基于模糊评判分类控制法的流程式企业备件库存

从流程式企业备件备品库存管理的视角，利用模糊评判的方法对库存物资进行多标准的ABC分析，选择具有实际意义且有较强分辨性和代表性的统计指标，克服了传统库存分类法的片面性和局限性，对不同的库存备件相对于管理的重要性强弱作出明确的排序．得出具有实际经济意义的分类方案，同时根据最优分类结果，针对流程式企业库存物资的特性，着重考查在实际库存管理中存在的不合理之处，并对其进行更改。实行重点管理。

从“其他绿地”到“区域绿地”： 城市非建设用地下的绿地规划转型 与优化

新版《城市绿地分类标准》(CJJ/T 85—2017)以“区域绿地”代替“其他绿地”，这为城市非建设用地下绿地的保护利用提出了新的要求和目标。解读新标准指导下城市非建设用地中的绿地建设发展要求并进行科学合理的规划，是响应当前城市绿色发展新形势和满足人民日益增长的美好生活新需求所面临的重要课题之一。聚焦从“其他绿地”到“区域绿地”的分类调整，分析新标准下区域绿地的内涵和特征。以河北省承德市为例，结合城乡发展需求，阐述区域绿地规划的核心转型思路。并从目标、内容、方法和评价等方面，论述区域绿地设定下城市非建设用地中绿地规划的具体内容和方向。最后从空间政策、发展引导、部门合作和大众参与等方面，提出了规划实施保障优化的策略。以“区域绿地”的解读为源，聚焦当前城市建设用地内外绿地规划建设割裂的现状问题，提出区域绿地规划的转型优化措施和实践经验，以期为新时代中国城市绿色空间的拓展与优化提供参考。     

Toward a Phylogenetic Reconstruction of Organizational Life

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields such as organizational science, management science and economics and have long recognized that classification offers an approach for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities). However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity. This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics) are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic classification approach for inferring and representing the historical relationships underpinning organizational diversity. This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently, this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification of organizational diversity.

Strategic Price Discrimination in Compulsory Insurance Markets

This paper considers price discrimination when competing firms do not observe a customer’s type but only some other variable correlated to it. This is a typical situation in many insurance markets—such as motor insurance—where it is also often the case that insurance is compulsory. We characterise the equilibria and their welfare properties under various price regimes. We show that discrimination based on immutable characteristics such as gender is a dominant strategy, either when firms offer policies at a fixed price or when they charge according to some consumption variable that is correlated to costs. In the latter case, gender discrimination can be an outcome of strategic interaction alone in situations where it would not be adopted by a monopolist. Strategic price discrimination may also increase cross subsidies between types, contrary to expectations.JEL Classification No.: L13, G22

Option pricing in the presence of natural boundaries and a quadratic diffusion term

This paper uses a probabilistic change-of-numeraire technique to compute closed-form prices of European options to exchange one asset against another when the relative price of the underlying assets follows a diffusion process with natural boundaries and a quadratic diffusion coefficient. The paper shows in particular how to interpret the option price formula in terms of exercise probabilities which are calculated under the martingale measures associated with two specific numeraire portfolios. An application to the pricing of bond options and certain interest rate derivatives illustrates the main results.     

Calibrating an algorithm for estimating transactions from FXFX exchange rate quotes

In this paper we investigate the efficiency of a class of transaction-generating algorithms, originally suggested in Bollerslev and Domowitz (1993). Our comparison utilizes real transaction data recorded over Reuters D2000-2 electronic broking system for 7 h in June 1993 and transaction data generated from FXFX quotations over an identical period. Results suggest that, at this high-frequency data sampling, the performance of these transaction-generating algorithms is poor, with the most likely explanation of this outcome due to the high-frequency characteristics of FXFX spreads and quotation intensity.
