农户气象感知对购买天气指数保险意愿的影响——以山西岢岚和江苏南通430食用豆户为例

目的 综合已有研究发现,学者忽略了农户的气象认知对其天气指数保险购买意愿的影响。方法 文章基于山西省岢岚和江苏省南通市430食用豆种植户的实地问卷调查数据,运用Probit模型分析食用豆种植户对气象（如平均气温、平均降雨、干旱、霜冻等的发生次数及严重程度）的感知对其购买天气指数保险意愿的影响。结果 （1）食用豆种植户的气象感知显著地影响其购买天气指数保险的意愿。此外,食用豆种植户的村干部经历和兼业户身份对其购买天气指数保险产生正向且显著的影响;（2）而家庭人口数以及是否有专门的食用豆贮藏场所等对食用豆种植户购买天气指数保险产生负向且显著的影响。结论 因此,在食用豆种植户中推广天气指数保险应关注到其气候的感知,可以通过多种方式（例如公益宣传片、教育培训等,线上线下、网络电视手机、书籍宣传册等）宣传气候变化对食用豆种植的危害,强化食用豆种植户的风险管理意识,进而提高其购买天气指数保险的意愿。     

林农森林保险需求影响因素分析——以云南492户林农为例

调查了云南492户林农,采用二元Logistic模型分析了林农森林保险需求的主要影响因素,结果表明:林农林保态度、是否购买过其他保险、灾害发生强度和频率、林地质量、林地是否有保护树种和流转限定对林农森林保险需求有显著正向影响。因此,政策性森林保险应以病虫害险和火灾险为突破口,恰当选择森林保险试点;拓宽宣传渠道,强化林农风险意识;实行流转限定等措施;拓宽森林保险险种范围,创新投保形式。     

Farm households’ risk perception,attitude and adaptation strategies in dealing with climate change: Promise and perils from rural Pakistan

Pakistan is highly vulnerable to extreme climatic events, such as floods and droughts. This study determines the farmers’ risk perception, risk attitude, adaptation measures and various aspects of vulnerability to climate change (e.g. floods, droughts, heavy rainfalls, pests and disease) at farm level in rural Pakistan. The risk perception and attitude of farm households are crucial factors that influence farm productivity, investment and management decisions at this level. A well-designed questionnaire was used to interview 720 farm households from six districts of the Khyber Pakhtunkhwa province. A binary logit model was used to determine the main factors that affect the choice of adaptation strategies of the farm household. The findings revealed that crop diversification, changing crop varieties, altering the crop calendar, varying the fertilizer used, mulching and farm insurance were the main adaptation strategies followed by farm households. The results of the binary logit model revealed that age, education, farm size, household size, credit accessibility, annual income and the perception on the increase in temperature and decrease in rainfall had significant influence on the selection of the adaption strategies. The findings of this study can provide guidance, policy recommendations and reference for future researchers.

Farmers’ risk preferences and their climate change adaptation strategies in the Yongqiao District,China

Farmers’ risk preferences play an important role in agricultural production decisions. This study characterizes risk preferences among farmers in Yongqiao and determines how these risk preferences are related to their choices regarding climate change adaptation strategies. We find that most farmers in the study area were aware of climate change. They were taking measures to protect their livelihoods against perceived changes to the local climate. The risk experiment result shows that the representative subject was risk averse, and women were more risk averse than men. The relationships between farmers’ risk preferences and different climate change adaptation choices were different. Farmers’ risk aversion was negatively and significantly related with adaptation strategies on planting new crop varieties and adopting new technology, but it had a significantly positive effect on purchasing weather index crop insurance. The results also indicate that the level of education, farming experience, farm size, household income and perception of climate change impacts influence farmers’ adaptation decisions.     

基于农户视角的农业巨灾风险评估与测度

[目的]探索农业巨灾风险的有效评估与水平测量,既是"三农"风险管理的要求,也是加强农村防灾减灾能力建设的重要途径之一。[方法]文章以我国28个不同省份地区的651个村1 355户农户的入户调查数据和国家统计局统计数据作为样本,运用模糊层次分析法(FAHP)构建农业巨灾风险评估指标体系,对我国农业巨灾风险进行评估与测度。[结果]我国农业巨灾风险总体属于高风险等级,而区域风险分布差异较大,西部风险最高,中部居中,东部风险最小。其中,西部和中部区域的农业巨灾风险属于高风险,东部区域属于中等风险。东部区域在防灾减灾能力、承灾主体能力、孕灾环境水平、防灾减灾保障性等方面均优于中西部区域。[结论]研究认为,在影响农业巨灾风险的因素中,虽然客观致灾因子无法规避,但建设提高孕灾环境水平和防灾减灾能力,可降低农业巨灾的风险感知与风险程度;同时,培育风险文化和建设经济能降低风险脆弱性。     

