The impact of prudential toolkits on loan growth in Central and Eastern European banking systems

This paper examines the effects of prudential policy on loan growth in 11 Central and Eastern European banking systems, spanning the period from 2000 to 2015. Based on the measures taken by the authorities of our sample countries, we build several prudential indices. Additionally, we control for the effects of several country-specific factors and bank-specific characteristics. Finally, we test the homogeneity of these effects, accounting for cycle, ownership, and bank effects. Generally, the empirical findings reveal a negative correlation between prudential toolkits and credit growth, with a conspicuous impact for tools targeting lending activity. We see that the effects of a change in the lending framework on loan growth are heterogeneous when we account for crisis and cycle patterns. Furthermore, the interaction between ownership and crisis reveals that, in normal times, foreign banks recorded higher loan growth compared to domestic banks. The opposite is true in turbulent times. The analysis of interactions between credit-based measures and bank-specific variables show that the effects of prudential actions depend on the bank size and leverage.     

产品开发中企业引入消费者参与的时机决策：一个基于消费者偏好信号传递的分析

针对“企业可以在产品开发的不同阶段引入消费者参与”的实践观察，本文构建消费者与企业之间的不完全信息动态博弈模型来研究“在何种条件下，企业选择产品开发前端（后端）引入消费者参与，从而激励消费者真实传递其偏好信息”这一问题。研究表明：存在外生参数（消费者讨价还价能力和参与净效用表征），使得前端和后端引入消费者参与均（或二者中只有一个）能够实现消费者真实传递其偏好信息的分离均衡；前端参与时，分离均衡要求企业通过新产品价格分担（攫取）消费者的负（正）参与净效用，而后端参与不需要这种分担（攫取）机制；在前端和后端参与均能实现消费者真实传递其偏好时，前者优于后者的条件是参与净效用为正。     

重症患者CT增强检查的护理分析

目的探讨在重症患者CT增强检查过程中加强护理干预的效果。方法选取2013年1月至2014年1月我院行CT增强检查的128例重症患者的临床资料进行归纳整理,分析检查过程中患者的不良反应发生情况及CT增强检查结果。结果除1例患者因气喘、憋闷,未能完成增强检查外,127例患者均顺利完成增强检查。结论在重症患者CT增强检查的过程中加强护理干预,可有效预防意外事故的发生,保证检查顺利进行。     

货币政策对收入分配影响效应的国外研究进展

传统观点认为货币政策是一种总量型的调控政策,但近年来国外学者有关货币政策对收入分配影响效应的研究越来越多。后凯恩斯主义学派的研究主要基于内生货币供给理论展开,强调货币政策通过利率调整这一外生变量对收入分配产生影响。新古典经济学派的研究主要围绕合理预期展开,认为只要中央银行制定的货币政策规则保持长期不变,且始终公开透明,就可以为人们提供公平的规则和平等的机会。新凯恩斯主义学派以菲利普斯曲线的研究为主线,探讨的重点在于劳动收入份额是否能完整地反映通货膨胀动态变化、货币政策是否应将劳动收入份额纳入目标考虑范围。从实证结果来看,大多数学者基于各国历史数据验证了货币政策对收入分配的影响效应。从传导机制上看,货币政策可通过收入构成、金融分割、资产配置、储蓄再分配等四个渠道对收入分配产生影响。从政策启示上看,多数学者认为,合理的货币政策可提高就业、促进劳动收入增长、降低通货膨胀,从而直接或间接地缩小收入分配差距、促进社会公平。     

大数据时代下电子商务平台的探索和研究——以淘宝网为例

随着网络用户的日益增长,互联网记录着大量的用户个人信息和由智能终端产生的图片和信息,这些信息爆炸性的增长,并不断涌入网络海洋,产生海量的数据信息。在电子商务环境中大数据处理将会发展出更多强大和多元的功能。本文以淘宝网为例,分析研究如何合理利用数据,为企业的经营模式做出相应调整,并且在变化中不断进行企业新技术、新方法和新思路的探索。同时指出数据泄露的隐患,并给出相应建议。     

Do vertical spillovers differ by investors’ productivity? Theory and evidence from Vietnam

Developing countries are eager to host foreign direct investment to receive positive technology spillovers to their local firms. However, what types of foreign firms are desirable for the host country to achieve spillovers best? We address this question using firm‐level panel data from Vietnam to investigate whether foreign Asian investors in downstream sectors with different productivity affect the productivity of local Vietnamese firms in upstream sectors differently. Using endogenous structural breaks, we divide Asian investors into low‐, middle‐, and high‐productivity groups. The results suggest that the presence of the middle group has the strongest positive spillover effect. The differential spillover effects can be explained by a simple model with vertical linkages and productivity‐enhancing investment by local suppliers. The theoretical mechanism is also empirically confirmed.

乡村生态旅游促进新型城镇化的实证分析--以西安市长安区为例

在生态资源富集又邻近大城市的乡村地区发展乡村生态旅游，能够有效地促进新型城镇化、助推新型旅游小城镇的形成。文章在界定核心概念并进行理论机理分析的基础上，以西安市长安区为例，对其2002—2014年间乡村生态旅游与新型城镇化之间的关系进行实证检验，结果表明：二者确实存在高度的正相关关系，且前者是后者的重要原因。因此，应采取有力措施发展这些地区的乡村生态旅游：第一，进一步加大政府对乡村地区基础设施的投资，彻底实现城乡公共产品供给的均等化；第二，引导民间资金、技术、管理等有序合理、规模适度地投入乡村生态旅游业；第三，务必加强乡村生态旅游业发展过程中的环境监管等。     

Gender Diversity in the Boardroom and Risk Management: A Case of R&D Investment

Increasing gender diversity in the boardroom has been promoted as a way to enhance corporate governance and risk management. This study empirically examines whether boards with more female directors play a role in reducing R&D risk. We first show that female directors help to reduce the positive relationship between R&D investment and future performance volatility. We then report that firms with more gender-diverse boards exhibit a lower adverse effect of R&D on the cost of debt. These results are robust to endogeneity analysis, alternative measures of gender diversity and risky investment, and other sensitivity tests. Overall, our results suggest that female directors improve board effectiveness in risk management with respect to R&D investment.
