A GIS-based toolkit for route choice analysis

This paper develops and applies the route choice analysis (RCA) toolkit. This GIS-based toolkit generates a suite of over 40 variables describing route characteristics such as distance, travel time, speed statistics, number of intersections, number of turns, number of stop signs/stop lights, and a measure of route circuity, to name a few. The input to the toolkit is one or more routes, which can be obtained from global positioning system (GPS) data or some other means (e.g., shortest path). While the toolkit is designed to support route choice modeling by generating variables that have been tested in previous modeling efforts, we demonstrate its utility by testing the hypothesis that workers choose routes to minimize either travel time or distance between home and work. A GPS-enhanced data set of 237 observed routes for home-to-work trips collected for auto drivers in Halifax, Nova Scotia, Canada is used in our analysis. We find that the null hypothesis is refuted - that is, a comparison of observed routes to their shortest-path alternatives based on time and distance via inferential statistics indicates that observed routes are significantly longer compared to their alternatives. This finding suggests that workers may choose routes based on other route attributes. The attributes generated by the RCA toolkit for observed, shortest time, and shortest distance routes are compared and significant differences are noted.     

Colliding Interests – Age as an Automobile Insurance Rating Variable: Equitable Rate-Making or Unfair Discrimination?

Many private business relationships are increasingly characterized by claims that certain actions should not be permitted since particular right claims are involved. Such claims should be taken seriously, but are they always ethically legitimate? This paper analyzes one context, the use of age as a rating variable in the pricing of automobile insurance, where such claims are made. By identifying, evaluating and assessing the relevant basis for the differentiation, actuarial equity, it is concluded that there is an ethical basis for such a practice. The analysis also provides an equivalent means for considering other such analogous claims where actuarial equity is involved.     

An Empirical Investigation of the Effect of CFO Power on Disclosure Quality

We examine the association between chief financial officer (CFO) power and disclosure quality, measured using financial statement disaggregation disclosure and analyst forecast disclosure. Empirically, we validate that CFO power, measured by multiple dimensions, is positively associated with firms’ disclosure quality. We also find that this positive association between CFO power and disclosure quality is stronger when firms exhibit higher governance monitoring and accounting quality. Further analysis shows that our main results hold across multiple disclosure quality tests. Our findings are robust to addressing endogeneity issues using two-stage least squares, Heckman selection bias, and propensity score matching analyses. The results highlight the importance of CFO power for the accounting reporting process and decision-making.     

美元霸权与中国崛起——兼论如何应对美国强制人民币升值

作为与黄金脱钩的世界货币,美国倚仗美元霸权绝对的融资优势,可以轻松地收购世界各国经济的关键部门,支撑为维护帝国而花费的庞大军事开支。在当前美国等西方经济陷入长期停滞之际,国际金融资本的下一步目标直指中国。美国对中国发动经济战争的最终目的,是取得对中国经济制高点的控制权,从而取得对中国资产的控制权,这既可以消除中国经济增长对美国霸权地位的威胁,又可以享有中国经济增长的好处。美国实现这一目标最重要的步骤是要中国放弃金融主权,进一步推动金融自由化。这是美国对中国发动汇率战的真实背景。为应对国际金融资本的进攻,中国应采取包括回购外资企业在内的一系列政策措施。     

The Effects of Idealized Advertising Imagery on Social Comparisons,Psychological and Emotional Outcomes,and Consumer Vulnerability: A Conceptual Model

This article integrates marketing and social psychology theories and findings into a conceptual model that describes the conditions for which idealized advertising images induce positive (or negative) consumer outcomes. Extending Bessenoff's moderated mediation model, the authors propose that: (1) effect of social comparison on the relationship between exposure to idealized advertising images and psychological/emotional outcomes will be moderated by internalization of ideals and self-discrepancy; (2) effect of psychological/emotional outcomes on the relationship between social comparison and consumer vulnerability will be moderated by attainability of ideals; and (3) product claims should moderate the relationship between psychological and emotional outcomes and consumer vulnerability.     

Steven Levitt on Abortion and Crime: Old Economics in New Bottles

This article explores the work of Steven Levitt on abortion and crime as representative of a new wave of economists that are redefining the mainstream of the discipline. Levitt has moved away from formalized modeling of narrow self‐interested maximization that was a hallmark of the “old” mainstream. However, he retains the “old” mainstream linchpins of a focus on the individual by abstracting from the social context, and an emphasis on the ability of econometric testing to reveal the truth. These crucial elements that Levitt retains from the “old” mainstream create some problems of both emphasis and analysis for his explanation for the drop in crime in the United States.     

When discretion is better: Initial conditions and the timeless perspective

The predictive ability of technical trading rules and the presence of calendar anomalies are well known, but theoretically anomalous, features of equity markets. We show that while some rules exploit calendar effects they are primarily being driven by other factors.     

An economic evaluation of bushfire prevention and suppression

The Fire Management Program (FMP) of the Victorian Department of Natural Resources and Environment is responsible for the prevention and suppression of fires on public land in the State of Victoria. This article reports on an economic evaluation of the net benefits of these fire management activities for a representative year. The FMP is calculated to yield high net benefits to Victoria from its investment in fire suppression and prevention, through a reduction in the value of agricultural, capital and forest assets which would otherwise be lost to bushfires.
