Cover of the paper "The Impact of Geopolitical Risks on the Resilience of Banks in the Banking Union" by Rainer Haselmann, Florian Heider, Luis Enrique Kaiser, Jonas Schlegel, and Tobias Tröger
How do rising geopolitical tensions affect Europe’s banks?
A new study by SAFE researchers prepared at the request of the European parliament finds that geopolitical shocks weaken capital.

When states like Colorado passed policies requiring employers to disclose salary information in job postings, what happened?
It increased competition, and raised wages, without harming employment or changing skill requirements.
Improved functioning of markets, helped workers.

This figure presents binned scatterplots of B/P and cumulative future stock returns from the regressions in Panels A and B of Table 3, with both variables residualized on the control variables and fixed effects (firm and quarter).
This study finds that passive ownership has weakened the traditional positive relationship between book-to-price ratios & future #stockreturns, known as the value effect.

In an interesting turn of events, US and Danish government came up with the same to help with the affordability crisis: longer mortgages!
That has sparked some backlash. But in the US, it seems the discussion is focusing on the wrong stuff.
Well, let’s try to learn from 🇩🇰.
This figure shows a distribution of the estimated coefficients for Pseudo_ Event_25km, derived from 500 iterations of placebo tests where we replace Event_25km with randomly generated pseudo-event dates (Pseudo_Event) and randomly selected treatment and control firms (Pseudo_Treat) in the baseline regression.
Extreme local environmental events & the cost of #debt: This study uses a difference-in-differences approach to examine how nearby extreme #environmental events affect firms’ debt costs.

This graph shows the evolution of physical yields (tons of output per hectare) for three crops in Brazil, using data from the Brazilian Census of Agriculture (1950 to 2017). Each dot indicates a separate observation. In each panel, the yield in 1970 is normalised to one. Data for soybeans are not available before 1970. It is often argued that returns to R&D are low in developing countries, making imported technologies a better path to growth. Yet technologies designed for frontier nations may not fit local conditions, limiting their productivity gains. This column studies Brazil’s Embrapa, a large public R&D effort to create agricultural innovation suited to Brazil’s ecology. Embrapa shifted research toward local needs and raised agricultural productivity by 110%, far outweighing its costs. Sustained, locally targeted R&D can be a key part of development policy.
Brazil's Embrapa programme - a large public #R&D effort to create agricultural #innovation - shifted research to local needs and raised agricultural productivity by 110%, far outweighing its costs.

This new QJE paper finds: excessive mobile app use among the youth is contagious and costly. Roommates’ app use boosts your own. Heavy app users get lower Grade Point Averages, earn less, sleep less, skip more class. Extending gaming limits to college students could raise wages.

- Spillovers come from other assignees, regions, and technology fields
- Early application disclosure after AIPA reduces but does not eliminate the licensing effect
We analyze how licensing of government inventions affects follow-on innovation, focusing on NASA. We combine NASA Technology Transfer Program data with US patent data and Federal Register announcements.
Key findings
- Exclusive licensing announcements are associated with higher follow-on invention
🚨 Publication alert 🚨
I am happy to announce that the paper
“Reaching for the society: The commercialization effects of NASA technology licensing” (with @anjaroesner.bsky.social) will appear in the December issue of Research Policy!!

New research by Pierre Azoulay, Danielle Li, Bhaven Sampat and me.
Earlier this year, the President’s budget proposed a 40% cut to the budget of the NIH. This motivated us to ask: what if the NIH had been 40% smaller?
Could anyone share examples of well-designed and practical LaTeX presentations that are suitable for lecture slides? I am looking for some inspiration. #TeachEcon
