TIME‐CONSISTENT AND MARKET‐CONSISTENT EVALUATIONS

We consider evaluation methods for payoffs with an inherent financial risk as encountered for instance for portfolios held by pension funds and insurance companies. Pricing such payoffs in a way consistent to market prices typically involves combining actuarial techniques with methods from mathematical finance. We propose to extend standard actuarial principles by a new market‐consistent evaluation procedure which we call “two‐step market evaluation.” This procedure preserves the structure of standard evaluation techniques and has many other appealing properties. We give a complete axiomatic characterization for two‐step market evaluations. We show further that in a dynamic setting with continuous stock prices every evaluation which is time‐consistent and market‐consistent is a two‐step market evaluation. We also give characterization results and examples in terms of g‐expectations in a Brownian‐Poisson setting.     

The living commons of West Tyrol,Austria: Lessons for land policy and land administration

A right of commoners to pastures existed since the Early Middle Ages in Anglo-Saxon England and the European mainland, including Tyrol in Austria. Lowland commons institutions were largely dissolved by the 19th century; however, in the European Alps contiguous commons remain alive. Some two thousand alpine commons institutions are registered in the Tyrolean parcel cadaster and land registry. A specific study of West-Tyrolean commons (known as Agrargemeinschaft or AGMs), framed by Ostrom's design principles is presented. General lessons for land policy and land administration are extracted. An interview period was split between the Inn valley and the Ötztal. Roughly half are considered independent: others are regulated by the Tyrolean Agricultural Authority. Some AGMs hold the full bundle of land rights: others only hold pastoral and forestry rights. AGMs consisted either of a single cadastral parcel or several contiguous parcels. In the Inn valley villages the pastoral commons were owned by the municipalities, while in the researched Ötztal, AGMs are frequently the full owners of the commons. AGM membership ranges between 5 and 60 farm households. The number of livestock units pastured was in most cases stipulated in approved regulations. Alpine commons larger than 200 ha are also hunting-zones: revenue is collected from the lease of hunting rights. Most of the alpine commons are designated and used as ski-zones. Upper portions of two alpine commons in the Ötztal are state protected natural areas. The number of farms with pastoral rights is declining at District and State level. Key lessons for land policy and land administration include: Ostrom's design principles being a precondition rather than a panacea; commons institutions requiring one clear ownership party; both public and collective ownership producing success; publically owned commons requiring a local representative; small membership numbers being preferable; small shareholdings not being preferable; decentralized governance being beneficial; internal democratic elections being beneficial; internal boundary records being superfluous; explicit sanctions being superfluous; mixed economies being acceptable; and geography being a significant influence on the longevity of pastoral commons.

Feminism’s fourth wave: a research agenda for marketing and consumer research

Abstract

Three waves of feminism each reveal a very different relationship with marketing. This commentary considers these relationships in the light of what is now frequently being hailed as the fourth wave, a resurgence of feminism that is driven by younger women who harness the power of the Internet and social media to challenge gender inequity. The commentary looks at what distinguishes the fourth wave from its predecessors and highlights key areas in marketing and consumer research where feminist perspectives are sorely required.     

HOW COOPERATIVE ARE SAVINGS AND CREDIT COOPERATIVES IN DEVELOPING COUNTRIES?: AN ANALYSIS OF DATASETS FROM UGANDA

Building successful savings and credit cooperatives (SACCOs) that actually embody the cooperative principles is a challenge to development agencies. Although SACCOs form the majority of microfinance providers in many developing countries, the most recent literature on microfinance governance and performance has given little reference to the longstanding body of relevant cooperative literature. SACCO representation in microfinance datasets is biased. Drawing on so‐far unexploited datasets of Ugandan SACCOs and savings groups, this paper empirically analyses policy debate regarding SACCO‐ and savings group regulation. The findings point to the relevance of practically implementing the principle of ‘cooperation between cooperatives’ to ensure effective governance at SACCO level. Moreover, the paper introduces two new measures, based on members' savings and shares, which could become useful tools to track the application of cooperative principles in developing countries, and hence improve evidence‐based policy‐making for SACCOs.     

基于高光谱曲线的马铃薯与其他主要作物光谱差异性分析

[目的]文章以马铃薯关键生长期——结薯期为测量时点,以马铃薯和玉米、大豆、水稻为研究对象,开展高光谱曲线特征差异性研究。[方法]为更好地描述马铃薯与其他作物的光谱差异,创建高光谱反射率差异性指数、高光谱一阶导数差异性指数、高光谱红边幅值差异性指数、高光谱曲率差异性指数及高光谱植被指数差异性指数。[结果](1)马铃薯与玉米、大豆、水稻3种作物光谱曲线具有明显差异,马铃薯与玉米的反射率值在480nm附近蓝色波段位置差异最显著,差异性指数值为67.866%,与大豆、水稻的最大差异性指数值分别为49.068%、57.559%,均位于550nm附近绿色波峰位置;(2)作物光谱曲线经一阶导数变换运算,马铃薯与其他作物间的光谱差异被显著放大,在近红外波段放大程度最显著;(3)马铃薯与玉米、大豆、水稻高光谱曲率差异性指数最大值均位于波长750nm附近,差异性指数值分别为78.365%、63.471%、80.882%;(4)常用植被指数中,比值植被指数、增强型植被指数可显著区分马铃薯与玉米、大豆、水稻。[结论]差异性分析结果为农作物空间分布遥感识别提供了技术支撑。
