Recent literature on the design of optimal monetary policy has shown that deviations fromprice stability are small whenever prices are sticky. This paper reconsiders this issue byintroducing capital accumulation in the model. Optimal monetary policy in this setupimplies small deviations from...

Die Frage nach der Kausalität fällt in die Methodologie. Methodologie ist in denWirtschaftswissenschaften ein Bereich, der sowohl bei Ökonomen als auch bei Philosophenkaum Beachtung findet. ....

We extend the Carlstrom and Fuerst (American Economic Review,1997, 87, pp. 893–910) agency cost model of business cycles by includingtime-varying uncertainty in the technology shocks that affectcapital production. We first demonstrate that standard linearizationmethods can be used to solve the...

In this paper we investigate the stock market response to international monetary policychanges in the UK and Germany. Specifically, we analyse the impact of (un)expectedchanges in UK and German/Euro area policy rates on UK and German aggregate andsectoral equity returns in an event study. The...

The paper evaluates the performance of three popular monetary policy rules when the central bank is learning aboutthe parameter values of a simple New Keynesian model. The three policies are: (1) the optimal non-inertial rule; (2)the optimal history-dependent rule; (3) the optimal price-level...

A striking fact about pricing is the prevalence of \sales": large temporary price cuts followedby prices returning exactly to their former levels. This paper builds a macroeconomic modelwith a rationale for sales based on firms facing customers with different price sensitivities.Even if firms...

In a country with high probability of default, higher interest rates may render the currency lessattractive if sovereign default is costly. This paper develops that intuition in a simple model andestimates the effect of changes in interest rates on the exchange rate in Brazil using data from...

This paper computes welfare-maximizing monetary and tax policy feedback rules in acalibrated dynamic general equilibrium model with sticky prices. The government makesexogenous final good purchases, levies a proportional income tax, and issues nominalone-period bonds. A quadratic approximation...

Structural models for pricing risky debt imply a negative relationship betweeninterest rates and credit spreads. In contrast, credit default swap pricing modelsassume independence between credit risk and the term structure of interest rates.So far, empirical studies have focused on first...

This paper examines the question to what extent premia for macroeconomic risks inbanking are sufficient to avoid banking crises. We investigate a competitive bankingsystem embedded in an overlapping-generations model subject to repeatedmacroeconomic shocks. We show that even if banks fully...
