产业转移的新经济地理学解释

不同于传统的产业转移理论,新经济地理学在规模报酬和垄断竞争框架下解释了产业转移现象,认为产业转移的基础不必然是第一自然的差异,在完全相同的均质空间下,由于市场接近效应、生活成本效应和市场拥挤效应所构成的集聚力和扩散力的相互作用,产业转移也会发生,并且表现出突发性、自我强化、预期自我实现和价值链环节分离的特性及关联度弱的产业先转移等规律。此外,新经济地理学还运用一般均衡分析方法考察了产业转移的福利效应,包括瓦尔拉斯效应、生产租金和规模区位效应、累积效应以及转移效应,并对影响产业转移的税收优惠竞争、公共基础设施改善和区域补贴等政策措施的效果进行了剖析。     

National culture, networks and ethnic entrepreneurship: A comparison of the Indian and Chinese immigrants in the US

This paper uses a combination of national cultural frameworks and social capital theory to explain the formation and management of entrepreneurial ventures among immigrant communities. The varying rates of venture formation and performance among different ethnic groups points to the role that the different dimensions of culture play in how immigrants use their social networks to start such firms. We use the specific example of the Indian and Chinese communities in the US to demonstrate this effect and explain how businesses created by members of these communities could have potentially different ways of starting and operating that can be directly traced to the differences in cultural orientation of their owners. What emerges can be summarized as: (a) different immigrant communities have different ways of accumulating and using social capital in starting and managing their ethnic ventures; (b) these dissimilarities manifest themselves in variations in the motives for forming these ventures, human resource practices and termination rates; and (c) that these variations can partly be explained by the differences in their respective national cultures.     

Signaling quality with new product preannouncements: Vaporware and the role of reference quality

This research develops a signaling game that captures the essential dynamics of new product preannouncements (preannouncement/launch/market feedback). New product preannouncements are preannouncing firms' formal efforts to inform their competitors and customers about the future availability, superior quality and introductory price of their upcoming new products. In a market, two firms compete (entrant preannounces and incumbent responds) across two periods. The entrant has private information about the true quality of a new product (the incumbent and customers do not know it), and this informational asymmetry provides the entrant with a preannouncement dilemma. Should the entrant preannounce and, if the entrant does, should the entrant tell the truth about quality? Preannouncements often get customers who might buy now from a competitor to wait for a higher quality to be available. Therefore, the entrant may have an incentive to bluff the quality of a new product in order to enhance the likelihood of customers' waiting. However, because the quality exaggeration is also likely to increase customers' quality expectations, the entrant may suffer a significant sales penalty if the entrant does not deliver the promised quality. Through the signaling game, this paper derives conditions under which such a bluff does/does not put the preannouncing firm at risk (i.e., this paper derives the separating/pooling equilibria that are the focus of signaling games).     

Why the Generalized Bass Model leads to odd optimal advertising policies

We show that the optimal advertising strategy under the Generalized Bass Model (GBM) involves beginning at an extremely low level (the lower the better) and then increasing spending throughout the planning period. This strategy remains optimal in the presence of decreasing prices that affect both margins and diffusion speed. We provide a simple explanation for why this happens. We further show that the intuitively appealing patterns of continuous decrease or increase-then-decrease (both with an uptick towards the end) identified in earlier research are also possible as optimal dynamic advertising paths under the GBM structure, but only if the advertising at launch is constrained to be higher than a particular threshold, which we identify. The constraint necessary to generate intuitively appealing strategies lowers overall profits. Therefore, the GBM generates advertising policy recommendations that most marketers would deem odd. This casts doubt on the value of the GBM for normative purposes. Other existing diffusion models are preferred when seeking normative guidance on optimal dynamic advertising policies for new products subject to word of mouth.
