To bypass this difficulty, I propose to first approximate the local dynamics of a tractable auxiliary model and then apply regular perturbation to some of the parameters to reach the model of interest. This method is easy to implement with available packages and allows researchers to solve a wide class of DSGE models around a large subset of the state-space while still relying on the implicit function theorems. Exploiting these properties, the paper develops a simple algorithm to find an auxiliary model whose deterministic steady state equals the stochastic steady state of the model of interest and builds the perturbation solution around this point.

At equilibrium, aggregate technology is Neoclassical, with the quality of capital and the depreciation rate depending on selection. As investment distortions are corrected, selection increases, and both output per capita and welfare rise at the steady state. However, selection destroys existing production capacities, leading to transitional welfare losses. When calibrated to the US, the model shows that developing countries reducing investment distortions to US levels would experience substantial steady-state welfare gains, though transitional costs could absorb 70% to 76% of these gains. While the associated welfare gains from selection at steady-state are significant, between 10% and 23%, transitional costs largely offset these additional welfare gains.</div></div>","PeriodicalId":47890,"journal":{"name":"Review of Economic Dynamics","volume":"57 ","pages":"Article 101284"},"PeriodicalIF":2.3,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide evidence demonstrating the importance of a multisector perspective. Central to our mechanism is the decline in the relative price of the low-skill intensive sector driven by its faster productivity growth. This dampens wage gains for low-skill workers by lowering the price of their output relative to their consumption basket, which is further reinforced by shifting them into the sector where less weight is placed on their labor. We calibrate the two-sector model to the 1980–2010 U.S. economy and find this mechanism to be quantitatively important.
