This discussion paper will briefly examine the concepts of risk and uncertainty, and the relevance of risk to decision making about animal health programs. Various techniques for dealing with uncertain cash flows will then be discussed, with particular emphasis on three extensions to the...

‘Risk’ has become a central theme in 21st-century policy thinking. The fact that individuals and families are vulnerable to a wide range of social, economic and other risks, and that collective action is needed to help reduce and manage these risks, has long been important in social...

Questions relating to the allocation and management of risk have played a central role in the development of the National Water Initiative, particularly as it has applied to the Murray-Darling Basin. The central issues of efficiency and equity in allocations are best understood by considering...

Dual approaches have proved their value in many areas of economic analysis. Until recently, however, they have been virtually ignored in the analysis of choice under uncertainty.In this paper, we present a dual formulation of choice under uncertainty based on a few simple assumptions about...

This paper develops a method for estimating the value of additional information to the individual livestock producer. In doing so it considers as part of the decision made by the farmer to vaccinate animals against B. bovis the decision to collect information on the health status of his herd...

This paper has two goals. First, we demonstrate that standard arguments and methods from production and duality analysis can be used to provide a comprehensive and general treatment of the value of information for a risk-averse firm with expected-utility (linear-in-probabilities) preferences and...

In the past year, climate change has moved from political controversy to political consensus; at least, in relation for price-based policies the need to limit emissions. Uncertainties remain but with both major parties proposing to develop an emissions trading regime, it is timely to highlight...

We consider an asset market traded three types of assets: the risk–free asset, the market portfolio and derivatives written on the market portfolio return. We determine a sufficient condition to guarantee that noise risk monotonically changes their derivatives. The condition is that...

We present a definition of increasing uncertainty, in which an elementary increase in the uncertainty of any act corresponds to the addition of an `elementary bet' that increases consumption by a fixed amount in (relatively) `good' states and decreases consumption by a fixed (and possibly...

Abstract. We define and discuss Savage games, which are ordinal games that are set in L. J. Savage’s framework of purely subjective uncertainty. Every Bayesian game is ordinally equivalent to a Savage game. However, Savage games are free of priors, prob- abilities and payoffs. Players’...
