Simplifying the input–output analysis through the use of topological graphs

In this paper, we revise some ideas on Graph Theory and develop them to explain and determine three usual concepts of Input–Output Analysis: fundamental products, autonomous sets, and indecomposable matrices.Firstly, we define a digraph associated with the given economic system (i.e., with its technical coefficients matrix). Secondly, we consider topological properties of this graph to study the economical concepts previously mentioned. Thirdly, we describe different, original algorithms to make the calculations easier. Finally, we give an example from a real economy, Andalusia (a region in Spain).Along this paper, we also discuss the advantages of this new approach and present some ideas to ease its application in the future research.     

The change on the foundations of the Turkish accounting system and the future perspective

Accounting is a social construct and shaped by the society in which it operates. Needs of society are the most important influencing factors in the development of accounting in a country. Though in today's open system societies, the change in the accounting is inevitable, it should not be forgotten that accounting is not only a practice but also a discipline which has got theoretical and historical backgrounds. In this regard, this paper notes the changes in Turkish accounting system from the theoretical and historical perspectives.     

The dynamics among G7 government bond and equity markets and the implications for international capital market diversification

This paper investigates potential international capital market diversification gains from relationships between global government bond and equity markets. Its primary contributions are (1) including both government debt and equity markets in the investigation of global diversification gains, (2) basing the analysis on real, risk-adjusted returns, and (3) evaluating both variance decompositions and impulse responses, as well as long-term relationships for international U.S. dollar investors. We find the cointegration, variance decomposition, and impulse response function results indicate interdependence and reduction in gains to international diversification.     

Ex ante performance from ex post models of global equity market correlations

Analysis of ex post returns reveals the time series properties of correlations, but ex ante correlations are required for efficient diversification. We find that a time-varying parameter model offers the best fit to ex post global equity market correlations, suggesting changing mean correlations and changing rates of adjustment back to the means. Nevertheless, we do not find improved forecast performance from time-varying parameter models in holdout periods. The added complexity of time-varying models does not translate into lower forecast errors.     

存款保险的行为金融分析

在银行挤兑和存款保险的理论研究方面,Byrant、Diamond和Gibbons等人提出的模型各有侧重,但都不能解释银行挤兑事件中的非理性行为.本文运用行为金融的期望理论和心理账户对低效率均衡出现的原因以及存款保险制度的作用和银行救助进行了分析,指出我国建立存款保险制度的必要性和意义.     

SECI框架下的税务文化内生动态初探——基于基层税务机关文化建设实践的探索

目前,对于税务文化建设的研究大多从税务机关主观的角度出发,研究加强或创新税务文化建设的手段和方法,而对于作为客体的税务文化本身其形成、发展的动态规律,则研究甚少。本文拟借鉴企业知识管理的SECI模型,结合基层税务机关近几年来的实践,对税务文化的形成和发展规律进行探讨,并结合税务文化发展规律对SECI模型进行改进,以便找准着力点加强税务文化建设。     

中国农村固定资产投资产出弹性评价——基于灰色理论模型的实证分析

本文阐述了灰色系统理论的实现过程,通过构建农村固定资产投资需求的灰色理论模型,预测出各地区农村固定资产投资与第一产业生产总值。在此基础上通过回归分析剖析了各地区农村固定资产投资的产出绩效。分析表明:各地区农村固定资产投资的产出弹性有增有减,整体上呈上升的趋势。东、中、西部产出弹性呈明显的差别,西部是加大农村固定资产投入的重点。     

马克思主义经典作家民主自治理论浅析

民主自治思想是马克思主义思想的重要组成部分,本文通过分析马克思主义经典作家民主自治思想产生的过程及主要内容,为现阶段中国特色社会主义民主自治建设提供了理论依据和实现路径。     

西方新资本结构理论综述

资本结构理论所研究的基本问题是企业资本结构与企业价值的关系。西方经济学界围绕这一基本问题展开了全面深入的研究,形成了许多不同的资本结构理论。20世纪70年代以来,随着信息经济学、委托代理理论等现代分析工具引入资本结构分析,资本结构理论研究获得了新的发展,一系列解释资本结构问题的新观点便应运而生,其流派众多,具有代表性的理论有以下几种:代理成本理论、信号传递理论和优序融资理论等。     

人口学特征与利率期限结构:老年社会平缓的收益率曲线

本文将刻画人口结构的生命周期模型引入消费-资本资产定价模型,考察人口结构对利率期限结构的影响。模型表明,人口结构及其家庭生命周期特征不仅决定利率水平,而且将通过人对债券期限的不同偏好,影响利率期限结构。少年人口占比对利率期限结构的影响为正,中年和老年人口占比的影响为负。相比少年人口,中老年人口更偏好长期债券,使长期收益率下降,期限结构的斜率更为平缓。基于全球数据的经验研究验证了这一结论。少年人口占比增加期限利差,中老年人口占比则起反向作用。因此,在年长的经济体中,期限利差更小,呈现更平缓的收益率曲线特征。在更换人口结构变量、期限利差变量、估计方法、赋权样本和处理遗漏变量后,结果表现稳健。本文从人口学视角拓宽了利率期限结构的决定因素,揭示了老年经济体可能面临一个平缓的收益率曲线,而这说明老龄化还可能通过抑制短期投机和促进长期投资来提高长期经济发展质量。
