Mainstream macro-models have assumed away financial frictions, in particular default. The minimum addition in order to introduce financial intermediaries, money and liquidity into such models is the possibility of default. This, in turn, requires that institutions and price formation mechanisms...

What is the main limitation of much modern macro-economic theory, among the failings pointed out by William R. White at the 2010 Mayekawa Lecture? We argue that the main deficiency is a failure to incorporate the possibility of default, including that of banks, into the core of the analysis....

The purpose of this paper is to assess the choice between adopting a monetary base or an interest rate setting instrument to maintain financial stability. Our results suggest that the interest rate instrument is preferable, since during times of a panic or financial crisis the Central Bank...

Until recently, financial services regulation remained largely segmented along national lines. The integration of financial markets, however, calls for a systematic and coherent approach to regulation. This paper studies the effect of market based regulation on the proper functioning of the...

We show, in a monetary exchange economy, that asset prices in a complete markets general equilibrium are a function of the supply of liquidity by the Central Bank, through its effect on default and interest rates. Two agents trade goods and nominal assets to smooth consumption across periods and...

We develop a multi-period general equilibrium model of bank deposit, credit, and interim inter-bank loan markets in which banks initially specialize in their choices of debtors, leading to under-diversification, but nevertheless become entwined via inter-bank markets, leading to the fortunes of...

The paper proposes a measure of financial fragility that is based on economic welfare in a general equilibrium model calibrated against UK data. The model comprises a household sector, three active heterogeneous banks, a central bank/regulator, incomplete markets, and endogenous default. We...

he article defines the framework to assess the financial stability as currently practised by central banks and international organizations. The author criticizes the comparison of the current methodology to the practices of central banks three or four decades ago. The article provides a brief...

This paper sets out a tractable model which illuminates problems relating to individual bank behaviour, to possible contagious inter-relationships between banks, and to the appropriate design of prudential requirements and incentives to limit ‘excessive’ risk-taking. Our model is rich enough...
