In this paper we analyse the effect of model uncertainty on the wealth and utility outcomes of an investment decision. We compute optimal portfolio weights for domestic and foreign assets and using these weights we construct end investment horizon wealth and utility ratios. Model uncertainty is...

Monetary policy conducted in real time has to take into account the preliminary nature of recent national accounts data. Not only recent data, but also figures dating many years back are potentially subject to revisions. This means that there is a danger that an important part of the central...

We formulate and estimate a RBC model with structural changes and with bounded rationality, where the economic agents have to learn about the former. This paper investigates whether the agents’ learning process can generate business cycles fluctuations which are empirically plausible....

Grandmont (1985) found that the parameter space of even the simplest, most classical models are stratified into bifurcation regions. Barnett and He (1999,2002) subsequently found transcritical, codimension-two, and Hopf bifurcation boundaries within the parameter space of the policy-relevant...

We derive a framework (and provide a software toolkit) which allows the dynamic general equilibrium modeller to specify what variables are in households' information sets, and the degree to which these variables are measured with error. We apply this framework to a canonical real business cycle...

In this paper I introduce human capital accumulation with time-to-build technology into a real business cycle model. The only driving force is an exogenous shock affecting the long-run equilibrium level of productivity. A positive shock is assumed to generate a rise in the long-run equilibrium...
