Die Dissertation beschäftigt sich mit der Einordnung von Entgeltgenehmigungen des TKG 1996 in die vorhandenen Kategorien des Verwaltungsrechts und untersucht die Rückwirkungsmechanismen dieser. Anlass für die detaillierte Analyse war ein Streit um eine Rückwirkung der Entgeltgenehmigungen nach dem TKG 1996. Die im TKG 1996 enthaltene Normierung eines Genehmigungsvorbehaltes stellt sich als gravierende Einschränkung unternehmerischen Handelns dar, da der Zeitpunkt des Wirksamwerden der behördlichen Maßnahme erhebliche ökonomische Bedeutung für die Beteiligten hat. Die Rückwirkung von Verwaltungsakten wurde im Unterschied zur vergleichbaren Situation bei Rechtsvorschriften bislang kaum näher juristisch analysiert. Insbesondere das Wirtschaftsverwaltungsrecht weist jedoch zahlreiche Fälle auf, in denen dieses Problem auftritt und nicht nur aus dogmatischen Gründen, sondern auch im Hinblick auf die aus unterschiedlichen Wirksamkeitszeitpunkten resultierenden Kosten für die verschiedenen Beteiligten, bewältigt werden muss. Die vorliegende Darstellung analysiert die allgemeine (wirtschafts)verwaltungs- wie die spezielle telekommunikationsrechtliche Literatur und auch die wesentlichen Entscheidungen umfassend. Zunächst werden im ersten Teil der Arbeit die wesentlichen gemeinschaftsrechtlichen und nationalen Rechtsgrundlagen erörtert und die Entwicklung des europäischen und nationalen Telekommunikationsrechts dargestellt. Weiterhin widmet sich dieser Teil der näheren Untersuchung der Entgeltregulierungsverfahren des TKG 1996. Im zweiten und Hauptteil der Arbeit erfolgt die Einordnung der verschiedenen Entgeltgenehmigungen in die verwaltungsrechtlichen Kategorien der Verwaltungsakte und die Untersuchung der Wirkungen, insbesondere der Rückwirkung dieser. Vergleichend werden Rückwirkungsmechanismen verschiedener Rechtsakte in den unterschiedlichen Rechtsgebieten untersucht. Abschließend wird die Rückwirkung von Entgeltgenehmigungen geklärt und die Entwicklung der Verwaltungspraxis und Rechtsprechung zur dieser Frage dargestellt. Der abschließende Teil der Arbeit wirft einen Blick auf die Novellierung des deutschen Telekommunikationsrechts im Jahr 2004 und die dadurch aufgeworfenen Fragen zur Rückwirkung der Verwaltungsakte im Rahmen der Entgeltregulierung. Zwischenzeitlich ist die Rechtsfrage nach der Rückwirkung der Entgeltgenehmigungen nach dem TKG 1996 durch ein Entscheidung des Bundesverwaltungsgerichts beantwortet, jedoch wurden durch den Gesetzgeber bei der Novellierung des TKG im Jahr 2004 neue, andere Konstellationen geschaffen, für die vorliegende Untersuchung Hinweise zur Klärung geben kann. Die Arbeit bietet sich durch ihre grundlegende Fragestellung für parallele Rechtsfragen auch auf anderen Märkten, die einer staatlichen Entgeltregulierung unterliegen, als detaillierte Analyse an. Dies gilt für das Postrecht, ebenso wie für weitere Netzregulierungen in den Bereichen Strom, Gas und Eisenbahn.

This thesis deals with public procurement within Operational Programme Education for Competitiveness during the period 2007 2013. The introductory part of the thesis contains a brief description of Operational Programme Education for Competitiveness and its implementation into targets of regional politics. The following parts are dedicated to the public procurement in general and then in a specific envoronment of Operational Programme Education for Competitiveness. The fundamental part of the thesis illustrates process of supervision of the public contracts (ex-ante and ex-post), results of the checks and most frequent mistakes revealed during checks with a brief analysis of their causes and suggested steps to eliminate them in future. Next part of this thesis is aimed at ineligible expenditures caused by mistakes in public procurements. The final part contains a closer look at area of public procurement in the frame of current programming period 2014 and 2020.

