Dynamic Life Cycle Model: Frisch Elasticity<br />

Frisch intertemporal labor supply elasticity defined as:<br />

δ = ( w t<br />

l t<br />

) ∂l<br />

∂w t<br />

| λ<br />

Experiment: change wage rate in one period only, holding all other<br />

wages, and consumption profile constant<br />

Can show that δ > 0: work more today to take advantage of<br />

temporarily higher wage<br />

In separable case:<br />

l t = v ′−1 (λw t /[β(1 + r)] t )<br />

⇒<br />

∂l<br />

λ<br />

| λ =<br />

∂w t β(1 + r) t v ′′ (l t ) > 0<br />
