Transition from the planned to the market economy involved profound changes in Ukrainian economy. Before the liberalization of prices in 1992, milk processing in Ukraine was concentrated in regionally distributed large state milk processing factories. In the meantime, the dairy sector has been...

We derive several comparative-static results for Cournot games when firms have nonconstant marginal-cost curves which shift exogenously. The results permit us to rank certain vectors of equilibrium marginal costs with the same component sum according to their associated social surplus or...

In this paper we classify competitive markets using a new form of normalized Herfindahl index and the degree of dominance of the leader. For this purpose we use the notion of copula, which connects two or more random variables with given marginals. The parameters of the two marginals (which are...

Having in mind inequalities we can also discuss concentration issues, and the concentration itself is a problem to which the author refers on first place. The paper is organized as...

In this paper we attempt to make a compilation of several concentration and stability indexes used in the literature since 1945, showing that while the Hirschman-Herfindahl index and concentration ratio are most commonly used, there are also alternative measures. Likewise, we present two...
