More on Cash for Clunkers

Max Auffhammer writes to keep me current on Cash for Clunkers. (Thanks Max!)

Mathew Kahn does his own back-of-the envelope calculation.

And Christopher Knittel does more than a back-of-the-envelope calculation.

I think my calculations, though stated a little different, are very much in a ballpark of what these guys found. That's kind of cool because I threw those numbers together pretty quickly. Given that, I think I'll gloat a little: I beat these guys by a week!

Nonlinear Temperature Effects Indicate Severe Damages to U.S. Crop Yields Under Climate Change

It's been a long haul, but my coauthor Wolfram Schlenker and I have finally published our article with the title of this blog post in the Proceedings of the National Academy of Sciences . We've been told that it would show up on the early-edition website this week. It hasn't shown up there yet so I guess it will come out tomorrow [Friday 8/28], probably late afternoon EST. UPDATE: You can find the article here . We set out to develop a better statistical model linking weather and U.S. crop yields for corn, soybeans and cotton, the largest three crops in the U.S. in production value. Our major new finding is that (by far) the best predictor of yield is a measure of extreme heat: how much temperatures exceed about 29C (84F) during the growing season. The threshold varies somewhat by crop--29C is the threshold for corn. Below this threshold, warmer temperatures are more beneficial for yields, but the damaging effects of temperatures much above 29C are staggeringly large. A

Renewable energy not as costly as some think

The other day Marshall and Sol took on Bjorn Lomborg for ignoring the benefits of curbing greenhouse gas emissions.  Indeed.  But Bjorn, among others, is also notorious for exaggerating costs.  That fact is that most serious estimates of reducing emissions are fairly low, and there is good reason to believe cost estimates are too high for the simple fact that analysts cannot measure or imagine all ways we might curb emissions.  Anything analysts cannot model translates into cost exaggeration. Hawai`i is a good case in point.  Since moving to Hawai`i I've started digging into energy, in large part because the situation in Hawai`i is so interesting.  Here we make electricity mainly from oil, which is super expensive.  We are also rich in sun and wind.  Add these facts to Federal and state subsidies and it spells a remarkable energy revolution.  Actually, renewables are now cost effective even without subsidies. In the video below Matthias Fripp, who I'm lucky to be working w
