The purpose of this report is to contribute to the analysis of two questions. Should a merger control system take into account efficiency gains from horizontal mergers, and balance these gains against the anti-competitive effects of mergers? If so, how should a system be designed to account for...

Investment liberalizing countries are often concerned that cross-border mergers & acquisitions, in contrast to greenfield investments, might have an adverse effect on domestic firms and consumers. However, given that domestic assets are sufficiently scarce, we identify a preemption effect and an...

This paper proposes a cross-border M&A model with financially constrained owners in which the identity of the buyer and seller can be determined. We show that policies blocking foreign acquisitions to protect the domestic industry can be counterproductive. Foreign acquisition can increase the...

This report studies the importance of efficiency gains from horizontal mergers. A general theme throughout this report is that efficiency gains, and their pass-on to consumers, may vary substantially from merger to merger. For this reason it seems appropriate to reconsider current practice in...

Anticompetitive mergers increase competitors' profits, since they reduce competition. Using a model of endogenous mergers, we show that such mergers nevertheless may reduce the competitors' share-prices. Thus, event-studies can not detect anti-competitive mergers. 

We investigate the interaction between cross-border acquisitions and greenfield entry in a multi-firm setting. It is shown that the net profits of the acquirer may decrease when the acquisition gives the acquirer a strong position in the product market, relative to greenfield entrants. The...

We propose a model of investments prior to corporate ownership changes. We derive conditions under which the selling of a firm triggers overinvestment by both the seller and the buyer prior to the asset transfer. In a setting with Cournot competition, we show that these incentives can drive the...

Investment liberalizing countries are often concerned that cross-border mergers & acquisitions might have an adverse effect on domestic firms and benefit multinational enterprises (MNEs). However, given that domestic assets are sufficiently scarce, we identify a preemption effect and an asset...

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...
