Abstract Background Reduction of post-harvest loses crops are crucial tasks in ensuring food and nutrition security. However, a lack knowledge on the extent losses its associated impeding factors posing major challenges to effectiveness grain loss management strategy scale up for all other crop types Ethiopia. The study estimates magnitude identifies determinants. Methodology A national-level a...

This study assessed the determinants of intensity of improved rice varieties adoption using the Tobit model and also employed. The Heckman Two-stage model was used to identify the determinants of market participation and its potential impact on farming households’ welfare in three states selected from the three notable rice producing ecologies in Nigeria. A crosssectional data of 600 rice farme...

The standard approaches to estimating minimum variance hedge ratios (MVHRs) are mis-specified when futures prices are subject to price limits. This paper proposes a bivariate tobit-FIGARCH model with maturity effects to estimate dynamic MVHRs using single and multiple period approaches. Simulations and an application to a commodity futures hedge support the proposed approach and highlight the i...

Biological quantitative data are subjected to censoring when a portion of values cannot be quantified because they are smaller or greater than the limit of detection (LOD) of the laboratory assay. In genetic association studies of quantitative trait, the handling of censored data has received little attention and often the solutions are unsatisfactory. However, the approach used to deal with su...

In this study, we analyze the environmental efficiency performance and its determinants of 29 manufacturing industries in China from 2006 to 2011 by employing a two-stage DEA (data envelopment analysis)-Tobit model. For providing comparative and robust evidence, the 29 manufacturing industries are classified into three groups based on the pollution intensity. In the first stage, a SBM (slacks-b...
