We analyze the impact of corporate governance institutions, ownership structures and external capital market constraints on company returns on investment by using a sample of more than 19,000 companies from 61 countries across the world. We show that (1) of these three sets of institutions, the...

This paper analyzes the effects of mergers around the world over the past 15 years. We utilize a large panel of data on mergers to test several hypotheses about mergers. The effects of the mergers are examined by comparing the performance of the merging firms with control groups of nonmerging...

This paper applies a novel methodology to a unique dataset of large concentrations during the period 1990-2002 to assess merger control's effectiveness. By using data gathered from several sources and employing different evaluation techniques, we analyze the economic effects of the European...

Using a sample of 167 mergers during the period 1990-2002 involving 544 firms either as merging firms or competitors, we contrast a measure of the merger's profitability based on event studies with one based on accounting data. We find positive and significant correlations between them when...

This paper applies an intuitive approach based on stock market data to a unique dataset of large concentrations during the period 1990-2002 to assess the effectiveness of European merger control. The basic idea is to relate announcement and decision abnormal returns. Under a set of four...

A large number of empirical studies in the U.S. report that there is no cross-sectional relationship between board composition and firm performance. On the other hand, a relatively small but growing literature on boards in emerging market corporations shows that a higher level of board...

Using average performance measures – as the literature does - to investigate the relation between ownership structure and performance suffers from severe drawbacks. We propose a marginal Tobin's q and argue for its superiority

We analyze a unique source of media data to assess the influence of different topics of corporate news on costs of financing for a sample of large European and US firms from 2006 to 2016. We distinguish between volume (number of news), tonality (positive, neutral, negative), source (financial...

This paper presents empirical evidence about the ability of event studies to capture future mergers' profitability measured by accounting data. We use a sample of large horizontal concentrations during the period 1990-2002 involving 459 firms either as merging firms or competitors, and contrast...

One of the most conspicuous features of mergers is that they come in waves, and that these waves are correlated with increases in share prices and price/earnings ratios. We test four hypotheses that have been advanced to explain merger waves: the industry shocks, q-, overvaluation and managerial...
