Suppose That Utility Over Consumption and Leisure Takes the Constant $u ( \ell , c ) = \left( \alpha \ell ^ { - \rho } + ( 1 - \alpha ) c ^ { - \rho } \right) ^ { - 1 / \rho }$

True/False

Suppose that utility over consumption and leisure takes the constant elasticity of substitution form $u ( \ell , c ) = \left( \alpha \ell ^ { - \rho } + ( 1 - \alpha ) c ^ { - \rho } \right) ^ { - 1 / \rho }$ .If $\rho$ falls between 0 and -1,then the labor supply curve is backward bending.
