The topic of business acquisitions has been much debated in 2022, largely due to Microsoft’s record-breaking acquisition of Activision Blizzard. Historically, business acquisitions and their corresponding goodwill values have been a thoroughly examined and debated subject between scholars and regulators due to the complexity and ambiguity of goodwill. Discussions regarding goodwill and acquisitions have been the foundation of many studies throughout the years. However, the effects of accounting standards on the factors of business acquisitions have not been examined thoroughly and therefore represents a knowledge gap in existing accounting literature. This thesis examines the relationship between the accounting standards IFRS and Swedish GAAP and their influence on business acquisitions. The focus of the thesis is on the number of business acquisitions as well as goodwill, or value added, to test if the standards themselves affect these factors. Other elements which could affect these factors are presented to broaden the research and isolate the accounting standard variable.  By examining Swedish business acquisitions during a five-year period, the authors have identified 406 business acquisitions that were of such quality that they could be examined further. The study is inspired by other studies in similar areas, especially a paper written by Kashiwazaki et al. (2019) in which the effect of IFRS adoption on business acquisitions in Japan is researched. However, this study is not focused on adoption, the aim of the research is to examine the impact of the standards themselves. By examining the two accounting standards and their correlation with the frequency of acquisitions as well as change in goodwill, patterns can be identified and conclusions regarding whether accounting standards affect the two factors can be drawn. Several theories are discussed in order to contextualize the research, and different perspectives regarding the acquisitions and goodwill are presented. To broaden the context of the subject, specific theories and their counterparts are presented to get both perspectives of a phenomenon. Agency theory and stewardship theory are explained and compared throughout the thesis and the conclusion of this paper is that stewardship theory is more valid when examining Swedish business acquisitions. Other theories such as the resource-based view are explained and connected to business acquisitions and the results of the thesis. Lastly, motives and benefits behind business acquisitions are discussed and conclusions are drawn based on the results of the tests conducted.  Two OLS regressions with corresponding T-tests for verifications showed a nonsignificant relationship between the dependent and independent variables in both tests. This means that there is no statistical significancy between either of the two factors and accounting standards. These findings suggest that there are other factors that are correlated with the number of business acquisitions and value added and explain the variance in these two factors. Some of the observable factors were the size of the firm, return on assets, operating income among others. In conclusion, there were no indications that accounting standards influence the number of business acquisitions nor value added.

Diese kumulative Dissertation besteht aus drei eigenständigen Arbeiten aus dem Bereich der Rechnungslegungsforschung. Die erste Arbeit ist eine Befragungsstudie von 137 internationalen Rechnungslegungsforschern über die Fair-Value-Orientierung von 28 lokalen Rechnungslegungssystemen. Anhand der Umfrageergebnisse war es möglich, einen internationalen Fair-Value Score zu bilden. Dieser zeigt, dass das portugiesische, slowenische und das russische Rechnungslegungssystem am meisten und das österreichische, deutsche und italienische Rechnungslegungssystem am wenigsten Fair-Value orientiert ist. Die zweite Arbeit untersucht die Determinanten der Wahl von Rechnungslegungssystemen mittels eines Prinzipal-Agenten-Models. In dem Model kann ein risikoneutraler Entrepreneur (Prinzipal) mit einem Anreiz zur Konsumglättung zwischen zwei Rechnungslegungssystemen wählen. Das Rechnungslegungssystem wird genutzt, um eine effiziente vertragstheoretische Lösung mit dem Manager herbeizuführen und um Informationen über das Unternehmen für Kapitalmarktteilnehmer bereitzustellen. Die Modellergebnisse zeigen, dass der Entrepreneur eher gewillt ist das Fair-Value-orientierte Rechnungslegungssystem zu wählen, wenn die Bedeutung von Eigenkapitalmärkten steigt, die Opportunitätskosten des Managements steigen, die Produktivität des Managements sinkt und die Qualität des Enforcements von Rechnungslegungsregeln abnimmt. Die empirischen Ergebnisse bestätigen größtenteils die theoretischen Erwartungen. Die dritte Arbeit untersucht, ob die verpflichtende Einführung der IFRS bei gleichzeitiger Anpassung des Enforcements zu einer Verbesserung der Ergebnisqualität geführt hat. Die empirischen Ergebnisse sind uneinheitlich und können daher den vermuteten Effekt nicht bestätigen. / This cumulative PhD-thesis consists of three papers within the field of empirical accounting research. The first paper provides descriptive evidence on the fair value orientation of existing local GAAP systems by surveying the perception of 137 international accounting academics about the fair value orientation of 28 local GAAP systems. The survey results enable us to rank countries’ local GAAP systems by their fair value orientation. The score ranking shows that Portuguese, Slovenian and Russian GAAP are the top three and Austrian, German and Italian GAAP are the bottom three of the fair value orientation. Furthermore, we are able to show that the fair value orientation of IFRS is higher than any of the 28 local GAAP systems. The second paper investigates the determinants of financial accounting regime choice in a principal agent setting. The model considers a risk-neutral entrepreneur who needs financial accounting information for contracting with a managerial agent and for communicating the firm value to a risk-averse secondary capital market. The comparative static results indicate that the preference of the entrepreneur for a fair value accounting regime increases with the relative importance of the secondary capital market and the opportunity costs of the managerial agent, while it decreases with the overall quality of the accounting signal, the effectiveness of the enforcement process and managerial productivity. Empirical evidence, which is based on country-year and country-level and US time series analysis, provides support for most of the theoretical predictions. The third paper investigates whether earnings quality effects are more pronounced post mandatory IFRS adoption in countries that substantially changed their enforcement system of accounting standards in comparison to countries that already had a strict enforcement system in place. The empirical analysis gives inconclusive results for the earnings quality measures.
