A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and I concentrate on the numerics and...

The paper deals with the application of Minimum Weighted Residual Methods (MWR) in intertemporal optimizing models of endogenous economic growth. In the 1st part of the paper the basics of the MWR method are described. Attention is mainly concentrated on one special class of MWR methods: the...

This paper investigates the effect of sovereign risk on the stochastic rational expectations equilibrium of a real business cycle small open economy. The credit market is imperfect because the sovereign cannot commit to repay its outstanding debt and chooses to default when it is optimal to do...

By simplifying the computational tasks and by providing step-by-step explanations of the procedures required to study a linear dynamic rational expectations (LDRE) model, this paper and the accompanying ``LDRE Toolbox' of Matalb functions guide a researcher with almost no experience in...

This paper extends the standard Real Business Cycle model to incorporate sectoral shifts in unemployment. Using relative sectoral technology and sectoral tastes shocks, combined with labor adjustment costs across sectors, we assess the possibility of generating persistent aggregate unemployment....

Theoretical study identifying one modality with conditions necesary for the financial stabilization of an inherently unstable system; and 5040 other unstable dynamic modes. It draws on knowledge made available by the academic field of Control Engineering.

We estimate output growth rate spectra for 58 countries. The spectra exhibit diverse shapes. To study the sources of this diversity, we estimate the short-run, business cycle, and long-run frequency components of the sampled series. For most OECD countries the bulk of the spectral mass is in the...

This paper asks two questions. First, can we detect empirically whether the shocks recovered from the estimates of a structural VAR are fundamental? Second, can the problem of non-fundamentalness be solved by considering additional information? The answer to the firrst question is 'yes' and that...

This paper studies the co-movements of unemployment and labor productivity growth for the U.S. economy. Measures of co-movements in the frequency domain indicate that co-movements between variables differ strongly according to the frequency. First, long-term and business cycle co-movements are...

This paper investigates the asymmetric effects of monetary shocks when the=20 impact of monetary policy on real activity works through state-dependent=20 variables. We use a nonlinear model, the multiple regime smooth transition=20 autoregressive model, that allows the effects of shocks to vary...
