<p>This thesis comprises three essays. The first two essays examine what inferences can be drawn about the structure of wages from the experiences of displaced workers using the Ontario Ministry of Labour Plant Closure Survey. The third essay examines the effect of unemployment benefits on household consumption during spells of unemployment, with a particular emphasis on durables purchases. It employs data from a second and new data source, the Canadian Out of Employment Panel.</p> <p>The first essay revisits the issue of what can be learned about wage tenure profiles from displaced worker data. The positive relationship between wages and tenure in cross section data is consistent with the accumulation of firm specific capital. Alternatively, it may be explained by unobserved heterogeniety across workers, or by endogenous mobility. Displaced worker data is quite helpful in correcting for the first possible bias, and less so for the second. The relationship between various estimation strategies in the literature is illustrated. Estimates that control for individual heterogeniety and endogenous mobility driven by systematic differences in the pay policies of firms are presented. In this data, 10 years of tenure appears to raise wages by about 7%.</p> <p>The second essay examines intra-industry wage differentials. Even after conditioning on a rich set of worker and job characteristics, firm of employment is a significant determinant of wages. Estimates that employ the longitudinal nature of data demonstrate that sorting of workers across firms by unobserved ability can explain about half of the observed differentials. Firm wage differentials are observed within narrow industries, consistent across broad occupational groups, and robust to conditioning on differences in the mix of skills or job characteristics. Further "high wage" firms exhibit high average tenures suggesting that positive wage premia are associated with reduced mobility. These observations imply that compensating wage differentials are also a poor candidate explanation for the observed differentials. The results are more consistent with models based on rents or some firm monopsony power. The results also raise questions about the interpretation of wage regressions which ignore firm heterogeneity, and about the sources of wages losses among displaced workers.</p> <p> The final essay examines how households smooth consumption over the income losses due to an unemployment spell. A model of "internal capital markets" is proposed, which suggests that households adjust the timing of the replacement of small durables to income flows. The plausibility of this model is investigated empirically, using a series of program changes in the Canadian unemployment insurance scheme for exogenous variation in transitory income. The data are consistent with the predictions of the "internal capital markets model" while rejecting both a standard life cycle model and a "rule of thumb" model of household expenditure patterns.</p> / Thesis / Doctor of Philosophy (PhD)

Yes / The study analyses approaches to the management of two projects within the regeneration portfolio of a large UK metropolitan council. Developing a theoretical framework drawing both from mainstream project methodologies and international development, the study highlights a number of key issues which need to be addressed, including entrepreneurship, participation, stakeholder buy-in, project lifecycles and benefit management. Key lessons emerging from the study include the need to foster entrepreneurship within the controlled environment of the project and the importance of setting programme targets which are appropriately orientated to harness the interdependent nature of benefits of regeneration projects in the public sector. / None

This research presents a new environmental justice assessment toolkit, the Equitable Environmental Justice Assessment Toolkit 2016 (EEJAT 2016). The purpose of this toolkit is to enable urban planners to more effectively measure whether environmental justice populations (low-income, non-white, Limited English proficiency, disabled, or elderly persons) are disproportionately burdened by long-range transportation plans. This toolkit is based on the concept that effective assessment of environmental justice (EJ) in transportation planning requires assessment frameworks that methodologically unify three sometimes divergent interests: those of federal and state bodies enforcing EJ assessment requirements, those of metropolitan planners who face capacity constraints and need guidance on how to conduct these assessments, and, most importantly, those of the protected populations themselves. This thesis involved analysis of current requirements, exploration of existing environmental justice assessment tools, case studies, decision theory, and principles of equity, and stakeholder engagement through surveys, interviews, and public meetings, all towards the development of the toolkit designed for the Roanoke Valley Transportation Planning Organization (RVTPO)'s Constrained Long-range Multimodal Transportation Plan 2040 (CLRMTP 2040) released in 2016. The resulting toolkit is a multi-step framework. The first step is a GIS map-based EJ Index, structured by normalized population distributions for each EJ demographic, and mapped by block group compared to regional (MPO) averages. This z-score based mapping was done in lieu of Roanoke's former linear model in effort to more systematically compare effects, and to more accurately represent the data, and by extension, the people. Second, the Community Profile expands upon the EJ Index to include documentation of community elements and social and economic systematic injustices in the area. Next, a Benefits and Burdens matrix guides planners to an appropriate model or method of assessment for each EJ effect for the project at hand, based on project scale and type, data availability, and skillsets of the assessor. The results of these assessments of each EJ effect are compiled for an overall Project Impact Assessment. Checks on assessor bias based on stakeholder feedback and decision theory are incorporated into this Project Impact Assessment. Cumulatively, the toolkit is designed to incorporate equity as a defining element of both processes and outcomes, to be flexible in order to be applicable to multiple projects, and to be usable by practitioners. / Master of Urban and Regional Planning

