ABSTRACTThis article examines the extent to which trade costs influence the magnitude and direction of both east-west and north-south trade in Canada and the United States. With the aid of an alternative framework which pays attention to key estimation issues in the gravity literature, we garner further evidence in support of a decline, over time, in the home bias syndrome. Our results uphold the Linder hypothesis but refute the Heckscher-Ohlin factor endowment proposition. In light of the recently modernized trilateral trade agreement in North America, we conclude with policy lessons on buffering the Canadian economy from asymmetric trade shocks from its southern neighbor. 相似文献

This article describes a new pedagogical tool, text‐to‐video animation software, that accounting instructors can adopt to easily generate quality videos that address a variety of accounting learning objectives. Although this tool can be used to enhance traditional pedagogical methods, such as case analysis and discussion, it can also be used to address accounting learning objectives not currently addressed by traditional pedagogical methods. This article outlines the benefits of adopting and using this tool in financial and managerial accounting courses, and encourages further study of its effectiveness. 相似文献

When writing a case analysis, most students first allocate time to plan the content and structure of their response, and then proceed to write with differing degrees of urgency, the outcomes of which are case responses of differing quality. This study examines the extent to which planning time influences writing urgency and, ultimately, the quality of case responses in a time‐constrained setting. It also investigates whether these behaviors and outcomes depend on students’ frame of mind, by experimentally inducing differing types of pre‐examination self‐talk. Analyses show that planning time was negatively associated with writing urgency; students who spent more time planning subsequently wrote with less urgency. Writing urgency was positively associated with case response quality and, after controlling for differences in writing urgency, planning time was positively associated with response quality. Results indicate that different planning and writing behaviors can be induced by different forms of self‐talk prior to the writing task. Relative to interrogative self‐talk (“Will I …?”), exclamatory self‐talk (“I will …!”) caused higher‐achieving students to spend more time planning, but then write with less urgency and subsequently produce lower‐quality case responses. Conversely, after engaging in exclamatory rather than interrogative self‐talk, lower‐achieving students spent less time planning but then wrote with greater urgency and produced higher‐quality responses. These results indicate that (i) planning significantly affects writing and performance, (ii) students can influence their own planning behavior through pre‐task self‐talk, but (iii) pre‐task self‐talk can be beneficial or detrimental depending on students’ prior achievement. 相似文献

This paper refutes the proposition by Caplan and Gochenour that there is no such thing as natural resources because all goods are produced. Caplan and Gochenour use that proposition to argue against the reform proposal of Henry George and his followers, to replace all taxes with a single tax on land value. The rebuttal to Caplan and Gochenour made by this paper is that the discovery of a resource does not constitute its production. The refutation here argues that entrepreneurship and investment create human capital and capital goods, not natural resources. Discovery is not the same as invention or production. 相似文献

Adequate flow of appropriate information to farmers is vital for accelerating the uptake of modern agricultural technologies and improving access to markets, all of which are important for the transformation of African economies. Yet there is limited evidence regarding how information should be disseminated to farmers to achieve the needed impact. Should ICT-based approaches be used together with traditional methods, or should they be used alone? We used cluster quasi-random and randomized experiments involving 140 villages in southern Mali to study three chains of causality: does farmer training increase knowledge? Does knowledge lead to change in behavior? Do the different actions generate varying economic outcomes? We show that the role of farmer training in the uptake of extension advice may be overstated in some settings; that procrastination and inattention are more binding constraints to recommendation adherence than information per se; and that such constraints could be mitigated by timely voice SMS reminders. Although timely reminders nudged farmers to take-up recommendations, leading to meaningful improvements in some intermediate outcomes, these impacts were not large enough to generate improvements in output, prices and profits in the short term. These findings must be interpreted within the context of imperfect compliance with experimental protocols, which pose threats to both the internal and external validity of some of the impact estimates. 相似文献

Metrics addressing process safety incident performance typically focus on frequency and severity statistics. Often, these lagging metrics are not overly sensitive to actual performance, making trending and forecasting difficult. This article presents the results from a statistical study of a large incident dataset where changes in the Pareto shape parameter were observed as a function of time. This approach has been found to give far better insight into process safety performance than traditional incident metrics and readily relates back to concepts such as the “incident triangle” and “layers of protection.” Through the application of this approach, trends within process safety incident performance have been observed earlier, and more accurate forecasting has allowed for the identification of anomalies. In turn, these critical observations have allowed for the better structuring and targeting of process safety programs. Although incident data are generally considered as a lagging indicator, this approach has clearly reduced the lag time associated with this type of data and has given valuable insight into the current status of process safety performance. © 2009 American Institute of Chemical Engineers Process Saf Prog 2009 相似文献
