Standard macroeconomic models suggest that the ‘great ratios’ of consumption to output and investment to output should be stationary. The joint behaviour of consumption, investment and output can then be used to measure trend output. We adopt this approach for the USA and UK, and find...

Standard macroeconomic models suggest that the 'great ratios' of consumption to output and investment to output should be stable functions of structural parameters. We examine whether the ratios are stationary for the US and UK, allowing for structural breaks that could reflect time-varying...
