  1. 1. Interactions between carbon and power markets in transition

    Författare :Jörn Constantin Richstein; Mehrdad Ghandhari Alavijh; Margot P.C. Weijnen; Laurens J. de Vries; Remco Verzijlbergh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EU ETS; carbon market; investment; electricity; agent-based modelling; EMLab-Generation; price floor; price ceiling; price corridor; market stabil- ity reserve; MSR; Energy Technology; Energiteknik; Economics; Nationalekonomi;

    Sammanfattning : In this research, several improvements to the European Union Emissions Trading System (EU ETS) were analysed. The EU ETS is a market for emission allowances and the European Union's main instrument for reducing greenhouse gas emissions (of which CO2 is the main component). LÄS MER

  3. 2. Predicting who stays or leaves after the acquisition: : Target’s top manager turnover

    Författare :Keivan Aghasi; Terrence Brown; Massimo Colombo; Maureen McKelvey; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Acquisition; CEO turnover; TMT turnover; coordination; Founder-CEO; Similarity attraction; Diversity;

    Sammanfattning : In acquisition of high-tech and knowledge intensive firms, scholars have paid special attention to top managers’ status after the deal. Literature suggests that these managers in particular CEOs if kept in post-acquisition provide coordination capacity for the acquirer to transfer the knowledge and technology from the target to the acquirer while minimizing the disruptive effect of post-acquisition integration process.

    Sammanfattning : The production and consumption of information and communication technology (ICT) products and services continue to grow worldwide. This trend is accompanied by a corresponding increase in electricity use by ICT, as well as direct environmental impacts of the technology. Yet a more complicated picture of ICT’s effects is emerging. LÄS MER

    Sammanfattning : The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals.
