交通基础设施空间建设差异化影响了中国经济增长吗--基于2001-2011年中国31个省（市、自治区）数据的实证分析

在考虑交通基础设空间网络布局特性基础上,利用2001—2011年中国省级数据和空间计量研究方法,从直接效应和空间外部效应两个层面研究了交通基础设施空间建设差异化对中国经济增长的影响。结果表明：中国交通基础设施在地理空间上已然形成了三类稳固的差异化集群;虽然交通基础设施建设对区域经济增长有着显著的正向效应,但是受其自身空间建设差异化对经济增长负向效应影响,其对经济增长应有的促进效应未能全部体现。虽然交通基础设施空间建设差异化存在显著的空间负外部效应,不过该效应正在逐年减弱。扩大交通基础设施覆盖面与提升交通基础设施存量两者对经济增长都有着相近的正向弹性,不过前者的实际操作成本要明显低于后者。     

Do Status discrepancy and socioeconomic immobility really drive compensatory consumption?

This research aimed to empirically explore whether impulsive consumption in the hospitality industry could be explained as a form of compensatory behavior that individuals engage in to cope with pessimistic self-evaluations. In this study, these self-evaluations have been operationalized as status discrepancy and perceived socioeconomic immobility. To test the hypotheses, this study used a three-way factorial design in two consumption settings: (1) leisure activities and (2) restaurant visits. Across the two studies, the results indicated that satisfactory self-assessments, rather than status discrepancy or socioeconomic immobility, lead to impulsive consumption. Despite the reversed findings, this study verified that participants jointly reflect status discrepancy and socioeconomic immobility in consumption contexts. Moreover, the findings suggest that millennials are more sensitive towards mobility information than older generations. This study sheds light on generational differences in impulsive consumption in the hospitality industry.

Contemporaneous ADR pricing: intraday dynamics during overlapping trading hours

We contribute to the literature by identifying and accurately measuring the drivers of American depositary receipt (ADR) returns contemporaneously across various global time zones. We consider ADRs as two inherently distinct asset classes – stocks and currencies – bundled into one. Throughout, we use a relatively refined, focused, and synchronized minute-by-minute data set on ADRs and all other variables. ADRs from all countries with regular trading hours that overlap with those of the US are considered individually and in clusters. We analyze the interplay of several factors that influence ADRs pricing patterns. Further, we investigate whether such patterns vary by currency, ADR, industry, and emerging/developed market classifications. Our findings indicate that synchronized returns on underlying shares comprise 68.5–74% of the explained returns in ADRs. The remaining 31.5–26% of returns are generated by movements in currency rates. These results are robust across the several models and estimation methods employed. Our findings also show persistent small price discrepancies between ADRs and dollar-adjusted underlying shares on a minute-by-minute basis, implying possible arbitrage opportunities. However, we conclude that trading and ADR conversion costs render such opportunities unattractive.     

长三角港口腹地动态演变及耦合协调度研究

明确港口腹地演变趋势、分析港腹耦合协调度,对长三角地区港腹联动发展具有重要意义。量化港口系统—腹地系统综合指标评价体系,运用高斯烟羽模型在2006、2011、2016年3个时间节点上测算长三角地区主要港口影响强度,并对腹地范围进行划分,利用耦合协调模型定量分析港口系统和直接腹地经济系统耦合协调度。研究结果表明:长三角地区港口呈现"一超多强"的格局,以上海港为中心,各港口多极发展;港口腹地范围整体稳定,局部波动,上海港的边缘腹地不断缩减;港口与腹地的耦合协调度处于上升态势,宁波—舟山港腹耦合协调度最高。     

西部欠发达地区城市化进程的经济动因分析

工业化是城市化的根本源动力,城乡收入真实的差异和能否在城市获得稳定收入是人口形成乡--城流动的经济动因,而产业集聚是推动城市化进程和促进区域发展的内生经济动因.在非均衡的大国经济发展中,城市化进程也由于地区间的差异呈现出非均衡性.从欠发达地区城市化进程的经济动因的理论和实证分析都表明,我国西部欠发达地区城市化进程中出现"滞后城市化"、"教育滞后"、"经营城市过度"等偏差现象.     

Sustainability and Accounting Education

Given the growing debate concerning the use of alternative presentation formats in corporate financial reporting, Volmer's recent paper in this journal is to be welcomed (June, 1992). Volmer conducts an experiment which compares students' perceptions of graphical and numerical presentations of financial information. From this he concludes that (i) graphical presentations improve the communication of financial information, and (ii) the integration of accounting research and teaching constitutes an effective alternative teaching method. We agree with the general message of Volmer's paper, and hope that subsequent studies will build on his exploratory work. This comment suggests a number of areas for future developments. These concern the literature base, experimental design, corporate practice and educational implications.     

Gibbs posterior inference on value-at-risk

ABSTRACT

Accurate estimation of value-at-risk (VaR) and assessment of associated uncertainty is crucial for both insurers and regulators, particularly in Europe. Existing approaches link data and VaR indirectly by first linking data to the parameter of a probability model, and then expressing VaR as a function of that parameter. This indirect approach exposes the insurer to model misspecification bias or estimation inefficiency, depending on whether the parameter is finite- or infinite-dimensional. In this paper, we link data and VaR directly via what we call a discrepancy function, and this leads naturally to a Gibbs posterior distribution for VaR that does not suffer from the aforementioned biases and inefficiencies. Asymptotic consistency and root-n concentration rate of the Gibbs posterior are established, and simulations highlight its superior finite-sample performance compared to other approaches.     

中国区际消费率差异研究

从消费率角度出发研究中国区际消费差异的情况及原因可以发现,现在东部处于消费率基本稳定时期,中西部处于消费率下降时期.区际消费率差异是由于东中西部处于不同发展阶段引起的,最终消费率降低的主要原因是国民收入不公.在不影响发展的情况下,加大国民收入向居民分配的额度,可以有效提高东部居民消费率,维持住中西部居民消费率,从而缩小区际消费率差异,提高最终消费率.     

论信用证开证行的独立拒付权

开证行在审单过程中,发现单据存在瑕疵,应根据UCP500的规定予以拒付.开证行在审单过程中联系申请人并不意味申请人有拒付权.据UCP500的规定,拒付权是开证银行的权利,拒付权应由银行独立行使.
