TriECON Workshop on Trade Unions and Migration

The increase in the number of international migrants in high-income countries over the past decades has led to concern about how trade unions approach migrant workers. Hence, the IAAEU, in cooperation with the Chair of Personnel Economics at Trier University, organised a one-day online workshop on the topic of Trade Unions and Migration on December 17, 2021. Eight scientific projects were presented, and around 20 researchers and guests participated in the workshop. The workshop offered a virtual platform to maintain lively scientific exchange and networking among junior and senior economists and other social scientists even during the corona pandemic.
The workshop included qualitative and quantitative studies that examine the trade union strategies regarding immigrant workers in different European countries. The immigration policy and international migration flow were also investigated. Fenet Bedaso, a research associate at the IAAEU and the Chair of Personnel Economics at Trier University, presented a joint research project with Uwe Jirjahn and Laszlo Goerke on the topic of "Does Integration into Society and Workplace Play a Moderating Role?". She discussed that immigrants are less likely to join trade unions than local workers in her presentation. She also emphasised that social integration into society and workplace integration through the works council positively influence the trade union membership of immigrants in Germany.
In addition, several aspects, such as trade union wage effects, labour protection, and ethnic identity, were examined in relation to immigrants in the labour market. After each presentation, participants actively engaged in questions and comments, which enhanced exchanging ideas and networking during the workshop.
We thank the speakers and participants for interesting presentations, lively discussions, and constructive comments that made the workshop successful.

Presentation on "Gender aspects in the Platform work"

We would like to invite you to the presentation on "Gender aspects in platform work“, held by Dr. Isabell Hensel. The presentation will be taking place on Wednesday the 8th of December, from 6:15 pm until around 08:00 pm. Due to the recent developments in the Corona pandemic it will exclusively take place via Zoom.
Platform work has influenced the world of work in a variety of ways, and has most recently taken form in Germany’s federal labour court with the so called "Crowd-worker-decree". In the area of legal sciences, discussions on this topic mainly focus on the legal status of Crowd-, Gig- or Cloud-workers. In contrast, research on gender specific effects of platform work is still rare, although especially U.S. American literature has acknowledged many issues involving gender, like salary differences between men and women, admission requirements, contract binding pressure, sexual harassment, physical assault as well as discriminating algorithms.
Dr. Isabell Hensel is an academic employee at the European University Viadrina in Frankfurt (Oder), where she does research in the field of labour law 4.0, platform economy, sociology of law and gender studies. In light of her work at the expert commission of the federal German parliament, she has studied the relevance of gender equality in platform work. She will share some results of her work in her presentation.
To better plan the event we would like to ask you to register via email (This email address is being protected from spambots. You need JavaScript enabled to view it.) beforehand. You can find the brochure for the event here.

TriECON Workshop on Gender Inequality in Labour Markets

Although the traditional idea of the distribution of labour between the sexes is losing its significance in today's society, systematic disparities between men and women still persist on the job market, making themselves noticeable through income inequality and limited career options for women for example. Examining these disparities was the top priority of the tenth online workshop of the TriECON Series, with 48 international researchers attending. Nine researchers from eight different countries presented their research, with the overall aim to facilitate and promote the exchange of research ideas and concepts.
You can find the entire programme here. For more information on the TriECON Workshop Series, please take a look at our website.

Series of articles on "Case Processing in Labour Law“

Dr. Thomas Klein and Dominik Leist set the upcoming series "Case processing in labour law“, appearing in the current edition of "Zeitschrift für das Juristische Studium", in motion with a new contribution titled "Collateral third-party-effects of fundamental constitutional rights and industrial action rights in light of strike mobilisation at work". This series is primarily directed towards students with a focal point on labour law, and accompanies the IAAEU’s podcast on labour law by examining the cases brought up markedly. The series raises awareness and trains structural thinking, making the application of abstract knowledge on a tangible case easier. This article specifically illustrates how to approach cases and find solutions, which scarcely comes up in decision rulings or in practice cases. Subsequently, the series "Case Processing in Labour Law“ can be seen as a self-initiated method to successfully prepare for examinations in the field of labour law.

