Overview

Key facts

London School of Economics and Political Science's Development Economics course will use all the skills you have developed as an economist to try and answer important economic questions. Providing an answer is hard because solving the problem of world poverty is not as simple as reallocating income. It would take $511 billion a year to increase the incomes of the poorest to just $2 a day, but calculated in 2003 the G7 countries aspire to give (but do not quite) just $142 billion a year in aid.

In short, solving world poverty requires finding places where an intervention can generate more in income than it costs. Fortunately the economic theory you already know tells us how to find such places. The economic model you have learned says that if some conditions (X) are met then nothing can be done about poverty without making other people worse off. But we can flip this conclusion on its head: if X is not true, then it is possible to make someone better off without making anyone worse off, and the theory tells us how – make the world more like X. Making progress on poverty means finding out where X does not hold – i.e. where do markets fail?
