We review heterogeneous agent-based models of financial stability and their application in stress tests. In contrast to the mainstream approach, which relies heavily on the rational expectations assumption and focuses on situations where it is possible to compute an equilibrium, this approach...

This paper analyzes the design of simple macroprudential rules for bank and non-bank credit markets in a medium-scale dynamic stochastic general equilibrium model. In the model, mutual funds support corporate bond issuance by firms with access to capital markets; a banking sector supplies loans...

This paper shows that the effect of inflation on asset prices and real aggregates depends on the financial intermediation sector. When firms finance using nominal long-term debt issued by financial intermediaries, unexpected changes in inflation lead to a wealth transfer across sectors. Higher...

The global financial crisis shattered the conventional wisdom about how financial markets work and how to regulate them. Authorities intervened to stop the panic-short-term pragmatism that spoke volumes about the robustness of mainstream economics. However, their very success in taming the...

Loan loss provisions in the euro area are negatively related to GDP growth, i.e., they are procyclical. Loan loss provisions tend to be more procyclical at larger and better capitalized banks. The procyclicality of loan loss provisions can explain about two-thirds of the variation of bank...

This paper studies optimal bank capital requirements in a model of endogenous bank funding conditions. I find that requirements should be higher during good times such that a macroprudential "buffer" is provided. However, whether banks can use buffers to maintain lending during a financial...

The recent rise of nonperforming loans (NPLs) in some Asian economies calls for close analysis of the determinants, the potential macrofinancial feedback effects, and the implications for financial stability in the region. Using a dynamic panel model, we assess the determinants of the evolution...

How does news about future economic fundamentals affect within-country and cross-country credit allocation? How effective is unconventional policy when financial crises are driven by unfulfilled favorable news? I study these questions by employing a two-sector, two-country macroeconomic model...

We examine the system-wide effects of liquidity regulation on banks’ balance sheets. In the general equilibrium model, banks have to hold liquid assets, and choose among illiquid assets varying in the extent to which they are difficult to value before maturity, e.g., structured securities. By...

We propose a simple model that captures the link between bank and sovereign credit risk. It allows evaluating policy options to address this 'doom loop' in which the government may need to raise debt to recapitalise banks, and an increase in government debt raises sovereign risk and in turn...
