用人单位对员工权利限制的正当性标准探讨

用人单位对员工权利的限制,有其存在的合理性和必然性,法律应对此予以认可。同时法律应确立相应的权利限制 的正当性标准,以对用人单位限制员工权利的行为加以必要的规范和指导。对劳动者实行倾斜立法,只能是立法的技巧,而不 能是立法的理念,法律必须兼顾用人单位的经营利益。     

Statistical Disclosure Risk: Separating Potential and Harm

Statistical agencies are keen to devise ways to provide research access to data while protecting confidentiality. Although methods of statistical disclosure risk assessment are now well established in the statistical science literature, the integration of these methods by agencies into a general scientific basis for their practice still proves difficult. This paper seeks to review and clarify the role of statistical science in the conceptual foundations of disclosure risk assessment in an agency’s decision making. Disclosure risk is broken down into disclosure potential, a measure of the ability to achieve true disclosure, and disclosure harm. It is argued that statistical science is most suited to assessing the former. A framework for this assessment is presented. The paper argues that the intruder’s decision making and behaviour may be separated from this framework, provided appropriate account is taken of the nature of potential intruder attacks in the definition of disclosure potential.     

Regime switching in stochastic models of commodity prices: An application to an optimal tree harvesting problem

This paper investigates whether a regime switching model of stochastic lumber prices is better for the analysis of optimal harvesting problems in forestry than a more traditional single regime model. Prices of lumber derivatives are used to calibrate a regime switching model, with each of two regimes characterized by a different mean reverting process. A single regime, mean reverting process is also calibrated. The value of a representative stand of trees and optimal harvesting prices are determined by specifying a Hamilton-Jacobi-Bellman Variational Inequality, which is solved for both pricing models using a implicit finite difference approach. The regime switching model is found to more closely match the behavior of futures prices than the single regime model. In addition, analysis of a tree harvesting problem indicates significant differences in terms of land value and optimal harvest thresholds between the regime switching and single regime models.     

Regulation and Evolution of Compliance in Common Pool Resources

The evolution of compliance with regulation and the evolution of a CPR stock are modeled jointly in a setup where replicator dynamics describing compliance with harvesting rules are combined with resource stock dynamics. This evolutionary approach suggests that in long‐run equilibrium, coexistence of both cooperative and non‐cooperative rules is possible under regulation. Stock effects on profits and a certain structure of auditing probabilities could imply the emergence of a limit cycle in areas of low stock levels, as an equilibrium outcome. It might be easier for the regulator to obtain full compliance under precommitment to fixed auditing probabilities.     

Developers and farmers intertwining interventions: the case of rainwater harvesting and food-for-work in Degua Temben,Tigray, Ethiopia

Understanding the objectives, strategies and actions of the different actors that play a role in the implementation of rural development programmes is a key to explaining the latter's success and sustainability. Based on in-depth anthropological fieldwork and from an actor perspective this paper shows how the Rainwater Harvesting Pond Programme (RHPP) and the public work component of the Productive Safety Net Programme (PSNP) work out in practice in one district of the Tigray region in Ethiopia. Developers and farmers turn the two essentially unrelated rural development programmes into practically intertwined interventions, which leads to an undesirable set of outcomes. The RHPP's participants, who are conceived of as willing to improve, are favoured above other candidates for employment in the PSNP, which farmers compete for. Developers' and farmers' moves and countermoves result in targeting errors in the PSNP and in farmers massively constructing rainwater harvesting ponds, the large majority of which fail because farmers do not aspire to make them succeed, but merely see them as a stepping stone to employment in the PSNP. In addition both groups' perception of each other is affected. Our observations challenge prevailing interpretations of the effects of development interventions on Tigrayan people's livelihoods.
