This thesis concerns the transmission of monetary policy shocks on the unemployment rate in Norway over the past 20 years. The study compares impulse response functions from local projections - estimated through OLS and IV regressions - and SVAR methodologies - identified with short-term restrictions and external instruments. While touching upon the identification problem, this study contributes to existing literature by providing a comparison framework for how identification strategies affect model results. I note a delayed response of the unemployment rate to normalized policy shocks through both methodologies. Peak impact is observed after a period of 10 quarters, while quantitatively the response is of a small size. The response is similar for a local projection specified as in Jordà (2005) and for a two-variable SVAR model specified as in Sims (1980). The use of external instruments amplifies the response in local projections, but causes a loss of statistical significance in the SVAR responses. I extend the model to consider dependencies of the impact of monetary policy changes on the current level of interest rates or unemployment rates. As a measure of robustness, I provide estimates for polynomial local projections, and a five-variable SVAR model that includes GDP, the implicit price deflator, and exchange rates - allowing for various lag selections and variable ordering.
