We formulate a dynamic framework for an individual decision-maker within which discovery of previously unconsidered propositions is possible. Using a standard game-theoretic representation of the state space as a tree structure generated by the actions of agents (including acts of nature), we...

Traditional regulation in the food safety domain has been in the form of mandatory, inflexible food safety controls that are applied to firms. There has been a trend away from this regulatory paradigm towards more co-regulation and self-regulation by industry. This paper investigates the...

Like the human immune system, a biosecurity system is a constellation of responses to external attacks comprising of many facets, a number of which can change to optimize the response to these unwanted intrusions. When either system hits the wrong target, or is inhibited or crippled somehow, the...

We give a formal treatment of optimal risk sharing contracts in the face of ambiguity. The central idea is that boundedly rational individuals do not have access to a language sufficiently rich to describe all possible states of nature. The ambiguity in a contract arises from contractual clauses...

We present a computational model of fishing fleet dynamics for the Queensland coral reef line fishery. The model runs in a two dimensional space with agents moving between port and the collection of available reefs. The model of rationality is based on the haystack models of game theory, such...

In this paper, estimates of value for recreational fishing are reported for three major freshwater impoundments in Queensland, Australia, using both travel cost and contingent valuation methods. The research results that are reported have two key methodological distinctions from previous studies...

Water resource management is a complex process, which requires suitable policy tools that are able to meet objectives of economic efficiency, social equity and environmental sustainability. Meanwhile, irrigation industry has to change its habitual behaviour in managing water when faced with...

Com o objetivo de solucionar os problemas enfrentados pelos cafeicultores brasileiros em diversas regiões cafeeiras, foi implantado o Consórcio Brasileiro de Pesquisa e Desenvolvimento do Café (CBP&D-Café), que tem como finalidade o desenvolvimento dos trabalhos de pesquisa agropecuária, em...
