Dr. Kamerschen et Jh. Park, MARKET-STRUCTURE AND CYCLICAL FLUCTUATIONS IN UNITED-STATES MANUFACTURING - COMMENT, Review of economics and statistics, 75(4), 1993, pp. 732-734
Domowitz, Hubbard, and Peterson (DHP, 1988) estimate industry markups
of price over marginal cost and show the influence of market structure
on cyclical movements in total factor productivity, using a disaggreg
ate panel data set of 284 four-digit, Standard Industrial Classificati
on, industries. In this comment we examine whether DHP really estimate
what they intend to estimate. DHP also claim their ''estimates are no
t as large as those of Hall'' (p. 56). If it is not clear what they es
timate, the comparison is of limited usefulness. Nevertheless, the DHP
study deserves consideration and contemplation by anyone interested i
n industrial economics.
