Magister Commercii - MCom / Three arguments are normally presented as rationale for the privatisation of state owned enterprises. The first relates to the problem of the financing of higher levels of public expenditure; the second is based on the viewpoint that private ownership is more efficient than public ownership; whilst the third claims that the losses of inefficient public enterprise are responsible for excessive budget deficits and other fiscal problems. Although empirical evidence proves that privatisation enhances economic efficiency, it negatively affects the affordability of and access to essential services, which may have serous consequences for poorer households. This happens through increased prices of essential services, such as electricity and telecommunication, as well as through loss of employment opportunities during and after privatisation. Many countries, also in Africa, implemented various types of privatisation programmes over the past two decades in order to decrease the relative size of governments and to improve efficient delivery of services. Towards the end the 1990’s and after the tragic genocide, Rwanda’s Government of National Unity also embarked on an ambitious restructuring programme of its state-owned enterprises. The main purpose of this study was to assess the likely impact of privatisation on poor households in developing countries. The report presents a general overview of the literature, with a specific focus on Brazil, Argentina and South Africa. It investigates the experiences of these countries and derives lessons that can be learnt. Finally it assesses the possible impact of the privatisation of essential service delivery on poor households in Rwanda. The main conclusion of the study is that governments should look beyond efficiency benefits of restructuring and focus on the overall opportunity cost of the privatisation of essential service delivery. The specific method of privatisation may determine the final social impact. The case studies also highlight the need for more research into the challenges facing the privatisation of essential service delivery. It is clear that any restructuring should be preceded by a thorough analysis of the likely impact on the poorer sections of the community. / South Africa

This thesis consists of a short introduction and three self-contained chapters. Chapter 1 develops a model of intra-household specialization and human capital formation for couples, taking into account of assortative sorting on income potentials in the marriage market. I assume people are matching on potential wage growth rates which differ across individuals and are realized through actual work experiences. The model is estimated by a simulated minimum distance estimator with PSID data from 1968 to 2011. I find there is strong positive assortative matching on wage growth rates, which helps explain the correlated wage growth residuals of married couples. If matching is switched to random, there will be more variation in household specialization arrangements and higher observed wage growth rates. The estimated elasticity of substitution between market goods and home production is approximately 0.37. Husband's time and wife's time turn out to be complements in the home production function. Chapter 2 studies a marriage market with two-sided information asymmetry in which the gains from marriage are stochastic. Contracts specify divisions of ex-post realized marital surplus. I first study a game in which one side of the matching market offers contracts, and then study a social planner's problem, finding necessary and sufficient conditions for a truthful direct revelation mechanism to achieve matching efficiency. These conditions become more stringent as the number of agents in the matching market increases. Chapter 3 examines the relationship between women's preference towards marriage and her marital outcomes. I propose using the mother's marital status as a proxy for her daughter's ex-ante preference towards marriage. Using 1980 and 2008 U.S. Census data, I estimate the impact of women's preference towards marriage and their educational attainments on their probability of getting married, and with Heckman correction, the impact on their husbands' earnings conditional on being married.

Australian immigration policy has traditionally been justified as a means to ensure national security and promote economic development. Neither of these rationales retains much contemporary force. A larger population is no longer regarded as critical to Australia's defensive capacity, and the quest for economic development, synonymous with aggregate growth, has been superseded by a concern about per capita growth performance. While humanitarian and cultural justifications for immigration have been advanced, they are either restricted in scope or contentious. Currently, the programme is operating on a large scale without a clear rationale. The purpose of this work is to investigate the economic consequences of immigration, and so consider whether the economic rationale may be recast in an alternative form. In this chapter, the existing literature is reviewed and a strategy for carrying the analysis further is outlined.
