We study diffusion of information packets on several classes of structured networks. Packets diffuse from a randomly chosen node to a specified destination in the network. As local transport rules we consider random diffusion and an improved local search method. Numerical simulations are...

Recently the thermostatted kinetic framework has been proposed as mathematical model for studying nonequilibrium complex systems constrained to keep constant the total energy. The time evolution of the distribution function of the system is described by a nonlinear partial integro-differential...

How can firms extract value from already-implemented information technologies (IT) that support the work processes of employees? One approach is to stimulate employees to engage in post-adoptive extended use, i.e., to learn and apply more of the available functions of the implemented...

There is widespread concern among regulators that favoring suppliers with good past performance, a standard practice in private procurement, may hinder entry by new firms in public procurement markets. In this paper we report results from a laboratory experiment exploring the relationship...

Massive intra-Asian economic integration has been accompanied by very little institution building. This paper considers whether Asia needs new institutions by drawing lessons from the EU’s supranational integration sequence and EFTA’s intergovernmental sequence. Sequencing theory is...

The nature of energy and material resources in an endogenous growth theory framework is clarified. This involves three modifications of the conventional theory. Firstly, multiple feedback mechanisms or “growth engines” are identified. Secondly, a production function distinguishes between...

This paper reports results from a laboratory experiment exploring the relationship between reputation and entry in procurement. There is widespread concern among regulators that favoring suppliers with good past performance, a standard practice in private procurement, may hinder entry by new...

This paper reports results from a laboratory experiment exploring the relationship between reputation and entry in procurement. We propose a procurement model with reputation and entry assigning to the entrant a reputational advantage of varying size across treatments. There is widespread...

One of the key points addressed by Per Bak in his models of brain function was that biological neural systems must be able not just to learn, but also to adapt—to quickly change their behaviour in response to a changing environment. I discuss this in the context of various simple learning...
