International spillovers of China's structural reforms

This paper sheds light on the international spillovers of China's reforms in upgrading industrial capabilities, liberalizing capital account, internationalizing the renminbi, and transition to flexible exchange rates. Drawing on two-country New Keynesian model of endogenous entry and portfolio adjustment, we find that China's industrial upgrading that peddles on yuan appreciation lifts all boats through global production network irrespective of capital account convertibility, degree of renminbi internationalization, and exchange rate reform. Feasibility of appreciation-driven upgrading is called into question, however, when renminbi reform and capital account liberalization go in parallel. We also show that international spillovers disappear once renminbi internationalization is associated with liberalized capital account and flexible renminbi exchange rates.     

Optimizing suicide and trespass prevention on railways: a problem-solving model from the RESTRAIL project

Suicides and trespassing accidents result in more than 3800 fatalities in Europe, representing 88% of all fatalities occurring within the EU railway system. This paper presents a problem-solving model, which consists of a multistep approach structuring the analysis of a suicide or trespass-related problem on the railways. First, we present the method used to design, evaluate and improve the problem-solving model. Then we describe the model in detail: it comprises six steps with several subsequent actions, and each action is approached through a checklist of prompting questions and possible answers. At the end, we discuss the added value of this model for decision makers and its usability in the selection of optimal prevention measures.

基于专利信息的产业技术竞争优势测度模型构建与实证研究

提出产业技术竞争优势的概念，并探讨其"规模-质量-价值"三维模型和测度指标体系；构建产业技术竞争优势指数，利用熵值法设置权重，采用合成指数法计算产业技术竞争优势指数。以世界生物医药产业主要国家（中、美、德、日）1996-2016年样本数据进行实证研究。结果表明：中国生物医药产业技术竞争优势指数及分指数总体保持上升趋势，其中规模指数增长较快，价值指数次之，质量指数发展居于末位；美国、日本和德国竞争优势指数相近，均具有较强的竞争优势；中国产业技术竞争能力处于劣势地位，规模维度方面中国与其它三国差距较小，价值维度差距次之，质量维度差距较大。     

珠三角工业设计与工业互动比较研究：双重需求拉动与设计驱动增长的区域验证

动态比较珠三角工业发展阶段和设计水平不同的典型区域内，工业用户和最终消费者用户双重需求拉动设计创新以及设计驱动工业增长作用机制的异同，提出克服互动系统短板并因地制宜实施设计驱动转型升级的对策建议。基于SVAR建模的脉冲响应和方差分解分析发现：珠三角工业确实可以通过工业设计创新驱动实现内生性可持续增长，而设计水平的地区差异对设计驱动绩效有调节作用；工业发展质量和结构欠佳，无法有效拉动区域工业设计创新，是珠三角多数地区工业设计有效需求不足的根本原因。区域工业设计与工业互动系统的短板是缺乏内行和挑剔的最终消费者有效需求。最后基于模型稳健性检验，提出因地制宜科学实施设计驱动发展战略的对策建议。

The impact of maize price shocks on household food security: Panel evidence from Tanzania

Using three waves (2008/09, 2010/11, 2012/13) of the Tanzanian National Panel Survey, this study investigates the impact of maize price shocks on household food security. Between 2008/09 and 2012/13, calorie intake stagnated for urban households, yet sharply deteriorated for rural households. The latter was driven by a significant decline in the consumption of the major staple maize which showed strongest price hikes among all major food items. Fixed-effects regressions indicate a clear negative relationship between maize prices and average household energy intake. Almost all population groups were found to be negatively affected by maize price shocks, with rural landless households being the most vulnerable group. In particular, a 50 percent rise in maize prices decreases caloric intake for rural (urban) households on average by 4.4 (5.4) percent, and for rural landless households by 12.6 percent. Results further indicate that subsistence agriculture can act as an effective strategy to insure against food price volatility.
