Trade networks and economic fluctuations in Asian countries

The paper presents a new methodology, based on tensor decomposition, to map dynamic trade networks and to assess its strength in forecasting economic fluctuations at different periods of time in Asia. Using the monthly merchandise import and export data across 33 Asian economies, together with the US, EU and UK, we detect the community structure of the evolving network and we identify clusters and central nodes inside each of them. Our findings show that data are well represented by two communities, in which People's Republic of China and Japan play the major role. We then analyze the synchronisation between GDP growth and trade. Furthermore we apply our model to the prediction of economic fluctuations. Our findings show that the model leads to an increase in predictive accuracy, as higher order interactions between countries are taken into account.

论格式条款的司法规制——从诚实信用原则视角分析

格式条款的大量使用在给人们带来方便、快捷的同时，也带来了潜在的不公平的可能性。现代司法实践的发展使得司法规制成为对格式条款进行规制的主要方式。对格式条款司法规制需要依据诚实信用原则，通过判断格式条款是否为合同之条款、解释格式条款之疑义、认定格式条款之效力来进行。     

Current Account, Capital Formation and Terms of Trade Shocks: a Revisit of the Harberger-Laursen-Metzler Effect

This paper extends the Blanchard model of a closed-economy to a three-good (exportable, importable and non-tradable goods) open-economy model with capital accumulation and uncertain lifetimes to study the impacts of terms of trade shocks on the current account. The simulation results show that a model with uncertain lifetimes is more appropriate to describe a small open economy like Taiwan at the steady-state equilibrium than a model with infinite lifetimes. We find that the Harberger-Laursen-Metzler effect is discernible for temporary or permanent terms of trade shocks. Furthermore, the steady state is a saddle point and the speed of convergence of capital and consumption is quite low.     

Option pricing in the presence of natural boundaries and a quadratic diffusion term

This paper uses a probabilistic change-of-numeraire technique to compute closed-form prices of European options to exchange one asset against another when the relative price of the underlying assets follows a diffusion process with natural boundaries and a quadratic diffusion coefficient. The paper shows in particular how to interpret the option price formula in terms of exercise probabilities which are calculated under the martingale measures associated with two specific numeraire portfolios. An application to the pricing of bond options and certain interest rate derivatives illustrates the main results.

辽宁省大学生亚健康现状及成因研究

以辽宁省6所不同类型院校的1 200名学生为研究对象,对他们的亚健康现状和影响因素进行了调查,可以看出我省大学生亚健康检出率略高于其他省份。影响辽宁省大学生亚健康症状的主要因素:对自身健康的关注度不够、饮食不规律、缺少合理的睡眠和适当的体育锻炼、闲暇时间睡懒觉及上网聊天打游戏;学校相关部门对学生身体状况的重视程度不够,缺少家人的影响与监督;大学生对未来前程的担忧和就业的压迫感、对自身工作能力的不自信。     

探地雷达在公路改扩建工程检测中的应用

公路改扩建工程在广东省正处于快速发展时期,如何准确得到路面病害情况,是旧路处治方案制定面临的主要问题.依托开阳高速改扩建工程,采用三维探地雷达对旧路进行病害检测,得到道路表面及内部的病害分布情况,并分别与人工徒步调查路况及开挖后内部实际情况进行比对.结果表明:当三维探地雷达检测采样间距设置为2.0 cm、驻波时间设置为0.6 ms、时窗设置为85 ns时,可达到较好的检测精准度;三维探地雷达可实现对路面结构内部不同深度位置的裂缝病害进行探测,精确识别3 mm宽裂缝,并了解裂缝的发展方向及性质.
