Notes on older working papers
My research project on switching costs has led to
Small Switching Costs Lead to Lower Prices ,
published in the Journal of Marketing Research.
I am currently working on a more general framework (see WP above).
The paper Multimarket Contact Under Imperfect Observability, With an Application to Umbrella Branding (1998)
turned into Optimal Brand Umbrella Size (2007),
then into Umbrella Branding with Imperfect Observability and Moral Hazard , published in IJIO.
Football, Sailing, and R&D: Dynamic Competition with Strategic Choice of Variance and Co-Variance.
This paper, winner of the longest-title award, was turned into two papers: R&D Competition When Firms Choose Variance ,
published in JEMS;
and Increasing Dominance With No Efficiency Effect , published in JET.
See the publications page for details.
A follow-up to these papers is Go for Broke or Play it Safe? Dynamic Competition with Choice of Variance , published in RJE.
Entry Mistakes , CEPR Working Paper No. 1729, was published in EER under the title Simultaneous Entry and Welfare . I liked the old title better :(
R&D Alliances as Non-cooperative Supergames , CEPR Working Paper No. 1439, was published in IJIO as R and D Cooperation and Product Market Competition .
Learning to Compete and Vice-versa , Boston University's ISP Working Paper No. 39 (1992), was published in Econometrica as The Learning Curve, Market Dominance, and Predatory Pricing .
