Mapping the innovation production process from accumulative advantage to economic outcomes: A path modeling approach

The research about the innovation production process (IPP) is burgeoning. Our understanding of the interdependent interactions between functionally distinct innovation activities during it from a systemic perspective is rather unclear, yet, which is beneficial to empirical innovation management. This study, based on systems thinking, presents a novel analytical framework to empirically and quantitatively map the IPP jointly associated with a path modeling approach, which helps in untangling the interactive mechanism between stage-specific innovation activities with distinct functions within an IPP from accumulative advantage to economic outcomes. We use the attractive analytical framework to guide an empirical investigation to the China's high-tech industries' IPP at the macro-regional level. Our empirical study confirms the dominant role of previous innovation capital accumulation in the whole IPP embedded into regional innovation systems of China's high-tech industries. That is, we prove the existence of accumulative advantage phenomenon in the regional IPP. The examination results show that there is a significant Matthew effect of technological innovation accumulation on technological innovation inputs as well as the Path dependence of technological innovation outputs/outcomes on technological innovation accumulation. This indicates that the innovation-practitioners should promote innovation capital accumulation for sustainable innovations and economic profits in a long time. At the same time, our findings suggest that, in order to alleviate the cross-regional unbalance of innovation development and promote radial innovations in China's high-tech industries, both policy-makers and innovation-practitioners should try to get rid of the dependence on the previous accumulated innovation capital.     

Growth and inequality: Dependence on the time path of productivity increases (and other structural changes)

This paper examines the significance of the time path of a given productivity increase on growth and inequality. Whereas the time path impacts only the transitional paths of aggregate quantities, it has both transitional and permanent consequences for wealth and income distribution. Hence, the growth-inequality tradeoff generated by a given discrete increase in productivity contrasts sharply with that obtained when the same productivity increase occurs gradually. The latter can generate a Kuznets-type relationship between inequality and per-capita income. Our results suggest that economies with similar aggregate structural characteristics may have different outcomes for income and wealth inequality, depending on the nature of the productivity growth path.

Possibilities for critical management education and studies

This research note builds upon recent discussions in this journal in an exploration of different scenarios for the way that critical management education and studies can relate to mainstream management education and studies. It is argued that there is no choice but for there to be a relationship of some sort between the two, albeit of a complex sort. Three scenarios are envisaged. In one, the two approaches largely ignore each other and their relationship is left tacit and covert. In the second, there is an engagement between the two. In the third, critical approaches gain ascendancy and become the mainstream. Whilst fraught with difficulties, the conclusion is that the second scenario, that of engagement, is preferable.     

Academic spin-offs at different ages: A case study in search of key obstacles to growth

Support to enhance early growth of academic spin-off firms is at the core of many economic policies. Efficiency of this support has been recently questioned due to slow growth of spin-off firms in various European countries. However, despite many studies to improve support, there is virtually no empirical insight into resistance of obstacles that constrain growth over time and how this differs between distinct types of spin-offs. This article explores the incidence and nature of obstacles to growth in a cross-section and longitudinal approach, and uses Delft University of Technology (the Netherlands) as a case study. We find evidence that (1) the overall ability to overcome obstacles decreases at the age of four, most probably reflecting the rise of the so-called credibility juncture, and that (2) highly innovative spin-offs start with an accumulation of obstacles but move relatively quickly to sustainable growth. The paper concludes with recommendations for the design of new (renewed) incubation policies and for further research.
