  1. Notes: Model 1 ignores sector-specific attributes of the various jobs, while Model 2 distinguishes between jobs in the public and the private sectors. SML estimates are based on 50 draws from the distribution of the random effects in each model. DHI denotes disposable household income. ζ m , and ζ f are random effects for heterogeneity in preferences of husbands and wives, respectively. Asterisks denote *a p-value between 5% and 1% and **a p-value below 1%.
