Table 3.
Relative mate value and differential work effort. Part A assesses the relationship between husband’s (H) [wife’s (W)] mate value relative to other men [women] and (A1) the amount of time those husbands and wives engaged in work activities, and (A2) the relative amount of work engaged by husbands and wives within unions. Part B assesses the relationship between the relative mate value of spouses within unions and the same two sets of measures of time spent in work activities described for Part A. The statistically significant results are highlighted in bold, and those significant results that run counter to prediction are in italics. All numbers are standardized parameter estimates (β)
