Management of hybrid organisations: a case study in retailing

Hybrid organisations present important theoretical and managerial opportunities. We examine a large Finnish multichain retail organisation in order to identify and understand the challenges of hybrids in a retailing context. We are especially interested in how these complex firms try to maintain a balance between the centralised corporate control and the local autonomy and initiative of their retailers. The governance forms and processes identified in the case organisation are discussed with the help of a proposed conceptual framework. We believe that the identified governance problems and practices in the three different retail chains and especially our recommendations will facilitate the understanding of retail hybrid organisations and the management of hybrids in general.     

仓储企业运营能力评价研究

文章通过综合考虑仓储企业的规模、效率,构建了一套仓储企业运营能力评价的指标体系,并针对这一复杂的多属性决策问题,提出了用逼近于理想解的排序方法(Technique for Order Preference by Similarity to Ideal Solution,TOPSIS)和层次分析法(AHP)结合的方法对仓储运营能力进行评价。     

基于综合集成赋权法的第三方物流服务商的选择

在构建物流服务商评价指标体系的基础上，提出了一种具有科学性、可操作性的基于主观赋权和客观赋权相结合的综合集成赋权法对第三方物流服务商进行综合评价。综合集成赋权法有效克服了现有评价方法的誉足，为评价物流服务商的综合水平提供了一种新的模型。     

基于熵的改进TOPSIS法在业务外包供应商选择中的应用

影响3PL选择的因素很多．其中交货提前期（T）、产品质量（Q）、变货可靠度（R）和产品价格（P）等4个因素是3PL选择的关键因素。本文就从这4个关键因素着手，从现代供应链管理要讲究战略的角度出发．引进基于熵的改进TOPSIS法，选择合适的3PL．和企业建立起长期的合作伙伴关系。

Do investors in Green Bond market pay a premium? Global evidence

We examine the pricing difference of Green Bonds (GB) and conventional bonds (CBs) in capital markets worldwide. Credit spread is used to observe whether investors would like to pay a premium for GBs over CBs. This study uses panel data regression with hybrid model to analyse daily observations over the period 2016 to 2017. We employ Option-Adjusted spread (OAS) to measure the credit spreads of bonds while controlling for bond specific, macroeconomic and global factors that influence the spread. With the hybrid model used in the panel data analysis, we were able to capture the fixed-effects of variables in a random effect model. We find that GBs are traded at a premium of 63 basis points (BPS), compared with a comparable corporate bond issue. We find that the green label provides issuers an incentive to raise funds through issuing GBs while providing investors an opportunity to diversify their investments returns. Our findings provide several implications to the major stakeholders driving the GB market to scale up the market to finance the required level of global green investment needs. We stress an urgent need to support the growth of the GB market to achieve sustainable development through mitigating climate change challenges.

Bioenergy Crop Production in the United States: Potential Quantities, Land Use Changes, and Economic Impacts on the Agricultural Sector

The U.S. Departments of Agriculture and Energyjointly analyzed the economic potential for,and impacts of, large-scale bioenergy cropproduction in the United States. Anagricultural sector model (POLYSYS) wasmodified to include three potential bioenergycrops (switchgrass, hybrid poplar, and willow). At farmgate prices of US $2.44/GJ, anestimated 17 million hectares of bioenergycrops, annually yielding 171 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes highproductivity management practices are permittedon Conservation Reserve Program lands. Traditional crops prices are estimated toincrease 9 to 14 percent above baseline pricesand farm income increases annually by US $6.0billion above baseline.At farmgate prices of US $1.83/GJ, anestimated 7.9 million hectares of bioenergycrops, annually yielding 55 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes managementpractices intended to achieve highenvironmental benefits on Conservation ReserveProgram lands. Traditional crops prices areestimated to increase 4 to 9 percent abovebaseline prices and farm income increasesannually by US $2.8 billion above baseline.     

Hybrid Inflation-Price-Level Targeting in an Economy With Output Persistence

This paper investigates hybrid inflation‐price‐level targeting (HT), employing a Phillips curve with output persistence. By HT we mean that a central bank targets a weighted average of the optimal inflation rate and its corresponding price level. The analysis shows that if output is persistent to some extent, it is desirable to adopt HT because, relative to the case of alternative regimes such as inflation targeting (IT) and price‐level targeting (PT), it will reduce the variability of inflation and thereby social loss. In addition, it is shown that the optimal hybrid‐type target is uniquely determined according to the degree of persistence in output.
