This study uses both basic and self-selection regression models to test three hypotheses about the effect of SFAS 87 disclosures on information asymmetry during 1985- 1987. Both types of models test the hypotheses after controlling for changes in the inventory holding and order processing costs of the spread, while the self-selection models also control for potential self-selection bias.

This thesis analyses and compares the performance, performance persistence and fund flows for UK equity unit trusts/OEICs and UK equity unit-linked personal pensions over the sample period January 1980 to December 2007. Unit-linked personal pension funds are an illiquid investment from the investor’s perspective since any invested capital is inaccessible until retirement whereas for unit trusts/OEICs capital invested can be withdrawn at any time. Since decreasing returns to scale from fund flows are the equilibrating mechanism in Berk and Green (2004) that results in no persistence in performance the illiquid nature of unit-linked personal pension funds should ensure more evidence of performance persistence in comparison to unit trusts/OEICs. I find significant evidence using performance ranked portfolio strategies that underlying portfolios that are only composed of unit-linked personal pension funds have greater performance persistence than unit-linked personal pension funds that have underlying portfolios that also include at least a unit trust/OEIC. This evidence is consistent with Berk and Green (2004) since the illiquid nature of personal pension funds results in an attenuated performance fund flow relationship restricting the equilibrating mechanism. However, there are anomalies in the performance persistence results in relation to Berk and Green (2004) but it could be due to the differential between the number of non-surviving unit trusts/OEICs and non-surviving unit-linked personal pension funds. I also find that the performance fund flow relationship based on abnormal returns from a Carhart four factor model for both UK equity unit trusts/OEICs and UK unit-linked personal pensions is convex but the performance fund flow relationship is more attenuated for the unit-linked personal pension funds. For the worst performing unit trusts/OEICs there are outflows on average whereas for unit-linked personal pensions there are fund inflows on average. For performance persistence tests conditional on underlying portfolio fund flows unit trusts/OEICs that have the worst performance but the lowest net fund flows in the ranking period have significantly greater subsequent performance in comparison to the unit trusts/OEICs that have the worst performance but the highest net fund flows in the ranking period. This empirical evidence provides support for Berk and Green (2004) but for the unit-linked personal pension funds the evidence is less convincing. There is very little evidence that UK equity unit-trusts/OEICs or UK equity unit-linked personal pensions produce abnormal returns. These results are robust across the single index (CAPM) model, the Fama and French three factor model and the Carhart four factor model for both conditional and unconditional models. There is also no evidence that unit trusts/OEICs or unit-linked personal pension funds can time the market. There is a significantly negative timing effect across unconditional factor models which becomes insignificant for the conditional models. There is also no evidence that unit trusts/OEICs have significantly different performance than unit-linked personal pension funds.

China is entering a new historical era that has as its demographic hallmark an ageing population. The fact that China is ageing before it becomes a modernised, wealthy country, presents serious challenges, one of the most direct and important of which relates to support for older members of society. This thesis concerns the way in which different factors affect intergenerational transfers from adult children to their old parents, with particular focus on living arrangements and parental income. The core question this thesis aims to address is: If public transfers increase, would this crowd out private transfers? The results of the estimated association between living arrangements and intergenerational transfers are also used to improve the robustness of the test of crowding-out effect. This study is based on empirical analyses of two waves of nationally representative datasets, covering adult individuals aged 60 and over from 20 provinces in urban and rural China. Living arrangements are vital to intergenerational transfers and welfare in old age, especially in China where the family-based support mechanism by which the young cared for the old was traditionally through coresidence. The descriptive statistics show that though coresidence is still the predominant living arrangement in rural areas, older Chinese people are increasingly less likely to co-reside with children. Such changes in living arrangements, however, do not leave older people isolated over time. Investigation of the determinants of older people’s coresidence decisions shows that older people with more financial or instrumental needs are more likely to live with children. Analysis of the determinants of parents’ living distance from children finds that in urban areas, old parents with higher pensions are more likely to live far away from children, although insignificant effects are found for rural samples. Finally, this study finds weak evidence that parents living far from children receive more intergenerational transfers. Overall, it has been found that family support, including intergenerational monetary transfers, is still prevalent in China; particularly in rural areas. Although a pattern of declining intergenerational transfers began to emerge during the period between 2000 and 2006, the family unit, and traditional family support, appear likely to remain an essential pillar of security in old age. Through the use of a variety of quantitative methodologies this thesis is able to provide robust estimates of how the increase in public programmes is influencing private transfers in China. Analysis of the factors that determine the incidence of receipt of transfers from children suggests that intergenerational transfers in China tend to target old parents that are in greater financial need. Moreover, the analysis of determinants of the size of transfer suggests that although altruism and exchange motives co-exist, the exchange motive dominates inter-generational transfers in urban China. This study does not find statistically significant estimates of transfer derivatives for older people in rural areas. The emerging pattern of support for older people indicates the pursuit of a new balance between formal and informal support. This thesis argues that a gradual increase in public transfers will not crowd out private transfers, and, in cities, may actually strengthen private transfers.

