The presence of multiple sellers in the provision of (non-substitutable) complementary goods leads to outcomes that are worse than those generated by an integrated monopoly, a problem also known as the «tragedy of the anticommons». In this paper we identify some conditions under which the...

We consider the combine use of environmental taxation and technological standards of abatement. While it is not necessary to regulate technology adoption under complete information, we show that the environmental agency has to impose a technological standard when monitoring emissions is costly...

This paper suggests a model of the process through which a set of symbols, initially without any intrinsic meaning, acquires endogenously a conventional and socially shared meaning. This model has two related aspects. The first is the cognitive aspect, represented by the process through which...

This paper shows the relevance of Popper's Rationality Principle (RP) for the appraisal of the impressive mass work emerging, in recent years, in the fields of rationality, learning, evolutionary games and behavioral economic theory. In contradistinction to the well-known rigid criteria of the...

Production sharing contracts are one of the most popular forms of contractual system used in petroleum agreements around the world, but the manner in which the fiscal terms and contract parameters impact system measures is complicated and not well understood. The purpose of this paper is to...

Fundamentals of two different numerical approaches to the fluid flow modelling are presented. The smoothed particle hydrodynamics (SPH) is a meshless approach, while the finite volume (FV) method is defined on a grid. Within SPH, the computational grid is replaced by a finite set of...

The diffusion of energy saving technologies is an important part of UK energy and climate policy. Innovation diffusion can be influenced by both technological and behavioural factors. A computational model is presented to capture how changing technology attributes can influence consumer...

We develop a model that captures the basic characteristics of competitively authoritarian regimes. An incumbent (government) faces a challenge from a rival (opposition). There is also an agent (bureaucracy) who can shirk and can interfere in this contest. Shirking is costly to the incumbent. The...
