Starting to have friends and family ask how I feel about the alleged gang rape at Cornell as a faculty member. We'd like to believe our opinion does not matter, but it does enough to some that I'm compelled to share my views. Well, I'm pretty horrified. I'm sure I'm not the only one. A short thread.

As a reviewer I'm experiencing what feels like a doubling of reviewing requests. I'm not tracking my declines yet but will probably start soon.

Serious scholars have examined what happens when we change the number of H1-B visas issued.
Cities that get more H1-B immigrants subsequently see the wages of natives *rise* substantially.
Skilled immigrants bring new ideas, fill labor shortages and make us all more productive.

We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me.
We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

We argue that climate clubs show promise:
- A climate club with coordinated penalties could curb 68% of excess emissions from free-riding
-Unilateral carbon tariffs? Not nearly as effective

We study how trade policy can reduce global emissions. Unilateral carbon border taxes have limited efficacy at cutting foreign emissions. By contrast, coordinated trade penalties under a climate club prove highly effective. buff.ly/NEE3Uy8
