What do we [not] know about technology entrepreneurship research?

This study aims to review what we do (and do not) know about technology entrepreneurship (TE) research to date. Based on a categorized bibliometric analysis resulting from a systematic review of 135 scientific articles published in refereed journals over the past 27 years (1986–2013), we identify the core domains of TE, its intellectual structure, the scientific journals with a major impact in this field of research, and the affiliation and collaboration networks within it. Specifically, through a detailed analysis of article co-citations within the TE area, this study provides co-citation networks of authors, journals, and their respective clusters, revealing their rankings in terms of contributions to the TE literature. This comprehensive analysis can be used to enhance our understanding of TE and support further research in this field.     

MLP ensembles improve long term prediction accuracy over single networks

This work describes an award winning approach for solving the NN3 Forecasting Competition problem, focusing on the sound experimental validation of its main innovative feature. The NN3 forecasting task consisted of predicting 18 future values of 111 short monthly time series. The main feature of the approach was the use of the median for combining the forecasts of an ensemble of 15 MLPs to predict each time series. Experimental comparison to a single MLP shows that the ensemble increases the performance accuracy for multiple-step ahead forecasting. This system performed well on the withheld data, having finished as the second best solution of the competition with an SMAPE of 16.17%.     

Corporate social responsibility,country-level predispositions,and the consequences of choosing a level of disclosure

We study the different levels of corporate social responsibility (CSR) disclosures of the largest European firms. We find that firms are more predisposed to disclose more CSR information in countries with better investor protection, higher levels of democracy, more effective government services, higher quality regulations, more press freedom, and a lower commitment to environmental policies. Our analysis of the association of different levels of CSR disclosure with share prices indicates that a high level of CSR disclosure is associated with higher share prices, whereas a low level of CSR disclosure in sensitive industries is associated with lower share prices (compared to no disclosure). These results are also present when we analyse changes in CSR disclosure and are robust to the inclusion of an accounting quality measure in our model. The overall effect of the association of higher levels of CSR disclosure with higher share prices is stronger in countries with more democracy, more government effectiveness, better regulatory quality, and more press freedom. Therefore, market participants find CSR disclosures more informative in countries where investors are in a better position to voice their concerns and where there is better regulation and more effective government implementation of regulations.

Enhancing individual entrepreneurial orientation measurement using a metacognitive decision making-based framework

Entrepreneurship, and individuals’ predisposition toward entrepreneurial activities in particular, i.e. Individual Entrepreneurial Orientation (IEO), has been gaining increasing relevance in academia and management practice alike. Understanding IEO is a critical element not only for its promotion, but for better and more informed managerial and investor decision making as well. As such, this study proposes a new framework for understanding and measuring IEO based on the integrated use of cognitive mapping and the interactive multiple criteria decision making (TODIM) method. We present the steps for building such a framework, as well as a practical application of these steps. The results are promising: the methodology applied allowed a large number of determinants of IEO and their relationships to be mapped; and, subsequently, ranked and weighted for the creation of an IEO measurement tool. The implications of the resulting framework for theory and practice, its limitations and possibilities for further research are also discussed.

Trustee reputation in securitization: When does it matter?

We consider the role of trustees–who are nominated to protect the interests of investors–in securitization pricing and whether investors rely on them to mitigate risks. In particular, we examine the effect of trustee reputation on initial yield spreads of European mortgage‐backed security (MBS) issuances between 1999 and the first half of 2007. We find that engaging reputable trustees led to lower spreads during the credit boom period prior to the 2007–2009 financial crisis. Our findings suggest that trustees’ reputation was considered by investors to be more important when risk assessment became more challenging.
