This research critically analyses and compares how the United Arab Emirates (UAE)1 Law and English and Welsh (EW) Law regulates obligations in a contract, for a thing that is to come into existence in the future, namely a construction contract. Uncertainty/speculation as to how an obligation is to be performed in UAE Law is termed gharar. The word that is synonymous with this terminology in EW Law is “risk”. The extent of gharar or ‘risk’ (these terms are used on an interchangeable basis in this thesis) in an obligation plays a fundamental role in the profitability of a construction contract. Where losses become unacceptable, particularly for the Contractor, a dispute will arise. These circumstances may be in conflict with UAE Law, which obligates parties to a contract to ensure circulation of wealth by maintaining the anticipated profit to be made from a contract. This analysis also reviews how the level of gharar or ‘risk’ can be increased by operation of two types of provision that are included in standard forms of construction contract such as the International Federation of Consulting Engineers, Geneva, Switzerland (FIDIC) Conditions of Contract for Construction for Building and Engineering Works Designed by the Employer 1st Ed. 1999 (FIDIC99). The first is a provision that releases the Employer from liability where the Contractor does not give timely notice of an Employer’s act of prevention. The second is a provision giving the Employer a discretion to act in an opportunistic manner, and exempt or limit his liability. It considers how FIDIC99 should be applied to control gharar or ‘risk’ in a positive way. It also identifies similarities between how UAE Law controls gharar and that of the notion of parties’ reasonable expectations in contract Law (herein referred to as parties’ expectations), and how relational contracts operate to ensure parties achieve their expectations.

Religious institutions have been tax-exempt from almost all taxes for more than two centuries. The two primary justifications used to protect this ‘status’ is the constitution and the concept that churches provide positive externalities that believers and non-believers all benefit from. This paper examines the relationship between religiosity and five socially important characteristics: high school graduation rate, a divorce rate, incidence of domestic violence, and levels of substance abuse and crime. I run multiple simple and full regressions across 207 counties in Texas. In four of the five analyses, religiosity has a strong statistically significant desirable impact. With the addition of control variables, other explanatory variables like median household income and number of divorces have coefficients with greater magnitude but the same statistical significance as that of religiosity.

Unrelated business enterprises have been an appropriate way for nonprofit organizations to generate income since the first income tax was enacted into law. The Internal Revenue Act of 1950 clarified this opportunity and enacted the Unrelated Business Income Tax to ensure that fair competition existed between nonprofits and for profit organizations. Nonprofit organizations conducting unrelated business enterprises are faced with a dilemma: it is legal for them to conduct such enterprises but if they do so they face potential litigation from for profit business for unfair competition and/or potential loss of tax-exempt status for operating outside of their exempt function. This dissertation traces the history and theory of tax-exempt status, the history of unrelated business enterprises, and how several states, including Oregon, have addressed the issue. It then explains two major pieces of litigation in Oregon in the 1980's, Southern Oregon State College and YMCA of Columbia-Willamette, then discusses the history of the media attention and legislative/bureaucratic action in the same period. Current litigation and media attention is then discussed. The paper then discusses two theoretical frameworks, Agenda Building and Advocacy Coalition, as a means to analyze the data. Following is a discussion of how the issues of unrelated business enterprises and unfair business competition can be handled by nonprofits and the changing criteria for tax-exempt status in Oregon. The dissertation concludes with the changing criteria for tax-exempt status in Oregon and fundamental philosophical and political issues yet to be decided. Included are recommendations such as a periodic review of tax-exempt status of nonprofits, the need for nonprofits to continually review their mission and exempt purpose, the need for nonprofits to maintain their relationships with the community they serve, and how nonprofits need to develop a self-governing program before government develops one for them.

