Here is the link to full report and a link to a twitter thread that summarizes the report (I strongly suggest you read the niskanen center article). The overarching theme in this report is the importance of monopsony power in understanding labor markets, and the fact that labor markets are rather uncompetitive. So uncompetitive, in fact, that the report estimates that wages are ~20% lower, relative to a more competitive labor market.

That said, the policy recommendations made by the report are rather limited, such as passing the PRO act, stronger antitrust enforcement, and raising the minimum wage. Two of which have been stalled in congress and one that is already being pursued. The report also makes a strong argument that labor market frictions are the cause of this monopsony, but does not recommend any policies that tackle this. Policies such as strong unemployment insurance (replacing >40% of income), greater funding for employment services and ALMP, increasing worker bargaining power via sectoral bargaining (unions negotiating wages on a sector wide level), co-determination, and banning non-compete clauses (which would make a big difference considering 1/5 workers have signed a non-compete agreement).

Now, this isn't in the report, but Co-determination is a really underrated policy that isn't talked about enough in the USA. Nearly all of Europe has it, and I think it would significantly improve worker bargaining power in the USA. Evidence has shown its effects to be positive, though small, but this is most likely due to the fact that countries with strong codetermination laws also have strong unions that negotiate wages industry wide, so there isn't as much of a chance for employee representatives to help. USA does not have this, so there is good reason to believe it would be much more helpful here. Senator Warren currently does have a co-determination in her platform, and this article by Matt Yglesias summarizes it quite nicely. We should try to get this passed.
