Competitive Industry Dynamics with Constant Costs
This paper integrates investment and production decisions in a dynamic model of a competitive industry where producers, facing a technology involving fixed input–output coefficients, employ quantity adjustment rules. Whether complex dynamic price behaviour is consistent with producers breaking-even over time is explored. The proportion of costs which are sunk through investment is shown to have a potentially dramatic impact on the price dynamics. The implications of an alternative hypothesis— that producers ‘normally’ use their avail able capacities and only do otherwise if events are sufficiently dramatic—are explored
Labour supply with habit formation
Abstract In a model with habit-forming labour supply we show that standard myopic utility maximisation of a person weakly addicted to a harmful habit is consistent with empirical results on labour supply.
Non-linearities and partial analysis
Abstract This paper argues that, where there are non-linearities, the fundamental postulate of partial analysis — the principle of the negligibility of indirect effects — may be undermined: any feedback effects, however seemingly negligible, may have profound implications.
