Designer path independent choice functions

Summary. This paper provides an algorithm for the construction of all PICFs on a finite set of alternatives, V, designed by an a priori given set I of initial choices as well as the determination of whether the initial set I is consistent with path independence. The algorithm is based on a new characterization result for path independent choice functions (PICF) on finite domains and uses that characterization as the basis of the algorithm. The characterization result identifies two properties of a partition of the Boolean algebra as necessary and sufficient for a choice function C to be a PICF: (i): For every subset A of V the set is an interval in the Boolean algebra 2 ^V . (ii): If A/B is an interval in the Boolean algebra such that C(A) = C(B) and if M/N is an upper transpose of A/B then C(M) = C(N). The algorithm proceeds by expanding on the implications of these two properties.Received: 5 November 2003, Revised: 20 July 2004, JEL Classification Numbers: D00, D70.

South African financial reporting students' reading comprehension of the IASB Conceptual Framework

Students studying principles-based IFRS require a thorough knowledge and understanding of the IASB's Conceptual Framework (Framework). Reading comprehension of the Framework enables students to access and decode its content. This allows the development of the ability to analyze, critique, evaluate and synthesize the content. The objective of this study was to evaluate students' reading comprehension of the Framework using the Cloze procedure. Researchers have questioned whether there should be different assessments of reading comprehension for different demographic groups. This paper explores differences in the reading comprehension of a diverse cohort of South African financial reporting students. Many students demonstrated reading comprehension at the Independent or Instructional Level. Further analysis revealed statistically significant differences between reading comprehension by language of instruction and the attendance, or not, of prior reading courses. While this study considers South African students, the results may be of interest to instructors in other multiracial or multilingual environments.     

我国食品行业事后监管失灵的博弈分析

近年来,我国食品安全问题层出不穷,愈演愈烈,通过构建食品生产厂商与监管者之间的完全信息动态博弈模型,计算出子博弈精炼纳什均衡解,即厂商选择过度造假,监管者事后过度监管。结论与我国食品行业事后监管模式的现实后果高度吻合,具有很强的解释力,并且将其与帕累托最优解相比较,说明了次优均衡产生的原因。

上海1978—2009年能源反弹效应的完全分解分析

文章运用完全分解模型对经济增长中的能源反弹效应进行分解分析,并运用上海1978-2009年间的数据进行实证研究。结果表明：无论是技术效应还是结构效应,影响能源消费量增长的主要因素是规模效应,并且其作用远远大于能源效率提高所带来的能源消费量减少的影响,这使得经济增长中出现了能源效率提高而能源消费量反而持续上升的反弹现象。要弱化甚至消除反弹效应,一方面要进一步优化产业结构,但更为重要的是进行总量控制。
