    Sammanfattning : Controlled-source electromagnetic methods are imaging techniques applied at/on the surface of the Earth which record the electromagnetic field in order to assess the electrical conductivity distribution of the Earth’s subsurface, along with anomalies in this material property, as well as to characterise and interpret structures in Earth’s crust. Extracting information from the recorded electromagnetic data requires inverse modelling algorithms. LÄS MER

  3. 2. Essays on externalities, regulation, institutions, and firm performance

    Sammanfattning : This thesis is devoted to the empirical analysis of how externalities—the nonexistence of private markets in some good or the absence of sufficient incentives to establish such markets— affect firm performance and growth. A minor part investigates a direct link between positive externalities, in the form of localized knowledge spillovers, and firm growth, by testing the so-called local export spillover hypothesis: Exporting firms in a region may reduce export entry costs for other local firms through export-related informal knowledge and information flows.
