An investigation of the use of global, virtual, and colocated new product development teams

This paper presents the results of an investigation of differences between global, virtual and colocated new product development (NPD) teams. Specifically, we examined whether and how these three types of teams differed in terms of usage, challenges, and performance. A survey of PDMA members was undertaken to collect the data. Out of 103 firms participating in the survey, 54 had used or were using global teams for some of their NPD efforts. Overall, we found that the use of global teams in our respondent firms is rapidly increasing. Our respondents indicated that by the year 2001, approximately one out of every five NPD teams in their companies are likely to be global. However, our respondents also expect that their companies will be using multiple types of teams that is, global, virtual, and colocated, to develop their new products. Our findings also suggest that global teams generally face greater behavioral and project management challenges than either colocated or virtual teams. Global team performance is also lower than the performance of virtual or colocated teams. Are these challenges associated with poorer performance? In examining this question, our results suggest that greater project management challenges are associated with lower performance, for all three types of teams. Surprisingly, behavioral challenges were not associated with performance for any team type. Our results suggest that firms face different problems associated with managing each type of NPD team—global, virtual and colocated. To effectively manage each type of team may, in turn, require that companies and their managers employ different solutions to these different problems. Additionally, companies may find that the preparation they provide to their managers and team members to work in these different team environments may also need to be different. Further research is clearly needed to address these managerial implications.     

The determinants of Latin American exchange rate regimes

The experience of the last thirty years suggests that a wide range of factors affects policymakers’ choice of exchange rate regime. The initial explanation was that changes in the international sphere dominated domestic policies and strongly influenced how governments decided among the trade-offs. More recently, domestic political factors’ influence on the choice of exchange rate regimes have been emphasized, providing detailed and rich insights into the dynamics of the choice. Neither approach has been entirely successful. Both internal and external factors must be taken into account. This article builds on previous empirical work and takes into account domestic and international influences on the choice of exchange rate regimes in Latin America between 1964 and 1996. In addition, we highlight a variety of ‘interactions’, choices of economic policy that are affected by both national and international pressures and that, in turn, influence the choice of exchange rate regime. The empirical model uses multinomial ordered logit analysis to determine the factors in exchange rate determination and to compare the explanatory of the models with and without the interaction variables.     

Input and output technical efficiencies of wheat production in Kerman, Iran

The Iranian government encourages farmers to produce wheat (a common agricultural enterprise) by increasing farm productivity and efficiency. In this paper, using a Cobb–Douglas frontier production function, a simple relationship between a farm‐level output‐based technical efficiency measure (the Timmer index) and an input‐based measure (the Kopp index) is first developed. Then, using 1995 data from 164 farms in Kerman province, Iran, the average Timmer and Kopp indexes were estimated at 0.93 and 0.91, respectively, and were found to be similarly affected by farm size (positively up to about 9 ha) and by input ratios, though with rather small explanatory power. Thus, there seems some but limited scope to increase the profitability of Iranian wheat production either by increasing the product, given input levels, or by decreasing inputs for the current level of wheat production. However, since wheat producers may be able to adapt their production process more easily and quickly by implementing new techniques, i.e. by more efficient combination of inputs, than by adopting new technology, correction of input over‐use can be regarded as a policy with speedy if limited effect in this case.     

1929：美国股市大崩盘

根据当时对时局的普遍看法，1929年秋天，美国经济彻底陷入了萧条。6月，工业与工厂生产指数双双达到最高点，然后开始一路下滑。10月，联邦储备工业生产指数由4个月前的126点下降到了117点。钢铁产量从6月份开始一路下滑；10月，铁路运输量减少；住宅建设这个易变的产业几年来持续低迷，而1929年仍继续下滑。     

Repetition and signalling: experimental evidence from games with efficient equilibria

We report experiments where subjects generally fail to attain the efficient equilibrium of a one-shot game, but attain the efficient equilibrium of the repeated version. The results suggest that in the repeated game actions are used to signal future intentions.
