We test and confirm the hypothesis that individual investors are net buyers of attention-grabbing stocks, e.g., stocks in the news, stocks experiencing high abnormal trading volume, and stocks with extreme one-day returns. Attention-driven buying results from the difficulty that investors have searching the thousands of stocks they can potentially buy.(More)
We investigate asset-allocation strategies open to members of defined-contribution pension plans with a model that incorporates asset, salary (labour-income) and interest-rate risk. We propose a novel form of terminal utility function, incorporating habit formation, that uses the member's final salary as a numeraire. The paper discusses various properties(More)
In this article, we consider the evolution of the postage -60 mortality curve in the United Kingdom and its impact on the pricing of the risk associated with aggregate mortality improvements over time: so-called longevity risk. We introduce a two-factor stochastic model for the development of this curve through time. The first factor affects mortality-rate(More)
It is now widely accepted that stochastic mortality – the risk that aggregate mortality might differ from that anticipated – is an important risk factor in both life insurance and pensions. As such it affects how fair values, premium rates, and risk reserves are calculated. This paper makes use of the similarities between the force of mortality and interest(More)
>IJH=?J Using a data set on more than 300 UK pension funds' asset holdings, this paper provides a systematic investigation of the performance of managed portfolios across multiple asset classes. We ¯nd evidence of slow mean reversion in the funds' portfolio weights towards a common, time-varying strategic asset allocation. We also ¯nd surprisingly little(More)
We compare quantitatively eight stochastic models explaining improvements in mortality rates in England and Wales and in the United States. On the basis of the Bayes Information Criterion (BIC), we find that, for higher ages, an extension of the Cairns-Blake-Dowd (CBD) model that incorporates a cohort effect fits the England and Wales males data best, while(More)
This paper uses a large sample containing the complete return histories of 2300 UK open-ended mutual funds over a 23-year period to measure fund performance. We find some evidence of underperformance on a risk-adjusted basis by the average fund manager, persistence of performance and the existence of a substantial survivor bias. Similar findings have been(More)
The UK is one of the few countries in Europe that is not facing a serious pensions crisis. The reasons for this are straightforward: state pensions are among the lowest in Europe, the UK has a long-standing funded private pension sector, its population is ageing less rapidly than elsewhere in Europe and its governments have, since the beginning of the(More)
We consider the choices available to a defined contribution (DC) pension plan member at the time of retirement for conversion of his pension fund into a stream of retirement income. In particular, we compare the purchase at retirement age of a conventional life annuity (i.e., a bond-based investment) with distribution programmes involving differing(More)
