- Item2050 Scenarios for long-haul tourism in the evolving global climate change regime(Multidisciplinary Digital Publishing Institute (MDPI), 2012-12) Vorster, Shaun; Ungerer, Marius; Volschenk, JakoTourism and its “midwife”, aviation, are transnational sectors exposed to global uncertainties. This scenario-building exercise considers a specific subset of these uncertainties, namely the impact of the evolving global climate change regime on long-haul tourism (LHT), with a 2050 horizon. The basic problematique is that unconstrained growth in aviation emissions will not be compatible with 2050 climate stabilisation goals, and that the stringency and timing of public policy interventions could have far-reaching impacts—either on the market for future growth of LHT, or the natural ecosystem on which tourism depends. Following an intuitive-logic approach to scenario-building, three meta-level scenarios that can be regarded as “possible” futures for the evolution of LHT are described. Two of these, i.e., the “grim reaper” and the “fallen angel” scenarios, are undesirable. The “green lantern” scenario represents the desired future. Long-haul tourist destinations should heed the early warning signals identified in the scenario narratives, and contribute towards realising the desired future. They should further guard against being passive victims if the feared scenarios materialise, by adapting, repositioning early upon reading the signposts, hedging against risks, and seizing new opportunities.
- ItemCan sugar provide a spark? : wanted! greener energy : is South Africa doing everything in its power to come clean?(Stellenbosch : University of Stellenbosch Business School, 2007-08) Norris, Grant; Volschenk, JakoThe province of KwaZulu-Natal in South Africa has two strong bioindustries, namely sugar and forestry, which produce considerable volumes of residue. What is the potential of these two waste resources to deliver cost-effective, green electricity? This question led to research at the University of Stellenbosch Business School (USB) to determine to what extent these two resources can offer feasible and economically viable sources of electric energy.
- ItemCreation and appropriation of socio-environmental value in coopetition(Elsevier, 2016) Volschenk, Jako; Ungerer, Marius; Smit, E. van der M.ENGLISH SUMMARY : Although much has been written about value in coopetition initiatives, the dynamics of value creation and appropriation remain poorly articulated. This paper explores the types of value and the dynamics of value creation and appropriation when competitors cooperate. The research provides some suggestions towards semantic clarity and introduces new dimensions to the existing value creation and appropriation literature. We also present the Coopetition Value Matrix (CVM), an expanded typology that aids in the understanding of value dynamics in coopetition. Constructing the CVM required the incorporation of stakeholder theory and the concept of socio-environmental value, two aspects that are under-explored in coopetition research. We applied the CVM to a case of environmental coopetition in the South African wine industry, which provided us with empirical illustrations of the dynamic interaction of different types of value.

- ItemWillingness to pay for green electricity : a review of the contingent valuation literature and its sources of error(Elsevier, 2016) Oerlemans, Leon A. G.; Chan, Kai-Ying; Volschenk, JakoENGLISH SUMMARY : Contingent valuation is widely used due to its flexibility in valuing a wide variety of nonmarket goods. Although this method has important benefits, its validity and reliability are often criticised. This paper reviews the literature on the use of contingent valuation for measuring willingness to pay (WTP) for electricity generated from renewable energy sources (green electricity). A literature review, conducted on a sample of 51 peer-reviewed studies, shows that the vast majority of contingent evaluation studies stems from developed economies. Furthermore, most frequently used WTP elicitation techniques are open-ended and dichotomous choice approaches, which tend to produce varying levels of WTP. Studies dealing with the antecedents of WTP are predominantly inspired by the theory of reasoned action or by its extension, the theory of planned behaviour. This paper identifies five common errors in contingent valuation methods and discusses a number of remedies to deal with these errors in WTP research.
