Do Depositors Benefit from Bank Mergers? An Examination of the UK Deposit Market

This study examines whether depositors benefit from bank mergers Specifically, do horizontal retail bank mergers influence the availability and interest rates of deposit services? This examination is important, as the effect of mergers on customers is a primary merger assessment criterion in the European Union and the United States. The research question is addressed by considering 57 UK banking mergers over the period 1989–2008. It is reported that different deposit services and deposits of different values face statistically insignificant levels of interest-rate change after mergers. The availability of notice deposit services for low and high levels of investment are reduced after mergers and are largely unchanged for other deposit services. It is concluded that UK depositors benefit little from bank mergers, and different types of depositor face differences in the availability of deposit services after mergers.     

Evidence on real gains in corporate acquisitions

This study examines the change in operating performance of firms which merge for a sample of 324 combinations which occurred between 1967 and 1987. The results indicate that the performance of the merged firms typically improved following their combination. The results are not sensitive to factors such as offer size, industry relatedness between the bidder's and the target's businesses or bidder leverage. Separately, a positive association was found between the abnormal revaluation of the firms involved around the merger and the changes in operating performance observed. We conclude that the results documented in Healy et al. (1992) for a sample of 50 large mergers which occurred during the period 1979 through mid-1984 are not sensitive to sample size or to the period they investigated. The conclusions presented provide additional support for the idea that takeovers are motivated by expectations of improved performance due to the realization of synergistic benefits.     

Have Supermarket Mergers Raised Prices? An Event Study Analysis

Antitrust enforcement of supermarket merger activity during the late 1980s and early 1990s was less stringent than it had been before or has been since. For six announcements of supermarket acquisitions during this period, this study examines the abnormal stock returns of rival firms to determine if investors believed these acquisitions would lead to higher retail prices.These abnormal returns imply that investors expected that the average retail price change associated with these types of acquisitions ranges from a 0.12% decrease to a 0.05% increase. Thus, our results suggest that investors generally did not view these acquisitions as anticompetitive.     

A comparative analysis of the market-based and accounting-based performance of diversifying and non-diversifying acquisitions in Hong Kong

This paper investigates the short-term return performance and long-term operating performance of 36 partial mergers in Hong Kong during the period 1984–1996. We first conduct an event-study to evaluate the short-term market performance of the target, the bidder and a simulated combined portfolio consisting of both firms involved in the acquisition. The second method provides long-term performance indicators based on composite indices created from key financial ratios. The results of the event-study indicate that there are immediate share price gains to the target, acquiring and combined firms around the time the acquisition is announced. However, the long-term accounting-based performance analysis does not show a significant improvement in the 2 years following the acquisition for both the target and acquiring firms. No correlation is found between the short-term returns and the long-term performance indicators. These findings support the more recent literature on the potential benefits of diversification, and the view that diversifying acquisitions perform better than related acquisitions.     

Expert Report in United States v. Interstate Bakeries Corp. and Continental Baking Co.

This is a condensed antitrust analysis of the proposed merger of two leading bakers of white pan bread. The traditional structural analysis is supplemented by merger simulation, which estimates the likely price effects of the merger.     

Specialization dynamics

This paper proposes a new empirical framework for analyzing specialization dynamics. A country’s pattern of specialization is viewed as a distribution across sectors, and statistical techniques for analyzing the evolution of this entire distribution are employed. The empirical framework is implemented using data on 20 industries in seven OECD countries since 1970. We find substantial mobility in patterns of specialization. Over time horizons of 5 years, this is largely explained by forces common across countries, including world prices and common changes in technical efficiency. Over longer time horizons, country-specific changes in factor endowments become more important. There is no evidence of an increase in countries’ overall degree of specialization.     

Predicting the Price Effect of Mergers with Polynomial Logit Demand

We propose a polynomial logit model to quantify the price effects of mergers in a static Nash setting. The proposed model is parsimonious in parameters and is shown to have excellent predictive power, rivaling the in-sample and out-of-sample predictive accuracy of the widely-used AIDS model.The analysis, using actual scanner data on bread sales, demonstrates that a linear logit model is likely to over-estimate the merger price effect.     

Simulating Partial Asset Divestitures to 'Fix' Mergers

In this paper, we apply and extend merger simulation methodology to analyze the effectiveness of partial divestitures as a 'fix' to remedy the possible anticompetitive effects of horizontal mergers. Typically, antitrust agencies require merging firms to divest assets so that the status quo before the merger is restored, that is, they favor a 'full divestiture'. We focus on the effectiveness of a partial divestiture as an antitrust remedy (where a subset of products owned by the merging firms is spun off). Although this is not the type of full divestiture favored by antitrust agencies, we argue here that a partial divestiture could leave consumers better off after the merger than they were before - under certain conditions. Using a real-world example, we show how divesting a relatively close substitute creates competition that offsets the anticompetitive effects of combining products that are relatively distant substitutes. This result stands even when the divestee is moderately inefficient.     

