In most macroeconomic models, austerity policies which reduce government spending lead to increased unemployment in the short term. These reductions in employment usually occur directly in the public sector and indirectly in the private sector. Where austerity policies are enacted using tax increases, these can reduce consumption by cutting household disposable income. This also tends to reduce employment in the short term. Reduced government spending can reduce GDP growth in the short term as government expenditure is itself a component of GDP. In the longer term, reduced government spending can reduce GDP growth if, for example, cuts to education spending leave a country's workforce less able to do high-skilled jobs or if cuts to infrastructure investment impose greater costs on business than they saved through lower taxes. In both cases, if reduced government spending leads to reduced GDP growth, austerity may lead to a higher debt-to-GDP ratio than the alternative of the government running a higher budget deficit. In the aftermath of the Great Recession, for instance, austerity measures in many European countries were followed by rising unemployment and slower GDP growth. The result was increased debt-to-GDP ratios despite reductions in budget deficits.
