Value chain finance(VCF)represents the aligning and structuring of finance within a value chain or as a result of its existence.Given the growing need to explore innovative approaches to rural and agricultural finance in Nigeria,such financing solutions have become imperative.However,few studies on the ex-ante impact of financing innovations exist.Therefore,to ascertain the benefits derivable from VCF,this paper analyzes the potential impact of VCF on plantain production in Nigeria.The expected benefits are estimated based on the economic surplus model,using the Dynamic Research Evaluation for Management(DREAM)software.Results from a 25-year simulation period at a 15%discount rate and an innovation cost of USD 1,300,000,show that,in the least optimistic scenario,the economy is expected to have an overall net gain(economic surplus)of USD 3256,800,with a net present value of USD 3406,880,benefit-cost ratio of 3.83,and an internal rate of return or break-even discount rate of 36.80%.These results indicate the positive impact of VCF,measured in terms of net present value and net benefit,expressed as producer and consumer surplus.This suggests VCF is a viable and beneficial financing innovation for food production in Nigeria.Finally,it is recommended that a value chain financing agency be established to make finance available to farmers to boost food production in Nigeria. 展开更多

本文使用SVAR方法将中国短期名义利率拆分成预期通货膨胀率和Ex-ante实际利率两部分。为了解决SVAR模型识别条件不足的问题,本文使用BQ方法,认为实际利率冲击对名义利率没有长期影响,名义利率的长期波动全部来源于预期通货膨胀率的波动... 本文使用SVAR方法将中国短期名义利率拆分成预期通货膨胀率和Ex-ante实际利率两部分。为了解决SVAR模型识别条件不足的问题,本文使用BQ方法,认为实际利率冲击对名义利率没有长期影响,名义利率的长期波动全部来源于预期通货膨胀率的波动。随后,使用Band-Pass滤波方法得到实际利率的主趋势,通过累加SVAR模型中短期冲击得到Ex-ante实际利率的随机波动,主趋势和随机波动相加得到Ex-ante实际利率,进而得到预期通货膨胀率序列。本文最后分析了货币政策的倾向。 展开更多

我们使用三状态Markov区制转移模型研究了从1999年10月至2010年11月中国实际利率的时间序列行为。结果显示,Ex-post实际利率在不同时期具有显著不同的均值、方差,而本质上仍是一种随机游走。我们构建了Ex-ante实际利率序列。我们亦证明... 我们使用三状态Markov区制转移模型研究了从1999年10月至2010年11月中国实际利率的时间序列行为。结果显示,Ex-post实际利率在不同时期具有显著不同的均值、方差,而本质上仍是一种随机游走。我们构建了Ex-ante实际利率序列。我们亦证明,在合理长度阶段的平稳Ex-ante实际利率符合一些金融理论和金融模型,如"费雪效应"、"Black-Scholes期权定价公式"等。最后我们基于历史事实和研究结果强调,Ex-ante实际利率的潜在动态特征对于政策制定具有重要意义。 展开更多

CO_(2) utilization becomes a promising solution for reducing anthropogenic greenhouse gas (GHG) emissions. Biomass-based CO_(2) utilization (BCU) even has the potential to generate negative emissions, but the corresponding quantitative evaluation is limited. Herein, the biomass-based CO_(2) utilization with an iron cycle (BCU-Fe) system, which converts CO_(2) into formate by Fe under hydrothermal conditions and recovers Fe with biomass-derived glycerin, was investigated. The GHG reduction potential under various process designs was quantified by a multidisciplinary method, including experiments, simulations, and an ex-ante life-cycle assessment. The results reveal that the BCU-Fe system could bring considerable GHG emission reduction. Significantly, the lowest value is −34.03 kg CO_(2)-eq/kg absorbed CO_(2) (−2.44 kg CO_(2)-eq/kg circulated Fe) with the optimal yield of formate (66%) and Fe (80%). The proposed ex-ante evaluation approach not only reveals the benefits of mitigating climate change by applying the BCU-Fe system, but also serves as a generic tool to guide the industrialization of emerging carbon-neutral technologies. 展开更多
