Sticky prices and behavioural indifference curves

John Komlos, 24 July 2014

Many quantities fail to respond smoothly to price changes. This column stresses that the ‘endowment effect’ – a well-known behavioural economics concept – implies kinks in indifference curves at the current consumption bundle price. Such kinks may account for the stickiness of prices, wages, and interest rates.

Piketty’s two laws

Ton van Schaik, 6 July 2014

Piketty’s book “Capital in the 21st century” has gained popularity with its finding of a growing gap between wage earners and capital owners. This column presents a test to the two main laws in Piketty’s book. The attractiveness of these two laws is in their simplicity, but so is their limitation. Piketty neglects investment replacement and depreciation.

Using happiness scales to inform policy: Strong words of caution

Timothy N. Bond, Kevin Lang, 4 July 2014

Self-reported measures of happiness are growing in popularity as alternatives to GDP. This column presents a novel statistical critique of the validity of comparing such measures across groups. Since monotonic transformations of individuals’ happiness levels can reverse average happiness rankings between countries, no meaningful comparison can be made without assumptions on the distribution of happiness.

Culture: Persistence and evolution

Francesco Giavazzi, Ivan Petkov, Fabio Schiantarelli, 16 June 2014

The persistence of cultural attitudes is an important determinant of the success of institutional reforms, and of the impact of immigration on a country’s culture. This column presents evidence from a study of European immigrants to the US. Some cultural traits – such as deep religious values – are highly persistent, whereas others – such as attitudes towards cooperation and redistribution – change more quickly. Many cultural attitudes evolve significantly between the second and fourth generations, and the persistence of different attitudes varies across countries of origin.

Why GDP just doesn’t add up

Diane Coyle, 9 June 2014

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.
