Research Projects

Here you can find information about our current projects as well as a selection of projects we have already completed. The projects range from the dissertations of doctoral students to those with cooperation partners from science and industry.

Political Preferences and International Trade

Policy preferences and resulting regulations influence economic activity - especially political activity across borders. This project studies the impact of policy preferences on trade relations in the European Union. To measure policy preferences and convergence processes we use roll-call votes of the European Parliament. The aim of the project is to identify the influence of different policy preferences on trade flows and emissions included in these trade flows.

Agglomeration and regional disparities in the digital economy

With the rise of the Internet and the rapid growth of the ICT sector, as well as the shift to a more service-based economy, cities seem to be increasingly shaped by their innovation capacities and the presence of a highly skilled workforce. This project examines the impact of the digital economy on the shape and structure of cities and the factors that are conducive to the development of a city's digital economy. The project uses a firm-level dataset based on legal publications of German companies (announcements in the commercial register), as well as novel indicators of local knowledge infrastructure, such as connections and collaborations between universities and research institutions. Thus, this project aims to shed more light on frictions that can amplify spatial disparities not only between regions but also within cities.

Beruflicher Erfolg in der Wissenschaftlichen Forschung

Dieses Forschungsprojekt untersucht das Leben von modernen und historischen Wissenschaftlern, um die Kontexte zu verstehen, die wissenschaftliche Produktion und Innovation fördern. In den letzten 30 Jahren ist die Zahl der Co-Autoren in Wirtschaftszeitschriftenartikeln deutlich gestiegen und die Zahl der "einsamen Sterne" gesunken. Dieses Projekt zielt darauf ab, die Entwicklung der Ökonomie als Disziplin zu verstehen, indem es die Laufbahn und den Erfolg moderner und historischer Ökonomen untersucht, sowie den Einfluss der zunehmenden Spezialisierung und Arbeitsteilung, sinkende Kommunikations- und Reisekosten, sich entwickelnde Anreize durch die Forschungsgemeinschaft, persönliche und thematische Nähe und Heimvorurteile bei der Verbreitung von Artikeln der Wirtschaftsforschung. Dieses Projekt zielt auch darauf ab, den Erfolg von historischen Wissenschaftlern und Erfindern zu verstehen, indem es die wissenschaftliche Produktion über den Lebenszyklus, den Einfluss von wissenschaftlichen Netzwerken und den Einfluss von Standort/Agglomeration bewertet. Darüber hinaus versucht dieses Forschungsprojekt, die Auswirkungen wissenschaftlicher und innovativer Aktivitäten auf die lokale und regionale Entwicklung zu verstehen.

Literary History

For most industries, creative production is highly influenced by the availability, quality, and quantity of colleagues and infrastructure in a given location. However, their role in literary production is less clear. This project aims to identify the circumstances and contexts that foster literary production, including whether location, peer effects, and infrastructure are relevant to an industry in which the most influential producers are often referred to as lone geniuses.

Virtual Proximity and International Trade

International finance literature has shown – both empirically and theoretically – that distance and proxies for informational asymmetries between countries, such as common language, colonial ties, and currency unions, are crucial in explaining bilateral asset holdings and flows. However, over the past two decades, the ICT revolution has changed the meaning of distance. Therefore, this project seeks to understand the impact of the internet on economic activity such as international transactions by studying "virtual proximity" - i.e., the volume of bilateral, inter-domain hyperlinks that connect webpages across countries.

Digitalisation of cultural goods and services

Over the past decade, the consumption and trade of audiovisual services such as music and movies in digital formats has increased significantly. In response, several countries have adopted policies to curb inflows of foreign cultural services, making this one of the sectors with the lowest number of commitments among WTO members. Therefore, this project focuses on the digitization of cultural goods and services, the increase in trade restrictions on these services, the impact of these restrictions on bilateral trade, and how virtual proximity can affect both trade policy and trade in cultural goods and services in digital form.

Visual Artists and Arts Markets

This project focuses on the careers of prominent modern visual artists and the factors influencing their creativity. This research included analyses of the quality of production over the life cycle, the importance of location and colleagues to creative production, the role of an artist's stylistic affiliation, the institutional context in which creativity takes place, the importance of travel as a source of inspiration, the importance of living and working in major art clusters (such as Paris and New York), and how these factors affect the market valuation of the artists' works.

Location & approach

The campus of TU Dort­mund University is located close to interstate junction Dort­mund West, where the Sauerlandlinie A 45 (Frankfurt-Dort­mund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is "Dort­mund-Eichlinghofen" (closer to Campus Süd), and from B 1 / A 40 "Dort­mund-Dorstfeld" (closer to Campus Nord). Signs for the uni­ver­si­ty are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dort­mund.

To get from Campus North to Campus South by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at Campus North and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.

TU Dort­mund University has its own train station ("Dort­mund Uni­ver­si­tät"). From there, suburban trains (S-Bahn) leave for Dort­mund main station ("Dort­mund Hauptbahnhof") and Düsseldorf main station via the "Düsseldorf Airport Train Station" (take S-Bahn number 1, which leaves every 20 or 30 minutes). The uni­ver­si­ty is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.

You can also take the bus or subway train from Dort­mund city to the uni­ver­si­ty: From Dort­mund main station, you can take any train bound for the Station "Stadtgarten", usually lines U41, U45, U 47 and U49. At "Stadtgarten" you switch trains and get on line U42 towards "Hombruch". Look out for the Station "An der Palmweide". From the bus stop just across the road, busses bound for TU Dort­mund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dort­mund main station to the stop "Dort­mund Kampstraße". From there, take U43 or U44 to the stop "Dort­mund Wittener Straße". Switch to bus line 447 and get off at "Dort­mund Uni­ver­si­tät S".

The H-Bahn is one of the hallmarks of TU Dort­mund University. There are two stations on Campus Nord. One ("Dort­mund Uni­ver­si­tät S") is directly located at the suburban train stop, which connects the uni­ver­si­ty directly with the city of Dort­mund and the rest of the Ruhr Area. Also from this station, there are connections to the "Technologiepark" and (via Campus Süd) Eichlinghofen. The other station is located at the dining hall at Campus Nord and offers a direct connection to Campus Süd every five minutes.

The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.

The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent "Technologiepark".
