Companies are increasingly choosing to procure their power from renewable energy sources, with their own set of potential challenges. In this paper we focus on contracts to procure electricity from renewable sources that are inherently unreliable (such as wind and solar). We determine the...

When risk averse forecasters are presented with risk neutral proper scoring rules, they report probabilities whose ratios are shaded towards 1. If elicited probabilities are used as inputs to decision-making, naive elicitors may violate first-order stochastic dominance.

The literature on proper scoring rules has mostly studied the case of risk neutral agents. We analytically investigate how risk averse, expected utility maximizing forecasters behave when presented with risk neutral proper scoring rules. If the state variable is binary, risk averse agents shade...

We show that Risk parity and risk-based models in general can be rationalized as an optimal decision under ambiguity. Risk-based framework represents an extension of Maximum diversification approach of Choueifaty and Coignard (2008) in the presence of ambiguity in risk-adjusted expected returns

We establish a class of fully nonlinear conditional expectations. Similarly to the usage of linear expectations when a probabilistic description of uncertainty is present, we observe analogue quantitative and qualitative properties. The type of nonlinearity captures the agents sentiments of...

We develop a nonparametric procedure, called the lattice method, for testing the consistency of contingent consumption data with a broad class of models of choice under risk and under uncertainty. Our method allows for risk loving and elation seeking behavior and can be used to calculate, via...

Among the most popular models for decision under risk and uncertainty are the rank-dependent models, introduced by Quiggin and Schmeidler. Central concepts in these models are rank-dependence and comonotonicity. It has been suggested in the literature that these concepts are technical tools that...

This paper proves that the (negative) certainty equivalent (CE) in reference-dependent decision theories (such as Prospect Theory) always satisfies the well-known axiomatic characterisation of a monetary risk measure, although in rational Expected Utility Theory this only holds in special cases....

This paper analyzes the problem faced by a risk-averse firm considering how much to invest in a risky project. The firm receives a signal about the value of the project. We derive necessary and sufficient conditions on the signal distribution such that (i) the agent's investment is nondecreasing...
