This paper examines the labour supply behaviour of married women in France. A sequence of models is specified and estimated which incorporate different amounts of information on observed weekly hours. In all models the distinction is drawn between search and non-participation among non-workers. We provide extensive specification diagnostics, including Heckman-Andrews tests, as well as Hausman tests for the comparison of different handlings of the hours information. It turns out that distinguishing between part-time, full-time and long hours gives virtually the same results as treating observed hours as reflecting desired hours.
