论东亚建立不确定性干预边界的汇率合作机制

论文首先分析东亚实施钉住混合货币篮的汇率目标区制存在的弊端,从新的视角提出,这一地区应建立以不确定性干预边界为核心的汇率合作机制;进而指出,这一汇率合作机制更具有弹性,可使各国规避货币冲击,易于搭建汇率合作的平台。     

从交易费用看农村信用社的制度选择--为合作制正名

从交易费用的角度看,合作制对于降低农村信贷市场交易费用具有明显的优势,是一种适合我国当前农村经济实际的金融产权制度.而我国农信社之所以问题严重,是在于目前的合作制是一种变异的合作制,以及建立在这种变异合作制之上的不合理的治理结构,导致了运行中较高的交易费用.文章提出,真正落实合作制才是农信社改革的方向,只有这样才能为农户提供一个融资便利的机制,使农信社服务于"三农",促进农村经济的发展.     

产品差异与技术差距影响研发溢出的理论探讨

在传统研发溢出效应假设基础上，通过技术差距将溢出效应与产品差异有机联系起来，并通过构建双寡头企业两阶段博弈模型对研发卡特尔、生产卡特尔、完全合作等不同形式合作联盟的均衡水平和福利变化进行分析比较。研究证实：当企业间技术差距较小时，完全合作或研发卡特尔能有效提高企业利润和社会福利；而当技术差距较大时，研发阶段的合作不仅无法激励企业进行研发投入，还会抑制企业创新的积极性。此外，与完全合作相比，局部合作具有更强的稳定性和可持续性，尤其是在产品差异程度较大的情况下，研发卡特尔最为稳定。     

Direct intervention or indirect support? The effects of cooperative control measures on farmers’ implementation of quality and safety standards

In recent years, labor-intensive agricultural products from developing countries have exhibited inferior performance in international trade due to quality and safety incidents, among which pesticide residue is a major issue. Aiming to improve food quality and safety in the context of cooperatives, we introduced three categories of control measures: outcome control, process control and social control. Based on the Pre-Harvest Interval Standard (PHIS), we selected three indices, farmers’ implementation rate of PHIS, absolute distance to PHIS and relative distance to PHIS, to evaluate appropriateness of pesticides use, reduction of pesticide residue and safety improvements of agricultural products. By using random sampling survey data, we empirically analyzed the marginal effects of control measures and their combinations on food quality and safety standards. The empirical results show that implementing process control, namely, unified production standards or supply of unified agricultural inputs, can comprehensively improve farmers’ implementation rate of PHIS, absolute distance and relative distance to PHIS respectively by 34.9%, 3.2 days and 46.0% on average. While the effects of outcome control (safety inspection) and social control (bonus-penalty incentive or training) are restricted to other measures. Therefore, we suggest cooperatives should take farmers’ features, implementation conditions and the effects of control measures into consideration in order to make a sustainable management plan for improving food quality and safety and enhancing competitiveness in international markets.

Equal sacrifice and fair burden-sharing in a public goods economy

Applying a willingness-to-pay approach known from contingent valuation in environmental economics, we develop an ordinally based measure for the size of individual sacrifice that is connected with an agent’s contribution to a public good. We construct a selection mechanism that picks the unique efficient solution among all allocations that have an equal sacrifice as defined in this way. We show that the solution thus obtained corresponds to Moulin’s egalitarian equivalent allocation, conforms to both the ability-to-pay and the benefit principles, and has much in common with the Lindahl equilibrium.      

Choice-based learning: lecture-based or team learning?

This study investigates choice-based learning as a choice between lecture-based or team learning in a large class at a large university in a European country. The study was designed as a between-subjects quasi-experiment where students were allocated their preferred learning approach. Data were collected for eight consecutive years (2008–2016). Based on quantitative and qualitative data, this study investigates the effect of choice-based learning on choice satisfaction, student selection and on student learning outcomes. The results show that team learning has a positive effect on learning outcomes. If students are faced with the choice, the majority select lecture-based learning. Additionally, both student groups are satisfied with their selected learning paths but selected them for specific reasons. Finally, choice-based learning provides job satisfaction for the instructors of both learning paths. These results can re-energize the ongoing discussion on why and how to engage students in learning activities.     

高新技术企业多元合作研发模式选择

以资源基础理论、交易成本理论为基础,探讨了开放环境下企业不同合作研发模式对创新绩效的影响,以及知识和技术的中介作用与内部研发的调节作用。基于2014-2016年816家河北省高新技术企业数据的长短期对照检验结果表明：不同合作研发模式对创新绩效有不同影响,且无论长短期,境外合作的影响最强,产学、产政合作长期效应强,产研合作短期效应强;知识和技术起部分中介作用,内部研发正向调节产学、产政合作绩效,负向调节产研、境外合作绩效。研究结论对于高新技术企业选择研发战略具有重要意义。     

包容性制造业服务化协作网络特征与实现路径研究

包容性制造业服务化协作网络建设有助于提高网络运作效率、增强网络竞争力,其具有异质性、公平性、合作性等特征。核心制造企业能力及网络成员关系是包容性协作网络实现路径的两个重要维度。在基于价值链的协作网络中,核心制造企业产品生产制造能力在包容性协作网络构建中发挥着极其重要的作用。同时,也离不开网络成员间的信任、沟通与学习;在基于解决方案的协作网络中,核心制造企业网络管理能力在提高协作网络包容性中发挥着极其重要的作用,网络成员间的信任、沟通、学习尤为重要。
