I estimate a model that allows diversification decisions to affect future productivity. I apply the model to a panel of U.S. manufacturing firms to measure the impact of diversification on productivity. My estimates suggest that diversification plays a key role in explaining differences in productivity across productive units and time. The average productivity effect of diversification is estimated to be positive at the productive unit level. However, the effect varies considerably across productive units and sectors of activity, depending crucially on already attained productivity.</p>","PeriodicalId":47963,"journal":{"name":"Journal of Industrial Economics","volume":"72 2","pages":"685-728"},"PeriodicalIF":1.3,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138496895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building on hedonic models of differentiated product demand, we develop an empirical hedonic model of labor demand and apply a two-stage nonparametric procedure to recover worker and firm heterogeneities. In the first stage we recover unmeasured worker quality by estimating market-specific hedonic wage functions nonparametrically. In the second stage we infer each firm's WTP parameters for worker attributes by using first-order conditions from the demand model. We apply our approach to quantify inter-industry wage differentials on the basis of individual data from the NLSY79 and find that worker quality accounts for approximately two thirds of the inter-industry wage differentials.</p>","PeriodicalId":47963,"journal":{"name":"Journal of Industrial Economics","volume":"72 1","pages":"459-515"},"PeriodicalIF":1.3,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/joie.12361","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136229846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We study this trade-off in the gasoline market by exploiting an alcohol sales prohibition at stations as an exogenous shifter of add-on availability. Gasoline margins drop by 5% during the prohibition. The effect is mediated by shop variety and competition.
