into what three categories does the government organise purchases
Government purchases are used to buy the goods and services needed to operate the government (such as administrative salaries) and to provide public goods (including national defense, highway construction). These purchases are one of two major categories of government spending, the other is transfer payments. Government purchases are financed by a mix of taxes and borrowing and are categorized by the three levels of government: federal, state, and local governments. These are one of four expenditures on gross domestic product.
