Abstract: We consider a model of commercial television market, where private broadcasters coexist with a public television broadcaster. Assuming that the public TV station follows a policy of Ramsey pricing whereas the private stations are profit maximizers, we consider the equilibria in this market and compare with a situation where the public station is privatized and acts as another private TV broadcaster. A closer scrutiny of the market for commercial television leads to a distinction between target rating points, which are the prime unit of account in TV advertising, and net coverage, which is the final goal of advertisers. Working with net coverage as the fundamental concept, we exploit the models of competition between public and private price and quantity in order to show that privatization of the public TV station entails a welfare loss and results in TV advertising becoming more expensive. Keywords: TV broadcasting, imperfect competition, Ramsey pricing, welfare comparison. JEL classification: L11, L82, L33 URI: http://hdl.handle.net/10398/7501 Files in this item: 1

Abstract: This paper proposes and analyses a model of start-up investment. Innovative entrepreneurs are commercially inexperienced and can benefit from venture capital support. Only part of them succeed in matching with a venture capitalist while the rest must resort to standard bank finance. We consider a number of policies to promote entrepreneurship and venture capital backed innovation. JEL Classification: D82, G24, G28, H24.

Abstract: In recent years, venture capital has become an important source for nancing young entrepreneurial rms. Given the apparently more innovative nature and extra value added of venture capital backed rms compared to other firms, policy makers have taken an increasing interest in an active venture capital industry. We explore how selected policy instruments determine the incentives of individuals to start up new rms and of venture capitalists to nance and advise them, and how policy thereby influences the size and nature of the industry and how it aspects aggregate welfare. We examine the impact of wage and corporate income taxes as well as capital gains taxes and start-up capital subsidies on the volume and quality of venture capital backed entrepreneurship.

