Can Crop Insurance Premiums be Reliably Estimated?
Ramirez, Octavio A.; Carpio, Carlos E.; Rejesus, Roderick M. - Agricultural and Applied Economics Association - AAEA - 2009
The objective of this paper is to compare the accuracy of crop insurance rating methods based on historical liability and indemnity data (similar to the procedure currently used by the Risk Management Agency) and “yield distribution” approaches. Estimated rates are compared to “true”...

Modelling yield risk measures of major crop plants
Kobus, Pawel - European Association of Agricultural Economists - EAAE - 2012
The paper deals with the problem of modelling yield risk measures for major crop plants in Poland. Hence, in some cases the gamma distribution offers a better fit to the data than normal distribution, and in addition to linear models, generalized linear models were also used. The research was...

Estimating Farm Level Multivariate Yield Distribution Using Nonparametric Methods
Zheng, Qiujie; Wang, H. Holly; Shi, Qinghua - Agricultural and Applied Economics Association - AAEA - 2008
Modeling crop yield distributions has been an important topic in agricultural production and risk analysis, and nonparametric methods have gained attention for their flexibility in describing the shapes of yield density functions. In this article, we apply a nonparametric method to model joint...

The Effect of the El Nino Southern Oscillation on U.S. Corn Production and Downside Risk
Tack, Jesse B.; Ubilava, David - Southern Agricultural Economics Association - SAEA - 2012
El Nino Southern Oscillation (ENSO) teleconnections imply anomalous weather conditions around the globe, causing yield shortages, price changes, and even civil unrests. Extreme ENSO events may cause catastrophic damages to crop yields, thus amplifying downside risk for producers. This study...

ON ADAPTATION TO CLIMATE CHANGE AND RISK EXPOSURE IN THE NILE BASIN OF ETHIOPIA
Di Falco, Salvatore; Veronesi, Marcella - European Association of Agricultural Economists - EAAE - 2011
This study investigates the impact of climate change adaptation on farm households’ downside risk exposure (e.g., risk of crop failure) in the Nile Basin of Ethiopia. The analysis relies on a moment-based specification of the stochastic production function. We estimate a simultaneous equations...
