In its first 100 days, the second Trump administration has been anything but usual by presidential standards. From trade wars to an assault on the federal bureaucracy, President Donald Trump and his team have swiftly reshaped the landscape of government action. Amid the torrent of daily news, some critical policy discussions have been swiftly overlooked.
The commonly known GDP statistic is a simple sum: consumption spending, investment spending, government spending, and net exports (which is spending by foreigners). Government spending in this equation captures government activity such as the hiring of people to work in a new government office or the purchase of uniforms for soldiers.
This somewhat clashes with the formal definition of GDP: the market value of final goods and services. This reveals a conceptual problem as many government goods and services, such as military equipment and bureaucratic administration, aren’t sold in competitive markets. Without genuine market prices, their value is approximated by government spending costs. But the cost says nothing about “value.” After all, the government could hire a million people to dig holes and fill them back up. No value is created but costs are incurred.
This is because military expenditures on weapons and war materials do not directly translate into better material living standards for civilians. Defense spending should be excluded from GDP when assessing living standards because military goods—like tanks, bombs, and bullets—do not directly contribute to civilian welfare. They are not consumed by households, nor do they improve the quality of everyday life. Including them inflates measures of prosperity in ways that misrepresent how ordinary people are actually doing. Moreover, a great deal of government expenditures during wars represent coerced production (e.g., drafts, requisitions, seizures, nationalizations), which makes it harder to evaluate the value to civilians. Finally, during conflicts, governments impose price controls, which hide the true extent of inflation.
Removing the effect of price controls and defense spending, what we dub the Defense-Adjusted National Accounts, provides a clearer picture of civilian living standards uninflated by defense expenditures and artificially suppressed wartime prices.
Of course, these corrections reduce the level of the GDP statistic. But that is not all it does. The corrections produce a new series that alters our understanding of U.S. economic history during various periods. The most obvious, and previously covered by Higgs, is during World War II. The official GDP statistics show an economy growing rapidly, which led many to consider the war effort as key to finally ending the Great Depression. Our corrections, and Higgs’s before ours, clearly show that the economy was declining. That is, for the average consumer, things in the United States were getting worse, not better, during the war.
Finally, pairing our corrected GDP with historical income distribution (i.e., inequality) data reshapes the narrative of the “Great Leveling” during the mid-20th century and particularly during wartime years. The leveling, traditionally celebrated as a period of diminishing inequality, actually coincided with declining living standards for everyone—even the wealthy.
As policymakers grapple with budget priorities, military spending, and public perceptions of economic health, a more accurate measurement of living standards is essential. Adjusting GDP to focus explicitly on private-sector prosperity clarifies whether government actions genuinely contribute to citizen well-being or merely inflate an imperfect statistical measure.
We don’t advocate replacing standard GDP as it captures an approximation of the true statement that not all government expenditures are without value. However, adopting a Defense-Adjusted National Accounts measure can help provide another approximation of a true statement: that wars do not improve living standards. These two approximations together help provide a smaller window for uncertainty. This can help bridge the gap between official economic data and the perceptions of the American public.
