电子商务中的信息安全及应对方法

随着互联网的全面普及，基于互联网的电子商务应运而生。它的高效率、低成本等优点越来越受到社会的认可。而作为一种全新的商务模式，信息安全的保障是电子商务实施的前提。     

Contracts with endogenous information

I study covert information acquisition and reporting in a principal agent problem allowing for general technologies of information acquisition. When posteriors satisfy two dimensional versions of the standard First Order Stochastic Dominance and Concavity/Convexity of the Distribution Function conditions, a first-order approach is justified. Under the same conditions, informativeness and riskiness of reports are equivalent. High powered contracts, that make the agent's informational rents more risky, are used to increase incentives for information acquisition, insensitive contracts are used to reduce incentives for information gathering. The value of information to the agent is always positive. The value of information to the principal is ambiguous.

The role of externalities and information aggregation in market collapse

We examine the role that belief, network externality, and information aggregation play in inefficient market collapses. After receiving consecutive negative shocks, some ex-ante identical Bayesian agents will be discouraged about the unknown state of the market they invest; therefore, they will stop investing. This decision will have two effects: first, it will cause agents to aggregate information through social/observational learning; second, it will decrease the network externality effect. We show that there might be an inefficient market collapse if the externality effect diminishes too much, and the cost of re-entry to the market is too high. We also analyze the effects of strategic delay and experimentation on the exit decision of the agents. I especially thank Thomas D. Jeitschko, Matthew Mitchell, B. Ravikumar Ted Temzelides.

企业的知识创造及情报服务

本文根据若干知识经济的论著，对四种类型的知识从认识论角度来对比说明其明晰知识和隐含知识的特点，着重说明企业也是人类知识，尤其是隐含知识的重要来源，企业在知识传播与利用、在技术的投资及技术创新中具有的重要作用；最后提到，知识经济中，知识的生产、传播与交流形成了知识网络，并与技术创新的网络结构相一致。促进创新需要各行动者——企业、实验室、研究机构及消费者之间的联系，这种联系和企业的竞争又促使以信息分析为基础的商业情报服务业的发展。     

How does a cluster relocate across the border? The case of information technology cluster in the Taiwan-Suzhou region

Since the end of the Cold War, cross-border regions have proliferated at the borders of formal socialist countries, especially in China. Existing accounts of these emergences treat them either at the macro-level, focusing on political initiatives, or at the micro-level, with emphasis on social and economic relations. This paper uses the Taiwan-Suzhou cross-border region as a case study for suggesting a meso-level approach, arguing that as a result of continuous interactions between individual Taiwanese information technology firms and opportunity structures generated by the selective opening of the Chinese border, the formation of cross-border high-tech regions is shaped and determined at the level of the industrial system. The industrial system acts as a platform for coordination and cooperation between local elites and foreign investors and among individual firms within this system. The formation of the cross-border high-tech region thus involves the relocation and institutional re-embedding of industrial systems across the border, which has been accompanied by the systemic building of Taiwanese firms on the one hand, and the institutional innovation of Chinese local states on the other.     

Technology transfer in the IT industry: A Korean perspective

Recently Korean Government announced ambitious IT strategy to establish Korea as one of leaders in world IT market. To implement this strategy, technology transfer from research lab to market should be successfully performed. This study is to identify factors influencing technology transfer and to examine contribution of these factors on success of technology transfer in Korean IT industry. Survey results show that technology project leaders evaluated “Concreteness of Technology” as the most influential factor for technology transfer, followed by “Communication Channels,” “Collaboration among Participants,” “Management Support,” “Government Support,” and “Incentives for Transfer.” Out of 135 technology transfer projects, respondents rated 33 projects as sustaining (28.44%), 38 as promoting (28.15%), 26 as demonstrating (19.26%), 27 in incubating (20.00%), and the remaining 7 in imaging stage (8.15%). This statistics means that 28.15% of technology transfer projects did not reach production stage. Regression analysis identifies that “Communication Channels,” “Management Support,” “Concreteness of Technology” “Sense of Common Purpose,” and “Awareness of Technology Transfer” were statistically significant in explaining success of technology transfer.

Industry concentration in common value auctions: theory and evidence

We examine theoretically and experimentally two countervailing effects of industry concentration in common value auctions. Greater concentration of information among fewer bidders reduces competition but increases the precision of private estimates. We demonstrate that this generally leads to more aggressive bidding. However, the reduction in competition dominates the informational effects, resulting in lower prices. We examine these hypothesized effects experimentally by conducting a series of auctions with constant informational content but distributed among a varying number of bidders. The experimental results are consistent with our theoretical predictions.
