The U.S. CPI is based on the Laspeyres price index, an index type that has an upward "substitution bias." Thus, the CPI tends to overstate increases in the cost of living. To address this bias, the Advisory Commission to Study the Consumer Price Index recommended adopting for the CPI a...

This study uses an incentive-compatible experimental online supermarket to assess whether prior environmentally-friendly behaviour outside the store, and whether carbon taxes motivate sustainable consumption. Previous research suggests that past decisions may influence current decisions, for...

We explore the extent to which LIS-data can be used to shed light on the presence of women in the top of the income distribution. We show developments of the share of women in top groups (P90-100 and P99-100) of the labour income distribution for 28 countries and, when possible, compare to...

The article describes the revenue estimates of incremental versus fundamental reform options for taxation of individual wealth, and explains how tax avoidance assumptions underlie the larger estimates for fundamental reform

Charitable bequests are a major source of income for charities but surprisingly little is known about them. The aim of this paper is to propose a multi-stage framework for analysing the bequest decision and to examine the evidence for Great Britain provided by new data on estates. The novelty of...

Using a model where households can save in either a safe asset or in an illiquid, tax-advantaged pension, we assess the extent to which those who recently reached the state pension age in the UK have saved optimally for retirement. The policy environment specified closely matches that prevailing...

The Hamilton method for estimating CPI bias is simple, intuitive, and has been widely adopted. We show that the method confiates CPI bias with variation in cost-of-living across income levels. Assuming a single price index across the income distribution is inconsistent with the downward sloping...

A major difficulty faced by researchers who want to study the consumption and savings behavior of households is the lack of reliable panel data on household expenditures. One possibility is to use surveys that follow the same households over time, but such data are rare and they typically have...
