We study holdings in M&A targets by financial conglomerates which affiliated investment banks advise the bidders. We show that advisors take positions in the targets before M&A announcements. These stakes are positively related to the probability of observing the bid and to the target premium....

This paper documents that at the individual stock level insiders sales peak many months before a large drop in the stock price, while insiders purchases peak only the month before a large jump. We provide a theoretical explanation for this phenomenon based on trading constraints and asymmetric...

Fundamental information resembles in many respects a durable good. Hence, the effects of its incorporation into stock prices depend on who is the agent controlling its flow. Similarly to a durable goods monopolist, a monopolistic analyst selling information intertemporally competes against...

It is commonly perceived that firms do not want to be outsiders to a merger between competitor firms. We instead argue that it is beneficial to be a non-merging rival firm to a large horizontal merger. Using a sample of mergers with expert-identification of relevant rivals and the event-study...

In many instances, 'independently-minded' top-ranking executives can impose strong discipline on their CEO, even though they are formally under his authority. This paper argues that the use of such a disciplining mechanism is a key feature of good corporate governance. We provide robust...

There is diverging empirical evidence on the competitive effects of horizontal mergers: consumer prices (and thus presumably competitors' profits) often rise while competitors' share prices fall. Our model of endogenous mergers provides a possible reconciliation. It is demonstrated that...

Most empirical studies that evaluate motives and gains in M&A conclude that acquirers at best do not lose from the deal while targets obtain positive gains. With a database containing merging firms’ characteristics and final bids, we propose a structural approach to infer acquirers’ gains...

Firms that buy distressed and bankrupt companies or some of these companies’ assets earn excess returns that are at least 1.6 percentage points higher than when they make regular acquisitions. These returns come at the expense of the target firm’s shareholders, while overall wealth gains are...
