Course Materials

0.         The two principles: Revelation and Revenue Equivalence

Main ideas: The revelation principle forms the cornerstone for the theory of contracts and incentives in organizations. This topic reviews the revelation principle, the principal families of contract theory models, and the mechanism design paradigm.

Readings:         

Chapters 8.E and 13 of Microeconomic Theory by Andreu Mas-Colell, Michael Whinston, and Jerry Green. Oxford University Press, 1995.

Why Every Economist Should Learn Some Auction Theory

“...Plus Shipping and Handling: Revenue (Non)Equivalence in Field Experiments on eBay”

John Morgan and Tanjim Hossain, Advances in Economic Analysis & Policy, 2006, Vol. 6: No. 2, Article 3.

1.         Search

Main idea: This topic surveys a variety of consumer search models. The two principles play an important role in generalizing some of the findings. These models are cornerstones for modeling price competition.

Reading:            

"Information, Search, and Price Dispersion,"
Michael R. Baye, John Morgan, and Patrick Scholten in Handbook of Economics and Information Systems (T. Hendershott, ed.), Elsevier Press, Amsterdam, 2006

Michael R. Baye, John Morgan, and Patrick Scholten, Journal of Industrial Economics, December 2004; 52(4): 463-96.

2.         Contests

Main idea: This topic surveys the contest/all-pay auction literature. Again, the two principles prove extremely useful. This literature is the cornerstone for modeling political competition, patent and R&D races, and so on.

Reading:

3.         Platform Competition

Main idea: This topic highlights the emerging literarture on platform competition and two-sided markets. The revenue equivalence principle sees a little sue here as well. These are the leading modeling approaches for markets that are increasingly prominent.
