Proposition 5 Using (1), (3) and (20), the steady-state employment rate e(θ) =

Proof. Equation (20) can be written as
E = O ^ M = vE
and using (1) and (3), then
M* = VE
Mi — Me = vE
M _ M
p(θ)L = (v + p(θ)) Ê.
Therefore, e(θ) := = = follows. ■

Proof. Using equations (18), (19) in efficiency units, then
x = (1 + cis') y + cυv.
