We report evidence from an experiment where an employer selects one of two workers to perform a task for a fixed compensation. Workers differ in their ability. The employer’s payoff depends on the worker’s ability and on a non-contractible effort that the worker exerts once employed. We find that selected workers exert an effort higher than the minimum enforceable one. When the employers can send a free-text form message to the selected worker, workers with low ability exert significantly higher effort than the workers with high ability. The difference in effort overcompensates the difference in ability. 相似文献

在美丽的河南云台山区,有一个非常吸引人的地方,寒假期间,我在那里度过了整整一个月的时间。虽然身处另一个省份,这里却与山东有着紧密的联系。2009年,一个很有名的功夫老师来到这里,建立了一所新的学校。如今,这所学校吸引了来自全世界的200名学徒。这个老师就是释延林。 相似文献

战国后期,山东思想史上有一位伟大的人物叫苟子,他曾经说过两个关于风俗习惯的既有趣又恰当的观点。“干越夷骆之子,生而同声,长而异俗,教使之然也。”和“譬之,越人安越,楚人安楚,君子安雅;是非知能材性然也,是注错习俗之节异也。”无论在中国还是在我的家乡苏格兰,想起与庆祝新年有关的不同传统和风俗,苟子的这些观点总是很中肯。 相似文献

This paper presents an early warning system as a set of multi‐period forecasts of indicators of tail real and financial risks obtained using a large database of monthly US data for the period 1972:1–2014:12. Pseudo‐real‐time forecasts are generated from: (a) sets of autoregressive and factor‐augmented vector autoregressions (VARs), and (b) sets of autoregressive and factor‐augmented quantile projections. Our key finding is that forecasts obtained with AR and factor‐augmented VAR forecasts significantly underestimate tail risks, while quantile projections deliver fairly accurate forecasts and reliable early warning signals for tail real and financial risks up to a 1‐year horizon.

This paper analyzes the role of Uruguay's sharp minimum wage increases after 2004 amidst the country's slight wage inequality decrease. We found that the minimum wage increase has contributed to the reduction of wage inequality for formal workers mainly. However, we also found a negative impact on employment outside the capital city, Montevideo, and observed a reduction in working hours. These results raise doubts about the effectiveness of minimum wage as a redistribution instrument in developing countries. 相似文献

Most psychometric studies of risk perception have used data that have been averaged over participants prior to analysis. Such aggregation obscures variation among participants and inflates the magnitude of relationships between psychometric dimensions and dependent variables such as overall riskiness. However, most studies that have not averaged data over participants have also shifted the focus of analysis from differences among hazards to differences among participants. Hence, it is unclear whether observed reductions in the explanatory power of psychometric dimensions result from the change in the level of analysis or from the change in the focus of analysis. Following Willis et al.'s (2005) analysis of ecological risk perceptions, we unconfound these two variables in a study of risk perceptions in Santiago, Chile, although we use more traditional hazards, attributes, and statistical procedures. Results confirm that psychometric dimensions explain less variation in judgments of riskiness and acceptability at the disaggregate level than at the aggregate level. However, they also explain less variation when the focus of analysis is differences among participants rather than differences among hazards. These two effects appear to be similar in magnitude. A simple hybrid analysis economically represents variation among participants' judgments of hazards' riskiness by relating those judgments to a common set of psychometric dimensions from a traditional aggregate‐level analysis. 相似文献
