My Papers 

I am curious about many aspects of economic theory. In my finite time, I have so far written on game theory and various aspects of information economics such as search, matching, and learning. A couple papers are currently well cited now, and others will one day be thus. :) I think that when doing theory, one must allow oneself a longer impact time horizon than for more applied work.
