Revisiting the empirical evidence on firms' money demand

In this paper we estimate the demand for liquidity by US non-financial firms using the COMPUSTAT database. In contrast to the previous literature, we consider firm-specific effects, such as cost-of-capital and wages. From the balanced and unbalanced panel estimations we infer that there are economies of scale in money demand by US business firms because estimated sales elasticities are smaller than unity. In particular, they are lower than in previous empirical studies, suggesting that economies of scale in the demand for money are even bigger than formerly thought. In addition, it emerges that labor is not a substitute for money. (C) 2006 Elsevier Inc. All rights reserved.
