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...

Mergers that substantially lessen competition are challenged by antitrust authorities. Instead of blocking anticompetitive transitions straight away, authorities might choose to negotiate with the merging parties and allow the transactions to proceed with modifications that restore or preserve...

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...

This paper applies a novel and 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. We analyze the economic effects of the European Commission's merger control decisions and...

This paper takes a look at the effects of mergers in continental Europe over the past 15 years. We use a large panel of data on mergers to test several hypotheses. The effects of the mergers are examined by comparing the performance of the merging firms with control groups of non-merging and/or...

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...
