   Sammanfattning : This dissertation consists of four self-contained essays.Essay IThis essay reports on an experimental study of how voluntary contributions in a public good game are affected by framing. In the public good context, average wealth improves from contributions. In the defensive contexts, the voluntary contributions prevent reductions in average wealth. LÄS MER

3. 27. Energy Export Opportunities from Kraft Pulp and Paper Mills and Resulting Reductions in Global CO2 Emissions

   Sammanfattning : With increasing energy prices and increasing demand for CO2-lean energy sources, energy savings in the pulp and paper industry become ever more relevant. Significant energy savings in kraft mills can be made by e.g. improved heat integration and installation of an energy-efficient evaporation plant. LÄS MER

4. 28. Health trends of the ageing population in Sweden : association of mortality reductions with morbidity and quality of life improvements

   Författare :Korinna Karampampa; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Since the beginning of the 19th century, and particularly after the 1950s, life expectancy of the elderly in all developed countries, including Sweden, has increased substantially, posing the question whether the health of the ageing population has also been improving over time. The aim of this PhD thesis was to investigate morbidity occurrence among the elderly in Sweden, attempting to answer the question of whether their overall health and quality of life has been improving over time in parallel with mortality reductions.
