The paper moves a step forward in the direction of establishing a connection between the structure and evolution of knowledge
bases and the structure and evolution of organizational forms in innovative activities in a science-intensive industry. The
paper has an explicit focus on the dynamics of the network of collaborative agreements in R&D in the pharma/biotech industry
after the “molecular biology revolution”. Using a comprehensive dataset, built by the authors integrating several sources
in the industry, the dynamics of the network over time is extensively analyzed. With regards to network structure, it is found
that, while the size of the network increases over time due to net flows of entry, its topological properties remain relatively
unchanged. The evolution of the network has occurred without relevant deformations in the core-periphery profile. With regards
to age-dependent propensity to collaborate, the paper finds that the extent of inter-generational collaboration is much more
significant than intra-generational collaboration. In addition, the propensity of firms of a given generation to enter into
collaboration with firms of a different generation increases with the distance between the two, while the total number of
intra-generational collaborations decreases over time and, moreover, tends to decrease for most recent generations. In the
paper a unitary and coherent explanation of the evidence is developed, coming to reveal the existence of a striking isomorphism
between structural properties of the dynamics of knowledge and of the evolution of network structure.

This paper presents evidence that corporate governance quality measured by (1) the board size and (2) the fraction of directors
that serve on more corporate boards, influences the market value of firms. The analysis is based in Italy, a country that
is characterized by family and concentrated ownership, low legal protection of investors and pyramidal firm structures. Our
empirical results suggest that the level of ‘busy-ness’ of corporate directors as a measure of board effectiveness has a significant
influence on firm’s market performance. By contrast, we find limited evidence that board size has a substantial impact on
the market valuation, except in small and medium enterprises and in some specific industry sectors.

Multi-regional input–output (I/O) matrices provide the networks of within- and cross-country economic relations. In the context of I/O analysis, the methodology adopted by national statistical offices in data collection raises the issue of obtaining reliable data in a timely fashion and it makes the reconstruction of (parts of) the I/O matrices of particular interest. In this work, we propose a method combining hierarchical clustering and matrix completion with a LASSO-like nuclear norm penalty, to predict missing entries of a partially unknown I/O matrix. Through analyses based on both real-world and synthetic I/O matrices, we study the effectiveness of the proposed method to predict missing values from both previous years data and current data related to countries similar to the one for which current data are obscured. To show the usefulness of our method, an application based on World Input–Output Database (WIOD) tables—which are an example of industry-by-industry I/O tables—is provided. Strong similarities in structure between WIOD and other I/O tables are also found, which make the proposed approach easily generalizable to them.
