We compute the continuous cohomology of the Morava stabilizer group with coefficients in Morava E -theory, H ∗ ( G 2 , E t ), at p = 2, for 0 ≤ t < 12, using the Algebraic Duality Spectral Sequence. Furthermore, in that same range, we compute the d 3 -differentials in the homotopy fixed point spectral sequence for the K (2)-local sphere spectrum. These cohomology groups and differentials play a central role in K (2)-local stable homotopy theory, in particular for the analysis of the K (2)-local Picard group.","PeriodicalId":118579,"journal":{"name":"A Gentle Introduction to Homological Mirror Symmetry","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132944373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We document that almost half of the decline in aggregate agricultural employment was driven by new birth cohorts entering the labor market. We use data on educational attainment and compile a comprehensive list of policy reforms to interpret the di ff erences in agricultural employment across cohorts. We find that the increase in schooling led to a sharp reduction in the agricultural labor supply by equipping younger cohorts with skills more valued out of agriculture. Interpreted through a model of frictional labor reallocation, these facts imply that human capital growth accounts for about 20% of the global decline in agricultural employment. ∗ We thank Rachel Ngai for an insightful discussion of an early version of the paper.
