What Drives Marginal Abatement Costs of Greenhouse Gases on Dairy Farms? A Meta‐modelling Approach

This paper examines the relationships between the marginal abatement costs (MAC) of greenhouse gas (GHG) emissions on dairy farms and factors such as herd size, milk yield and available farm labour, on the one hand, and prices, GHG indicators and GHG reduction levels, on the other. A two‐stage Heckman procedure is used to estimate these relationships from a systematically designed set of simulations with a highly detailed mixed integer bio‐economic farm‐level model. The resulting meta‐models are then used to analyse how MAC vary across farm‐level conditions and GHG measures. We find that simpler GHG indicators lead to significantly higher MAC, and that MAC strongly increase beyond a 1–5% emission reduction, depending on farm attributes and the chosen indicator. MAC decrease rapidly with increasing farm size, but the effect levels off beyond a herd size of 40 cows. As expected, the main factors driving gross margins per dairy cow also significantly influence mitigation costs. Our results indicate high variability of MAC on real life farms. In contrast to time consuming simulations with the complex mixed integer bio‐economic programming model, the meta‐models allow the distribution of MAC in a farm population to be efficiently derived and thus could be used to upscale to regional or sector level.     

Embodied Product Perception: Effects of Verticality Cues in Advertising and Packaging Design on Consumer Impressions and Price Expectations

As consumers increasingly turn to luxury brands and associated benefits, brand managers face the question how to convey luxury perceptions via marketing communications such as packaging and advertising design. Inspired by theories addressing embodied cognition and symbolic meaning portrayal, this paper argues that visual cues inspiring verticality perceptions (i.e., camera angle and advertising background orientation) affect luxury perceptions and, consequently, consumer evaluations and price expectations. Across three experiments, verticality cues fostered perceptions of product luxury but differentially affected price expectations and purchase considerations depending on product type. Moreover, findings show that effects of vertical orientation are more pronounced for participants high on sociable dominance. Implications of these findings for visual brand management are discussed.     

Cervical injuries in Sweden,a national survey of patient data from 1987 to 1999

Neck injuries are one of the most important injuries as they have the potential to influence the spinal cord. Data from most parts of the world are not sufficient to define a comprehensive view of mortality, morbidity, disability and handicap due to neck injuries. In Sweden, there are no data on the incidence of neck injuries. The aim of this study is to define the national incidence and causes of neck injuries in Sweden. An incidence study was undertaken with data from the injury surveillance program at the Swedish National Board of Health and Welfare. The investigation includes cervical vertebral fractures reported between 1987 and 1999, and cervical soft tissue injuries over a period of three years, from 1997 to 1999. Data between 1987 and 1996 were reported in ICD 9, while data from 1997 to 1999 were reported in ICD 10. During the study period, 14,310 non-fatal and 782 fatal cervical injuries occurred. A decreasing incidence for cervical fractures can be seen for the Swedish population, except for the elderly that have a slight increase in incidence. The incidence for cervical soft tissue injuries is almost constant. Cervical fractures demand longer periods of hospitalization than the soft tissue injuries. Transportation-related cervical fractures have dropped since 1991, while soft tissue injuries increased slowly between 1997 and 1999. Fall accidents are now the largest external cause of cervical fractures, and the population above 65 years accounts for almost 50% of the fall accidents. The male population has a higher incidence of cervical fractures, disregarding age. It is concluded that safety programs for transportation-related injuries in Sweden have been successful, while fall accidents are still substantial. Much more can be done to prevent neck injuries; especially to reduce the number of transportation-related cervical soft tissue injuries and fall injuries in the elderly population.     

What is Service Quality When ‘Service’ Equals Regulation?

A econometric model was developed to study Japanese tourist arrivals in British Columbia. Based on quarterly tourist arrival statistics, this study also examined the stability of the parameters of the model over nine holding periods. It was found that the income and habit variables were significant in all the nine holding periods while the exchange rate variable only contributed to the explanation of the dependent variable in two particular periods. The study also found that the number of Japanese tourists has reached full capacity in the summer season, but there is still potential for growth in the winter season. Implications of the findings to the development of the Japanese tourists market in British Columbia were discussed.     

TO OWN OR TO FRANCHISE?: THE INTERNATIONAL CONTROL DECISION FOR SERVICE COMPANIES

Franchising, which accounts for a significant share of the U.S. domestic service industry, has also become a major strategic alternative in the international expansion of U.S. service firms. This article attempts to explain the international franchising and control decision by U.S.-based service firms in terms of a theoretical framework that borrows from agency theory and transaction-cost analysis. Specifically, it attempts to answer the following question: Why would a well-established service firm choose to operate in certain countries through a franchising agreement whereas in others it would set up a wholly-owned subsidiary? In their empirical test of a sample of over 10,000 international service units that were either owned or franchised by 12 U.S. multinational service companies, the authors find that the most important determinants of the decision to franchise rather than own are the following four: (1) geographical distance from headquarters; (2) extent of cultural differences; (3) years of international experience; and (4) degree of concern about reputation or brand name. Greater geographic and cultural distance make service companies more likely to franchise, as do greater experience and familiarity with international business settings. Greater concern about brand name, by contrast, makes companies more likely to own than franchise. Measures of political and exchange risk have no detectable effect.     

The impacts of tourism investment on rural communities: Three case studies in South Africa

Significant research, both locally and internationally, has been undertaken on tourism development and its impacts on the empowerment of rural communities. This article analyses the extent to which three tourism projects in South Africa, namely the Makuleke tourism initiative, Umngazi River Bungalows and the commercialisation of Manyeleti Game Reserve, have improved the livelihoods of rural communities and contributed to rural economic development. The projects are analysed in terms of both their economic and non-economic benefits, as well as their contribution towards the attainment of certain key policy objectives of the South African government.     

Effects of machinery‐sharing arrangements on farm efficiency: evidence from Sweden

The effects of partnerships, in the form of machinery‐sharing arrangements, on farm efficiency are analyzed using data for Swedish crop and livestock farms. Efficiency scores are obtained using Data Envelopment Analysis and the findings suggest that efficiency is, on average, higher among partnership farms compared to nonpartnership farms. Moreover, partnership farms that are characterized by the most extensive form of collaboration, that is, that share all machinery with one or several other farms, display the highest average efficiency. In a two‐stage procedure in which efficiency determinants are analyzed in the second stage, the bootstrap procedures suggested by Simar and Wilson (2007) are applied in addition to the conventionally used Tobit regression. Participation in partnership arrangements is found to have a positive and statistically significant impact on farm efficiency.
