The Dutch government implemented two changes to the taxation of intergenerational transfers aimed at mortgage down payments and prepayments. We identify the effects of these tax exemptions on prepayments and inter vivos transfers separately by taking advantage of the changes in policy design. The policy changes resulted in two expansions of tax‐exempt transfers, which increased the probability of receiving such transfers, translating into a modest increase in prepayments. Initially, the amounts prepaid increased by a similar magnitude, while the second policy change only resulted in an increase in the amounts being transferred but not the prepayments. The macroprudential policy goal was to reduce the number of underwater mortgages, but the policy was too generic and did not help to achieve this. The prepayments triggered by the policy change increased mostly for borrowers with low original loan‐to‐value ratios, implying that most transfers were made from wealthy parents to housing‐rich children.
荷兰政府对代际转移税实施了两项改革,针对的是抵押贷款首付款和预付款项。我们通过利用政策设计的变化,分别确定了这些免税对提前支付和体内转移的影响。政策变化导致免税转移的两次扩大,这增加了接受这种转移的可能性,转化为预付款项的适度增加。最初,预付的数额增加了类似的幅度,而第二次政策变动只增加了转移的数额,而没有增加预付的数额。宏观审慎政策的目标是减少资不抵债抵押贷款的数量,但该政策过于笼统,无助于实现这一目标。政策变化引发的提前还款增加主要针对原始贷款价值比较低的借款人,这意味着大多数转移都是从富有的父母转移到住房富裕的孩子身上。

Safe at Last? Late Effects of a Mass Immunization Campaign on Households' Economic Insecurity 终于安全了?大规模免疫运动对家庭经济不安全的后期影响

We study the effects of receiving immunization from COVID‐19 on households' economic insecurity. To provide causal estimates we use a fuzzy regression discontinuity design which takes advantage of the UK's immunization plan. The plan was primarily based on age, granting differential eligibility to proximate cohorts. Our estimated local average treatment effect indicates that the share of households who declared being economically insecure dropped by 41 percentage points among those who received the vaccine due to the eligibility criteria. Using a difference‐in‐discontinuity design we next document that immunization was more salient for women as well as for large households and those with children. Our results suggest that the mass immunization campaign against COVID‐19 had relevant short‐run economic effects, well beyond its expected impact on people's health.
我们研究了接受COVID - 19免疫接种对家庭经济不安全感的影响。为了提供因果估计,我们使用模糊回归不连续设计,该设计利用了英国的免疫计划。该计划主要基于年龄,对接近的队列给予不同的资格。我们估计的当地平均治疗效果表明,根据资格标准,在接受疫苗接种的家庭中,宣布经济不安全的家庭比例下降了41个百分点。采用差异-非连续性设计,我们接下来证明免疫接种对妇女以及大家庭和有孩子的家庭更为突出。我们的研究结果表明,针对COVID - 19的大规模免疫运动具有相关的短期经济效应,远远超出其对人们健康的预期影响。

Inequality Measurement and The Rich: Why Inequality Increased More Than We Thought 不平等测量与富人:为什么不平等的增长比我们想象的要多

Many standard inequality measures can be written as ratios with the mean in the denominator. When one income moves away from equality, both the numerator and the denominator may vary in the same direction and such indices may decrease. This anomalous behaviour is not shared by median-normalised inequality measures developed in this paper, where the mean at the denominator is replaced by the median. However, median-normalised inequality measures do not respect the principle of transfers. We show that the absolute Gini and the mean logarithmic deviation, or second Theil index, are the only measures that both avoid anomalous behaviour when one income is varied and also satisfy the principle of transfers. An application shows that the increase in inequality in the United States over recent decades is understated by the Gini index and that the mean logarithmic deviation index should be preferred in practice.
许多标准的不等式度量可以写成以平均值为分母的比率。当一种收入偏离平等时,分子和分母都可能朝着同一方向变化,这些指数可能会下降。本文中开发的中位数归一化不等式测量方法不具有这种异常行为,其中分母的平均值被中位数取代。然而,中位数归一化的不平等衡量并不尊重转移原则。我们表明,绝对基尼系数和平均对数偏差,即第二泰尔指数,是唯一既能避免一种收入变化时的异常行为,又能满足转移原则的指标。一项应用表明,基尼指数低估了美国近几十年来不平等程度的增加,在实践中应首选平均对数偏差指数。

Empirical research on poverty today often goes beyond a focus on income to consider other dimensions of well-being. However, relatively few multidimensional poverty measures explicitly consider time, despite its particular relevance to women’s double burden of paid and unpaid work. We construct a bivariate relative poverty line between income and leisure, based on their joint distribution in the population. Because the strength of the dependence between income and leisure influences the vulnerability to poverty, we incorporate distributional regression into copula models. Utilizing the 2018 Mexican National Survey of Households, Income and Expenses, we investigate differences in bidimensional poverty with respect to gender and ethnicity. We find that the fraction defined as bidimensional poor is 18 percentage points higher than the poverty rate computed from separate time and income measures. Those below the relative but above the absolute poverty line are primarily non-indigenous women whose poverty is made visible by our approach.
如今,对贫困的实证研究往往超越了对收入的关注,转而考虑福利的其他方面。然而,相对较少的多层面贫穷措施明确考虑到时间,尽管它与妇女有偿和无偿工作的双重负担特别相关。根据收入和闲暇在人口中的联合分布,我们构建了收入和闲暇之间的双变量相对贫困线。由于收入和闲暇之间的依赖关系的强度会影响对贫困的脆弱性,我们将分配回归纳入到联结模型中。利用2018年墨西哥全国家庭、收入和支出调查,我们调查了性别和种族方面的二维贫困差异。我们发现,被定义为二维贫困的比例比单独以时间和收入衡量的贫困率高出18个百分点。那些低于相对贫困线但高于绝对贫困线的主要是非土著妇女,她们的贫困通过我们的方法得以显现。
