Risk processes analyzed as fluid queues

This paper presents the Laplace transform of the time until ruin for a fairly general risk model. The model includes both the classical and most Sparre-Andersen risk models with phase-distributed claim amounts as special cases. It also allows for correlated arrival processes, and claim sizes that depend upon environmental factors such as periods of contagion. The paper exploits the relationship between the surplus process and fluid queues, where a number of recent developments have provided the basis for our analysis.     

Agency / Client Relationshipsas Seen by Influential on Both Sides

Abstract

This article concerns a subject of interest and concern to both advertising agency executives and their clients; i.e., how the two of them feel about each other and themselves in terms of the agency/client relation-ship. These perceptions and feelings were gleaned from a survey of agency leaders and major users of agency services. Based on the findings, some suggestions and directions are offered for making the agency/client dyad more harmonious.     

The International Effects of China’s Growth,Trade and Education Booms

China’s international trade flows have increased by 500 per cent since 1992, far outstripping GDP growth. Likewise tertiary education enrolments have increased by 300 per cent. We simulate these changes using a multi‐sector growth model of the Chinese and USA economies. A decade of trade biased growth in China is found to raise USA GDP by approximately 3–4.5 percentage points and has a large impact on the demand for tertiary education in China. Despite these positive effects of growth, the results suggest that the expansion of China’s education sector per se has practically no long‐run impact on the USA economy.     

Learning from evaluation by peer team: a case study of a family counselling organization

This qualitative study explores how employees learn from Team Primacy Concept‐based employee evaluation and how they use the feedback in performing their jobs. Team Primacy Concept‐based evaluation is a type of multirater evaluation. The distinctive characteristic of such evaluation is its peer feedback component during which the employee's performance is discussed by peers in a face‐to‐face team setting. The study used Kolb's experiential learning model to describe the process by which employees learn from Team Primacy Concept‐based employee evaluation and the ways in which they use the knowledge to improve their job performance. The study found eight major dimensions that highlight employee learning as a result of the employees' engagement in the process of Team Primacy Concept‐based evaluation.     

Favor prevalence in emerging markets: A multi-level analysis

Favors are a medium of exchange for social capital. Social capital creates social, political, and economic benefits for individuals, organizations, communities, and societies around the world. Favors promote cooperation between individuals and are used to bond individual actors with other individuals, groups, communities, and institutions. Favors are prevalent in business in emerging markets because of the presence of institutional voids, limited social and geographic mobility, and strong reciprocity norms. Favors create benefits and liabilities for business organizations and their networks. They produce outcomes beyond the favor exchange process that can be characterized as productive or perverse. Despite their prevalence and importance, favors and their dynamics are not well understood. We explore the antecedents, content, process, and consequences of favors. We conclude our multi-level analysis of favors with a discussion of the “breakeven” point for favors—the point where favors tip from having a positive effect to having a negative effect on organization performance. We present an integrated framework to explain the dynamics of favors in emerging market business contexts, and develop propositions to guide future research.
