Beyond Q: Investment Without Asset Prices

Abstract: 
Empirical corporate finance studies often rely on measures of Tobin’s Q to control for “fundamental” determinants of investment. However, Tobin’s Q is a good summary of investment behavior only under very stringent conditions and it is far better to instead use the underlying state variables directly. In this paper we show that under very general assumptions about the nature of technology and markets, these state variables are easily measurable and greatly improve the empirical fit of investment models. Moreover even a general first or second order polynomial that does not rely on additional details about the nature of the investment problem provides a better overall fit and accounts for a larger fraction of the total variation in corporate investment than standard Q measures.
