Check out my very talented student on the market this year! Her job market paper is both innovative theoretically and on a topic of timely practical relevance--how should a platform trade-off the goals of producing the best-fitting matches without creating oversupply?

Climate change is an unfortunate reality. But how can farmers, who make up a considerable part of India's workforce, adapt to extreme heat events? Read more on this and other research on climate change adaptation by @rajatkochhar!
The UN is worried the world is not adapting fast enough to climate change. But what determines the pace of adaptation? In my #EconJMP, @RuoziSong and I study whether market competition aids or impedes farmer adaptation in India tinyurl.com/ybnmaybn
