We provide an extensive and general investigation of the effects on industryperformance - profits, social welfare and price-cost margins - of exogenously changing the number of firms in Cournot markets. This includes an in-depth exploration of the well-known trade-off between competition and...

We examine sales and leasing of a durable good in an asymmetric duopoly. We find that inefficient firms tend to lease more. While the low cost firm sells more than the high cost firm, the high cost firm leases more. Further, an increase in unit costs implies a higher ratio of leased units to...

We investigate consequences of a situation in which a merged subgroup of firms leads the market, after which merger experiences reduced marginal cost. Results show that while introduction of higher cost synergy to the model increases firms' motive to merge, it may not necessarily mitigate...

We present examples of cost-asymmetric duopoly games where the inefficient firm can obtain higher payoff than its efficient rival. Firms compete in a Cournot fashion and their quantities are chosen by their managers. We assume that managers are offered two types of incentive contracts, the pure...

We stress some efficiency aspects of monopolistic competition justifying it on account of its tendency to innovate and the questionable excess capacity paradigm. Some further efficiency aspects revealed are product variety and transaction cost savings. We view the monopolistically competitive...
