1.1. The purpose of this paper is to present to the actuarial profession a stochastic investment model which can be used for simulations of “possible futures” extending for many years ahead. The ideas were first developed for the Maturity Guarantees Working Party (MGWP) whose report was published in 1980. The ideas were further developed in my own paper “Indexing Long Term Financial Contracts” (1981). However, these two papers restricted themselves to a consideration of ordinary shares and of inflation respectively, whereas in this paper I shall present what seems to me to be the minimum model that might be used to describe the total investments of a life office or pension fund.

This paper has two functions: first, in part 1, to present briefly the results of some recent investigations into the behaviour of a price index (in the United Kingdom) in order to gain some insight into the possible future progress of inflation; secondly, in parts 2–4, to present the arguments in favour of the linking to a price index of financial instruments, in particular government stocks, life assurance contracts and pension fund benefits. Part 1 is heavily statistical, and those who prefer the controversial material can go straight to part 2, noting only the conclusion to part 1, viz.: that it is not easy to forecast inflation over any lengthy period. Parts 2–4 are controversial, and I expect will still be topical when the paper is presented. I make no pretence to be impartial; I am convinced that widespread index-linking of long-term contracts would have a beneficial effect on the conduct of our financial affairs. It is up to those who disagree with me to put their case in the discussion; but I hope my supporters will express their views too.

This paper examines Yale Endowment model and proposes a modified investment model to achieve an investment objective of mainstream investors and to comply with Sharia principle. The proposed model utilizes Islamic CAPM to formulate the optimal asset allocation for Islamic pension fund’s portfolio. It will offer a strong investment strong which could be adopted by government to manage the Islamic pension fund and raise the awareness of society to see the great potential of Islamic pension fund in the future. Promoting an efficient and productive investment of pension-fund assets not only helps reaching Sustainable Development Goals (SDGs) by providing important sources of long-term finance for development, supporting financial inclusion and ensuring that poverty among the elderly is alleviated by a strong growth and resilience of income in retirement through pension systems that have broad coverage.

The present paper is a contribution to the building blocks of an investmentmodel within the framework of an integrated macroeconomic model of anIslamic economy. Investment behavior in the model is guided by an Islamicethicalvalue system and profit-sharing financial contracts. The typical firm’sinvestment decision is believed to emerge from a dynamic inter-temporalmaximization exercise within an infinite time horizon. The method of Calculusof Variations is applied to arrive at the optimal investment and employmentcriteria for the firm. The result is then incorporated into a macroeconomicmodel to study the behavior of key endogenous variables like national incomeand the rate of profit-share. Comparative statics exercised within a generalequilibrium framework reveal the potency of monetary policy but the neutralityof fiscal policy with respect to output and employment.IntroductionThe past decade has witnessed a tremendous outpouring of interest aswell as effort in the formalization of economic models based on profit-sharingfinancial arrangements as an Islamic alternative to the conventional interestbasedeconomic system. Several macroeconomic models for interest-freeeconomies have been proposed (Anwar 1987; Habibi 1987; Metwally 1981& 1983). The rigor of an integrated approach to such macroeconomic modelhgdepends on the rigor of the component models, namely, the consumption,investment, monetary, and fiscal relationships. Economists have writtenextensively on different aspects of consumer behavior in Islamic societies.Kahf (1978) and Khan (1984), among others, have contributed to the conceptualand analytical formulation of the consumption function under ...

1. It seems to be a common misconception outside the actuarial profession that those within that illustrious body are mysteriously able to peer into their crystal balls and come up with prophetic answers about the future progress of pension funds, insurance companies and other allied matters. The appearance of an actuarial report with its air of finality and disclosure of a definite surplus, deficiency, bonus declaration or whatever it may be, only endorses the impression that the actuary is reporting on the unique and unquestionable answer to the problem in hand.

Polish Pension Funds Investment - is There A Place For Real Property in A Portfolio?The pension fund investments should be characterised by a long term, low risk and profitability, which implicates the necessity of portfolio diversification. In general, pension funds having regular long-term contributions should develop the long-term policy and its effects would be responsible for the economic position of their future beneficiaries. The ways of capital allocation are also critical in terms of the entire economy, as a constant flow of financial resources provided by pension funds stimulates the activity of its recipients. The typical assets in a pension fund's portfolio in the developed economy are stocks, bonds and real property owing to low (negative) correlation between these assets and their diversified potential. The legal investment limits imposed on the Polish pension funds exclude direct investment in real property, which is responsible - in the authors' opinion - for the lower level of diversification and hinders the risk reduction. The authors analyze the Polish pension fund portfolios focusing on risk and return levels. The aim of the study is to find the answer to the important question about the results of hypothetically added real property to the portfolios of pension funds.