Sixth TriECON Workshop on Inequality and Polarisation

The OECD’s annual Employment Outlook 2017 sheds light on the growing polarisation of wage and income distribution - employment rates in lower and higher qualified sectors of work are increasing, whereas the proportion of jobs in mid-qualified sectors is decreasing. In answer to this, the sixth workshop of the TriECON Series brought forward topics like inequality and polarisation. In total, more than 20 researchers took part in the workshop. Therefore, the TriECON online conference represents an important virtual opportunity to maintain scientific exchange, even during the pandemic.
The presentations during this workshop were primarily dedicated to the causes and consequences of this growing inequality and job polarisation. One presented study analysed the effect of migration on the polarising pattern in the employment structure. Another study investigated whether changes in labor market institutions (trade unions, minimum wage etc.) have an effect on the structure of employment. In addition, one project focussed on the discrepancy between acquired and requested qualifications in a time of recession. On top of that, other issues like wage negotiations of employees, digitalisation and offshoring were discussed in the context of job polarisation. The presentations and their results once again underlined the need for adequate policies to counteract the polarisation of wage and income distribution. You can find the complete program of the workshop here.
We would like to thank all participants for their interesting presentations and numerous comments and suggestions, making the workshop very successful!

TriECON Workshop on COVID-19 and Labour Markets

The spread of the COVID-19 Pandemic has had a considerable impact on the labour market and economy of many European countries since March 2020. Many employees now work from home due to restrictions imposed by the government. Some sectors were forced to decommission their ongoing course of business permanently. Subsequently, many researchers are investigating the effects that the COVID-19 Pandemic may have on the labour market. In order to facilitate a deeper look into this issue, the IAAEU, along with the Chair of Personnel Economics, has hosted a one-day workshop on the topic of "COVID-19 and Labour Markets", held on May 7th, 2021. More than 30 scientists and other interested extern guests took part.
During the workshop, eight scientific papers were presented and discussed. Presentations ad-dressed topics such as "home office, work performance and well-being of employees", "autono-my during the COVID-19 Pandemic", and "re-opening of schools and the spread of the Pandem-ic". Dr. Yue Huang, a researcher at the IAAEU and the Chair of Personnel Economics of the Trier University, presented her research on "Home Sweet Home: Working from Home and Employee Performance during the COVID-19 Pandemic in the UK". She demonstrated that employee per-formance in the UK, measured by self-reported productivity and working hours, is positively cor-related with the frequency of working from home. Many employees are in favour of home office even after the Pandemic. These results are politically relevant and highlight the need to create a suitable regulatory setting for the future establishment of the home office. Each presentation was followed by a lively discussion between presenters and the audience, which provided all par-ticipants with networking opportunities despite the online format. The successful online event also reflects the topic of home office at the workshop.
We would like to thank all presenters and participants for their excellent presentations and con-tributions to the discussion. You can find the program of the workshop here, as well as more in-formation on the TriECON Workshop Series in the Summer Semester of 2021 on our homepage.

Interdisciplinary Workshop at the IAAEU

On the 20th of April 2021, the interdisciplinary online workshop "Digitalisation in Employment Relations", organised by the IAAEU, took place. Guest speakers from the field of law were Prof. Dr. Daniel Ulber and Ass. Jur. Adrian Bromme, along with Prof Dr. Sabine Pfeiffer and Dr. Ulrich Zierahn as guest speakers from the economics workgroup. A large group of attendees, namely the directors of the institute, as well as the research assistants of both workgroups and other attendees, partly from the University of Trier participated in the workshop.
Dr. Ulrich Zierahn commenced with a presentation evaluating the "Effects of Digitalisation on the Working World" from an economic perspective. This was followed up by Ass. Jur. Adrian Bromme, who talked about the legal conditions of further training of employees in response to changes in activity profiles as a result of digitalisation, titled "Digitalisation as a Challenge for Personnel Trainings".
In the second part of the workshop, Prof. Dr. Sabine Pfeiffer assessed from a sociological perspective the progression of digitalisation in the past decades, in a presentation titled "A decade 4,0 Discourse - a Mid-Term Evaluation of the Digital Shift in Work Life". The workshop was concluded by Prof. Dr. Daniel Ulber, who lectured about the topic of "Challenges of Digitalisation for Working Hour Laws“, specifically focussing on the subject of removing of boundaries between work and leisure due to technical possibilities through digitalisation. Each presentation was followed up by animated discussions between lecturers and attendees. Both the presentations and the concluding discussions lead to interesting insights into the contrasting areas of research.
The organisers would like to thank all lecturers and attendees for their contribution and involvement

