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...

Not only in the classic Arrow-Debreu model, but also in many mainstream macro models, an implicit assumption is that all agents honour their obligations, and thus there is no possibility of default. That leads to well-known problems in providing an essential role for either money or for...

We show that, in a monetary equilibrium, trade and asset prices depend on both the supply of the liquidity by the Central Bank and the liquidity of assets and commodities. As a result, monetary aggregates are informative for the conduct of monetary policy. We also show asset prices are higher in...

We define continuous-time dynamics for exchange economies with fiat money. Traders have locally rational expectations, face a cash-in-advance constraint, and continuously adjust their short-run dominant strategy in a monetary strategic market game involving a double-auction with limit-price...

This paper introduces agent heterogeneity, liquidity, and endogenous default to a DSGE framework. Our model allows for a comprehensive assessment of regulatory and monetary policy, as well as welfare analysis in the different sectors of the economy. Due to liquidity and endogenous default, the...

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...
