This type of policy is usually related to the concept of fiscal deficit. As the amount of public spending is greater than the main amount of taxes collected, the budget deficit increases. In other words, more money is spent on public services than on taxes. The government may resort to an increase in the public deficit, when seeking to increase aggregate demand
The increase in aggregate demand would consist of increases in production with the rise in the amount of public expenditure. A decrease in unemployment is pursued thanks to reductions in the most common taxes, and therefore other results are also achieved such as a greater consumption of goods and services and an increase in terms of investment by companies.