This dissertation concentrates on the interplay between politics and financial markets using various empirical tools applied on historical financial statistics. The first essay examines the effect of stock transaction taxation on trading activity and asset prices, specifically focusing on the case of early 20th century Sweden. The main finding is that the tax substantially reduced trading as well as the level of asset prices. In the second essay, modern ex post historical writing is contrasted with the ex ante views of contemporaries which are estimated from historical price data. The specific case study is the events around World War II related to the Nordic countries and Germany. The comparisons point out considerable differences between the assessments of historical events in the ex post and ex ante approaches. The third essay is an empirical study of price controls on asset price movements and how these controls affect asset returns. The study finds that the controls have large significant effects which even may influence estimates of the long-run equity premium. Altogether, this raises concerns about the use of century-long series of asset returns without correcting for the impact of institutional variation and market constraints. Finally, the fourth essay examines the growth effects of international financial liberalization and integration using a large country- industry sample from the 1980s. The main result is that industries highly dependent on external financing do not experience higher value added growth in countries with liberalized financial markets. Liberalization does, however, increase the growth rates of both output and firm creation among externally dependent industries. These results are consistent both with increased competition and increased outsourcing. / <p>Diss. (sammanfattning) Stockholm : Handelshögskolan, 2003</p>

Several stakeholders in Nigeria’s oil and gas industry have emphasized the need for petroleum sector reforms in Nigeria. Canada is reputed to have one of the best oil and gas tax regimes in the world. This thesis argues that certain tax measures in Canada’s oil and gas industry have considerable potential for addressing certain industry inefficiencies in Nigeria’s petroleum sector. In developing this argument, this thesis gives an overview of oil and gas taxation in both jurisdictions and examines the possibility of transferring laws between Nigeria and Canada by exploring legal and tax comparative law theories. The thesis also examines the major challenges in Nigeria’s oil and gas industry and identifies viable areas in Canada’s oil and gas tax system which have the potential to address these challenges. Given the peculiarities of oil and gas taxation in each jurisdiction, this thesis suggests that the selected Canadian fiscal and administrative measures may require certain modifications in order to make these measures more suitable for Nigeria’s legal and tax system.

The introduction of PPPs in infrastructure provision has changed the way in which governments around the world now view infrastructure provision. However, the introduction of PPPs to deliver the needed infrastructure has benefited only a few companies. Most of these companies are the big construction firms that possess technological know-how and those that have the financial ability to execute large infrastructure projects. Although SMEs are important for employment creation, inequality and poverty reduction, the participation of SMEs in these PPP projects is very low. This is because PPP models in developing countries are based on those used in developed economies, and such models ignore the socio-economic problems facing developing countries. Therefore, this study argues that PPP projects in developing countries present an opportunity for growing the SME sectors in developing countries. It challenges the viewpoint of seeing infrastructure backlogs only as providing opportunities to big private sector companies and argues that infrastructure backlogs can be used by governments to reduce the triple challenges of unemployment, poverty and inequality by linking SMEs to PPP projects. The traditional PPP model that is being applied by many developing countries does not fully encourage the participation of SMEs in PPP projects, as most of the projects executed through this model are bundled into big projects that SMEs cannot execute due to a lack of technological know-how and weak balance sheets. The study therefore suggests different ways in which the participation of SMEs in PPP projects could be improved based on the results of the survey conducted for this study. The study then proposes an “innovative conceptual PPP model for sustainable SME development” that takes into account the needs for developing countries to create jobs, reduce poverty and inequality. It also takes into account all challenges for SMEs identified through the review of literature and the study survey. / Economics / D. Litt. et Phil. (Economics)

