   Sammanfattning : Sweden experienced a remarkable economic transformation between the 18th century and the outbreak of World War I. This dissertation consists of four self-contained papers that uses a quantitative empirical approach to identify key drivers of this transformation by analyzing the contribution of the potato to economic growth, the determinants of the early investments in mass schooling, and how the rollout of the national railroad network shaped rural and urban growth patterns from the mid-19th century to the present day.

   Sammanfattning : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. LÄS MER
