The use of time for child care and housework among Swedish families is investigated. We allow the effect of children on child care and housework to vary by age of the child and also by whether the child is cared for outside the home or not. Our estimates allow us to compute the total cost of children in the form of the cost of time, and the cost of goods, services and housing.The result shows that time used for child care decreases sharply with the age of the child but this is not the case for time used for other housework. Considerable economies of scale is found to prevail for time used for child care. Child care outside the home reduces time use for other housework but the effect on time used for child care is quite small. For the average family time use cost make up more than half of total child cost. Our estimates indicate that decreased time use cost for children caused by care outside the home are not very different from a typical parental fee for public day care.This research was supported by a grant from the Swedish Council of Social Research (SFR). We thank Lennart Flood for useful comments on an earlier version.  相似文献

The April 1993 CPS differs from the March 1993 CPS in a number of respects. The April 1993 CPS supplement surveys only workers, whereas the March CPS examines the noncash benefits received by all Americans. The April CPS asks workers about health coverage in the week in which the questions were fielded, whereas the March CPS asks about coverage in the preceding year. In April 1993, there were 112.5 million civilian American workers between the ages of 18 and 64 with jobs. Eighty-two million (73 percent) of them worked for an employer that sponsored a health insurance plan, and 65 million (58 percent of all workers) participated in their employer's health plan. About one-third of workers at firms with fewer than 10 employees had employers who offer health benefits; about one-quarter of all of the workers in these firms participated in their employer's plan. Conversely, 94 percent of workers at firms with more than 1,000 employees had an employer who sponsored health benefits, and over 77 percent of these workers participated in their employer's plan. There are 16.5 million American workers whose employers sponsored health benefits but who did not participate in these benefits. Over one-half of these workers (8.5 million) chose not to be covered. Another 36 percent of these workers (5.9 million) did not participate because they were ineligible or denied coverage. Over 66 percent of the ineligible workers did not participate because they were part-time, contract, or temporary workers. Another 26 percent had not yet completed a probationary period. Among the reasons that those who chose not to participate in their employer's coverage, the vast majority (75 percent) stated they were covered by another health care plan. Twenty-nine percent stated that they chose not to purchase coverage because it was too costly or that they did not need or want the coverage. In 1993, there were 16.7 million workers with no health insurance coverage. The vast majority of these workers (95 percent) were employed by private employers. Sixty-six percent of the workers with no health insurance coverage were self-employed or worked for firms with fewer than 100 employees.  相似文献

A survey was mailed to 100 physician executives identified through the 1991 American College of Physicians Executives directory. The subjects were asked to rate 17 managerial areas on their value to the subjects' current work, on the subjects' preparation in the areas, and on the need for training in the areas. In addition, the subjects were asked how best to accomplish training in the areas and for a list of areas of greatest importance in the future for physician executives. The subjects rated communication skills, quality assurance, utilization review, and personnel management as being of primary value in their current roles. Preparation was most adequate in communication skills and most inadequate in the areas of finance and organizational management. Training was deemed desirable in all areas, but was thought to be most necessary in communication skills, negotiations, strategic planning, and organizational management. There was least desire for training in the areas of labor law and employment law. The most popular means of training were doing a fellowship in administrative medicine, receiving continuing education through seminars or workshops, or getting a degree in management.  相似文献

Recently, the number of physicians who have been interested in alternative careers has vastly increased. Many physicians express dissatisfaction with clinical practice, but they are uncertain about which nonclinical options are appropriate for them. Pursuing a different career after many years of studying and practicing medicine can seem like an overwhelming task. In this article, the author briefly outlines a decision-making process that can be used in analyzing career options and suggests some careers that have provided challenging opportunities for physicians.  相似文献

"Teacher, what are we going to do next class?" This is an exciting question which I often hear from my students. As an English conversation teacher, I can make the learning of English either a dull and boring duty, or an exciting adventure. It is very important that I make my students hate missing my class, and keep them guessing just what will happen the next time! Let us consider some important ways that any teacher can help his other students want to do their  相似文献