Successful 13th Workshop on Labour Economics (WLE) at the IAAEU

On March 25-26, the IAAEU hosted the 13th edition of the Workshop on Labour Economics (WLE). Though no one at IAAEU had any experience with hosting such large online conferences, "Everything went surprisingly well" as Jonas Feld put it, head of organization. Usually, the WLE takes place on the premises of the IAAEU, on Trier University's Campus II. But this year, for the first time, it was converted into a virtual format.
The opportunity to attend a conference even with current travel restrictions explains why there were such a large number of attendees compared to previous versions of the annually held WLE. More than 130 people had registered for the event, as many as never before. Together they listened to 57 presentations listed on the program this year, also a record high.
Another reason behind the gradually growing interest in the WLE is surely the broad spectrum of topics touched on, and the increasing scientific reputation of this conference. Several presentations depicted Germany's job market situation, specifically focusing on the general development of wages, as well as the differences in wages between the public and private sector and the influence of the Hartz-reforms. Other presentations featured topics such as temporary employment, education, or job satisfaction – many also from a cross-country comparing perspective. Meeting the interests of many participants, presentations and subsequent discussions also acknowledged subjects such as the influence of digitalization or gender pay gaps between women and men.
Similar to previous years, the main emphasis was put on the research interests of the employees at the IAAEU and the employees of the chair of personnel economics at Trier University: There were many lectures on the current standing and the influence of trade unions and also on the labor market integration of immigrants. To conclude the conference's first day, Professor Guido Friebel from Goethe-University Frankfurt gave a keynote lecture on personnel economics experiments, highlighting associated methodological challenges.
The 2021 WLE Best Paper Award was conferred to Yajna Govind, a doctoral student at Paris School of Economics, for her job market paper entitled "Is naturalization a passport for better labor market integration? Evidence from a quasi-experimental setting ".
As summed up by Jonas Feld, representing the IAAEU, "the interest in our workshop is increasing year by year. We are delighted to have met these growing needs by hosting a virtual conference even in these particularly unusual times." Nevertheless, the WLE-Team hopes to welcome all attendees in person at the premises of IAAEU at Campus II from next year on again.

Flight delay compensation despite a strike - Aspects of labour law and fundamental rights of a consumer law issue

According to the European Flight Compensation Regulation, passengers are entitled to compensation in the event of cancellations and delays. However, the claim does not apply if the air carrier can prove that the cancellation is caused by "extraordinary circumstances" which could not have been avoided even if all reasonable measures had been taken. The question of whether these "extraordinary circumstances" also include strikes by airline staff, which is extremely relevant in practice, is judged differently by the German courts. In any case, the European Court of Justice (ECJ) did not classify a wildcat strike by employees of an airline (TUIfly) as an "extraordinary circumstance". Dr. Thomas Klein has examined the issue in detail in a recent article entitled "Compensation claims under the Flight Compensation Regulation in the event of strike-related cancellation or delay". In the first part of the study, he develops typical case groups taking into account the law on industrial disputes and points out that, the air carriers' staff strikes, contrary to the former case law of the Federal Court of Justice (Bundesgerichtshof), do not generally lead to the loss of compensation. In the second part of the study, he examines the fundamental rights dimension of the problem, which has not yet been adequately captured and appreciated by the case law, and comes to the conclusion that fundamental rights considerations also do not force the elimination of compensation. The article was published in issue 1/2021 of the European Journal of Business Law (EuZW 2021, 23-29).

TriECON Workshop on Media Economics

Media has the potential to influence the behaviour of people and of companies in a large variety of ways. Especially in the digital age, where new technology is close at hand and media is omnipresent, on mobile phones for example. Consequent implications were the main focus of the fourth online workshop of the TriECON series this winter semester. The aim of the event was not only to acquaint scientists with one another, but also to further motivate the exchange of research ideas between them. Thirty participants from all over the world took part in the TriECON Workshop.
Nine scientific papers on the subject of "Media Economics" were presented and discussed during the course of the workshop. In part, some studies explored the influence of media on voting behavior using German and Russian data. The workshop also set out to question the link between the language in which mass media covers political topics and between the political preferences of readers. Another study analyzed the effects of crime related media coverage on the attitude of civilians towards immigration. Click here for a full programme of the Media Economics Workshop.
