Pet Peeves: Trademark Law and the Consumer Enjoyment of Brand Pet Parodies

Consumers appear to appreciate trademark parodies, particularly those that are related to pets. In contrast, some trademark owners object to such parodies. However, as this article demonstrates, trademark law generally allows the sale of parody products unless these products copy the targeted trademarks too closely.     

Information and Volatility: The No-Arbitrage Martingale Approach to Timing and Resolution Irrelevancy

The no-arbitrage martingale analysis is used to study the effect on asset prices of changes in the rate of information flow. The analysis is first used to develop some simple tools for asset pricing in a continuous-time setting. These tools are then applied to determine the effect of information on prices and price volatility, to extend Samuelson's theorem on prices fluctuating randomly, and to study the impact on prices of the resolution of uncertainty. The conditions under which uncertainty resolution is irrelevant for asset pricing are shown to be similar to those which support the MM irrelevance theorems.

The U.S. Treasury Buyback Auctions: The Cost of Retiring Illiquid Bonds

We study an important recent series of buyback auctions conducted by the U.S. Treasury in retiring $67.5 billion of its illiquid off‐the‐run debt. The Treasury was successful in buying back large amounts of illiquid debt while suffering only a small market‐impact cost. The Treasury included the most‐illiquid bonds more frequently in the auctions, but tended to buy back the least‐illiquid of these bonds. Although the Treasury had the option to cherry pick from among the bonds offered, we find that the Treasury was actually penalized for being spread too thinly in the buybacks.     

Estimating Current Cost Depreciation Expense Using Numerical Analysis and the STAPOL Technique: A Pedagogic Exposition

Current cost accounting (CCA) recommendations have led to complex measurement problems. This paper aims to provoke discussion of the use of numerical analysis and the STAPOL technique as a method for measuring current cost depreciation expense. The measurement method analysed has a scientific foundation, is simple to apply, and yields accurate results. With slight modification, the method analysed is also applicable to other areas of CCA characterized by intractable measurement problems. Unlike other papers which have used differential calculus to analyse the use of numerical analysis in accounting, the exposition in this paper depends on only a rudimentary knowledge of algebra.     

ARE SURVEYS OF EXPERTS UNBIASED? EVIDENCE FROM COLLEGE FOOTBALL RANKINGS

Policymakers are frequently interested in soliciting unbiased information regarding alternative policies, and expert surveys can be influential. As ranking policies is an often subjective process, there is always the concern of bias, both intentional and not. Expert bias is difficult to discern in the policy world, but surveys of expert opinion are compiled and “tested” for accuracy weekly in college football, allowing for hypothesis testing. Although previous research has used college football rankings to determine the ability of surveys to incorporate relevant information, this article examines the Associated Press and American Football Coaches' Association rankings for evidence of systematic bias. Specifically, more than 1,300 games from the 2003 to 2008 regular seasons are tested for factors that are systematically correlated with upsets. Both polls predict the winner nearly 80% of the time, and although there is evidence of systematic conference bias, correcting the rankings would only improve the accuracy of the polls by about 1%. There is no evidence of a bias favoring “big market” teams, nor teams that have strong journalism programs or are from the East Coast. (JEL D4, L8)
