In graduate labor economics II, students have already master the uses the five econometric techniques, and are familiar with the issues that may jeopardize our causal inference, and the pros and cons of potential solutions. In this class we will try to extend our reach with one more set of tools: experimental methods. Armed with these weapons, we will march into the unconventional world of economics, and see how far we can go. Our purpose is to see how to use economics to understand the real world, ie: how people react to incentives. We will explore many exotic topics, such as crime, influenza, media influence, time discounting, reference points, other than traditional labor economics.
