This article suggests a simple and straightforward explanation for gov
ernment growth based on the length of time that Congress meets in sess
ion. The basic hypothesis is that the more time spent in session, the
longer and/or more complex the number of bills enacted into law. Becau
se each bill enacted is likely to entail some spending clauses, the bi
lls enacted in longer sessions are likely to involve larger government
spending than those passed in shorter sessions. Using data for both h
ouses of Congress for the period 1947-1982, this article provides evid
ence in support of the hypothesis that government growth can be partia
lly explained by the length of time that Congress takes in session.