Factors Affecting Farmers’ Crop Insurance Participation in China

China's latest crop insurance program, launched in 2007, provides an excellent opportunity to explore the factors affecting farmers’ crop insurance purchase decisions, particularly decision making when crop insurance was first introduced into rural communities. This study surveyed all households in Kuangjiaqiao Village, Changde, Hunan Province, China over a four‐year period, from 2007 to 2010. Using basic regression models for cross‐sectional analysis and advanced models to consider lag effects, this study identifies the dominant factors influencing farmers’ crop insurance decisions. Results indicate farmers developed a dynamic adaptive process toward the new crop insurance. Farmers initially made relatively arbitrary decisions that were significantly influenced by community insistence or pressure to conform. Then, farmers gradually established more rational decision‐making mechanisms in which yield volatility, education, and engagement experience became statistically significant. The focus on the initial stages of the crop insurance program from this study helps improve our understanding of the demands within this rapidly growing market in China.     

Coping with systemic risk in index‐based crop insurance

The implementation of index‐based crop insurance is often impeded by the existence of systemic risk of insured losses. We assess the effectiveness of two strategies for coping with systemic risk: regional diversification and securitization with catastrophe (CAT) bonds. The analysis is conducted in an equilibrium pricing framework which allows the optimal price of the insurance and the number of traded contracts to be determined. We also explore the role of basis risk and risk aversion of market agents. The model is applied to a hypothetical area yield insurance for rice producers in northeast China. If yields in two regions are positively correlated, we find that enlarging the insured area leads to higher insurance premiums. Unless capital market investors are very risk averse, a CAT bond written on an area yield index outperforms regional diversification in terms of certainty equivalents of both farmers and insurers.     

Farmers' Preferences for Crop Insurance Attributes

Utilizing survey data from corn and soybean farmers in the Midwest, this study assesses the relative importance of different features of crop insurance products. Conjoint analysis results indicate that farmers' preferences for flexibility dominate both type of insurance and coverage level. Revenue insurance demand is greater by those who are larger, younger, and farm in more separate locations. Results are significant and consistent by size, insurance usage, leverage, and risk perception. The results permit prediction of market shares of competing insurance products within specific producer segments, and thus also provide guidance for targeting specific producer groups with new product configurations.     

风险感知、风险态度对农村土地经营权流转的影响研究 ——以浙江省嘉兴市农村土地经营权流转为例

研究目的:探究风险感知、风险态度对农村土地经营权流转的影响作用,为推进农村土地流转制度创新实践提供理论和实证依据。研究方法:将风险感知理论与风险态度理论相结合,探讨两者对农村土地经营权流转的影响作用,提出研究假设,并通过浙江省嘉兴市农户的调查数据进行验证。研究结果:(1)风险感知对农村土地经营权流转产生显著负向影响;(2)风险态度对农村土地经营权流转产生显著负向影响;(3)风险感知和风险态度的交互作用对农村土地经营权流转产生显著负向影响,表明具有较小风险规避程度的农户,即使感知到农村土地经营权流转具有较大风险时,流转土地经营权的可能性也将增加。研究结论:农村土地制度创新实践中,关注风险感知因素和风险态度因素将有助于推进农村土地经营权流转。     

Adoption of weather‐index insurance: learning from willingness to pay among a panel of households in rural Ethiopia

In this article we examine which farmers would be early entrants into weather‐index insurance markets in Ethiopia, were such markets to develop on a large scale. We do this by examining the determinants of willingness to pay for weather insurance among 1,400 Ethiopian households that have been tracked for 15 years as part of the Ethiopian Rural household Survey. This provides both historical and current information with which to assess the determinants of demand. We find that educated, wealthier individuals are more likely to purchase insurance. Risk aversion is associated with low insurance take‐up suggesting that models of technology adoption can inform the purchase and spread of weather index insurance. We also assess how willingness to pay varied as two key characteristics of the contract were varied and found that basis risk reduces demand for insurance particularly when the price of the contract is high, and that provision of insurance through groups is preferred by female headed households and individuals with lower levels of education.     

Managing basis risk with multiscale index insurance

Agricultural index insurance indemnifies a farmer against losses based on an index that is correlated with, but not identical to, her or his individual outcomes. In practice, the level of correlation may be modest, exposing insured farmers to residual, basis risk. In this article, we study the impact of basis risk on the demand for index insurance under risk and compound risk aversion. We simulate the impact of basis risk on the demand for index insurance by Malian cotton farmers using data from field experiments that reveal the distributions of risk and compound risk aversion. The analysis shows that compound risk aversion depresses demand for a conventional index insurance contract some 13 percentage points below what would be predicted based on risk aversion alone. We then analyze an innovative multiscale index insurance contract that reduces basis risk relative to conventional, single‐scale index insurance contract. Simulations indicate that demand for this multiscale contract would be some 40% higher than the demand for an equivalently priced conventional contract in the population of Malian cotton farmers. Finally, we report and discuss the actual uptake of a multiscale contract introduced in Mali.     

