By let's assume that monetary resources, of either the home or the specific, facilitate declines in spouses’ housework time at a rate that is constant current models have not permitted when it comes to chance for a non-linear relationship between spouses’ earnings and their housework time. Compensatory gender display theory has, up to now, been tested by including both linear and quadratic terms for partners’ general profits and examining the indication and need for the quadratic term. If, nonetheless, the connection between wives’ absolute earnings and their amount of time in housework is non-linear, constraining the connection between absolute profits and housework become linear can result in a spurious non-linear relationship between the share of home earnings spouses offer and their housework hours. It is because wives’ absolute profits are definitely correlated using their share of household earnings.
We utilize an even more flexible specification of spouses’ absolute profits – a linear spline – to gauge the relationship between spouses’ share of home earnings and their housework hours.
Compensatory gender display is hypothesized to possess power that is explanatory after accounting for any other predictors of partners’ housework time, including their demographic traits, work market hours, and absolute profits. Therefore, if this concept because it happens to be articulated by Brines as well as others is proper, the relationship that is quadratic spouses’ relative earnings and their housework time must not vanish when a far more versatile specification of spouses’ absolute profits is introduced towards the model.
