This dissertation is concerned with enhancing the utility of social capital by developing and testing a comprehensive and measurable framework as a tool for researchers, policy-makers, and development theorists and practitioners. A framework was developed for measuring the degree to which different forms of social capital reside in a community and for distinguishing community-to community variations. The Framework was also designed to identify the accumulation of social capital in relation to structural characteristics within a community, and to identify what advantages might be associated with variants of social capital. The pursuit of the understanding of social capital has been convened within narrow disciplinary fields and has reduced the notion in definition, purpose, and utility. Much of the literature and past research has focused on approximations to identify social capital that are field-specific and representative of, at best, markers of social capital, rather than social capital itself. For this reason, this dissertation is concerned with developing a robust framework that has the potential to embrace the nature and extent of social capital across these disciplinary fields, while providing insight into the forms, influences, and trajectories of social capital. The utility of the Social Capital Framework that was developed for this dissertation was examined by transforming the Framework into a survey tool for administering in two communities to identify applicability and sensitivity for identifying the degree to which variants of social capital reside. The results showed that the Framework was able to distinguish the degree to which different forms of social capital existed, and how the social capital accumulates in relations to structural variables, in particular, gender. The Framework’s utility was not universal across all forms of social capital and showed that further enhancements are required, particularly, if it is to enable social capital to be attributed to forms of advantage. The results also identified areas where future research would be of value, particularly, in examining the trajectory of people’s forms of social capital.

This thesis explores claims that organic agriculture may be an empowering development strategy by investigating the impacts of conversion to organic farming systems on the lives of small-scale farmers in Cambodia. The thesis interrogates the diverse uses and abuses of the term =empowerment‘ in development rhetoric and argues for an empowerment model that is derived from farmers‘ self-defined concepts of development. This model was used to conduct a qualitative case study involving semistructured interviews and focus groups with members of organics initiatives in seven diverse Cambodian communities. Results indicate that many farmers in all communities felt that their most important objective was not only to achieve food security, but to be able to grow sufficient rice to feed their family. Farmers joined the organics initiatives primarily to improve their health and reduce the cost of farming inputs. As a result of joining the initiatives, all farmers (including both certified and non-certified organic farmers) felt they had improved their health and food security. Most farmers also increased incomes, created stronger family and community ties and felt they had more control over their livelihoods. These benefits were not, however, distributed equally amongst individuals or communities. Very poor and isolated farmers could not generally access benefits. The three main factors that determined the impact of the organics initiatives on farmer empowerment were identified as: the individual‘s level of resources, the strength of the farmer group, and the policies and values of the supporting organisation. The implications for future initiatives are, firstly, the tremendous potential for farmers and wider rural communities to benefit from organic agriculture as a development strategy. However, this study also shows that if organics is to be viable for low-resource people, it may be necessary to promote both resources and techniques in organics initiatives. Also, a focus on building strong relationships both within the farmers group and linkages with local and wider stakeholders may enhance long-term sustainability of organics initiatives.

As economies develop, novel products are created and markets for these products arise. Genetically modified food (GMF) is an example of such a novel product and provides economists with the opportunity to investigate an infant market. Of particular interest with GMF is the impact of consumer reactions on the market. The response of consumers to GMF and their willingness to pay for it has emerged as an important factor in the development of this technology. This research investigates these consumer responses. Prior research suggests that two aspects of consumer behaviour may be relevant for the GMF market. First, consumers may react differently to different types of GMF, so that some products are potentially more economically viable. Secondly, some consumers appear to prefer not having GMF at all. Consumer behaviour is often framed according to neoclassical economic theory. Consumer preferences over goods and the attributes of those goods are generally held to have certain properties. The aspects of consumers' reactions to GMF noted above, however, may be in conflict with two properties of preferences in neoclassical theory. First, preferences over food attributes are not separable, but may interact with each other. Secondly, some consumers may have preferences regarding GMF that are not continuous. As a result, aggregate impacts of introducing GMF may be difficult to measure, which raises a third issue for investigation, aggregation. Finally, an alternative model of consumer behaviour is bounded rationality, which theorises that choices may be discontinuous as a result of specific protocols. It also suggests that consumers seek to make good-enough choices, rather than attempting to maximise their satisfaction. Thus, optimisation or maximisation is the fourth issue considered in this thesis. In order to investigate these properties of consumers' preferences, a choice experiment survey was developed. The strength of a choice experiment for examining these issues is its focus on the impact of each product attribute on a respondent's choices. Thus, it may be possible to identify potentially discontinuous choice patterns and to identify choices affected by interactions between GM technology and other food attributes. Results from a neoclassical analysis of the survey data suggest that some consumers consider the type of benefit created with GM technology in making their choices. In addition, one-quarter to one-half of respondents may have had discontinuous preferences with respect to GMF. Reactions to GMF appear related to respondents' attitudes, but not to socio-economic or demographic descriptors. As a result, aggregate measures of the impact of GMF may not fully account for consumers' responses. A boundedly rational model also has reasonable goodness of fit, and may provide a different perspective on consumer behaviour. It is hoped that the results of this research provide a better understanding of consumer behaviour regarding GMF and, by extension, of the process of consumer adoption of novel products. It is further hoped that this attempt to incorporate choice protocols into discrete choice analysis will provide a useful example for further research.

