基于交易或事项分类设计所得税会计债务法分析

本文从影响所得即净资产变动(基于经济收益观)的交易或事项出发,分析了时间性差异与暂时性差异的成因,探索利润表债务法与资产负债表债务法的设计思路。在此基础上,提出易于与税法衔接简化的资产负债表债务法——发生额资产负债表债务法。     

城区特征对房贷的影响

城区特征通过多种途径影响商业银行住房抵押贷款决策.商业银行可以根据城区特征判断一个城区的住房抵押贷款违约风险,进而确定对该城区的最低首付款比例或拒贷率.通过分析国外城区特征对商业银行住房抵押贷款决策的影响机制,联系我国实际情况,指出我国商业银行根据城区特征进行住房抵押贷款决策具有合理性,建议商业银行密切关注城区住房价格波动率,并建议政府限制中低收入城区商业银行的数量.     

上市公司股利分配理性化引导

本文认为,我国上市公司股利不分配股利的公司居多,且分配股利的以股票股利为主,现金股利的支付水平极低。这种非理性化股利政策对我国上市公司、投资者和资本市场均造成了极为不利的影响。为此,迫切需要尽快将上市公司的股利分配引导到理性状态。     

双寡头市场价格博弈分析——以我国国内成品油市场竞争主体为例

用博弈论分析市场行为是经济学的发展方向之一,本文从实证分析国内成品油市场中国石化与中国石油两大寡头的多种博弈情形及其收益变化过程,论证了在市场需求总量基本恒定状态下,双寡头市场价格博弈的纳什均衡解为(降价、降价),(不降价、不降价),前一种均衡解是双方在势均力敌、信息反馈充分的恶性竞争结果,后一种是在满足一定收益前提下的“双赢”策略。企业只有选择有别于竞争对手的非价格歧异性策略,形成自己的特色和优势,才能占领相应的市场,获得相应的经济效益。     

关于分配的若干有争议问题的看法

在研究我国现阶段分配问题时应该重视研究劳动所得,不应把重点放在非劳动收入上,劳动所得可以通过按劳分配获得,也可以通过按要素分配获得。生产要素按贡献参与分配的原则不等于按生产要素分配,生产要素按贡献参与分配原则中的“贡献”是指对使用价值生产的贡献,不能用分配工作的具体形式的某些共同性模糊不同分配方式的根本区别。     

粮食直接补贴面临的问题及对策研究

粮食直接补贴是我国2004年粮食流通体制改革的主要内容之一。直补经过四个阶段的探索和改革,在增加农民收入、保障国家粮食安全等方面取得良好效应。但改革是对政府、企业、农民三者之间利益关系的重大调整,在补贴方法、标准、资金等制度设计和操作过程中还存在很多需要研究的问题。因此,进一步深化改革,尤其是建立产销区间的直补资金转移机制非常重要。     

农民增收的极限约束与跨跃路径

从长期看,农民增收有两个极限性约束条件:一是收入增长速度不能高于或者相当于城市居民收入增长速度;二是农民收入增幅不能高于农村财富的增幅。但是农民收入又不能不维持大幅度的增长,否则会影响国民经济的增长,影响政治社会的稳定。要解决这对矛盾,必须通过农村内部挖潜,拓宽内源性增收空间;调整束缚增收的制度;寻找和扩大外源性增收渠道。     

The micro-foundations of intertemporal price discrimination

Summary. This paper investigates the optimality of intertemporal price discrimination for a durable-good monopoly in a model where infinitely-lived households face an intertemporal budget constraint, and consume both durable goods and non-durable goods. We prove that the optimal price of the durable good is not constant, and may decrease or increase over time. Some households may choose to purchase the durable good at a later date, and pay lower or higher prices, since the gain in discounted utility of consuming more of the non-durable good more than compensates for the loss in utility from delaying the consumption of the durable good.Received: 12 March 2004, Revised: 7 January 2005, JEL Classification Numbers: D40, D42, D91.I would like to thank C.D.

Money, Sex and Happiness: An Empirical Study

The links between income, sexual behavior and reported happiness are studied using recent data on a sample of 16,000 adult Americans. The paper finds that sexual activity enters strongly positively in happiness equations. Higher income does not buy more sex or more sexual partners. Married people have more sex than those who are single, divorced, widowed or separated. The happiness‐maximizing number of sexual partners in the previous year is calculated to be 1. Highly educated females tend to have fewer sexual partners. Homosexuality has no statistically significant effect on happiness.     

Taxation and household portfolio composition: US evidence from the 1980s and 1990s

This paper explores the relationship between household marginal income tax rates, the set of financial assets that households own, and the portfolio shares accounted for by each of these assets. It analyzes data from the 1983, 1989, 1992, 1995, and 1998 Surveys of Consumer Finances and develops a new algorithm for imputing federal marginal tax rates to households in these surveys. The empirical findings suggest that marginal tax rates have important effects on asset allocation decisions. The probability that a household owns tax-advantaged assets, such as tax-exempt bonds or assets held in tax-deferred accounts, is positively related to its tax rate on ordinary income. In addition, the portfolio share invested in corporate stock, which is taxed less heavily than interest bearing assets, is increasing in the household’s ordinary income tax rate. Holdings of heavily taxed assets, such as interest-bearing accounts, decline as a share of wealth as a household’s marginal tax rate increases.
