The Impact of Stricter Merger Control on Bank Mergers and Acquisitions. Too-Big-To-Fail and Competition
The effect of regulations on the banking sector is a key question for financial intermediation. This paper provides evidence that merger control regulation, although not directly targeted at the banking sector, has substantial economic effects on bank mergers. Based on an extensive sample of European countries, we show that target announcement premia increased by up to 16 percentage points for mergers involving control shifts after changes in merger legislation, consistent with a market expectation of increased profitability. These effects go hand-in-hand with a reduction in the propensity ...

Beyond "Horizontal" and "Vertical": The Welfare Effects of Complex Integration
We study the welfare impacts of mergers in markets where some firms are already vertically integrated. Our model features logit Bertrand competition downstream and Nash Bargaining upstream. We numerically simulate four merger types: vertical mergers between an unintegrated retailer and an unintegrated wholesaler, downstream "horizontal" mergers between an unintegrated retailer and an integrated retailer/wholesaler, upstream "horizontal" mergers between an unintegrated wholesaler and an integrated retailer/wholesaler, and integrated mergers between two integrated retailer/wholesaler pairs. We ...

Assessing the Common Ownership Hypothesis in the US Banking Industry
The common ownership hypothesis (COH) states that firms with common shareholders, primarily large asset managers, compete less aggressively with each other. The U.S. banking industry is well suited to assess the common ownership hypothesis, because thousands of private banks without common ownership (CO) compete with hundreds of public banks with high and increasing levels of CO. This paper assesses the COH in the banking industry using more comprehensive ownership data than previous studies. In simple comparisons of raw deposit rate averages we document that the deposit rates of public banks ...

The Impact of Merger Legislation on Bank Mergers
We find that stricter merger control legislation increases abnormal announcement returns of targets in bank mergers by 7 percentage points. Analyzing potential explanations for this result, we document an increase in the pre-merger profitability of targets, a decrease in the size of acquirers, and a decreasing share of transactions in which banks are acquired by other banks. Other merger properties, including the size and risk profile of targets, the geographic overlap of merging banks, and the stock market response of rivals appear unaffected. The evidence suggests that the strengthening of ...

The U.S. banking industry is well suited to assess the common ownership hypothesis (COH), because thousands of private banks without common ownership (CO) compete with hundreds of public banks with high and increasing levels of CO. This paper assesses the COH in the banking industry using more comprehensive ownership data than previous studies. In simple comparisons of raw deposit rate averages we document that (i) private banks do offer substantially more attractive deposit rates than public banks, but (ii) the deposit rates of public banks are similar in markets without CO where a single ...

Estimating the Competitive Effects of Common Ownership
If managers maximize the payoffs of their shareholders rather than firm profits, then it may be anticompetitive for a shareholder to own competing firms. This is because a manager?s objective function may place weight on profits of competitors who are held by the same shareholder. Recent research found evidence that common ownership by diversified institutional investors is anticompetitive by showing that prices in the airline and banking industries are related to generalized versions of the Herfindahl-Hirschman Index (HHI) that account for common ownership. In this paper we propose an ...
