• Things to notice: 1. Price of a good depends on its TFP and on the price of its inputs. 2. Prices propagate downstream. • Hulten's theorem: d log Y d log zi. 22 Apr 2020 Hulten's theorem states that in an efficient economy, the Domar weights are sufficient statistics for the first-order effects of sectoral productivities Key-words: singular operators, time derivative, hypervirial theorem, Ehrenfest theorem, Coulomb and virial theorem for Coulomb and oscillator potentials was considered and corrections to the Kramers' sum The Hulten potential: In this sense, we extend the foundational theorem of Hulten (1978) beyond the first order to capture nonlinearities.
Abstract: We provide a nonlinear characterization of the macroeconomic impact of microeconomic TFP shocks in terms of reduced-form non-parametric elasticities for efficient economies. 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 thebenchmark result in the resurgent literature on the macroeconomic impact of microeconomic shocks in mutisector models and models with production networks. 2 HULTHÉNS, ALLT UNDER ETT TAK - FÖRSÄLJNING Hulthéns erbjuder försäljning av lastväxlarflak, lastväxlarramar, liftdumpercontainer, kapell, återvinningshus, miljöskåp, miljöcontainer, glödlampsbehållare och specialanpassade produkter.

Although Hulten’s theorem is most prominent for its use in growth accounting, where it is used 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 multisector models and models with production networks, where it is used to make counterfactual predictions.

Hulten Theorem IHulten Theorem 1 Introduction The foundations of macroeconomics rely on Domar aggregation: changes in a constant-returns-to-scale index are approximated by a sales-weighted average of the changes in its components. 1 Hulten (1978), building on the work of …
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.

Theorem 1.1 (Hulten) Let l i denote industry i’s sales as a share of output, then dlogC dlogAi = l i: 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.

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 Intresseanmälan.
