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 purpose of our work is to explore contagious financial crises. To this end, we use simplified, thus numerically solvable, versions of our general model [Goodhart, Sunirand and Tsomocos (2003)]. The model incorporates heterogeneous agents, banks and endogenous default, thus allowing various...

This paper extends the model proposed by Goodhart, Sunirand, and Tsomocos (2003,2004a, b) to an infinite horizon setting. Thus, we are able to assess how the model conforms with the time series data of the U.K. banking system. We conclude that, since the model performs satisfactorily, it can be...

The objective of this paper is to propose a model to assess risk for banks. Its main innovation is to incorporate endogenous interaction between banks, recognising that the actual risk to which an individual bank is exposed also depends on its interaction with other banks and other private...

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 to...

We propose a metric of financial stability that is a weighted average of the probability of default and the equity of each country. The weights are obtained in the VAR and must reflect that the welfare changes due to financial instability are produced primarily through changes of the probability...

We show, in an exchange economy with default, liquidity constraints and no aggregate uncertainty, that state prices in a complete markets general equilibrium are a function of the supply of liquidity by the Central Bank. Our model is derived along the lines of Dubey and Geanakoplos (1992). Two...

Many institutional changes have taken place to payments systems. Indeed, they have been in continual change ever since money first emerged as the dominant technology for conducting transactions. Means of settlement between banks have changed: cheques replaced cash in many transactions, and they...

We define a non-tâtonnement dynamics in continuous-time for pure exchange economies with outside and inside fiat money. Traders are myopic, face a cash-in-advance constraint, and play dominant strategies in a short-run monetary strategic market game involving the limit-price mechanism. The...
