Import price statistics may not be a reliable indicator of welfare gains. They must adequately reflect the fact that consumers value variety, and that consumer tastes and product quality change over time. This column evaluates existing findings, and introduces new results for the four largest EU economies – including evidence of higher consumer welfare gains than suggested by official import prices for the period from 1995 to 2012.

As a measure of economic activity, GDP is imperfect, but no more so than any single indicator of the whole economy. Yet public policy debate about the economy is often focused on GDP growth to the exclusion of other important considerations. This Vox Talk argues the case for a ‘dashboard’ of alternative indicators that, in addition to measuring economic activity, could also capture social welfare, sustainability and the benefits of innovation.

Criticism of Gross Domestic Product (GDP) as an indicator of the health of the economy has grown in recent years, in part because of a new focus on measures of subjective well-being or ‘happiness’. This column argues that the debate needs to distinguish between the different purposes of measurement: economic activity, social welfare, and sustainability are distinct concepts and cannot be captured by a single indicator. There are good arguments for paying less attention to GDP and more to indicators of welfare and sustainability, but it would be a mistake to adjust or replace GDP.
