Using a panel of UK firms spanning three decades, we provide estimates of the long-run elasticity of substitution between capital and other factors of production, the (negative of the) elasticity of capital and investment with respect to the user cost. The parameter is estimated using 'time...

The methodology used in papers by Darby and Ireland and Caporale and Williams is examined, to see whether it continues to explain UK consumption behaviour. First, Muellbauer and Murphy's proxy for financial liberalisation (FLIB) is updated. Then a forward-looking consumption model is...

Theory tells us that output, the capital stock and the user cost of capital are related. From the capital accumulation identity, it also follows that the capital stock and investment have a long-run proportional relationship. The dynamic structure thus implies a multi-cointegrating framework, in...

Conventional wisdom has it that Tobin’s Q cannot help explain aggregate investment. This is puzzling, as recent evidence suggests the closely related user cost approach can do so. We do not attempt to explain this puzzle. Instead, we take an entirely different approach, not using the...

In recent years there has been increasing interest in forecasting methods that utilise large data sets, driven partly by the recognition that policymaking institutions need to process large quantities of information. Factor analysis is a popular way of doing this. Forecast combination is...

From neoclassical theory output, capital stock and the user cost are cointegrated; capital and investment also (multi)cointegrate through the capital accumulation identity. An investment equation is estimated on UK data using a new capital stock series and a long series for the weighted cost of...
