In this paper, the authors present estimates of Tobin's Q for a panel of Spanish firms over the period 1983-87 and test the Q theory of investment. The results are threefold. First, Q is significant in the investment equation but a variable proxying for liquidity constraints is also significant. Second, once those variables are included, sales are not significant. Third, the adjustment costs implied by the authors' estimated parameter are lower than those found in international empirical literature. Copyright 1994 by Blackwell Publishing Ltd
