Price competition in a differentiated products duopoly under network effects

We examine price competition under product-specific network effects, in a duopoly where the products are differentiated both horizontally and vertically. We emphasize the role of consumers’ expectations formation. When expectations are not influenced by prices, the market may be shared but shares must be equal unless product qualities differ or one firm, possibly even the low-quality one, may capture the entire market. When expectations are influenced by prices, which would be the case when there is commitment, competition becomes more intense and the high-quality firm tends to capture a larger market share. Under strong network effects there is a continuum of equilibria and the higher the prices, the smaller the difference between those prices can be. Requiring continuity of expectations, however, delivers a unique equilibrium where one firm captures the entire market.     

Strategic tariffs, tariff jumping, and heterogeneous firms

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.     

香港和内地证券市场的动态竞争关系研究——基于A+H交叉上市公司的实证分析

交叉上市引起不同证券市场对有限投资者和资金资源的竞争。文章在阐述证券市场竞争的Lotka-Volterra模型基础上,通过2006-2010年38家A+H交叉上市企业的日交易数据实证分析了香港和内地证券市场之间的动态竞争过程。结果表明,两市场之间的动态竞争关系从交叉上市初期的捕食—诱饵关系逐步演化为目前的竞争互惠关系,且这种动态演化过程与企业交叉上市顺序没有显著的相关性。这说明内地证券市场正在不断完善,鼓励企业境外上市和A股回归将有利于内地证券市场的发展,而且互惠合作应是未来证券市场竞争的发展趋势。     

城市群竞合问题研究

近年来,我国城市群发展迅速,但竞合水平较低。从总体来看,我国城市群竞合主要存在竞合意识缺乏、竞争多于合作、形式大于实效、重硬件轻软件等问题。要提升我国城市群的竞合水平,必须加强竞合制度的建设,改善软环境及参与国际竞合,使竞争与合作相互促进,推动城市群经济健康发展。

发达省域战略性新兴产业竞争研究

战略性新兴产业可分为强环境驱动型与弱环境驱动型、准先导型与准支柱型。在对各新兴产业作全国性比较的基础上,发现发达省域可兼顾比较优势、竞争优势与不确定性的要求来优化产业定位。发达省域遭遇世界长波衰退、世界能源危机、中国亚军危机、房地产泡沫、冲动性投资、低劳动收入等环境因素对新兴产业形成的内外"双轮夹击"。构建"软硬双驱"竞争优势模型,并由此指出发达省域战略性新兴产业竞争优势升级的路径。