Av Sveriges idag 300 000 aktiebolag är 80-85 procent mikrobolag med färre än 10 anställda och mindre än 3 miljoner i omsättning. Mikrobolagen har därför stor be-tydelse för svenskt näringsliv och samhällets utveckling. Förutsättningarna för dessa bolags tillväxt och utveckling bör av denna anledning främjas, vilket kräver att regelverken är anpassade till deras villkor. Revisionsplikten för små aktiebolag är en av de regelförenklingar som diskuteras, där nyttan och kostnaden för revision står i fokus. Syftet med uppsatsen är att beskriva hur ägarna till mikrobolag upplever revisionsplikten, hur de väljer att agera vid ett avskaffande, samt analysera bakomliggande orsaker. I denna uppsats används en kvantitativ metod då antal förekomster av visst agerande vill undersökas. Den empiriska studien är gjord i form av en webbenkät skickad till 200 mikrobolag i Jönköpings län. Resultaten visar att ägarna till mikrobolag upplever att de har störst nytta av revision jämfört med övriga intressenter, dock anses även stat och kommun ha stor nytta av revision. Vidare framkom att de vanligaste argumenten för revision är att den ses som ett kvitto eller kvalitetsstämpel. 74 procent av ägarna uppger att de skulle fortsätta revideras om revisionsplikten avskaffades, detta då nyttan upplevs vara större än kostnaden. Dock anser 68 procent att revision bör vara efterfrågebaserad istället för tvingande. Mikrobolagen upplever revisorns roll som övervägande granskande. Emellertid spelar även rådgivning en stor roll, då hela 89 procent av respondenterna anser att reglerna för mikrobolag är alltför komplexa och hjälp behövs från kompetent rådgivare. Sannolikheten att mikrobolagen skulle vända sig till en redovisningsbyrå istället för revisionsbyrå om plikten avskaffas är enligt 44 procent stor eller mycket stor. 13 procent skulle inte alls kunna tänka sig ett byte. Slutsatsen är att mikrobolagen upplever revision som positivt och att de skulle fortsätta revideras om plikten avskaffades, dock vill de flesta att revisionen ska vara frivillig och efterfrågebaserad, vilket för en del mikrobolag skulle innebära ett byte från att ha anlitat en revisionsbyrå för revisions- och rådgivningstjänster till att istället vända sig till en redovisningsbyrå. / Sweden has today 300 000 limited companies of which 80-85 percent are considered as micro companies with less than 10 employees and a yearly turnover not larger than 3 million SEK. The micro companies are therefore of great importance for Swedish business life and development of Swedish society. The requirements for these companies’ growth and development should therefore be supported, which require that regulations are adapted to their conditions. Statutory audit for small private limited companies is one of the simplifications of regulations that is discussed, where the benefits and costs of audit are in focus. The purpose of this thesis is to describe how owners of micro companies perceive statutory audit, to examine how they chose to act if it is abolished, and to analyze underlying causes. In this thesis a quantitative method was used since the numbers of occur-rences of certain actions were examined. The empirical study was constructed as a web based questionnaire sent to 200 micro companies in Jönköping County. The results show that owners of micro companies perceive greatest benefits from audit compared to other interested parties, however, the government and municipality also are considered as benefiting from audit. Further, the most common arguments pro audit are that audit is considered as a receipt or a quality guarantee. 74 percent of the owners state that they would continue to demand audit even if the statutory audit was abolished, since the benefits are perceived as greater than the costs. However, 68 percent believe that audit should be based on demand instead of being compulsory. The micro compa-nies experience the role of the auditor as mainly reviewing. Though, the role as adviser is also of great importance when as much as 89 percent of the respon-dents believe that small companies’ regulations are too complex and that help from a qualified advisor is needed. The probability that micro companies would turn to a firm of accountancy instead of a firm of audit if the obligation was abolished is according to 44 percent large or very large. 13 percent would not consider a change at all. The conclusion is that micro companies perceive audit as a positive service, and that they still would be reviewed if the obligation was abolished. Though, most of the companies want audit to be voluntary and based on demand, which to some micro companies would imply a change from consulting a firm of audit for accounting and consulting services, and instead turn to a firm of accountancy.

This dissertation follows a three-essay format. Each essay evaluates a different fiscal institution from a public administration perspective. In the first essay I examine whether state-funded property tax exemptions are effective in reducing the property taxes. This class of exemption is characterized by a grant from state to local governments that is intended to replace property tax revenue and lower property tax payments. Two separate theories of local fiscal behavior predict that that price effects and fiscal illusion will reduce the effectiveness of this type of tax relief. I test these predictions using panel regression analysis on county-level data from Georgia. I find that only two thirds of the revenue allocated to this program is actually used for tax relief. In the second essay I test a model of the property tax in which the levy is set to balance the difference between budgeted expenditures and expected receipts from all other revenue sources. This model demonstrates how the property tax can be used to offset unexpected changes to other revenues given a change in personal income. This model is contrasted with an alternative model in which expenditures are budgeted after expected total revenues have been determined. I will estimate both models for local governments in Georgia and test which more accurately describes local fiscal performance. I will also use both to predict changes to the property tax over a period of time and measure which model generated the more accurate forecast. Unlike the first two papers, which are quantitative analyses of fiscal data, this chapter is a case study of the contract city model of governance as implemented in the newly incorporated city of Sandy Springs, Georgia. I investigate whether the scope of outsourcing in contract cities creates additional challenges for city officials that manage contractor performance. I evaluate the incentive structures in the contract agreements that influence the principal-agent relationship using a textual analysis research method. I find that certain combinations of municipal functions in a single public-private partnership creates the potential for negative synergies to arise which would increase the difficulty of monitoring and managing the private partner.

