4. 3. Two Essays in Empirical Finance: Unit-Root Testing in the Presence of Structural Breaks

   Författare :Florin G. Maican; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Essay 1: Real Exchange Rate Adjustment in European Transition Countries Essay 1 presents unit-root test results for real exchange rates in ten Central and Eastern European transition countries relative to the Euro during 1993:01-2005:12. Because of the shift from controlled to market economies and the accompanying crises, failed policy regimes and changes in exchange rate regimes, appropriate tests in transition countries require allowing for both structural changes and outliers.

5. 4. Essays on the term structure of interest rates and monetary policy

   Författare :Magnus Dahlquist; Stockholms universitet; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Penningpolitik; Ränta;

   Sammanfattning : This thesis consists of four empirical essays, summarized below.In “On Alternative Interest Rate Processes'' the interest rate dynamics for four European countries are studied. There seems to be a positive relation between the interest rate level and the volatility of interest rate changes. LÄS MER
