On Hoover’s Scale-Free Forecast Accuracy Metric MAD/MEAN

Asia-Pacific Financial Markets - In this study, we find that Hoover’s scale-free forecast accuracy metric MAD/MEAN is only recommended when the coefficient of variation (c.v.) is small. Using...

区域中心城市创新生态圈要素架构、生态特征与运行机制

区域中心城市创新生态圈以生物学为隐喻，注重发挥创新主体的能动作用，能够放大区域中心城市发展优势。在回顾创新生态圈理论渊源的基础上，界定区域中心城市创新生态圈内涵，明确创新生态圈要素构成；以企业聚集发展为逻辑起点，探讨区域中心城市创新生态圈生态特征；基于生态学、创新理论等跨学科知识，构建区域中心城市创新生态圈演进模型，探究其运行机制。研究认为，区域中心城市创新生态圈具有开放式协同、动态自调节、多样性共生、自组织演化等生态特征，其运行机制由协同共生机制、风险识别与防控机制、利益分配机制和环境匹配机制共同组成。     

Accuracy of self-reports on donations to charitable organizations

In this paper we assess overall accuracy in survey self-reports on giving to charitable organizations, direction of bias in self-reports, and the influence of this bias on relationships. We compare donations to one specific health charity reported in the Giving in the Netherlands Panel Study 2003 with donations recorded in the database (n =  191). We find that (a) reported donations are significantly higher than recorded donations; (b) reported amounts contributed are correlated very strongly with recorded contributions; (c) differences between amounts reported and amounts recorded are positively related to education, religious affiliation, and the tendency to social desirability, and negatively to household income. This suggests that effects of education are overestimated and effects of income and religious affiliation are underestimated using self-reports on donations rather than archival records.     

集装箱信息的条码化研究

现代集装箱码头很多作业已经实现了自动化或半自动化,但码头理货和闸口工作人员仍要用无线手提终端机人工输入集装箱信息。本文研究了使用条码技术(39条码和PDF417码)对集装箱信息进行编码。运用了文本压缩技术,将包含集装箱信息的PDF417码压缩为5行二维条码。通过将集装箱信息的条码化,并借助市场上已有的无线条码数据采集器扫描条码,可以实现码头理货和闸口工作人员录入数据的自动化,降低工作强度,提高生产效率。

Shortfall aversion

Shortfall aversion reflects the higher utility loss of spending cuts from a reference than the utility gain from similar spending increases. Inspired by Prospect Theory's loss aversion and the peak‐end rule, this paper posits a model of utility from spending scaled by past peak spending. In contrast to traditional models, which call for spending rates proportional to wealth, the optimal policy in this model implies a constant spending rate equal to the historical peak when wealth is relatively large. The spending rate increases when wealth reaches a model‐determined multiple of peak spending. In 1926–2015, shortfall‐averse spending is smooth and typically increasing.     

Who should sell stocks?

Never selling stocks is optimal for investors with a long horizon and a realistic range of preference and market parameters, if relative risk aversion, investment opportunities, proportional transaction costs, and dividend yields are constant. Such investors should buy stocks when their portfolio weight is too low and otherwise hold them, letting dividends rebalance to cash over time rather than selling. With capital gains taxes, this policy outperforms both static buy‐and‐hold and dynamic rebalancing strategies that account for transaction costs. Selling stocks becomes optimal if either their target weight is low or intermediate consumption is substantial.     

Comparative Urbanism and the ‘Asian City': Implications for Research and Theory

While voices in the comparative urbanism literature call for researchers to approach comparison with more experimental and critical methodologies, there remains no consensus on how to design and realize these studies. This essay examines the implications of comparative urbanism for researching the ‘Asian City'. Given the critique of existing modes of comparison embedded in recent calls for a new comparative urbanism, researchers are faced with a number of pressing questions: How do we approach this ‘regional' topic in a way that both resists categorizing the ‘Asian City' as an exotic ‘other', elevating it onto a mythical pedestal, yet appreciates its differences, localisms and unique ‘cosmopolitan vernacular' (Clifford, 1997; Werbner and Modood, 1997)? This essay thus highlights the multiple challenges of applying the comparative lens to the ‘Asian City', arguing that broader conceptualizations of the ‘Asian City' help to address the dangers in isolating Asian research into its own canon of parochial urban theory and offering a greater diversity of possibilities for justifying case selection in comparative approaches. In doing so, we hope that this essay responds to the comparative turn by illuminating to some extent its inherent complexity and methodological challenges.
