    Examining the Relationship Between Organizational Ambidexterity and Firm Performance in New Technology-Based Firms
    (Multidisciplinary Digital Publishing Institute (MDPI), 2026-03-01)
    Organizational ambidexterity is an essential topic in management research. A growing number of studies argue that organizational ambidexterity is increasingly critical to the sustained competitive advantage of firms. However, there is less research on ambidexterity in new technology-based firms, despite the significant impact it has on local and national economies. The study examined the relationship between organizational ambidexterity and firm performance (non-economic and economic). The sample consists of 102 Colombian new technology-based firms. A latent variable design or structural equation modeling was followed. The statistical method was Partial Least Squares Structural Equation Modelling (PLS-SEM). According to the results, organizational ambidexterity is positively related to both non-economic and economic performance. Organizational ambidexterity explained 10% of the variance of the economic performance and 56% of the variance of the non-economic performance. These findings highlight the importance of organizational ambidexterity to obtain better firm performance, especially non-economic performance related to customer perception, employee satisfaction, and improvement in the quality of products and services in new technology-based firms.

    A Bibliometric Analysis on Network-Based Systemic Risk
    (Multidisciplinary Digital Publishing Institute (MDPI), 2025-11-01)
    The vulnerability of the global financial system to systemic risk-related adverse events has become more evident in recent years, as shown by the 2008 financial crisis and the global pandemic. This study examines systemic risk and its contributing factors using network analysis to understand how contagion occurs. To achieve this, a bibliometric analysis was conducted using a cluster analysis of publications from 2020 to 2025. The bibliometric analysis covered 1642 papers related to systemic risk and financial transmission networks. The CiteSpace software was used to identify seven thematic clusters. The results show the relevance of topological analysis in explaining the connection between institutions and the spread of risk. There is also a clear tradition in the literature of applying the DY spillover index, which captures the temporal dynamics of systemic connectivity. Multilayer networks stand out as a trend in recent studies, as they have the potential to represent different types of relationships simultaneously between nodes. Finally, the literature pays attention to systemic connectivity problems during crises, which can amplify volatility and generate forced asset sales, highlighting the need to use advanced VAR-type models to anticipate risk transmission and guide macroprudential management.
