Welfare Use when Approaching the Time Limit
首次在实证中纳入剩余资格月数这一关键因素，估计1996至2003年间福利时间限制使使用率下降25%，其中约五分之一源于行为响应。
Abstract Time limits reduce caseloads directly by cutting off benefits after a time-limited usage, but may also provide families with an incentive to reduce welfare use in order to conserve their benefits. Both effects depend on the stock of remaining months of eligibility. This is the first empirical study to incorporate information on this crucial determinant of takeup and eligibility under time limits. Accounting for the potential endogeneity of an individual’s past use, time limits are estimated to have decreased welfare use by 25 percent between 1996 and 2003. Roughly one-fifth of this reduction is due to behavioral responses.
