Institute for Economic and Legal Research Frankfurt (IWRF)
Profile of the institute
We are a research institution of Faculty 3: Business and Law and perform applied research and development in close cooperation with partners from business, politics, and administration. This gives us an optimal connection to the practical world. The focus of our research activities lies on projects that are of special significance in Frankfurt am Main and the Rhine-Main region. Our research projects strive to put results-oriented changes into practice and to transfer knowledge to the interested public. The integration of our students also allows us to ensure high-quality training.
Our declared goal is to support our members in their research projects and offer them an interdisciplinary and transdisciplinary platform. We will also gladly help our members by
- giving them advice when they apply for third-party funding,
- supporting them in developing networks and cooperation negotiations,
- and disclosing their research results to the media, at regular events, and publishing them in our newsletter.
Our cooperation partners from the professional world – be it business, politics, or administration – will gladly help you with advice for specific topics in economics or law research. We are always grateful for any new suggestions that come from outside the organization, and we attempt to network the right researchers with the professional world.
Opportunities for guest researchers

Taking knowledge transfer seriously
In regular – but very different – events, we ensure a knowledge transfer for our research projects, as can be seen in these examples: The brown-bag seminar is a relaxed meeting that combines the “good” with the “useful”! It is “good” because topical news from research projects (work-in-progress) or research results are presented and discussed every month during the lecture periods. It is “useful” because the brown-bag seminar simultaneously represents a well-earned lunch break for the participants, where they can eat the lunch they brought in little brown bags. Brown-bag seminars are very popular and attract many visitors. In our regular research symposium, “Academia and professional practice exchanging ideas on current challenges," we present current research topics from the disciplines of law and economics. It serves to facilitate the transfer of knowledge and offers attendees opportunities to exchange information and develop cooperation. Detailed information on dates, lectures, and lecturers can be seen in advance on our website. If you are interested in participating in an academic event or holding your own event, we will gladly provide you with assistance.
The exchange of information between research and practice is decisive for profitable and sustained success. The Institute for Business and Law (IWRF) at the Frankfurt University of Applied Sciences presents the current research activities of its members from the disciplines of law and economic sciences in these conference volumes. The articles are based on lectures held during the symposia on "Academia and professional practice exchanging ideas on current challenges.” The lectures reflect the special significance of the Rhine-Main region as an important economic and financial center, transportation and logistics hub, and as a region of cultural and scientific significance. The selection of projects provides a good impression of the broad range, the high quality, the interdisciplinary approach, and the application-oriented philosophy of research at the faculty for Business and Law.
B2C e-commerce is still one of the fastest growing marketing channels in almost all product categories yielding to less bundled direct-to-consumer deliveries. Last mile deliveries cause costs and emissions especially in urban areas with a high density of e-customers. Therefore, stakeholders in the context of last mile parcel deliveries are interested in implementing efficient, innovative and ecological last mile concepts. In our customer-driven central last mile micro depot (CMD) project a potential analysis was carried out for the implementation of a CMD with the aim of environmentally-friendly and bundled last mile delivery. Our paper tries to close a research gap by examining acceptance and willingness-to-pay for an alternative last mile delivery concept from the perspective of the customer. Our empirical results based on a survey among German major city residents indicate that city residential areas are potentially more suitable for the realization of a CMD-project than other areas. Furthermore, younger and employed inhabitants are most willing to use the CMD. Based on our statistical model we are able to predict values for the willingness to pay per parcel for a specific population of urban inhabitants.
Leadership is changing due to many digital influences. Digitization requires new leadership skills and will increasingly produce automated decisions. Such “management by systems” and more independence of the employees leads to agile forms of organizations. Both managers and employees will use artificial intelligence and bots to interact with one another. The article shows that agility requires more leadership and “cyber leadership” requires more artificial intelligence.
The current study explores the working conditions of lesbian women in Germany. It compares lesbian women's experiences to those of heterosexual women and examines the level of discrimination during job-application for women who enter professional life. The results of an experimental setting indicate that lesbian women do face discrimination when applying for jobs, as they are less often invited for job interviews. Another important result, based on survey among lesbian and heterosexual women shows that lesbian women experience stronger discrimination on the job due to their gender than their sexual orientation.
Between 2006 and 2009, the authors studied the role of gender-specific negotiation skills of women for their advancement and obtained salary (Ruppert/Voigt 2009). In 2017, a follow-up study with the same methodological design examined to what extent the results found at that time are still applicable. We see that ten years after the implementation of the original study things are (mostly) as they were: men generally have a much more positive attitude towards negotiation and women are more frequently nervous and fearful in salary negotiations. Neither gender invests a lot of time in preparing for negotiations. And in the end we can note again: men achieve significantly better results.
Today we live in a post-truth and highly digitalized era characterized by the flow of (mis-)information around the world. Identifying the impact of this information on stock markets and, moreover, forecasting stock returns and volatilities has become a much more difficult, and perhaps an almost impossible, task purpose. This paper investigates the impact of macroeconomic factors on the German main stock index, the DAX30, for the time period from 1991 to 2016. There are no comparable investigations for the DAX regarding this time period and the GARCH approach in the literature. Using a dataset about 23 variables and over a timeframe of about 25 years, we find evidence that the growth rates of money supply M1 have a strong impact on the stock returns. The results illustrate that in the post-crisis period more macroeconomic factors have a significant impact on the German stock market compared to the pre-crisis period. This implies that in the post-crisis period a macro-driven market is prevailing. In the post-crisis period, however, increasing saving rates, M2 and M3 lead to shrinking stocks values due to higher risk aversion.
Economic theory implies that research and development (R&D) efforts increase firm productivity and ultimately profits. In particular, R&D expenses lead to the development of intellectual property (IP) and IP commands a return that increases overall profits of the firm. This hypothesis is investigated for the North American automotive supplier industry by analyzing a panel of 5000 firms for the years 1950 to 2011. Results indicate that R&D expenses in fact increase profitability at the firm level. In particular, increases in the R&D expense to sales ratio lead to increases in the profit contribution of intangible assets relative to sales. This indicates that more R&D intensive IP should command higher royalty rates per sales when licensed to third parties and within multinational enterprises alike.

