The relationship between the size and the variance of firm growth rates is known to follow an approximate power-law behavior σ(S) similar to S^-β(S) where S is the firm size and β(S) almost equal to 0.2 is an exponent weakly dependent on S. Here we show how a model of proportional growth...

The prominent role played by patents within the pharmaceutical domain is unquestionable. In this paper we take an unusual perspective and focus on a relatively neglected implication of patents: the effect of patent-induced information disclosure (of both successes and failures) on the dynamics...

Applied research on growth and innovation seems to suggest that successful innovations do not significantly enhance firm growth. This paper tests the hypothesis that the level of observation at which applied research is typically conducted hampers identification of a significant association...

We study the structure of business firm networks in the Life Sciences (LS) and the Information and Communication Technology (ICT) sectors. We analyze business firm networks and scale-free models with degree distribution P(q) proportional to (q + c)^-λ using the method of k-shell decomposition....

In this paper we propose a model of bounded rational organizations that addresses the role of organizational capabilities in shaping firm size, growth rates and profitability. Our approach aims at reconciling the logic behind stochastic models of firm growth with the notion of organizational...

Il miglioramento qualitativo dei prodotti e di servizi alla clientela sono stati individuati, da una vasta letteratura sul tema, quali fattori determinanti per un riposizionamento di mercato. Inoltre, la necessità di un sostegno pubblico ad innovazioni che agiscano sulla qualità (effettiva o...

This paper addresses a debated issue in the economics innovation literature, namely the existence of increasing return to R&D expenditures and sirm size on innovation output. It further explores how structural characteristics of the sirm as well as contextual factors affect the dynamics of...

The idea of preference reversal and construction of preference is not new to literature in decision making. Indeed, several theories have been developed to explain it. (Lichtenstein and Slovic, 2006). The present paper considers heuristics activated in different elicitation procedures applied in...

Despite the rich and interdisciplinary debate on the role of diversity and communication in group problem solving, as well as the recognition of the interactions between the two issues, they have been rarely treated as a joint research topic. In this paper we offer a computational model of...

To introduce new products and processes, firms often need to acquire knowledge developed in other firms and organizations. Drawing on social capital and transaction cost theory, we argue that not only is the success of such acquisitions for the development of product and product innovations...
