Do the world’s largest cities follow Zipf’s and Gibrat’s laws?

We examine whether the size distribution and the growth process of the world’s largest cities follow Zipf’s law and Gibrat’s law. The parametric results of the size distribution analysis reject Zipf’s law for all sample sizes and also show the Zipf exponent systematically declines as the sample size increases. The growth process analysis confirms Gibrat’s law and yields a local Zipf exponent of one for cities with a normalized population less than 0.53%, which includes about 95% of the total observations. The deviations from Zipf’s law occur at the extreme upper tail and are likely a result of restricted mobility of population across countries. However, given that Gibrat’s law holds, we can expect the size distribution to converge to Zipf’s law with a decline in the barriers to immigration.     

Retaining volunteers for the cause: Hope and pride associated with cause-related charity events in cancer control

Special charity events are an important source of revenue for non-profit organisations in cancer control yet volunteering is declining and turnover is high. Experiences at cause-related events may influence retention, particularly emotions connected to the cause and ceremonies which honour cancer survivors and remember loved ones. We explore the degree to which emotions associated with cause-related volunteering and collective action in the literature are felt in response to Relay For Life and what emotions predict three indicators of retention: intention to return for future events, satisfaction with volunteering, and organisational commitment. Volunteers (n = 410) completed a cross-sectional survey at Relay For Life events in Queensland, Australia. Multiple regression analyses examined whether emotions associated with events predicted each indicator of retention, adjusting for number of years spent volunteering for events. Sixty-two percent reported an intention to return the following year. The most commonly reported event-related emotions were hope, pride, and empathy (62–69%). Intention to return, satisfaction, and commitment were each significantly predicted by hope and pride. The findings suggest special charity events in cancer control could retain volunteers by fostering pride and hope (e.g., for a cancer free future); however, future prospective research which examines the mechanisms of these relationships is warranted.     

Impact of Regulatory Enforcement on Leakages Prior to Analyst Recommendations

The financial press suggests that information is commonly leaked prior to analyst recommendations. We examine the impact that three regulatory actions (Regulation Fair Disclosure, Global Analysts Research Settlement, and the legal case against Galleon Group) have on information leakage prior to analyst recommendations. We find that all three regulatory actions have significantly reduced the leakage of information prior to analyst recommendations, even after controlling for several characteristics that explain the variation in information leakage. Our results are robust when applying an alternative method of measuring information leakage, and when forming various samples of analyst recommendations based on different criteria.

Toward a More Phronetic Leisure Science

In this essay, we examine the assumptions underlying natural science, social science, and the humanities. More specifically, we suggest that social science in general and leisure science in particular be guided by a different set of assumptions than those guiding natural science and the humanities. Drawing on the Aristotelian idea of phronesis, we propose that value rationality more so than instrumental rationality guide social scientific inquiry, and that social science in general, and leisure science in particular, be viewed as a bridge between natural science and the humanities.     

Accounting and networks of corruption

This study examines the nature and role of accounting practices in a network of corruption in an influence-market setting. The study focuses on the Canadian government’s Sponsorship Program (1994–2003), a national unification scheme that saw approximately $50 million diverted into the bank accounts of political parties, program administrators, and their families, friends and business colleagues. Relying on the institutional sociology of Bourdieu, the study demonstrates the precise role of accounting practices in the organization of a corrupt network imbued with a specific telos and certain accounting tasks. The study illustrates how accounting is accomplished and by whom, and it shows how the ‘skillful use’ of accounting practices and social interactions around these practices together enable corruption. In so doing, the study builds on a growing body of work examining criminogenic networks and the contextual, collaborative and systemic uses of accounting in such networks.     

Statistical Analysis of Choice Experiments and Surveys

Measures of households' past behavior, their expectations with respect to future events and contingencies, and their intentions with respect to future behavior are frequently collected using household surveys. These questions are conceptually difficult. Answering them requires elaborate cognitive and social processes, and often respondents report only their “best” guesses and/or estimates, using more or less sophisticated heuristics. A large body of literature in psychology and survey research shows that as a result, responses to such questions may be severely biased. In this paper, (1) we describe some of the problems that are typically encountered, (2) provide some empirical illustrations of these biases, and (3) develop a framework for conceptualizing survey response behavior and for integrating structural models of response behavior into the statistical analysis of the underlying economic behavior.
