The Economic Effects of Spending on
Homeland Security
Brian W. Cashell
Specialist in Quantitative Economics

Summary

As a result of the terrorist attacks of September 11 the cost of domestic security has
risen. The only straightforward way to measure the cost of security is to add up the
expenditures for labor and capital that are devoted to the provision of security. In the
case of air travel, security services paid for by the airlines are an intermediate good; that
is, they are an input to the production of air travel rather than output, and are not
counted separately in gross domestic product (GDP). The money spent on security is
a cost of production and so would be reflected mainly in the price index for air travel,
and in overall price indexes to the extent that air travel contributes to total production.
Because of the increase in labor and capital required to produce a safe trip, the
productivity of airlines would also suffer a one-time decline. The same is true for
security expenditures by any firm engaged in the production of other goods and services.
In contrast, when the government pays for security services, it is as a final consumer and
those expenditures are counted explicitly as part of GDP. Any increase in those
expenditures will thus appear as both nominal and real contributions to GDP. The only
enduring effect will be a shift in the share of employment and of expenditures devoted
to security. Relative to the size of the overall economy, these costs are likely to be fairly
small. This report will not be updated.
One direct result of the terrorist attacks of September 11 is that the cost of domestic
security has risen. That increased cost is likely to be in the form of increased outlays on
the military, as well as increases in spending for domestic law enforcement, public safety,
and private security services. Some industries, such as the airlines, will be more affected
than others but there will be nationwide effects because domestic security is a public good
and much of the increased cost will likely be borne by taxpayers.
In light of the current international political environment, it seems likely that many
of the factors motivating the demand for increased domestic security will persist for some
time. Given that there is going to be a sudden and substantial increase in spending on
public safety and security what, if any, are the macroeconomic consequences likely to be?
