SERIES EXPANSION OF THE SABR JOINT DENSITY

Under the SABR stochastic volatility model, pricing and hedging contracts that are sensitive to forward smile risk (e.g., forward starting options, barrier options) require the joint transition density. In this paper, we address this problem by providing closed‐form representations, asymptotically, of the joint transition density. Specifically, we construct an expansion of the joint density through a hierarchy of parabolic equations after applying total volatility‐of‐volatility scaling and a near‐Gaussian coordinate transformation. We then establish an existence result to characterize the truncation error and provide explicit joint density formulas for the first three orders. Our approach inherits the same spirit of a small total volatility‐of‐volatility assumption as in the original SABR analysis. Our results for the joint transition density serve as a basis for managing forward smile risk. Through numerical experiments, we illustrate the accuracy of our expansion in terms of joint density, marginal density, probability mass, and implied volatilities for European call options.     

Der Patient als Partner

Die Patientenedukation schlie?t eine umfassende Information und Beratung des Betroffenen hinsichtlich der verschiedenen Aspekte seiner Erkrankung ein. Gerade bei geriatrischen Patienten mit oft komplexen Krankheitsbildern ist sie oft die Voraussetzung für ein weiteres selbstst?ndiges Leben. Was geh?rt alles dazu?

我国家庭信贷状况研究：基于CHFS微观数据的分析

文章利用中国家庭金融调查2013年发布的调查数据,分别构建非参数次序probit模型和Heckman模型检验了影响城乡家庭信贷约束状况和贷款可得性的相关因素。结果表明,户主受教育程度和家庭收入水平提高、家庭资产规模增加等都能缓解家庭的信贷约束,户主的党员身份、大学以上的受教育程度以及家庭资产规模等能提高家庭的贷款可得性,户主年龄、风险偏好等变量对家庭信贷规模的边际效应显著为负,而尽管城市家庭和东部地区家庭获得的贷款支持更多,但是城市家庭和东部地区家庭还是面临着更大信贷约束。     

县域节水潜力分析

以苏北泗洪县为例,在分析现状节水的基础上,进一步明确下一阶段的节水重点,并测算规划年节水水平下现状用水的节水潜力。分析结果表明:按照2020年、2030年的节水水平,泗洪县现状年节水潜力分别达6 365.1万m3和12 623.5万m3,节水潜力较大,未来泗洪县应当以节水优先为前提来统筹安排县域水资源管理的各项工作。

The role of behavioural factors and opportunity costs in farmers' participation in voluntary agri-environmental schemes: A systematic review

Agri-environmental schemes (AESs) are increasingly implemented to promote the adoption of environmentally friendly practices by farmers. We use a systematic review to explore the role of behavioural factors and opportunity costs in farmers' decisions to participate in AESs in Australia, Europe and North America. Behavioural factors influence how farmers value and perceive options, while opportunity costs relate to farmers' forgone utility when choosing to participate in schemes. We synthesise insights from 79 articles and over 700 factors explaining the participation in AESs. We find that a set of behavioural factors seem consistently connected to participation, including agricultural training, advice and having positive attitudes towards AESs. Moreover, several factors related to opportunity costs also have a rather consistent relationship with AES participation, including market conditions, implementation efforts, profitability, and management and contract flexibility. However, many relationships of behavioural factors and opportunity costs with AES participation are not as consistent and generalizable as sometimes portrayed and require context-specific interpretation. Those factors with mixed results can still provide insights into farmers' participation decisions as several of them are either ‘positively and insignificantly’ or ‘negatively and insignificantly’ related to participation, such as environmental attitude, trust and farm size. These results suggest that their relationship with AES participation depends on other factors or the setting, highlighting interactions and raising important new research questions. Overall, our results provide several entry points for both researchers and policy-makers, highlighting uncertainties in relationships between factors and participation that should be considered when designing policies.
