This paper uses a novel numerical optimization technique – robust optimization – that is well suited to solving the asset-liability management (ALM) problem for pension schemes. It requires the estimation of fewer stochastic parameters, reduces estimation risk and adopts a prudent approach...

Although tax relief on pensions is a controversial area of government expenditure, this is the first study of the tax effects for a real world defined benefit pension scheme. First, we estimate the tax and national insurance contribution (NIC) effects of the scheme's change from final salary to...

This paper contributes to the literature on cryptocurrencies by examining the performance of naïve (1/N) and optimal (Markowitz) diversification in a portfolio of four popular cryptocurrencies. We employ weekly data with weekly rebalancing and show there is very little to select between naïve...

This study investigates the impact of the choice of optimization technique when constructing Socially Responsible Investment (SRI) portfolios. Corporate Social Performance (CSP) scores are price sensitive information that is subject to considerable estimation risk. Therefore, uncertainty in the...

Tourism has a considerable economic effect on the host country; and setting the proportions of different types of tourist is an important dimension of host country tourism policy. We investigate three rival portfolio models that have been used to set policy targets for the proportions of...

The redesign of defined benefit pension schemes usually results in a substantial redistribution of wealth between age cohorts of members, pensioners, and the sponsor. This is the first study to quantify the redistributive effects of a rule change by a real world scheme (the Universities...
