In Sweden approximately 3% of annual births are conceived using assisted reproductive technologies (ART). In light of increasing use of ART in Sweden we estimate the lifetime future tax revenues of a child conceived by in-vitro fertilization (IVF) to establish whether public subsidy of IVF represents sound fiscal policy.
A modified generational accounting model was developed to calculate the net present value (NPV) of average investment costs required to achieve an IVF-conceived child. The model simulates direct lifetime financial interactions between the child and the Swedish government. Within the model we assume average direct financial transfers are made to the individual (eg, child allowance, education, health care, pension, etc). In return, the individual transfers resources to the government through taxation based on anticipated average earnings. The difference between direct transfers and gross taxes paid equals the net-tax contribution. Individual tax contributions were held constant in the model.
Based on average life-expectancy an individual born in 2005 will pay an undiscounted 32.5 million SEK in taxes to the Swedish government and receive 20.9 million SEK in direct financial transfers over their lifetime. When these figures are discounted and IVF costs are included in the analysis we obtain a lifetime NPV of 254,000 SEK with a break-even point at age 41 (the age of achieving a positive NPV) for an individual conceived through IVF.
Based on results presented here we conclude that State-funded IVF in Sweden does not negatively impact the long run fiscal budget. Conversely, over an average lifetime an IVF offspring returns a positive net value to the State.
在瑞典,每年约3%的新生儿是通过辅助生殖技术(ART)孕育的。鉴于ART在瑞典的使用日益增加,我们估算了通过体外受精(IVF)孕育的孩子未来一生的税收收入,以确定对IVF的公共补贴是否代表合理的财政政策。
开发了一种改进的代际核算模型,以计算孕育一个通过IVF出生的孩子所需的平均投资成本的净现值(NPV)。该模型模拟了孩子与瑞典政府之间一生的直接财务互动。在模型中,我们假设向个人进行平均直接财务转移(例如儿童津贴、教育、医疗保健、养老金等)。作为回报,个人根据预期平均收入通过纳税向政府转移资源。直接转移与缴纳的总税款之间的差额等于净税收贡献。模型中的个人税收贡献保持不变。
基于平均预期寿命,2005年出生的个人一生将向瑞典政府缴纳3250万瑞典克朗的未贴现税款,并获得2090万瑞典克朗的直接财务转移。当这些数字进行贴现并将IVF成本纳入分析时,我们得出通过IVF孕育的个人一生的NPV为25.4万瑞典克朗,盈亏平衡点在41岁(实现正NPV的年龄)。
根据此处给出的结果,我们得出结论,瑞典由国家资助的IVF不会对长期财政预算产生负面影响。相反,在平均一生中,通过IVF出生的后代为国家带来正净值。
