Does Corporate Diversification Destroy Value? 总被引:15,自引:0,他引:15
We analyze several hundred firms that expand via acquisition and/or increase their number of business segments. The combined market reaction to acquisition announcements is positive but acquiring firm excess values decline after the diversifying event. Much of the excess value reduction occurs because our sample firms acquire already discounted business units, and not because diversifying destroys value. This implies that the standard assumption that conglomerate divisions can be benchmarked to typical stand-alone firms should be carefully reconsidered. We also show that excess value does not decline when firms increase their number of business segments because of pure reporting changes. 相似文献

Consumers are increasingly using technologies such as wearables or mobile apps to achieve their self-improvement goals. Such technologies often contain features that enable social interdependence (competition or cooperation) among users to support them in improving their engagement, performance, and well-being (life satisfaction and personal growth). However, the critical question remains: does competition or cooperation best serve users in attaining these self-improvement goals? Evidence from an online experiment and a field study reveals that competition is more effective in driving performance and personal growth, while cooperation is superior in terms of behavioral engagement and life satisfaction. Furthermore, the results indicate that the effects are mediated by strive for success and fear of failure, two counteracting psychological processes. While competition is the stronger trigger for both pathways, downstream effects vary depending on the self-improvement goal considered. This research thus provides insights into whether and how users can best realize their self-improvement goals using technologies that include social features. 相似文献

The paper examines the monetary policy actions through which central banks in sub‐Saharan Africa have tried to eliminate the negative impacts of the shocks facing their economies. We compare two different monetary policy regimes: a currency board regime (in the CFA zone) and an inflation targeting policy regime (Ghana and South Africa) when central banks respond to demand, supply, and fiscal shocks. We extend the usual forecasting and policy analysis system models to replicate the economic features of these economies during the period 2002–12 and to evaluate the impact of several policies in response to these shocks. We find that both policies are inappropriate in helping the economies escape from the effects of negative demand shocks, both are essential when negative shocks to primary balance occur, while inflation targeting dominates the currency board regime as a strategy to cope with positive shocks to inflation. 相似文献

With increasing pressure to cut costs, both real and immediate, and those forecasted and anticipated, the partnership and collaboration between nursing and finance will continue to take on new challenges. This partnership has historically been strained and does not always come easy due to differences in focus, different priorities, and inadequate communication, listening, and hearing. That needs to change and a strong CNO-CFO partnership is needed. Nursing leaders need to understand and appreciate the financial constraints and balance them with expected outcomes, and financial leaders need to understand and appreciate the core clinical business and what gaps in care mean to the financial viability of the organization and to patient outcomes. One health system developed a platform for change and is dedicated to the hard work involved in continuously working on those partnerships so when it comes to patient quality, safety, and financial performance, nursing and finance leaders are well positioned for future health care challenges. 相似文献

Planning initiatives outside the formal planning system can constitute a favourable environment for implementing and analysing collaborative decision-making processes. The conceptualisation of the decision-making context in the light of the Policy Network analysis helps to better understand the underlining conditions, as well as their influence in the outcomes. In the case under analysis, were the decision-making conditions were of co-responsibility and power-sharing, the challenge has been to warrant the effectiveness of the decisions, which lies, as is argued, in the reliability of the framework for decision-making and in the ability to translate the collaborative participation outputs into actions at different time-frames. Moreover, as the case-study deals with strategic spatial planning, a future oriented approach is needed to warrant the flexibility and robustness of the plan in addressing the uncertainty associated with long term objectives. Those are the critical issues to be handled in the multi-criteria analysis (MCA) framework which sustains the analytical hierarchy process (AHP) that was used to support the decision-making process. 相似文献
