Managerial Intentions and Wage Determination in the Canadian Petroleum Industry

Scant attention has been given to the impact of managerial objectives on wage policies. This study demonstrates that in the Canadian petroleum industry, which has minimal wage dispersion, managerial objectives—in particular, a tendency toward imitative behavior and a strategy of union avoidance—do affect wage determination.     

Asymptotic behavior of the estimated weights and of the estimated performance measures of the minimum VaR and the minimum CVaR optimal portfolios for dependent data

In this paper we derive the asymptotic distributions of the estimated weights and of estimated performance measures of the minimum value-at-risk portfolio and of the minimum conditional value-at-risk portfolio assuming that the asset returns follow a strictly stationary process. It is proved that the estimated weights as well as the estimated performance measures are asymptotically multivariate normally distributed. We also present an asymptotic test for the weights and a joint test for the characteristics of both portfolios. Moreover, the asymptotic densities of the estimated performance measures are compared with the corresponding exact densities. It is shown that the asymptotic approximation performs well even for the moderate sample size.     

Work-related acculturation: change in individual work-related cultural values following immigration

The effects of culture in the workplace have been well documented. Because cultures vary across countries, business practices that are effective in some regions may not be effective in others. While cross-country cultural differences have been explored in depth, little is known about cultural variations and dynamics in the context of immigration. On the basis of a multilevel study of 2163 immigrants and locals residing in Canada, we investigate (1) patterns of immigrant acculturation; (2) the relationship between acculturation of visible elements of culture, such as language proficiency or cuisine and music tastes, and acculturation of tacit cultural values and (3) individual- and group-level predictors and moderators of acculturation. The results are discussed with a focus on implications for practitioner managers and immigration policy makers.     

Econometrical analysis of the sample efficient frontier

The efficient frontier is a parabola in the mean-variance space which is uniquely determined by three characteristics. Assuming that the portfolio asset returns are independent and multivariate normally distributed, we derive tests and confidence sets for all possible arrangements of these characteristics. Note that all of our results are based on the exact distributions for a finite sample size. Moreover, we determine a confidence region of the whole efficient frontier in the mean-variance space. It is shown that this set is bordered by five parabolas.     

‘Shopping for Voice’: Do Pre‐Existing Non‐Union Representation Plans Matter When Employees Unionize?

The transition to unionization in three workplaces with pre‐existing non‐union employee representation plans (NERPs) is contrasted to three matched sites, which had only individual representation. Pre‐existing collective voice arrangements had substantial effects on the process and outcomes of unionization. While the individual representation sites presented a conventional process of mobilization and attachment to the union, the NERP sites revealed a more equivocal outcome. The union was used in an instrumental manner to increase NERP power and to achieve worker demands already articulated by the NERP. NERP leaders became union leaders. There remained significant attachment to the NERP and a reluctance to fully embrace unionization.     

Disability and the Performance Paradox: Can Social Capital Bridge the Divide?

This research captures the physical and social experience of disability by analysing the practical performance problems that arise when an ill or injured employee returns to work, and documenting how those problems are interpreted. The grounded theory approach suggests an alternative to the traditional biomedical or social perspectives on disability. Field research reveals four themes: attendance, disciplinary history, peer interaction and task function. Managerial and co‐worker perceptions were significantly affected by interactions that occurred before any disability was known to exist. Historic patterns of social exchange strongly suggest that social capital theory explains problematic work performance.     

Impact of Retail Internationalization on Agribusiness: The Case of Ukraine

This article aims to reveal the impact of the retail internationalization process on the Ukrainian agribusiness. Building on an in-depth survey, we delineate major changes that occur owing to the process. Talking about global retailers, an essential part of their business is connected with selling high-quality products. Because (food) quality and thereby food safety processes are considered to be the highest priority, we concentrate on the agri-food business. Our interest in Ukraine is kindled by ongoing verticalization addressed by foreign retailers and imitated by local firms. As a result, overall quality improvements are observed.
