@Jackbmeyer Got it after seeing your tweet and started reading, great book!

[C.-Philipp Heller @CPhilHeller]

@RenaudFoucart Sure, but the reason there was a contest in the first place appears to be SpaceX lobbying. And then the government just picked the cheaper option (where rockets are not thrown away after each use).

[C.-Philipp Heller @CPhilHeller]

@RenaudFoucart The difference is that the government didn't one day decide to do industrial policy to get reusable rockets. Instead, SpaceX decided it wanted to do reusable rockets and then had to persuade an initially reluctant government to allow it to compete.

Alles unbestätigt, aber: Ich wäre auf die Begründung dafür gespannt, das Regelrenteneintrittsalter erst ab Jahrgang 1990 (!) auf 70 anzuheben. Besser als gar nicht, aber damit werden die Kosten des demografischen Wandels wie gehabt auf die derzeit junge Generation abgeladen.

@florianederer While the paper is interesting, I think it ignores the role of the antitrust authority. If merger reviews are at all informative about likely market power increase and efficiencies, then firms' selection into proposing merger will be affected:

@florianederer @philipagyapongk @drStuartGilmour @MiguelDelaney Apart from banning resale the initial allocation als needs to avoid giving out tickets on a first-come-first-serve basis, since touts/scalpers will always have a speed advantage due to bots. https://t.co/26uURsdsSb

@erinhengel Sure, that also happens. Some people trained as economists may work as data analysts. Often though, job titles are a bit fluid and so if you are doing a bunch of different things all related to economics, you can just ask for economist to be in your job title.

@erinhengel - Assessing performance of different price discovery venues
- Causal inference for various business decisions.

Sometimes you also get to write papers about it: https://t.co/jvUx9swLgz

@erinhengel Not working at Door Dash, but here are a few things economists in industry might be doing:
- Designing rules of auction-based trading platforms
- Developing algorithms to determine optimal reserve prices or price increments in online auctions
- Advising on auction strategy

I may be biased on this, but I agree with Renaud on this one.

@RenaudFoucart @TomJackSpencer All I can say is that I checked the websites of the consulates one or two years ago, and they were using a waitlist.

I had to leave IZA in other rough times. Never rejoined, but was happy to see its impressive development under @simon_jaeger. With his departure, Germany is leaving a terrible impression re science policy.

[C.-Philipp Heller @CPhilHeller]

Mergers that create the most efficiencies increase markups and concentration a lot, but are nevertheless good for consumers because they reduce prices.

My colleagues and I recently wrote about this here:

[Brian Albrecht @BrianCAlbrecht]

We all know concentration ≠ bad. Well, Economic Forces readers know that.

But are markups bad? We need to be careful.

Improving quality or decreasing costs are a great things! They may also create markups and profits https://t.co/TdabPvCAJk
