Credit constraints that link a private agent’s debt to market-determined prices embody a credit externality that drives a wedge between competitive and constrained socially optimal equilibria, inducing private agents to overborrow. The externality arises because agents fail to internalize the...

On February 12, 2010, SUERF, the Oesterreichische Nationalbank and the Bankwissenschaftliche Gesellschaft continued their established tradition of jointly organised conferences. As evidenced also by the 115 conference participants, this year's subject of "Contagion and Spillovers – New...

This paper establishes that one can generally obtain a purely quadratic approximation to the unconditional expectation of social welfare when the steady-state is distorted. A specific example is provided employing a canonical New Keynesian model. Unlike in the non-distorted steady state case,...

We develop a simple and intuitive approach for analytically deriving unconditionally optimal (UO) policies, a topic of enduring interest in optimal monetary policy analysis. The approach can be employed to both general linear-quadratic problems and to the underlying non-linear environments. We...

On 4 March 2011, SUERF – The European Money and Finance Forum and the National Bank of Poland jointly organised a conference on the theme of: "Monetary Policy after the Crisis". Following a call for papers with a large number of submissions, the scientific committee selected 9 papers, which...

This paper studies the efficiency of financial intermediation through securitization with asymmetric information about the quality of securitized loans. In this theoretical model, I show that, in general, by providing reputation-based implicit recourse, the issuer of a loan can credibly signal...

This paper studies how macroprudential policy tools can complement the interest rate-based monetary policy in achieving a selection of dual stabilization objectives. We show analytically in a canonical New Keynesian model with collateral constraints that using the loan-to-value ratio as an...

To analyse the interdependence between monetary and fiscal policy during a financial crisis, we develop an open-economy DSGE model with monetary and fiscal policy as well as financial markets in a continuous-time framework based on stochastic differential equations. Monetary policy is modelled...
