Transparent Research

The first ideas for a Collaborative Research Center on the topic of transparency within taxation and accounting emerged during a bilateral meeting between Caren Sureth-Sloane and Joachim Gassen early 2017. From there on things moved fast; a group consisting of engaged researchers was quickly formed, initial meetings were being held, and preliminary proposals were written. In this first post the initiators and spokespersons of the TRR 266, Caren Sureth-Sloane and Joachim Gassen, look back at how the project came to life, and explain why transparency is not only the subject of their research but also central to their work philosophy by means of FAIR data and open communication. In subsequent blog posts the members of the TRR 266 will share their research and write about their questions and findings in relation to current topics, developments and events.


How did the topic of transparency in accounting and taxation emerge during that brainstorm early 2016?

We met to discuss possibilities for future collaborations, and when discussing themes and possibilities it soon became clear that with “accounting for transparency” we were on to something that offered us to do fundamental research as well as develop an impact on society and the economy. These were two criteria that were very important to us. The latest financial crises and public outrage about multinationals not paying their fair share of taxes have fueled public demand for transparency. For example, prominent accounting fraud scandals and excessive shifting of taxable profits by global corporations have led to concerted regulatory actions with the aim of increasing firm transparency. Consequently, both the amount of available information as well as the regulatory burden of firms have increased substantially world-wide. However, whether this increased level of both information and regulation actually has generated more transparency and its expected positive societal outcomes, is unclear.

We discussed how economic research on regulation has made significant progress in the last decades by focusing on general mechanisms and by testing generalizable models of regulatory effects. However, we thought that moving towards more detailed institutional analysis, focusing on specific regulatory regimes would be promising and allow us to exploit both the technical and institutional expertise in a tentative research team of accounting and tax researchers. The main advantage of this increased focus on detail is that the resulting empirical findings from the field have a higher level of internal validity because the underlying models fit the institutional infrastructure. Even though this strong focus on details means that the findings cannot easily be extended to related problems or situations, the high level of internal validity means that “knowledge that matters” is created.


The focus on accounting, taxation and transparency is clear. But how exactly is transparency defined within the project?

We understand transparency as the quality of information generated, distributed, received, and processed by economic agents. In this regard, quality is a multi-dimensional construct comprising disclosure, accuracy, and clarity of information. Accounting affects transparency whenever it affects the quality of information as distributed to and processed by internal or external stakeholders. Consistent with a sender-receiver framework of information exchange, the sending agent (regulator, managers in firms etc.) can influence the quality of accounting information, for example, by incorporating more details, disclosing it to a broader audience, by auditing it to enhance its accuracy, or by standardizing recurrent information to improve its clarity. Private information gathering and processing activities by other economic agents (e.g., stakeholders, social media) also affect the quality of information.


The two main questions to be answered by the research group are “How does accounting affect transparency?” and “What are the effects of transparency?”. Why is a Collaborative Research Center encompassing 23 projects necessary to answer these two questions?

As we have outlined above, in contrast to traditional research programs in economics that use relatively abstract models, our research program will study a wide set of institutional designs in detail. This means that we will address problems of organizational information flows where decision makers such as managers, investors, and other stakeholders including regulators and tax authorities are involved. This focus on field data, meaning on observations of real life phenomena, enables us to study regulatory effects in the setting where they occur. While investigating human behavior in the laboratory allows for tight controls and thus high levels of internal validity, the regulatory questions that we are interested in cannot easily be transferred to the lab. Managers behave differently from students. Professional investors do not act like retail investors. Taxation systems are too complex for a 15-minute lab briefing. To achieve a balance between internal and external validity we will develop specialized models incorporating the complexity of our regulatory settings and test these models on observational data using field experiments or quasi-experimental settings optimized for causal inference. In order to address our general research questions, we need a wide array of projects covering diverse settings to explore a wide set of institutional designs in detail. Also, we will pool the expertise from managerial and financial accounting as well as taxation to bridge the interdependencies of these fields. In combination, we hope that our 23 projects will help us to better understand how accounting affects transparency and how transparency affects society. Thereby we will contribute to both academic debate and pressing real-life issues such as the development of future tax systems, questions of capital market regulation and the design of incentives schemes or financial reporting regimes.


Joachim, the research program has committed itself to the principles of Open Science. Why and how are the principles of Open Science implemented in TRR 266?