Using Title IX of the Educational Amendments of 1972 and a review of the history of sport in the United States, this thesis provides a critical feminist analysis of how the legal system perpetuates and justifies sport as a male domain. The gender hierarchy in sport continues to be supported through the interpretation of the law meant to rectify gender disparities. The analysis of legal records in this thesis demonstrates that cultural and social beliefs regarding women and sport are evident in the construction of the law and impacts court rulings. Title IX and its subsequent interpretations and regulations, specifically, the Contact Sports Exemption, are manipulated in an unconstitutional manner reinforcing the traditionally male dominated institution of sport. This thesis argues that despite the nondiscrimination intent and purpose of Title IX, false assumptions about gender are perpetuated within the law and make gender equality in sport difficult, if not impossible.

Der Automobilsektor ist derzeit einer der wichtigsten Industriezweige in Europa. Ca. 2,2 Millionen Mitarbeiter sind direkt, weitere 9,8 Millionen indirekt darin beschäftigt (sechs Prozent aller Beschäftigten in Europa) und erwirtschaften mit einem Umsatz von ca. € 780 Milliarden im Jahr einen bedeutenden Teil des europäischen Bruttoinlandprodukts (BIP). Auch aus Sicht der Konsumenten ist das Auto für 80 % der Europäischen Haushalte, die ein Auto besitzen, aus dem täglichen Leben nicht mehr weg zu denken. Die europäischen Staaten beziehen ca. € 380 Milliarden ihrer Steuereinnahmen aus der Automobilindustrie. Damit haben sowohl Staaten, Konsumenten als auch die Automobilindustrie ein gewichtiges Interesse am Florieren der Branche. Die Schattenseite der Automobilindustrie sind die CO2-Emissionen, die mit 20 % (der Anteil lag 1970 bei 12 %) aller CO2-Emissionen in Europa einen wesentlichen Teil zum Klimawandel beitragen, Tendenz steigend. So haben im Lauf der vergangenen Jahre mehr und mehr Staaten ihre Besteuerung der Pkw explizit oder implizit nach Umweltstandards ausgerichtet. Damit soll das Autofahren verteuert oder eingeschränkt und / oder die Nutzung von schadstoffarmen Pkw gefördert werden. Neben den Klimaschutz verfolgt die Europäische Union (EU) das Ziel, einen einheitlichen europäischen Binnenmarkt zu schaffen. Durch den Mangel an verbindlichen EU-Richtlinien im Bezug auf Abgaben, haben die Gesetze, Steuern und Abgaben auf einzelstaatlicher und regionaler Ebene ein kaum mehr zu überschauendes Maß angenommen, da Im Rahmen des Subsidiaritätsprinzips die Mitgliedsländer weiterhin ihr Steuersystem überwiegend autonom gestalten, sofern dies im Einklang mit bestimmten europaweiten Vorgaben steht. Dies führt zu einem sehr heterogenen Steuersystem, das gerade im Bereich des Verkehrs bedeutende Markteffekte (z. B. höhere Zulassungszahlen für Diesel betriebene Pkw oder kürzere Haltedauern) nach sich zieht. Europaweit einheitlich sind lediglich Regelungen zu Wettbewerbsbeschränkungen. Es lassen sich nach wie vor viele Beispiele für Marktverzerrungen und die Heterogenität der Steuersysteme in Europa finden: Marktverzerrungen und Wettbewerbsbeschränkungen zeigen sich bei Fahrzeugpreisen, die in Europa stark variieren. Beispielsweise kosten in Dänemark Pkw bis zu 37 % weniger als in Deutschland. Diese Arbeit untersucht und vergleicht die Abgaben auf den Erwerb, den Besitz und die Nutzung von Pkw in den EU-Ländern sowie Norwegen und der Schweiz sowohl systematisch als auch quantitativ. Zur quantitativen Analyse wurde eine Datenbank mit den zur Steuerberechnung notwendigen Informationen erstellt. Darunter sind beispielswiese: Steuersätze und –tarife, Fahrzeugdaten, Kraftstoffpreise, Instandhaltungskosten, Versicherungsbeitrage, Wechselkurse und der durchschnittliche Wertverlust der Fahrzeuge. Darauf und auf bestimmten Annahmen basierend wurden die absoluten Abgaben für repräsentative Fahrzeuge in den verschiedenen Ländern berechnet. Besonderes Augenmerk gilt der CO2-orientierten Besteuerung, die in 17 Ländern (zumindest teilweise) eingeführt wurde. Diese Arbeit betrachtet auch andere, d. h. nicht fiskalische Maßnahmen der Europäischen Union zur CO2-Reduzierung, vergleicht diese mit alternativen Instrumenten, und analysiert die Wirkung unterschiedlicher Besteuerung auf den Pkw-Binnenmarkt, z. B. den Einfluss von Abgaben auf die europäischen Automobilpreise und damit auf Arbitrageeffekte. Es zeigt sich, dass die Besteuerung in Europa sowohl in der Abgabenhöhe als auch konzeptionell in der Vielzahl der Bemessungsgrundlagen und Steuertarife sehr heterogen ist und maßgeblich zu den sehr unterschiedlichen Gesamtkosten der Pkw-Nutzung beiträgt. Die relative Abgabenlast ist in einkommensstarken Ländern Westeuropas nicht hoch genug, um den Kraftstoffverbrauch spürbar zu reduzieren. Aus dem gleichen Grund ist von der CO2-orientierten Novellierung der deutschen Kfz-Steuer kein ausreichender Kaufanreiz zugunsten effizienterer Fahrzeuge zu erwarten. Die in der Vergangenheit von der Europäischen Union eingeführten Instrumente zur Reduzierung von CO2-Emissionen aus dem Straßenverkehr führten nicht zu den erwünschten