Business Fixed Investment and the Structure of Adjustment Costs
Tamer Abdelgawad,Changyong Rhee 서울대학교 경제연구소 1998 Seoul journal of economics Vol.11 No.2
This paper empirically tests an irreversible investment model against the standard convex adjustment cost model using panel data from COMPUSAT. It shows that the reduced form of the optimal irreversible investment decision turns out to be a Tobit model with measurement errors in the dependent variable. Our non-nested test indicates that the evidence for the irreversible investment model is weak: Only 5 firms among our total sample of 56 firms strictly prefer the irreversibility specification.
