This paper applies the methodological tools typical of social network analysis (SNA) within an evolutionary framework, to investigate the knowledge-base (KB) dynamics of the biotechnology sector. Knowledge is here considered a collective good represented as a co-relational and a...

<Para ID="Par1">We extend a result of Dubins (Ann Probab 3:89–99, <CitationRef CitationID="CR8">1975</CitationRef>) from bounded to unbounded random variables. Dubins showed that a finitely additive expectation over the collection of bounded random variables can be written as an integral of conditional expectations (disintegrability) if and only if the...</citationref></para>

<Para ID="Par1">Starting from a likelihood function and a prior information represented by a belief function, a closed form expression is provided for the lower envelope of the set of all the possible “posterior probabilities” in finite spaces. The same problem, removing the hypothesis of finiteness for the...</para>

We revisit a central task of the extant liquidity literature, which is to identify effective measures of liquidity. We critically assess the influential practice of identifying the best liquidity measures based on monthly correlations by comparing and contrasting correlations between monthly and...