Abstract: Offentlige forvaltninger verden over har været præget af voldsomme reformbølger de seneste 20-30 år, og den private sektor er i stigende grad blevet inddraget i den offentlige serviceproduktion. Privatiseringer og udliciteringer kendetegnede således forvaltningspolitikken i mange vestlige lande op gennem 1980erne og 1990erne. De mange reformtiltag er i forvaltningslitteraturen kendt under betegnelsen New Public Management. En af de senere udviklinger i den moderne forvaltningshistorie er fremkomsten af offentlig-private partnerskaber (OPP). OPP har i dag fået en lignende udbredelse som de tidligere privatiserings- og udliciteringstendenser. De fleste vestlige landeforvaltninger har således forsøgt sig med OPP, og i forvaltningslitteraturen har antallet af publiceringer om emnet været hastigvoksende de seneste cirka 10 år. Trods den store udbredelse, i såvel teori som praksis, skorter der imidlertid med klassifikationer, endsige definitioner af OPP begrebet. Denne afhandling har to centrale formål. Det ene er at afdække OPP begrebets mangetydige betydninger. Det gøres ved at kortlægge hvordan begrebet bliver anvendt i den internationale forvaltningslitteratur. Analysen viser at begrebets grænser er slørede, og at betegnelsen OPP bliver anvendt om en mangfoldighed af offentlig-private samarbejdsformer dækkende over uformaliserede netværksbaserede relationer såvel som stærkt formaliserede kontraktstrukturer. På baggrund af analysen inddeles forvaltningslitteraturen i en række strømninger. Dermed skabes et overblik over feltet som ikke eksisterede forud for analysen. Denne del af analysen munder endvidere ud i en ny måde at klassificere og definere forskellige typer OPP på. OPP er et relativt ungt forskningsfelt. En markant barriere for udviklingen af feltet har været manglen på anerkendte klassificeringer/definitioner. Begrebsdefinitioner er en forudsætning for teoriudvikling. Ved at afdække OPP begrebets mangetydige betydninger, og ved at udvikle nye måder at klassificere og definere OPP på bidrager denne analyse væsentligt til den fremtidige teoriudvikling om OPP. Afhandlingens andet formål er at afdække hvad der kendetegner samarbejdsrelationerne i idriftsatte OPP-projekter. Det er en udbredt opfattelse blandt praktikere såvel som forskere at OPP bebuder noget kvalitativt nyt relativt til de fordums tiders privatiseringer og udliciteringer. Der findes således en udbredt teoretisk diskurs om at OPP indebærer tætte og tillidsbaserede samarbejdsrelationer, dialog og fokus på processer frem for output. På trods af sådanne udbredte forventninger og antagelser om samarbejdsformens karakter, så er der forbavsende få systematiske empiriske studier af hvordan samarbejdsrelationerne ser ud i praksis. Ved empirisk at kortlægge samarbejdets karakter i fem britiske OPP-projekter udfylder afhandlingen derfor et vigtigt hul i den internationale forvaltningslitteratur. Analysen bidrager til litteraturen på to centrale måder. Den viser, for det første, at forventningerne om kvalitativt anderledes samarbejdsrelationer ikke bliver indfriet i flertallet af de analyserede cases. Det forventede skift fra hierarkiske, kontrolorienterede principal-agent relationer mod fladere, tillidsbaserede principalprincipal relationer ses ikke i praksis. For det andet ses der dog alligevel stor variation i den måde hvorpå samarbejdet udmønter sig i de forskellige cases. Den ene case udviser således mange af de førnævnte samarbejdskarakteristika som typisk bliver kædet sammen med OPP. Analyseresultatet peger på, at samarbejdsrelationernes kan udmøntes væsensforskelligt indenfor den samme type kontraktstrukturer. Dette peger videre på, at formelle strukturer kun giver en begrænset indsigt i samarbejdets karakter. For at få en dybere forståelse af OPP, er det derfor nødvendigt at gå bagom kontrakten og analysere hvordan samarbejdsformen udspiller sig i praksis. Der identificeres endvidere en sammenhæng mellem samarbejdspraksis og partnerskabsperformance. De cases som involverer de mest tillidsbaserede og tætte relationer ser samtidig ud til at være de cases, der præsterer bedst. Analyseresultaterne har implikationer for OPP litteraturen og ledelsesmæssige implikationer. For det første giver resultaterne anledning til at revidere den eksisterende teoretiske diskurs om OPP. Der er en tendens i litteraturen til at forbinde bestemte samarbejdsstrukturer med bestemte typer samarbejdsprocesser. Resultaterne her indikerer at disse to dimensioner ikke følger hinanden. Dernæst peger resultaterne på at ressourcer og ledelsesmæssig opmærksomhed med fordel kan rettes mod de løbende samarbejdsprocesser, da dette kan få betydning for samarbejdets udfald.

An international analysis - from a legal and economic perspectiveAndersen, Henrik; Cao, Fuguo; Tvarnø, Christina D.; Wang, Ping (Nottingham, 2010)[More information][Less information]
Abstract: This book provides a legal, economic and policy analysis of Public Private Partnerships. It is designed as a text for students at university level, but also for lawyers, procurement officials and policy-makers. The book consists of an EU, a WTO and a Chinese legal perspective. As explained on the cover page, the book was prepared as a part of a collaborative project in higher education, the EU Asia Inter University Network for Teaching and Research in Public Procurement Regulation 2009-2011, funded by the EU. This project involved several universities in Europe and Asia and has sought to promote and support the teaching of public procurement in Europe, Asia and globally. This text is one of five books produced under the auspices of the project that are designed to be used as resources in the teaching of public procurement law and regulation. The main editors and chapter authors are listed below, but it should be recognised that the text is a collaborative effort of all the partners to the extent that it has benefited from input by, and discussions between, many different persons at the different partner institutions. In addition to the authors and editor mentioned below, the text has benefited from editing and proof reading by Laura Graham at the University of Nottingham and text assistance from Marie Pade Andersen , Cecilie Voss and Kim Jørgensen at Copenhagen Business School whose assistance the project would like to acknowledge gratefully. The contents of the book are up to date as of August 2010. It has also been possible to include later developments in some parts of the book.

Abstract: There is a great deal of confusion about the meaning of the concept public-private partnership (PPP). Much is written on the subject but only rarely do authors give an adequate account of what they mean when they talk about PPP, nor do they acknowledge that there exist qualitatively different PPP research traditions. The lack of conceptual clarity leads to false statements about PPP, since what is true for one specific PPP-type does not necessarily apply to other forms of PPP. This paper reviews the literature on PPP and argues that there exist at least five distinct approaches in the burgeoning PPP literature with different origins and that it is vital for analytical clarity that authors place themselves within one of these traditions when doing research on PPP.

