A key challenge confronting modern policymakers is to ensure that economic development is both socially just and environmentally sustainable. Toward that goal, effective government regulations require the accurate quantification of their associated costs and benefits. An extensive theoretical and empirical literature in economics has shown the benefits of government policies in addressing market failures and providing public goods. But few studies have credibly identified the social costs and distributional impacts of existing policies. My dissertation integrates new data and empirical methods from economics and earth sciences to investigate the social impacts of energy infrastructure and environmental policy. Chapter 1 uses the Three Gorges Dam in China as a natural experiment to provide the first evidence of the social and economic impacts of dam-induced inundation on population displacement and labor market reallocation. Chapter 2 examines the political economy implications of wind turbine construction on United States congressional elections. Chapter 3 employs original data from a large-scale survey to study the social benefits of environmental quality improvements. Overall, results from these papers inform future research on the social impacts of energy and environmental policy and highlight the importance of unbiased policy evaluations.

This study analyzes consumers' behavioral responsiveness to changes in price and policy regarding residential electricity consumption, using a hybrid method of econometric analyses and energy market simulations with the National Energy Modeling System (NEMS). First, this study estimates price elasticities of residential electricity demand with the most recent Residential Energy Consumption Survey (RECS) data, collected in 2005, employing a conventional econometric model and a discrete/continuous choice model. Prior to the NEMS experiments with price shocks and consumers' behavioral features, this study uses NEMS to examine how energy policies would affect changes in retail electricity price in the future. When climate policies are implemented nationally, electricity prices are estimated to increase by 17% in 2030 with a carbon cap and trade initiatives and by 4% with Renewable Electricity Standards (RES). The short-run elasticity of demand estimated from the 2005 RECS is found to be in a range of -0.81 ~ -0.66, which is more elastic than the current NEMS assumption of -0.15. The 2005 RECS dataset details information about American households' energy consumption. This rich source of micro-level data complements the existing econometric analysis based on time series data. Electricity price (either census-division average price or household average price), annual income and number of rooms are found to be three major determinants of the level of electricity consumption. The difference in short-run price elasticity leads to a difference in social welfare estimates of energy policies and energy market forecasts. This study suggests that the estimate of social welfare loss caused by electricity price increase is overestimated if the elasticity is assumed to be smaller than the actual responsiveness. Supposing that 1) the short-run elasticity of -0.66 reflects the actual consumers' responsiveness to price changes in the present and future and 2) retail electricity prices permanently increase by 10%, the welfare loss caused by the price increases would be estimated 0.9 billion dollars less than the current estimates with the elasticity of -0.15. This result suggests that if people are assumed to be more elastic to price signals, the time it takes for a policy to accomplish its goal could be shorter. In addition to assessing potential savings expected from consumers' behavioral changes with the concept of price elasticity of demand in neoclassical economic theory, this study reviews economic and non-economic theories about behavioral features of energy consumers and discusses how existing information programs could be improved.

Mixed communities have been largely developed by policy makers of western counties such as Australia, the United States and Western Europe. The debates of whether mixed communities could be the solution to the problems of poverty and place are still in examination. As most of the studies are concentrated on western context, this paper attempts to study the outcomes of living in a mixed community in Hong Kong. This study would be focused on assessing the outcomes of low income residents living in a mixed community in Hong Kong for exploring the possibility of urban planning and housing policy through the social mix policy. Though the idea of social mix is not the main concern in Hong Kong’s urban planning, the paper aims to find out whether living in a mixed community constitutes positive outcomes such as improving living environment, exploring social networks, seeking employment opportunities, role modeling and acquiring better livings in the future. A sample estate in Yau Ma Tei of Hong Kong would be chosen for case study to evaluate the outcomes of living in a mixed community. The study might provide hints for policymakers in considering of town planning and housing developments which towards the goal of reducing social problems such as poverty. There has no practical model or framework in development of policies allied with mixed communities. However, social integration and cohesion should be encouraged for promoting balanced neighbourhoods. / published_or_final_version / Housing Management / Master / Master of Housing Management

This work develops an opportunity for transgressive resistance to discursively formed structures of material and theoretical power and closure, based on a methodology of amateurism. The concept of amateurism draws heavily on the writing of Edward Said. This work synthesises Said with a broader corpus of postcolonial theory, following a theoretically postcolonial trajectory which applies the lessons from that referent to an engagement with traditional theoretical and cultural closure. The central thesis of the engagement follows a critique of strong ontology and vertical epistemology, or of expertise. Through an examination of health policy around birth, and sociological approaches to health, that critique is deployed to invigorate a new critical direction for the Left with a focus on subjectivity, social policy, social democracy and substantive citizenship. / Thesis (Ph.D.) - University of Adelaide, School of History and Politics, 2008

Prior 1994 South Africa had a fragmented health system designed along racial lines. One system was highly resourced and benefitted the few and the other was under-resourced and was for the black majority. Attempts to deal with these disparities did not fully address the inequities. The objective of the NHI is to address the inequalities by ensuring that all South African have access to affordable, quality healthcare services regardless of their socio-economic status. The majority of the participants do not understand the meaning and the implications of the national health insurance. Among the health professionals that were interviewed, there were no consultations before the implementation of the NHI. The health economists verbalized that it will be too expensive as the majority of citizens do not pay taxes. More roadshows need to be done to make communities aware of the planned strategy which will benefit all. / Health Studies

This dissertation consists of three papers at the intersection of social policy and immigration. The first paper analyzes the impact of immigrant welfare exclusion on government social spending at both an aggregate and specific social program level, using cross-national social expenditure panel data from 21 Organization for Economic Co-operation and Development (OECD) countries between 1990 and 2015 and taking advantage of the significant variation in welfare exclusivity across OECD countries by year. The second paper utilizes the variation in states’ response to the Affordable Care Act’s Medicaid expansion to investigate its effects on low-income immigrants’ inter-state mobility, specifically in-migration, and out-migration. Finally, the third paper utilizes data from the National Survey of Children’s Health to examine the effect of the announcement of the Trump administration’s revised Public Charge rule on insurance coverage and other health outcomes for children of immigrant parents.
