This paper incorporates Nash bargaining, credible bargaining and efficiency wages as special cases of an over-arching model of wage determination in a matching model that is used to assess econometrically how well each fits US data.  With Nash bargaining, estimates for worker bargaining power...

This paper examines under what conditions fiscal policy in the form of government spending should contribute to macroeconomic stabilisation.  To this end optimal fiscal targeting rules minimising the microfounded social loss are examined in the following settings.  Firstly, for the benchmark...

We consider optimal monetary and fiscal policies in a New Keynesian model of a small open economy with sticky prices and wages.  In this benchmark setting monetary policy is all we need - analytical results demonstrate that variations in government spending should play no role in the...

This 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...

I address the issue of the `number` of International Monetary Equilibria that the international finance model of Geanokoplos 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...

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...

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...
