The effects of both systems are intensively debated by EU Member States as they are striving to implement a European tax system. Its introduction would lead to a switch from SA to FA. Moreover, Pillar One of the recent global tax reform includes a mix of both tax base allocation systems. We find that, against the claims of the EU, FA does not necessarily create lower distortions of the factor allocation. Decisive for that assessment is the level of profit shifting under SA. Our results indicate that, in tendency, the factor allocation is more severely distorted by FA when the profit shifting possibilities were rather low under SA. In contrast to former studies, we highlight the importance of analyzing the status quo under the recently applied system (SA) in order to be able to assess the consequences of a switch from SA to FA. Our results are interesting for policy-makers as they help anticipating reactions of MNEs to a change in the applied tax base allocation system and for companies as a basis for future tax planning.</jats:p>","lang":"eng"}],"status":"public","_id":"41192","department":[{"_id":"590"}],"user_id":"21222","keyword":["Economics and Econometrics","Business and International Management"],"language":[{"iso":"eng"}]},{"year":"2022","citation":{"ieee":"R.

We proxy individuals' risk perception with their willingness to pay for the participation in everyday life and amusements events. We find that participants react to different COVID-19 metrics with varying sensitivity. We observe a saturation of sensitivity for several measures at critical limits used in the political discussion, making our results highly relevant for policy makers in their efforts to direct individuals to adhere to hygienic etiquette and social distancing guidelines."}],"language":[{"iso":"eng"}],"keyword":["COVID-19 reporting","willingness to pay","willingness to accept"]},{"intvolume":"        83","citation":{"chicago":"Ortmann, Regina, Sonja Warkulat, Sebastian Krull, Nina Klocke, and Matthias Pelster. <i>COVID-19 Reporting and Willingness to Pay for Leisure Activities</i>.

Systems under which the formula is identical in all jurisdictions and systems under which jurisdictions can determine the weights on the formula factors individually can be observed. The latter systems produce uncertainty about the overall tax-liable share of the future group tax base. Counter-intuitively, I identify scenarios under which increased uncertainty leads to higher expected future group income. My results provide helpful insights for firms and policy makers debating the specific design of a formulary apportionment system.
