有毒有害食品事件屡次发生的原因分析

人民群众餐桌安全、生命健康安全是维护社会稳定的头等大事之一,关乎群众切身利益、群众反映强烈的有毒有害食品已引起政府和全社会的高度重视。本文针对若干有毒有害食品事件进行分析,结果表明导致这类事件屡次发生的原因主要有:①政府和相关职能部门的管理和监督缺乏力度,至今还没有建立完全可靠的食品安全控制体系。②一些商家经营的规范和诚信责任不强,一些员工职业道德缺失和食品安全知识匮乏。③消费者维护食品安全意识薄弱。只有政府相关职能部门切实实施有效管理和监督,食品企业切实履行经营规范、诚信责任和员工职业道德教育及食品安全知识的培训,所有消费者切实提高认识和识别能力来维护食品安全,只有这样才能使人们的饮食健康能够得到保障。     

Lags and Leads in Life Satisfaction in Korea: When Gender Matters

Using detailed longitudinal data from the Korean Labor and Income Panel Study (KLIPS) from 1998 to 2008, this paper finds significant gender differences in impacts as well as adaptation patterns to major life and labor market events in Korea. Men remain on a higher happiness level throughout marriage, while women return to their baseline happiness within only two years. Consequently, men suffer more from divorce and the death of a spouse. This marital gender happiness gap is equivalent to a (husband only) increase of annual per capita household income of approximately US$17,800. The study further finds that men suffer more from unemployment. Results are robust to the inclusion of multiple simultaneous events and the use of different estimators.

Hyperbolic Discounting,Borrowing Aversion and Debt Holding

Analysis of an original Internet‐based survey reveals that debt holding is related to time discounting through: (i) present bias, measured by the degree of declining impatience in the generalized hyperbolic discount function; (ii) borrowing aversion, captured by a sign effect in that future losses are discounted at lower rates than future gains; and (iii) impatience, measured by the overall discount rate. Hyperbolic respondents are classified naïve if their answers reveal them to be time‐inconsistent procrastinators, and otherwise sophisticated. Naïve respondents with more steeply declining impatience are more likely to be debtors. The sign effect relates negatively to borrowing. Survey responses indicative of high or declining impatience are associated with credit card borrowing and other overborrowing indicators.     

Profiting from innovations: the role of new game strategies in the case of Lipitor of the US pharmaceutical industry

In exploring why innovators often do not profit from their innovations, researchers concentrate on innovators versus imitators and the extent to which owners of complementary assets capture profits from innovations. The literature provides scant attention to factors that sap profits from innovations. This paper argues that an innovator's positioning vis‐à‐vis customers, suppliers, complementors, and other co‐opetitors plays a critical role in the innovator's profitability. The article explores how an innovator can use new game strategies to better positioning, thus capturing rents from innovations and enabling further innovations in the future. The study examines the case of Lipitor, one of the world's best‐selling drug, to illustrate how positioning can play in a firm's ability to profit from its innovations.     

试论税收调节收入分配的局限性以及教育问题的引入

改革开放以来中国国民经济的持续快速发展，促进了城乡居民收入总体的不断提高，客观上也带来了经济利益在不同利益群体间的重新调整和分配及社会收入分层的加剧，居民收入差距在城乡、行业、地区之间的扩大，逐步成为现阶段收入分配领域的焦点问题。一些人把我国贫富差距拉大的原因归咎于没有建立起一套完善的税制，致使税收的调控功能没有有效发挥出来。笔者认为，这种说法是有失偏颇的。
