This paper uses a unique policy change in Ontario, Canada, to provide direct evidence on how reducing the length of high school would impact student performance in university. After a five‐year educational program was eliminated from Ontario high schools and replaced with a four‐year program, two graduating cohorts with different amounts of high school education simultaneously entered university. The results demonstrate that students who receive one less year of high school education perform significantly worse than their counterparts in all subjects, even after the age difference between the cohorts is accounted for.  相似文献

The organic dairy category is one of the fastest growing categories of organic foods in the US. Organic milk consumers generally cite perceived health benefits and lower risk of food contamination, as well as perceived superior quality and environmental sustainability of organic farming methods, as the major motivations for preference of organic over conventional milk. While the attributes of organic milk that are valued by consumers are fairly well-known, more ambiguity exists regarding the demographic characteristics of the typical organic milk consumer. This research makes use of experimental data from 148 adult participants and use a Classification and Regression Tree (CART) analysis, a nonparametric modelling approach, to identify how Willingness-to-Pay (WTP) for organic milk varies with the demographic profile of experiment participants. The study finds that perceived taste of organic milk, concern for the risk of consuming conventional milk, being a primary shopper, and the quantity of milk consumed are the major factors that separate experiment participants into groups with high and low WTP for organic milk.  相似文献

The authors report on the design and implementation of a pilot program to extend the principles of intensive writing outlined by W. Lee Hansen (1998), Murray S. Simpson and Shireen E. Carroll (1999) and David Carless (2006) to large macroeconomics classes. The key aspect of this program was its collaborative nature, with staff from two specialist units joining forces with two economics instructors to provide students with significant resources and direction in a short program of writing, embedded within an intermediate macroeconomics subject at the University of Technology, Sydney (UTS). The objective was to test potential strategies and to identify points of improvement for a more intensive program of writing development at the next stage of implementation. The authors review the literature on student writing and associated assessment issues, outline the central design features of the UTS program, and take a closer look at the centerpiece of a strategy for overcoming writing problems: a series of writing workshops targeted at two related assignments within the intermediate macroeconomics course.  相似文献

The objectives of this study of household grain consumption in China are to update previous estimates of consumption parameters, to look at the effect of urbanization on grain consumption and to compare household demand patterns across the region. Household grain consumption is divided into two categories: direct and indirect grain consumption. Demand systems are estimated for four consumer groups, rural, town, city and large city, respectively, using data from the 1991 rural and urban household surveys undertaken by China's State Statistical Bureau. The impact on grain consumption of income, price and urbanization is particularly elaborated.  相似文献
