The social process of internet appropriation: Living in a digitally advanced country benefits less well-educated Europeans

We generalize and extend the sequential model proposed by the resources and appropriation theory to explain the digital divide in the European Union plus the United Kingdom (EU27+UK). We measure the theoretical constructs of the model with data provided by the EU and test the theoretical predictions using a partial least squares structural equation model. We find support for the hypothesized relationships but find that the effects vary depending on the digital development level of countries. While education overall is the primary determinant of the social production of digital inequalities, a country's digital development level is crucial for less well-educated Europeans. These findings have theoretical and practical implications: (1) they call into question the homogeneity of the effect of causal relationships and the assumption that individuals differ only in terms of motivation, access, and digital skills, and (2) they indicate that socially disadvantaged Europeans benefit from living in more digitally developed countries.

技术竞争导向下的创新投入与企业成长性——来自科技型中小微企业的调查数据

基于我国科技型中小微企业的调查问卷数据,本文研究了创新投入与企业成长的关系和作用机理,并探讨了内外部创新环境对二者关系的异质性影响.研究结果表明,创新投入与科技型中小微企业成长性正相关;进一步研究发现,提高竞争优势和降低外部融资约束是创新投入影响科技型中小微企业成长性的中介路径;内部知识吸收和外部创新共享具有调节效应,均对创新投入与科技型中小微企业成长性的正向关系具有促进作用.本文的研究为我国创新战略实施与企业投资决策优化提供了经验证据和决策参考.     

Open access,common property and scarcity rent in fisheries

Open access resources are frequently not managed efficiently, resulting in falling stock levels and a declining income for fishermen. In the late 1970's, the policy response to this problem was the implementation of 200-mile fishing zones, which enabled the European Union to formulate and implement the Common Fisheries Policy, aimed at (among other things) conservation and distribution of available stocks. In Germany, this shift from an open access regime towards a common property regime had favourable outcomes. The trend of falling prices was reversed. The conclusion was that intertemporal efficiency had increased as a result of (inter)governmental policy. Apparently, a wedge was formed between price and marginal harvesting costs, implying that scarcity rent had returned as a component of prices.     

Vertical Restraints and Market Access

This paper analyzes vertical restraints in relation to market access issues. In Section II we briefly review the recent three major trade conflicts between Japan and the USA in light of vertical restraints. In Section III we review the major policy lessons of the economics literature of vertical restraints, and analyze whether we need a special treatment for vertical restraints abroad for a market access reason. In Section IV we evaluate the policy options towards foreign foreclosure and suggest that nondiscriminatory application of foreign or home competition policy should be the mechanism to address such concern instead of trade policy actions such as voluntary import expansions.     

不完全信息与网络产业激励性规制改革

规制体制改革的核心是解决信息不对称下的最优激励问题，规制体制设计的关键就是要设计有效的激励合约，为企业提供适当的激励以达到成本效率，从激励角度看，价格上限规制的效率最高，竞争是重要的激励性体制，网络产业竞争体制形成的关键是约束在位运营商排斥竞争行为和建立有效的互联资费政策。     

纵向一体化网络的接入定价研究

中国铁路、煤气、自来水、邮政等绝大多数网络型产业的结构改革将选择纵向一体化与自由接入作为突破口，研究纵向一体化网络的接入定价理论和政策已成为中国网络型产业规制政策研究的一个重要问题。本文首先依据资源最优配置、次优配置、生产效率等原则，研究了不同的接入定价理论，详细探讨了不同的接入定价方法，最后进一步分析了纵向一体化网络在不同政策目标下的接入定价政策选择。     

对金融衍生品市场内幕交易的一些新思考--澳大利亚现行的反内幕交易法及其带给我们的若干启示

本文着眼于澳大利亚在治理金融衍生品市场内幕交易中积累的丰富经验,针对一个崭新的前瞻性课题,即金融衍生品市场的内幕交易问题展开研究。作者认为,由于内幕交易与信息非对称性之间存在的内在冲突,实际上反内幕交易法规很难有效地阻止金融衍生品的内幕交易行为,过于复杂的反内幕交易法规会对市场产生一些负面影响,而放松内幕交易监管这一新思维将对市场的良性发展更为有益,应该让市场来决定内幕交易行为的“存亡”。但目前最为现实、温和的选择仍然是修改现行反内幕交易法,以维护市场的公平性和有效性。最后,笔者对如何缓解中国目前内幕交易猖獗的现状提出建议。