With Comparative and Multi-level Case Studies from Denmark and IrelandHelby Petersen, Ole (Frederiksberg, 2011)[More information][Less information]
Abstract: This PhD dissertation studies national similarities and differences in policy and regulation of public-private partnerships (PPPs), with an empirical focus on Denmark and Ireland. The starting point and motivation for the study is the observation that whereas PPPs are often depicted in the academic literature and in policy practice as a globally disseminated governance scheme, in reality, a closer examination of the PPP reform landscape reveals significant differences in national governments’ PPP policy and regulation and in the amount of actually implemented PPP projects. By comparing the initiatives taken by the Irish government, which has embraced PPPs, with those of the Danish government, which has been a PPP sceptic, this study inquires into the fundamental questions as to how, why and to what consequences some governments have developed widespread policy and regulation frameworks to support the implementation of PPPs, whereas others have been much more reluctant. The dissertation addressed four research questions: (i) what are the key actors, strategies and institutions that create policies and regulations for the formation of PPPs?; (ii) how did governments’ PPP policies and regulations develop over time, and how can their similarities and differences be explained?; (iii) how do differing national policy and regulation frameworks serve to facilitate or hinder the formation of PPPs, exemplified by four case studies from the schools sector?; (iv) what framework conditions does the EU set for PPP initiatives at national and sub-national levels? The main aim of the dissertation is to study how and why national PPP policy and regulation frameworks developed over time. At the national government level, the study thus contains both diachronic and synchronic analysis. Furthermore, in line with previous research within what has been called the governance approach within PPP studies, policy and regulation are also seen as constitutive elements that tap into and set the general framework conditions and institutional ‘rules of the game’ for the realisation of concrete PPP projects. The comparative interest at the central government level is thus supplemented by an analysis (a) of the interplay between decisions about policy and regulation at the national level and the formation of concrete PPP projects, and (b) of the EU’s role in regulating decisions about PPPs at national level and in relation to the formation of concrete PPP schemes. A main finding is that whereas academic PPP literature often portrays governments’ rationales for resorting to PPPs in terms of achieving innovation, collaborative advantage, value-for-money, new market possibilities, improved risk sharing etc., the findings brought to the fore in this dissertation suggest that a primary objective indeed was to remove major public infrastructure investments from governments’ balance sheets, and thereby reduce the pressure on public capital budgets and provide more infrastructure than would otherwise be possible. However, as the off balance sheet rationale has been shown to be largely false, because there is always a bill to pay in the long term, this raise a number of broader legitimacy and accountability issues, which the present PPP policy and regulation frameworks of governments do not seem to adequately address.

A processual and embedded explorationStelling, Christiane (Frederiksberg, 2014)[More information][Less information]
Abstract: This thesis addresses the need, development and management of trust in Public-Private Partnerships (PPPs), an issue that thus far has received only very little attention. For this purpose, the dissertation contributes with four separate articles, of which the first two explore the main concepts – PPPs and trust – while the last two present the empirical exploration of trusting in PPPs by drawing on four in-depth case studies. The exploration of the PPP concept in the first article focuses on the definitory and classificatory practices across disciplinary and professional fields and contributes with an inductive map of the dominant patterns. The review of PPP publications argues that the main divergence lies in the focus on two differing dimensions. While a first group focuses on PPPs as a new way of distributing responsibilities across public and private partners a second group defines PPPs as a new means for joint decision-making and interactive collaboration between public and private partners. For the thesis it is especially the second dimension – the relational - that becomes relevant when trust moves centre-stage. In the second article, the dissertation addresses trust conceptualizations in an interorganizational setting. The article argues for a more processual approach to (re)embed trust in time and space. Following, the paper develops a processual framework for studying interorganizational trusting as ever evolving, always embedded and not least rooted in individual experiences of organizational members from various organizational levels. Finally, the article highlights the constitutive importance of contingency not only creating the need for trust but also its precondition. It is because we experience the future as open (contingent) that we are in need and able to form trust, i.e. suspend doubts and form positive expectations about another’s future behaviour despite he/she has the possibility for alternative actions.

