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

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

原载:http://www.nber.org/papers/w10582一、引言反倾销条款作为美国贸易法的一个组成部分虽然已有80多年的历史,但只是在近20年间才格外引人注目。在美国的贸易政策中,反倾销在过去一直不引人注意,实际上,直到Finger,Hall和Nelso(1982)写出了开拓性的论文之后,才有这方面的经济研究。从此,对反倾销政策的研究几乎全都集中在1980年以来的这段时间里。因此,我们对1980年以前的反倾销法规的运用知之甚少,对逐渐转向更频繁地运用反倾销补救措施的程度亦知之甚少。本文旨在用历史的观点研究美国近来的反倾销,特别关注二战以来这段时间。这一… 相似文献

The development of optimal human resource practices is often contingent on the accurate statistical testing of potential interventions. Testing the efficacy of HR interventions can be enhanced by taking additional measures to improve statistical power, but the traditional means of increasing power through sample size are often beyond the cost and ability of HR professionals to pursue. This article, therefore, focuses on measurement procedures as an alternative way to increase statistical power for detecting HR intervention effects. Selection of reliable and appropriate measures and subsequent instrumentation are examined as efficacious and cost‐beneficial techniques that can be employed during the planning and designing stage of a study for augmenting statistical power to optimize business decision making. © 2012 Wiley Periodicals, Inc. 相似文献

The marked increase in the availability of spatial data has forced researchers engaged in land use modeling to directly confront
the question of space and the theoretical and methodological challenges involved in developing spatial models. Advances have
come from multiple disciplines, most notably through the development and application of spatial theory and methods from regional
science, geography, urban economics and more recently, theoretical and applied econometrics. The main goal of this paper is
to summarize the econometric challenges of spatial data and to highlight spatial models and methods with a particular focus
on models of land markets and land use change. We also discuss the data and modeling challenges associated with modeling the
underlying spatial economic mechanisms that give rise to land use patterns and the complexities involved in modeling land
use as a coupled economic-ecological system. 相似文献
