| Abstract: | The Atlantic bonito rush experienced in Turkey in the Fall of 2005 coincides with the avian influenza food scare that happened exactly at the same time-period in the country. In this research using time-series techniques, we investigate how the food scare and the excess fish caught jointly influence the demand for meat products in Turkey. |

| Abstract: | In Canada, where public ownership of forestland is prevalent, a central decision facing policy makers is how to allocate timber resources to private forest companies. Debates tend to focus around what proportion of the annual harvest should be devoted to markets opposed to long-term contracts. To give a guide to policy makers, we surveyed forest firms from New Zealand and Sweden where this decision is based purely on a commercial basis. On average, mills source fifty percent of their fibre from the market. However, using a fractional logit model, we test whether theories from transaction cost economics influence this decision. Results are consistent with transaction cost economics; firms decrease the proportion of fibre sourced from a market with increasing fibre specificity, capital intensity, and uncertainty. |

| Abstract: | This paper explores the contingent valuation method for environmental valuation. Issues are raised over the validity of the approach as a method of assessing the underlying preferences of individuals. An alternative interpretation is given to the method as a means of exploring underlying motivation in a rich vein of social psychological research. |

| Abstract: | Ecosystems are being characterised as goods and services to allow their valuation in monetary terms. This follows an orthodox economic approach to environmental values, but is also being undertaken by ecologists and conservation biologist. There appears a lack of clarity and debate as to the model of human behaviour, specific values and decision process being adopted. Arguments for ecosystems service valuation are critically appraised and the case for a model leading to value pluralism is presented. The outcome is to identify the need for value articulating processes which involve open deliberative judgment. In discussion of human motivations and judgement I make specific appeal to the works of philosopher Alan Holland. |

| Abstract: | This paper is an up-to-date survey of the state-of-the art in consumer demand modelling. We review and evaluate advances in a number of related areas, including different approaches to empirical demand analysis, such as the differential approach, the locally flexible functional forms approach, the semi-nonparametric approach, and a nonparametric approach. We also address estimation issues, including sampling theoretic and Bayesian estimation methods, and discuss the limitations of the currently common approaches. We also highlight the challenge inherent in achieving economic regularity, for consistency with the assumptions of the underlying neoclassical economic theory, as well as econometric regularity, when variables are nonstationary. |
