This paper attributes the slow diffusion of innovations to an informational externality in the process of their adoption. When a new technology arrives its profitability is uncertain but each firm can learn progressively through observing the adoption experience of other firms. Given this prospect of social learning, every firm would prefer that other firms adopt before it does because this ena...

This paper investigates the impact of geography on technological diffusion via international trade and proposes to re-examine the contribution of Coe, Helpman and Hoffmaister to the knowledge spillovers literature. Using a gravitational model, we first confirm the negative effect of physical distance on imports. We also show that geographic proximity contributes to more technological diffusion ...

This paper proposes a generic framework for analyzing innovation systems, anchored around five fundamental activities — R&D, implementation, end-use, education, linkage — and focused on the performance implications of a system’s structure and dynamics. Rather than simply describing the role and performance of particular actors, institutions and policies, this approach focuses on system-level ch...

A discursive approach to technological innovation recognises that scientific and technical innovations are the products of groups of people. The subject of this paper is how this insight from the sociology of scientific knowledge can make a contribution to debates in economic geography. Principally drawing on the work of social constructionists, this approach is used to provide insights into th...

Davies’ method of perturbed semigroups is a classical technique to obtain off-diagonal upper bounds on the heat kernel. However Davies’ method does not apply to anomalous diffusions due to the singularity of energy measures. In this note, we overcome the difficulty by modifying the Davies’ perturbation method to obtain sub-Gaussian upper bounds on the heat kernel. Our computations closely follo...

Despite the wideness of the literature on technological innovation, the diffusion of the supply chain collaborative technology innovation has not still received much attention. This paper is an attempt to answer the question that how the supply chain collaborative technological innovations emerge and diffuse. An agent-based model of collaborative supply chain technological innovation including ...