The three constituent chapters of this thesis tackle independent, self-contained research questions, all concerning welfare economics in general and its application to climate change policy in particular. Climate change is a policy problem for which the costs and benefits are distributed unequally across space and time, as well as one involving a high degree of uncertainty. Therefore, cost-benefit analysis of climate policy ought to be based on a welfare function that is sufficiently sophisticated to incorporate the three dimensions of aggregation: time, risk and space. Chapter 1 is an axiomatic treatment of a stylised model in which all three dimensions appear. The main result is a functional representation of the social welfare function for policy assessment in such situations. Chapter 2 is a numerical mitigation policy analysis. I modify William Nordhaus' RICE-2010 model by replacing his social welfare function with one that allows for different degrees of inequality aversion along the regional and inter-temporal dimension. I find that, holding the inter-temporal coefficient of inequality aversion fixed, performing the optimisation with a greater degree of regional inequality reduces the optimal carbon tax relative to treating the world as a single aggregate consumer. In Chapter 3 I analyse climate policy from the point of view of intergenerational transfers. I propose a system of transfers that allows future generations to compensate the current one for its mitigation effort and demonstrate the effects in an OLG model. When the marginal benefit to a - possibly distant - future generation is greater than the cost of compensating the current generation for its abatement effort, a Pareto improvement is possible by a combination of mitigation policy and transfer payments. I show that under very general assumptions the business-as-usual outcome is Pareto dominated by such policies and derive the conditions for the set of climate policies that are not dominated thus.

Thesis (MDF)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Pension funds are large institutional investors in South Africa and hold some of the highest levels of investment, relative to gross domestic product, in the world. The South African stock market is also the largest stock market in Africa. Research has shown that pension funds can play an important role in developing stock markets. This assignment investigated the impact that pension fund investment has had on the development of the South African stock market. This question is particularly relevant in the light of the changing domestic pension policy environment and the need to better develop stock markets in Southern Africa and globally to generate economic growth. The Johansen cointegration approach was applied to evaluate the impact of pension funds on the development of the South African stock market. Stock market development was measured by its depth or market capitalisation, liquidity and volatility. The analysis shows that South African pension funds have improved the liquidity and reduced the volatility of the stock market. Pension fund investment in shares increased market capitalisation, while market capitalisation was reduced when the prime lending rate was included as a control variable. Total pension fund investment decreased market capitalisation, probably through the impact of interest rates on interest-bearing assets held in the portfolio.

Defined Benefit (DB) state pension trust funds are an integral component of state finances and play a major role in the country’s labor and capital markets. The last decade though has seen a substantial growth in unfunded pension obligations and a seeming inability by states to make the contributions needed to cover funding shortfalls. When coupled with even larger unfunded retirement health benefits, the looming threat of insolvent state retirement systems pose both current and long-term fiscal challenges to state governments already struggling with the ongoing economic downturn and billions of dollars in budget deficits. The convergence of these factors have led states to undertake various reform strategies in an attempt to move their respective public pension plans towards a more sustainable funding path. Using an asset-liability framework to describe the DB plan funding structure and process, this dissertation advances the discussion over major pension reform efforts currently implemented or considered by states. I show analytically the link between various pension reform categories and specific DB plan funding components, and how this in turn, affects DB plan funding outcomes. From this analytical framework, I derive the study’s hypotheses on the relationship between DB plan reform-linked funding components and outcomes of interest. This study looks at three DB-plan reform-linked funding components: (1) plan member employee contributions, (2) plan employer contributions, and (3) retirement benefit payments. Four major funding outcomes are evaluated: (1) the employer contribution rate, (2) flow funding ratio, and (3) stock funding ratio, and (4) relative size of plan unfunded liability. Utilizing a unique panel dataset of 100 DB state retirement systems from 50 states covering a nine-year period of FY 2002 to 2010, I empirically test the following hypothesized funding relationships: (1) States as DB plan sponsors have underfunded their plans as indicated by their failure to meet annual employer funding requirements; and (2) Increasing the employee and employer contribution rate and reducing the cost of retirement benefits are associated with higher plan stock funding ratios and lower unfunded pension liabilities. Results from my fixed-effects (FE) panel regression analyses provide the clearest empirical evidence to date that state DB pension plan sponsors underfunded their required annual employer contributions. The financial condition of a state’s budget is also shown to have a significant effect on the amount states are able to contribute into their pension funds. I find empirical support for the crucial function of employer contributions in determining the overall funded status of state pension plans. This finding is further reinforced when I estimate plan stock funding ratios using a dynamic system GMM (sGMM) panel regression model. The results from static FE and dynamic sGMM models suggest no significant effect on overall plan funding levels from changes in the employee contribution rate or the average retirement benefit cost. Lastly, the results lend evidence to the significant influence of past funding levels on current funding levels. It is recommended that future empirical research account for the dynamic nature of public pension funding and related endogeneity issues. This dissertation concludes by discussing the implications of the empirical findings for policy makers seeking to improve the funded status of their respective state DB retirement systems.

