Instability of agricultural production

Instability of agricultural production reflects, among other things, the vulnerability of countries to natural shocks, in particular impacts of droughts and disturbances in rainfall patterns. The index of instability follows the same calculation principles as for the export instability index. The logarithm of agricultural production is regressed, on a trend T and the delayed endogenous variable. The standard deviation of the estimate is used as a measure of agricultural instability. Performance score from 0 to 100. The lowest score reflects the best situation.
