Fixed-path methods (FPMs) were introduced to manage situations where several individuals jointly operate a single technology (see [4]). In the production context, they consist in allocating marginal increments of output according to a proportions vector which changes along an arbitrary path. While very appealing from an incentives viewpoint under diminishing marginal returns, the asymmetry of t...

This study argues that diminishing marginal impatience (DMI ) as an intuitively plausible behavioural assumption of endogenous time preference has the potential for resolving important issues like the equity premium puzzle. It shows that, while applied to a model in the traditional overlapping generations (OG) framework, DMI is capable of generating assets prices with magnitude and volatility h...

Innovative clinical and translational research is often delayed or prevented by reviewers' expectations that any study performed in humans must be shown in advance to have high statistical power. This supposed requirement is not justifiable and is contradicted by the reality that increasing sample size produces diminishing marginal returns. Studies of new ideas often must start small (sometimes...

This article develops a general framework to guide the use of subgroup cost-effectiveness analysis for decision making in a collectively funded health system. In doing so, it addresses 2 key policy questions, namely, the identification and selection of subgroups, while distinguishing 2 sources of potential value associated with heterogeneity. These are 1) the value of revealing the factors asso...

In this paper, we investigate the total variation diminishing property for a class of 2-stage explicit Rung-Kutta methods of order two (RK2) when applied to the numerical solution of special nonlinear initial value problems (IVPs) for (ODEs). Schemes preserving the essential physical property of diminishing total variation are of great importance in practice. Such schemes are free of spurious o...

Top executives incentives and risk management are important contents of corporate governance research. However, few empirical data studies of risk management take top level manager incentives economic benefit into account, and the executive incentives effectiveness is unclear in most studies, the paper collected empirical data of listed companies in financial industry in 2008-2013, and we found...

Marginal utility theory prescribes the relationship between the objective property of the magnitude of rewards and their subjective value. Despite its pervasive influence, however, there is remarkably little direct empirical evidence for such a theory of value, let alone of its neurobiological basis. We show that human preferences in an intertemporal choice task are best described by a model th...
