Demand‐side housing policy in Costa Rica: a response to the housing deficit

The purpose of this study was to establish what the housing needs of Costa Rica are and to assess what policies have been implemented to respond to their housing deficit. In order to answer these questions, a combined methodology consisting of primary and secondary data was used. Using open‐ended questions and a topic schedule, face‐to‐face interviews with Costa Rican housing authorities were conducted at the interviewee's work place in Costa Rica in May 2003. The most recent secondary data available in the country was used to compute the housing deficit and to study the effects of demographics on current housing needs. Sources of the secondary data were the Costa Rica Ministry of Housing and Human Settlements, and the National Institute of Statistics and Census. The Costa Rican government has made great progress in reforming the housing finance system in order to meet the housing demand of its citizens. In 2002, Costa Rica had a 75.6% home ownership rate. Yet, even in light of the housing system's current success, many social, economic and political barriers threaten to undermine its accomplishments and the peoples’ ability to obtain safe and affordable housing. The paper considers the strengths and weaknesses of the current housing finance system as well as the government strategies for addressing difficulties.

人的全面发展的经济保证--以马克思的人的全面发展理论试解"重建个人所有制"之谜

马克思在《资本论》中提出了在未来社会“重新建立个人所有制”的设想，成为马克思留给后人的历史之迷。笔者根据马克思的人的全面发展理论并通过分析其早年的“劳动异化理论”认为：“个人所有制”是消灭私有制、实现公有制的真实体现。“重新建立个人所有制”是指社会财富由私有制条件下的剥削被剥削的“现状”向“应当”由劳动者自己享有的现实“回归”，是实现人的全面发展的经济保证。     

上市公司“既分又配”现象的实证分析

在我国上市公司“既分又配”的现象普遍存在，这种有悖于一般财务政策的行为为什么会存在呢？国内的学者很少进行研究，本文就在已经分红的基础上从影响“既分又配”股利政策的因素人手，通过实证分析，发现仅有资产规模、净资产盈利率、股市行情等对“既分又配”有明显的影响，而且影响的方向与我们预期的相同。但是，企业的成长能力、股权自由流量的影响并没有得到实证分析的证明，有待于进一步研究。     

Simulation driven inferences for multiply imputed longitudinal datasets*

In this article, we demonstrate by simulations that rich imputation models for incomplete longitudinal datasets produce more calibrated estimates in terms of reduced bias and higher coverage rates without duly deflating the efficiency. We argue that the use of supplementary variables that are thought to be potential causes or correlates of missingness or outcomes in the imputation process may lead to better inferential results in comparison to simpler imputation models. The liberal use of these variables is recommended as opposed to the conservative strategy.     

世界遗产:公共产权的转移与约束

世界遗产是具有公共产权性质的特殊资源，应由国家进行永久性保护。但由于目前我国文物保护经费的不足，以及现行体制把世界遗产的管理权分散到地方政府各部门，在获得保护经费及旅游利益的驱动下，部分遗产地出现了过度开发现象，导致世界遗产保护区的城市化与商业化．出现保护与开发矛盾的根本原因，在于世界遗产公共产权私人化趋向，导致其外部性的增强．可能的解决途径是世界遗产公共产权由中央或地方的国家单一部门管理，以实现产权的硬约束，并且建立旅游收益与保护资金之间，政府与旅游企业之间的平衡。

建立我国商业银行外部审计制度的构想

商业银行外部审计因受托责任的发生、发展而产生和发展。实践证明，商业银行外部审计，可以从根本上改善商业银行内部管理和控制的有效性，提高金融监管当局的监管效率。加入WTO后，我国商业银行在面对强大的外部竞争者的同时，风险管理及监管水平低的问题也日趋凸显。因此，我们认为在提高商业银行自身经营管理水平、风险控制能力以及中央银行监管效率的同时，应从制度安排入手建立中国的商业银行外部审计制度。     

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.
