Random Input-output Model Based on Normal Distribution
Jichun Wang · Journal of Huaihai Institute of Technology · 2008
In real economic systems,it is not realistic to describe the regular but changing socio-economic phenomena with certainty variables because of the complexity,variability and randomness of socio-economic activities.Therefore,it is of practical significance to study random input-output model by using random-variable-sum theory.Taking direct consumption coefficient and final demand as the precondition of normal random variables,this paper probes into the random input-output model and derives the equations that satisfy the total output of all departments.
