This study deals with educational production in Austria and is focused on the impact of schoolmates on students’ academic outcomes. We use PISA 2000 and 2003 data to estimate peer effects for 15 and 16 year old students. School fixed effects are employed to address the potential self-selection of students into schools and peer groups. The estimations show significant positive effects of the peer group on students’ reading achievement, and less so for mathematics. The peer effect in reading is larger for students from less favorable social backgrounds. Furthermore, quantile regressions suggest peer effects in reading to be asymmetric in favor of low-ability students, meaning that students with lower skills benefit more from being exposed to clever peers, whereas those with higher skills do not seem to be affected much.  相似文献

In recent decades, the differences between the education and training systems in the liberal and coordinated market economies have increased. It is not possible to understand such different developments by focusing exclusively on the internal dynamics of vocational and general education systems. Vocational education and training (VET), and particularly apprenticeship systems rather than school‐based VET, are deeply embedded in the different national production, labour market, industrial relations and status systems. In order to contribute to a better understanding of the dynamics of VET, we examine recent developments in general and vocational training and its links to the labour and product market in five contrasting countries, namely, Denmark, Canada, Germany, Korea and the USA. In particular, differences in industrial relations, welfare states, income distribution and product markets are the main reason for the persistent high level of diversity in vocational training systems. The difference can perhaps be summarized as follows: in the coordinated market economies, the modernisation of vocational training is seen as a contribution to innovation in the economy, while in liberal market economies, it is seen as a siding into which weaker pupils can conveniently be shunted.  相似文献

While many company managers and academic researchers have argued that businesses that develop a sustainability focus also may improve their financial performance, little information is known about whether firms' different types of sustainability activities are related to varying degrees of financial gain. This paper assesses the economic relationship between two types of sustainability activities – lower‐ and higher‐order – derived from the sustainability value framework of Hart and Milstein (2003). Our analysis reveals that both types of sustainability activities are similarly associated with firms' financial performance in terms of direction and trend. However, the average level of financial benefits related to firms' higher‐order sustainability activities (which develop new products and processes) is greater than the average level of financial benefits related to firms' lower‐order sustainability activities (which modify existing products and processes). These findings offer initial evidence that companies that reach further by developing higher‐order sustainability activities may reap greater financial benefits, while improving the natural environment to a greater degree.

While the role and importance of marketing have grown in nonprofit organizations, marketing knowledge in nonprofit education organizations, specifically primary schools, is sparse. This paper reports the research findings of an exploratory study designed to examine the transfer of marketing knowledge to Catholic primary schools. It identifies and explores what school leaders know about marketing, how they acquire that knowledge, and what factors contribute to or impede its development. Qualitative data gathered from Catholic school educational leaders reveal that while marketing is viewed in schools as an important management function, marketing knowledge is slow to transfer. Findings reveal that marketing knowledge is primarily developed unintentionally, as a result of trial and error, and that a lack of formal marketing training results in a heavy dependence on volunteers. Findings also indicate that school leaders have minimal autonomy under the Diocese, which, along with economic, cultural, and structural barriers, functions to limit marketing knowledge development. It was also found that, although cross‐sector cooperation is desired among educational leaders, it is not pursued, further limiting the transfer of marketing knowledge. Theoretical and managerial implications for resource‐strapped primary schools in competitive environments are discussed.  相似文献

We use a large and rich administrative household panel data set to estimate labour supply responses for a large number of subgroups in the Netherlands. The identification of the parameters benefits from a major tax reform in the data period. We uncover large differences in behavioural responses. In particular, we find differences in labour supply responses between households with and without children that are much bigger than suggested by previous studies that had to pool these household types in the estimation of preferences. An efficient tax‐benefit system should take the substantial heterogeneity in behavioural responses into account.  相似文献

Staple food prices in cities in eastern and southern Africa rose sharply between late 2007 and early 2009, leading to estimates of massive increases in food insecurity and hunger. However, in assessing the impacts of soaring food prices on urban consumers’ access to food it is important to consider food price changes relative to changes in per capita incomes. In this study, we use the case studies of Zambia and Kenya, where data are available on food prices, wage rates, incomes, and other indicators of urban purchasing power to answer two main questions: (i) how did staple food purchasing power at the height of the food price crisis compare to levels over the last 15 years? and (ii) did the food price crisis exacerbate an already declining trend in staple food purchasing power, or did it reverse a trend of stable or improving staple food affordability? Results indicate that staple food purchasing power in urban Zambia and Kenya improved markedly in the 10–12 years prior to the food price crisis. Most measures of bread and maize meal affordability at the start of the crisis in 2007 were at levels 1.0–4.3 times higher than in the mid-1990s. These gains for urban consumers were slashed but not completely reversed during the food crisis. Between 2007 and 2009, maize meal and bread were still more affordable in urban Zambia than all periods between 1994 and 2003. In urban Kenya, staple food purchasing power as of 2008/2009 was comparable to levels in 2000/2001–2004/2005 according to some indicators, while other measures suggest that the food price crisis reduced staple food purchasing power to levels lower than any other year in the period 1994/1995–2007/2008.  相似文献

Alternative approaches to discrete working time choice in an AGE framework   总被引:1,自引:0,他引:1  
We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly incorporates a logit discrete-choice approach into an AGE framework. On the grounds of both calibration consistency and adequate accommodation of within-household interaction, we argue that the logit approach is preferable.  相似文献

Given the large investments required for high-quality complaint handling design, managers need practical guidance in understanding its actual importance for their particular company. However, while prior research emphasizes the general relevance of complaint handling design, it fails to provide a more differentiated perspective on this interesting issue. This study, which is based on an integrative multi-level framework and a dyadic dataset, addresses this important gap in research. Results indicate that the impact of a company’s complaint handling design varies significantly depending on the characteristics of the complaining customers with which the firm has to deal. Further, this paper shows that, contingent on these characteristics, a company’s complaint handling design can shape complainants’ fairness perceptions either considerably or only slightly. Overall, findings suggest that companies should apply an adaptive approach to complaint handling to avoid misallocation of attention, energy, and resources.  相似文献

This paper pertains to the application of knowledge engineering methods to aeronautical search and rescue in Canada. We modelled at the knowledge level the reasoning process of a search mission coordinator when conducting a diagnosis task to determine the routes likely followed by an aircraft missing overland. Knowledge engineering allowed us to develop a reasoning model based on documents and on interviews with domain experts. Our study was conducted in the CommonKADS knowledge modelling framework. The proposed model was validated by domain experts and implemented in a rule‐based prototype. Copyright © 2007 ASAC. Published by John Wiley & Sons, Ltd.  相似文献