An explorative study of the contracts of the Tender Electronic Daily (TED)la Cour, Lisbeth; Milhøj, Anders (Frederiksberg, 2013)[More information][Less information]
Abstract: Public procurement is estimated to constitute more than 16% of GDP in the EU, see e.g. Ramsey (2006). This is one of the reasons why a lot of interest has been attached to this topic. Most of the papers in this field have been of a theoretical nature but during the last ten years also a few empirical studies have become available, see e.g. Marion, J. (2007) and Bajari et al (2008). At the EU level liberalizations have been going on since the late 80’ies (see e.g. the EU commission (1985). Here certain regulations imply that public projects of a certain size need to be subject to a public tender. Again according to Ramsey (2006) around 16% of all public procurement in the EU is subject to these rules and regulations and information on the contracts corresponding to these 16% can be found in Tenders Electronic Daily (TED) database. In general, the hypothesis is that public procurement will increase competition and ultimately lead to cheaper contracts for the authorities, see e.g. Cecchini (1988) for the economic arguments. But in practice: do the rules and regulations ensure more competition? Do they lead to more internationalization in the sense that more foreign firms become contract winners? Do the government and municipalities in the EU countries actually gain economically from the procurement? Does the choice of type of procedure matter? A lot of interesting questions immediately pops up and some of them – but only some of them - may be analyzed based on the content of this data base. Still, due to the large coverage and the international nature of the data base we believe that a thoroughly study of the possibilities of TED is of major interest and the present study is just a first step in this direction. One of the students who extracted the TED data has also used them for analysis in his master thesis, see Bundsgaard (2010). He has, however, limited his interest to analyze the choice of procedure: auction vs. negotiation and therefore our study has a broader scope when it comes to available variables. To our knowledge we are the first group of researchers who begins to analyze the content of this database using explorative statistical techniques based on a broad range of variables.

Abstract: I dette working paper præsenteres og diskuteres et e-læringskoncept: Pædagogisk Selvtræning. Først vises den medietekniske udformning. Dernæst præsenteres et læringsteoretisk grundlag for konceptet ud fra K. Illeris, 2001. Det starter ud fra de læringsprocesser (kognitive, psykodynamiske og sociale), som foregår i brugere af konceptet, lærere så vel som studerende. Ud fra denne model diskuteres, hvordan denne viden kan være vejledende for lærerens resp. den studerendes direkte aktivitet i klasselokalet. Problemet for brugeren (en lærer eller en student) er dels at diagnosticere situationen på holdet, ved eksamen e.l. og dels at finde/vælge en reaktionsmåde, der er relevant hertil. Det er disse kompetencer, Pædagogisk Selvtræning søger at udvikle. Til sidst diskuteres, hvordan Pædagogisk Selvtræning kan videreudvikles og indplaceres ift. andre, fx IT-baserede undervisningsformer. URI: http://hdl.handle.net/10398/6691 Files in this item: 1

Abstract: A central issue in science policy today is the changing role and function of research evaluation. How is quality selected, has local organizational traditions and managerial practices influence on the research evaluation? Who is perceived as peers or evaluators by the researchers and by managers? Recent organizational theory has focused on organizational and social dimensions in private knowledge-based companies, but left out research organizations. How important is the organizational context for the research evaluation processes? The paper will present results from an interview-based study of four private and public research organizations and discuss the importance of the organizational context on the production of new knowledge.

the Danish stock market since World War 1Risager, Ole (København, 1998)[More information][Less information]
Abstract: Abstract: This paper contributes to the growing literature on mean reversion in stock markets by examining a newly constructed Danish data set for the period 1922-95. Variance ratio tests clearly reject the random walk hypothesis at the 2-year horizon, that is, the riskiness of a 2- year investment is significantly less than twice the risk of a 1-year investment. Variance ratio tests for 3- and 4-year horizons are not significant under conventional significance levels, whereas autocorrelation tests of the joint hypothesis that there is departure from random walk at all horizons tend to reject the random walk hypothesis and support the mean reversion hypothesis.
