Despite the prominence of the risk-incentives trade-off in the agency theory, empirical evidence provides at best a mixed result. In this paper, we argue that these mixed results may be attributed to the heterogeneity of risk aversion magnitude among the agents and the outside options available on the market. We show that when an increase of the uncertainty amplifies the riskiness of principal’...

This paper presents a multi-objective resource-constrained project scheduling problem with positive and negative cash flows. The net present value (NPV) maximization and making span minimization are this study objectives. And since this problem is considered as complex optimization in NP-Hard context, we present a mathematical model for the given problem and solve three evolutionary algorithms;...

The purpose of this problem is to choose a set of project activities for crashing, in a way that the expected project time, cost and risk are minimized and the expected quality is maximized. In this problem, each project activity can be performed with a specific executive mode. Each executive mode is characterized with four measures, namely the expected time, cost, quality and risk. In this pap...

The model shows how a regulated monopolist’s price should change as random cost and demand parameters are revealed. The regulator has a Ramsey-type problem. With a linear tariff a trade-off between allocative efficiency and risk sharing typically exists. The attitudes of the consumer and the firm to both income and price risk determine how the price should move. Sufficient conditions are found ...

It is generally accepted that the three major dimensions of project success are time, budget, and quality. Most of the research in project planning is focused on the time-cost trade-off, and only a few papers have considered the three dimensions together. This paper describes the evolution of formulations for optimising project time-cost and quality, and continues by developing a new, non-linea...

In this paper we propose a methodology to generate trajectories for a mobile robot which uses an uncertain geometric map to estimate its position and orientation during its displacement. This methodology is based on the definition of particular paths and on defining a cost function to weigh the trade-off between expected localization gain and the risk due to the map uncertainty.

Increases in relative encephalization (RE), brain size after controlling for body size, comes at a great metabolic cost and is correlated with a host of cognitive traits, from the ability to count objects to higher rates of innovation. Despite many studies examining the implications and trade-offs accompanying increased RE, the relationship between mammalian extinction risk and RE is unknown. I...
