We derive a general equilibrium linear relationship between the market prices of risks and market risk aversion under a continuous time stochastic volatility model completed by liquidly traded options. The relation is robust as it is valid for both endowment and production economies, and for...

The Cumulative Prospect Theory (CPT) is one of the most popular theories for evaluating the behavior of decision makers in the context of risk and uncertainty. This theory emerged as a generalization of the Expected Utility Theory (EUT) and being a relatively recent theory, its application has...

We propose a dynamic graph-theoretic model for ecosystem management as a control over networked system composed of target nodes and unmarked nodes. The network is represented by a complete graph, in which all vertices are connected by a unique edge. Target nodes are attracted by the objective...

Valuation of used machinery and equipment items and optimization of the overhaul policy are considered as interrelated problems. Non-traditional version of the discounted cash flow method is applied to their decision. The model uses available market and technical information and takes into...

This study develops a simple forecasting model using Japanese prefectural data. The Markov chain, known as a stochastic model, corresponds to a first-order vector auto-regressive (VAR) model. If the transition probability matrix can be appropriately estimated, a forecasting model using the...

Cost or revenue efficiency measurement based on the approach initiated by Farrell has received great attention from academics and practitioners since the fifties. Farrell’s approach decomposes cost efficiency into two different sources, viz. technical efficiency and allocative efficiency....
