Double Chain Ladder

Author(s):

María Miranda

 et al.

This paper presents an extension to the model for forecasting outstanding claims liabilities, formulated by Verrall et al. (2010). The resulting model is closely related to the chain ladder method. So close in fact, it is possible to produce exactly the same results, if a particular choice is made about the way the estimates are obtained. This raises the question of why a new method is necessary. This research puts forward several answers.

Optimal customer selection for cross-selling of financial services products

Author(s):

Jens Nielsen

 et al.

In this research a new methodology for optimal customer selection in cross-selling of financial services products, such as mortgage loans and non life insurance contracts, is presented. Financial services companies tend to possess significant databases and a long relationship with each customer. In this situation the challenge becomes to use the database in general and specific knowledge of the individual target to estimate the probability of a cross-sale, the cost of a cross-sale attempt, the average discounted future profit and the uncertainty of the profit of the entire cross-sale attempt for that individual. Once reliable estimates for the stochastics of the cross-sale process have been established, one can optimise the cross-sale profit according to a variety of criteria including return and risk. In this paper, we first consider the simple question of optimising the average profit, but we also consider one version of adjusting for risk when optimising cross-sale profits. Our extensive case study is taken from non-life insurance, where our sales probability model is provided to us by the company that also provided us with the data.

Investigating the broken-heart effect

Author(s):

Jaap Spreeuw

 et al.

The traditional assumption made in life insurance about the independence of the remaining lifetimes of a couple has come under greater scrutiny recently.

In this paper, the researchers postulate that dependence between coupled lifetimes is of a short-term type. Evidence is found that mortality rates increase after the death of a partner and, in addition, that this phenomenon diminishes over time.

In this paper, we study stationary states and mean first passage times (MFPT) of four well-known mean reverting processes: the square root process of Feller, the Ahn-Gao model, the GARCH diffusion model and the stochastic Verhulst process.

Modeling housing market fundamentals: empirical evidence of extreme market conditions

Author(s):

Simon Steveson

Topic:
Finance
Industry:
Real Estate

This article examines the issues encountered in the modeling of market fundamentals during a period of extreme price behavior. The study analyzes the price behavior of the residential property market in Ireland using a number of alternative methodological approaches in the estimation of fundamental market value. Limitations in conventional models such as an inverted demand model are highlighted, in particular, with regard to diagnostic concerns and the static nature of the model. The use of an error correction framework provides more consistent and robust findings. The analysis does appear to indicate that a substantial premium over fundamental values developed in the Irish market during the late 1990s, reaching a peak in 1999 and 2000. However, in recent years, prices have largely been in line with fundamentals.

Behavioural finance: quo vadis?

Author(s):

Gulnur Muradoglu

Topic:
Finance

Behavioural finance endeavours to bridge the gap between neoclassical finance and cognitive psychology. Now an established field, behavioural finance looks at the investors' decision making formula as well as at their behaviour, which in turn sheds light on the observed departures from the traditional finance theory. The paper provides an overarching view of the behavioural finance area.
