There is a long standing interest in the question of whether or not low income households face the same prices as households with higher incomes. If low income households face lower or higher prices than high income households, then income inequality may be greater or lesser than is suggested by...

For most indexes in the Consumer Price Index (CPI), the Bureau of Labor Statistics (BLS) uses a form of the matched-model approach. It has long been recognized that the matched-model method can underestimate quality improvement, and therefore overestimate price inflation, for products exhibiting...

We describe a test, based on the correlation integral, for the independence of a variable and a vector that can be used with serially dependent data. Monte Carlo simulations suggest that the test has good power to detect dependence in several models, performing nearly as well or better than the...

We measure the change in household spending caused by receipt of the economic stimulus payments of 2008, using questions added to the Consumer Expenditure Survey and variation from the randomized timing of disbursement. Households spent 12-30 percent (depending on specification) of their...

The Consumer Price Index (CPI) has often been the subject of controversy. Historically, the most prominent critics have argued that the CPI overstates changes in the cost of living. Recently, however, some in the investment community and business media have argued that the CPI is an...

In this paper we provide new and detailed evidence on the impact on the U.S. CPI of the appearance and growth of new types of product outlets. Using actual CPI microdata for 2002-2007, we find that the changing mix of outlets had a statistically significantly negative impact on average prices in...

While many studies find that the tax-price elasticity of giving exceeds unity, several recent studies find the contrary. This is important because it can be shown that if the elasticity exceeds one, then allowing taxpayers to deduct charitable giving from their taxable income is efficient in the...

In contrast to earlier studies, recent research finds that charitable contributions are tax-price inelastic, suggesting that the itemized deduction for contributions loses more tax revenue than it increases in contributions. The estimates from parametric methods are similar to those in earlier...
