|July 2015||Aggregating Elasticities: Intensive and Extensive Margins of Female Labour Supply|
with Orazio Attanasio, Peter Levell, Hamish Low: w21315
We estimate labour supply elasticities at the micro level and show what we can learn from possibly very heterogeneous elasticities for aggregate behaviour. We consider both intertemporal and intratemporal choices, and identify intensive and extensive responses in a consistent life-cycle framework, using US CEX data. There is substantial heterogeneity in how individuals respond to wage changes at all margins, both due to observables, such as age, wealth, hours worked and the wage level as well as to unobservable tastes for leisure. We estimate the distribution of Marshallian elasticities for hours worked to have a median value of 0.18, and corresponding Hicksian elasticities of 0.54 and Frisch elasticities of 0.87. At the 90th percentile, these values are 0.79, 1.16, and 1.92. Responses at ...
