Parents’ influence on and monitoring of children’s television use has been investigated intensely. In recent years international research has identified different environmental and family factors which influence active mediation, restrictive mediation, and co-viewing. However, there has been no systematic simultaneous comparison of the impact of these factors in German-speaking Switzerland. Therefore the present study analyzes the impacts of parental attitudes as well as family and environmental factors on parental mediation of children’s TV use simultaneously. 252 parents of children aged 3 to 14 answered questions concerning the impact factors, their mediation behaviour as well as children’s media use. Results confirm findings from international research: Most important for parental mediation styles are parental attitudes and the family communication style as well as children’s age. Structural and other sociodemographical factors seem to be less important. 相似文献

The article analyzes the possibility of reaching an equilibrium in a market of marine mutual insurance syndicates, called Protection and Indemnity Clubs, or P&I Clubs for short, displaying economies of scale. Our analysis rationalizes some empirically documented findings, and points out an interesting future scenario. We find an equilibrium in a market of mutual marine insurers, in which some smaller clubs, having operating costs above average, may grow larger relative to the other clubs in order to become more cost effective, and where medium to larger cost‐efficient clubs may stay unchanged or some even downsize relative to the others. Some of the very large clubs suffering from diseconomies of scale may have a motive to further increase relative to the other clubs. According to observations, most clubs have, during the last decade, expanded significantly in size measured by gross tonnage of entered ships, some clubs have merged, but very few seem to have decreased their underwriting activity, in particular none of the really large ones. The analysis points to the following future scenario: The small and the medium to large clubs converge in size, while there is a possibility for some very large clubs to be present as well. 相似文献

A Long-Run Non-Linear Approach to the Fisher Effect 总被引:1,自引:0,他引:1

We argue that the empirical failure of the Fisher effect found in the literature may be due to the existence of non-linearities in the long-run relationship between interest rates and inflation. We present evidence that, for the U.S. during the 1960–2004 period, the Fisher relation presents important non-linearities. We model the long-run non-linear relationship and find that an ESTR model for the pre-Volcker era and an LSTR model for the post-Volcker era are able to control for non-linearities and constitute long-run co-integration vectors. Monte Carlo evidence produces support for the hypothesis that non-linearities may also be responsible for the less than proportional coefficients of inflation usually found in the linear specifications. 相似文献

We study empirically the macroeconomic effects of an explicit de jure quantitative goal for monetary policy. Quantitative goals take three forms: exchange rates, money growth rates, and inflation targets. We analyze the effects on inflation of both having a quantitative target and hitting a declared target. Our empirical work uses an annual data set covering 42 countries between 1960 and 2000, and takes account of other determinants of inflation (such as fiscal policy, the business cycle, and openness to international trade) and the endogeneity of the monetary policy regime. We find that both having and hitting quantitative targets for monetary policy is systematically and robustly associated with lower inflation. The exact form of the monetary target matters somewhat (especially for the sustainability of the monetary regime) but is less important than having some quantitative target. Successfully achieving a quantitative monetary goal is also associated with less volatile output. 相似文献

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

This article develops a consumption-based valuation model that treats earnings and cash flow as complementary information sources. The model integrates three ideas that do not appear in traditional valuation models: (i) earnings provide information about future shocks to cash flow; (ii) earnings contain indiscernible transient accruals; and (iii) investors use cash flow and earnings to make allocation and consumption decisions and set price. Accordingly, the quality of earnings affects production and consumption as well as price. Among other implications, the model reveals that a valuation coefficient is not just a capitalization factor; it is the product of a capitalization factor and a structural factor reflecting earnings quality and accounting bias. 相似文献

The corporate charters of a sample of Mexican firms show that private firms often significantly enhance the legal protection offered to investors, but public firms rarely do so. We construct a model that endogenizes the degree of investor protection that firms provide, using as a springboard the assumption that legal regimes differ in their ability to enforce precisely filtering contracts that provide protection only in those cases where expropriation can occur. Our model generates predictions about the types of contracts that would be employed and the levels of investor protection that would prevail across different legal regimes in both private and public firms. 相似文献

Immigration has and will continue to alter the composition of housing demand in the United Sates. In this article, we analyze results from a new survey of Mexican-heritage households to draw some inferences about tenure choice within that group. Some measures of attachment to the United States—residency status and the amount of money sent to relatives and friends in Mexico—suggest that, among Mexican immigrants, permanence is a key determinant of homeownership in the United States. More specifically, being a citizen increased the probability of ownership, whereas being undocumented reduces the probability. Surprisingly, after controlling for residency status, length of tenure in the United States does not predict tenure status, except that those who refused to report length of tenure were more likely to have higher tenure status. Those who sent remittances home to Mexico were less likely to become homeowners. 相似文献

A buyer’s technical knowledge may increase the efficiency of its supplier. Suppliers, however, frequently maintain relationships
with additional buyers. Knowledge disclosure then bears the risk of benefiting one’s own rival due to opportunistic knowledge
transmission through the common supplier. We show that in one-shot relationships no knowledge disclosure takes place because
the supplier has an incentive to transmit and, anticipating that, buyers refuse to disclose any of their knowledge. In repeated
relationships knowledge disclosure is stabilized by larger technological proximity between buyers and suppliers and destabilized
by the absolute value of the knowledge.
