Using local variation between municipalities, I analyze the degree to which the price of high‐quality publicly subsidized childcare affects female employment following maternity leave. Importantly, prices are income dependent and thus likely endogenous, yet by exploiting information on minimum income compensation during non‐employment, I bypass this problem. The results show that the price negatively affects employment. A price increase of €1 per month decreases employment by 0.08%, which corresponds to a price elasticity of −0.17. These effects prevail during the first 12 months after childbirth. I also find that availability of childcare increases employment.  相似文献

The conventional wisdom has been that men outperform otherwise equivalent women in collegiate economics courses. Recent work in science, technology, engineering, and mathematics (STEM) fields documenting gains by women suggests that it is time to reevaluate the gender performance gap in economics. Surveying 68 studies containing 235 distinct regressions published since 1980, we find that 68.4% of regressions report men outperform women, though this is only statistically significant in 30.7% of regressions. Although the literature points to numerous reasons for this gap, our focus is on the effects of study design and the impact of broad socio-cultural changes over time. Using meta-regression analysis, we find that the likelihood of observing a statistically significant gap has declined noticeably, by almost 3% annually. Although the drop may not be as large as in some STEM fields, the result is highly robust to the specification of the time trend and the model.  相似文献

I have recently been thinking of how to be “virtuous” as I engage in doing qualitative research for social justice. In this essay, I explore the complexities and risks involved in representing the researcher-self amidst competing (and perhaps false) dichotomies of the personal/professional life and the scholar/activist. To do so, I deconstruct places in my scholarship where I was willing (consciously and unconsciously) to take risks, where I took risks but was socialized to conform, where I am still unwilling to take the risk and where I am currently writing the risky. The goal is to create a dialogue about the perplexities that surround representing the “researcher self” with goals for social justice.  相似文献

Interviews were conducted in Kitchener‐Waterloo, Ontario, at eight different recreation areas. These were classified as either designated or nondesignated recreation areas. The interview was designed to obtain information regarding demographic characteristics of the user, attitudes toward the use of urban recreation areas (both playgrounds and areas that are not designated as recreational in character), reasons for choosing a particular recreation site and what users considered to be part of an ideal recreation area. Information gathered by the interview method was supplemented by a series of observations. Results indicated a significant difference between age and reasons for nonattendance at designated play areas. Differences in use by sex were, however, not significant.  相似文献

The purpose of this article is to identify the extent of inward and outward foreign direct investment (FDI) worldwide. A large number of countries were aggregated on a regional basis to examine their inward and outward stocks as a percentage of gross fixed capital formation for the period 1980–2006. Among the findings was that the annual increase for both inward and outward FDI was less than 1%. Also, countries grouped by the aggregates developed, Africa, Latin America and Caribbean, Asia and Oceania, and developing were found to differ significantly in their means.  相似文献

This study investigated the meanings attached to leisure by low-income young consumers. In order to achieve this research objective, the study was conducted in a low-income community in the city of Rio de Janeiro. We used semi-structured interviews with community leaders and observation to acquire a preliminary knowledge of the field. We then interviewed 80 young people with ages varying from 15 to 25?years old. The data were treated qualitatively and quantitatively, using cluster analysis. The results showed, as expected, that these consumers have limited resources for leisure activities, due to lack of money, time or both. However, although the subjects recognise leisure as an important part of their lives, they attribute different meanings to it. Also, their understanding of free time and leisure varies somewhat. The findings provide evidence that these consumers' view of leisure, to some extent, resembles a pre-industrial understanding of leisure, associated with time for rest and time with family and friends. The results also permitted the identification of four different clusters, based on the meanings attributed to leisure and free time, individual aspirations and demographic characteristics.  相似文献

Little is known about how various strategic orientation dimensions determine market orientation. The authors identify four key dimensions of a firm's strategic orientation as critical antecedents to market orientation: the firm's aggressiveness, its future orientation, the extent of marketing formalization, and risk proclivity. Moderating effects of two environmental forces, competitive intensity and technology turbulence, are also considered in light of their relationship with various dimensions of strategic orientation and market orientation. Using a survey with firms spanning multiple industries, the proposed effects are tested with latent class analysis with multiple regimes. The results, based on an optimal two-regime solution, show that that although market orientation is significantly impacted by these strategic orientation dimensions, the pattern of influence differs based on a firm's membership in one of two regimes.  相似文献

This paper describes and develops a model for calculating location-based strategic values of foreclosed properties considered for acquisition and redevelopment by community development corporations (CDCs). A property’s strategic value refers to its proximity to site-specific neighborhood amenities and disamenities (e.g. schools, public transit, distressed properties), given the relative importance of that proximity to CDC organizational and community objectives. We operationalize the concept of strategic value, and apply this concept to a salient public sector decision problem. Using data and value assessments from a CDC engaged in foreclosed housing redevelopment, we compute measures of strategic value for a set of acquisition candidates. We show that strategic values can differ in systematic ways depending on the types of amenities and disamenities identified as relevant for CDC acquisition decisions, the relative importance assigned to those amenities and disamenities, and the utility maximization objectives of the CDC. We conclude by proposing a multi-criteria decision model for foreclosed housing acquisition and redevelopment which incorporates a theory of residential housing impacts for which strategic value measures are a special case.  相似文献