International migration and development have been traditionally treated as separate policy portfolios; however, today the two are increasingly viewed as interlinked. While the development status of a country could determine migration flows, migration can, in turn, contribute positively to national development, including economic, social and cultural progress. Consequently, if migration is not well managed, it can pose development challenges to a country’s development and progress. Therefore, partnership through greater networking between countries of origin and destination is needed to fully utilise the development potential of migration. For Tuvalu, migration has remained a vital ingredient for economic development and more importantly, the welfare of its people. The implementation of New Zealand’s Pacific Access Category (PAC) scheme in 2002 offered for the first time a formal migration opportunity for permanent or long-term migration of Tuvaluans. The PAC scheme allows 75 Tuvaluans per year to apply for permanent residence to work and live in New Zealand, provided they meet the scheme’s conditions. The goal of this research is to investigate, more than five years after PAC’s implementation, the ways in which long-term migration of Tuvaluans, through the PAC scheme, has benefited Tuvalu. To give a broader perspective on the issues explored in this study, the views of Tuvaluan leaders, as significant players in traditional Tuvaluan society, are included, in addition to the perspective of migrants’ families in Tuvalu and the migrants themselves in New Zealand. Combining transnationalist and developmental approaches as a theoretical framework, this thesis explores how Tuvalu’s mobile and immobile populations, through articulation of transnationalism, enhance family welfare, and grassroots and national development. The eight weeks’ fieldwork in Tuvalu and Auckland demonstrated that the physical separation of Tuvaluans from one another through migration does not limit the richness of the interactions and connections between them. In fact, the existence of active networking between island community groups and other Tuvaluan associations in Auckland and in Tuvalu strengthens the Tuvaluan culture both abroad and at home, thus ensuring strong family and community coherence. Maintaining transnational networks and practices is identified as of great significance to grassroots and community-based development in Tuvalu. However, the benefits of long-term migration can only be sustained as long as island loyalty, or loto fenua, and family kinship stays intact across borders, and networking amongst families, communities and church remains active.

This thesis investigates abnormal trading volume around scheduled and unscheduled announcements. The research is an extension of Chae (2005), Journal of Finance, Vol 60, which tests corporate announcements in the US stock market. In this thesis, Australian stocks are used to establish whether market characteristics affect trading behaviour around announcements. In addition, I extend the traditional methodology to overcome possible shortcomings in the previous studies. This thesis also discusses how information asymmetry affects the abnormal trading volume on the announcement day. In contrast to earlier studies, I nd abnormal trading volume does not change before either scheduled or unscheduled announcements, but, as expected, increases on and after the scheduled and unscheduled announcements. Information asymmetry increases trading volumes when unscheduled announcements are made, but has no effect for scheduled announcements. I show that the failure to adjust for the correlation between corporate events, results in abnormal trading volumes being detected prior to announcements. Differences between the Australian and US results can not all be explained by methodological differences. It appears that the underlying dynamics of the Australian market are different; casting doubts on the ability to generalize market characteristics from US based studies on abnormal trading volumes.

Remittances by international migrants have become an important source of finance for livelihood development amongst the households in Fiji. This is substantiated by the country’s rising migrant stock as a result of unstable political environment and the increasing economic opportunities for skilled manpower. It has been noted that the flow of remittances to Fiji excelled the amount of other capital inflows such as foreign aid and foreign direct investment and have surpassed commodity export earnings in the recent years. This has made remittances the second largest foreign exchange earner in Fiji after tourism. This thesis examines the developmental impact of workers’ remittances in Fiji, particularly its impact on economic growth, financial sector development, welfare development of the recipient households and an examination of the sustainability of remittance flows. Using an extended neoclassical framework, the empirical evidence finds a positive impact of remittances on economic growth and financial sector development. The welfare development hypothesis is tested using the Household Income and Expenditure Survey (HIES) data. This is analyzed first, by examining the expenditure patterns of the remittance-recipient households, the poverty and inequality effects followed by an assessment of human capital development impact of remittances. The empirical results show that households which receive remittances do not only expend their remittance income on basic consumption but have other substantive uses such as that on education of children, housing and expenditure on durables and nondurables. The poverty and inequality reducing effects of remittances, employ two counterfactual methodologies to estimate first, what the poverty and inequality indicators would be in a scenario where remittances are treated as an exogenous addition to household income. Second, it tests the effect in a scenario without migration and remittances, which treats remittances as a substitute for migrants’ foregone earnings. The results show strong poverty reducing effects of remittances irrespective of the methodology used while the effects on income distribution are not unambiguous. The results obtained for the human capital development analysis indicate the positive role of remittances in providing education opportunities for children in the recipient households. In noting these positive effects of remittances, it must however be acknowledged that the flow of remittances has to be sustainable overtime for households to benefit from human development. From a survey of Fijian-New Zealander migrant households, this study examines the remittance-sustainability debate. The results suggest that a combination of factors such as income of migrants, acquisition of higher education prior to migration and the intention to inherit assets from families in Fiji contribute to continued flow of remittances. These results do not support the hypothesis of remittance decay amongst Fijian migrants in New Zealand but reflect a strong altruistic motive of remittances sent to households in Fiji as insurance against economic shocks. This highlights the importance of development policy in facilitating the flows of migrant remittances for the socio-economic progress of Fiji.
