Fashion, Styling, and the Within-Season Decline in Automobile Prices
研究了1954至1989年间美国新车零售价格季节波动下降、二手车年贬值率减缓的现象，发现主要原因是车型大改成本上升导致改款频率降低，新车与旧款替代性增强，汽车逐渐脱离时尚属性。
Between 1954 and 1989 the seasonal variation in retail new car prices declined, while the annual percentage decline in used car prices lessened. To explain these long-term changes, this article suggests that a rise in the cost of a major model change has reduced the frequency of major model changes, changed the characteristics of new models, and resulted in smaller within-season price declines. New cars of adjacent model years have become closer substitutes as the importance of the annual model change has lessened. The American automobile has slowly become less of a fashion product because it has become increasingly costly to supply frequent styling changes. In contrast, the within-season price decline in women's apparel has increased over time as fashion has become more important. Reasons for the different price patterns are investigated.
