This paper analyzes the efficiency of risk-taking decisions in an economy that is prone to systemic risk, captured by financial amplification effects that occur in response to strong adverse shocks. It shows that decentralized agents who have unconstrained access to a complete set of Arrow...

The investment fund sector, the largest component of the non-bank financial system, is growing rapidly and the economy is becoming more reliant on investment fund financial intermediation. This paper builds a dynamic stochastic general equilibrium model with banks and investment funds. Banks...

I study economies where banks do not fully internalize the social costs of default, which distorts their lending decisions. In all these economies, a common general equilibrium effect leads to aggregate over-investment. As a result, under laissez-faire, crises are too frequent and too costly...

This paper studies how mortgage borrowers and house prices react to a tightening of mortgage limits following a policy change in Ireland in 2015. The policy introduced limits to the loan-to-income and loan-to-value ratios of new mortgages issued. In response to a tightening borrowing constraint,...

We use a dynamic general equilibrium model featuring a banking sector to assess the interaction between macroprudential policy and monetary policy. We find that in “normal” times (when the economic cycle is driven by supply shocks) macroprudential policy generates only modest benefits for...

Since its creation the euro area suffered from imbalances between its core and peripheral members. This paper checks whether macroprudential policy tools - applied in a countercyclical fashion as known from the DSGE literature to the peripheral countries - could contribute to providing more...

I analyze the impact of raising capital requirements on the quantity, composition, and riskiness of aggregate investment in a model in which firms borrow from both bank and non-bank lenders. The bank funds loans with insured deposits and costly equity, monitors borrowers, and must maintain a...

We study the identification of policy shocks in Bayesian proxy VARs for the case that the instrument consists of sparse qualitative observations indicating the signs of certain shocks. We propose two identification schemes, i.e. linear discriminant analysis and a non-parametric sign concordance...

We analyse the interaction between monetary and macroprudential policies in the euro area by means of a two-country DSGE model with financial frictions and cross-border spillover effects. We calibrate the model for the four largest euro area countries (i.e. Germany, France, Italy, and Spain),...

Since the onset of the Global Financial Crisis, the presence of institutional investors in housing markets has steadily increased over time. Real estate funds (REIFs) and other housing investment firms leverage large-scale buy-to-rent investments in real estate assets that enable them to set...
