隐性教育资源特点及其在高校思政教育中的功能分析

运用传统教学资源——显性教育资源(教材、教参、时事政策、报告等)进行高校思想政治理论教育已严重影响教育效果。面对这种情况,笔者通过探讨隐性教育资源的特点及其在高校思政教育中的功能,以促使广大思政教育者在高校实际教育工作中能重视隐性教育资源的教育功能,从而积极主动开发和运用隐性教育资源达到提高高校思政教育的实效性。

A characterization of exact non-atomic market games

Continuous exact non-atomic games are naturally associated to certain operators between Banach spaces. It thus makes sense to study games by means of the corresponding operators. We characterize non-atomic exact market games in terms of the properties of the associated operators. We also prove a separation theorem for weak compact sets of countably additive non-atomic measures, which is of independent interest.

South Africa's economics of education: A stocktaking and an agenda for the way forward

This paper reviews some of the existing economics of education literature from the perspective of South Africa's education policymaking needs. It also puts forward a suggested research agenda for future work. The review is arranged according to five areas of research: rates of return, production functions, teacher incentives, benefit incidence analysis and cross-country comparisons. Production functions, especially if translated to cost-effectiveness models, can point to important policy solutions. Teacher incentives is a policy area that is in need of a better theoretical and empirical basis. Rates of return are difficult for policymakers to interpret, but suggest a need for a qualification below the Grade 12 level. While benefit incidence analysis can demonstrate large improvements in the equity of public financing, cross-country comparisons reveal that not only is the distribution of schooling outcomes particularly unequal, on average it is well below what the country's level of development would predict.     

Non-convex Technologies and Cost Functions: Definitions,Duality and Nonparametric Tests of Convexity

This contribution is the first systematic attempt to develop a series of nonparametric, deterministic technologies and cost functions without maintaining convexity. Specifically, we introduce returns to scale assumptions into an existing non-convex technology and, dual to these technologies, define non-convex cost functions that are never lower than their convex counterparts. Both non-convex technologies and cost functions (total, ray-average and marginal) are characterized by closed form expressions. Furthermore, a local duality result is established between a local cost function and the input distance function. Finally, nonparametric goodness-of-fit tests for convexity are developed as a first step towards making it a statistically testable hypothesis. An erratum to this article is available at .     

Discounting long run average growth in stochastic dynamic programs

Summary. Finding solutions to the Bellman equation often relies on restrictive boundedness assumptions. In this paper we develop a method of proof that allows to dispense with the assumption that returns are bounded from above. In applications our assumptions only imply that long run average (expected) growth is sufficiently discounted, in sharp contrast with classical assumptions either absolutely bounding growth or bounding each period (instead of long run) maximum (instead of average) growth. We discuss our work in relation to the literature and provide several examples.