What assessment and expectations do students have?
In 2015, the authors already presented the results of a study on the influence of the selected negotiation strategy and the gender of the negotiating person, and they examined the interaction that these two variables have on the negotiation success of executives in salary negotiations (see Ruppert/Voigt 2015b). This study showed that executives rate negotiation tactics that are part of a fact-oriented, cooperative negotiation strategy as better in terms of the chances of success in salary negotiations than negotiation tactics that are used in the context of an assertion-oriented, hard negotiation strategy. In the survey experiment they performed in this study, the fact-oriented, cooperative negotiation strategy proved to be more successful (even if only minimally) than the assertion-oriented, hard strategy (see Ruppert/Voigt 2015b). In parallel to this research project with executives, they also performed a study with students using the same methodological tools and compared the results of the two studies. We see that the assessments and expectations of the students clearly differed from those of the executives. These differences have implications for teaching at universities, in particular in terms of teaching key skills that need to be discussed further.

for Recipients of Disability Insurance Benefits in Switzerland
This paper evaluates a placement coaching program implemented in Zurich during 2009–2013 that focused on the reemployment of persons drawing disability insurance (DI) benefits. A private company was commissioned to implement the program. Kernel-based matching and radius matching with bias adjustment estimators combined with difference-in-differences are applied to administrative panel data. The estimates point to a successful project in terms of a reduction in DI benefits and an increase in income even in the medium-run. A simple cost–benefit analysis suggests that the project was a profitable investment for the social security system. Sensitivity analyses indicate that the results are robust to confounders and further specification issues. An interesting policy implication is that it seems possible to enhance the employment prospects of disabled persons with a relatively inexpensive intervention which does not include any explicit investments in human capital.

