    Un approccio di teoria del caos all'analisi delle serie storiche economiche

    No full text
    Nella teoria del caos lo studio delle serie storiche economiche è stato effettuato utilizzando per lo più gli strumenti metrico- dinamici. Questi studi hanno dato risultati ambigui sottolineando la presenza di insolite strutture non-lineari. La difficoltà di una loro applicazione alle serie brevi può essere indicata come la maggior causa del rifiuto di caos deterministico. L’obiettivo è quello di superare le limitazioni dell’approccio metrico analizzando i dati del GDP di Giappone e Inghilterra con uno strumento topologico: VRA. Le conclusioni raggiunte implicano il superamento dei risultati ottenuti sottoponendo gli stessi dati ad analisi metrico-dinamica evidenziando le potenzialità dell’approccio topologico in economia

    Chaos and Chaotic Dynamics in Economics

    No full text
    Proponents of chaos theory attempted to articulate a new, more realistic, scientific world-view contradictory to the fundamental notions of the Newtonian view of science. Nonlinearity and chaos give the opportunity of a reconciliation of economics with a more realistic representation of its phenomena. Chaos theory represents a means for enhancing both the methodological and theoretical foundations for exploring the complexity of economic phenomena. This paper offers an overview of the applications of chaos theory in economics highlighting that recognizing the existence of deterministic chaos in economics is important from both a theoretical and practical point of view

    Knowledge Technology Transfer: A Spatial Analysis within the Triad

    No full text
    The aim of this study is that of further exploring the knowledge spillover effects of Large International firms. In particular, we implement a spatial analysis in United States, Japan and Europe. We use technological vectors of firms to compute Jaffe proximity measure in such a way that we get knowledge externalities relative to different countries. To our end, we estimate the spatial-autoregressive model where we consider also additional endogenous variables. The findings demonstrate the significant positive effect predicted by the core literature about this topic
