Determinants of Business Fixed Investment: Evidence from German Firm-Level Data

This paper employs a novel firm-level dataset that combines financial accounts of German firms with data from a business survey to shed new light on the demand for capital. The empirical analysis employs firm-specific indicators in order to explore the effects of sales, the cost of capital and indicators of the business climate, which are used by the ifo Institute to provide a leading indicator for the German economy. The empirical results support a robust significant effect of a firm's cost of capital on the stock of capital with an elasticity not significantly different from - 1. Controlling for sales, a good rather than normal business situation is found to be associated with about 8% higher investment.
