Retail pricing and clearance sales: the multiple product case

This paper deals with the phenomenon of clearance sales of fashion type goods which have an intertemporal aspect similar to durable goods. Using the Van Praag and Bode (1992) model, the case of clearance sales in a store selling more than one commodity is analyzed. Conditions and rules of thumb are shown in which it is optimal to increase the price of one product while decreasing the price of another. A linear demand model and a numerical example are presented, showing that the price of one product decreases while the price of the other product may increase or decrease in different periods.     

CONCEPTS OF FAIRNESS IN THE GLOBAL TRADING SYSTEM

Abstract.  We first discuss why fairness is a condition of the agreements among governments that form the global trading system. We then suggest that fairness can best be considered within the framework of two concepts: equality of opportunity and distributive equity. We thereafter discuss what these mean as applied to market access and its supporting rules as well as to dispute settlement and trade remedy measures. Finally, we make some comments about fairness in the Doha Development Round.     

Volatility Estimation with Price Quanta

Volatility estimators based on high, low, opening and closing prices have been developed, and perform well on simulated data, but on real data they frequently give lower values for volatility than the simple open–close estimator. This may be due to the fact that for real data, the maximum (or minimum) price is often at the beginning or end of the day. While this could not happen if the observed process was log Brownian, it could happen if the observed process were log Brownian, but observed only to the nearest penny. We develop the theory of such approximations to derive the corrected versions of the basic estimators.     

Chambers as Educator and Mentor

Adopting a personal tone, this article explores Ray Chambers' impact on accounting and management education and through that his impact on accounting thought and practice. As mentor and colleague for over a quarter of a century, Chambers left many wonderful impressions, some of which are described here. The article describes some of the influences on the innovations and approaches of a great teacher. Familial and early working life experiences are shown to have greatly influenced his views on accounting, finance and management, and hence his innovations in accounting and management education at both the Sydney Technical College and the University of Sydney. His research, writings and teachings continually stressed the need to apply common sense to common experience. The article concludes by noting Chambers' perennial pursuit of seeking evidence to test his ideal solution to eradicate the follies and infelicities that plagued then (and still plague today) accounting thought and practice. Chambers regarded having such an ideal as the essence of being a researcher.
