Ifβ= Y=θ, a change in capital will not affect the ratio of wages between skill types. Thus,
wages across skill will be affected similarly by a change in the corporate tax rate.
Ifβ> Y>θ, a change in capital increases the ratio of wages between L1 and L2 and the ratio
of wages between L2 and L3. If L1 is high-skill labor, L2 is middle-skill labor and L3 is low-
skill labor and the capital-skill complementarity hypothesis holds, a change in capital should
have the largest effect on high-skill labor. Thus, a change in the corporate tax rate is
predicted to have the largest impact on the wages of high-skill workers.
