In the framework of a panel survey, observational units of a given cohort may undergo significant changes from one year to another, due to endogenous or exogenous events. Those changes, including disappearance (attrition), division or merger, negatively affect the quality of panels because they directly influence the sample size and the weight of the observational units. In this work, we explore applications of the weight sharing methods developed in the literature to address these issues in panel surveys with a special focus on agricultural surveys. The paper covers issues with changes in both agricultural households and agricultural land.
