The economic crisis triggered by COVID-19 has caused a world-wide economic downturn, and the deepest GDP contraction in Latin America since the beginning of the XX century. One of the most dramatic outcomes of the crisis is the increase in poverty, but its extent will remain unknown until household income data is collected and analyzed. We propose a simple approach to provide early estimates, micro-simulating the short-run effect of the crisis on the poverty rate. It combines household level micro-data, estimates on the feasibility of working from home, information on key public policies (e.g., cash-transfers, unemployment insurance), and forecasts of GDP contraction. This approach, which can be easily adapted and applied to different countries, allows to the current poverty level and the poverty-reducing effect of public policies, while providing full micro-macro consistency between heterogeneous impacts on households and the shock to aggregate GDP. Moreover, it enables to estimate the effect on informal and self-employed workers, of utmost importance in developing countries. We illustrate the methodology with an application for Uruguay, finding that during the first full trimester of the crisis, the poverty rate grew by more than 38%, reaching 11.8% up from 8.5%. Moreover, cash transfers implemented by the government in the period had a positive but very limited effect in mitigating this poverty spike, which could be neutralized with additional transfers worth under 0.5% of Uruguay's annual GDP.
新冠疫情引发的经济危机导致全球经济衰退,也是20世纪初以来拉丁美洲国内生产总值收缩最为严重的一次。这场危机最显著的后果之一就是贫困加剧,但在收集并分析家庭收入数据之前,贫困加剧的程度仍不得而知。我们提出一种简单的方法来提供早期估算,通过微观模拟危机对贫困率的短期影响。该方法结合了家庭层面的微观数据、对居家工作可行性的估算、关键公共政策(如现金转移支付、失业保险)的信息以及国内生产总值收缩的预测。这种方法可以轻松调整并应用于不同国家,有助于评估当前的贫困水平以及公共政策的减贫效果,同时在家庭层面的异质影响与国内生产总值总量冲击之间实现完全的微观-宏观一致性。此外,它还能够估算对非正规就业者和个体经营者的影响,这在发展中国家至关重要。我们通过乌拉圭的案例来说明该方法,发现在危机的第一个完整季度,贫困率增长超过38%,从8.5%升至11.8%。此外,政府在此期间实施的现金转移支付在缓解贫困激增方面起到了积极但非常有限的作用,通过额外发放价值不到乌拉圭年度国内生产总值0.5%的转移支付就可以抵消这一作用。
