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 introduction of Basel II has raised concerns about the potential impact of risk-sensitive capital requirements on the business cycle. Several approaches have been proposed to assess the procyclicality issue. In this paper, we adopt a general equilibrium model and conduct comprehensive...

This paper proposes a measure of financial fragility that is based on economic welfare in a general equilbrium 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...

I address the issue of the 'number' of International Monetary Equilibria that the international finance model of Geanakoplos and Tsomocos (2002) possesses. The mainstream competitive model has locally unique equilibria with respect to the real side of the economy; however, it manifests nominal...

We analyze a market game where traders are heterogeneous with respect to their rationality level and have asymmetric information. The market mechanism results into a statistical equilibrium, where traders randomise among their available actions due to their limited rationality. We provide a...

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...

As financial stability has gained focus in economic policymaking, the demand for analyses of financial stability and the consequences of economic policy has increased. Alternative macroeconomic models are available for policy analyses, and this paper evaluates the usefulness of some models from...

We show in an exchange economy with liquidity constraints that the volume of trade and asset prices depend on both the supply of liquidity by the Central Bank and on the liquidity of assets and commodities. As a result, monetary aggregates are informative for the assessment of economic...

This paper first extends the canonical General Equilibrium with Incomplete Markets (GEI) model with money and default to allow for competitive banking and financial instability. Second, it introduces capital requirements for the banking sector to assess the short and medium term macroeconomic...

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...
