This paper uses a comparison of a contemporary public finance textbook
with one written in the 1940s as a vehicle for assessing the changes
in the field since the beginning of the National Tax Journal 50 years
ago. The comparison indicates that there have been major changes in th
e field. From a methodological point of view, the most important chang
e is the embrace of microeconomic theory as the framework for analyzin
g both positive and normative issues. In addition, the incorporation o
f econometrics has dramatically affected the field. With respect to to
pical coverage, research in public finance has changed along with the
items on the public policy agenda, and the results of this new researc
h have made their way into contemporary textbooks. But there is contin
uity as well as change: some topics and their treatments have metamorp
hosed very little in the last half-century.
