Mergers and acquisitions represent a complex process of buyout of one company by another one and a subsequent process of reciprocal merge of companies to one successive company. It constitutes in a common business experience a frequently used tool designated to ensure a company growth and to reach a main entrepreneur goal - profit maximization. This effect may be achieved due to the fact that mergers and acquisitions facilitate to enter new markets easily to some extend or to gain access to new product line or to access new technology or know how and finally to improve competitiveness by attaining sufficient size of entrepreneurship or by implementation of economies of scale. To execute such transactions successfully and to maximize all positive effects, one has to take into account several various economic and legal aspects. This transaction is also very complicated and comprises many partial steps emerging from both legal requirements and requirements based on common business experience. On that account the transaction represents also array of risks that have to be minimized. Therefore it is possible that a preparation and implementation of mergers and acquisitions may be perceived from both legal point of view and economic point of view, where each has its own specifics. A goal of this thesis is...

Thesis advisor: Michael D. Grubb / The aim of this paper is two-fold: 1) to explore the ex-ante relatedness of merging pharmaceutical companies and 2) to study the ex-post effects of mergers on R&D innovation and drug prices, where innovation is quantified by the number of patents granted. Annual firm-specific financial and patent data in this study were obtained for years between 1987 and 2014, while quarterly drug price data spanned from 2006 Q1 to 2015 Q1. The empirical results suggest that on average, heightened M&A activity leads to diminished R&D output and higher drug prices. These results are confirmed using time series models and by comparing post-merger performance of merged firms to that of their respective control groups through a propensity score matching method. / Thesis (BS) — Boston College, 2015. / Submitted to: Boston College.

This paper examines the relationship between the quality of accountings earnings and long-run performance for South African acquirers in the context of market-to-book value classifications. Glamour acquirers show significant earnings momentum prior to acquisition; however this momentum is not sustainable. In the period after the acquisition glamour acquirers exhibit a decreasing earnings trend and it is found that South African value acquirers outperform value acquirer’s post-acquisition. This paper does not however identify the determinant of this phenomenon as the hypothesis that the pre-acquisition earnings momentum of glamour acquirers is in part bolstered by their aggressive investments is rejected.

This research contributes to the much-debated literature existing on the relationship between the economy, merger and acquisitions (M&A), and investors’ behaviour by empirically examining the relationship between aggregate M&A transactions, Real GDP and the stock market in the top nine countries with respect to M&A activity globally from the period 1999-2018. Interestingly, according to the cross-sectional dependence and slope heterogeneity tests conducted, the research finds that when a specific country's stock market, Real GDP or M&A activity is affected or influenced in some way, this may also have an affect or influence on the other countries considered in this research as well. Each of the nine countries have some common economic characteristics. Additionally, each country has its system with reference to how the stock market index(s), economic activity and M&A activities influence each other and operate individually. This indicates that an economic relationship between the variables in one country may not be replicated by the others. Furthermore, in a country-by-country causality analysis using the Toda and Yamamoto (1995) approach, the research finds considerable evidence in support of the behavioural school of thought where investors’ behaviour and M&A activity seem to influence each other. Out of the nine countries investigated, six countries support the behavioural school of thought, i.e., show strong to moderate causality between M&A activity (number or value) and stock market price index. On the other hand, with reference to the neoclassical theory, surprisingly, there seems to exist a relationship between M&A activity and economic activity where M&A activity (number or value) leads economic activity in two out of the nine countries investigated. Finally, the research also suggests that economic activity seems to have an impact on how investors behave in six out of the nine countries investigated.
