Inflation reduces the ability of economic agents to operate efficientl
y in a private enterprise system. To test and evaluate the strength of
this effect, inflation variables are included in an empirical growth
relationship for the U.S. private business sector. Both the rate of in
flation and the change in the rate of inflation have significant negat
ive effects on output growth. Two by-products of the analysis are the
following. First, some but not all of the apparent post-1973 decline i
n productivity growth can be explained by an increase in the size of t
he services producing sector relative to the goods producing sector. S
econd, the rate of growth of private sector output is independent of t
he rate of growth of government non-military capital stock.
