Existing DSGE models are not able to reproduce the observed influence of international business cycles on small open economies. We construct a two-sector New Keynesian model to address this puzzle. The set-up takes into account intermediate trade and producer heterogeneity, where goods and...

There are two main approaches to modelling monetary policy; simple instrument rules and optimal policy. We propose an alternative that combines the two by extending the loss function with a term penalizing deviations from a simple rule. We analyze the properties of the modified loss function by...

We analyze the influence of the Taylor rule on US monetary policy by estimating the policy preferences of the Fed within a DSGE framework. The policy preferences are represented by a standard loss function, extended with a term that represents the degree of reluctance to letting the interest...

This paper analyzes the effects of fiscal policy in an open economy. We extend the savers-spenders theory of Mankiw (2000) to a small open economy with endogenous labor supply. We first show how the Dornbusch (1983) consumption-based real interest rate for open economies is modified when labor...

We suggest that overconfidence among policymakers explains why formal decision power over monetary policy is given to committees, while much of the real power to set policy remains with central bank chairmen. Overconfidence implies that the chairman underweights advice from his staff, increasing...

What drives the recent inflation surge? To answer this question, one must decompose inflation fluctuations into the contribution of structural shocks. We document how whimsical such a historical shock decomposition can be in standard vector autoregressive (VAR) models. We show that the...

An apparent disconnect has taken place between inflation and economic activity in the US over the last 25 years, with price inflation remaining remarkably stable in spite of large fluctuations in the output gap and other measures of economic slack. This observation has led some to believe that...

How and to what extent are small open economies affected by international shocks? I develop and estimate a medium scale DSGE model that addresses both questions. The model incorporates i) international markets for firm-to-firm trade in production inputs, and ii) producer heterogeneity where...

The recent oil price fall has created concern among policy makers regarding the consequences of terms of trade shocks for resource-rich countries. This concern is not a minor one - the world's commodity exporters combined are responsible for 15-20% of global value added. We estimate a...

We estimate a structural vector autoregressive model in order to quantify four main explanations for the decline of the US labor income share: (i) rising market power of firms, (ii) falling market power of workers, (iii) higher investmentspecific technology growth, and (iv) the widespread...
