Scientists as Midwives to Cluster Emergence: An Institutional Work Framework
The question of how embedded actors can create institutions that support cluster emergence remains unsolved in the cluster and national innovation systems literature. The present paper extends the recent literature on institutional entrepreneurship and institutional work to solve this paradox of embedded agency in the context of science-based clusters. Building on a longitudinal single case study of a functional foods cluster in Finland, we present an institutional work framework for cluster formation. We argue that, in addition to ideational, material and bridging work, authentic leadership work is critical for cluster emergence. The results of the study highlight the opportunities that scientists have to act as midwives to cluster formation, but they also show that well-functioning clusters need a broader support base.Peer reviewe
Wages in high-tech start-ups - do academic spin-offs pay a wage premium?
Due to their origin from universities, academic spin‐offs operate at the forefront of the
technological development. Therefore, spin‐offs exhibit a skill‐biased labour demand, i.e. spin‐offs
have a high demand for employees with cutting edge knowledge and technical skills. In order to accommodate
this demand, spin‐offs may have to pay a relative wage premium compared to other
high‐tech start‐ups. However, neither a comprehensive theoretical assessment nor the empirical
literature on wages in start‐ups unambiguously predicts the existence and the direction of wage differentials
between spin‐offs and non‐spin‐offs. This paper addresses this research gap and examines
empirically whether or not spin‐offs pay their employees a wage premium. Using a unique linked
employer‐employee data set of German high‐tech start‐ups, we estimate Mincer‐type wage regressions
applying the Hausman‐Taylor panel estimator. Our results show that spin‐offs do not pay a
wage premium in general. However, a notable exception from this general result is that spin‐offs that
commercialise new scientific results or methods provide higher wages to employees with linkages to
the university sector – either as university graduates or as student workers
Genome-wide analysis of allelic imbalance in prostate cancer using the Affymetrix 50K SNP mapping array
Prostate cancer (PCa) is the most commonly diagnosed non-cutaneous cancer in male subjects in Western countries. The widespread use of prostate-specific antigen (PSA) has increased the detection of this cancer form in earlier stages. Moreover, it has increased the need for new diagnostic procedures to be developed for patient stratification based on risk of progression. We analysed laser-microdissected prostate tumour tissue from 43 patients with histologically verified PCa, using the new high-resolution Affymetrix Mapping 50K single-nucleotide polymorphism array. The results showed six major loss of heterozygosity regions at chromosomes 6q14–16, 8p23–11, 10q23, 13q13–21 and 16q21–24 and a novel region at chromosome 21q22.2, all of which reveal concomitant copy number loss. Tumour development was further characterised by numerous novel genomic regions almost exclusively showing copy number loss. However, tumour progression towards a metastatic stage, as well as poor differentiation, was identified by specific patterns of copy number gains of genomic regions located at chromosomes 8q, 1q, 3q and 7q. Androgen ablation therapy was further characterised by copy gain at chromosomes 2p and 10q. In conclusion, patterns of allelic imbalance were discovered in PCa, consisting allelic loss as an early event in tumour development, and distinct patterns of allelic amplification related to tumour progression and poor differentiation
Complementarities between Barriers to Innovation: Data Evidence from Poland
This paper investigates the barriers to innovation perceived by Polish manufacturing firms. It refers to the heterogeneity of innovation active firms. We introduce a taxonomy of innovative firms based on the frequency with which they introduce commercialised innovations using data from both CIS4 (for 2002-2004) and CIS5 (2004-2006). Two groups of innovation-active firms are distinguished: those which introduced innovation in both periods covered by both CIS (which we call persistent innovators) and those which introduced innovation either in CIS4 or CIS5 (which we call occasional innovators). We use a four step analysis covering binary correlations, Principal Component Analysis, probit model and correlations of disturbances. Two types of explanatory variables describing firms' characteristics and innovation inputs used are considered. The paper shows that there are considerable differences in sensitivities to the perception of innovation barriers and in complementarities among barriers between persistent and occasional innovators. In the case of occasional innovators, a kind of innovation barrier chain is observed. This has an impact on differences in the frequency of innovation activities between the two groups of innovators and results in a diversification of innovators
The Importance of Equity Finance for R&D Activity – Are There Differences Between Young and Old Companies?
This paper analyzes the importance of equity finance for the R&D activity of small and medium-sized enterprises. We use information on almost 6000 German SMEs from a company survey. Using the intensity of banking competition at the district level as instrument to control for endogeneity, we find that a higher equity ratio is conducive to more R&D for young but not for old companies. Equity may be a constraining factor for young companies which have to rely on the original equity investment of their owners since they have not yet accumulated retained earnings and can relay less on outside financing. The positive influence is found for R&D intensity but not for the decision whether to perform R&D. Equity financing is therefore especially important for the most innovative, young companies
Foreign ownership, bank information environments, and the international mobility of corporate governance
This paper investigates how foreign ownership shapes bank information environments. Using a sample of listed banks from 60 countries over 1997–2012, we show that foreign ownership is significantly associated with greater (lower) informativeness (synchronicity) in bank stock prices. We also find that stock returns of foreign-owned banks reflect more information about future earnings. In addition, the positive association between price informativeness and foreign ownership is stronger for foreign-owned banks in countries with stronger governance, stronger banking supervision, and lower monitoring costs. Overall, our evidence suggests that foreign ownership reduces bank opacity by exporting governance, yielding important implications for regulators and governments
