Violent conflict and economic growth: Some time-series evidence

This paper uses time-series methods to examine interrelationships between growth and violent conflict in Sub-Saharan Africa. Results show bidirectional causalities, but the key determinant of conflict risk is prior conflict experience, not fluctuations in economic growth.     

Computer conferencing: Assessing the social impact of a new communications medium

Computer conferencing is a new communications technology which will affect the efficiency and quality of decision-making processes within existing groups and institutions. By removing most of the barriers to communication created by space and time, it may also facilitate the emergence of new life styles and organizational forms. However, like most technological advances, it is liable to have dysfunctions as well as advantages. A review of the literature on small group communications experiments serves as the basis for deriving a set of hypotheses about the effects of computer conferencing upon interaction processes within problem-solving groups. The uniqueness of this form of communication and the convenience offered suggest that it will ultimately have significant impacts at the societal level. Planned strategies for testing these hypotheses through field trials, surveys, and laboratory experiments are described.     

Repatriation and short-term assignments: an exploration into expectations,change and dilemmas

The aim of this research was to use in-depth interviews and discourse analysis to explore talk about repatriation expectations by 22 participants who were currently on, or had recently completed a short-term assignment within a single MNC. This study is one of the first to focus specifically on repatriation connected to short-term assignments and present findings that stem solely from the expatriates' perspective. Through discourse analysis, this paper outlines a framework with which to understand the relevance and meaning of individual change associated with career-based expectations of repatriation. For some of the participants, expectations of short-term assignment repatriation meant a desired change in work based on perceptions of themselves as changed as a result of their experience. For others, expectations of consistency as opposed to change between pre-and post-assignment work roles emerged through discourses of resistance. These findings raise a number of distinctively novel HR challenges.     

Why is there money? Endogenous derivation of `money' as the most liquid asset: a class of examples

Summary. The monetary character of trade, use of a common medium of exchange, is shown to be an outcome of an economic general equilibrium. Monetary structure can be derived from price theory in a modified Arrow-Debreu model. Two constructs are added: transaction costs and market segmentation in trading posts (with a separate budget constraint at each transaction). Commodity money arises endogenously as the most liquid (lowest transaction cost) asset. Government-issued fiat money has a positive equilibrium value from its acceptability for tax payments. Scale economies in transaction cost account for uniqueness of the (fiat or commodity) money in equilibrium.

Investigations of sexual harassment allegations: Legal means fair—or does it?

Sexual harassment investigations are among the most sensitive and explosive of all HR activities, yet HR managers typically do not receive training in how to conduct these investigations. As a result, and despite the best efforts of the HR manager, the parties involved often believe they were not treated fairly. Our article focuses on the central question of providing fair treatment during the emotionally charged atmosphere of a sexual harassment investigation. We integrate the organizational justice literature with case law and move through five “stages” of an investigation. Lessons in each stage are highlighted, dilemmas are discussed, and guidelines are offered. © 2000 John Wiley & Sons, Inc.     

QUALITATIVE AND MIXED‐METHODS RESEARCH IN ECONOMICS: SURPRISING GROWTH,PROMISING FUTURE

Qualitative research in economics has traditionally been unimportant compared to quantitative work. Yet there has been a small explosion in use of quantitative approaches in the past 10–15 years, including ‘mixed‐methods’ projects which use qualitative and quantitative methods in combination. This paper surveys the growing use of qualitative methods in economics and closely related fields, aiming to provide economists with a useful roadmap through major sets of qualitative methods and how and why they are used. We review the growing body of economic research using qualitative approaches, emphasizing the gains from using qualitative‐ or mixed‐methods over traditional ‘closed‐ended’ approaches. It is argued that, although qualitative methods are often portrayed as less reliable, less accurate, less powerful and/or less credible than quantitative methods, in fact, the two sets of methods have their own strengths, and how much can be learned from one type of method or the other depends on specific issues that arise in studying the topic of interest. The central message of the paper is that well‐done qualitative work can provide scientifically valuable and intellectually helpful ways of adding to the stock of economic knowledge, especially when applied to research questions for which they are well suited.     

The impact of group formation in a cooperative learning environment

Research indicates that cooperative learning (CL) has the potential to increase accounting student satisfaction without impairing the learning of technical material (Lancaster, K., & Strand, C. (2001). Using the team-learning model in a managerial accounting class: An experiment in cooperative learning. Issues in Accounting Education, 16(4), 549–567). This study investigates whether instructor-formed heterogeneous groups produce a more effective CL environment than student self-selected groups by measuring individual academic performance and perceptions. Results indicate the presence of a treatment interaction, implying that the best group composition may not be the same for all students. In some circumstances, higher ability students had statistically higher performance in more homogeneous groups. Lower ability students did better (not significant) in heterogeneous groupings. The majority of students gave high ratings to the impact of CL on learning and development of team skills. Students were only mildly interested in increasing the time spent in groups, indicating that they value both traditional teaching methods and CL.     

Liquidity of secondary capital markets: Allocative efficiency and the maturity composition of the capital stock

Summary We investigate the function of liquid financial markets for the allocation of productive capital. We consider an economy where agents endogenously choose among capital production technologies with differing gestation periods. Long-gestation capital investments must be rolled-over in secondary capital markets. The use of such investment technologies therefore requires the support of liquid financial markets. We investigate how changes in the liquidity of these markets (i.e., in the costs of transacting) affect (a) the choice of capital production technology, (b) per capita income and the per capita capital stock, (c) the level of financial market activity, (d) the real return on savings and (e) welfare in a steady state equilibrium. Improvements in financial market liquidity raise rates of return on savings, and favor the increased use of long gestation capital investments. However, such improvements may or may not lead to higher levels of real activity or steady state welfare. We describe conditions under which various outcomes occur.We have benefited from the comments of seminar participants at the Board of Governors of the Federal Reserve System, the Federal Reserve Bank of Minneapolis, the International Monetary Fund, Berkeley, Boston College, Boston University, Brown, Chicago, Illinois, Miami, UC San Diego, Simon Fraser, University of British Columbia, University of Washington, Yale, the Canadian Macro Study Group Meetings, the Murrary S.

The fashion‐conscious behaviours of mature female consumers

Under‐appreciation of mature consumers as a numerous and comparatively wealthy market segment has resulted in not only lost revenues for business, but also lost consumption and service opportunities for the elderly. In response to expressed needs for more research into actual and desired consumption by older consumers, this study examined the apparel and shopping preferences of mature women in America. Independent living residents were surveyed concerning fashion consciousness, fashion information sources and shopping behaviours. Young and mature consumers’ reactions to female apparel ensembles were compared. Mature subjects purchased apparel for pleasure or need, but less for conformity. Decisions were influenced more by fit and comfort than by fashion, despite suggestions that dressing stylishly was important. New fashions were encountered via catalogue illustrations, social gatherings and window displays. Subjects high in fashion consciousness had greater financial and social involvement with fashion, greater chronological‐to‐cognitive age differences and larger clothing budgets. Young and mature consumers’ responses to apparel illustrations differed significantly. As the mature market expands, attention to age‐divergent definitions of fashion (such as those based upon admiration of comfort) will determine the success of apparel businesses. Assessment of cognitive age will facilitate identification of those mature consumers most predisposed toward fashion consumption.
