We analyse the post-issue operating performance of 304 venture-backed and 264 non-venture UK IPOs 1985-2000. IPOs exhibit a significant five-year, post-issue operational decline over the full sample period. However this is driven by a particularly poor performance by venture-backed and...

We employ the Barberis, Shleifer and Wurgler (2004) methodology to investigate the impact of changes to the FTSE 100 index on return comovement over the 1992-2002 period. For FTSE stock inclusions the average increase in the beta coefficient is 0.38 in univariate regressions for weekly returns...

This paper investigates whether prospect theory (PT) or a preference for lottery-like gains on stocks can explain the peculiarities of IPO returns in China. Chinese IPOs offer investors two potential lottery-like gains. One is potentially huge first day returns as Chinese issuers leave more...

This paper develops closed-form solutions for the finite integrals in the volatility, cubic and quartic contracts in Bakshi, Kapadia and Madan (2003) which avoid discretization errors and do not involve interpolation and extrapolation. It compares the accuracy of the closed-form approach with...

We propose and test a new misvaluation approach to mergers and acquisitions (Mamp;As) using a sample of 302 UK bidders and targets 1986-2002. Our model assumes that managers have insider information on book values while investors only have publicly available information. We find that bidders are...

This paper examines the effects of ex-ante misvaluation on merger activities in UK 1985-2002 using a sample of 302 bidders and targets. Adopting the methodology of M/B by Rhodes-Kropf, Robinson, and Viswananthan (2005), we decompose M/B into three components: firm-specific errors, sector-wide...

The nominee approach to equity crowdfunding pools all crowd investors into one (nominee) account where typically the platform acts as the legal owner but the crowd retains beneficial ownership. The platform plays an active digital corporate governance role that simultaneously enfranchises crowd...

The paper examines the relationship between both individual and institutional investor sentiment measures and the risk-neutral skewness (RNS) of seven stock index options comprising either growth or value stocks. It provides novel evidence that growth index option prices are affected by...

This paper assesses empirically two competing unemployment theories. It identifies one structural break in U.K. and German unemployment around 1980 that is more severe in both absolute and relative terms than that for the United States in 1973. This offers support for the structuralist theory. A...

This paper proposes an asymmetric Markov regime-switching (MS) GARCH model to estimate value-at-risk (VaR) for both long and short positions. This model improves on existing VaR methods by taking into account both regime change and skewness or leverage effects. The performance of our MS model...
