Network patterns and competitive advantage before the emergence of a dominant design

This study examines the performance implications of the alliance networks of 49 firms that competed for two technology standards in the U.S. local area network industry from 1989 to 1996. During the race to define a dominant design, individual firms attract the suppliers of complements by building alliance networks to favor the firms' preferred technology standard. Controlling for the number of suppliers in each technology standard community and the extent of technical progress achieved by individual firms, the panel data analysis shows that central firms with high ego network density, coupled with a strategic intent to acquire and share knowledge broadly within the technological community, achieve better innovation performance. The size of the technological community and some random events in the early formation of the industry do not provide a sufficient explanation of how these firms gain the diverse support of suppliers or enhance their competitive advantage. By demonstrating the independent and contingent effects of alliance network properties, this study explains how network patterns might enhance or limit the benefits of alliance networks when focal firms embrace different innovation strategies.

新时期国民生活水平和生活质量变迁论略——兼谈存在的问题及主要对策

新时期以来,我国国民的生活水平有了很大的提高,主要表现在GDP的持续增长和人均可支配收入的增加。生活质量也有了很大的提升,主要表现为衣食的多样化和精致化、居住环境的宽敞化和人文化、生活用品高档化、人口素质不断提高和休闲生存状态方面等。但是,从总体上说,我国人民的生活水平和生活质量还存在着很多问题。彻底打破城乡二元结构,对国家的产业结构进一步调整和完善社会保障制度是当前应该采取的主要对策。

On the efficiency of the negligence rule

The three versions of the negligence rule discussed in the literature differ regarding whether a negligent injurer is liable for the entire loss or only for the incremental loss; or regarding whether negligence is defined as failure to take at least due care or failure to take a cost‐justified precaution. It is shown in the paper that the incremental version with untaken precaution notion of negligence is not efficient; not even for the unilateral case. The paper also establishes, for the bilateral case, the efficiency of the incremental version with the shortfall‐from‐due‐care way of defining negligence.     

URBANIZATION,HEALTH AND HUMAN STATURE

Economic growth has not always generated improvements in a population's health. Biological indicators of human well‐being, including stature, suggest the march to prosperity was not a steady one, and these biological indicators offer estimates of the health costs associated with modern economic growth. We employ an international data set to study the socioeconomic benefits and health costs associated with the transition to modern economic growth during the nineteenth century. We find that while the growth of GDP per capita had a positive impact on the stature of Western populations, prior to the mastery of the germ theory of disease, urbanization had a strong negative impact.
