Purpose – The purpose of this research is examine the development of livestock mortality insurance, and associated challenges, in order to provide an improved understanding regarding the operation of livestock mortality insurance. Design/methodology/approach – In a many countries, livestock...

Purpose – The purpose of this paper is to explain the factors affecting crop insurance purchases by farmers in Inner Mongolia, China. Design/methodology/approach – A survey of farmers in Inner Mongolia, China, is undertaken. Selected variables are used to explain crop insurance purchases,...

Purpose – China frequently suffers from weather-related natural disasters and weather risk is recognized as a source of wide-spread systemic risk throughout large swaths of China. During these periods farmers' crops are at risk and for a largely poor population few can afford the turmoil to...

We present an approach for exact maximum likelihood estimation of parameters from univariate and multivariate autoregressive fractionally integrated moving average models with Gaussian errors using the Expectation Maximization (EM) algorithm. The method takes advantage of the relation between...

We present an approach via a multivariate preconditioned conjugate gradient (MPCG) algorithm for maximum likelihood estimation of parameters from vector ARFIMA models with Gaussian errors. This approach involves the solution of a block-Toeplitz system, and Monte Carlo integration over the...
