Because the break-up of conglomerates typically produces substantial increases in shareholder wealth, many commentators have argued that the conglomerate form of organization is inefficient. This article reports the findings of a number of recent academic studies, including the authors' own, that examine the causes and consequences of corporate diversification. Although theoretical arguments suggest that corporate diversification can have benefits as well as costs, several studies have documented that diversified firms trade at a significant discount from their single-segment peers. Estimates of this discount range from 10–15% of firm value, and are larger for “unrelated” diversification than for “related” diversification. If corporate diversification has generally been a value-reducing managerial strategy, why do firms remain diversified? One possibility, which the authors label the “agency cost” hypothesis, is that top executives without substantial equity stakes may have incentives to maintain a diversification strategy even if doing so reduces shareholder wealth. But, as top managers' ownership stakes increase, they bear a greater fraction of the costs associated with value-reducing policies and are therefore less likely to take actions that reduce shareholder wealth. Also, to the extent that outside blockholders monitor managerial behavior, the agency cost hypothesis predicts that diversification will be less prevalent in firms with large outside blockholders. Consistent with this argument, the authors find that companies in which managers own a significant fraction of the firm's shares, and in which blockholders own a large fraction of shares, are significantly less likely to be diversified. If agency problems lead managers to maintain value-reducing diversification strategies, what is it that leads some of these same firms to refocus? The agency cost hypothesis predicts that managers will reduce diversification only if pressured to do so by internal or external mechanisms that reduce agency problems. Consistent with this argument, the authors find that decreases in diversification appear to be precipitated by market disciplinary forces such as block purchases, acquisition attempts, and management turnover.  相似文献

Using internal records of board meetings, this research explores issues relating to the motivation of directors' action during takeover negotiations. The records relate to a time period when regulation was low and directors had ample opportunity to engage in adverse selection and moral hazard. In such circumstances, it might be supposed that they would have sought to protect their own tenure rather than seek to maximize shareholder wealth by recommending acceptance of a bid. However, in the case study under examination the directors worked hard to maximize the bid price by auctioning the company despite having little equity exposure themselves. The directors also sought to protect the interests of the staff when negotiating with bidders. Intentionally this behaviour was not disclosed to the shareholders and, on occasion, threatened the success of the negotiations. The article concludes that the actions of the directors were motivated by strong reputational effects not widely recognized in the contemporary literature as being a force that powerfully drives corporate governance.  相似文献

New data on Thailand's industrial firms shed light on the originsof the East Asian financial crisis and on the response of themanufacturing sector to the structural adjust-ment program supportedby the international financial institutions. Before the crisis,Thai firms had declining profitability, but they neverthelessmaintained high levels of investment, often in domesticallyoriented areas (notably the auto sector). Thai firms financedthese investments with short-term borrowing from financial institutions,which in turn borrowed short term on foreign markets. That only40 percent of firms provided audited financial statements totheir banks meant that the financial sector had poor informationfor assessing the true riskiness of these investments. The financialstructure was thus vulnerable even to small shocks. How well did the adjustment program deal with the crisis? Thaifirms had difficulty increasing their exports quickly becauseof investment in the wrong sectors, a decline in regional demand,and bottlenecks that included red tape and poor customs administration.Because of the poor export response, the brunt of adjustmenthad to come through compression of demand and of imports. Inretrospect, the macroeconomic program— which assumed quickexport recovery— was too tight.   相似文献

This paper examines whether investors’ valuations of cash and share-put warrants are influenced by their potential differential effect on firm solvency. It is motivated by the enactment of SFAS 150, which requires that all contingent put warrant obligations be classified as balance sheet liabilities regardless of put type. Consistent with the critics of SFAS150, we show that market participants differentially value cash and share-puts based on their solvency characteristics beyond the firm’s recorded assets and liabilities. Our results add to existing capital structure literature by suggesting that complex financial instruments (such as cash and share-puts) be reported separately from each other on a firm’s balance sheet.

Demographic change, social security systems, and savings   总被引:2,自引:0,他引:2  
In theory, improvements in healthy life expectancy should generate increases in the average age of retirement, with little effect on savings rates. In many countries, however, retirement incentives in social security programs prevent retirement ages from keeping pace with changes in life expectancy, leading to an increased need for life-cycle savings. Analyzing a cross-country panel of macroeconomic data, we find that increased longevity raises aggregate savings rates in countries with universal pension coverage and retirement incentives, though the effect disappears in countries with pay-as-you-go systems and high replacement rates.  相似文献

Life table analysis and other mortality methods apply well to end points other than mortality. This paper demonstrates the application of mortality experience methodology to the recurrence of breast cancer and/or new primaries in women previously diagnosed with primary breast cancer. Specific recurrence rates are broken out by duration as well as attributes available at the time of primary breast cancer diagnosis: stage, histology, age band, and year of diagnosis. Use of attained age is demonstrated to control for the effect of aging over long durations. Breast cancer recurrence is shown to drop to a relatively low rate compared with the rate of new primary occurrence.  相似文献

We present four stylized facts about the Dot Com Era: (1) there was a widespread belief in a Get Big Fast business strategy, (2) the increase and decrease in public and private equity investment was most prominent in the Internet and information technology sectors, (3) the survival rate of dot com firms is on par with or higher than other emerging industries, and (4) firm survival is independent of private equity funding. To connect these findings we offer a herding model that accommodates a divergence between the information and incentives of venture capitalists and their investors. A Get Big Fast belief cascade could have led to overly focused investment in too few Internet startups and, as a result, too little entry.  相似文献
