CONTRIBUTIONS DU MOUVEMENT COOPÉRATIF AU CONTRLE DE L'ÉCONOMIE ET À LA COHÉSION SOCIALE DU QUÉBEC

RESUME*: Selon l'auteur, le mouvement coopératif du Québec s'est développé en trois grandes étapes:—1900–1920;-1940–1960;-1975–1985, sous l'impulsion de leaders proches des besoins populaires. Prětres, intellectuels, membres de professions libérales, leaders syndicaux et communautaires liés par le nationalistie québécois, vont permettre au mouvement coopératif de se donner un enracinement populaire exceptionnel et des résultats économiques impressionnants.

我国通胀与经济增长放缓福利 成本的比较研究

经济理论和实践经验通常认为我国经济增长放缓的福利成本远高于通货膨胀的福利成本,因而“保增长”的重要性远高于“防通胀”。本文认为这一判断已经不再适用于我国当前情况,核心原因是当前家庭的财产积累水平较以往有了大幅度提高,通胀将通过财产再分配效应造成严重的社会福利损失。经过计算发现：在各组参数设定下,5%的通胀和经济增速下滑一个百分点所造成的社会总福利成本（对消费的补偿比例）分别平均是18%和59%;通胀福利成本与增长放缓福利成本之比平均为329%,相比之下,在不考虑财产再分配效应的计算方法中,该比例仅为约16%。这说明在中长期“保增长”和“防通胀”都具有重要的社会福利意义,因此宏观调控应该将二者都作为重要的政策目标。     

GROWTH IN THE SHADOWS: EFFECT OF THE SHADOW ECONOMY ON U.S. ECONOMIC GROWTH OVER MORE THAN A CENTURY

Taking a long‐term look at U.S. economic growth over 1870–2014, this paper focuses on the spillovers from the shadow or the unofficial economy to growth in the official sector. Shadow activities might spur or retard economic growth depending on their interactions with the formal sector and impacts on the provision of public goods. Nesting the analysis in a standard neoclassical growth model, we use a relatively new time series technique to estimate the short‐run dynamics and long‐run relationship between economic growth and its determinants. Results suggest that prior to World War II (WWII) the shadow economy had a negative effect on economic growth; however, post‐WWII the shadow economy was beneficial for growth. The sanding effect of the shadow economy in the earlier period is especially robust to alternate considerations of possible endogeneity and an alternate set of growth determinants.

经济周期中就业波动研究新进展

本文通过梳理国外最新研究文献,我们发现:(1)经济周期中就业波动存在滞后与回滞现象。(2)经济周期中的就业波动形态在不同部门间存在巨大差异。(3)经济周期的不同冲击源对就业波动有着迥异的影响。     

PRICE AND QUANTITY COMPETITION IN A UNIONISED MIXED DUOPOLY: THE CASES OF SUBSTITUTES AND COMPLEMENTS*

We investigate a differentiated mixed duopoly in which private and public firms can choose to strategically set prices or quantities when unions are present. For the case of a unionised mixed duopoly, there exists a dominant strategy only for the public firm that chooses Bertrand competition irrespective of whether the goods are substitutes or complements; there is no dominant strategy for a private firm. Thus, we show that regardless of the nature of goods, social welfare under Bertrand competition is always determined in equilibrium, wherein Bertrand competition entails higher social welfare than Cournot competition. Moreover, our main results hold irrespective of the nature of goods, with the exception that when a sufficiently large parameter of complements is employed, the ranking of a private firm's profit is not reversed, which is in contrast to the standard findings.     

核心高管特征与公司成长性关系研究——基于中国沪深两市上市公司数据的经验研究

本文以我国沪深两市2004—2006年的上市公司为样本,从核心高级管理人员的人力资本特征视角,对高管特征与上市公司成长性的关系进行了经验检验。本文发现,在其他条件不变的情况下,上市公司成长性与核心高管的平均年龄、平均任职时间显著相关,而与核心高管平均学历的相关性不显著。进一步的研究还表明,在国有控股公司和非国有控股公司中,核心高管特征与公司成长性的关系具有显著差异。本文的研究有助于深化认知人力资本特征在公司发展过程中的重要地位,对强化核心高管遴选、完善人力资源管理具有积极的借鉴意义。     

都市近郊特色古镇休闲旅游开发研究——以长沙靖港古镇为例

目前古镇旅游较少地触及古村镇旅游发展的内在机理和演变规律,研究的案例样本集中于江南古镇、皖南古镇和川西古镇等几个地域。以湖南长沙靖港古镇为例,探讨位于城郊,区域文化厚重,自然风光优美的都市特色古镇休闲旅游形成、开发的背景、条件和途径。     

QUALITY DIFFERENTIATION,WELFARE, AND THE MODE OF COMPETITION IN A VERTICALLY DIFFERENTIATED PRODUCT MARKET: A NOTE*

We analyse the implications of quality differences in a vertically differentiated product market for social welfare by employing an endogenous quality choice model. We find that in of Bertrand and Cournot duopolies, the degree of quality differentiation at equilibrium in an unregulated market is larger or smaller, respectively, than that of the socially second‐best optimum. This implies that a reduction in quality difference, respectively, increases or decreases social welfare in the case of Bertrand or Cournot duopolies.     

ETHNIC AND GENDER DIFFERENCES IN INTERGENERATIONAL MOBILITY: A STUDY OF 26-YEAR-OLDS IN THE USA

This paper uses the traditional income framework and a non‐monetary framework to estimate intergenerational mobility in economic status for a sample of 26‐year‐old whites, blacks and Hispanics in the USA using data from the first and fifth sweeps of the National Educational Longitudinal Study (1988 and 2000). Intergenerational income mobility is found to be greater for males than for females, although there are differences between whites, blacks and Hispanics. Transition probabilities indicate that Hispanics are the most upwardly mobile in terms of educational attainment and occupational status. Ordered logits are used to estimate the impact of parental education and occupation on educational and occupational outcomes.     

农户经济收入与经营行为研究--来自黑河流域中游地区的调查

农户是农村经济活动的行为主体，是农业生产中最基本的决策单元。因此，农户经济及其经营行为与持续农业及农村经济发展关系密切。依据黑河流域中游地区农户抽样调查的统计数据，分析了近5年来农户收入的现状和趋势，在此基础上总结了当前农户经营行为的特点，并运用经济学模型对农户经营行为及其对农户收入的影响进行了理论分析。最后根据得出的结论，对政府部门制定农业政策与农村体制提出了一些建议。
