铸铁的脆性分析

本文通过灰口铸铁的拉抻实验、压缩实验、扭转实验,用材料力学的分析方法,对灰口铸铁的极限应力,即拉伸极限应力σ_L,压缩极限应力σ_y 以及剪切极限应力τ的比较,得出脆性材料灰口铸铁的脆性特征为σ_L<τ<σ_y。     

论股权配给作用于宏观经济波动的机理

当宏观经济进入衰退阶段时,由于融资企业的股权配给,融资企业投资的边际破产成本上升,这将导致融资企业的投资下降,在投资乘数原理和加速数原理的相互作用下,会使宏观经济衰退更加严重,宏观经济陷入经济衰退与股权配给相互作用的恶性循环中,宏观经济衰退的程度会进一步加大。当宏观经济进入繁荣阶段时,具有与上述相类似的过程,会导致宏观经济持续过度繁荣。因此,股权配给是宏观经济波动的加速器。我国的现实是,从微观上看,上市公司具有强烈的股权融资偏好;从宏观上看,政府进行股权配给。两者的共同作用,使股权配给具有平抑宏观经济波动的功能。     

论中国政府预算管理改革的优先序--兼议绩效预算在中国的适用性

绩效预算是西方国家实践证明了的先进的预算管理模式。但绩效预算的实行需要社会相关制度环境的配套。中国目前尚不具备实施绩效预算的基本条件。中国预算制度改革的当务之急是建立控制取向的预算管理模式,解决财务合规性问题。待相关条件具备后,再选择绩效预算管理模式。

HOW CAN PUBLIC SPENDING HELP YOU GROW? AN EMPIRICAL ANALYSIS FOR DEVELOPING COUNTRIES

Although many studies indicate that both the level and composition of public spending are significant for economic growth, the results in the empirical literature are mixed. This paper suggests that the country sample selection and expenditure classification are important in explaining these conflicting results. The empirical analysis shows that the link between growth and public spending, especially its core component, is strong only for countries with macroeconomic stability and fast GDP per capita growth dynamics, which are also capable of using public funds for productive purposes.

Lumpy Investment and Corporate Tax Policy

In the presence of both convex and nonconvex capital adjustment costs in a dynamic general equilibrium model, corporate tax policy generates both intensive and extensive margin effects via the channel of marginal Q. Its impact is determined largely by the strength of the extensive margin effect, which, in turn, depends on the cross‐sectional distribution of firms. Depending on the initial distribution of firms, the economy displays asymmetric responses to tax changes. Moreover, an anticipated increase in the future investment tax credit reduces investment and adjustment rate initially.     

预算公开与廉洁政府关系的实证研究——基于OBI与CPI的相关性检测

预算公开与廉洁政府建设是学术界关注的热门话题,两者之间的关系更是其中的重点。2006、2008、2010与2012四个年度共同涉及的44个国家的预算公开指数与清廉指数的相关性检测表明,预算公开指数与清廉指数之间呈正相关关系,且基本属于高度相关,部分国家数据的不对称只是虚假背离。高度契合与虚假背离的背后起决定性作用的是成熟的民主政治,因此,预算公开推动廉洁政府建设需要以成熟的民主政治为前提和基石。     

Does personal background influence a finance minister to cook the books? An investigation of creative accounting in Swiss cantons

This article aims to identify the factors influencing the use of creative accounting in the public sector. Its distinctive feature is that it sheds light on creative accounting when used, not to hide public deficits, but to conceal surpluses. It especially explores the impact of the finance minister’s (FM)’s background on the phenomenon. We take advantage of the quasi-experimental settings of the Swiss cantons in which the financial management act sets out the possibility of implementing certain accounting gimmicks, including mainly additional ‘depreciation’ charges. These charges, which are depreciations in name only, enable the FM to artificially inflate expenses, thus increasing the deficit or reducing the surplus. Our panel data set of the 26 cantons over the period 1980–2012 includes a new data set of creative accounting and of 116 cantonal FMs. Our results indicate that the FMs cook the books irrespective of their personal or ideological background with the exception that trained economists tend to apply creative accounting more. Additionally, stringent fiscal rules urge FMs towards more surplus-hiding accounting.     

How should Engel's law be formulated?

Engel's law expresses a “negative stochastic association” of income and the proportion of income that is spent on food. However, there are many quite different notions of “negative stochastic association” and consequently there are different ways of defining Engel's law. We relate these different concepts to Engel's original statistical analysis and show that one must give credit to Engel for the first non-parametric statistical analysis of budget-data.
