We consider a Cournot Oligopoly market of firms possessing increasing returns to scale technologies. It is shown that an external regulating agency can increase total social welfare without running a deficit. It offers to subsidize one firm an amount which depends on the output level of that...

This paper provides a novel rationale for the regulation of market size when heterogeneous firms compete. A regulator seeks to maximize total welfare by choosing the number of firms allowed to enter the market, e.g. by issuing a certain number of licenses. Opening up the market for more firms...

We consider a Cournot oligopoly market of firms possessing increasing returns to scale technologies (which may not be identical). It is shown that an external regulating agency can increase total social welfare without running a deficit by of ering to subsidize one firm an amount which depends...

We study a dominant firm Cournot oligopoly, with one low-cost firm and one or more high-cost firms. If equilibrium is interior, with all firms producing positive quantity, a reallocation of production relative to the equilibrium point, such that the low-cost firm produces more, while the...

In an industry where firms compete via supply functions, the set of equilibrium outcomes is large. If decreasing supply functions are ruled out, this set is reduced significantly, but remains large. Specifically, the set of prices that can be sustained by supply function equilibria is the...

Whereas in the absence of capacity constraints the Cournot outcome is the unique coalition-proof supply function equilibrium outcome, the presence of capacity constraints may enlarge the set of equilibrium outcomes. Interestingly, if capacities are sufficiently asymmetric the new equilibrium...

Australia's comparatively small and open economy is subject to boom-bust shocks that centre on its exporting mining and agricultural industries which, in average years, are minor contributors to its GDP. The associated real exchange rate effects, however, have important implications for overall...

Progress has been made in economic reform under the “Abenomics” first (monetary policy) and second (taxation reform) “arrows”. The third, which emphasises structural reforms, has been more politically difficult, thus far yielding mixed results. This paper explores the gains that are...

We determine the emergence of the Porter Hypothesis in a large oligopoly setting where the industry-wide adoption of green technologies is endogenously determined as a result of competition among coalitions. We examine a setting where the initial technology is polluting, firms decide whether to...

While models of mixed oligopoly have been analyzed within a rapidly growing literature, little is known about the mechanism of efficiency improvement relating to partial privatization. In this paper, we endogenize efficiency improvement in relation to the level of privatization. We show that in...
