Estimating Aggregate Automotive Income Elasticities From the Population Income-Share Elasticity
提出一种仅用购买者平均收入和人口收入分布来估计产品收入弹性的新方法，并用汽车数据验证，结果直观合理。
The conventional approach to estimating the income responsiveness of a product's sales involves collecting data on sales as a function of income and product prices and then estimating a demand model. In many cases, it is very difficult to either collect the required data or reliably estimate the demand model. This article develops an alternative approach toward estimating these income-responsiveness parameters using only the average income of the product's buyers and the population income distribution. We illustrate our technique with automotive data and obtain fairly intuitive results.
