We quantify the impact of merger activity on productive efficiency. We develop and calibrate a dynamic industry-equilibrium model that features mergers, entry, and exit by heterogeneous firms. Mergers affect productivity directly through realized synergies, and indirectly through firms'...

This paper assesses whether cross-border M&A decisions exhibit network effects. We estimate exponential random graph models (ERGM) and temporal exponential random graph models (TERGM) to evaluate the determinants of cross-country M&A investments at the sectoral level. The results show that...

Firms that face high ambiguity—Knightian uncertainty—reduce organic investments and increase the likelihood, count, and dollar value of merger and acquisition bids. Conversely, firms that face low ambiguity are likely targets. The probability and speed of deal completion increase in the...

We directly study the information gathering process around a merger announcement by using the IP addresses accessing Form 8-K filings for merger agreements. This allows us to measure who pays attention to the announcement, how attention varies across mergers, and if this attention is related to...

We study mergers in a market where N firms sell a homogeneous good and consumers search sequentially to discover prices. The main motivation for such an analysis is that mergers generally affect market prices and thereby, in a search environment, the search behavior of consumers. Endogenous...

This paper studies the incentives to merge in a Bertrand competition model where firms sell differentiatedproducts and consumers search for satisfactory deals. In the pre-merger symmetricequilibrium, the probability that a firm is the next one to be visited by a consumer is equal acrossfirms not...

We analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits from collaborations arise by sharing knowledge about a cost-reducing technology. By forming collaborations, however, firms also change their own competitive position in the...

We study mergers in a market where N firms sell a homogeneous good and consumers search sequentially to discover prices. The main motivation for such an analysis is that mergers generally affect market prices and thereby, in a search environment, the search behavior of consumers. Endogenous...

This paper studies the incentives to merge in a Bertrand competition model where firms sell differentiated products and consumers search the market for satisfactory deals. In the pre-merger market equilibrium, all firms look alike and so the probability a firm is next in the queue consumers...
