Forecasting the Adoption of GM Oilseed Rape: Evidence from a Discrete Choice Experiment in Germany

This paper explores farmers’ willingness to adopt genetically modified (GM) oilseed rape prior to its commercial release and estimates the ‘demand’ for the new technology. The analysis is based upon choice experiments with 202 German arable farmers. A multinomial probit estimation reveals that GM attributes such as gross margin, expected liability from cross pollination, or flexibility in returning to conventional oilseed rape significantly affect the likelihood of adoption. Neighbouring farmers’ attitudes towards GM cropping and a number of farmer and farm characteristics were also found to be significant determinants of prospective adoption. Demand simulations suggest that adoption rates are very sensitive to the profit difference between GM and non‐GM rape varieties. A monopolistic seed price would substantially reduce demand for the new technology. A monopolistic seed supplier would reap between 45% and 80% of the GM rent, and the deadweight loss of the monopoly would range between 15% and 30% of that rent. The remaining rent for farmers may be too small to outweigh possible producer price discounts resulting from the costs of segregating GM and non‐GM oilseed rape along the supply chain.     

How well do conservation auctions perform in achieving landscape‐level outcomes? A comparison of auction formats and bid selection criteria

This paper studies the performance of auction design features regarding pricing mechanisms and bid selection criteria for securing wildlife zones across different holdings. We compare two pricing mechanisms: a discriminatory‐price auction and a uniform‐price ascending auction, and four bid selection criteria on the basis of: total bid, bid‐per‐value ratio, bid‐per‐area ratio and a mixed criterion where bids are formed on the basis of cost but they are selected based on the bid‐per‐value ratio. We develop a best‐response group‐bidding model for a discriminatory‐price auction where bidders form optimal group bids for individual wildlife zones. In the uniform‐price ascending auction, individual landholders respond to prices, which are successively raised by the auctioneer and whenever all the landholders from a single zone agree to participate (i.e. the first zone is formed), the auction stops. Based on numerical simulations using a bio‐economic model of malleefowl conservation, we observe that the discriminatory‐price auction is more cost‐effective than the uniform‐price ascending auction. However, the budgetary cost‐effectiveness of a discriminatory‐price auction is sensitive to bidder uncertainty about the number of competing bidder groups and the highest cost of establishing a wildlife zone among these groups. In terms of bid selection, the mixed bid selection criterion performs best. We discuss the policy implications of these findings.

Conceptualizing and operationalizing nodal tourism functions

This paper reviews conceptualizations of nodal functions and presents a methodology for identifying and measuring the tourism functions of specific places with reference to place competitiveness. The methodology, which combines measures of length of stay and purpose of visit, is illustrated by a survey-based comparative analysis of ferry passengers traveling between two tourist nodes in New Zealand: Wellington and Picton. The results show distinctive differences between the two places in terms of their multiple functions expressed as origins, gateways, stopovers and destinations. Opportunities for modifying functions appear to be greatest amongst international travelers.     

基于经济发展的资源型地区金融结构优化策略

资源的开发利用在现代工业化城市化进程中颇受重视,它不仅带动了资源型地区经济发展,也为经济繁荣做了贡献。资源型经济对矿产资源和能源消耗日益增加,资源过渡消耗与经济发展之间的矛盾越来越突出。要想解决这个矛盾,只有促进金融发展,既能使资金流向技术含量高的产业,又能为经济提供足够的发展资金。本文阐述了资源型地区如何有效利用资源及如何制定有效的金融结构策略才会使地区经济有效发展。
