This report addresses two key questions for today's top executives: Do acquisitions create value for acquirers? And under what circumstances have acquisitions created the most value for acquiring shareholders?
The authors' analysis of over 1,500 completed deals by non-financial companies in the United States over the past 12 years shows that, at announcement, acquirers' shareholders suffer small losses, on average, in the short term around the initial deal announcement. Over longer intervals, such as one or two years following the announcement of the transaction, acquirers tend to slightly outperform industry peers.
The average or median market response hides tremendous variability in how the market has reacted to individual deals, however. This article provides evidence that the "right" M&A transaction can create substantial value for acquirers. One-quarter of the transactions lead to market-adjusted gains in excess of 5% for the acquirer and oneeighth of the transactions lead to gains in excess of 10% in the short term. However, some deals have also destroyed substantial shareholder value.
Financing structure is a key driver of the stock market reaction. Stock-financed transactions, on average, have a negative stock market reaction, while cash-financed transactions have benefited acquirers in both the short term as well as the long term.
Acquisitions of private companies or assets and units of public companies have consistently generated higher returns for acquirers than purchases of public companies.
Moreover, EPS dilution is not a major driver of how the stock market reacts to a deal. Although "accretive" deals perform slightly better than "dilutive" ones in the short and long run, the difference is small and not statistically significant. Over the long run, acquiring shareholders have benefited the most from deals within the same industry and that avoid targets with relatively optimistic earnings growth projections. 相似文献

This paper develops and analyzes a welfare maximizing model of infant industry protection. The domestic infant industry is competitive and experiences dynamic learning effects that are external to firms. The competitive foreign industry is mature and produces a good that is an imperfect substitute for the domestic good. A government planner can protect the infant industry using domestic production subsidies, tariffs, or quotas in order to maximize domestic welfare over time. As protection is not always optimal (although the domestic industry experiences a learning externality), the paper shows how the decision to protect the industry should depend on the industry's learning potential, the shape of the learning curve, and the degree of substitutability between domestic and foreign goods.Assuming some reasonable restrictions on the flexibility over time of the policy instruments, the paper subsequently compares the effectiveness of the different instruments. Given such restrictions, the paper shows that quotas induce higher welfare levels than tariffs. In some cases, the dominance of the quota is so pronounced that it compensates for any amount of government revenue loss related to the administration of the quota (including the case of a voluntary export restraint, where no revenue is collected). In similar cases, the quota may even be preferred to a domestic production subsidy. 相似文献

This note demonstrates an application of a multilevel multinomial model. We use that model to analyse interviewer effects on various components of unit nonresponse to a face-to-face survey: refusals and noncontacts. The model allows for an analysis of these two interviewer effects and a possible connection between both at the same time. Our results show that both the chances for refusals as for noncontacts are subject to interviewer effects. We also find some evidence for a relation between both interviewer effects: interviewers who obtain more refusals are also more likely to report noncontacts. That result is however at least partly dependent on an outlier, an interviewer with a high number of refusals and noncontacts. 相似文献

Previous studies of the driving times of shopping center patrons have not examined the effect of limited access highways.
This study analyzed the impact of interstate highways on the driving times of 204 shoppers at three medium-sized regional
shopping centers. Those shoppers indicating usage of interstate highways to reach their shopping destinations were significantly
more likely to incur travel times greater than fifteen and twenty minutes than those not using the available interstate roads.
In predicting the drawing power of these shopping centers, factors besides mass were found to be useful. These include square
footage of shopping goods, stores, and number of parking places. 相似文献

In this paper production, trade and welfare effects of European integration are discussed, with particular emphasis on the effects for the EC and EFTA. Insights from previous partial and general equilibrium analyses of the internal market are reviewed, and new model simulations are presented. In addition to the standard experiments of 1992 — as reduced trade costs and as full market integration — for the EC alone, and for the European Economic Area (EEA), an intermediate case, with full integration in the EC but only lower trade costs between the EC and EFTA, is analysed. All cases show that EFTA will benefit significantly from freer trade and closer integration with the EC. With regard to non-European regions, the simulations of European integration show some degree of trade diversion, but stylized model experiments indicate that a successful outcome of the Uruguay-round may more than offset the trade-diverting effects of 1992. 相似文献

Arrow's celebrated theorem of social choice shows that the aggregation of individual preferences into a social ordering cannot make the ranking of any pair of alternatives depend only on individual preferences over that pair, unless the fundamental weak Pareto and non-dictatorship principles are violated. In the standard model of division of commodities, we investigate how much information about indifference surfaces is needed to construct social ordering functions satisfying the weak Pareto principle and anonymity. We show that local information such as marginal rates of substitution or the shapes “within the Edgeworth box” is not enough, and knowledge of substantially non-local information is necessary. 相似文献

The article reports on a methodical part of a combined substantive and methodical investigation experimenting with a new type of Policy Delphi method. The common problem defined for both parts was the question whether Delphi method could be transformed in an instrument of controlling technological change by employees. The question was answered positively by the participating (bank) employees, all union members engaged with an automatisation project, themselves. Self rating scales, an evaluation questionnaire and numerous data collected about the research process showed that the most relevant social categories of participants managed to serve as “experts” according to the high levels of cognition, effort, involvement and self-confidence required in a Delphi research project. Participants with low job level, women and non-trained union members joined in very well. The special steps required to broaden a successful participation of all categories, particular methods and techniques of information transmitting questioning and reporting, did not violate the quality of scientifically valid information gathering. So the result was a practical and scientific instrument. 相似文献

A theoretical housing model is developed embodying the approach of the recent hedonic price literature. Instead of focusing on a scalar “housing service” consumption measure, the model portrays housing as a commodity with two attributes: floor space and yard space. Developers react to a consumer bid-rent function, which relates dwelling rent to floor space, yard space, and location, in choosing the profit-maximizing characteristics of their housing complexes. The spatial behavior of the developer's choice variables is investigated (an interesting question is whether yards are larger farther from the urban center), and a comparative static analysis of the housing market equilibrium is presented. 相似文献
