Option Pricing Kernels and the ICAPM

We estimate the parameters of pricing kernels that depend on both aggregate wealth and state variables that describe the investment opportunity set, using FTSE 100 and S&P 500 index option returns as the returns to be priced. The coefficients of the state variables are highly significant and remarkably consistent across specifications of the pricing kernel, and across the two markets. The results provide further evidence that, consistent with Merton's (1973) Intertemporal Capital Asset Pricing Model, state variables in addition to market risk are priced

What Drives Home Bias? Evidence from Fund Managers' Views

A survey of fund managers reveals home bias for these sophisticated investors in an unrestricted setting. Proximity, perceived informational advantage and higher expected returns are confirmed as accompanying factors. In addition, the home bias of equity managers is also related to institutional, informational and behavioral characteristics. The perceived informational advantage does not seem to be valid. Multivariate analyses indicate that home bias is mainly related to relative return optimism, non-fundamental information and peculiar behavior towards risk. We interpret these as characteristics of less than fully rational behavior. It is consistently found that this pattern does not apply to bond managers.Eine Befragung von Fondsmanagern offenbart die Heimatverzerrung (sog. Home Bias) dieser erfahrenen Investoren in unbegrenzten Rahmenbedingungen. Nähe, empfundene Informationsvorteile und höhere erwartete Renditen werden als Begleitumstände bestätigt. Zusätzlich ist der Home Bias von Aktienfondsmanagern mit institutionellen und informatorischen Gegebenheiten sowie mit bestimmten Verhaltensmustern verbunden. Der empfundene Informationsvorteil scheint sich jedoch nicht zu bewahrheiten. Multivariate Analysen zeigen, dass der Home Bias hauptsächlich mit relativem Renditeoptimismus, der Nutzung nicht-fundamentaler Informationen und besonderem Risikoverhalten verbunden ist. Wir interpretieren diese Eigenschaften als unvollkommen rationales Verhalten. Konsistent zeigt sich, dass dieses Muster nicht für Rentenfondsmanager gilt

Learning from your investors: can the geographical composition of institutional investors affect the chance of success in international M&A deals?

We produce new evidence on whether management which is keen to make foreign acquisitions can benefit from consultation with information-intensive institutional investors who have expertise in the target foreign markets. This research suggests that, in such instances, management should recognise the benefit of effective two-way communication before embarking on such costly strategies. Consistent with theoretical literature, we propose that this can be explained by the fact that complex valuation information is dispersed among many economic agents and management may only have limited access to such data. This research shows that the likelihood of both cross-border deal completion and medium-term cross-border deal success through time depends upon management learning from and getting the support of key institutional investors with regional (foreign) expertise. The theoretical information economics model presented by Dye and Sridhar in 2002 states that the information flow between management and capital markets should be viewed as two way. This study offers empirical evidence in support of their theory. This study offers insights into the positive effect of establishing a proactive investor relations programme for the recruitment of dedicated foreign institutional investors before embarking on cross-border M&A. The results indicate that management should closely monitor the share register and identify those investors who are transient and those who are, in contrast, dedicated. Attention then needs to be directed to establishing effective communication with the dedicated investors with regional expertise

Analogy making and the structure of implied volatility skew

An analogy based option pricing model is put forward. If option prices are determined in accordance with the analogy model, and the Black Scholes model is used to back-out implied volatility, then the implied volatility skew arises, which flattens as time to expiry increases. The analogy based stochastic volatility and the analogy based jump diffusion models are also put forward. The analogy based stochastic volatility model generates the skew even when there is no correlation between the stock price and volatility processes, whereas, the analogy based jump diffusion model does not require asymmetric jumps for generating the skew

Closing a mental account: the realization effect for gains and losses

How do risk attitudes change after experiencing gains or losses? For the case of losses, Imas (Am Econ Rev 106:2086–2109, 2016) shows that subsequent risk-taking behavior depends on whether these losses have been realized or not. After a realized loss, individuals’ risk-taking decreases, whereas it increases after an unrealized (paper) loss. He refers to this asymmetry as the realization effect. In this study, we derive theoretical predictions for risk-taking after paper and realized gains, and for investment opportunities with different skewness. We experimentally test these predictions and, at the same time, replicate Imas’ original study. Independent of a prior gain or loss, we show that subsequent risk-taking is higher when outcomes remain unrealized. However, we find no evidence of a realization effect for non-positively skewed lotteries. While the first result suggests that the effect is more general, the second result reveals its boundary conditions

Institutional investors and corporate governance

We provide a comprehensive overview of the role of institutional investors in corporate governance with three main components. First, we establish new stylized facts documenting the evolution and importance of institutional ownership. Second, we provide a detailed characterization of key aspects of the legal and regulatory setting within which institutional investors govern portfolio firms. Third, we synthesize the evolving response of the recent theoretical and empirical academic literature in finance to the emergence of institutional investors in corporate governance. We highlight how the defining aspect of institutional investors – the fact that they are financial intermediaries – differentiates them in their governance role from standard principal blockholders. Further, not all institutional investors are identical, and we pay close attention to heterogeneity amongst institutional investors as blockholders
