activity. The government is a powerful consumer and as it increases its spending, it pours money into the economy and warms the market. In addition, by reducing taxes, the government encourages the productive sector to increase production and contract. Thus the economy can grow back into a virtuous cycle.
