Thesis advisor: Uzi Segal / This dissertation consists of three chapters analyzing preferences for randomization in social choice problems. The first two chapters are related and in the fields of distributive justice and social choice. They concern allocation of an indivisible good in social choice problems where efficiency is at odds with equality. The last chapter addresses a social choice problem from an individual's perspective using decision theoretical analysis. In this dissertation I demonstrate why randomization may be an attractive policy in social choice problems and demonstrate how individuals may have preferences over the precise method of randomization. The first chapter is titled "Live and Let Die." This paper discusses how to allocate an indivisible good by social lottery when agents have asymmetric claims. Intuition suggests that there may exist agents who should receive zero probability in the optimal social lottery. In such a case, I say that these agents have weak claims to the good. This paper uses a running example of allocating an indivisible medical treatment to individuals with different survival rates and reactions to the treatment in order to provide conditions for consistency of weak claims. As such, I develop two related assumptions on a social planner's preferences over lotteries. The first -- survival rate scaling -- states that if an individual has a weak claim, then his claim is also weak when survival rates increase proportionally. The second -- independence of weak claims -- states that if an individual has a weak claim, then his removal does not affect others' probabilities of receiving the treatment. These assumptions imply that a compatible social welfare function must exhibit constant elasticity of substitution, which results in potentially-degenerate weighted lotteries. The second chapter is titled "Why is Six Afraid of Seven? Bringing the "Numbers" to Economics." This chapter discusses the numbers problem: the question of if the numbers of people involved should be used to determine whether to help certain people or to help certain other people. I discuss the main solutions that have been proposed: flipping a coin, saving the greater number, and proportionally weighted lotteries. Using the economic tools of social choice, I then show how the model of the previous chapter, "Live and Let Die," can be extended to address numbers problems and compare the implications of prominent social welfare functions for numbers problems. I argue that potentially-degenerate weighted lotteries can assuage the main concerns discussed in the literature and I show that both the Nash product social welfare function as well as constant elasticity of substitution (CES) social welfare functions are compatible with this solution. Finally, I discuss a related problem known as "probability cases," in which individuals differ in survival chances rather than numbers of individuals at risk. When the model is extended to allow for both asymmetries in survival chances and numbers of individuals in groups, CES results in potentially-degenerate weighted lotteries whereas Nash product does not. The third chapter is titled "All Probabilities are Equal, but Some Probabilities are More Equal than Others," which is joint work with Professor Uzi Segal of the Economics Department at Boston College and Professor Shlomo Naeh of the Departments of Talmud and Jewish Thought at The Hebrew University of Jerusalem. In this chapter we compare preferences for different procedures of selecting people randomly. A common procedure for selecting people is to have them draw balls from an urn in turn. Modern and ancient stories (for example, by Graham Greene and the Talmud) suggest that such a lottery may not be viewed by the individuals as "fair.'' In this paper, we compare this procedure with several alternatives. These procedures give all individuals equal chance of being selected, but have different structures. We analyze these procedures as multi-stage lotteries. In line with previous literature, our analysis is based on the observation that multi-stage lotteries are not considered indifferent to their probabilistic one-stage representations. As such, we use a non-expected utility model to understand the preferences of risk-averse individuals over these procedures and show that they may be not indifferent between them. / Thesis (PhD) — Boston College, 2020. / Submitted to: Boston College.

Magister Commercii (Industrial Psychology) - MCom(IPS) / As local textile manufacturing come under pressure from global competition, the competitive advantage of organisations in this sector have become an important research topic. As a key input in the manufacturing process, human resources can either be a burdensome cost or a source of competitive advantage for organisations in the textile industry. The effectiveness of human resources depends to a large extend on the ability of organisations to keep them motivated and productive.

Tanzania’s natural resources are national resources for the benefit of all Tanzanian citizens (The Arusha Declaration, 1967). The liberalization of the Mining Industry in the mid-1990s sparked hope in the country that the socio-economic status of all citizens across the nation would improve as a result of the mineral resource revenues obtained by the Government of Tanzania. Contemporary literature on mining in Tanzania has mostly riveted on issues surrounding a triangular relationship between the mining girdle and its population, foreign mining companies, and the Government of Tanzania. Hardly any attention has been given to the non-mining rural districts where the poor majority reside. This qualitative study using a phenomenological approach explored the shared experiences of citizens living in non-mining rural districts and their ascribed meanings of inequitable distributive realities in mineral resource revenues in Tanzania. The study employed the theories of relative deprivation and human needs for the theoretical framework. Study findings revealed seven core essences: socio-economic insecurity, inequity and injustice, communication and trust, investment and technology, moral leadership and human capital, growth and a culture of dependency. Understanding these essences should help determine policies and practices that promote equitable distribution of not only mineral resource wealth but also in other types of natural resource wealth found in the country; allowing for a true/win-win tri-partnership relationship involving all stake-holders: Tanzanian citizens, foreign investors, and the Government of Tanzania.

What does it mean to act morally? This research is part of normative ethics, which studies the formation of moral judgments and whether such judgments are able to motivate people to act in accordance with them. The gap between the dimension of the common good and the private life of each citizen has led to questioning whether there are moral norms whose content may constitute, per se, a sufficient reason for action. More specifically, when a norm, collectively chosen and shared, succeeds in self-imposing without any intervention of external authority.The interest for this theme arises from the urgency of defining conditions under which a group of interdependent agents, can organize themselves to obtain long-term collective benefits, find in collective action, a motivation, a commitment and a responsibility that decrease the temptation of opportunistic behaviour in distribution contexts. The main goal of this inquiry is trying to propose a normative solution of a problem of distributive justice in the following terms of: how can a norm generate a motivational causal force that induces compliance with what it asserts, in contexts where selfish rather than prosocial behaviour would be expected? This problem, approached from different perspectives, economic, psychological, sociological, also requires a philosophical reflection. Within this framework, the issue of compliance might be reread as a motivational problem: thus, the aim of this thesis would be to try to clarify the relationship between an impartial ethical point of view and what kind of real motivations people have to act in accordance with some specific ethical principles – namely, what reasons people have for acting in alignment with principles of distributive justice. Thus, the dissertation provides evidence from laboratory experiments that supports John Rawls’s Kantian constructivism as a method that allows subjects to evaluate different distribution criteria in production situations, making them reach an agreement on the liberal egalitarian principle. The Rawlsian method would rationally justify the ex-ante collective choice on that principle and it gives real motivations to comply ex-post, as it provides the conditions for creating a rationally justified joint commitment.

The issues surrounding the distribution and management of ecosystem resources in local communities in the face of climate change have never been more relevant. This qualitative study seeks to explore the understanding and implications surrounding environmental justice in local communities in the framework of environmental courses provided by organization “A” in northern Tanzania. The environmental justice indicator framework served as a conceptual framework to analyze the stakeholders' understanding and the local communities' experience surrounding different dimensions of environmental justice. Focus group discussions and semi-structured interviews were carried out with a total of 25 participants for data collection and analysis. A thematic analysis methodology provided several findings related to the contrast in substantive, distributive and procedural justices in relation to the environmental courses provided by the organization “A” and the local authorities. The study highlights the dynamics of access, power and control and the implications of intersectionality in relation to the distribution of ecosystem resources in the targeted rural communities. Concludingly, the research study highlights the need for more advocacy, coordination and efforts from the stakeholders, local authorities and local communities in achieving environmental justice for everyone.
