🔧Model of firm organization + micro data (🇩🇪+🇵🇹)

👉Yes! Importance of coworker interdependencies has ⬆️ & this helps explain⬆️between-firm inequality

👇Summary-🧵 Image Modern production frequently involves teamwork between employees specialized in different tasks — and we know that this division of labor is important for efficient production!

I occasionally tweet summaries of papers I find particularly interesting/important/enjoyable or collect a number of thematically related pieces in a thread.

This 🧵-of-🧵 collects them. @DeRidderMaarten's paper argues that a substantial fraction of the widely discussed post-GFC slowdown in productivity is an endogenous effect of that crisis, operating through a decline in productivity-enhancing investment intensity.

❓How unequal is consumption between the top 0.01% and the median adult, before/during/after lockdowns?

👉How to answer this + many other Qs using granular bank transaction data from Spain in this paper by Carvalho et al.

❗️Amazing what 3bn transactions can shed light on

🧵 𝐂𝐨𝐧𝐭𝐞𝐱𝐭. Despite recent advances, national statistical agencies mostly rely on traditionally structured survey data + slow-moving censuses. But there also exist naturally occurring transaction data, arising through the decentralized activity of millions of economic agents.

New work by @SorryToBeKurt & M Hagedorn stimulated several interesting exchanges about monetary + fiscal policy and their effects on inflation. Here is a thread pulling together the different strands to make the ideas more accessible.

To me: #EconTwitter at its best. @SorryToBeKurt's original thread summarized a new WP that analyzes the monetary and fiscal response to the COVID-19 pandemic, and specifically how to deal with the debt burden, through the lens of the Heterogenous-agent New Keynesian (HANK) model

#MMT has received a ton of attention on #econtwitter and beyond over the past few months, but my impression is that exchanges b/w MMT-folks are often not v productive. Following thread covers 4 "meta observations" trying to pinpoint issues and suggest more productive ways. 1/n Summary: 1) terminological differences, 2) unstated premises, 3) attitudes/missing respectful treatment, and 4) a lack of mathematical models in the debate represent important limitations => formalization of debate seems crucial. 2/n
