Safety, in Numbers

We introduce a way to compare actions in decision problems. An action is safer than another if the set of beliefs at which the decision-maker prefers the safer action increases in size (in the set inclusion sense) as the decision-maker becomes more risk averse. We provide a full characterization of this relation and discuss applications to robust belief elicitation, contracting, Bayesian persuasion, game theory, and investment hedging

Optimal Information Design for Search Goods

We consider a monopoly pricing problem in which a consumer with an uncertain valuation of a search good receives a signal of value before deciding whether to visit the seller. She discovers her true value upon visiting and before purchase. We characterize the consumer-optimal and seller-worst signals in such an environment and deliver two main insights. First, both the consumer-optimal and seller-worst signals generate a unit-elastic demand. Second, the two signals coincide if and only if visitation costs are sufficiently small

Plant Virus and Virus-like Disease Threats to Australia’s North Targeted by the Northern Australia Quarantine Strategy

The Northern Australia Quarantine Strategy (NAQS) is a biosecurity initiative operated by the Australian federal government’s Department of Agriculture, Water and the Environment (DAWE). It is unique worldwide because it deals specifically with the potential arrival via unregulated pathways of exotic threats from overseas in a vast and sparsely populated region. It aims to protect the nation’s animal- and plant-based production industries, as well as the environment, from incursions of organisms from countries that lie immediately to the north. These are diseases, pests, and weeds present in these countries that are currently either absent from, or under active containment in, Australia and may arrive by natural or human-assisted means. This review article focuses on the plant viruses and virus-like diseases that are most highly targeted by the NAQS program. It presents eight pathogen species/group entries in the NAQS A list of target pathogens, providing an overview of the historical and current situation, and collates some new data obtained from surveillance activities conducted in northern Australia and collaborative work overseas
