Data from the March 1991Current Population Survey [Bureau of the Census, 1992] were used to investigate the effects of children on single and married mothers' labor force
participation decisions. Logit results indicated that for both single and married mothers, an increase in education and market
experience increases the probability of market participation while an increase in income has a negative effect on the likelihood
of mothers' labor market participation. The number of children present in the household negatively affected participation
while an increase in the age of children positively influenced the mother's labor market participation. The spacing effect
in the married group and the timing effect in the single group were significant. Furthermore, an increase in the number of
older children in the household (between the ages of 12 and 17 years) increased the probability of labor market participation
by single mothers but decreased that of married mothers. 相似文献

ADRs,Analysts, and Accuracy: Does Cross Listing in the United States Improve a Firm's Information Environment and Increase Market Value? 总被引:10,自引:0,他引:10
This paper investigates the relation between cross listing in the United States and the information environment of non‐U.S. firms. We find that firms that cross list on U.S. exchanges have greater analyst coverage and increased forecast accuracy than firms that are not cross listed. A time‐series analysis shows that a change in analyst coverage and forecast accuracy occurs around cross listing. We also document that firms that have more analyst coverage and higher forecast accuracy have higher valuations. Furthermore, the change in firm value around cross listing is correlated with changes in analyst following and forecast accuracy, suggesting that cross listing enhances firm value through its effect on the firm's information environment. Our findings support the hypothesis that cross‐listed firms have better information environments, which are associated with higher market valuations. 相似文献

This article uses Bayesian vector autoregressive models to examine the usefulness of leading indicators in predicting U.S. home sales. The benchmark Bayesian model includes home sales, price of homes, mortgage rate, real personal disposable income, and unemployment rate. We evaluate the forecasting performance of six alternative leading indicators by adding each, in turn, to the benchmark model. Out-of-sample forecast performance over three periods shows that the model that includes building permits authorized consistently produces the most accurate forecasts. Thus, the intention to build in the future provides good information with which to predict U.S. home sales. Another finding suggests that leading indicators with longer leads outperform the short-leading indicators. 相似文献

Air transportation is a key strategic asset in that it provides access to markets and thereby enables the economic development of nations. Thus, in order to maintain their competitiveness in a global economy, countries must invest in air transportation infrastructure to ensure their ability to meet current and future demand for aviation services. The objective of this paper is to develop and illustrate a methodology for evaluating the strategic value of air transportation infrastructure, in particular the benefits associated with the ability to react quickly to changes in the market. The hypothesis is that by recognizing and taking advantage of this strategic value, it may be possible to design better policies for aviation infrastructure delivery.The methodology developed here uses system dynamics to model different strategies for infrastructure delivery. These strategies are defined by three variables: the amount of capacity increase, the time to deliver the capacity and the congestion threshold that triggers the need for capacity delivery. Monte Carlo simulation is used to take into account multiple sources of uncertainty. The model shows that a strategy of capacity delivery based on small increments and short response times can yield more benefits than strategies that consider large capacity increases and long response times. Furthermore, in the specific airport example considered here, it was found that a congestion threshold of 75% should be the trigger for capacity enlargements if strategies based on small capacity increments and 1 or 5 years to increase capacity are considered. The lesson for decision-makers is that congestion delays must be addressed with foresight. 相似文献

This article explains the origins of s.4 of the Employment Act 1980 and assesses the place of this provision in the corpus of labour legislation enacted by the Conservative government since 1980. Its principal aim is to concentrate upon the concept of reasonableness which is central to the operation of the provision and to evaluate critically the role of the EAT and the industrial tribunals in interpreting it. Finally, the article seeks to assess the impact of the tribunaľs interpretation of s.4 on union admission and expulsion procedures. 相似文献

With charities of all sizes now having the ability to collect and store very large quantities of data about their donors on in‐house database systems, detailed donor performance analyses have an increasingly essential role to play in the effective planning and management of fundraising. If, however, such activities are to support fully the work of fundraisers then it is important that they are undertaken from the perspective of the fundraiser rather than of the specialist data analyst. This paper introduces an approach to donor performance analysis that is founded on what is termed a ‘donor lifecycle model’. The aim of this is to provide a formal analysis methodology that provides end results that can be more easily interpreted by nonspecialists and so more effectively used in support of the efficient planning of fundraising programmes.

Organizations require guidance on the most effective functional areas in which to invest in order to improve and sustain environmental performance. As managerial practices progress from concerns with compliance towards practices seeking competitive advantage, more theory is needed regarding the manner in which corporate strategy and operational practices influence environmental performance. This research considers the potential for previously under‐researched complementarities between strategy and operations and the bridging role of environmentally specific practices such as the use of environmental experts as determinants of environmental performance. Using a sample of manufacturing firms, this study explores the relative contribution to environmental performance of strategic intentions, core operational practices such as data and quality management and environmentally specific practices that link strategy to operations. The most significant influence on environmental performance was found to be environmental expertise – which creates a bridge between strategy and operations – and information‐intensive practices such as quality and data management. Strategic intentions or core operational practices in isolation were not considered sufficient support to successfully maintain or improve environmental performance. This research provides a contribution to our understanding of interactions between those functions that have the greatest influence on environmental performance management in manufacturing firms.
