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

Improving children's access to primary and secondary education is a strategic goal for many global development agencies and government policymakers. Nevertheless, there is relatively little research examining how changes in rural school supply affect future labor markets. We leverage variation in the timing and location of secondary school construction in Southern Mexico to identify the effects of school supply on labor outcomes. We find that school construction increases expected education for school-aged children by about 4 years and raises the share of years working in the nonagricultural sector between the ages of 18–22 by 29.8 percentage points. The magnitude of the effects on share of years doing nonagricultural work is smaller for individuals from homes where an indigenous language is spoken. Our findings indicate that rural school construction in less-developed countries can accelerate the transformation from agricultural to nonagricultural economies, but there may be heterogeneous effects across socioeconomic groups and ethnicities.  相似文献

The terms Attention Deficit Disorder (ADD) or Attention Deficit/Hyperactivity Disorder (AD/HD) refer to a neurological impairment that affects the individual's ability to sustain attention and to behave in a calm, rational manner.3Although this disorder has long been considered to be restricted to childhood, recent research has demonstrated that many children carry it over into adult life and take it with them into the workplace. Most U.S. courts have treated AD/HD as a disability covered by the Americans with Disabilities Act (ADA).4However, in the summer of 1999, the U.S. Supreme Court made three decisions that will undoubtedly affect the future status of AD/HD and other impairments under the ADA. This article examines those decisions, how they affect the employment rights of AD/HD-afflicted employees, and the changes they will probably bring to litigation in this area. Because we have many reservations about the court's decisions, we not only voice our criticisms of the decisions, but also offer an alternative approach.  相似文献

The serious leisure inventory and measure (SLIM) was tested with 348 chess players to confirm the factors, assess the effects of method bias, and propose a set of the best-performing items for the 18 factor SLIM. The 54-item SLIM demonstrated acceptable fit and reliability values. The effect of method bias was evidenced in the sample and explained one-third of the variance. Inspection of factor loadings, when controlling for method bias, yielded one best-performing item per factor. Findings indicate method bias continues to be problematic for self-report measures such as the SLIM.  相似文献

Small businesses are the backbone of the economy in many countries. In Europe, for example, small companies represent more than 90 per cent of all companies (e.g., Lukacs, 2005 ). Although these companies represent such an important portion of the economy, few studies have examined their voluntary disclosure decisions. Because small companies have certain unique characteristics compared with their larger counterparts, the general applicability of past voluntary disclosure studies to small companies is questionable. Drawing on agency and proprietary cost theory, this study investigates whether ownership, competition, and accountant factors influence the decision to disclose financially sensitive information on a voluntary basis. Our results (using an e‐mail questionnaire to small private companies in Belgium, n = 1,068) indicate that nearly 40 per cent of the responding companies are not aware of their disclosure behavior. For companies that are aware of their disclosure behavior, the logistic regression analysis demonstrates that factors relating to the separation of ownership and control, namely the type of ownership and number of shareholders, are among the most important determinants in the voluntary disclosure decision of small private companies. Companies with at least one legal entity as an owner of a company are less likely to disclose, while companies with more shareholders are more likely to disclose. We also provide evidence that perceived competition and the default setting of the accounting software used have a significant influence on the voluntary disclosure behavior.  相似文献

For the circular economy to be tenable, consumers need to not only return products after use, but also purchase products that are remanufactured. However, research finds that consumers have a poor opinion of remanufactured products and are typically not prepared to adopt them. Thus, development of the circular economy is dependent upon deeper understanding of consumers’ attitudes and behaviors. Research typically considers either micro‐level or macro‐level factors when assessing consumer perceptions of remanufactured products. The current research incorporates macro‐level factors of price, government incentives and environmental benefits with the moderating influence of micro‐level consumer attitudes to examine consumers’ intention to switch from purchasing new products to remanufactured products. The findings suggest that a consumer's attitude toward remanufactured products is an important moderating factor predicting consumer switching behavior to remanufactured products.

Rock mining operations, including limestone and gravel production, have considerable adverse effects on residential quality of life due to elevated noise and dust levels resulting from dynamite blasting and increased truck traffic. This paper provides the first estimates of the effects of rock mining—an environmental disamenity—on local residential property values. We focus on the relationship between a house's price and its distance from a nearby rock mine. Our analysis studies Delaware County, Ohio, which, given its unique features, provides a natural environment for the valuation of property‐value‐suppressing effects of rock mines on nearby houses. We improve upon the conventional approach to evaluating adverse effects of environmental disamenities based on hedonic house price functions. Specifically, in the pursuit of robust estimates, we develop a novel (semiparametric) partially linear spatial quantile autoregressive model which accommodates unspecified nonlinearities, distributional heterogeneity, as well as spatial dependence in the data. We derive the consistency and normality limit results for our estimator as well as propose a consistent model specification test. We find statistically and economically significant property‐value‐suppressing effects of being located near an operational rock mine which gradually decline to insignificant near‐zero values at roughly a 10‐mile distance. Our estimates suggest that, all else equal, a house located a mile closer to a rock mine is priced, on average, at about 2.3–5.1% discount, with more expensive properties being subject to larger markdowns.  相似文献

This study analyzes Canadian consumer willingness to pay for omega-3 enhanced beef, pork, and chicken. Using a nationwide survey conducted by ACNielsen in 2006 and choice modeling framework, results indicate that smaller household, households with high incomes, and households that have previously purchased an omega-3 product are willing to pay a premium for omega-3 beef, pork and chicken. The results also suggest that consumers that have previously purchased an omega-3 product are willing to pay a higher premium for the respective omega-3 meats compared to households that have never purchased an omega-3 product. Also, premiums are highest for omega-3 beef, followed by omega-3 pork, and last, omega-3 chicken.  相似文献
