Nonetheless I'd like to use this time to study how market power and tacit collusion interact with an inflationary environment. THE END - thank you for your patience with my non-knowledge on how to make a thread on this platform

3. IO folk, myself included, helped push back against the seller's inflation story (aka greedflation). The narrative that market power is the cause of inflation simply does not pass the smell test. I'm glad we did. -->

Alon Eizenberg @aloneizenberg.bsky.social · 01/12/2023

What do you do when costs fall? Well, nothing. That is a wonderful focal point for a cartel to stick with. No reason to lower prices until somebody else does. 2. Price rigidity has many reasons and manifests itself in manners beyond Rockets & Feathers. -->

Alon Eizenberg @aloneizenberg.bsky.social · 01/12/2023

A few important clarifications and caveats: 1. Rockets & Feathers do not necessarily reflect a lack of competition. Could also result from information issues (e.g. Cabral & Fishman 2012). Nonetheless, tacit collusion remains an important explanation. -->

Alon Eizenberg @aloneizenberg.bsky.social · 01/12/2023

Instead, prices stabilize, which indeed brings down inflation. But under more competitive conditions, prices would fall back, at least partially, rather than just stabilize. Inflation would cool off faster, interest rates could be lower. -->

Alon Eizenberg @aloneizenberg.bsky.social · 01/12/2023

I'm talking about Rockets and Feathers. A refined statement would say: Big corporations jacked up prices when commodity prices were rising, we get that. But when the upstream cost pressures subside, prices do not go back down. -->

Alon Eizenberg @aloneizenberg.bsky.social · 01/12/2023

President Biden's statement that firms should lower prices because inflation is down caught much fire, and rightfully so. many problems there. But there is an underlying core to this statement that we should take seriously. ->

We tend to focus on the short-term trends, but it's worth taking a step back: Inflation has come down a *lot* from its peak. Headline now down to 3% y/y. Core at 3.5%. Those are still above the Fed's target and prepandemic levels, but it's a radically different story than a year ago.

It's a big improvement—replacing a kWh of Coal with a kWh of Gas reduces C02 emissions by more on average than replacing a kWh of Gas with Wind/Solar (though methane leaks offset some of this) Also thank you! I tried to pick the colors for colorblind accessibility and I'm glad they're working

A table showing C02 emissions by electricity generation source in the US. Coal power plants emit 2.26 pounds of C02 per kWh while Natural Gas power plants release 0.97 pounds of C02 per kWh
