On Accounting "Capital" in Horizontal Innovation Models
AbstractI identify and correct some logical problems of the 1990 Romer model of horizontal innovation. The model's setting where all the produced inputs are durable is inconsistent with the proposed Dixit-Stiglitz production function; also, Romer's "accounting measure of capital" (and its variants in the literature) is not a theoretically proper measure on which the rate of interest is to be calculated. The correction is straightforward. However, a more fundamental issue is at stake: the structure of horizontal innovation models necessitates consideration of the problem of value, but the current literature deliberately assumes it away, generating internal inconsistency of various forms.
