Analysis of ultra-high-frequency financial data using advanced Fourier transforms

This paper presents a novel application of advanced methods from Fourier analysis to the study of ultra-high-frequency financial data. The use of Lomb–Scargle Fourier transform, provides a robust framework to take into account the irregular spacing in time, minimising the computational effort. Likewise, it avoids complex model specifications (e.g. ACD or intensity models) or resorting to traditional methods, such as (linear or cubic) interpolation and regular resampling, which not only cause artifacts in the data and loss of information, but also lead to the generation and use of spurious information.     

Are Men Always Picked Over Women? The Effects of Employment Equity Directives on Selection Decisions

This study replicates and extends previous work by Oppenheimer and Wiesner [1990, Sex discrimination: Who is hired and do employment equity statements make a difference? Proceedings of the 11th Annual Conference of the Administrative Sciences Association of Canada, Personnel and Human Resources Division], and examined the effects of minority qualifications on hiring decisions, the effects of employment equity directives when minority candidates are less qualified and the effects of different types and strengths of employment equity directives on hiring decisions. The results indicate that when employment equity is in place, people are increasingly more likely to hire underrepresented group members, to the extent that they are more qualified. Men appear to be treated in a positively biased manner, and are more likely to be hired when they are less qualified. Women are less likely to be hired when they are under-qualified, and in the absence of employment equity directives or when there is a suggestion that women are underrepresented. Moreover, when␣employment equity directives are strengthened, there appears to be a subtle backlash for women but not for men. Eddy S. Ng is an assistant professor at Trent University.

Does corruption increase emerging market bond spreads?

We study the relationship between corruption and borrowing costs for governments and firms in emerging markets. Combining data on bonds traded in the global market with survey data on corruption compiled by Transparency International, we show that countries that are perceived as more corrupt must pay a higher risk premium when issuing bonds. The global bond market ascribes a significant cost to corruption: an improvement in the corruption score from the level of Lithuania to that of the Czech Republic lowers the bond spread by about one-fifth. This is true even after controlling for macroeconomic effects that are correlated with corruption. We find little evidence that investors became more sensitive to corruption in the wake of the Asian financial crisis.     

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.     

Thirlwall’s Law and the Stability of Export and Import Income Elasticities

The aim of this paper is to examine the stability of income elasticities used in Thirlwall's law to approximate a country's long-term growth and to see empirically how non-constancy will affect these predictions. For this purpose, three countries - Canada, New Zealand and the UK - are analysed, using annual time series data from 1973 to 1995. These three countries were chosen on the basis of their contrasting trade patterns. The results obtained are different for each country but they still suggest the predictive power of one of the two specifications of Thirlwall's law is good.     

Motivational bases for managing diversity: A model of leadership commitment

Given the limited effectiveness of equal employment opportunity and affirmative action programs in promoting minorities in the U.S., the onus to advance women and minority groups may depend on the voluntary efforts from corporate America. In this paper, we apply a general theory of commitment to help explain why top executives may be committed to managing diversity in organizations. We propose that top executive commitment can stem from instrumental, normative, or affective bases. Specifically, top executives may be motivated because of utility maximization, a moral obligation, or a personal desire to be associated with a program of social importance and/or to leave a positive legacy. We further explore the implications of the three motivational bases of top executive commitment to managing diversity on firm diversity outcomes, and we offer some propositions which can serve as a basis for future research.
