本文估计了医疗补助计划的保费对计划受益人登记时间的影响。低收入家庭是否以及如何参与医保交易和各州的医疗补助计划，在很大程度上取决于他们将面临的保费结构和金额。我利用威斯康星州医疗补助计划结构的不连续性来确定保费对低收入家庭入学的影响。我使用了一个3年的招生数据管理小组来估计这些影响。我发现，保费从每月0美元增加到10美元，会减少1.4个月的注册时间，并使全年继续注册的可能性降低12个百分点，但保费金额的其他离散变化不会影响注册，或者影响要小得多。我没有发现任何证据表明，计划的参与者故意减少劳动力供应，以避免保费。(C) 2014 Elsevier B.V.版权所有
This paper estimates the effect that premiunis in Medicaid have on the length of enrollment of program beneficiaries. Whether and how low income-families will participate in the exchanges and in states' Medicaid programs depends crucially on the structure and amounts of the premiums they will face. I take advantage of discontinuities in the structure of Wisconsin's Medicaid program to identify the effects of premiums on enrollment for low-income families. I use a 3-year administrative panel of enrollment data to estimate these effects. I find an increase in the premium from 0 to 10 dollars per month results in 1.4 fewer months enrolled and reduces the probability of remaining enrolled for a full year by 12 percentage points, but other discrete changes in premium amounts do not affect enrollment or have a much smaller effect. I find no evidence of program enrollees intentionally decreasing labor supply in order to avoid the premiums. (C) 2014 Elsevier B.V. All rights reserved.
