The purpose of this paper is to investigate the impact of heterogeneous beliefs about market demand on the profitability of firms under different competitive settings. To this end I consider a differentiated duopoly model where two firms with different beliefs about the market demand can compete in quantity (Cournot competition) or in price (Bertrand competition). The results show that the optimistic firm can outperform the pessimistic firm in profits under Cournot competition even in the state of Low demand as long as the ratio of High demand over Low demand is sufficiently low. Under Bertrand competition, however, if the ratio of High demand over Low demand is sufficiently low or the overall optimism of the two firms is sufficiently high, the pessimistic firm can gain higher profit than the optimistic one even when demand is high.  相似文献

The majority of research to date investigating strategic tariffs in the presence of multinationals finds a knife-edge result where, in equilibrium, all foreign firms are either multinationals or exporters. Utilizing a model of heterogeneous firms, we find equilibria in which both pure exporters and multinationals coexist. We utilize this model to study the case of endogenously chosen tariffs. As is standard, Nash equilibrium tariffs are higher than the socially optimal tariffs. Unlike existing models with homogeneous firms, we find that non-cooperative tariffs promote the existence of low-productivity firms relative to the socially optimal tariffs. This highlights a new source of inefficiency from tariff competition not found in models of homogeneous firms. In addition, we find that in many cases the Nash equilibrium tariff when FDI is a potential firm structure is lower than when it is not. As a result, FDI improves welfare by mitigating tariff competition.  相似文献

The Australian economy has performed well compared with comparable countries over the last three decades only if we average the excellent performance in the 1990s and the poor performance over the past decade. Real wages over the past decade have stagnated—to an extent without historical parallel. We cannot understand the economy's underperformance without recognising the increasing claims of economic rents on national income. Correction of weaknesses requires coordination of many policy instruments including measures to reduce the prevalence of rents (competition policy and regulation of oligopoly where competition is not feasible or inefficient) and changes in taxation arrangements to shift the burden of business taxation from firms in competitive activities to firms relying heavily on economic rents.  相似文献

In 1885, the largest churches in Scotland were engaged in a dispute about state funding. We use data generated in the course of that dispute to test two related hypotheses. First, as market size (proxied by population) increases, the competitiveness (or complexity) of the religious market structure will not decrease. Second, religious activity, as measured by giving per member, church income and participation, will not decrease as market competitiveness (or complexity) increases. Empirical evidence lends support to the first hypothesis, but casts doubt on the second, and the supply-side theories underpinning it, which posit a causal link between increased competitiveness (complexity) and higher levels of religious activity. In interpreting the results the importance of a rich understanding of institutional arrangements—particularly market structure, governance and financing—is underlined.  相似文献

We demonstrate that the common view according to which an increase in competition leads banks to increased risk taking fails to hold in an environment where homogeneous loss averse consumers can choose in which bank to make a deposit based on their knowledge of the riskiness incorporated in the banks outstanding loan portfolios. With an exclusive focus on imperfect competition we find that banks incentives for risk taking are invariant to a change in the banking market structure from duopoly to monopoly. Finally, we show that deposit insurance would eliminate the gains from bank competition when banks use asset quality as a strategic instrument.revised version received October 15, 2003  相似文献

This article studies how store format choices and market concentration affect agglomeration economies and competition among chain stores. Using data on supermarket chains in Arizona, Georgia and Illinois, we decompose a store’s sales into parts stemming from local market conditions, such as demographics, and parts stemming from competition measures, which can be of its own chain’s stores or of other chains’ stores. Our results show that local market conditions are still a key factor in generating store sales. In more concentrated markets of Georgia and Illinois, a supermarket chain suffers from business-stealing among its own stores – agglomeration economies not sufficient to offset competition among its stores – but ironically tolerates the presence of other chains’ stores. Can a retail chain favourably tip the balance of agglomeration economies and competition? We find the answer by looking at the two big corporations in Arizona – Bashas Markets Inc. and Kroger Co. – which own two and three store formats, respectively, catering to distinct consumer segments, and thus promoting agglomeration economies while minimizing competition among their own stores.  相似文献
