Relative Efficiencies and Comparative Advantages in Job Search
利用新进入劳动力和壮年工人的面板数据，估计在职与失业求职模型，发现失业求职对年轻人和低收入者略有效，但对成熟工人效果显著差于在职求职。
A model of employed and unemployed job search is estimated from a panel of new entrants into the labor force as well as prime-age workers. After investigating the relative efficiency of the two main search methods within a representative agent framework, the author estimates the model under a specification that encompasses comparative advantages using the quit/layoff distinction and pretransition earnings. Overall, the data indicate that unemployed search is slightly more effective for younger workers and, particularly, for those with low earnings but significantly less effective than employed search for mature workers.
