At the same time the U.S. experienced dramatic changes in the structure of households due to increased female labor force partici- pation. I show that changes in the household structure and corresponding changes in labor supply behavior can explain the labor productivity puzzle. I build a model with heterogeneous one- and two-earner households and aggregate technology shocks and calibrate it to the current U.S. data. I impose the household structure change in the model and show that the behavior of labor productivity changes from procyclical to countercyclical, as in the U.S. I also show that individual labor supply volatility depends on the role of the earner in the household. Increase in the proportion of multiple-earner households leads to increase in aggregate labor supply volatility.application/pdfengBusiness cyclesFamily labor supplyMultiple-earner householdsworking paperC68E32E24J22Economíaopen access
