Improving the speed of adoption of agricultural technologies and farm performance through farmer groups: evidence from the Great Lakes region of Africa

The article examines the effect of membership in farmer groups (MFG) on adoption lag of agricultural technologies and farm performance in Burundi, the Democratic Republic of Congo and Rwanda. We use duration and stochastic production frontier models on farm household data. We find that the longer the duration of MFG, the shorter the adoption lag and much more so if combined with extension service delivery. Farmer groups function as an important mechanism for improving farm productivity through reduced technical inefficiency in input use. We discuss policy implications under which farmer groups are a useful channel to reduce adoption lag, and the means through which improved farm performance can be achieved.     

Does proximity matter in international bond underwriting?

In this study, we analyze a sample of 3982 international bond issues from 31 countries to examine the impact of geographic proximity on the selection of lead underwriter in the international bond market. We find that proximate banks are more likely to lead underwrite risky bonds and non-rated bonds. On average, the total issue cost is lower if the lead underwriter is a proximate bank. The overall results suggest that geographically proximate banks have better access to private information about issuing companies. We also find that the cost reduction effect of proximate underwriting only appears in developed markets. In addition, this cost reduction effect is relatively weak in countries with a legal system that provides good investor protection.     

Mortality transition and differential incentives for early retirement

Many studies specify human mortality patterns parametrically, with a parameter change affecting mortality rates at different ages simultaneously. Motivated by the stylized fact that a mortality decline affects primarily younger people in the early phase of mortality transition but mainly older people in the later phase, we study how a mortality change at an arbitrary age affects optimal retirement age. Using the Volterra derivative for a functional, we show that mortality reductions at older ages delay retirement unambiguously, but that mortality reductions at younger ages may lead to earlier retirement due to a substantial increase in the individual?s expected lifetime human wealth.     

Effects of Supplier and Customer Integration on Product Innovation and Performance: Empirical Evidence in Hong Kong Manufacturers

While the beneficial impacts of supplier and customer integration are generally acknowledged, very few empirical research studies have examined how an organization can achieve better product performance through product innovation enhanced by such integration. This paper thus examines the impact of key supplier and customer integration processes (i.e., information sharing and product codevelopment with supplier and customer, respectively) on product innovation as well as their impact on product performance. It contributes to existing literature by asking how such integration activities affect product innovation and performance in both direct and indirect ways. After surveying 251 manufacturers in Hong Kong, this study tested the relationships among information sharing, product codevelopment, product innovativeness, and performance with three control variables (i.e., company size, type of industry, and market certainty). Structural equation modeling with correlation and t‐tests was used to test the hypothesized research model. The findings indicate a direct, positive relationship between supplier and customer integration and product performance. In particular, this study verifies that sharing information with suppliers and product codevelopment with customers directly improves product performance. In addition, this study empirically examines the indirect effects of supplier and customer integration processes on product performance, mediated by innovation. This has seldom been attempted in previous research. The empirical findings show that product codevelopment with suppliers improves performance, mediated by innovation. However, the sampled firms cannot improve their product innovation by sharing information with their current customers and suppliers as well as codeveloping new products with the customers. If the adoption of supplier and customer integration is not cost free, the findings of this study may suggest firms work on particular supplier and customer integration processes (i.e., product codevelopment with suppliers) to improve their product innovation. The study also suggests that companies codevelop new products only with new customers and lead users instead of current ones for product innovation. For managers, this study has demonstrated that both information sharing and product codevelopment affect performance directly and indirectly. Managers should put more emphasis on these key processes, especially when linked with product innovation. Managers should consider involving their suppliers and customers in the early stages of design. Information sharing with suppliers is also important in product development. As suggested by this study, extensive effort on supplier and customer integration should be made to directly augment current product performance and product innovation at the same time.     

Organisation development practices in Hong Kong: Current state and future challenges

This paper examines the current state of OD practices in Hong Kong. The results of two recent studies among major firms and among the managers of large firms are reported. It is found that Hong Kong firms put more emphasis on the human processual type of interventions, followed by strategic planning. Some firms are practising state-of-the-art OD activities, though the majority are still using traditional OD interventions. The current state of OD practice is then reviewed and implications for the future are discussed.The author is from the Department of Management, The Chinese University of Hong Kong.

Some problems with transient phenomena when simulating unpaced lines

Unlike earlier simulation studies of unpaced production lines which generally concentrated on steady-state behavior, we are concerned with their transient characteristics. This paper (1) presents an approach for studying and monitoring transient behavior, (2) reports some important transient operating characteristics previously overlooked, and (3) demonstrates that the conflicting results reported in some of the earlier simulation studies are due to an inadequate accounting for transient behavior. Thus, this paper illustrates the importance of having a better understanding of transient behavior in unpaced lines, and presents our initial steps towards dealing with it.     

The role of organisational concern for workplace fairness in the choice of a performance measurement system

Prior studies linking performance management systems (PMS) and organisational justice have examined how PMS influence procedural fairness. Our investigation differs from these studies. First, it examines fairness as an antecedent (instead of as a consequence) of the choice of PMS. Second, instead of conceptualising organisational fairness as procedural fairness, it relies on the impression management interpretation of organisational fairness. Hence, the study investigates how the need of senior managers to cultivate an impression of being fair is related to the choice of PMS systems and employee outcomes. Based on a sample of 276 employees, the results indicate that the need of senior management to cultivate an impression of being fair is associated with employee performance. They also indicate that a substantial component of these effects is indirect through the choice of comprehensive performance measures (CPM) and employee job satisfaction. These findings highlight the importance of organisational concern for workplace fairness as an antecedent of choice of CPM. From a theoretical perspective, the adoption of the impression management interpretation of organisational fairness contributes by providing new insights into the relationship between fairness and choice of PMS from a perspective that is different from those used in prior management accounting research.
