Counting carbon: historic emissions from fossil fuels,long-run measures of sustainable development and carbon debt

This article examines how to account for the welfare effects of carbon dioxide emissions, using the historical experiences of Britain and the USA from the onset of the industrial revolution to the present. While a single country might isolate itself from the detrimental effects of global warming in the short run, in the long all countries are unable to free ride. Thus, we support the use of a single global price for carbon dioxide emissions. The calculated price should decrease as we move back in time to take into account that carbon dioxide is a stock pollutant, and that one unit added to the present large stock is likely to cause more damage than a unit emitted under the lower concentration levels in the past. We incorporate the annual costs of British and US carbon emissions into genuine savings, and calculate the accumulated costs of their carbon dioxide emissions. Enlarging the scope and calculating the cumulative cost of carbon dioxide from the four largest emitters gives new insights into the question of who is responsible for climate change.     

Managerial perceptions of service-infused IORs in China & India: A discursive view of value co-creation

This paper explores the managerial challenges facing firms seeking to build relationships with other network actors while doing business in foreign markets. By taking a critical perspective on an area of increasing importance in both manufacturing and service sectors, that of value co-creation, the paper explores how managers in different cultural contexts make sense of the notion of ‘value’ in inter-organizational B2B relationships between New Zealand service and service-infused supplier firms and buyers in China and India. From an analysis of the interview-based accounts on both sides of the buyer–seller dyad marked differences emerge regarding value-creation within managers' discourse around partnerships, collaboration and cooperation. Our findings suggest that the Indian manager's discursive use of ‘partnership’ draws on service-dominant logic in viewing this type of interaction as a means for co-creating value; they and their New Zealand suppliers are jointly involved in co-creating value within a service system, creating value-in-use. In contrast, the predominant perspective seen in the discourse of Chinese managers is the use of cooperation as a means of making transactions more cost-effective, or to fill gaps in their supply chains, resulting in the creation of transaction-based, co-production of value, which suggests a value-in-exchange orientation. In both cases, there is repeated reference to more peripheral actors whose efforts result in what we interpret as network value creation, based on their interactions with actors within the buyer–seller dyad.     

How sensitive are bargaining outcomes to changes in disagreement payoffs?

We use a human-subjects experiment to investigate how bargaining outcomes are affected by changes in bargainers’ disagreement payoffs. Subjects bargain against changing opponents, with randomly drawn asymmetric disagreement outcomes that vary over plays of the game, and with complete information about disagreement payoffs and the cake size. We find that subjects only respond about half as much as theoretically predicted to changes in their own disagreement payoff and to changes in their opponent’s disagreement payoff. This effect is observed in a standard Nash demand game and a related unstructured bargaining game, in both early and late rounds, and is robust to moderate changes in stake sizes. We show theoretically that standard models of expected utility maximisation are unable to account for this under-responsiveness, even when generalised to allow for risk aversion. We also show that quantal-response equilibrium has, at best, mixed success in characterising our results. However, a simple model of other-regarding preferences can explain our main results.     

Sustainable Tourism or Sustainable Development? Financial Crisis,Ecotourism, and the 'Amazing Thailand' Campaign

Although the issues of sustainable tourism and sustainable development are receiving increasing attention from tourists, government planners and scholars, few studies have examined their overlap, tensions and complex linkages in practice. In southern Thailand, the sustainability of tourism, defined as the ongoing growth and survival of the tourism industry, has compromised the ecological sustainability of key tourism destinations sites. The recent financial crisis has forced the Thai government to sacrifice long-term sustainability for the sake of quick, and desperately needed foreign exchange. The 'Amazing Thailand' promotional campaign, which aims to attract 17 million tourists over 1998 and 1999, promises to exacerbate further the environmental degradation of tourism destinations in southern Thailand by pushing for enhanced tourist numbers. Ironically, by changing the composition of tourist arrivals (and in particular, attracting more European and North American tourists) the currency devaluations associated with the Asian financial crisis may simultaneously boost demand for nature-based tourist activities in southern Thailand while also adding stress to ecologically deteriorating destinations.     

Forays into the backstage: volunteer tourism and the pursuit of object authenticity

Volunteer tourism is a form of travel that combines traditional leisure pursuits with opportunities to volunteer in an organized fashion. The popularity of volunteer tourism stems from many factors, but the one motivation that appears in virtually every study is a desire for object authenticity, defined as the authenticity of toured objects, people, and settings. The purpose of this paper is to explore the role played by object authenticity in the motivations and experiences of volunteer tourists in the province of Chiang Mai in northern Thailand. Based on interviews with 62 volunteers and 15 directors, managers, and staff members from volunteer tourism organizations based in Chiang Mai, this paper argues that volunteer tourists conceive of object authenticity both as a package of cultural stereotypes focused on authentic people, and as authentic backstage settings where ‘real’ Thai reside. Aside from demonstrating that the desire for object authenticity is the central motivation for international volunteers in northern Thailand, this study indicates that the pursuit of object authenticity is complicated by language barriers, the potential staging of authenticity on the part of locals, and the need to balance familiarity with alterity in the carefully selected ‘voluntourscapes’ in which volunteer tourism takes place.     

Skill transferability and the earnings of immigrants

Using data on immigrants from the Canadian Census, we compare immigrants who received a bachelor's degree from a Canadian university to immigrants who receive a bachelor's degree in their home country, in order to investigate the returns to skills acquired in Canada versus skills acquired abroad. Our measure of skill is based on postsecondary fields of study linked to the O*NET matrix of skills and competencies. We find that immigrants educated in Canada receive higher returns to their communication skills than those educated abroad. To a lesser degree, they also receive higher returns to their logical and technical skills. These gaps in skill returns explain the entirety of Canadian-educated immigrant's 10% earnings advantage. Our results are robust to controlling for the quality of universities in the immigrant's country of study and for occupation and industry choice. The gaps are stable across time and across quantiles of the immigrant earnings distribution.     

A Nonlinear Model of the Term Structure of Interest Rates

We present an economically motivated two–factor term structure model that generalizes existing stochastic mean term structure models. By allowing a certain parameter to acquire dynamical behavior we extend the two–factor model to obtain a nonlinear three–factor model that is shown, in a deterministic version, to be equivalent to the Lorenz system of differential equations. With reasonable parameter values the model exhibits chaotic behavior. It successfully emulates certain properties of interest rates including cyclical behavior on a business cycle time scale. Estimation and pricing issues are discussed. Standard PCA techniques used to estimate HJM type models are observed to be equivalent to dimensional estimates commonly applied to 'spatial data' in nonlinear systems analysis.
It is concluded that techniques commonly used in the analysis of nonlinear systems may be directly applicable to interest rate models, offering new insights in the development of these models. Tests of nonlinearity in interest rate behavior may need to focus on long cycle times.     

Mapping and analysing virtual outcrops

Laser scanning is a very efficient way to generate realistic, high-resolution digital models of 3-D geological outcrops. This paper discusses the methodologies involved in the creation and analysis of virtual outcrops, based on laser scanner data. The visualisation of the laser scanner data as a photorealistic 3-D object is described. Geological features picked out on the virtual outcrop (e.g. fractures, faults or bedding planes) can be extrapolated outward, into space, and inward, into the subsurface, using tension surfaces.
