| The sources of preference uncertainty in contingent valuation (CV) studies have rarely been investigated from a theoretical standpoint. This paper proposes a holistic theoretical framework of preference uncertainty that combines microeconomic theory with the theories of cognitive psychology. Empirical testing of the proposed theoretical model was carried out in Australia in the context of a national ‘Carbon Pollution Reduction Scheme (CPRS)’ to be introduced in 2010. Two separate ordered probit models for a certainty score associated with CV ‘Yes’ and ‘No’ responses were estimated. The results of the estimated regression models provide evidence supporting the hypotheses drawn from the theoretical model. |

| Australian farmers operate in one of the most risky farming environments in the world. They have to cope with numerous sources of risk including weather uncertainty, variable market prices, and institutional changes in their business management. This paper reports results from two case studies undertaken to examine the issues of farming risks and risk management strategies in Australia. The first case study found that unpredictable weather, financial risk, marketing risk, and personal risk were regarded as the major sources of risk among farmers in the Upper Eyre Peninsula of South Australia. The main risk management strategies used by farmers in that region included diversifying crop varieties, adopting minimum tillage farming practices, minimising the... |

| ABSTRACT Xylographellini beetles occur mainly in lands of the Southern Hemisphere. However, the taxonomy of Australian and Oriental species is incipient. The tribe comprises four genera, of which Scolytocis Blair, 1928 and Xylographella Miyatake, 1985 were recently redescribed and reported from Australia but without descriptions of new species. Here, three new species of Xylographellini are described: Scolytocis australimontensis sp. n. from Australia, with smooth interspaces of pronotal punctures; Scolytocis insularis sp. n. from the Pohnpei Island (Caroline Islands, Micronesia), with microstriated interspaces of pronotal punctures; and Xylographella frithae sp. n. from Australia, with six raised keels in elytral declivity. Scolytocis samoensis Blair,... |
