The UK's Center for Economic Policy Research, in partnership with the UK's Department for International Development, have launched a 5-year program in Private Enterprise Development for Low-Income Countries (PEDL). PEDL aims to understand market forces and constraints in the world's low-income countries, with attention to cross-cutting themes that include climate and environment (among others). Eligibility extends to researchers from academia, the non-profit sector, think tanks, research centers, and similar. Exploratory Grants (multiple deadlines per year) range from £10 thousand to £35 thousand; the next deadline is 31 March 2012. Major Research Grants (annual) are a minimum of £100 thousand; the deadline is 16 April 2012. Link