Prior to the establishment of Aid to Dependent Children in 1935, states offered cash assistance to single mothers and their children through locally administered programs known as mothers' pensions. Since the first mothers' pension law was passed in 1911, the rank-ordering of states' generosity has been remarkably stable, shifting only after welfare reform in 1996. Prior research has neither documented nor explained this remarkable path dependence. In this dissertation, I argue that states' racial and ethnic composition and their state capacity, as measured in the 1930s before the federalization of cash assistance to single mothers, set states on particular trajectories. To see how this operated in practice, I conducted a case study of benefit levels in Massachusetts from 1913 to 1996. I found that a constellation of factors at the beginning of mothers' pensions--the lack of a legislated maximum benefit level, state involvement in funding, and a competent professional bureaucracy--set Massachusetts on a trajectory toward being a generous state. The early years of Aid of Dependent Children reinforced this trajectory, as benefit levels were consistently raised due to cost-of-living increases. Things began to change in the 1960s, however, as the caseload grew, the state experienced a fiscal crisis, and welfare rights activists campaigned for higher benefit levels. Welfare rights activism generated a backlash that resulted in a lack of public support for adequate benefit levels. Benefit levels declined until the early 1980s, when a strong economy, savvy advocates, and sympathetic elected officials combined to increase benefit levels. The early 1990s recession, which began in 1988 in Massachusetts, instigated another decrease in benefit levels. Ultimately, the case study showed that states may appear to have solid trajectories, but these trajectories are contested. Both raising and lowering benefit levels came up in the Massachusetts Legislature many times, and a fundamental change in Massachusetts' state capacity, such as permanently reduced fiscal resources, could have sent Massachusetts down a different path.

Approved for public release, distribution is unlimited / The defined benefit (DB) pension system that provides retirement security to 44.5 million Americans faces significant challenges. At the end of 2003, the system was underfunded by $350 billion, there were 82,696 fewer plans then during the system peak (in 1985), and the Pension Benefit Guaranty Corporation (PBGC) responsible for ensuring retirees receive their retirement benefits even after a plan terminates, reported a deficit of $11.49 billion. This thesis examines the challenges facing the DB pension plan system, beginning with an overview of the DB plan system, a review of the different plan types, the benefits received, and funding rules. Next, examining the PBGC, its purpose, its organization, and the role that it plays in the DB pension system. Followed by an identification of the challenges facing the pension plan system, and corporate America's frustrations with the system. Finally, the thesis presents some recent reform proposals, and provides corporate America's response to them. A changing workforce demanding leaner retirement options, plans that allow multiple career changes, provide beneficiaries with lump sum benefits, provide early vesting characteristics, and are easily understood, is challenging the future of the DB plan system. To survive the DB plan system must continue to change. / Lieutenant, United States Navy

Conventional post-conflict state-building models approach disarmament, demobilisation, and reintegration (DDR) programmes as a means for state actors to delegitimise non-state sources of power and centralise control over coercive power with the state. The programmes carry the promise of new lives for conflict actors and a new, modern and technocratic approach to the exercise of force; they are thus central to post-conflict transformation. However, this thesis calls into question the naturalisation of 'state' and 'conflict' actors in DDR models. Instead, it finds that DDR programmes create these categories and, in doing so, serve to mask and facilitate continuities in elite power. This thesis examines the case of Timor-Leste. In Timor-Leste, the country's new leaders - resistance actors cum state actors - have centralised legitimate power, while, at the same time, incorporated non-state, resistance-era networks and identities upon which their authority depends. The key technology through which this order has been established is a suite of reintegration programmes. In registering over a quarter of a million people and dispersing significant funds, this programme has emerged as a tool of governance. Again challenging the idea of a 'state' acting upon 'veterans', this thesis finds that these programmes constitute these identities. The act of defining non-state conflict actors who may no longer legitimately wield force also necessarily defines the category of state actors who may wield force. In asking what these programmes 'do,' this thesis rejects conventional readings of reintegration practices as security-driven or processes like registration as purely administrative challenges. As such, this study introduces a critical, new perspective on the political economy of post-conflict reintegration programmes. It supports its findings through a mixed methods approach, combining a robust, representative survey of over 220 former resistance members with ethnographic observation and 90 semi-structured elite interviews. This thesis is thus of relevance to those interested in DDR, conflict networks, and state-building.