Emissionsverringerungen. Die jüngste Maßnahme der Europäischen Union, den Automobilherstellern Emissionsgrenzen vorzuschreiben, ist weder effektiv noch effizient. Im letzten Jahrzehnt haben sich die Automobilpreise in Europa zwar etwas angeglichen. Dies liegt weniger an einer Angleichung in der Besteuerung als an der schrittweisen Liberalisierung des europäischen Automobilmarktes und den Novellierungen der Gruppenfreistellungsverordnung. / The automotive industry is currently one of the most important industries in Europe. Approximately 2.2 million people are directly employed in this industry, and an additional 9.8 million jobs indirectly depend on it. This represents 6 percent of all jobs in Europe. A significant amount of Europe’s gross domestic product is generated in this sector which produces a turnover of approximately € 780 billion per year. Governments, consumers and car manufacturers have a significant interest in a flourish automotive industry: 80 % of all European households own a car and rely on it in their day to day life and the European member states are collecting approximately € 380 billion in tax revenue from the automotive industry. One of the problems caused by the automotive sector are the carbon dioxide (CO2) emissions and their impact on the environment. 20 % of all CO2 emissions in Europe are currently caused by cars, being a major contributor to climate change. The contribution has increased from 12% in 1970 and is expected to grow even further in the future. Consequently, several countries recently introduced taxes that consider carbon emissions with the aim to reduce the use of cars, or to incentivise the use of more fuel efficient vehicles. The automotive sector is not only relevant for the European Union’s (EU) climate policy, but for its broader goal to ensure a functioning internal market with free movement of people, goods, services, and capital. However, the degree to which a free internal market can be achieved also depends on the homogeneity of the tax system throughout the EU. To date, taxes and other duties are still very heterogeneous across the EU, due to the lack of binding regulations and directives with respect to taxes – in accordance with the principle of subsidiarity embedded in the Maastricht treaty. These differences affect the automotive sector, for example in terms of demand for diesel cars, or the average number of years that a car is used. More importantly, market distortions can still be observed in the automotive sector: Heterogeneous tax systems lead to vastly different car prices within the EU, e.g. cars are up to 37% cheaper in Denmark than in Germany. This study compares and analyses - both quantitatively and qualitatively - taxes and duties on cars in connection with their purchase and registration, ownership and tenure as well as use. The analysis covers all 27 EU member countries, Switzerland and Norway. For the quantitative analysis, a software based database and simulation tool was developed. This tool contains all relevant data, such as tax rates, tax scales, car characteristics, fuel prices, car maintenance costs or depreciation rates. The simulation tool uses the data to calculate taxes and duties for a number of specific cars models (selected representatively covering all segments) for each of the 29 countries, relying on certain assumptions where necessary. The analysis focuses particularly on taxes introduced to reduce the CO2 emission of cars in the EU, namely CO2 based taxes of motor vehicles, which have been introduced in 17 of the 29 countries. This thesis also considers other, non fiscal measures of the EU that are designed to reduce CO2 emis¬sions of cars. These measures are subsequently analysed and compared to other instruments in order to understand the impact of different taxation models on the European internal car market, for example, with respect to car prices in the EU and hence potential for arbitrage. The thesis demonstrates that material differences in taxation of cars exist, both regarding the total amount of taxes levied in similar circumstances, but also regarding the underlying concepts and bases for assessment. This heterogeneity results in vastly different costs of purchasing, owning and driving a car. In the relatively wealthy countries in Western Europe, costs are not sufficiently high to have a notable impact on the consumption of fuel. This is also why the new German tax on car ownership, although based on the average fuel consumption, is not expected to create a significant incentive for consumers to buy more fuel efficient cars. Similarly, the EU measures to reduce CO2 emissions of car usage failed to deliver the desired outcomes. The most recent instrument of the EU, prescribing emission thresholds for car manufacturers, is neither effective nor efficient. The thesis also shows that during the last ten years car prices in the countries of Europe have converged. However, this is less due to the increasing similarities in taxation, but instead due to the gradual liberalisation of the European car market and the renewal of the block exemption for the motor vehicle sector.