Women in management positions in Germany are still underrepresented. it appears that the measures used for changing the situation have not been sufficient to date. Numerous studies already deal with the barriers that women encounter and how to diminish / prevent them. However, it is apparent that the previous tools and measures are not sufficient to help more women accede to management positions and be accepted. This study looks at the observed behaviors that are a sign of acceptance of executives. We assume that acceptance can have a significant impact on a career. Initial results indicate that, in the perception of the respondents, particularly acceptance from executives and colleagues has an impact on professional success. Furthermore, different indicators can be identified depending on the gender of the executive.

Sustainability has been defined by the Brundtland Commission (Brundtland, 1987) as “meeting the needs of the present without compromising the ability of future generations to meet their own needs”.
In times of increasing expectations of customers, shareholders, employees, and communities as well as the general public about corporations’ contributions to sustainability (WBCSD - World Business Council for Sustainable Development), the latter are severely and continuously criticized for actions that contradict their glossy sustainability reports (Holliday, 2010). However, it is often the case that such criticism is rooted in a lack of awareness of the complexity of relationships and the role that sustainability plays within the context of a firm’s operations, particularly SMEs, which cannot dedicate major resources to cope with the issues. Therefore, the question arises of what universities can do to build awareness and understanding among students in order to prepare them to cope with sustainability aspects in their future careers (Starik et al., 2010). This paper presents findings based on quantitative and qualitative data from five consecutive cross functional courses in sustainability for students in business, law, architecture, health management and engineering, and evaluates the extent to which their attitude and awareness changed over the course. Recommendations are given for institutions in higher education as well as for companies to follow up with further training initiatives for junior managers.

The topic of gender-specific differences in terms of career opportunities is controversial. Different studies show that compared to other European countries, the potential of women in Germany, in particular well-educated women, has not been fully exhausted. This study intends to show to what extent the company culture, i.e. values, standards, attitudes, convictions, behaviors, and processes prevalent in the companies, has a beneficial or detrimental effect on the career perspectives of women.

The Institute for Economic and Legal Research Frankfurt regularly carries out academic events. These include a monthly brown-bag seminar taking place during the lecture period, with the goal of presenting research projects / topics and discussing them with the participants at the end. This is to help the researchers at our faculty get to know each other better and promote research networks and it also enables researchers to present their research theses or results.
Brown-bag seminars are events that take place in a relaxed setting during lunch. The term "brown bag" refers to the lunch bags the participants will often bring along with them to the event. In these seminars, research projects (work-in-progress) / research topics are introduced and discussed. These events are intended to help the researchers at our faculty get to know each other better and promote research networks, they also enable researchers to present their research theses or results.
The brown-bag seminars take place once a month on Tuesdays during the lecture period from 11:45 - 12:15.

Another occasion for combining practice and theory are academic interdisciplinary conferences. The subject of the conferences are academic and application-related lectures held by academics and business representatives on current topics and issues. The conferences are directed at partners and representatives from business, science, and politics.
Academic interdisciplinary conferences provide another opportunity to connect practice and theory. The single and multi-day conferences have the advantage that current topics and questions can be explained and discussed in detail. The application-related lectures are supplemented by an extensive supporting program. The conferences are directed at partners and representatives from business, science, and politics.
1st conference (German only) on logistics "Air cargo supply chain" on & September 15-16, 2016
Furthermore, we organize scientific symposia that present the expertise and research activities of the faculty. During these symposia, current research topics of the faculty are presented from law and economics.
Our regular symposia create a bridge to the practical world. We present and discuss current research topics from the disciplines of law and economics. The symposium serves the transfer of knowledge between science and application and provides an opportunity to communicate and develop cooperation. The subject-related profile of the faculty and institute is reflected in the different introductory lectures. The lectures reflect the special significance of the Rhine-Main region as an important economic and financial center, transportation and logistics hub, and as a region of cultural and scientific significance.
