In the current auction-based electricity market, design of utility-scale renewable energy systems has traditionally been driven by levelised cost (LCoE). However, market is gradually moving towards a subsidy-free era, which will expose power plant owners to fluctuating prices electricity. This paper presents computational approach account for influence time-varying on airborne wind (AWE) system...

Economists often take it for granted that any finite utility value to an individual can always be measured by a dollar equivalent. This presumption has led to the error of assuming that the utility value of life of an individual is ordinarily infinite. In this paper, we offer both logical proof and practical demonstration that the utility value of life of an individual cannot be infinite. At th...

T he article by Hopley and associates in this issue of the BJO (p 982) is a well performed study that utilises a form of healthcare economic analysis that is increasing in popularity throughout the healthcare literature. This instrument, cost utility analysis, has also been referred to by some as cost effectiveness analysis. A review of the healthcare literature using the key words ‘‘cost utili...

In this article we consider an optimal consumption/optimal portfolio problem in which an agent with constant relative risk aversion seeks to maximize expected discounted utility of consumption over the infinite horizon, in a model comprising a risk-free asset and a risky asset in which the risky asset can only be sold and not bought. The problem is an extension of the Merton problem and a speci...

Utility based models are common in both the risky and intertemporal choice literatures. Recently there have been efforts to formulate models of choices which involve both risks and time delays. An important question then is whether the concept of utility is the same for risky and inter-temporal choices. We address this question by fitting versions of two popular utility based models, Cumulative...
