This paper is the first paper to present findings evaluating the consequences for employees of full and partial privatization using difference-in-differences combined with propensity score matching. We find: (1) partial privatization causes job creation in contrast to full privatization, which destroys jobs, (2) full privatization causes higher labor productivity improvement than partial privatization, (3) wage increases occur only in partially privatized firms and (4) there are small increases in labor quality investment in both cases. The results suggest partial privatization exploits market discipline to induce labor productivity whilst simultaneously providing welfare improvements for labor. This is the ‘win-win’ outcome predicted by the ‘helping hand’ theory of government. Our results suggest that governments are likely to gain wider support for a program of partial privatization rather than full privatization.

Indonesia consistently records higher levels of maternal mortality than other countries in Southeast Asia with its same level of socioeconomic development. I use a quasi-experimental, difference-in-differences approach to understand whether the role of information on the risk of death in childbirth can change women’s reproductive behaviors. In the first two chapters, I use the Maternal Mortality Module from the Demographic and Health Survey (DHS) in Indonesia to examine fertility and reproductive behavior responses to a sister’s death in childbirth. Fertility desires remain relatively unchanged but women take up behaviors in subsequent births that avert the risk of maternal death. In the last chapter, I combine population-representative data from the DHS with a village-level census (PODES) on service availability to understand how a village-level intervention to improve obstetric service use using a birth preparedness and complications readiness (BPCR) approach may improve obstetric service use. In this study, I find that the Desa Siaga intervention in Indonesia improved knowledge of the danger signs of complications among women but not among men relative to villages that did not get the program while controlling for endogenous program placement. More women got antenatal care due to the program but use of a skilled birth attendant and postpartum care did not change as a result of the intervention. Both genders report discussing a blood donor in preparation for delivery.

This paper deals with an elucidation of the theologico-political implications of Franz Rosenzweig’s relational conception of time in his work The Star of Redemption, the peculiarity of which expresses the concept “messianic difference”. Considered from the standpoint of the secularization debate, this messianic temporality offers a response to the verification of the Hegelian assembly of political philosophy and philosophy of history which, according to Rosenzweig, First World War represented. The consequent political disappointment experienced by the author of Hegel und der Staat led him to the pursuit of a Neues Denken determined by the ontological primacy of time as well as the unbreakable relationship which Rosenzweig established between “temporality” and “otherness”. Taking as terminus a quo the anthropological distinction between “personality” and “self”, i. e. between “ethics” and “metaethics”, that Rosenzweig presents in The Star, I will finally attempt to explore the various modes of temporalization that, depending on the relation to the temporalization of God and the world, are possible for the Rosenzweigian Self, as well as their related theologico-political aftermaths.

Detta arbete har gjorts med syftet att utvärdera sysselsättningseffekterna i svenska aktiebolag av införandet av RUT-avdraget. RUT-avdraget infördes 2007 och innebär att privatpersoner kan få göra skattereduktion för olika typer av hushållsarbeten. Datamaterialet som används i denna studie är bokföringsdata för alla Sveriges aktiebolag mellan 2000 – 2010, aggregerat till tresiffriga SNI-koder för alla de svenska kommunerna. Utifrån datamaterialet har RUT-avdragets sysselsättningseffekter analyserats med hjälp av en Difference-in-Differencemodell. Resultatet visar att RUT-avdraget gjort att 6930 nya arbeten har skapats i de svenska aktiebolag som ingår i RUT-sektorn. Detta innebär alltså att RUT-avdraget har haft en positiv effekt på sysselsättningen.

BACKGROUND: Death from acute coronary syndrome (ACS) is avoidable with early reperfusion therapy, however, evidence suggests inequity in women's ACS treatment within a number of international healthcare systems, when compared to men's. Research indicates mortality rates are higher in some age groups of women when compared to men for the sub-group of ACS known as ST-segment elevation myocardial infarction (STEMI). OBJECTIVE: To determine whether patient sex was associated with patterns of reperfusion treatment variation or increased inhospital mortality in patients with STEMI. METHODS: We undertook retrospective analyses on a government database for patients admitted to Victorian public hospitals with STEMI. Patients were categorised into two age groups: 18-64 and 65-84 years (inclusive), to determine whether patient sex and these age groups influenced treatment from 2005 to 2008 and mortality from 2005 to 2010. RESULTS: Both younger and older women received less frequent angioplasty with stent and more often received no reperfusion treatment than men in corresponding younger and older age groups (p=0.006 and p<0.001, respectively). Overall, women in both age groups were more likely to die inhospital than men from equivalent age groups with STEMI (p<0.001, both groups). CONCLUSIONS: Proportionately, both younger and older women received less interventional reperfusion therapy for STEMI than their male cohorts, and died more often during admission than men. Further research needs to be undertaken to verify the findings and causes, and guide future research to ensure application of evidence to treatment in patients with STEMI.

This study investigates the impact floods on property values using the hedonic property price approach and other relevant econometric techniques. The main objectives of this research are to investigate (1) the impact of the release of flood-risk information and the actual floods on property values (2) the temporal behaviour of negative impacts (3) the property submarket behaviour (4) the behaviour of flood affected vs flood non-affected areas and (5) the property market efficiency. The thesis expanded on the existing literature on natural disasters by applying a range of econometric techniques. Findings of this research are useful for policy decision-making which is aimed at minimizing the negative impacts of natural hazards on property markets. The thesis findings also provide a better framework for decision-making in the property insurance market. The methodological improvements that are made in the thesis will be invaluable for analysing the impacts of natural hazards elsewhere.

This thesis examines the relationship between initial loss events and the corporate governance and earnings management behaviour of these firms. This is done using four years of corporate governance information spanning the report of an initial loss for companies listed on the UK Stock Exchange. An industry- and sizematched control sample is used in a difference-in-difference analysis to isolate the impact of the initial loss event during the period. It is reported that, in general, an initial loss motivates an improvement in corporate governance in those loss firms where a relative weakness existed prior to the loss and that these changes mainly occur before the initial loss is announced. Firms with stronger (i.e. better quality) corporate governance have less need to alter it in response to the loss. It is also reported that initial loss firms use positive abnormal accruals in the year before the loss in an attempt to defer/avoid the loss — the weaker corporate governance the more likely is it that loss firms manage earnings in this manner. Abnormal accruals are also found to be predictive of an initial loss and when used as a conditioning variable, the quality of corporate governance is an important mitigating factor in this regard. Once the loss is reported, loss firms unwind these abnormal accruals although no evidence of big-bath behaviour is found. The extent to which these abnormal accruals are subsequently unwound are also found to be a function of both the quality of corporate governance as well as the severity of the initial loss.
