This dissertation contains two chapters on law and economics and one chapter on international trade. An important but under-researched issue for medical malpractice (med-mal) litigation is how physicians' previous medical malpractice experiences affect their behaviour. Using Florida data on closed med-mal claims, I find that if physicians have prior paid claims, their current litigation is resolved faster and is associated with less cost. Having a prior payout does not significantly predict the likelihood or the amount of the current payout. This suggests that ``learning'' occurs as a result of prior med-mal experience. As a theoretical motivation, I developed a dynamic version of the divergent expectations (DE) litigation model. The model predicts, consistent with the data, that physicians have a more realistic analysis of med-mal litigation if they have prior experience. Many robustness checks are carried out to test the results, including using a fixed effect framework, to which the results are robust. In the second chapter, we investigate the impact of ``duty to settle'' rule in predicting patterns in data. Prior models and studies of settlement ignore the insurer's ``duty to settle'' -- the obligation to settle within policy limits if it would be unreasonable to refuse a within-limits settlement offer. We incorporate the duty to settle into a structural model of settlement of medical malpractice claims, and then estimate the model using maximum likelihood methods applied to a Texas closed claims database. Both the data and our model predict: a mass of cases with a settlement demand by the plaintiff exactly at limits; a smaller but still sizeable mass of cases with settlement exactly at limits; very few above-limits payments by insureds; and when above-limits payments are made, they are often by insurers. The model does a reasonable job in predicting data moments, including fractions of cases settled at limits, settled above limits, and tried. Using the model in counterfactual analysis, we predict: (i) with no duty to settle, more cases will be tried; (ii) with strict insurer liability for not settling within limits, there will be fewer trials and more above limits payments by insurers; and (iii) the duty to settle will rarely cause insurers to pay more than the expected value of claims. The third chapter of this dissertation is on international trade. There is a well established literature on the impact of sovereign debt renegotiation on bilateral trade, including Rose (2005) among others. However, there is no study that disentangles impacts of renegotiation on the intensive and extensive margins, where the former is the trade volume of established bilateral trading relationships and the latter is the number of established relationships. This study employs the UNComTrade dataset and debt renegotiation data from the Paris Club for over 150 countries in order to address the impact of a debt renegotiation on the extensive margin of trade. This paper finds that bilateral trade volume declines following a sovereign debt renegotiation. The result is robust to the use of trade lags as instrumental variables to address endogeneity. Consistent with the trade literature, this study documents a negative impact of a debt renegotiation on the trade value using the Tobit approach in a fixed effect model, to appropriately handle censored data. Interestingly, a comparison between the marginal impacts of a debt renegotiation on the extensive and the intensive margins shows that the former effect has at least the same magnitude as the latter. / text

Contenders disputing electoral results in Sub-Saharan African countries often attribute defects in presidential electoral processes to the implementation of rules and procedures. Yet despite the considerable decision-making authority poll workers are entrusted with and the significance of the tasks performed by therm, scholars have not closely investigated poll workers'contributions to elections' management in Sub-Saharan Africa. Using principal-agent theory as the foundation, the purpose of this case study was to examine the challenges encountered in the organization of the presidential election in Togo, held on April 25, 2015, with a particular emphasis on poll workers' job performance. Research questions focused on whether poll workers in Togo have the ability and the resources necessary to carry out quality elections and the perceived effects of poll workers' performance on the integrity of the presidential electoral process. Data were obtained from interviews with 11 purposely selected poll workers and review of social media audio and video records of the election. These data were inductively coded and subjected to thematic analysis. A key finding was that deficiencies in poll workers' performance reflect a complex interplay of ill-conceived legal framework, lack of infrastructure, poor training, personal ineptitude, underfunding, partisanship, and tribalism. Further findings indicated that poll workers performing poorly resulted in long lines of voters, voter suppression, inaccuracies in vote counts, and delay in results announcement. Implications for positive social change include election practitionners' increased awareness that improving the quality of service delivery to voters on election day may foster confidence in and legitimacy of election results, seen as prerequisite to peaceful presidential elections in this part of the world.

Aim: The purpose of this study is to establish midwives’ perception of ethical and professional malpractices in labour units and to enhance the awareness of ethical behaviour and professional practice by midwives. Design: A qualitative, exploratory, descriptive and cross sectional design was followed to explore the midwives understanding of and experiences of ethical practice and professional malpractices in Labour Units of Tshwane, Gauteng Province. A non-probability purposive sampling was used to draw a sample from midwives with two or more years of experience working in Labour Units. Data collection: Individual in-depth interviews using open ended questions were used to collect data. Interviews were recorded using an audio tape recorder, which was later transcribed verbatim. Data collection was continuous until saturation was reached with the eight (n=8) participant. Findings: the results of the study revealed that midwives do understand the ethical code of conduct. However, due to challenges such as shortage of staff; shortage of material resources; non-compliance of midwives to policies and guidelines; fear of decision-making; and lack of management support, all this makes ethical conduct more challenging. It is hoped that the findings of this research will make contributions to midwifery training and practice. / Health Studies / M.A. (Health Studies)
