Shipping costs offer a potentially attractive measure of world real economic activity. However, the popular approach of removing a deterministic trend is not consistent with the observed behaviour of shipping costs and results in an unrealistic measure in data since 2015. This column compares alternative monthly measures based on shipping costs with direct estimates of world industrial production in terms of coherence with world GDP and usefulness for forecasting commodity prices, and concludes that industrial production is a much better measure. If shipping costs are to be used, the cyclical component should not be calculated using residuals from a linear trend.

Collaborative platforms have quickly penetrated several services sectors. Statistics on the development of the collaborative economy are essential for appropriate policy responses but there are few available. This column presents a simple methodology for estimating the economic size of the collaborative economy, which is also relevant for the platform economy.

The increasingly digital 21st century economy – with many zero-priced goods and services – is a challenging place for those striving to measure economic activity. This column reviews some of the main themes of the Bean Report on UK economic statistics. It suggests the exploitation of new data sources and the creation of a network of academics, private sector actors, and expert users. They would undertake research and development into the measurement of the economy and propose experimental statistics to capture the new phenomena.
