If one person gives a euro to Ukraine, the result is €1.

If two people give 2 each, it is €4.

If 3,000 give 3,000 each, it is 9 million.

PolEconEnv 2025 - Program Program

A very interesting workshop on the political economy of the environment @univie.ac.at has just ended. Very inspiring presentations and discussions with great people. Thank you Alexandra Brausmann, Andrei Kalk, and Gerhard Sorger for organizing!

What does the world need the most?
It needs more focus on how sustainable policies can become politically feasible.
Partha Dasgupta is thus kicking off our conference on this topic today:
www.gsb.stanford.edu/events/polit...

Excited to present at the Political Economics of Environmental Sustainability Conference at Stanford GSB! 🌍💡

Looking forward to two days of insightful discussions on the intersection of politics, economics, and the environment.

Check out the full agenda here:

Political influence on international climate agreements with border carbon adjustment We study the influence of industrial lobbying on national climate policies and the formation of an international environmental agreement if the coalit…

If lobbying by trade-exposed polluting companies is strong, an interplay between border carbon adjustments (@carolynfischer.bsky.social doi.org/10.1016/j.je...) and lobby incentives can lead to larger stable coalitions, lower global emissions, and higher welfare.

Small climate clubs should not use trade sanctions Current pledges to reduce greenhouse gas emissions are insufficient to reach the temperature goal set out in the Paris Agreement and reaffirmed in the…

Small climate clubs should therefore not use trade sanctions.

Trade sanctions and the stability of climate coalitions We investigate whether trade sanctions against outsiders can foster climate cooperation in self-enforcing international environmental agreements if ou…

Trade sanctions against outsiders can foster cooperation (Nordhaus doi.org/10.1257/aer.15000001) even if outsiders retaliate. However, if retaliation takes place, there is a threshold effect: In small coalitions incentives to be a coalition member decrease whereas in large coalitions they increase.

Trump Orders U.S. Exit From the Paris Agreement on Climate (Gift Article) The United States will be one of only four countries outside the Paris Agreement, which is designed to reduce global greenhouse gas emissions.

Trump pulling out of the Paris Agreement again underscores the need for an international climate agreement that reduces free rider incentives.

Some insights about trade measures to enforce cooperation from my research:

Income Inequality and Political Polarization - RSERC presentation

It was a pleasure to have @waldomarz.bsky.social visiting us @pecan-research.bsky.social @humboldtuni.bsky.social this week for productive collaboration, constructive discussions, and an interesting presentation in the RSERC seminar today.

We hope you enjoyed your stay as much as we did 😊!

This is true. It just seems that these initiatives are not too stable once political sentiment turns against climate policies.

Financial markets need credible expectations concerning future climate policies/regulation in order to steer investments towards carbon neutrality. This might be unpleasant but is actually not really surprising.

Hi Paul, thanks a lot! Good to see you here as well :)

Oil Companies Skip Auction for Arctic Refuge Drilling Rights Oil companies declined to bid in a US government auction for drilling rights in the Arctic National Wildlife Refuge, as industry interest wanes in a region that’s rich with crude but difficult to deve...

When oil companies are reluctant to drill, it can reflect their expectations that there will be a time after Trump, and investments today can be stranded assets at that time:
