Their analysis, published as Netspar Discussion Paper No. 10-2014-044 led Been and Van Vliet to the conclusion that part-time employment is negatively related to labor market withdrawal of older men. This relationship is less strong among women. In addition, they found that part-time employment at older ages does not decrease the average actual hours worked. Furthermore, the results show a positive relationship between unemployment among older workers and early retirement similar to previous studies.
As a wider implication, our results suggest that facilitating part-time work might contribute to higher labor market participation among older workers at the extensive margin. However, facilitating part-time employment could also induce a reduction in working hours among persons who would otherwise have remained working in full-time employment. Our analysis suggests that increases in part-time employment did not have negative effects on the labor supply at the intensive margin across countries. For men, the results even suggest clear positive effects. This indicates that part-time work schemes may actually increase the labor supply at both the extensive and the intensive margin at older ages.Source: Social Science Research Network Abstract (October 15, 2014)