Syftet med studien är att presentera ett designkoncept för publika diskussioner på nätet med målet att uppnå djupare diskussioner och minska mängden information overload. Arbetet använder metoden Concept Driven Interaction Design (CDID) som går ut på att skapa ett designkoncept utifrån flera olika teorier som appliceras genom interaktionsdesign. Ett designkoncept innehåller tre delar: ett namn, ett syfte och huvudprinciper. CDID innehåller sju steg som arbetet är utformat efter: 1.      Concept Generation – Summeras i en tabell som jämför diskussioner i forum (med flera antagande) och diskussioner med hjälp av metoden Philosophy for Children (P4C), samt annan teori. 2.      Concept Exploration – Åtta olika designaspekter identifieras utifrån jämförelsetabellen. 3.      Internal Concept Critique – Designaspekterna jämförs med två snarlika diskussionsformat. 4.      Design of Artifacts – Designkoncept version 1 skapas. 5.      External Design Critique – Intervjuer utförs för att undersöka intervjupersonerna generella erfarenheter av online diskussioner, testar antagandena från jämförelsetabellen och ge direkt feedback på första versionen av designkonceptet. 6.      Concept Revisited – Ändringar görs baserat på intervjumaterial och direkt feedback. 7.      Concept Contextualization – Designkonceptet kopplas tillbaka till litteraturen. Studien resulterar i ett designkoncept kallat CoFramer och stödjer dessa huvudprinciper som ställs i kontrast till material som identifierats genom intervjuerna: Tabell 1: CoFramers huvudprinciper och faktorer från intervjuer om diskussioner på forum. CoFramers huvudprinciper | Från intervjuer om diskussioner på forum Strukturerad början och slut | Diskussion utan tydligt slut Begränsat antal deltagare | Stor mängd deltagare Minimum antal deltagare | Många inaktiva åskådare Explicita deltagare | Lite information om deltagare Gemensamma förutsättningar | Otydlighet kring deltagares förutsättningar Begränsad informationstäthet per inlägg | Långa inlägg och/eller snabba inlägg Den röda tråden och parallella trådar | Oftast parallella trådar Aktiv samtalsledare | Outredda missförstånd Studien indikerar på att CoFramer bör resultera i mer strukturerade diskussioner och som utsätter användaren för en lägre mängd information overload och mindre grounding cost jämfört med vad som vanligtvis uppstår i publika diskussioner online. / The focus of this essay is to develop a design concept for online public discussions with deep discussions and low information overload. The method used is Concept Driven Interaction Design (CDID) which involves constructing a design concept by applying a variety of theories in tangible interaction design. A design concept has three basic parts: a name, high-level goals and outlines generic principles. CDID includes seven steps which is used in this work: 1.      Concept Generation – Formatted into a table that compare forum discussion (with several hypothesis) compared to discussions with the method Philosophy for Children (P4C) and other theories. 2.      Concept Exploration – Eight distinct design aspects are identified from the comparison table. 3.      Internal Concept Critique – The design aspects are compared to three similar discussion formats. 4.      Design of Artifacts – Design concept version 1 is created. 5.      External Design Critique – Interviews are conducted to explore their general experience of online discussions, investigate the hypothesis from the comparison table and to seek direct feedback on the first draft of the design concept. 6.      Concept Revisited – Changes are made to the design concept based on the interview material and the direct feedback. 7.      Concept Contextualization – The design concept is related to the original literature. The result of the study is a design concept named CoFramer. CoFramer’s generic principles are summarized and contrasted against factors identified from the interview material in this table: Tabell 2: CoFramer’s generic principles and interviews about online discussions. CoFramer’s generic principles | From interview material on forum discussion Organized start and ending | Discussions without clear ending Limited number of participants | Large number of participants Minimum number of participants | Large number of inactive spectators Explicit participants | Low information about participants Common conditions | Vagueness in participants conditions Limited information density per post | Long posts and/or fast posts The red thread and parallel threads | Often parallel threads Active facilitator | Unresolved misunderstandings The study indicates that CoFramer would create more structured discussions with a lower amount of information overload and less grounding cost compared what normally arise in public online discussions.
