In the 1930s and 1940s, when
the modern system of national income and product accounts (NIPA) was being
developed, the scope of national product was a hotly debated issue. No issue
stirred more debate than the question, Should government product be included in
gross product? Simon Kuznets (Nobel laureate in economic sciences, 1971), the
most important American contributor to the development of the accounts, had
major reservations about including all government purchases in national
product. Over the years, others have elaborated on these reasons and adduced
others.
Why should government product
be excluded? First, the government’s activities may be viewed as giving rise to
intermediate, rather than final products, even if the government provides such
valuable services as enforcement of private property rights and settlement of
disputes. Second, because most government services are not sold in markets,
they have no market-determined prices to be used in calculating their total
value to those who benefit from them. Third, because many government services
arise from political, rather than economic motives and institutions, some of
them may have little or no value. Indeed, some commentators—including the
present writer—ultimately went so far as to assert that some government
services have negative value: given a choice, the people victimized by these
“services” would be willing to pay to be rid of them.
When the government attained
massive proportions during World War II, this debate was set aside for the
duration of the war, and the accounts were put into a form that best accommodated
the government’s attempt to plan and control the economy for the primary
purpose of winning the war. This situation of course dictated that the
government’s spending, which grew to constitute almost half of the official GDP
during the peak years of the war, be included in GDP, and the War Production
Board, the Commerce Department, and other government agencies involved in
calculating the NIPA recruited a large corps of clerks, accountants,
economists, and others to carry out the work.
