The Patient Protection and Affordable Care Act (ACA) contains substantial new requirements aimed at increasing rates of health insurance coverage. Because many of these provisions impose additional costs on the states, officials need reliable estimates of the likely impact of the ACA in their state. To demonstrate the usefulness of modeling for state-level decisionmaking, RAND undertook a preliminary analysis of the impact of the ACA on five states-California, Connecticut, Illinois, Montana, and Texas-using the RAND COMPARE microsimulation model. For Montana, the model predicts that, in 2016 (the year that all of the provisions in the ACA related to coverage expansion will be fully implemented), the uninsured rate in Montana will fall to 3 percent; without the law, it would remain at 18 percent. The model projects that total state government spending on health care will be 3 percent higher for the combined 2011-2020 period because of the ACA.
《患者保护与平价医疗法案》（ACA）包含旨在提高医疗保险覆盖率的大量新要求。由于其中许多条款给各州带来了额外成本，官员们需要对ACA在本州可能产生的影响进行可靠估计。为证明建模对州一级决策的有用性，兰德公司利用兰德比较微观模拟模型对ACA在加利福尼亚州、康涅狄格州、伊利诺伊州、蒙大拿州和得克萨斯州这五个州的影响进行了初步分析。对于蒙大拿州，该模型预测，在2016年（ACA中所有与覆盖范围扩大相关的条款将全面实施的年份），蒙大拿州的未参保率将降至3%；若没有该法律，这一比例将维持在18%。该模型预计，由于ACA，在2011 - 2020年的合并期间，州政府在医疗保健方面的总支出将高出3%。