An Introduction to the Symposium on the Use of Simulation in Applied Industrial Organization

Simulation offers a rigorous methodology for addressing policy or litigation issues that require a comparison of an observed state of the world with an unobserved one. Simulation employs a calibrated, structural oligopoly model to describe the unobserved state of the world. Calibration involves reliance on real-world observations to set the key parameter values in the model. Simulation is an increasingly important tool of the industrial organization economist, particularly in analyzing the competitive effects of mergers. Papers in this symposium illustrate merger simulations in a variety of contexts and one other application of simulation.     

Alliances,Acquisitions and Multinational Advantage

This paper reviews recent empirical evidence to assess the implications of alliance formation and increasing merger and acquisition activity of multinationals in the context of the eclectic paradigm. Specifically, the paper will concentrate on the performance implications of international expansion via alliances and mergers, and their relationship to the so-called asset-augmenting foreign direct investment. It has been argued in the literature that the way in which multinationals are able to build on their existing advantages and to add to them by virtue of their international activities confers specific benefits to multinationality. We argue that the growth of cross-border acquisitions and alliances as modalities for international expansion has resulted from the continuing convergence of value-adding capabilities within the Triad, and while such activity can help to augment the asset base of the investing firms, it also has potentially anti-competitive implications.     

Competition in the Pharmaceutical Industry: The Case of PAH Drugs

The nature and extent of competition between different therapies for a given medical condition often is an important and controversial issue in both antitrust cases and general strategic analysis in the pharmaceutical industry. The market for pulmonary arterial hypertension (‘PAH’) therapies provides an interesting case study for analyzing these issues. An event study analyzing how the stock prices of PAH therapy providers respond to competitive developments in the industry sheds light on the nature of competition among different types of therapies. The results support the view that the strength of competition between any two drugs for the same condition can vary greatly depending on factors such as the stage of the patient’s disease, the mode of drug delivery, the mechanism of action, convenience/ease of use and other characteristics.     

The role of information technology systems in the performance of mergers and acquisitions

Mergers and acquisitions (M&As) are an important tool for improving a firm's competitive positioning and performance. Despite M&As’ promise, however, they often fail to meet performance goals. Challenges often arise when managers try to integrate two companies’ information technology (IT) systems, and the difficulties encountered often create both short- and long-term performance problems for companies. To help address these challenges, we highlight important issues that managers involved in M&As must consider. We also present some best practices that managers should follow to improve the odds of successful IT integration.     

Maturing born globals and their acquisitive behaviour

Born globals are becoming more common in our interconnected world. While a body of knowledge exists regarding the establishment and early growth of born globals, we know less about how these companies develop. Arguing that acquiring new knowledge, technologies, and products will enable companies to survive beyond their initial success, the current study specifically aims to explore the value of technology-motivated acquisitions, and their effect on performance. To this end, the study employs a hybrid methodology; statistically studying 108 acquisitions conducted by 45 maturing, technology-based born globals in Israel over a period of 10 years, and further substantiate the findings with an in-depth case analysis of four sample companies. The results indicate that technology-motivated acquisitions are valuable in terms of both financial performance and independent survival, but that there likely exists an optimal threshold, indicating that such a strategy, though beneficial, should be carefully managed.     

Supramonopoly: Theory and Evidence from the US Air Passenger Service Markets

A supramonopoly is the market structure of a homogeneous good that is priced higher than the monopoly level. We present evidence of supramonopoly in the US air passenger service. For four airline mergers during the period of 1993 to 2009, we identify routes that dropped fares for no other reason than the increase in market power due to merger. Therefore each of those routes had fare higher than the monopoly level before the merger to monopoly. We explain supramonopoly as the result of a cartel with strongly punitive matching rules. We also discuss the striking implications for antitrust and regulatory policies.     

Customer reactions to acquirer-dominant mergers and acquisitions

This article investigates consumer reactions to acquirer-dominant mergers and acquisitions (M&As) from the perspective of the (smaller) target brand and explores how marketing actions can mitigate negative effects. The findings from five studies show that consumers tend to react negatively to M&As by devaluing the acquirer brand, increasing their intention to switch, and adjusting their attitudes toward the target brand upward. We suggest that psychological reactance is a mediator of the negative effects of merger information on customers' attitudes and switching intentions. We also demonstrate that brand managers can attenuate reactance by involving consumers in merger decisions, thus providing important managerial implications for M&A decisions and processes.
