    Abstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

  3. 2. Public goods games for collective agri-environmental contracts design

    University essay from SLU/Dept. of Economics

    Author : Riccardo Spada; [2024]
    Keywords : Framed field experiment; Cooperation; Collective action; Heterogeneous endowment;

    Abstract : This thesis conducts a structured literature review of public goods games (PGG) experiments to analyze the differences between laboratory and field studies and to understand whether farmers cooperate more or less than standard PGG subjects. In addition, novel data on public goods games conducted on European farmers from Germany, Hungary, Netherlands, and Poland are analyzed to understand the effect of heterogeneous starting endowments on cooperation.
