Contingent contingency: Knowledge heterogeneity and new product development performance revisited

This paper re-conceptualizes the meaning of knowledge heterogeneity—an important but under-developed collective-level concept that influences innovation. The new conceptualization extends the construct of knowledge heterogeneity beyond the traditional assessments of variability in professional background. This research further explores the quadratic relationship between knowledge heterogeneity and new product development performance. Drawing on and synthesizing knowledge clarity and uncertainty avoidance literature to consider work context, the possibility of a positive quadratic, rather than a linear or a negative quadratic, relationship between knowledge heterogeneity and innovation is suggested. This relationship is explored using data collected from 128 new product development teams from companies in knowledge-intensive and innovation-oriented industries located in Taiwan. Results are discussed in terms of the hypothesized positive quadratic relationship. The outcome of the study is discussed in terms of the influence of the knowledge structure and cultural factors, which suggest potential contingent contingencies across different contexts.     

Changes in National Technological Competitiveness: 1990, 1993, 1996 and 1999

Georgia Tech's Technology Policy and Assessment Center, with support from the US National Science Foundation, has been generating High-Tech Indicators (HTI) — measures of national technology-based export competitiveness since 1987. This paper reports the HTI results for 33 nations in 1999 in comparison with those of 1990, 1993 and 1996. HTI includes four 'input indicators' and a key 'output indicator' — technological standing. We construct a new composite input indicator here and examine its predictive capability. Input indicators for 1990 and 1993 show intriguing relationships to 1999 technological standing. We compare the indicators for various groups — leading and emerging Western economies, rapidly developing Asian economies, former Eastern Bloc nations and lagging Latin American countries. The USA presently exhibits a dominant position, but signs strongly point toward increasingly broad-based competition in technology-based products.     

TESTING FOR CHANGES IN THE STRUCTURE OF THE DEMAND FOR MEAT IN AUSTRALIA

Quarterly data from 1962 to 1983 for beef, lamb, mutton, pig meat and poultry were used to test for constancy in the structure of meat demand in Australia. The cumulative sum, cumulative sum of squares and Farley-Hinich tests were applied to a range of models to ensure that any rejection of stability was not due to an inappropriate functional form or omitted dynamics. Little evidence was found of a marked swing away from consumption of any meat, with the exception of mutton. The results suggest that changes in prices and in total consumer expenditure are far more important than changes in tastes as determinants of meat consumption.