Open science implies conducting research so that everybody can collaborate and contribute. This requires research data, algorithms, and processes to be freely available within data privacy and other legal boundaries. We want our research and data to be FAIR (Findable, assessable, interoperable, and reusable as well as reproducible). We consider this to be crucial since only reliable research can and should generate impact. To be reliable, data and methods need to become transparent for the academic community. In addition, transparent and reusable work can speed up the discovery of knowledge. We are excited that the DFG has coined this part of our project, together with the German Business Panel Project C01 of the Mannheim Group as a potential “paradigm change” for the business research community.

To ensure that the principles of Open Science will be successfully implemented throughout TRR 266 we established the Open Science Data Center (OSDC). within the project structure this is also referred to as Project C02. The OSDC will facilitate reusing, redistributing, reproducing, and replicating research and thus sharing our research outcomes with the scientific community. The activities of the OSDC can be structured into four distinct fields. The OSDC will:

  1. develop and provide tools for a scientific workflow that can be reused and built upon by the academic community at large;
  2. systematically collect data on corporate transparency and make this data available to the academic community;
  3. develop data processing and presentation tools;
  4. offer courses in statistical software design, consulting support for projects, and replication as well as crowd-sourced research events.

What do you believe are the challenges for the Open Science Data Center when implementing the principles of Open Science?

Besides the technical aspects of ramping up such an initiative, we will have to work with the members of the TRR and the wider research community to advocate the benefits of sharing. This also implies that the academic community has to adopt a more constructive error climate. In addition, we will have to work with both administrative suppliers of data (like, e.g. the Bundesanzeiger or tax authorities) and commercial data vendors to make our data inter-operable with theirs. Finally, we need to develop tools and platforms that make it easy for researchers to increase the transparency of their work.


Caren, in addition to sharing the research results with the research community, the project also aims to address target groups other than the research community. How will these groups be addressed and included in TRR 266?

First of all, business administration, as an applied science, needs close interactions with business. This is extremely helpful to identify relevant questions and to verify our methods and findings. In order to develop an impact on society-at-large, we need to build and maintain connections to business, politics, and their stakeholders. We will build on, and extend, a strong network of experts in taxation and accounting in firms and regulatory bodies. Many of our projects rely on detailed internal firm data. Up until now, this data has not yet been systematically collected, and thus no comprehensive dataset is available. Therefore, we will establish a German Business Panel (Project C01) which will become a representative panel of managers bearing responsibilities for accounting and tax matters in German firms. These representatives will be surveyed on a semi-annual basis on topics in the area of financial regulation, the role of information in internal and external decision-making, and on matters of corporate taxation. Furthermore, Project C03, entitled Communicating Transparency, is concerned with communicating our research to the various target groups. We will not only communicate the final results, but will translate it into short texts and visualizations to start a dialogue with both academic and non-academic audiences, allowing us to learn from them and incorporate their questions and concerns into our research. We will host public events and make our data sets available through attractive data visualizations. Finally, in general our research findings will help firms to gauge the consequences of their activities, since we will study the behavior of firms in the face of new regulations and general regulatory uncertainty in the area of accounting and taxation. This can potentially lead to better informed managerial decision-making.


Could you provide an example of a data visualization?

An illustrative example of data visualization is the recently published Tax Complexity Index ( It measures the level of tax (code and framework) complexity faced by multinational companies (MNCs) in 100 countries. We provide our results as an interactive website where users are able to play with and compare countries and complexity drivers, make their own “customized” index, and download the data in order to use our data for e.g. decision support.

More Information

There is no formal definition of Open Science, in fact it is an umbrella term covering various movements fostering sharing and collaborating. The European Commission describes Open Science as representing a new approach to the scientific process based on cooperative work and new ways of diffusing knowledge by using digital technologies and new collaborative tools (European Commission, 2016). The OECD defines Open Science as: “to make the primary outputs of publicly funded research results – publications and the research data – publicly accessible in digital format with no or minimal restriction as a means for accelerating research; these efforts are in the interest of enhancing transparency and collaboration, and fostering innovation” (OECD, 2015:7). As such, Open Science encompasses aspects such as open access, open data, open source software and citizen science. It is important to note that Open Science concerns the entire research cycle; researchers should share and collaborate as early as possible in order to entail a systematic change to the way science and research is done.
