We look for a theoretical justification of nominal wage contracts in household diversification of risk. We assume it is more costly for households than for firms to use financial markets for this purpose. In a calibrated general equilibrium model we find from stochastic simulation that where...

Calvo contracts, which are the basis of the current generation of New Keynesian models, widely include indexation to general inflation. We argue that the indexing formula should be expected inflation rather than lagged inflation. This optimises the welfare of the representative agent in a...

This paper establishes the ability of a Real Business Cycle model to account for real exchange rate (RXR) behaviour, using UK experience as empirical focus. We show that a productivity burst simulation is capable of explaining the appreciation of RXR and its cyclical pattern observed in the...

This paper develops a political economy model of multiple unemployment equilibria to provide a theory of an endogenous natural rate of unemployment. This model is applied to the UK and the US interwar period which is remembered as the decade of mass unemployment. The theory here sees the natural...

We use the method of indirect inference to test a full open economy model of the UK that has been in forecasting use for three decades. The test establishes, using a Wald statistic, whether the parameters of a time-series representation estimated on the actual data lie within some confidence...

The paper uses a general equilibrium model of regional labor markets, in which national and local factors interact to determine local wages and unemployment; when mobility between regions is obstructed by rent subsidies and controls, unemployment and wage differentials arise. Because...

This paper investigates optimal indexation in the New Keynesian model, when the indexation choice includes the possibility of partial indexation and of varying weights on rational and lagged indexation. It finds that the Calvo contract adjusted for rationally expected indexation under both...

We use the method of indirect inference, using the bootstrap, to test the Smets and Wouters model of the EU against a VAR auxiliary equation describing their data; the test is based on the Wald statistic. We find that their model generates excessive variance compared with the data. But their...

We develop a theoretical nonlinear model of equilibrium unemployment and test its policy implications for a number of OECD countries. The theory here sees the natural rate and the associated equilibrium path of unemployment as endogenous, pushed by the interaction of shocks (mainly...

It is argued that trigger mechanisms cannot support reputation if voters are atomistic and have access to good information about party preferences. Therefore the choice for a party lies between precommitment, enforced by penalties, and discretion. The paper uses a model of Labor and Conservative...
