The global Great Recession has sparked renewed interest in the relationships between financial conditions and real activity. This paper considers the Swiss experience, studying the impact of credit market conditions and housing prices on real activity over the last three decades through the lens of a medium-scale structural Bayesian vector autoregressive model. From a methodological point of view, the analysis is challenging for two reasons. First, we must cope with a large number of variables which leads to a high-dimensional parameter space in our model. Second, the identification of economically interpretable shocks is complicated by the interaction among many different relevant factors. As to the first challenge, we use Bayesian shrinkage techniques to make the estimation of a large number of parameters tractable. Specifically, we combine a Minnesota prior with information from training observations to form an informative prior for our parameter space. The second challenge, the identification of shocks, is overcome by combining zero and sign restrictions to narrow the plausible range of responses of observed variables to the shocks. Our empirical analysis indicates that while credit demand and, in particular, credit supply shocks explain a large fraction of housing price and credit fluctuation, they have a limited impact on real activity.

This paper examines the macroeconomic consequences of selecting alternative exchange rate regimes of countries in three regions. In particular, it studies whether Austria, the Netherlands, Canada and New Zealand made the right monetary regime choices between 1970 and 2000. We focus on the role of asymmetric shocks as a core determinant for the evaluation of various monetary regimes by studying the impact of a hard peg, a full monetary union, or floating exchange rates (with or without inflation targeting) on selected macroeconomic variables. Estimates of structural VARs are used to ascertain if the countries under review meet the essential ingredients of an Optimum Currency Area (OCA) and thus are candidates for a monetary union. Counterfactual experiments help to study economic outcomes had these countries pursued alternative monetary strategies. We conclude that a floating regime with inflation targeting is best for Canada, a monetary union with Australia is the best course of action for New Zealand, and monetary union is the appropriate choice for the Netherlands while there are reasons to believe that Austria might have been better off with a floating regime, at least for a time. We also find that good monetary policy is not confined to any particular exchange rate regime and that political and institutional factors weigh heavily in this decision.
