Development Studies
Development studies is an interdisciplinary branch of social science. Development studies is offered as a specialized master's degree in a number of universities, and, less commonly, as an undergraduate degree. It has grown in popularity as a subject of study since the early 1990s, and has been most widely taught and researched in the third world and in countries with a colonial history, such as the UK, where development studies originated. Students of development studies often choose careers in international organisations such as the United Nations, World Bank, non-governmental organisations (NGOs), private sector development consultancy firms, corporate social responsibility (CSR) bodies and research centers.
Economics
Economics is a subject that really relates to core aspects of human well-being, and there’s a methodology for thinking about these things. This was a very appealing combination to me. Market systems are capable of massive breakdowns that can result in long, devastating periods of high unemployment. And I felt that economists had really learned something about how to address that.

Economics
How is property given? By restraining liberty; that is, by taking it away so far as necessary for the purpose. How is your house made yours? By debarring every one else from the liberty of entering it without your leave.
