Stock prices should respond only to unpredictable components of economic news ('innovations') in efficient markets. While innovations used in empirical investigations of the economic underpinnings of stock market risk should at least satisfy this basic requirement, this may not guarantee...

This study investigates multiple changes in persistence in the dividend–price and price–earnings ratio of the NASDAQ Composite Index. Recent time series methods that are capable of signalling and dating asset price bubbles are employed, in particular the method developed by Leybourne, Kim,...

Based on a method developed by Leybourne, Kim and Taylor (2007) for detecting multiple changes in persistence, we test for changes in persistence in the dividend-price ratio of the NASDAQ stocks. The results confirm the existence of the so-called Dotcom bubble around the last turn of the century...

A great deal of research has examined comovements between commercial real estate returns and macroeconomic variables in the US economy.

This paper examines the movements in the Marxian surplus-value rate using a Quantitative Marxist methodology. It examines the relationship between surplus-value and the degree of monopoly power in the UK economy using quarterly data and a proxy for aggregate concentration — the ratio of market...

Changes in the risk structure of stock returns may sometimes be very revealing. We examine economic variables that help explain principal components in UK stock returns, 01/1985 to 12/2001. The loading pattern on explanatory variables for the first component in a ‘bubble’ period is...

The stability of risk factors in the UK stock market is examined over time and across stock samples. Risk factors were identified by principal components analysis (PCA) on 22 small samples of stocks, over short time horizons. Stability across samples was investigated by a second-stage PCA, to...
