Slimme kilometerheffing levert volgens nieuwe studie veel meer op dan ze kost

Recently the President ordered that coal generators don’t need to comply with the Mercury and Air Toxics Standard (MATS). My forthcoming JPE paper with Gautam Gowrisankaran and Wendan Zhang on uncertainty surrounding MATS, so it seems like it’s time for a thread! www.whitehouse.gov/presidential...

Happy to share our piece in Microeconomics Insights on geographic entry restrictions and monopoly, based on our analysis of notary lawyers.

#econsky What is, in your opinion, the biggest question IO has credibly settled? Seems most of our contributions are either (a) fancy methods; (b) negative results (e.g. don't regress price on HHI); (c) narrow in scope (yogurts, etc); or (d) contested (have markups actually risen?)

Waarom een Musk misschien nuttiger zou zijn in België dan de VS met onze loonnormwet & loonindexering, wet op sluitingsuren, wet op verkopen met verlies, koopjeswet, vestigingswet voor apothekers, enz… m.standaard.be/cnt/dmf20241...
