  1. 1. Essays on Unemployment and Real Exchange Rates

    Författare :Hans Lindblad; Torsten Persson; Ragnar Nymoen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Exchange Rates; Labor Mobility; NAIRU; Natural Rate; Phillips Curve; Economics; Nationalekonomi; Economics; nationalekonomi;

    Sammanfattning : In the first essay, Persistence in Swedish Unemployment Rates, we study if there is no or weak tendency in unemployment rates to revert back to previous levels. Persistence is caused by: natural rate shocks, long unemployment cycles, and spill-over from cyclical to permanent unemployment. We find evidence of high persistence. LÄS MER

  3. 2. Studies in Saving under Uncertainty

    Författare :Eva Skult; Mats Persson; Paul Klein; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Precautionary Saving; Mutual Altruism; Samaritan s Dilemma; Uncertain Lifetime; Economics; Nationalekonomi; Economics; nationalekonomi;

    Sammanfattning : This thesis consists of three essays.In Precautionary Saving under Correlated Risk, I show that the sign of the correlation between the random variables might determine whether saving increases or decreases when risk is introduced. Precautionary saving is thus not confirmed. LÄS MER

  4. 3. Hyperoxia avoidance and aggregation behavior in C. elegans

    Författare :Annelie Persson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; c. elegans; aggregation;

    Sammanfattning : Living in the soil, C. elegans can move in three dimensions in search for food. To navigate, it partly uses oxygen levels as a description of its habitat. Oxygen tension may indicate presence of microbial food and location with respect to the surface, where oxygen is 21%. LÄS MER

  7. 5. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications

    Författare :Kristin Persson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extinction theorem; inverse source problem; integral representation; radome diagnosis; near-field transformation;

    Sammanfattning : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. LÄS MER
