This paper develops a dynamic general equilibrium model in innite ho- rizon, with an endogenous banking sector, market sensitive regulatory con- straints, and in which deterministic rational housing bubbles may emerge. We are interested in the conditions under which housing bubbles may emerge and their impact on the economy. We show that 1) when agents face a LTV regulation, two dierent equilibria may emerge and coexist: a bubbleless and a housing bubble equilibria; 2) housing bubbles increase banks' size; 3) when banks face operational costs, housing bubbles reduce welfare. In an extension of the model we introduce a stochastic banking bubble and show that the combination of two market sensitive macroprudential regu- lations, LTV and VaR regulations, allows housing and banking bubbles to arise simultaneously. Their interaction amplies banks' balance sheet size. The welfare impact is positive.
