title: The marginal willingness-to-pay for attributes of a hypothetical HIV vaccine

authors: Cameron, Michael Patrick

subjects: HIV vaccine

abstract: This paper estimates the marginal willingness-to-pay for attributes of a hypothetical HIV vaccine using discrete choice modeling. We use primary data from 326 respondents from Bangkok and Chiang Mai, Thailand, in 2008-2009, selected using purposive, venue-based sampling across two strata. Participants completed a structured questionnaire and full rank discrete choice modelling task administered using computer-assisted personal interviewing. The choice experiment was used to rank eight hypothetical HIV vaccine scenarios, with each scenario comprising seven attributes (including cost) each of which had two levels. The data were analyzed in two alternative specifications: (1) best-worst; and (2) full-rank, using logit likelihood functions estimated with custom routines in Gauss matrix programming language. Knowledge of the relative importance of determinants of HIV vaccine acceptability is important to ensure the success of future vaccination programs. Future acceptability studies of hypothetical HIV vaccines should use more finely-grained biomedical attributes, and could also improve the external validity of results by including more levels of the cost attribute.

title: The Impact of Foreign Direct Investment on the Local Chilean Industry

authors: Salcedo-Claramunt, Carolina

subjects: Foreign Direct Investment

abstract: For a relatively small country located far from most major markets, Chile has been remarkably successful at attracting inward Foreign Direct Investment (FDI). However, the nature and extent of the contribution of inward FDI to Chile is not well understood. Most research has focused on the direct effects of FDI on the economy or the foreign affiliate. That is, there is a lack of research that considers the impact of FDI on the development of local industry. Therefore, this thesis main research issue is: “How does inward FDI impact on local industry in Chile?” It focuses on the impact of FDI at the firm level by assessing the indirect and direct linkages that foreign affiliates form with local firms, through which they may influence the upgrading of local industry, as well as identifying factors that may influence linkage formation. This thesis uses Scott-Kennel’s model of local industry upgrading as a guideline to address the main research issue. This model provides a micro-level explanation of the Investment Development Path (IDP), in turn, making it feasible to examine how the impact of FDI on local industry upgrading may occur. The model proposes a process of local asset augmentation (upgrading) that operationalizes the IDP by illustrating the mechanisms by which local firms may upgrade their resources and capabilities via linkages with foreign affiliates. However, Scott-Kennel’s model is based on the New Zealand context, which presents differences from the Chilean context. Hence, this thesis assesses the suitability of Scott-Kennel’s model in the context of a developing economy, Chile. From a methodological perspective the value of this thesis originates from the various challenges encountered during data collection by using quantitative methods that triggered the reconsideration of the research context and research questions that ultimately led to adopt a qualitative methodology using multiple case studies. Case firms included in the study are significantly foreign-owned affiliates operating within the service sector in Chile. This thesis provides evidence that FDI has a significant impact on the upgrading of local industry in the context of Chile, through direct effects over the affiliate, competitive effects, local sourcing, assistance linkages, corporate social responsibility linkages and collaborative agreements. The results also support Scott-Kennel’s findings that not all FDI is the same. Distinct groups of affiliates are distinguished according to their extent and quality of linkage formation. In so doing, it provides a starting point for identifying those affiliates that are more likely to be engaged in a variety of local linkages and those that are less likely to be so well integrated with the local industry. A key contribution of this thesis relates to the role of government policy in the process of local industry upgrading via FDI in the context of developing countries. The evidence suggests that while FDI policy may be neutral government policy plays a major role through directive industry policy and the provision of an investment environment which is stable politically and economically. Overall, the findings in this thesis relating to foreign affiliates and their activities in Chile will provide policy makers with a better understanding of the nature and outcomes of interaction between foreign and local firms.

title: Ngā Pakanga mō Wāhi Tapu: Battles over sacred places

authors: Joseph, Robert

abstract: Wāhi tapu are the sacred places of Māori in Aotearoa New Zealand. All cultures have sacred sites such as cemeteries, significant battlefields, and places of spiritual significance. Standout examples internationally include the ‘Weeping Wall’ in the Holy Land, Stonehenge in Britain, Maraeātea in the Pacific, and Intihuatana at Macchu Picchu in Peru. But unlike these sites, wāhi tapu are rarely a visible structure but rather a site or area within the landscape with values so significant that restrictions are warranted. In law, wāhi tapu are defined as a ‘place of special significance according to tikanga Māori’
 and ‘a place sacred to Māori in the traditional, spiritual, religious, ritual, or mythological sense’.
As the aphorism above emphasises, Māori historically were willing to die for land (and for women of course!), and wāhi tapu are the most sacred of places. Many battles have been fought over actual or proposed transgressions of their sacredness. In earlier years, blood was shed and men did die; today battles tend to occur in the Environment Court, but are just as passionate. Recent decades have seen conflicts where wāhi tapu were threatened by new highways, railroads, airports, prisons, residential and commercial developments, wind farms, power stations and waste dumps.
In this chapter, I discuss a number of the battles that have been fought over the development or preservation of wāhi tapu from first European contact up until the present time. I highlight the growing legal recognition of tikanga Māori in relation to these sacred landscapes, and conclude with a proposed pragmatic solution for all New Zealanders when negotiating developments over wāhi tapu. Having a
background in law and tribal affiliations, I discuss these tensions from both legal and kaupapa Māori perspectives.
