Economists have tried to determine the factors that affect economic growth process. Neoclassical growth models state that the policy maker has not opportunity to design policies that improve economic growth. But modern theories state the opposite. In that sense, fiscal policy, innovation processes, human capital improvement..., are some elements that improve growth. In that way, the housing sector would play a relevant play in the economic growth process, direct and indirectly. The main goal of this paper is to study this role of the housing sector taking into account the Spanish case.
