Technical note: Finite-time regret analysis of Kiefer-Wolfowitz stochastic approximation algorithm and nonparametric multi-product dynamic pricing with unknown demand

We consider the problem of nonparametric multi-product dynamic pricing with unknown demand and show that the problem may be formulated as an online model-free stochastic program, which can be solved by the classical Kiefer-Wolfowitz stochastic approximation (KWSA) algorithm. We prove that the expected cumulative regret of the KWSA algorithm is bounded above by where κ₁, κ₂ are positive constants and T is the number of periods for any T = 1, 2, … . Therefore, the regret of the KWSA algorithm grows in the order of , which achieves the lower bounds known for parametric dynamic pricing problems and shows that the nonparametric problems are not necessarily more difficult to solve than the parametric ones. Numerical experiments further demonstrate the effectiveness and efficiency of our proposed KW pricing policy by comparing with some pricing policies in the literature.     

反腐败中“保护主义”现象的原因及其治理

在我国的反腐败斗争中,有一种保护主义现象。它来自社会各个方面,存在于人们的思想感情、政治倾向及权力运作等各个领域,是影响反腐败斗争深入开展的严重障碍。文章从我国当前反腐败斗争的社会现实出发,着重列举了“保护主义”在党员、干部思想行为上的主要表现及其原因,提出了治理办法：要教育广大党员、干部进一步加强建设有中国特色的社会主义理论和社会主义市场经济理论的学习,确立社会主义的改革开放观;要把清除“保护主义”影响的工作纳入源头治理的范畴,实行综合治理;要切实落实党风廉政建设责任制,增强各级领导干部反腐败的责任意识,加大党内和群众监督的力度;要建章立制,加强对党风廉政建设工作的检查和考核。

How old is too old? An economic approach to replacing military aircraft

The US Air Force is asking when to replace its aging aircraft. We develop a framework to identify economically optimal replacement strategies that recognizes cost trade-offs and incorporates age effects. We also preview a stochastic methodology. We use the framework to identify an optimal strategy, defined by the replacement age, for a generic fleet and conduct a sensitivity analysis. Quantitative illustrations show that the range of strategies that provides close-to-optimal outcomes widens as the operating and support (O&S) cost growth rate decreases and the ratio of the acquisition price to the initial O&S cost increases. A wider range implies more decision-making leeway.     

Security sector stabilisation in counterinsurgency operations: the case of Afghanistan

This article argues that the debate on security sector reform (SSR) needs to be taken further by taking into consideration the fact that, even though the SSR concept was not originally developed as an element in stabilising states undergoing an insurgency, it is very much being used for exactly that. When conducting counterinsurgency with a focus on the creation of stability, the baseline will ultimately have to be security sector stabilisation (SSS) as a precondition for complete SSR implementation. However, the two must be connected to avoid them undermining each other. This is important if a comprehensive approach to programme implementation and especially sustainability is to guide the programme, and not just isolated ‘train and equip’ stand-alone projects that do not solve either the initial need for stabilisation or the long-term need for accountable security forces. Currently, in Afghanistan the surge for security by the international military is in danger of overtaking the other elements of the SSR, thereby undermining the primary end state and thus risking laying the wrong foundation for the long-term process of SSR.
