- Resumo
- This paper presents a Sraffian criticism of Kenneth Arrow's defence of the empirical relevance of neoclassica! general equilibrium theory. The neoclassical explanation would only make empirical sense if market clearing really happens in the markets for factors of production. This in turn depends on two things: (a) nominal and real "flexibility" of factor prices; and (b) on the (direct and indirect) substitution effects being the dominant effect of factor price changes. However: 1. nominal factor price flexibility is both empirically implausible and anyway tends to be destabilizing (and cause a lack of real flexibility) 2. Sraffa's capital critique shows that in any case the substitution effect may break down completely in the real-world case of heterogeneous capital. An alternative (and more consistent) Sraffa-based explanation of the facts is also briefly sketched.
