中国经济转型对老年人收入的影响

文章利用中国社会科学院经济研究所收入分配课题组1988年、1995年和2002年住户调查数据,探讨经济转型对于老年人收入的影响。文章描述了老年人供养体系的演变,分析了老年人收入的组成部分及收入不平等,并估计了老年人落入最高及最低3个收入十等分组的概率。文章分析表明,经济转型并没有对老年人的经济状况造成负面影响。     

A two-sample test for threshold crossing latent variables with application to valuation studies

Summary.  Contingent valuation researchers are often interested in a comparison of the underlying willingness-to-pay distributions in two independent studies. Since willingness to pay is not observable, traditional testing procedures for comparing distributions cannot be applied directly. The paper proposes a permutation test for this sort of comparison. The main distinguishing characteristic of the test proposed is that it does not rely on asymptotic approximations and facilitates the introduction of covariates. The permutation test is illustrated with the case of projects of investment for the improvement of two important Brazilian river basins.

Joint Control: A Discussion of Recent Research

The discrimination of the onset of joint control is an important interpretive tool in explaining matching behavior and other complex phenomena, but the difficulty of getting experimental control of all relevant variables stands in the way of a definitive experiment. The studies in the present issue of The Analysis of Verbal Behavior illustrate how modest experiments can take their place in a web of interpretation to make a strong case that joint control is a necessary element of such phenomena.     

IV Quantile Regression for Group‐Level Treatments,With an Application to the Distributional Effects of Trade

We present a methodology for estimating the distributional effects of an endogenous treatment that varies at the group level when there are group‐level unobservables, a quantile extension of Hausman and Taylor, 1981. Because of the presence of group‐level unobservables, standard quantile regression techniques are inconsistent in our setting even if the treatment is independent of unobservables. In contrast, our estimation technique is consistent as well as computationally simple, consisting of group‐by‐group quantile regression followed by two‐stage least squares. Using the Bahadur representation of quantile estimators, we derive weak conditions on the growth of the number of observations per group that are sufficient for consistency and asymptotic zero‐mean normality of our estimator. As in Hausman and Taylor, 1981, micro‐level covariates can be used as internal instruments for the endogenous group‐level treatment if they satisfy relevance and exogeneity conditions. Our approach applies to a broad range of settings including labor, public finance, industrial organization, urban economics, and development; we illustrate its usefulness with several such examples. Finally, an empirical application of our estimator finds that low‐wage earners in the United States from 1990 to 2007 were significantly more affected by increased Chinese import competition than high‐wage earners.     

A Contextual Approach to the Development of Self-regulatory Competencies: The Role of Maternal Unresponsivity and Toddlers' Negative Affect in Stressful Situations

A prospective study examined the effects of maternal unresponsivity and of toddlers’ own negative affect on the child's subsequent ability to use effective attentional control strategies in preschool. Maternal and child behaviors were measured in situations that varied in the level of stress to test the hypothesis that behaviors in high stress situations would be more diagnostic of children's subsequent self‐regulatory behavior. As predicted, both maternal unresponsivity and toddlers’ negative affect, particularly in a high stress as opposed to a low stress situation, predicted children's later use of ineffective attentional control strategies. Similarly, maternal disengagement that occurred contingent to toddlers’ distress predicted ineffective attentional control strategies whereas maternal disengagement in response to toddlers’ non‐distress behaviors did not. The findings supported the utility of a contextual approach to understanding the impact of maternal and child characteristics on the development of self‐regulatory skills.
