Racing in two dimensions

In this paper we study an industry in which there is an ongoing sequence of R&D races between two firms. Firms are engaged in product innovation. Products are horizontally and vertically differentiated. There are two key characteristics/dimensions to products, and the level at which these are embodied in products can be increased by R&D. At each time firms can spend R&D on improving their product in one or both dimensions. We allow the possibility of economies scope — so R&D undertaken in one dimension can spillover to the other. The question we are interested in is whether a firm that is ahead in a single dimension but behind in another will focus all its R&D effort in the area in which it is ahead (product specialisation), or whether it will try to do R&D in both dimensions in the hope that it might get ahead in both and end up with a superproduct that dominates in both characteristics. The outcome of this R&D competition determines a Markov transition probability matrix determining the evolution of the industry. We show that when the R&D technology is characterized by constant returns then the only steady-state outcome is one in which the economy stays forever in a position in which one firm produces a super-product and the other gives up doing R&D altogether. This outcome is unaffected by the degree of economies of scope. When the R&D technology is characterised by decreasing returns, then the industry will visit all states and so will exhibit both product specialisation and superproduct dominance at various times. Now the extent of economies of scope matters and we show that the greater the extent of economies of scope, the less likely is the industry to exhibit product dominance, and the more likely it is to exhibit product specialisation.     

When Hosts Become Guests: Return Visits and Diasporic Identities in a Commonwealth Eastern Caribbean Community

The broad intent of this paper is to further contribute to the existing literature that addresses VFR tourism. It suggests that the return visit may ultimately be positioned as a form or type of travel within the larger category of VFR tourism, but a form or type that has built within it a more clear understanding of historic and social contexts and processes. The other broad intent of the paper is to highlight the importance of the relationship between the returning visitor, originating from diasporic communities abroad, and the host community as a stage for the negotiation of identities. The return visit is shown to reflect such underlying processes yet continue to incorporate aspects of individual motivation, which when taken together demonstrate the fluidity of diasporic spaces and transnational identity structures. Using data obtained from ethnographic fieldwork among social networks within the Commonwealth Eastern Caribbean community in Toronto, Canada, it is suggested that return visits are used to retain social histories and contextualise social and cultural backgrounds after migration. The implications for VFR tourism and the relationship between diasporas, transnationalism and tourism are discussed, as is a conceptual model of the return visit.     

Unethical use of wildlife in tourism: what's the problem,who is responsible,and what can be done?

Wildlife tourism is a huge global market, the revenue from which can promote local livelihoods and tourist education, enact conservation, and improve animal welfare. Such benefits arise if wildlife tourist attractions (WTAs) prioritise ethical deliverables above financial profit, but recent work has shown that the majority of WTAs have substantial negative animal welfare and conservation impacts. In the absence of global regulatory authorities, tourist revenue has become the ultimate arbiter of what constitutes acceptable use of animals in WTAs. Tourists, however, are not adequate assessors of WTAs’ animal welfare and conservation impacts: they lack the specialist knowledge required and are subject to a number of psychological biases that obscure the ethical dimensions of decisions to attend particular WTAs. This inadequacy is evidenced, and compounded, by overwhelmingly positive reviews on TripAdvisor (the industry-leading review site), even for WTAs with objectively poor ethical standards. Our suggested solution is to empower tourists by presenting unequivocal assessments of WTAs' animal welfare and conservation impacts, hosted in the fora that tourists already use to make their travel decisions. We would thereby promote a subjective norm that tourists should consider and limit their individual negative impacts when choosing which WTAs to visit.     

Healthcare Utilization and Healthy Lifestyles among Elderly People Living in Southern Europe: Recent Evidence from the SHARE

Recent demographic and economic research has analyzed the expected increase in the proportion of the population who are elderly. One consequence of an increasing elderly population is expansion in health care utilization, hence funding problems may arise.. European institutions encourage member states to promote good health among their citizens to mitigate the ageing effects on the health care system. Our objective was to examine the effect of healthy lifestyles among Southern European older adults on health care utilization by focusing on the number of outpatient doctor visits (ODV) and nights hospitalized (NH). Negative binominal regressions were conducted using a panel data set consisting of five waves (2004–2015) of the Survey of Health, Ageing and Retirement in Europe (SHARE). Our results add new empirical evidence on the effect of Southern European older adults’ lifestyles on their health care utilization. Engaging in vigorous physical activities reduces the number of ODV visits and NH by 7.8% and 28.25%, respectively. Moreover, smoking increases NH by 14.22%. Member states should establish policies to promote healthy lifestyles, with vigorous physical activities playing a key role, to reduce health services utilization.
