On the systemic nature of weather risk [PDF]
Agricultural Finance Review, 2010 PurposeThe purpose of this paper is to assess the losses of weather‐related insurance at different regional levels. The possibility of spatial diversification of insurance is explored by estimating the joint occurrence on unfavorable weather conditions in different locations, looking particularly at the tail behavior of the loss distribution.Design ...
