Hỗ trợ doanh nghiệp trong dịch Covid-19 phải liệu cơm gắp mắm

ôi dào, "targeting takes time, is difficult",

làm theo lời khuyên của gs mankiw, trợ cấp doanh nghiệp/người dân không phải ex ante (trước sự kiện) mà là ex post (sau sự kiện) nhé...

Let’s send every person a check for X dollars every month for the next N months. In addition, levy a surtax in 2020 (due in April 2021) equal to N*X*(Y2020/Y2019), where Y2020 is a person’s earnings in 2020 and Y2019 is a person’s earnings in 2019. The surtax would be capped at N*X.

Under this plan, a person whose earnings fall to zero this year keeps all of the social insurance payments and does not pay the surtax. A person whose earnings fall by half keeps half of the payments and returns half. A person whose earnings remain the same (or increase) returns everything: They will have just gotten a short-term loan.

Of course, there is an implicit marginal tax rate in this scheme. If Y2020 is less than Y2019, each dollar of earnings in 2020 faces an additional marginal tax rate of N*X/Y2019. A hardcore supply sider might object. But at this moment in history, social insurance is more pressing than avoiding the distortionary effects of taxes. One might even argue that, considering the externalities associated with leaving home to go to work in this time of contagious pandemic, a higher marginal tax rate might be efficient.
