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 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...

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...

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...

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...
