Increasing international investment, the proliferation of international investment agreements, domestic legislation and investor-state contracts have contributed to the development of a new field of international law that defines obligations between host states and foreign investors with investor-state dispute settlements. This involves not only vast sums, but also a panoply of rights, duties and shifting objectives at the juncture of national and international law and policy. This engaging Research Handbook provides an authoritative account of these diverse investment law issues.Written by international experts in the field, the contributions provide economic, political and legal perspectives to cover all aspects of international and national investment law. With regional perspectives from Africa, Asia, Australia and New Zealand, Europe, and Latin and North America, this Research Handbook offers an analytical overview of the key areas of current research interest and developments in investment law. Vitally, the expert contributors outline future and upcoming issues, as well as providing a research agenda for the topic.This Research Handbook will be an excellent resource for researchers in academic institutions, governments and non-governmental organisations, as well as for practitioners including government officials, negotiators and practicing lawyers.Contributors: I.
