The abstract expressionists revolutionised the art world in the late 1940s, only to be displaced by the pop art revolution less than two decades later. This column uses auction price data to explore the life cycles of major painters from the two groups. The abstract expressionists were much older when they produced their peak value works, while the pop artists tended to be most productive in their twenties. The findings provide a systematic basis for dating these revolutions in art markets.

Many consumers buy multiple types of goods from a single location (or firm) to save on shopping costs, turning these goods into pricing complements. Using data from the UK, this column shows that the internalisation of these complementary effects by supermarkets greatly improves the competitiveness of grocery supply. It also argues that one-stop shoppers have a greater pro-competitive impact on supermarket pricing than multi-stop shoppers.

A key task for economists is predicting how markets will respond to complex changes in environment. This column discusses recent empirical developments that allow for a deeper understanding of such market dynamics. Game theory has informed conditional pricing models that take account of products marketed and their production costs. Likewise, dynamic models of productive efficiency allow for analyses of the role of market structure in inducing competitive efficiencies.

What happens to prices when a country joins a currency union, and do prices behave differently in a pegged exchange rate regime? This column sheds lights on these questions by using evidence from Latvia, whose currency was pegged to the euro before the country became a Eurozone member on 1 January 2014. The authors find that clothing retail prices in Latvia completely converged to those in other Eurozone countries.

Did Apple forgo potential revenue for years? Until recently, its iTunes music store employed uniform pricing. This column uses a willingness to pay survey to show how alternative pricing schemes could have raised more revenue. Non-uniform pricing might have raised revenues by as much as 28%, and Apple could have substantially increased its revenues without reducing consumers’ welfare.
