Beiträge zur Jahrestagung des Vereins für Socialpolitik 2012: Neue Wege und Herausforderungen für den Arbeitsmarkt des 21. Jahrhunderts - Session: Credit Markets D05-V1
We study an exchange economy with overlapping generations of consumers who derive utility from consuming a non-durable commodity and housing. A banking sector offers loans to finance housing. We provide a complete characterization of the equilibrium dynamics which alternates between an expansive regime where housing prices increase and banks expand loans and a contractive regime associated with decreasing housing values and shrinking credit volume. Regime switches occur even under small but persistent income changes giving rise to large booms and busts in housing prices not reflecting changes in fundamentals.
