The passage of time has long been known to have economic effects, The most
important effect in the arts has heretofore been the so-called "cost diseas
e" whereby productivity in manufacturing and even sen-ice activities outstr
ips those in cultural pursuits, notably the performance arts. Naturally, a
positive income effect on demand would tend to mitigate this supply effect.
This paper posits yet another side ro wage and income increases - the Beck
erian notion that such increases also raise the opportunity cost of time, p
otentially adding to the effect of the "cost disease." The implications of
this effect are discussed in this paper and a preliminary statistical test
for significance is developed and conducted. The results support the econom
ic significance suggested for the aggregate demand for symphony concerts.
