This paper empirically explores relations between network positions in knowledge networks andtrust. In social network … theory the closure argument and the gossip argument describe thisrelation. These two arguments do not distinguish between …-specific knowledge networks. Empirical data were collected on a network of 55 individuals inthe setting of account management. These data …

Knowledge drives the growth of nations and regions in a competitive space-economy. Hence, we would expect a strong … correlation between investments in R&D, knowledge and learning processes, on the one hand, and productivity increases, on the … other. However, the empirical evidence shows consistent discrepancies between knowledge inputs and economic performance …

In this paper we study Markov Decision Process (MDP) problems with the restriction that at decision epochs only a … finite number of given Markovian decision rules may be applied. The elements of the finite set of allowed decision rules … should be mixed to improve the performance. The set of allowed Markovian decision rules could for example consist of some …

In this paper methods of mixing decision rules are investigated and applied to the so-called multiple job type … assignment problem with specialized servers which is modeled as continuous time Markov decision process. Performance optimization … the described mixing methods a suitable static decision rule is mixed with some dynamic decision rules which are easy to …

We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge … exchange. Growth is generated through human capital accumulation and knowledge externalities. The available knowledge in any … knowledge with. We show how the diffusion of knowledge through the world explains the evolution of global income inequality. It …
