Evolution of the Amazonian frontier: Land values in Rondônia, Brazil

Patterns in property values provide strong signals about the future and sustainability of land use. This paper analyzes the determinants of land value in an Amazonian frontier settlement. We estimate hedonic price functions to identify factors that affect the value of farm properties in the western Brazilian Amazon. Distance to market explains nearly one-third of the variation in farm value, as predicted by the von Thünen model. After controlling for location relative to the central market and for municipality, we find that investment in the farms (as reflected in the stocking rate of pastures and the establishment of home gardens) has the next largest impact on land value. The value per hectare of land is negatively related to total lot size, suggesting that any economies of scale are outweighed by the cost of accessing remote corners of large properties. We do not find that land values are related to available measures of biophysical factors or to historic or current land use. Our results do not identify any premium for forest cover or for land uses considered to be more sustainable than pasture on the property itself. However, farm values are affected by neighboring land cover, specifically, the extent of barren land. Thus, local knowledge of factors contributing to future productivity, as summarized in land values, confirms that soil exhaustion can lead to a general decline in property values, while investments in a property both as a homestead and as a farm can help sustain frontier settlements.     

Consumer Attitudes to Genetically Modified Food in Norway

There is a lack of public acceptance of genetically modified (GM) food products in Europe. Using a dichotomous choice contingent valuation methodology, we find that, on average, survey respondents with a positive attitude toward the use of biotechnology in food production, higher educated, younger, and male need less of a discount to choose to purchase bread made with GM wheat. Further, we estimate confidence intervals for the mean discount required for consumers to choose GM bread. The 95% confidence interval for the mean discount required for the respondents to choose the GM bread is a 37% to 63% discount relative to conventional bread.     

Assessing cost‐effectiveness when environmental benefits are bundled: agricultural water management in Great Barrier Reef catchments

Using economic analysis to prioritise improvements in environmental conditions is particularly difficult when multiple benefits are involved. This includes ‘bundling’ issues in agricultural pollution management, where a change in management action or farming systems generates multiple improvements, such as reductions in more than one pollutant. In this study, we conceptualise and compare two different approaches to analysing cost‐effectiveness when varying bundles of benefits are generated for a single project investment. Each approach requires data to be transformed in some way to allow the analysis to proceed. The index approach requires the transformation on the benefits side so that the effects of multiple pollutant changes can be combined into a measure for each project which can then be compared to costs. By comparison, the disaggregation approach requires the transformation on the costs side where costs for each project have to be apportioned across the different pollutants involved. The paper provides novel insights with an application to agricultural water quality improvements into the Great Barrier Reef in Australia, demonstrating that while both approaches are effective in prioritising projects by cost‐effectiveness, the disaggregation approach provides more insightful results and values that may be relevant for use as upper value guidelines in future project selection.     

Choice Certainty and Consistency in Repeated Choice Experiments

The main objective of this study is to examine how repeated choice affects preference learning in stated preference experiments. We test different hypotheses related to preference learning by analyzing response patterns and asking respondents in a choice experiment to report their experienced certainty when going through the choice tasks. In a split-sample test, we show that follow-up choice certainty questions are procedural invariant. The self-reported certainty results indicate that learning occurs, but econometric testing procedures do not identify any significant impact of learning effects on parameter estimates or variance across choice tasks. Additional tests of choice consistency suggest that preferences in the choice experiment are stable and coherent.     

Anonymity in Computer-Mediated Communication: More Contrarian Ideas with Less Influence

Anonymity is thought to be an important means for ensuring a free exchange of ideas by encouraging the expression of minority viewpoints. However, we suggest that anonymity’s reduction in awareness of others potentially affects the expression and interpretation of comments that are made during a discussion. In particular, anonymity will increase the likelihood that comments will be made that are contrary to the majority opinion while at the same time decreasing the effect that those contrary arguments have on other group member’s opinions. This paper reports experimental results showing that anonymity led to more overall participation in discussions of ethical scenarios. However, equality of member participation did not differ between anonymous and member-identified groups, and anonymous groups had significantly higher awareness-related comments. This leads to the conclusion that additional participation in anonymous groups accommodates reduced awareness rather than reflecting the increased participation of normally reticent group members. In addition, anonymity led to more arguments in support of questionable behavior, suggesting that the freeing effects of anonymity apply to the social desirability of arguments. Finally, there was less change in opinion under conditions of anonymity than when comments were identified, suggesting that anonymous arguments have less influence on opinions than identified comments.     

Strategic responses to food safety legislation

This paper assesses the responses made by food companies to changes in food safety legislation. Such responses are assessed in three ways. Firstly, an assessment is made as to why strategic responses to such legislation might be different to general strategic behaviour. Secondly a conceptual framework is presented and an examination of supply chain organisational response is made. Finally, the paper addresses the question of external marketing responses to food safety legislation. The paper concludes that food safety legislation is different, and often requires very swift strategic actions to be effective. Like other forms of legislation, however, food safety issues can also provide incentives and opportunities to well-managed and market-orientated firms.     

Innovation and Future Direction of Supply Chain Management in the Canadian Agri-food Industry

The supply chains for agri-food products in Canada are being shaped by a number of forces including the globalization of markets, technological change and the increased focus by consumers — both domestically and internationally — on issues such as food safety, quality assurance and environmental sensitivity. This paper explores these changes, offering an explanation of why they are occurring, discussing the driving forces for change and providing examples from alternative supply chain structures in the Canadian agri-food sector.     

Friend or Foe?— Farmer Perceptions of Biotechnologh1

This paper is the result of survey investigation the attitudes of Western Canadian farmers toward two biotechonological products, ENFIX-L and PB-50. Farmers were asked to rate both the importance and the performance of 21 attributes of the products. Soil depletion was found to be an important concern to many farmers. personal and environmental risks were less of a concern. Overall, it was found that the non-biotech-nological aspects of a product would prevail in purchasing decisions.     

Metamorphosis in hospitality: A tradition of sexual harassment

This study measures the incidence and tolerance of sexual harassment in hospitality in an effort to understand its causes. It examines the tradition of sexual behaviour in hospitality, exacerbated by hierarchical structures, the nature of hospitality work, the characteristics of typical front line workers, customers’ reduced sense of responsibility, and an emphasis on meeting customers’ needs. Customer contact is shown to be a key predictor of harassment, especially for young European women. The typical profiles of hospitality staff and the nature and traditions of the industry are considered important causes of harassment in hospitality.     

Minimum Wages and Collective Bargaining: What Types of Pay Bargaining Can Foster Positive Pay Equity Outcomes?

Using data from interviews and collective agreements in five European countries, this article analyses the relationship between collective bargaining and the minimum wage. In a context of changing minimum wage policy and competing government objectives, the findings illuminate how pay bargaining strategies of trade unions and employers shape the pay equity effects of minimum wage policy. Two general forms are identified: direct responses to a changing national minimum wage, and responses to the absence or weakness of a national minimum wage. The article explains how particular intersections of minimum wage policy and collective bargaining, together with country and sector contingencies, shape the form of pay bargaining and pay equity outcomes.
