折旧方法对盈亏平衡点的影响分析

分析了折旧方法对静态盈亏平衡点及动态盈亏平衡点的影响，结果表明，不同的折旧方法对盈亏平衡点的影响很大。     

固定资产动态折旧的分类模型与通用模型构建

文章参照固定资产静态折旧的几种典型模型,构建了直线动态折旧模型、折旧基数变化情况下的加速动态折旧模型、折旧率变化情况下的加速动态折旧模型,分别根据各种折旧模型各自折旧额的内在规律性进行建模,比较好地实现了从静态折旧模型向动态折旧模型的转化.在此基础上,本文试图去寻找各种动态折旧模型中各期折旧额的共同规律,进而建立起固定资产动态折旧的通用模型,以供企业根据自己的实际情况代入相应初始条件直接套用固定资产动态折旧的通用模型,方便地计算固定资产各期的动态折旧金额.     

上市公司利用减值准备进行盈余管理的实证研究--以吉林省上市公司为例

上市公司于2001年1月1日起开始执行新的企业会计制度,新的会计制度与原会计制度相比最显著的变化就是在原来四项资产减值准备计提的基础上又增加四项减值准备。这八项减值准备的计提,充分体现了谨慎性原则对历史成本原则的修正,目的是为了挤出上市公司资产中的水分,保护所有者和债权人的利益,从而化解其投资风险。通过对吉林省上市公司八项资产减值准备计提情况的分析,可以反映出吉林省上市公司利用减值准备进行盈余管理的实际情况。

Capital maintenance and depreciation over the business cycle

This paper develops and estimates a stochastic general equilibrium model with capital maintenance, which affects endogenously the depreciation rate of capital. The estimate of maintenance series is found to track survey-based measures for Canada quite closely and to generate the procyclical pattern of maintenance observed in the data. We use our model estimates to infer the time profile of equipment capital depreciation in Canadian and US manufacturing. The depreciation rate is estimated to be volatile and highly procyclical in both countries.     

Depreciation of Business R&D Capital

We develop a forward-looking profit model to estimate the depreciation rates of business R&D capital. By using U.S. government data between 1987 and 2007, and the newly developed model, we estimate both constant and time-varying industry-specific R&D depreciation rates. The results comprise a set of R&D depreciation rates for major U.S. high-tech industries. They align with the main conclusions from recent studies that the rates are in general higher than the traditionally assumed 15 percent and vary across industries. The relative ranking of the constant R&D depreciation rates among industries is consistent with industry observations and the industry-specific time-varying rates are informative about the dynamics of technological change and the levels of competition across industries. Lastly, we also present a cross-country comparison of the R&D depreciation rates between the U.S. and Japan, and find that the results reflect the relative technological competitiveness in key industries.     

A sectoral analysis of the financial instability hypothesis

Hyman Minsky's Financial Instability Hypothesis (FIH) is applied to various North American Industrial Classification System (NAICS) industry groups, and it is found that some sectors develop much more closely in accordance with the FIH than others. Minsky categorized firms based on the relationship between cash flow and debt service requirements: hedge finance units, whose operating revenues are adequate to service current interest and principal on their debt; speculative finance units, which can meet interest payments but cannot pay down principal; and Ponzi finance units, which cannot meet current interest payments. The FIH is related to, as well as supportive of, Austrian Business Cycle (ABC) theory, because interest rates are negatively correlated with the proportion and market value of speculative firms in several sectors.     

固定资产折旧及其政策选择

折旧作为再生产过程中的经济现象,其本质属性是固定资产损耗价值的周转过程,包括固定资产价值的损耗、转移和补偿。在此理论基础上,企业折旧政策的选择应该是既能考虑补偿损耗、企业扩张和纳税延期的要求,又能满足维护和提高企业的市场价值的要求。折旧政策选择可采用以下策略,即企业盈利水平不断提高时,可以选择长时间慢速折旧和长时间平均折旧;企业盈利水平呈下降趋势或先高后低时,则可以选择短时间快速折旧和长时间快速折旧。     

美元贬值下的人民币汇率制度选择

2002年以来，美元汇率持续贬值，对世界经济及我国经济产生了重大影响。对人民币实质汇率水平也产生了重大影响，人民币实质汇率水平的决定除了取决于美元趋势外，主要还受国内宏观经济的变化趋势、国际收支的变化趋势的影响。为此，我国应在保持人民币汇率稳定前提下，尽快培育和完善人民币汇率市场，形成机制，增强汇率杠杆对经济的调节作用，推动外汇市场的管理创新，增强交易主体的竞争力。
