...AND RICHER...:

The US economy will officially become 3 per cent bigger in July as part of a shake-up that will see government statistics take into account 21st century components such as film royalties and spending on research and development. [...]

The changes will affect everything from the measured GDP of different US states to the stability of the inflation measure targeted by the Federal Reserve. They will force economists to revisit policy debates about everything from corporate profits to the causes of economic growth.

The revision, equivalent to adding a country as big as Belgium to the estimated size of the world economy, will make the US one of the first adopters of a new international standard for GDP accounting.

"We're capitalising research and development and also this category referred to as entertainment, literary and artistic originals, which would be things like motion picture originals, long-lasting television programmes, books and sound recordings," said Mr Moulton.

At present, R&D counts as a cost of doing business, so the final output of Apple iPads is included in GDP but the research done to create them is not. R&D will now count as an investment, adding a bit more than 2 per cent to the measured size of the economy.
