Two monopolists operate in two countries which differ only for their per capita income. Each firm sells a single product which is vertically differentiated. If trade opens, the firm operating in the poorer country starts to export to the richer. This might induce the government of the richer...

The behaviour of labor managed and profit seeking firms in a Cournot duopoly with capital strategic interaction is analysed. Whena pure labor managed duopoly is considered, firms choose their capital commitments according to the level of the interest rate, unlike what usually happens when only...

Different market settings are considered in a free trade environment, where firms can choose technology, quality, and price or quantity. The shape of competition in prices requires the intervention of governments, via a common antidumping policy, to make firms converge on the simultaneous...

We analyse sequential entry in a quantity-setting oligopoly model. Firms have the option to adopt either a productive capacity which is optimal at the time of entry or a smaller one. This capacity may be suitable either for the steady state or just some time after entry. In the latter case firms...

We analyse R&D activity in transport and communication technology (TCRD), in a Cournot duopoly. Transport and communication costs are of the iceberg type, i.e., using up some portion of the product along its path to the final buyer. Firms invest in TCRD to increase the net amount of the product...

The paper contains first the analysis of the strategic decision as to whether to integrate or not, in a market with differenciation of final products feeding back into the production of intermediate inputs. Cournot competition makes integration a dominant strategy, althogh it is not Pareto...

According to received literature, vertical integration may enjoy a social superiority due to the ability to internalize the externality that goes back from the pricing policy of the downstream firm to the profits of the upstream firm. We challenge this result introducing process R&D in a broad...

We reassess the respective gains from R&D cooperation and competition in a Cournot Duopoly with homogeneous goods, where firms adopt a concave cost-reducing R&D technology. Contrary to the previous literature on the same topic, our main results are that (i) no corner solutions emerge and (ii)...
