doi:10.1111/jors.12351engGiménez-Nadal, José IgnacioMolina, José AlbertoVelilla Gambó, JorgeSpatial distribution of US employment in an urban efficiency wage settingART-2018-102278We analyze whether ef¿ciency wages operate in urban labor markets, within the framework proposed by Ross and Zenou, in whichshirking at work and leisure are assumed to be substitutes. We useunique data from the American Time Use Survey (ATUS) that allowus to analyze the relationships between leisure, shirking, commuting, employment, and earnings. We con¿rm that shirking and leisureare substitutes, and present an estimate of this relationship, representing the only empirical test of the relationship between a worker’stime endowment and shirking at work. Our ¿ ndings point to the existence of ef¿ciency wages in labor markets.2018http://zaguan.unizar.es/record/7074010.1111/jors.12351http://zaguan.unizar.es/record/70740oai:zaguan.unizar.es:70740info:eu-repo/grantAgreement/ES/MINECO/ECO2012-34828JOURNAL OF REGIONAL SCIENCE 58, 1 (2018), 141–158All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
