We provide a nonlinear characterization of the macroeconomic impact of microeconomic TFP shocks in terms of reduced-form non-parametric elasticities for efficient economies.
In an efficient economy, the macro impact of a shock to industry i depends on i ’s sales as a share of aggregate output, up to a first-order of GDP. Hulten’s theorem (Appendix B) motivates the use of sales rather than value added. innovations by Walmart, the difficulties of a Japanese bank, new exports by Boeing, and a strike at General Motors.3 Since modern economies are dominated by large firms, idiosyncratic shocks to these firms can lead to nontrivial aggregate shocks. Hulten’s Theorem (1978) Take an efficient economy with N goods produced by N sectors subject to Hicks-neutral shocks A i. Hulten’s Theorem: ∂ logC ∂ logAi = p iy PC i.e at the first order: logC ≈ N ∑ i=1 p iy i PC logA i ⇒ The effect of shocks on C is summarized by the sales share only! The “Diversification Argument” (Lucas, 1977): Although Hulten’s theorem is most prominent for its use in growth accounting, where it is employed to measure movements in the economy’s production possibility frontier, it is also the benchmark result in the resurgent literature on the macroeconomic impact of microeconomic shocks in mutisector models and models with production networks.2 In this sense, we extend the foundational theorem of Hulten (1978) beyond first-order terms. Key features ignored by first-order approximations that play a crucial role are: structural elasticities of substitution, network linkages, structural returns to scale, and the extent of factor reallocation.

Hulten’s theorem is a cornerstone of productivity and growth accounting: it shows how to construct aggregate TFP growth from microeconomic TFP growth, and provides structurally-interpretable decompositions of changes of national or sectoral aggregates into the changes of their disaggregated component industries or firms. It also provides the
In this sense, we extend the foundational theorem of Hulten (1978) beyond first-order terms to capture nonlinearities.

In this sense, the paper extends the foundational theorem of Hulten (1978) beyond first-order terms to capture nonlinearities. Key features ignored by first-order approximations that play a crucial role are: structural elasticities of substitution, network linkages, structural returns to scale, and the degree to which factors can be reallocated. In this sense, we extend the foundational theorem of Hulten (1978) beyond the first order to capture nonlinearities. Key features ignored by first-order approximations that play a crucial role are: structural microeconomic elasticities of substitution, network linkages, structural microeconomic returns to scale, and the extent of factor reallocation. Hulten’s theorem provides an inaccurate approximation: unit elasticity (Cobb-Douglas) is a bad assumption for oil?

innovations by Walmart, the difficulties of a Japanese bank, new exports by Boeing, and a strike at General Motors.3 Since modern economies are dominated by large firms, idiosyncratic shocks to these firms can lead to nontrivial aggregate shocks. Theorem 2 resembles Hulten’s theorem, suggesting that the Gabaix (2011) result can be extended in the following manner: idiosyncratic shocks to firm-level markups can result in first-order labor wedge movement as long as the firm size distribution is fat-tailed.
