The objective of this paper is to contribute to the understanding of the supervisory role of the board of directors in the context of mergers and acquisitions (M&As). We focus our study on the European case, for which there is no previous exhaustive evidence on this topic. Using information on 985 mergers and acquisitions carried out over the period 2003–2016 by companies in the major European countries, we analyze the influence of supervisory capacity of the board (small size, higher proportion of outsiders and separated Chairperson-CEO positions) on acquirer returns, differentiating between Anglo-Saxon and continental European contexts. Our results confirm that the effectiveness of corporate governance practices depends strongly on their fit with the broader institutional context. Specifically, we find that a smaller size of the board of directors and the separation of the positions of Chairperson and CEO lead to higher acquirer returns in European Anglo-Saxon countries. By contrast, we do not find evidence that any proxy of supervisory capacity of the board significantly improves acquirer returns in the rest of countries. 相似文献

In 2015, Swiss voters had the opportunity to impose a tax on the super rich in a popular vote and thereby fund a redistributive policy. However, a large majority voted against its seemingly obvious self-interest and rejected the tax. We propose an explanation for this puzzling outcome, bridging the usually separate behavioralist and institutionalist perspectives on the politics of inequality. We start from the observation that political economy tends to neglect processes of preference formation. Theorising preferences as socially constructed, we show that interest groups played a major role in shaping the outcome of the vote. Business frames were multiplied through allied parties and the media and had a major impact on individual voting behaviour. In addition, we demonstrate that interest groups representing business interests derive the content of their communication from business’s structurally privileged position in the capitalist economy. Specifically, creating uncertainty about possible perverse effects of government policies on jobs and growth is a powerful tool to undermine popular support. Frames based on this structural power ultimately explain why the Swiss refrained from ‘soaking the rich.’ 相似文献

The reputation of firms for being environmentally friendly and socially responsible is a key purchase driver for sustainable products. However, the commitment of firms to sustainability varies – some firms are founded on strong environmental and social principles; other more traditional firms are built on strong product/brand focus and are not known for sustainability. In response to market trends, many traditional firms are introducing sustainable products to their portfolios. We argue that the firm’s sustainability reputation (FSR) will influence consumer purchase with respect to equally sustainable products from different firms. Two choice studies demonstrate that FSR favors sustainable product choice when the consumer decides between equally sustainable products. However, FSR affects the choice only for sustainable products and not regular products and does so only for consumers that construe sustainability at a high (abstract) level. Retailers should pay attention to the role that FSR plays in consumer response when they select sustainable products to sell. 相似文献

Major changes are underway in the U.S. retail banking sector toward heavy investments in technology and fewer in personnel. Using the 2017 survey of household economics and decision‐making (SHED) (n = 11,359), we examine the relationship between saving behavior related to emergency, long‐term and periodic expenses and personal, technological, and hybrid bank account access methods. Binary logistic regression models were used to estimate the odds of reporting various saving behaviors in relation to various banking access methods. Findings suggest that the personal access method is positively associated with savings behavior for periodic expenses for the general population, and negatively associated with emergency savings in people with lower education attainment. Technology is associated with all types of saving behavior, while the hybrid access method is associated only with saving for periodic expenses. As investments in self‐service technology increase, the importance of access methods to savings behavior must be considered. 相似文献

Little research has investigated the effect of ownership identity (or type) and corporate philanthropy experience on giving. In this research, relying on legitimacy theory, we first assess the effect of ownership identity on corporate philanthropy (CP) in the context of the 2008 earthquake in China. Then we explore moderation effects of firms' prior CP experience and size as proxies for perceived legitimacy on owners' efforts at increasing giving and legitimacy. We find that state and CEO ownership are deterrents, while non‐SOE and institutional ownership enhances giving probability and amount. In addition, there is evidence that firm size and prior CP weaken the effects of institutional ownership on CP. This study provides a complete assessment of owner behaviour. Copyright © 2018 ASAC.

This paper discusses the determinants of China’s outward foreign direct investment (OFDI) with a special focus on the role of government policy. In particular, we investigate the types of policies that are most influential in promoting OFDI. Our main contribution is to analyse, for the first time, China’s OFDI policies by means of quantitative indicators. We refine policies definitions and distinguish between Regulation Policies, Service Policies, Promotion Policies and Supervision Policies, and we develop a methodology for collecting, screening and coding policies; then we create new indices to capture different types of policies. We find that Regulation Policies, Service Policies and the general attitude of the government have significant effects on China’s OFDI at the national level. 相似文献

This study back-tests a marginal cost of production model proposed to value the digital currency Bitcoin. Results from both conventional regression and vector autoregression (VAR) models show that the marginal cost of production plays an important role in explaining Bitcoin prices, challenging recent allegations that Bitcoins are essentially worthless. Even with markets pricing Bitcoin in the thousands of dollars each, the valuation model seems robust. The data show that a price bubble that began in the Fall of 2017 resolved itself in early 2018, converging with the marginal cost model. This suggests that while bubbles may appear in the Bitcoin market, prices will tend to this bound and not collapse to zero. 相似文献
