CASE STUDY

Sometimes formulation of plans and policies requires the knowledge of future trends. For examples, an economic planner has to decide in 2019 how much the economy should produce in 2020. In other words, one must know what could be the expected level of consumption in 2020 in order to decide the production plan of the economy for 2020. In this situation one might make subjective judgment based on the guess about consumption in 2020. Alternatively, one might use statistical tools to predict consumption of past years or of recent years obtained by surveys. Thus statistical methods help to formulate appropriate economic policies that solve economic problems.
