Prior studies show that the success of firms in industrial clusters is the result of two main reasons; the transfer of knowledge and routines from parent firms to spinoffs that locate in the same locality, and the returns from co-location. While previous research has largely inferred the presence of parent-spinoff networks, few studies have measured them. Furthermore, the lack of geographic precision has led to conflicting results for evidence of returns from location, as the gains from geographic proximity may not always be linear. This paper introduces network measurement and a refined geographic measure to separate these two respective channels of knowledge transfer, and analyzes their impact on firm survival (as a proxy for firm success). It is found that the gains with respect to location are nonlinear. Furthermore, a firm’s historical links formed through parent-spinoff linkages have a significant impact on survival, which differ depending on the motivations of the entrepreneur. Moreover, these channels of knowledge are complementary in nature.

Wage employment is the most commonly observed type of employment after a spell of entrepreneurship. The purpose of this paper is to investigate the effects of having been an entrepreneur on earnings after individuals exit. The question is how the entrepreneurship spell influences their value in the labor market? Based on a theoretical framework and earlier literature, our specific interest lies in how these outcomes interact with education level and the nature of the entrepreneurial venture. To investigate this question, we use longitudinal register data on firms and individuals in Sweden. The empirical strategy builds on matching techniques and estimations of earnings equations in a difference-in-differences framework with heterogenous treatment years. We provide evidence that there exists an earnings penalty when highly educated entrepreneurs return to wage employment. This effect is persistent throughout the time period that we observe. For individuals with lower educational attainment, we find no or weak evidence of a wage penalty. Our results suggest that the wage penalty for highly educated individuals operates through the depreciation of specific specialized skills valuable in wage employment.

Fundamental correspondence and analogies between the evolution of technological and biological innovations call for an ‘innovation Darwinian’, ‘universal Darwinian’ or ‘memetic’ approach to understanding technology innovation. Neo-institutional, in fact pseudo-Lamarckian evolutionary economic theory, represented by North, Nelson and Winter, Freeman and others, is criticized. Pseudo-Lamarckian (“by volition”) evolution is explained and analyzed on Darwinian grounds (as intentional and artificial selection), as is Schumpeter’s definitions of creative and imitative innovation. Data from a web survey among Swedish public and private organizations in 1999 are studied. Data show that Darwinian co-evolutionary interaction between producers and users or clients provide essential conditions and stronger influence on creative IT innovations than both ‘Lamarckian’ strategies and competition.

The Hydrogen Illusion (2022) is a self-published book by Samuel Furfari, a retired chemical engineer who worked for 36 years in energy policy at the European Commission. Hydrogen has been brought to the forefront of environmental policy in recent years as the EU and other Western economies are allocating billions of euros and dollars towards hydrogen production. Furfari argues that this is a mistake, and that hydrogen has little potential as an energy form, primarily as it requires so much energy in order to be produced. While at times technical and difficult to follow, The Hydrogen Illusion is a valuable contribution to the ongoing debate about how Western economies can combine economic and environmental development.
