Sector differences in prosocial motivations and behaviors among workers receives a great deal of attention in public administration scholarship. Extant literature consistently finds public sector workers are more likely to engage in prosocial behaviors, such as volunteering, than their peers in the private sector. Less attention has been paid to the sector gap in volunteerism along the intensive margin. Using time-diary data, which accounts for potential social desirability bias, from a nationally representative sample, this study investigates the gap between public sector workers and their private sector counterparts. The results suggest that public sector workers spend much more time, on an average day, volunteering than observably similar private sector peers, and the difference cannot be explained by other observable differences between public and private sector workers. The gap in volunteer intensity is largest at the local level and among teachers. The implications of these results for research and practice are discussed.

给予时间：检查志愿服务强度的部门差异

工人之间亲社会动机和行为的部门差异在公共行政奖学金中受到了极大的关注。现有文献一致发现，与私营部门的同龄人相比，公共部门的工作人员更有可能参与志愿服务等亲社会行为。对密集边缘志愿服务部门差距的关注较少。本研究使用来自全国代表性样本的时间日记数据，这些数据说明了潜在的社会期望偏差，调查了公共部门工人与其私营部门同行之间的差距。结果表明，公共部门工作人员平均每天花在志愿服务上的时间比明显相似的私营部门同行要多得多，并且这种差异不能用公共和私营部门工人之间其他可观察到的差异来解释。志愿者强度的差距在地方一级和教师之间最大。讨论了这些结果对研究和实践的影响。
