Like in previous studies, which assumed that productive capital is either fixed or absent, optimal macroprudential policy disincentivizes borrowing ex ante and supports borrowing when fire sales emerge. Yet, in an economy with endogenous capital formation, macroprudential policy harms capital formation and reduces the stock of collateral, such that the optimal policy in non-crisis times intervenes less than under fixed or no capital. Different to an economy without capital formation, this policy yields modest results in terms of crisis prevention and welfare gains. The combination of macroprudential policy with investment policy eliminates most crises and leads to substantially higher welfare gains, outperforming pure macroprudential policy. Under this policy mix borrowing is disincentivized more strongly and investment is supported ex ante. 2026-01-01T00:00:00Z The effect of information framing on policy support: Experimental evidence from urban policies Arlinghaus, Johanna Brigitte Konc, Théo Mattauch, Linus Sommer, Stephan https://hdl.handle.net/10419/302449 2024-10-01T08:51:24Z 2024-01-01T00:00:00Z Title: The effect of information framing on policy support: Experimental evidence from urban policies Authors: Arlinghaus, Johanna Brigitte; Konc, Théo; Mattauch, Linus; Sommer, Stephan 2024-01-01T00:00:00Z Does Household Heterogeneity across Countries Matter for Optimal Monetary Policy within a Monetary Union?