AbstractThis paper exploits a recent reform of private pension schemes in Italy to identify the impact on household saving of tax-favored retirement saving plans. The reform was part of the restructuring of the social security system and was aimed at rising private long-term saving by making pension funds more attractive and convenient. We control for unobserved saver heterogeneity and a central focus is on substitution across saving instruments. We find that the pension fund legislation had a strong effect on the allocation of saving and triggered substantial substitution of non-tax-favored non-retirement wealth for tax-favored pension funds. In contrast, we find that it had little, if any effect on household saving flows. Our findings also suggest that the provision of ‘closed’ pension funds might significantly affect the decision to invest in private retirement schemes.

The paper investigates the mid-term results of the tariff regulation influence on the amount of capital expenditures in Russian electricity distribution sector. We estimate panel data with the dynamic investment model using system GMM method. We showed that horizon of tariff regulation period is statistically significant and transition from the short-term regulation to the long-term tariff system had positive effect on the amount of regulated companies’ investments. At the same time we found that the design of long-term regulation applied in Russia in 2009–2013 (type of RAB-regulation and long-term indexation) was not statistically significant to the amount of investments. All over all, the amount of investments in electricity distribution networks has similar to European peers explanatory factors. The obtained results are important to the further improvement of regulation in power energy and can be applied in district heating as well.

Abstract Smoking was one of the biggest preventable killers of the 20th century, and it continues to cause the death of millions across the globe. The rapid growth of the e-cigarette market in the last 10 years and the claims that it is a safer form of smoking, and can help with smoking cessation, have led to questions being raised on their possible impact to society, the health of the population and the insurance industry. Recent media attention around the possible health implications of e-cigarette use has also ensured that this topic remains in the public eye. The e-cigarette working party was initiated by the Institute and Faculty of Actuaries’ Health and Care Research Sub-Committee in July 2016, with the primary objective of understanding the impact of e-cigarettes on life and health insurance. In this paper, we have looked at all areas of e-cigarette usage and how it relates to insurance in the UK market. In particular, we have covered the potential risks and benefits of switching to e-cigarettes, the results of studies that have been published, the potential impact on underwriting and claims processes and the potential impact on pricing (based on what modelling is possible with the data available). Research in this area is still in its infancy and data are not yet mature, which makes predicting the long-term impact of e-cigarette smoking extremely challenging, for example, there are no studies that directly measure the mortality or morbidity impact of long-term e-cigarette use and so we have had to consider studies that consider more immediate health impacts or look more simply at the constituents of the output of an e-cigarette and compare them to that of a cigarette. The data issue is further compounded by the findings of studies and the advice of national health authorities often being conflicting. For example, while National Health Service England has publicly stated that it supports the growth of e-cigarette usage as an aid to reduce traditional smoking behaviour, the US Food and Drug Administration has been much more vocal in highlighting the perceived dangers of this new form of smoking. Users’ behaviour also adds complexity, as dual use (using both e-cigarettes and cigarettes) is seen in a high percentage of users and relapse rates back to cigarette smoking are currently unknown. Having talked to a number of experts in the field, we have discovered that there is certainly not a common view on risk. We have heard from experts who have significant concerns but also to experts who do believe that e-cigarettes are far safer than tobacco. We have purposefully considered conflicting evidence and have consulted with various parties so we can present differing points of view, thereby ensuring a balanced, unbiased and fair picture of our findings is presented. The evidence we have reviewed does suggest that e-cigarettes are a safer alternative to traditional smoking, but not as safe as non-smoking. There are no large, peer-reviewed, long-term studies yet available to understand the true impact of a switch to e-cigarette use, so currently we are unable to say where on the risk spectrum between cigarette smoking and life-time non-smoking it lies. We do not yet understand if the benefits seen in the studies completed so far will reduce the risk in the long term or whether other health risks will come to light following more prolonged use and study. This, coupled with concerns with the high proportion of dual use of cigarettes and e-cigarettes, relapse rates and the recent growth in medical problems linked with e-cigarette use, means that we need to wait for experience to emerge fully before firm conclusions can be drawn. Although we have presented a view, it is vitally important that our industry continues to monitor developments in this area and fully considers what next steps and future actions may be required to ensure our position reflects the potential benefits and risks that e-cigarette use may bring. We feel that the time is right for a body such as the IFoA to analyse the feasibility of collecting the necessary data through the Continuous Mortality Investigation that would allow us to better analyse the experience that is emerging.
