Plain-text version

If Y=L^αK^β is a Cobb-Douglas production function with two factors labor and capital, then the presence of constant returns to scale exhibited by the production function can be tested using. (A) only t statistic (B) only F statistic (C) both t and F statistic (D) χ² statistic

Also written as: If Y=L^(alpha)K^(beta) is a Cobb-Douglas production function with two factors labor and capital, then the presence of constant returns to scale exhibited by the production function can be tested using.
