This paper reports on interesting changes in markdown pricing practices over time and differences in the pricing within a product line.

Fashion has become more important over time and appears to explain the greater seasonal variation in retail apparel prices in recent years. Differences in uncertainty also explains differences in the pricing of different types of men's dress shirts.
