    Author : Love Rönnelid; Iain Cameron; Steffen Hindelang; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Investment law; enforcement; foreign direct investment FDI ; power; investment insurance; bilateral investment treaties BITs ; World Trade Organisation WTO ; Multilateral Investment Guarantee Agency MIGA ; International Centre for Settlement of Investment Disputes ICSID ; development; developmental state; regulatory space; development strategies; law and development; New York Convention; Aron Broches; Ibrahim Shihata; Wilhelm Röpke; Friedrich Hayek; rule of law; good governance; Public International Law; Folkrätt;

    Abstract : This dissertation explores how the enforcement of international investment law became so powerful. It does so by tracing the different legal developments that have enabled the strength of the present regime. In this respect, the two aims of providing investment protection and that of fostering economic development are examined. READ MORE

  5. 18. Quantitative vulnerability analysis of electric power networks

    Author : Åke J. Holmgren; Torbjörn Thedéen; Lars-Göran Mattsson; Terje Aven; KTH; []
