We greatly expand the space of tractable term-structure models. We consider one example that combines positive yields with rich volatility and correlation dynamics. Bond prices are expressed in closed form and estimation is straightforward. We find that the early stages of a recession have...

The paper explores the macroeconomic consequences of fiscal consolidations whose timing and composition - either tax- or spending-based - are uncertain. We find that the composition of the fiscal consolidation, its duration, the monetary policy stance, the level of government debt, and...

In this report, the authors examine and compare twelve private and public sector models of the Canadian economy with respect to their paradigm, structure, and dynamic properties. These open-economy models can be grouped into two economic paradigms. The first is the "conventional" paradigm (or...

This paper studies the implications of certain kinds of uncertainty for monetary policy. It first describes the optimum policy rule in a simple model of the transmission mechanism as in Ball and Svensson. It then examines how this rule ought to be modified when there is uncertainty about the...

In this report, we evaluate several simple monetary policy rules in twelve private and public sector models of the Canadian economy. Our results indicate that none of the simple policy rules we examined is robust to model uncertainty, in that no single rule performs well in all models. In fact,...

How can policy-makers avoid large policy errors when they are uncertain about the true model of the economy? The author discusses some recent approaches that can be used for that purpose under two alternative scenarios: (i) the policy-maker has one reference model for choosing policy but cannot...

Surveys provide direct information on expectations, but only short histories are available at quarterly frequencies or for long-horizon expectations. Longer histories typically contain only semi-annual observations of short-horizon forecasts. The authors fill in the gaps by constructing a...

Suppose that the dynamics of the macroeconomy were given by (partly) random fluctuations between two equilibria: "good" and "bad." One would interpret currency crises (or recessions) as a shift from the good equilibrium to the bad. In this paper, the authors specify a dynamic...

The author explores the role that Taylor-type rules can play in monetary policy, given the degree of uncertainty in the economy. The optimal rule is derived from a simple infinite-horizon model of the monetary transmission mechanism, with only additive uncertainty. The author then examines how...
