基于中部地区崛起战略的河南省地域空间组织研究

河南省在中部地区崛起战略中占据重要的战略区位,不仅要注重自身发展,还应积极争取与邻近省份市县地域的有效对接,合力并举助推中部地区崛起战略的顺利实施。首先采用分形理论以及空间分析方法研究了河南省的地域结构特征,发现城市分布格局以郑州市为中心进行自组织演化,市县分布多沿交通干线,"轴带+圈层"的复合型地域结构显现;然后采用统计分类、城市规模分级方法,分析了河南省的经济、城镇以及交通发展现状,发现经济发展区域差异显著,城镇规模序列结构不完善,陆路综合交通网络发达;最后基于河南在中部地区崛起中的战略地位,提出了改善河南地域结构的结点优化、轴带组织和面域扩展相结合的系统化空间组织路径。

China's one belt one road initiative: The impact of trade facilitation versus physical infrastructure on exports

The One Belt One Road (OBOR) project is perhaps China's most significant international relations initiative in recent times. It is based on openness, harmony, inclusivity, mutual benefit and market operations and aims to connect the economically vibrant East Asia and the developed Europe by land and by sea, and in the process, it brings growth and development to tens of countries along the modern Silk routes. In this paper, we compare the impact of the main initiatives of OBOR, namely enhancements in physical infrastructure and improvements in border administration, on the trade of countries that have signed on to this project, especially countries along the six economic corridors. We find overwhelming evidence that shows improvements in border administration has the greatest impact on exports of corridor countries. Although physical infrastructure is important for trade, the Chinese government should place equal attention to improvements in trade facilitation to ensure trade routes operate seamlessly across the various corridors.     

Exploring the nexus between bank market power and exports

Although the literature underlines the importance of finance in international trade, no prior study has examined the causal links between market power in banking and export performance. Using a world sample over the 1997-2010 period, and accounting for both observed and unobserved country heterogeneity, we find a positive effect of bank market power on exports, especially in high-income countries. We also document that this export-enhancing effect is more potent in informationally opaque markets. Our findings accord with information hypothesis which suggests that market power in banking induces stronger bank-firm relationships which can generate benefits for both borrowers and lenders. Policy interventions should, therefore, promote the supply of relationship lending as a means to mitigate informational asymmetries in the export market.     

基于SFA的鲁浙苏城商行技术效率对比及影响因素研究

文章采用随机前沿方法（SFA）估计了江苏、山东、浙江三地19家城市商业银行2007年-2012年的技术效率，在对比分析的同时研究影响其技术效率差异的非效率因素。实证结果表明，三地城商行六年来技术效率逐年提升，且浙江、山东五家城商行六年平均技术效率值位居前列，并表现出较为稳定的技术效率状态；法人治理结构是影响样本城商行技术效率差异的重要因素，适度分散化的股权结构及战略投资者持股与样本城商行的技术效率呈显著正相关。     

The shape of small sample biases in pricing kernel estimations

Numerous empirical studies find pricing kernels that are not-monotonically decreasing; the findings are at odds with the pricing kernel being marginal utility of a risk-averse, so-called representative agent. We study in detail the common procedure which estimates the pricing kernel as the ratio of two separate density estimations. In the first step, we analyse theoretically the functional dependence for the ratio of a density to its estimated density; this cautions the reader regarding potential computational issues coupled with statistical techniques. In the second step, we study this quantitatively; we show that small sample biases shape the estimated pricing kernel, and that estimated pricing kernels typically violate the commonly believed monotonicity at the centre even when the true pricing kernel fulfils these. This contributes to an alternative, statistical explanation for the puzzling shape in pricing kernel estimations.     

Life Cycle Price Trends and Product Replacement: Implications for the Measurement of Inflation

The paper explores the extent to which products follow systematic pricing patterns over their life cycle and the impact this has on the measurement of inflation. Using a large U.S. scanner data set on supermarket products and applying flexible regression methods, we find that on average prices decline as items age. This life cycle price change is often attributed to quality difference in the construction of CPI as items are replaced due to disappearance or during sample rotations. This introduces a systematic bias in the measurement of inflation. For our data we find that the life cycle bias leads to the underestimation of inflation by around 0.30 percentage points each year for the products examined.     

Information diffusion and the predictability of New Zealand stock market returns

This paper examines the impact of international predictors from liquid markets on the predictability of excess returns in the New Zealand stock market using data from May 1992 to February 2011. We find that US stock market return and VIX contribute significantly to the out‐of‐sample forecasts at short horizons even after controlling for the effect of local predictors, while the contribution by Australian stock market return is not significant. We further demonstrate that the predictability of New Zealand stock market returns using US market predictors could be explained by the information diffusion between these two countries.
