This thesis examines the linkages between macroeconomic variables and the number of domestic Mergers & Acquisitions (M&A) in Sweden during 1998-2011 (in terms of changes). This study treats stationary times series data, from which multiple regression models are assembled. These models include gross domestic product, OMX Stockholm price index, lending rate, money supply, debt rate, consumer confidence, the unemployment rate and capacity utilization as explanatory variables. Aggregate number of M&As is set to the dependent variable. The outcome was that gross domestic product, money supply, unemployment rate and stock prices can help explain fluctuations in M&A activity during different time frames. However, the majority of the explanation for fluctuations in M&A activity lies within factors beyond ourestimation model. Through a Granger-causality test, we establish if the significant variables can help to predict M&A activity and vice versa. During different time periods gross domestic product and unemployment helps in predicting M&A activity. M&A activity also improves the prediction of gross domestic product in some time periods.

Title: M&A activity and the macroeconomic environment - a quantitative study on the impact of the macroeconomic environment on aggregate merger and acquisition activity in the US Background: There is a lack of established theories on what drives M&A activity. A subject that has received much attention in literature but produced few compelling results. The full explanation of the dynamics of aggregate M&A activity has yet to be captured. An explanation which could provide useful insights for central banks, corporate managers and any other parties affected by this prominent feature of the US economy which have come to shape and dominate the corporate landscape. Purpose: The purpose of this thesis is to investigate the relationship between the dynamics of aggregate M&A activity and macroeconomic variables representing the state of the economy in the US. Method: The methodology that is used in the thesis is based on a deductive research approach with a quantitative research design. In addition, the thesis has also made use of a longitudinal panel research. The thesis hypotheses have been formulated using earlier research and existing theories about the subject of mergers and acquisitions as well as macroeconomic factors. Further on, the data set that has been analyzed consisted of 73137 transactions during the time period January 1, 1980 - January 1, 2020. Conclusion: The study finds that there are signs of relationships between macroeconomic variables and aggregate M&A activity, although the precise characteristics of these relationships has not been established. The result of the study indicates that the macroeconomic environment as a whole affects aggregate M&A activity and that it can be an important part of the explanation for the dynamics of aggregate M&A activity. It cannot be established that macroeconomic variables can be used to predict M&A activity, however there are interesting indications suggesting this might be the case.

The perennial controversy in business combinations accounting and its dialectic with stakeholders’ interests under the complexity of the Mergers and Acquisitions (M&A) activity is the centrepiece of analysis in this thesis. It is argued here that the accounting regulation should be as neutral as possible for the economic activity, although it is recognised that accounting changes may result in economic effects. In the case of the changes for business combinations accounting in the USA, lobbying was so fierce that in order to achieve the abolition of accounting choice in M&A accounting, it forced the standard-setter to compromise and to change substantially some of its earlier proposals. Such fierce lobbying cast doubts about whether it was effectively possible to mitigate such economic effects, resulting in a possible impact of the accounting changes on the M&A activity. The occurrence of M&A in waves is yet to be fully theorised. Nevertheless, existing literature established relationships between M&A activity and some key economic and financial factors, and has provided several interesting theories and other meaningful contributions for this thesis. It was therefore possible to examine whether the changes in the accounting rules produced any significant impact on the M&A activity. The findings obtained from the testing of the research hypotheses suggest that the new M&A accounting rules did not result in significant impacts on overall M&A activity. Nevertheless, from the study of managers’ perceptions, and from the examination of annual reports of S&P 500 companies, a considerable impact on the financial reporting was found.
