Science and Technology Cooperation in Cross-border Regions::A Proximity Approach with Evidence for Northern Europe
Given the sheer number of cross-border regions (CBRs) within the EU, their socio-economic importance has been recognized both by policy-makers and academics. Recently, the novel concept of cross-border regional innovation system has been introduced to guide the assessment of integration processes in CBRs. A central focus of this concept is set on analyzing the impact of varying types of proximity (cognitive, technological, etc.) on cross-border cooperation. Previous empirical applications of the concept have, however, relied on individual case studies and varying methodologies, thus complicating and constraining comparisons between different CBRs. Here a broader view is provided by comparing 28 Northern European CBRs. The empirical analysis utilizes economic, science and technology (S&T) statistics to construct proximity indicators and measures S&T integration in the context of cross-border cooperation. The findings from descriptive statistics and exploratory count data regressions show that technological and cognitive proximity measures are significantly related to S&T cooperation activities (cross-border co-publications and co-patents). Taken together, our empirical approach underlines the feasibility of utilizing the proximity approach for comparative analyses in CBR settings
The Accounting Network: how financial institutions react to systemic crisis
The role of Network Theory in the study of the financial crisis has been
widely spotted in the latest years. It has been shown how the network topology
and the dynamics running on top of it can trigger the outbreak of large
systemic crisis. Following this methodological perspective we introduce here
the Accounting Network, i.e. the network we can extract through vector
similarities techniques from companies' financial statements. We build the
Accounting Network on a large database of worldwide banks in the period
2001-2013, covering the onset of the global financial crisis of mid-2007. After
a careful data cleaning, we apply a quality check in the construction of the
network, introducing a parameter (the Quality Ratio) capable of trading off the
size of the sample (coverage) and the representativeness of the financial
statements (accuracy). We compute several basic network statistics and check,
with the Louvain community detection algorithm, for emerging communities of
banks. Remarkably enough sensible regional aggregations show up with the
Japanese and the US clusters dominating the community structure, although the
presence of a geographically mixed community points to a gradual convergence of
banks into similar supranational practices. Finally, a Principal Component
Analysis procedure reveals the main economic components that influence
communities' heterogeneity. Even using the most basic vector similarity
hypotheses on the composition of the financial statements, the signature of the
financial crisis clearly arises across the years around 2008. We finally
discuss how the Accounting Networks can be improved to reflect the best
practices in the financial statement analysis
Collective frames of reference, recognition, and managers' mental models of competition: a test in two industries
This work was supported by ESRC grant no. R000232883.Managers draw upon sources of collective knowledge to cognitively represent strategic
issues. It has also be argued that cognition is embedded in social interaction, enabling
managers to recognize of othersâ cognitions. In two separate industries, this study found
that the influences upon managersâ mental models of their competitive environment include
industry membership, organizational membership, and management level. The results
indicate further that recognition of othersâ mental models may be more pronounced than
cognitive similarity.School of Managemen

Antecedents of trust in international joint ventures' (IJVS) performance in developing countries: A review of empirical evidence
Trust in international joint venture has received much attention for the last 20 years. This study highlights the importance of social capital in international joint ventures (IJVs) in developing countries. This paper assesses the impact of antecedents of trust on performance of international joint ventures in developing countries, which is based on social exchange theory. Little attention has been paid to exploring the concept in IJV. The impacts of components of inter partner-fits and relational factors on trust and the effect of trust on performance of IJVs will be considered. In addition the impact of religion and country risk on level of trust in IJVs in these countries will be evaluated. A framework has been developed based on this review analyses and integrates empirical evidence in order to identify convergence and conflict in IJV. The paper addresses a problem of relevance to both international academics and practitioners in addressing managerial implications. It is hoped that the study will provide a meaningful implication to the process of selection of IJV partners
How journal rankings can suppress interdisciplinary research. A comparison between Innovation Studies and Business & Management
This study provides quantitative evidence on how the use of journal rankings
can disadvantage interdisciplinary research in research evaluations. Using
publication and citation data, it compares the degree of interdisciplinarity
and the research performance of a number of Innovation Studies units with that
of leading Business & Management schools in the UK. On the basis of various
mappings and metrics, this study shows that: (i) Innovation Studies units are
consistently more interdisciplinary in their research than Business &
Management schools; (ii) the top journals in the Association of Business
Schools' rankings span a less diverse set of disciplines than lower-ranked
journals; (iii) this results in a more favourable assessment of the performance
of Business & Management schools, which are more disciplinary-focused. This
citation-based analysis challenges the journal ranking-based assessment. In
short, the investigation illustrates how ostensibly 'excellence-based' journal
rankings exhibit a systematic bias in favour of mono-disciplinary research. The
paper concludes with a discussion of implications of these phenomena, in
particular how the bias is likely to affect negatively the evaluation and
associated financial resourcing of interdisciplinary research organisations,
and may result in researchers becoming more compliant with disciplinary
authority over time.Comment: 41 pages, 10 figure
Explaining the Diversification Path of Exporters in Brazil: How Similar and Sophisticated are New Products?
A stylised fact of the economic literature suggests that export diversification is good for economic growth and is associated with economic development. In addition, there is evidence suggesting that the level of sophistication of countriesâ exports âmattersâ for growth and development. This paper contributes to this literature by analysing two unexplored dimensions of export diversification: the degree of relatedness (similarity) and sophistication of new products in relation to existing ones. The objective of this paper is to understand the mechanisms through which firms are able to diversify to less related and more sophisticated activities. We do so using a unique dataset that links data on exports, innovation and firmsâ characteristics at the firm level in Brazil. The main findings suggest that i) diversification occurs in very closely related activities, where firms have some core competences, ii) most diversification occurs in new products with lower level of sophistication than existing exports, iii) the degree of diversification and innovativeness of the production basket, and the position that the firm has developed in the domestic market appear to matter for diversification towards more or less distant products.Diversification; Relatedness; Sophistication; Trade; Innovation; Brazil
Prediction of Emerging Technologies Based on Analysis of the U.S. Patent Citation Network
The network of patents connected by citations is an evolving graph, which
provides a representation of the innovation process. A patent citing another
implies that the cited patent reflects a piece of previously existing knowledge
that the citing patent builds upon. A methodology presented here (i) identifies
actual clusters of patents: i.e. technological branches, and (ii) gives
predictions about the temporal changes of the structure of the clusters. A
predictor, called the {citation vector}, is defined for characterizing
technological development to show how a patent cited by other patents belongs
to various industrial fields. The clustering technique adopted is able to
detect the new emerging recombinations, and predicts emerging new technology
clusters. The predictive ability of our new method is illustrated on the
example of USPTO subcategory 11, Agriculture, Food, Textiles. A cluster of
patents is determined based on citation data up to 1991, which shows
significant overlap of the class 442 formed at the beginning of 1997. These new
tools of predictive analytics could support policy decision making processes in
science and technology, and help formulate recommendations for action
Connected innovation: an international comparative study that identifies mixed modes of innovation
This paper offers a new angle on innovation modalities by adopting a recently emerging approach towards identifying innovation typologies via exploratory data analysis techniques with the aim to tease out some underlying latent variables that represent coherent innovation strategies for groups of firms. Mixed modes of innovation include aspects of both user and open innovation, and are employed to inform on such concepts. The modes of innovation are developed by exploring micro-level innovation survey data across 18 countries. The contributions of the paper lie in (a) the identification of five core innovation modes that are found in almost all countries; and (b) examining â via regression analysis â the role of different modes in firm performance
