α: calibrated so average coauthorship-adjusted count equals average raw count
With the American Time Use Survey 2003-15 we show that both non-workers and workers with higher household incomes spend less time on two quantitatively important time-intensive activities, sleep and TV-watching. This finding cannot be explained by the standard (Becker, 1965) ”commodity production” model. We modify that model to allow both substitution between time and goods in household production and substitution among commodities in utility functions, which rationalizes these results and suggests a way forward for empirical work on household behavior.
