I construct an estimable statistic that predicts whether a financial innovation will spread. The approach embeds the multi-host SIR model from epidemiology within a financial model of correlated securities trade; and takes advantage of the related predictive tools from mathematical epidemiology,...

We reconsider the role of an inflation conservative central banker in a setting with distortionary taxation. To do so, we assume monetary and fiscal policy are decided by independent authorities that do not abide to past commitments. If the two authorities make policy decisions simultaneously,...

In this paper we discuss a number of challenges for structural macroeconomic models in the light of the Great Recession and its aftermath. It shows that a benchmark DSGE model that shares many features with models currently used by central banks and large international institutions has...

Monetary policy is often analysed in terms of simple rules. Such rules may be useful for many purposes, even when they do not describe the actual monetary policy strategy exactly. This paper compares monetary policy in Sweden during the inflation-targeting regime 19932002 with the policies...

Using a small empirical model of inflation, output, and money estimated on U.S. data, we compare the relative performance of monetary targeting and inflation targeting. The results show that monetary targeting would be quite inefficient, with both higher inflation and output variability. This is...

We use high-frequency administrative data from Germany to study the effects of monetary policy on income and employment across the earnings distribution. Earnings growth at the bottom of the distribution is substantially more elastic to policy shocks. This unequal incidence is driven by...

This paper assesses to what extent forecasters make efficient use of competitors' forecasts. Using a panel of forecasters, I find that forecasters underuse information from their competitors in their forecasts for current and next year's annual GDP growth and in ation. The results also show that...

This paper presents estimates of the effects of monetary policy shocks on the Swedish economy. A theoretical model of an open economy is used to identify a structural VAR model. The empirical results from the identified VAR model are compared with two less structural approaches for...

In this paper, we evaluate the consequences of super-active fiscal policy rules - that is, rules that call for tax cuts and/or spending increases as the government's debt level rises - in a standard New Keynesian model subject to an occasionally-binding zero lower bound on the monetary policy...

I study the welfare performance of a policy regime of fiscal activism in which fiscal policy acts as an automatic stabilizer and controls inflation, while monetary policy pegs the nominal interest rate. When evaluated through the lens of a standard New Keynesian model, accounting for price and...
