In light of the recent attack on wealth tax proposals, its also interesting to look back a few years...
One meta reflection on the Piketty, Saez, Zucman and Auten & Splinter debate is the following. It suggests there is an attempt to reset, control or cast doubt on a narrative. On one side you have academics at a top US University, on the other hand, you have academic economists associated with the public sector. Another example is likely the "deaths of despair" narrative, but there are other narratives that may matter as well. I am curious what will be "next". I referred before to "operation cleanup" that is underway. You very much see the "stories" are being produced to give an impression of a cleanup. The other bit may be a "great narrative reset". In the UK political class a "centrist" consensus view that "austerity had to be done", but the problem was the "how" is emerging. I actually am not in disagreement here. Regarding the narrative reset are at least three factors to be considered. 1) data - informational dimension there may be a perception that public sector or central bankers lean on an informational or data advantage that gives authority to the assertions stemming from them. 2) expertise lets face it, many academics do not have the depth of subject matter experience or knowledge in certain areas. This is not to say that expertise or academics do not matter, we are very often a source and driver of innovation and innovative thinking that leaves its mark on what public sector then implements. 3) trust the public sector serves to the benefit of the society broadly, not any one specific group. But it implements and acts to implement laws and enforce regulation on behalf of the sovereign which, in Western societies, this is Parliament. That is at least the broad principle. The overt politicisation of the civil service at some level is the core that undermines trust in the public sector. But politics depriving the public sector of funding or the informational resources to work effectively. Highly concentrated and politicised media ecosystem, poorly trained journalists and heterogenous populations are a challenge here. How you communicate with different folks depends on their absorptive capacity. How people process information is very different. My coauthor Chris Roth is doing some nice work here highlighting this challenge -- the pervasiveness of stories rather than statistics. But, while we may appreciate stories, we like decision makers to focus on hard numbers, not narratives. Narratives can become a constraint or, selectively a tool. There may be naked interests that drive and shape narratives. There may just be opportunism. The changes in the media ecosystem due to technology, the increase of media filtering of information and the empowerment of individuals to become content creators is a blessing and a curse. As I commented in my keynote in June 2023 at with the EMM team at the EU's Joint Research Centre, (social) media complements individuals with narcissistic personality traits. Just like politics. I m hoping I will find the time or the conviction that it is worth to put this stuff in more organized writing. Its all scattered everywhere. But it is time to connect the dots of the strands in my research.

Asset monetization (tokenization), ever more pervasive passive demand for assets through index funds, combined with share class differentiation of ownership versus control effectively creates what may well become private control over what effectively may be perceived to be money supply. This requires the owners of control to uphold belief systems that underpin this passive demand, and one way to do that is to seek and expand private control over the platforms that steward attention (think: media ownership). I am deeply concerned that many economists engaging in discourse around wealth taxation are not aware of these developments.

This is a longer thread to connect some dots. It is so obvious to some to understand what "went wrong" in 2000s/2010s but as I keep saying deeds matter more than words. I will try to relate some academic work that speaks to this. This is also about understanding...

With AI we may now soon realise that: we have identified all human types/behaviors. There is nothing more to learn that can not be replicated with LLMs. I am hopeful that human ingenuity will proof us all wrong.

We will have to "rewrite history" at scale… when I speak about these issues I highlight how we have been hit with a technology shock that was not paired with expansion of adequate training under high powered incentive and pressures, this was the most... nitter.cf/michael_wiebe/status/2…

The set of what is possible expands, the set what is impossible shrinks. What principles we impose on the social dimension of this development reveals much about how we conceptualize human agency and freedom.

Security vulnerabilities are an essential part of the security infrastructure. As these go, suitable β€œreplacements” need to be found. Good old "trust", anyone? Trust, but (delayed) verification?

Every now and then it is useful to look back. In this article for The Globalist I provided a succinct overview of the incentive mix around Iran, now with added contextual data. In a high dimensional world, low dimensional narratives are dangerous -- yet they are pervasive...

🚨Understanding Migration Responses to Local Shocks New version of paper with @borusyak and Brian Kovak! 1/6 Many papers find that local labor demand shocks have sizable effects on wages and employment, but surprisingly small or imprecise effects on local population.

Back in November 2024 β€” and even until earlier this year β€” my analysis was that, while Trump was willing to sell out Ukraine, the payoff from normalizing relations with Russia was insufficient to cover the costs of capitulation. I’m afraid the politics have shifted. /1

🚨New Paper Alert🚨: Export controls aim to limit adversaries' access to military-relevant inputs. But firms, supply chains, and incomes adjust. The countries imposing controls pay a price too. Using new data, we quantify when and how they can be effective and thus whether the trade-offs are worth it. 🧡 1/

by corporatist players (see below). Here is how I'd nest both intuitions. Start from clear pro-climate electoral activation, i.e. voters who visibly reward climate action and punish inaction. Governments then have electoral incentives to buy the consent of carbon-intensive

Good economics should reach beyond people who have time to read the full paper. @lehanzhang_ built a beautiful interactive guide to our study of how poliricians polarize the public debates following mass shootings. Follow the evidence as you scroll: lehanzhang.com/research/addi…
