| We present a theoretical framework for understanding the relationship between anchoring bias, hypothetical bias, and cheap talk in constructed markets. In our theory, interviewers provide agents with signals such as cheap talk and bid values while eliciting the value for nonmarket goods. In response to these signals, agents revise their prior distributions over the value of the good. Previous empirical studies have failed to account for the interaction between cheap talk and anchoring during this updating process, leading researchers to incorrectly assess the effects of cheap talk in reducing hypothetical bias. In particular, we predict that cheap talk will appear to be more effective for relatively large bids. We test our theory in an experimental... |

| We develop a Bayesian implementation of the standard optimal hedging model to analyze the impact of hedgers' subjective views on their hedging behavior. The results show the subjective views have a substantial impact on hedgers' optimal positions, explaining the large cross-sectional and time series variation of hedging positions in practice. |

| The Queensland Fruit Fly (QFF) — Bactrocera tryoni — poses a significant threat to horticultural production in Victoria causing losses of fruit and jeopardising access to interstate and international markets. The Victorian Government implements and largely funds an area freedom program to manage QFF. Concern about the record number of outbreaks in 2007-08 and the escalating costs of maintaining the current management regime, led the Victorian Department of Primary Industries to review the program to identify improved strategies for managing QFF. As part of this work, a benefit cost analysis (BCA) of alternative strategies has been conducted. While the BCA method is well established, in general few studies are publicly available for area freedom programs.... |

| Because original high-quality non-market valuation studies can be expensive, perhaps prohibitively so, benefits transfer (BT) approaches are often used for valuing, e.g., the outputs of multifunctional agriculture. Here we focus on the use of BT functions, a preferred method, and address an under-appreciated problem – variable selection uncertainty – and demonstrate a conceptually superior method of resolving it. We show that the standard method of value-function BT, using the full estimated model, may generate BT values that are too sensitive to insignificant variables, whereas models reduced by backward elimination of insignificant variables pay no attention to insignificant variables that may in fact have some influence on values. Rather than searching... |

| One of the outcomes of the merger of the Farm Management Society of Central South Australia and AARES was a project to record the history of the Australian Farm Management Society. As part of this project it was decided to develop a bibliography of Australian Farm Management Research and Publication. It has been produced as a web site to facilitate further development. One of the problems is what to include or exclude from the bibliography. This hinges on one's definition of "Farm Management". The approach taken will be explored and progress to date reported. |

| This study analyzes the demand for cigarettes fitting observed zero outcomes with a trivariate model consisting of an equation for the starting smoking decision, an equation for the quitting decision, and an equation that models the level of cigarettes consumed. Five competing specifications are considered to explain level, with the ordered probit, which accommodates pile-ups of counts in the dependent variable, providing the best fit. Marginal effects of explanatory variables are calculated providing strong evidence of race and gender differences in consumption patterns. The estimated marginal effects are robust to alternative categorizations of the level of cigarettes. |

| NPV and LEV are established and common approaches to valuing single rotation and infinite rotation forests respectively, when the rotation age is fixed in advanced. More recently, Real Options approaches have been employed to value single and infinite rotation forests with a flexible harvest age. Under a stochastic timber price process, it has been shown that the valuation of a flexible rotation forest is equal or higher than that of a fixed rotation forest, because a flexible harvest regime delays the harvest if the timber price is not favourable, whereas a fixed harvest regime would proceed to harvest regardless of the price. Often, valuation of fixed and flexible rotation ages are compared using 2 different methods – NPV (or LEV) and Real Options. The... |

| The use of protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a two-species fishery will be used to test the performance of protected areas as a management tool in a fishery with heterogenous environments. Protected areas are analysed under density-dependent and sink-source dispersal relationships between environments within the fishery. Differing levels of management control over fishery resource extraction are analysed. The model is applied to Manning Bioregion in NSW. The focus of the study is placed on the biological and institutional characteristics that yield benefits to the fishery. |

| Conservation and restoration of native vegetation is often a gradual process which may require many years to transform an ecosystem from one vegetative state to a target ecosystem. This process is stochastic, with some changes potentially irreversible. In contrast, contracts with landholders to undertake conservation measures on their property are typically for less than ten years and often make no contingencies for re-contracting at the end of the contract period. The risk to land holders and conservation agencies of contracts not being renewed and the consequent potential loss of previous investment means including covenants in conservation contracts may be attractive to both parties. A model is developed to empirically examine the optimal dynamic... |

| American foulbrood (AFB) is considered the most significant brood disease of bees in Western Australia. The Department of Agriculture of Western Australia (DAWA) provides assistance to apiarists by way of quarantine and surveillance measures under the AFB control program. A bio-economic evaluation was considered necessary by the department for setting future policy direction. As a way forward, a number of risk analysis scenarios were simulated to estimate the future prevalence rate of AFB in the absence of the present program. This epidemiological investigation was complemented by an economic evaluation which identifies the extent of benefit that flows through to direct beneficiaries. The paper provides a comprehensive bio-economic analysis and suggests... |

| Since its first detection in the North Central region in July 2000, the soybean aphid (Aphis glycines Matsamura) has caused considerable loss in soybean (Glycine max L.) yield, bean quality, and producer income. Discovered first in Wisconsin and then in adjoining states, it is currently distributed in 21 US states and parts of Canada. In 2003, over 42 million acres of soybean in the North Central US were infested and over 7 million acres were treated with insecticides to control soybean aphid (Landis et al. 2003). Populations exceeding 24,000 aphids per plant and 40% losses in seed yield have been reported (DiFonzo & Hines 2002). Even prior to the outbreak of 2003, the Soybean Strategic Pest Management Plan identified soybean aphid as one of the key... |

| Wetland ecosystems on privately owned farms such as those on the Murrumbidgee River Floodplain in the state of New South Wales, Australia provide a mix of potentially valuable outputs to their owners and the wider community. The mix of values generated is dependent on the biophysical status of the wetlands, which in-turn, is dependent on the land management in and around these multiple-output ecosystems. Despite the range of private and public values generated, management decisions are based primarily on the private values that landowners receive. These private land management decisions also affect social values. Hence, there is potentially a demand for public policy to influence decisions based on the social values wetlands generate.
