Investment banks and underpricing

Baltes, Pascal (2018)

After the Internet Bubble in 1999-2000, US investigators found that investment banks have manipulated initial public offerings (IPO) in differing schemes to create higher profits at the cost of investors and issuing firms. One of these schemes included profit sharing agreements in which an investment bank offered underpriced share allocations of rationed IPOs to buy-side investor clients in ret...

Vertical Governance between Airlines and Airports - A Transaction Cost Analysis

Fuhr, Johannes ; Beckers, Thorsten (2006)

Telling the Truth May Not Pay Off: An Empirical Study of Centralized University Admissions in Germany

Braun, Sebastian ; Dwenger, Nadja ; Kübler, Dorothea (2010)

Matching university places to students is not as clear cut or as straightforward as it ought to be. By investigating the matching algorithm used by the German central clearinghouse for university admissions in medicine and related subjects, we show that a procedure designed to give an advantage to students with excellent school grades actually harms them. The reason is that the three-step proce...

Quality and resource efficiency in hospital service provision: A geoadditive stochastic frontier analysis of stroke quality of care in Germany

Pross, Christoph ; Strumann, Christoph ; Geissler, Alexander ; Herwartz, Helmut ; Klein, Nadja (2018-09-06)

We specify a Bayesian, geoadditive Stochastic Frontier Analysis (SFA) model to assess hospital performance along the dimensions of resources and quality of stroke care in German hospitals. With 1,100 annual observations and data from 2006 to 2013 and risk-adjusted patient volume as output, we introduce a production function that captures quality, resource inputs, hospital inefficiency determina...

The economics of financing and integrating renewable energies

May, Nils Günter (2018)

This dissertation comprises three chapters on the economics of financing and integrating renewable energies and on designing associated support policies. The transition toward carbon-neutral economies requires large-scale investments into renewable energy. The integration of these intermittent renewable energies poses new challenges to power systems designed around dispatchable thermal power pl...

Experiments in competition, cooperation, and learning

Kapitel 1 und 2 behandeln Lernverhalten in einem opaken Cournotmarkt, in dem Teilnehmer in fixen Gruppen über hunderte Perioden interagieren. Kapitel 3 dreht sich um die Frage, wie Teilnehmer lernen ein komplexes Spiel um Einfluss zu spielen....

Experiments in risk, insurance and development

Serwaah-Panin, Amma (2018)

The three papers of this dissertation use experimental methods to explore how individuals make decisions in the presence of risk. The papers contribute both theory and empirical evidence to questions about intertemporal decision making in the presence of risk as well as insurance choices in a developing country. Chapters one and two focus on advancing theory and evidence about fundemental decis...

Why and how did Israel adopt activity-based hospital payment? The Procedure-Related Group incremental reform

Brammli-Greenberg, Shuli ; Waitzberg, Ruth ; Perman, Vadim ; Gamzu, Ronni (2016-09-01)

Historically, Israel paid its non-profit hospitals on a perdiem (PD) basis. Recently, like other OECD countries, Israel has moved to activity-based payments. While most countries have adopted a diagnostic related group (DRG) payment system, Israel has chosen a Procedure-Related Group (PRG) system. This differs from the DRG system because it classifies patients by procedure rather than diagnosis...

Application of multiday 24h-accelerometry in epidemiology to study habitual overall physical activity, activity intensity levels, and their determinants

Jaeschke, Lina (2018)

Physical activity (PA) is an established protective lifestyle factor for chronic disease risk. Reliably assessing PA, deriving unbiased PA estimates, and knowing determinants of PA are preconditions for drawing persuasive conclusions on exposure-disease associations in epidemiology and for successfully implementing PA promotion strate-gies. Most of the evidence regarding PA relies on subjective...

However, breastfeeding rates are sub-optimal at a worldwide scale and could be improved. Rec...

Verwendung von Krankenhausabrechnungsdaten für die Versorgungsforschung in Deutschland

Nimptsch, Ulrike (2018)

Seitdem die akutstationären Krankenhausleistungen in Deutschland auf der Grundlage des fallpauschalierenden Vergütungssystems der Diagnosis Related Groups (DRG) vergütet werden, sind in den administrativen Datenbeständen der deutschen Krankenhäuser umfassende medizinische Informationen verfügbar.

Research Information Standards Adoption

Riechert, Mathias ; Roberson, Owen ; Wastl, Jürgen (2017-03-21)

While Research Information continues to mature as an area of expertise, discussions regarding the implementation and adoption of standardisation initiatives, such as CASRAI and CERIF, have intensified. Possessing the capacity to use a standard does not obligate its adoption, so the extent to which standards are employed varies across use cases and institutions, in a way that is difficult to qua...

Using co-authorship networks to map and analyse global Neglected Tropical Disease research with an affiliation to Germany

Bender, Max Ernst ; Edwards, Suzanne ; Philipsborn, Peter von ; Steinbeis, Fridolin ; Keil, Thomas ; Tinnemann, Peter (2015)

Neglected tropical disease research has changed considerably in recent decades, and the German government is committed to addressing its past neglect of NTD research. Our aim was to use an innovative social network analysis of bibliometric data to map neglected tropical disease research networks that are inside of and affiliated with Germany, thereby enabling data-driven health policy decision-...
