Sampling Strategies for Information Goods

Authors
Daniel Halbheer, Florian Stahl, and Donald Lehmann
Date
June 1, 2012
Format
Working Paper

This paper analyzes optimal decisions concerning the size of the sample and the price of the paid content for online publishers of digital information goods when sampling serves the dual purpose of disclosing content quality and generating advertising revenue. We show in a reduced-form model how the publisher?s optimal ratio of advertising revenue to sales revenue is linked to characteristics of both the content market and the advertising market.

Journal of Financial Economics

We consider the optimal design of mortgage-backed securities (MBS) in a dynamic setting in which a mortgage underwriter with limited liability can engage in costly hidden effort to screen borrowers and can sell loans to investors. We show that (i) the timing of payments to the underwriter is the key incentive mechanism, (ii) the maturity of the optimal contract can be short, and that (iii) bundling mortgages is efficient as it allows investors to learn about underwriter effort more quickly, an information enhancement effect.

The Journal of Finance

This paper studies the presence of hedge funds in the Chapter 11 process and their effects on bankruptcy outcomes.

Gurus and Oracles: The Marketing of Information

Authors

Date

Format
Book
Publisher
MIT Press

We live in an "Information Age" of overabundant data and lightning-fast transmission. Yet although information and knowledge represent key factors in most economic decisions, we often forget that data, information, and knowledge are products created and traded within the knowledge economy. In Gurus and Oracles, Miklos Sarvary describes the information industry—the far-flung universe of companies whose core business is to sell information to decision makers.

Capital Access Bonds: Contingent Capital with an Option to Convert

Authors
Patrick Bolton and Frederic Samama
Date
January 1, 2012
Format
Journal Article
Journal
Economic Policy

This paper argues that there is a Coasean Bargain available to banks, Long-term Investors, and Bank Regulators around a particular form of "Contingent Capital." By purchasing rights to issue equity in crisis events at a pre-specified price from Long-term Investors, banks can ensure that they will have sufficient regulatory capital available when they need it most: in a crisis. By selling these rights (effectively, a form of crisis insurance) long-term investors can monetize their counter-cyclical investments strategies in banks and, thus, obtain an adequate return as long-term investors.

The Real Effects of Financial Markets: The Impact of Prices on Takeovers

Format
Journal Article
Journal
Journal of Finance

This paper provides evidence of the real effects of financial markets. Using mutual fund redemptions as an instrument for price changes, we identify a strong effect of market prices on takeover activity (the "trigger effect"). An inter-quartile decrease in valuation leads to a 7 percentage point increase in acquisition likelihood, relative to a 6% unconditional takeover probability. Instrumentation addresses the fact that prices are endogenous and increase in anticipation of a takeover (the "anticipation effect").
