  • On the Change of Periodicities in the Hicksian Multiplier-Accelerator Model with a Consumption Floor
  • 2006

    • The Hicksian multiplier-accelerator model with “floor” and “ceiling” continues to be the most successful machine generating business cycles. This is, no doubt, due to its capability of explaining both downturn and upswing through one single model. The “ceiling” is due to a full employment constraint, whereas the “floor” is due to a limit to disinvestment when no worn out capital at all is replaced. However, another “floor” to consumption at zero level seems never to have been discussed. Hence, net disinvestments, even if they are bounded downwards, may also give rise to negative consumption, which is absurd. As we will show, the effect of an additional constraint to avoid this is easy to analyze, and results in a change of the periodicities according to a simple rule.

  • On the Genesis of Hexagonal Shapes
  • 2004
  • Reports (other academic/artistic)abstract
    • Hexagonal shapes for market areas have been dominant in spatial economics ever since Christaller observed them and Lösch explained their emergence in terms of optimality. It is observed in the following that, though hexagons are best, the differences to for instance squares in terms of efficiency are negligibly small. As the existence of hexagonal shapes - in the space economy, as well as in beehives or other patterns of the physical world cannot be denied - a different cause for their emergence is proposed. Such an explanation is structural stability, which allows three market areas, but not four or six, to come together in each common vertex. The focus is hence the way market areas are organized in space, rather than their shape.
