Ernst Berndt and Zvi Griliches SBR-9511550 This proposal will continue ongoing research into the incorporation of technical change into price indexes. This is an important practical issue since the failure to account for changing quality is thought to be the largest source of bias in aggregate price indexes. And price indexes are used for such important tasks as the adjustment of social security payments to offset inflation, the implementation of cost-of-living clauses in union labor contracts, and the setting of monetary policy. The key problem in accounting for changes in quality is the determination of pre-introduction reservation prices for new goods. The proposal reviews a number of ways of doing this. These include using hedonic regressions, comparing branded and generic good prices, and estimating differentiated demand models. The P.I.s will implement these various approaches using data on pharmaceutical products and personal computers. In addition, they will seek out other data sources, such as scanner data.

Ernst Berndt和Zvi Griliches SBR-9511550 这项建议将继续进行目前关于将技术变化纳入价格指数的研究。 这是一个重要的实际问题，因为未能考虑到质量的变化被认为是总价格指数偏差的最大来源。物价指数被用于调整社会保障金以抵消通货膨胀、执行工会劳动合同中的生活费用条款以及制定货币政策等重要任务。 对质量变化进行会计核算的关键问题是确定新产品推出前的保留价格。 该提案审查了这样做的一些方法。 这些方法包括使用特征回归，比较品牌和一般商品的价格，以及估计差异化的需求模型。 PI将使用药品和个人电脑上的数据来实现这些不同的方法。 此外，他们还将寻找其他数据源，如扫描仪数据。