Rear-end collisions in which the leading vehicle was stationary prior to impact and at least one vehicle was towed from the crash site represent 18% of all yearly crashes in the United States. Forward Collision Avoidance Systems (FCASs) are becoming increasingly available in production vehicles and have a great potential for preventing or mitigating rear-end collisions. The objective of this study was to compare the effectiveness of five crash avoidance algorithms that are similar in design to systems found on production vehicles of model year 2011. To predict the effectiveness of each algorithm, this study simulated a representative sample of rear-end collisions as if the striking vehicle was equipped with each FCAS. In 2011, the ADAC (Allgemeiner Deutscher Automobil-Club e.V) published a test report comparing advanced emergency braking systems. The ADAC tested production vehicles of model year 2011 made by Audi, BMW, Infiniti, Volvo, and VW. The ADAC test results were used in conjunction with video evidence and owner's manual information to develop mathematical models of five different FCASs. The systems had combinations of Forward Collision Warning (FCW), Assisted Braking (AB), and Autonomous Emergency Braking (AEB). The effectiveness of each modeled system was measured by its ability to prevent collisions or reduce the collision severity of reconstructed crashes. In this study, 977 rear-end crashes that occurred from 1993 to 2008 were mathematically reconstructed. These crashes were investigated as part of NHTSA's National Automotive Sampling System, Crashworthiness Data System (NASS/CDS). These crashes represent almost 800,000 crashes during that time period in which the struck vehicle was stationary. Part of the NASS/CDS investigation was to reconstruct the vehicle change in velocity during impact, ∆V. Using energy and Newtonian based methods, the ∆V in each crash was calculated as if the vehicle was equipped with each modeled FCAS. Using the predicted reduction in crash ∆V, the expected reduction in the number of moderately-to-fatally injured (MAIS2+) drivers was predicted. This study estimates that the most effective FCAS model was the Volvo algorithm which could potentially prevent between 79% and 92% of the crashes simulated in this study and between 76% and 94% of associated driver injuries. This study estimates that the BMW algorithm would prevent the fewest number of crashes (between 11% and 14%), but would provide admirable benefits to driver safety by preventing between 21% and 25% of driver injuries. The VW algorithm would be the least effective at preventing driver injuries if the system were to be implemented across the U.S. fleet. This algorithm offers a 19% reduction in crashes, but only prevents 15% of driver injuries. This study introduces and demonstrates a unique method of comparing potential benefits of competing FCAS algorithms. This method could be particularly useful to system designers for comparing the expected effects of design decisions on safety performance. This method could also be useful to government officials who wish to evaluate the effectiveness of FCASs. / Master of Science

No / After more than a decade of comprehensive research work in the area of electronic government (e-government), no attempt has yet been made to undertake a systematic literature review on the costs, opportunities, benefits and risks that influence the implementation of e-government. This is particularly significant given the various related challenges that governments have faced over the years when implementing e-government initiatives. Hence, the aim of this paper is to undertake a comprehensive analysis of relevant literature addressing these issues using a systematic review of 132 studies identified from the Scopus online database and Google Scholar together with a manual review of relevant papers from journals dedicated to electronic government research such as Electronic Government, an International Journal (EGIJ), International Journal of Electronic Government Research (IJEGR) and Transforming Government: People, Process, and Policy (TGPPP). The overall review indicated that although a large number of papers discuss costs, opportunities, benefits and risks, treatment of these issues have tended to be superficial. Moreover, there is a lack of empirical studies which can statistically evaluate the performance of these constructs in relation to the various e-government systems. Therefore, this research would help governments to better analyse the impact of costs, opportunities, benefits and risks on the success of e-government systems and its pre-adoption from an implementation perspective.
