This paper reviews recent advances in the specification and estimation of Bayesian Vector Autoregressive models (BVARs). After describing the Bayesian principle of estimation, we first present the methodology originally developed by Litterman (1986) and Doan et al. (1984) and review alternative...

Conventional wisdom teaches that the output response upon a fiscal expansion is higher under fixed than floating exchange rates for a small open economy. We analyse the effects of fiscal expansions using a New Keynesian model and find that this result reverses in times of sovereign default risk....

In standard macroeconomic models, debt sustainability and price level determinacy are achieved when fiscal policy avoids explosive debt and monetary policy controls inflation, irrespective of the relative strengths of each policy stance. We examine how these policy requirements for equilibrium...

At least since the euro area sovereign debt crisis, it is evident that country risk premium shocks have adverse economic effects, not only in emerging economies, but advanced economies as well. Using a Bayesian Panel Vector Autoregression model, we find that increases in the risk premium lower...

We study the stabilization properties and welfare implications of a fiscal capacity in a New Keynesian model for a monetary union. A novel feature of the model is that access to the fiscal capacity is conditional on a country’s public debt accumulation being sufficiently low. Likewise, the...
