This paper examines whether the higher profitability and valuation of family firms is related to differences in production technologies and production efficiency. Using data on S&P 500 manufacturing firms, we find that family firms are more productive than comparable non-family firms. Furthermore, our results show that the production technologies of family and non-family firms do not differ per se, thereby suggesting that the differences in the level of production output are caused by higher production efficiency of family firms. These findings indicate that the superior performance of family firms is related to their more efficient use of labor and capital resources.  相似文献

This article contrasts the flexibility of Chinese and Indian urban hospitals and the security of nurses. The study draws on a survey of 55 urban hospitals, and finds that national context generates different flexibility–security outcomes even when workers with similar skills are considered. Our findings support claims that China is constructing a flexibility–security regime that aims to promote both security and flexibility, and that India remains attached to employer‐based social protection, but challenges the claim that economic growth is higher in China because India's employers have relatively less capacity to utilize labour‐time as they wish.  相似文献

Despite the voluminous and growing literature on financial constraints, the origins of the constraints are hardly ever empirically analyzed. This paper offers such an analysis. We study, in particular, the empirical prevalence of adverse selection and moral hazard in capital markets using a unique survey data on Finnish small and medium-sized enterprises (SMEs). The survey data suggest that adverse selection is empirically more prevalent than moral hazard in the capital markets that the SMEs face. We also find that of the variables indicating the presence of adverse selection and moral hazard, the former has more explanatory power in regressions modeling the availability of external finance to the SMEs than the latter. Finally, we document that our proxies for adverse selection and moral hazard are inversely related to the age of firms, just like Peter Diamond’s (1989) model predicts.  相似文献

For a company planning to become a mobile operator, two alternative ways to enter the market exist. In addition to the traditional way of acquiring a spectrum license and building a mobile network, market entrance is also possible by becoming a virtual operator and utilizing the existing networks of incumbent operators. Potentially, virtual operators will have an important role in shaping the mobile market structure and competition. In this paper, techno-economic modeling methods are used to analyze the position of virtual operators in the mobile communications industry. Four alternative virtual operator scenarios are constructed and analyzed using a linear, deterministic, and quantitative techno-economic model. The results highlight the importance of wholesale contracts with incumbent mobile network operators in determining the virtual operators’ business profitability. Unbalance in termination prices between fixed and mobile networks is shown to give incentives for virtual operators to invest in their own network infrastructure.  相似文献

Seit 1997 wurden rund 700 000 Wohnungen aus ?ffentlicher Hand privatisiert. Welche Auswirkungen hat diese Ma?nahme auf den Wohnungsmarkt? Ist es aus sozialpolitischen Gründen notwendig, dass Wohnungen in ?ffentlichem Besitz verbleiben? Kann die sozialpolitische Komponente auch mithilfe von Belegungsrechten gel?st werden?

I decompose the earnings variance of Finnish male and female workers into its permanent and transitory components using the approach of Baker (J Labor Econ,15:338–375, 1997) and Haider (J Labor Econ, 19:799–836, 2001) in the spirit of scientific replication. I find that the increasing earnings inequality of men and women is driven by both the transitory and permanent components of earnings. In addition, I find considerable differences in the earnings dynamics of men and women, that have been largely neglected in previous studies of earnings dynamics. The inequality among men is dominated by the permanent component. Conversely, permanent and transitory components are of comparable magnitudes to women. As a corollary, men experience more stable income paths but display larger permanent earnings differences. Women, on the other hand, face more unstable earnings profiles but show smaller permanent differences in earnings.  相似文献

Expenditure for the Common Agricultural Policy (CAP) has been in the centre of recent policy debate in the preparation of the Financial Framework for the period 2014–2020. Expenditure has generally been considered as the necessary costs for the achievement of the CAP objectives. The authors of this article argue that expenditure is not equal to the economic costs of a policy. Moreover, they claim that the main part of CAP expenditure is not well targeted for the achievement of the CAP’s objectives. The bulk of expenditure is for direct payments tied to agricultural land and, hence, contributes little if anything to CAP’s objectives as laid down in the treaties of the European Union or officially articulated elsewhere.  相似文献

The debt brake for the German Länder, which forbids them from taking on new net debt beginning in 2020, has two major shortcomings. First, the Länder do not have tax autonomy. In fiscal crises, they can only adjust on the expenditure side, not on the revenue side. Given the fact that most expenditure is predetermined by law, in such a crisis, a balanced budget without new debt would hardly be feasible. Second, it is not taken into account that, in particular in small regional units, large investments can hardly be financed by current expenditure. Thus, there is a very high probability that at least some Länder will still take on new net debt after 2020 and, therefore, violate the rules of the debt brake.  相似文献
