Pari-mutuel wagering functions as a very simple financial market, and has therefore been important in studying market efficiency. In this study, an SPRT-like test reveals that probabilities from the win pool corrected for the favourite longshot bias using Asch and Quandt's regression equation...

Purpose – The purpose of this paper is to explain the factors affecting farmers’ willingness to purchase weather index insurance for crops in China, in the Province of Hainan, and to also provide additional background information on weather index insurance. Design/methodology/approach – A...

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 While crop insurance ratemaking has been studied for many decades, it is still faced with many challenges. Crop insurance premium rates (PRs) are traditionally determined only by point estimation, and this approach may lead to uncertainty because it is sensitive to the underwriter’s...

Purpose: The purpose of this paper is to propose a new margin protection (MP) scheme for the producers of hog, cattle and dairy in the developing countries. Design/methodology/approach: The proposed MP scheme is inspired by the Livestock Gross Margin (LGM) program that has been successfully...

The main objectives of this paper are to construct a new risk model for modelling the Hybrid-Takaful (Islamic Insurance) and to develop a computational procedure for calculating the associated ruin probability. Ruin probability is an important study in actuarial science to measure the level of...

In this paper, we study two classes of optimal reinsurance models by minimizing the total risk exposure of an insurer under the criteria of value at risk (VaR) and conditional value at risk (CVaR). We assume that the reinsurance premium is calculated according to the expected value principle....

In this paper, we study two classes of optimal reinsurance models from the perspective of an insurer by minimizing its total risk exposure under the criteria of value at risk (VaR) and conditional value at risk (CVaR), assuming that the reinsurance premium principles satisfy three basic axioms:...

In this paper, we consider the problem of optimal partial hedging for a contingent claim subject to a preset hedging budget constraint. Under some technical assumptions on the hedged loss function and the market pricing functional, the optimal partial hedging strategy, which minimizes the...

In this paper, we propose to combine the Marginal Indemnification Function (MIF) formulation and the Lagrangian dual method to solve optimal reinsurance model with distortion risk measure and distortion reinsurance premium principle. The MIF method exploits the absolute continuity of admissible...