农业绿色发展模式的农业保险需求引致效应——基于荔枝种植户的经验分析

目的 研究农业绿色发展模式引致的农业风险规避需求及其特点,提出完善和推广农业保险、推进农业绿色发展的政策启示。方法 文章将农户农业保险需求分为5个等级,以采用生物防控和非化学生长调节技术来衡量农业绿色发展模式,然后构建排序Logit模型,利用2018—2019年国家荔枝龙眼产业技术体系的调查数据证明农业绿色发展模式和农业保险需求之间引致效应,并借助OLS、2SLS、LIML和分位数回归法检验了模型的稳健性。结果 （1）排序模型中农业绿色发展模式的系数均在1%的显著性水平上显著,说明农户的农业绿色发展模式会引致显著的农业保险需求,年龄、种植经验、合作组织、种植规模的系数也显著不为0,体现出种植规模较大、种植时间较长、参加合作组织的非老年人农户对农业保险需求影响较明显;（2）0.50分位数回归的农业绿色发展模式系数值最大,表明农业绿色发展模式引致的农业保险需求往往处于中等水平。结论 政府政策应充分考虑和满足农户农业绿色发展模式中的风险规避需求,才能深入推进农业绿色发展;而促进农业绿色发展的农业保险费率标准与推广策略也需要充分考虑农户种植规模、种植经验、合作组织、农户年龄和中等水平的农业保险需求等因素。     

Hedging dairy production losses using weather-based index insurance

This article proposes a temperature–humidity index insurance product and examines whether this product can effectively protect against the risk of reduced milk production caused by heat stress. Results suggest that even when premiums are at higher than actuarially fair levels and the insurance purchaser is faced with both spatial and temporal basis risks, a temperature–humidity index insurance product would provide risk management benefits to a representative south‐central Georgia dairy producer.     

Optimal Insurance Against Climatic Experience

An optimal insurance contract against a climatic risk is derived in the presence of an uninsurable and dependent aggregate production risk. The optimal design depends on the stochastic dependency between both sources of uncertainty and on the producer's attitude towards risk, especially on his prudent behavior. Rational weather insurance purchasing decisions are also derived. The prudent producer responds to actuarially fair weather insurance by increasing his exposure towards risk.     

ECONOMIC ISSUES FROM THE BROADS GRAZING MARSHES CONSERVATION SCHEME

The paper examines two key issues relating to the use of fixed-price conservational contracts of the type embodied in the new Environmentally Sensitive Area policy in the UK. It uses data for the Broads Grazing Marshes Conservation Scheme (BGMCS). The budgetary costs of the fixed-price contract are compared to those of (i) public purchase of land with leaseback for grazing, and (ii) of individual management agreements. Using a net present value criterion, public purchase emerges as the cheapest option, and management agreements as a superior option in defined circumstances. The paper also explores equity and efficiency issues arising from fixed price contracts. It is concluded that for many farmers and landlords in the BGMCS the fixed payment exceeded what was necessary to achieve the conservational objectives, while at the same time it was less than the profit foregone by farmers who might possibly have switched to arable farming.

Risk Preferences of Dairy and Hog Producer in Quebec

The objective of this study is to investigate the nature of risk preferences of Quebec dairy and hog producers. The direct elicitation of utility method is employed to determine producers'degree of risk aversion. The Delphi process is used to obtain more refined and realistic responses. The results reveal that the risk preferences of the randomly selected Quebec farmers are highly diverse. The percentage of risk-taking farmers ranges from 8% to 23% depending upon the level of investment and the nature of the enterprise. On average, the majority of farmers in both groups are found to be risk averse. Based on the differences between the means as well as distributions, although not significant in all cases, hog producers are found to be consistently more risk averse than dairy producers. Moreover, the gap between the two groups widens as the level of investment increases. The implications of this result are that the stability of farm income due to supply management in dairy sector may facilitate investments of a given risk (for example, adoption of a new technology) more so than it would in the hog sector.     

Productivity,credit, risk,and the demand for weather index insurance in smallholder agriculture in Ethiopia

The article explores the relationship between fertilizer use and the demand for weather index insurance (WII) among smallholder farmers in Ethiopia. We examine whether fertilizer use is profitable under current smallholder production conditions, whether risk‐related factors affect fertilizer use, and we estimate the returns to inputs in the agricultural production function in the absence of insurance. We then study how these primitives of agricultural production functions relate to insurance demand. The study compares a survey‐based estimate of willingness to pay with actual uptake for the weather insurance, finding the stated and actual demand to be almost completely uncorrelated. While those with high marginal returns to inputs say they would purchase insurance, only those with low marginal returns actually do, consistent with the stated purpose of the product as input insurance. Insurance demand proves to be highly responsive to the existence and amount of randomly allocated insurance vouchers.
