WP 2006-11 May 2006 Working Paper Department of Applied Economics and Management Cornell University, Ithaca, New York 14853-7801 USA Bubbles or Convenience Yields? A Theoretical Explanation with Evidence from Technology Company Equity Carve-Outs Vicki Bogan It is the Policy of Cornell University actively to support equality of educational and employment opportunity. No person shall be denied admission to any educational program or activity or be denied employment on the basis of any legally prohibited discrimination involving, but not limited to, such factors as race, color, creed, religion, national or ethnic origin, sex, age or handicap. The University is committed to the maintenance of affirmative action programs which will assure the continuation of such equality of opportunity. Bubbles or Convenience Yields? A Theoretical Explanation with Evidence from Technology Company Equity Carve-Outs Vicki Bogan¤ This Version: March 2006 Abstract This paper offers an alternative explanation for what is typically referred to as an asset pricing bubble. We develop a model that formalizes the Cochrane (2002) convenience yield theory of technology company stocks to explain why a rational agent would buy an “overpriced” security. Agents have a desire to trade but short-sale restrictions and other frictions limit their trading strategies and enable prices of two similar securities to be different. Thus, divergent prices for similar securities can be sustained in a rational expectations equilibrium. The paper also provides empirical support for the model using a sample of 1996 - 2000 equity carve-outs.

For Continuous-Time Models in Economics and Finance, We Want To
Chapter 3 — Arbitrage and Pricing Arbitrage is a very important and simple concept used in finance to pin down possible prices. It is simple to use because the existence or absence of arbitrage does not rely upon anyone’s subjective probability beliefs, apart from agreement on what is possible and impossible. Nor does it rely upon anyone’s utility, apart from the assumption that all prefer more money to less. An arbitrage is a portfolio of assets with a zero or negative current costs and an outcome guaranteed to be nonnegative. At least one of the possible outcomes or the cost must differ from zero otherwise arbitrage would include the trivial “nothing” portfolio that made no purchase and received nothing. It is natural to preclude the existence of arbitrage opportunities in Finance as its existence would mean that arbitrarily large amounts of money could be extracted from the set of assets either now or later. Any investor would always wish to add an arbitrage to his portfolio as it would never increase the cost and never reduce any payoff. The desire of every investor to purchase any arbitrage should increase its cost until it ceases to be an arbitrage. A concept closely related to arbitrage is dominance. One random variable dominates another if it is never smaller and can be larger. If the payoffs on one asset or portfolio dominate some other another and the first costs no more, there is an arbitrage consisting of buying the dominating asset and selling the dominated one. Perhaps the first lesson learned is Finance is how to compute a present value. -

Stocks as Money: Convenience Yield and the Tech-Stock Bubble John H. Cochrane NBER Working Paper No. 8987 June 2002 JEL No. G1 ABSTRACT What caused the rise and fall of tech stocks? I argue that a mechanism much like the transactions demand for money drove many stock prices above the ``fundamental value'' they would have had in a frictionless market. I start with the Palm/3Com microcosm and then look at tech stocks in general. High prices are associated with high volume, high volatility, low supply of shares, wide dispersion of opinion, and restrictions on long-term short selling. I review competing theories, and only the convenience yield view makes all these connections.
