Collusive Market Structure Under Learning-By-Doing and Increasing Returns

Learning by doing.

You have roughly 40 contact hours in a typical course. If all you do in them is lecture, you might as well just hand out your notes and let the students find something more productive to do with all that time. The only way a skill is developed—skiing, cooking, writing, critical thinking, or solving thermodynamics problems—is practice: trying something, seeing how well or poorly it works, reflec...

Learning by Doing

This chapter reviews the theoretical and empirical literature on learning by doing. Many of the distinctive theoretical implications of learning by doing have been derived under the assumption that the cost-quantity relationships observed in numerous empirical studies are largely the result of passive learning, and some further require that passive learning is unbounded. The empirical literatur...

Learning More by Doing Less

A principal must decide whether to implement each of two independent proposals (e.g., earmark requests, policy reforms, grant funding) of unknown quality. Each proposal is represented by an agent who advocates by producing evidence about quality. Although the principal prefers the most-informative evidence, agents strategically choose less-informative evidence to maximize the probability the pr...

Learning Graph Structure With Parametric and Non-Parametric Models

In discrete undirected graphical models, the conditional independence of the node labels Y is specified by the graph structure. We study the case where there is another input random vector X (e.g. observed features) such that the distribution P (Y | X) is determined by functions of X that characterize the (higher-order) interactions among the Y ’s. The main contribution is to learn the graph st...
