高科技产品的一个显著特点是其按质量调整的价格迅速下降。经验研究表明，QAP的下降率通常不是一个常数; QAP在产品的早期阶段迅速下降，然后下降率逐渐减少。研究还表明，QAP与产品推出速度呈正相关：新产品推出得越快，QAP下降的速度就越快。本文提出了一个产品创新的动态模型，与这些经验教训相一致。
A striking characteristic of high-tech products is the rapid decrease of their quality-adjusted prices. Empirical studies show that the rate of decrease of QAPs is typically not constant over time; QAPs decrease rapidly at early stages of the product and then the rate of decrease tapers off. Studies also suggest that the QAP is positively correlated with the rate of product introductions: The faster new products are introduced, the faster is the rate of decrease in their QAPs. This paper presents a dynamic model of product innovations consistent with these empirical regularities.
