This paper presents up-to-date estimates of the ability of non-resident fathers to pay child support. While no nationally representative data exist on the incomes of fathers, this issue has become more pertinent in recent years, as child support has become an important national issue. We find that fathers on average are able to pay nearly five times more in child support than they currently pay, and also that low income fathers can afford to pay substantially more than they actually pay. We also find that changes in nonmarital childbearing and the returns to education have had only minimal effects on trends in fathers' incomes.  相似文献

This article reports results of a 1993 questionnaire survey of how UK companies have been innovating technologically in response to environmental pressures. The survey sought to identify factors stimulating UK firms to innovate more environmentally friendly products and processes, and to investigate the changes in R&D activity they have undertaken to facilitate such innovation. In devising the questionnaire and interpreting the results, we have been strongly influenced by the theoretical frameworks developed over the past 15 years which describe technological developments in terms of ‘selection environments’ and ‘technological trajectories’. Useful though such frameworks are, we conclude that they need to be supplemented by concepts derived from the sociology of technology and from studies of corporate strategies.  相似文献

The pensions pillarisation agenda envisages a reduction in the role of social insurance while simultaneously advocating the parallel expansion of fully funded private sector, occupational and personal retirement contingencies. Widespread perception of looming state failure in the field of pensions delivery highlights the inherent limitations of current pension delivery arrangements. However, moves to de-emphasise the provision afforded by, predominantly, monopillar state-mandated pension systems by expanding private privision represent short-term palliative responses to deep rooted structural and demographic problems. Multipillar systems appear no more capable of guaranteeing system funding in the face of demographic ageing and structural unemployment than existing monopillar systems. Moreover, a diminished role for social insurance will leave the low paid and unemployed significantly more vulnerable in old age. Consequently, this paper argues for a pension reform agenda which, in terms of levels of income substitution, will secure an adequate social insurance element into the future.  相似文献

Land use externalities, open space preservation, and urban sprawl   总被引:4,自引:0,他引:4  
Parcel data on residential land conversion are used to investigate how land use externalities influence the rate of development and modify policies designed to manage urban growth and preserve open space. Several “smart growth” policies are found to significantly influence land conversion, including a development clustering policy that concentrates development and generates preserved open space. In addition to directly affecting a parcel's hazard rate of conversion, this policy is found to affect neighboring parcels' conversion by generating a positive open space externality that hastens their development. The implication that the clustering policy could generate a more sprawled pattern of development is explored using spatial simulation.  相似文献

This paper assesses how the Dutch system of taxation, cash transfers and non-cash benefits redistributes between the rich and the poor. The approach in this paper deviates from the usual approach by incorporating the full life cycle in the measurements, rather than only the annual effects. Moreover, the coverage is larger than is usually the case: the paper takes account of both direct and indirect taxes and direct and indirect benefits. In order to obtain the measurements on redistribution, we use the level of educational attainment to classify the population. We therefore measure, in terms of present values, the average net benefit from government policies for an average representative person of each level of education. The results indicate a sizable redistribution from the rich to the poor and a significant reduction of welfare inequality. The net effect on welfare inequality is, however, substantially smaller than when measured on an annual basis.  相似文献

In the conventional income-expenditure model with rigid wages, the aggregate supply curve is upward sloping. Increases in demand therefore imply increases in real output and employment. We demonstrate here that this conclusion depends on the form of money illusion implied by the rigid wage assumption. If we assume instead that labor supply is more sensitive to price increases than to wage increases, the aggregate supply curve is negatively sloped, and the conventional policy multipliers are thereby reversed. In the second section, we show that this result also follows if labor supply depends on the expected real wage.  相似文献

This paper analyzes the effects of trade liberalization of tariff‐rate quotas under import “state trading enterprises” (STEs) in agriculture. An analytical framework is provided to determine the importance of which instrument is binding under competition (the in‐quota or out‐of‐quota tariff or the quota) and under the initial STE equilibrium. It also depends on whether or not the STE controls both the domestic market prices and owns/controls the import quota (and whether it is obligated to fill the quota or not). An empirical example of the rice STE in South Korea has simulations showing that an increase in imports can be achieved through a moderate expansion of the quota or a decrease in the out‐of‐quota tariff to the level where it becomes binding. However, a significant level of quota expansion induces the STE to switch to the autarky solution and social welfare declines.  相似文献
