This function computes the CES demand coefficient matrix.
1 |
sigma |
a numeric m-vector or m-by-1 matrix. |
alpha |
a nonnegative numeric m-vector or m-by-1 matrix. |
Beta |
a nonnegative numeric n-by-m matrix. |
p |
a nonnegative numeric n-vector or n-by-1 matrix. |
Theta |
null or a positive numeric n-by-m matrix. |
A demand coefficient n-by-m matrix is computed which indicates the demands of agents (firms or consumers) for obtaining unit product or utility with CES production functions or utility functions (e.g. alpha*(beta1*x1^sigma+beta2*x2^sigma)^(1/sigma) or alpha*(beta1*(x1/theta1)^sigma+beta2*(x2/theta2)^sigma)^(1/sigma)) under the price vector p.
