Comparative statics, strategic complements and substitutes in oligopolies

Article Abstract:

The first- and second-order monotonicity properties with regard to the equilibrium prices, quantities, profit margins and profits for oligopoly models are established with general non-linear cost functions and general dependencies of the cost and demand functions on the strategic input parameters under consideration. An attempt is made to unify isolated monotonicity results in oligopoly models arising in public finance.

Qualitative comparative statics

Article Abstract:

A qualitative approach applied to the comparative statics analysis of purely quantitative models and models maximizing agents has a number of limitations as evidenced by necessary and sufficient conditions needed for both full and partial sign solvability. Hicksian stability is also identified through the study of qualitative partial equilibrium models using the stability hypothesis.
