I'm guessing a lot of libertarians are going to be upset at this.

Bit surprising to be honest.

The Clark medal is often the early stepping stone to an eventual Nobel in economics. Can't say I'm too big of a fan of his income inequality work, but his tax evasion stuff is interesting. Even just using the IRS' estimates of the tax gap (the difference between taxes owed and taxes paid) from the National Research Program, the US tax gap reached $630 billion in 2019. It is on pace for a $7 trillion gap over the next decade. This is predominantly from higher income persons. Audits of these taxpayers are far more resource intensive and require highly skilled auditors and forensic accountants.

Zucman has done a lot with Saez, a former Bates Clark winner himself in 2009.
