  1. 1. Expectations, Uncertainty, and Monetary Policy

    Detta är en avhandling från Uppsala : Nationalekonomiska institutionen

    Författare :David Kjellberg; Uppsala universitet.; [2007]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Monetary Policy; Expectations; Uncertainty; Uncovered Interest Parity; Interest Rates; SOCIAL SCIENCES Business and economics Economics; SAMHÄLLSVETENSKAP Ekonomi Nationalekonomi;

    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. 2. On Frequency Control Schemes in Power Systems with Large Amounts of Wind Power

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Camille Hamon; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Stochastic optimal power flows; Frequency control schemes; Tertiary frequency control; uncertainty; power systems;

    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.

  3. 3. Modelling the terrestrial carbon cycle – drivers, benchmarks, and model-data fusion

    Detta är en avhandling från Lund University, Faculty of Science, Department of Physical Geography and Ecosystem Science

    Författare :Zhendong Wu; Lunds universitet.; Lund University.; [2018-09]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Global carbon cycle; Ecosystem modeling; Uncertainty; LPJ-GUESS; Traceability Framework; Model-data fusion; Climate data;

    Sammanfattning : Det terrestra ekosystemet absorberar cirka en tredjedel av de antropogena utsläppen varje år, vilket är en avgörande ekosystemtjänst som minskar ökningstakten av atmosfärisk koldioxid och bidrar till att mildra klimatförändringen. Observerade koncentrationer av atmosfäriskt koldioxid uppvisar en stor årlig variabilitet som främst anses vara orsakad av det terrestra ekosystemets respons på klimatförändringar och antropogen aktivitet.

  4. 4. Modeling, Model Validation and Uncertainty Identification for Power System Analysis

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Tetiana Bogodorova; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system modelling; model validation; parameter identification; uncertainty identification; Modelica; Electrical Engineering; Elektro- och systemteknik;

    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. 5. Macroeconomic Uncertainty and Exchange Rate Policy

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Post; Uppsala universitet.; [2007]
    Nyckelord :Social sciences; SAMHÄLLSVETENSKAP;

    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
