Allowing extra knots into the earnings-housework relationship additionally we can explore more fully the form associated with the relationship that is non-linear spouses’ earnings and their amount of time in housework.
Outcomes For Control Variables
in every models, an initial son or daughter is related to the average enhance of approximately 3.5 hours each week of wives’ housework, although the improvements of 2nd and 3rd kiddies have actually significant, but smaller positive associations with housework time. Both in the cross-sectional and panel models, spouses’ housework hours decline modestly with increases within the chronilogical age of the youngest son or daughter. Help for the time access theory is weak in this test, as alterations in neither husbands’ nor wives’ regular work market hours are dramatically related to alterations in wives’ time in housework when you look at the panel models.
Our specification checks concentrate on the panel models with all the specification that is flexible of’ earnings . We check both whether our email address details are robust to alternative model requirements and whether or not the outcomes hold for subgroups considering competition, training, age, marital status, and parental status, and for findings from various cycles. We discuss our alternative model specs together with leads to increased detail in this part (full outcomes offered by the authors upon demand).
One review regarding the preceding outcomes may be they are the artifact of either an insufficiently versatile specification for the spouse’s profits or general earnings, or of this quantity and placements associated with knots when you look at the linear spline model. To deal with the concern that is first we give consideration to models that included the husband’s profits along with the spouse’s as being a linear spline, along with models that specify both the spouse’s profits and partners’ general profits as linear splines, constantly selecting knots that approximately divide the test into quartiles.
