Sachs and Kotlikoff, “Smart Machines and Long-Term Misery” (2012-12) articulates M01. 'Smart machines' enter the model as machinery whose efficiency parameter u rises, a factor-augmenting technical change in a nested CES production function with unskilled and skilled labour. Copy claim link

Date 2012-12 · publication Wording attested 2013-01. The cover lists "December 2012, January 2013"; the retrieved PDF may be the January 2013 revision, so its wording is attested from 2013-01 only. Role Articulation Register (kind of text) Nonfiction Tier Tier 1. NBER working paper (core venue); both authors economists. Conditions Machines and unskilled labour combine in a CES intermediate; the intermediate combines with skilled labour; u is machine efficiency. Scope and limits NBER Working Paper 18629, dated December 2012, revised January 2013; a highly stylised two-period OLG model, not an empirical estimate or forecast. The rhetoric stresses 'smart machines' with 'microprocessor brains' (pdf p. 3), but the formal analysis has no separate category for machine cognition; a reader should weigh rhetoric and model separately.
