A factor of production i is called znferior if the conditional demand for that factor decreases as output increases; that is, ax, (w, y)/dy
(a) Draw a diagram indicating that inferior factors are possible.
(b) Show that if the technology is constant returns to scale, then no factors can be inferior.
(c) Show that if marginal cost decreases as the price of some factor increases, then that factor must be inferior.
A three-phase, 60-Hz substation bus supplies two wye-connected loads that are connected in parallel through a three-phase feeder that has a per phase impedance of 0.5 + j2 Ω. Load 1 draws 50 kW at 0.866 lagging PF, and load 2 draws 36 kVA at 0.9 l..
Carry out a sensitivity analysis on the adipic acid project described in Example 9.5. Investigate the sensitivity of the 10-year NPV to variation in total fixed capital (-20% to +50%), annual gross profit (-20% to +30%), and project construction s..
Derive an equation for the latent heat of fusion that is a function of the radius of the particle. Using this equation, for a copper particle that has a radius of 2.5 nm, find the ratio of the latent heat of fusion of the particle to the laten..
