We study the effects of model uncertainty in a simple New-Keynesian model using robust control techniques. Due to the simple model structure, we are able to find closed-form solutions for the robust control problem, analysing both instrument rules and targeting rules under different timing...

This thesis consists of an introductory chapter and three essays, all of which aim to study the functioning of a small open economy. The thesis starts with an investigation of export and import price determination and moves to a small open economy DSGE model framework in order to study the role...

This paper studies financial market disturbances as sources of investment fluctuations in Finland during 1995–2008. We construct a DSGE model of the Finnish economy that incorporates two domestic financial market shocks and financial frictions in the form of a BGG financial accelerator. We...

This paper presents a two-sector, two-country model showing that inflation in the housing market, a low personal savings rate, and a construction investment boom can contribute to a large current account deficit. In the model, demand by a group of households in the domestic country is...

This thesis consists of four essays in empirical macroeconomics. The first three essays examine the conduct of monetary policy during a disinflationary and deflationary era, with the policy interest rates close to or at the zero bound. The questions of interest include the potency of the...

In this essay we study the optimal non-coordinated fiscal policy in a monetary union, where a common and independent monetary authority commits to optimally set the union-wide nominal interest rate. The national governments in the monetary union implement independent fiscal policies by choosing...

This paper investigates price setting of internationally traded goods. We develop a theoretical model that incorporates sticky prices in the currency of both the buyer (local currency pricing) and seller (producer currency pricing). The nature of price setting is thus forward looking and the...

In this paper we build a dynamic stochastic general equilibrium model of a small open monetary union with optimal monetary and fiscal policy, to study the transmission of country specific shocks and associated exchange rate fluctuations. We show that movements of the monetary union’s exchange...

Countercyclical country interest rates have been shown to be both a distinctive characteristic and an important driving force of business cycles in emerging market economies. In order to account for this, most business cycle models of emerging market economies have relied on ad hoc and exogenous...
