1. Expectations, Uncertainty, and Monetary Policy
Sammanfattning : Essay 1 - To evaluate measures of expectations I examine and compare some of the most common methods for capturing expectations: the futures method which utilizes financial market prices, the VAR forecast method, and the survey method. I study average expectations on the Federal funds rate target, and the main findings can be summarized as follows: i) the survey measure and the futures measure are highly correlated; the correlation coefficient is 0.

2. On Frequency Control Schemes in Power Systems with Large Amounts of Wind Power
Sammanfattning : In recent years, large investments have been made in wind power, and this trend is expected to continue in the coming decades. Integrating more wind power in the production mix offers great opportunities for the society, such as reducing greenhouse gas emissions and the dependence on foreign fuel. LÄS MER
3. Modelling the terrestrial carbon cycle – drivers, benchmarks, and model-data fusion
Sammanfattning : The terrestrial ecosystem sequesters about one-third of anthropogenic emissions each year, thereby providing a critical ecosystem service that slows the rate of increase of atmospheric carbon dioxide and helps mitigate climate change. Observed atmospheric carbon dioxide concentrations exhibit a large inter-annual variability which is considered to be caused primarily by the response of the terrestrial ecosystem to climate change and anthropogenic activity.

4. Modeling, Model Validation and Uncertainty Identification for Power System Analysis
Sammanfattning : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.

5. Macroeconomic Uncertainty and Exchange Rate Policy
Sammanfattning : Essay 1 (with Annika Alexius) uses a structural VAR model to study the role of floating exchange rates for five "small open economies" with inflation targets. We show that only in Sweden and Canada does the nominal exchange rate behave in a stabilizing way. Most exchange rate movements are responses to non-fundamental shocks. LÄS MER
