I analyse the dynamics of a New Keynesian DSGE model where the financing of investments is affected by a moral hazard problem. I solve for jointly Ramsey-optimal monetary and macroprudential policies. I find that when a financial friction is present in addition to the standard nominal friction,...

​According to EU legislation, the national authorities should use the principle of 'guided discretion' in setting the countercyclical capital buffer (CCB), which increases banks' resilience against systemic risk associated with periods of excessive credit growth. This means that the decision...

​I propose a financial stress index (FSI) for the Finnish financial system that aims to reflect the functionality of the financial system and provide an aggregate measure of financial stress in the money, bond, equity and foreign exchange markets and the banking sector. The FSI is a composite...

This paper analyses the evolution of the safety and soundness of the European banking sector during the various stages of the Basel process of capital regulation. In the first part we document the evolution of various measures of systemic risk as the Basel process unfolds. Most strikingly, we...

The global financial crisis has led to increased attention on the relationship of household indebtedness and systemic risks. As a result, macroprudential measures aimed at reducing the risks have been introduced in many countries. This note reviews the recent empirical literature on these...

This theoretical paper explores the effects of costly and non-costly collateral on moral hazard, when collateral value may fluctuate. Given that all collateral is costly, stochastic collateral will entail the same positive incentive effects as nonstochastic collateral, provided the variation in...

We show how banks' excessive risk-taking, stemming from informational asymmetries in loan markets, can lead to an excessive output loss when a recession starts. Risk-based capital requirements can alleviate the output loss by reducing excessive risk-taking in ‘normal' times. Model simulations...

This paper demonstrates that subordinated debt (‘subdebt' thereafter) regulation can be an effective mechanism for disciplining banks. Under our proposal, investors buy the subdebt of a bank only if they receive favourable information about the bank, and the bank is subject to a regulatory...

We study the effects on credit allocation and bank stability of introducing a leverage ratio requirement (LRR) on top of risk-based capital requirements, as in Basel III. For the current 3% LRR, both low-risk and high-risk loan rates and volumes remain essentially unchanged, because banks...

The financial liberalization in the four Nordic countries (Denmark, Finland, Norway, and Sweden) that took place mostly in the 1980s led to a major financial crisis in three of those countries. The crises in Finland, Norway, and Sweden are among the deepest financial crises in advanced market...
