On the measurement of investment types: Heterogeneity in corporate tax elasticities
This paper highlights the importance of different investment motives and to what extend they affect the responsiveness to
corporate taxation. In particular, we discuss how to classify investment as non-related, horizontal, vertical and complex
types using a combination of both firm-specific (ownership) information and sector-specific information from input-output
tables. Hereby, we point out to what extent the resulting classification depends on assumptions made by the researcher. Following
this, we examine the effects of host-country corporate taxation on the volume of investment within related firms (i.e., the
intensive margin). We are able to quantitatively replicate the average result in the empirical literature with an overall
tax semi-elasticity of approximately –1.5. Taking into account firm-heterogeneity we find that non-related investments react
stronger to corporate taxation whereas horizontal investments are less responsive, though, significant negative tax semi-elasticities
turn out for the subset of manufacturing industries where horizontal investment is much more prevalent. As the strict categorical
classification still yields ambiguous results for both vertical and complex investments we extend the methodology by defining
shares of investment and make the point that, by and large, stronger business motives reduce the tax responsiveness of investment.
