Towards better evidence for market systems initiatives

We often hear calls for more rigorous evidence. But what does 'rigour' mean, particularly in the case of market systems initiatives? 

Elise Wach explores what makes evidence rigorous and the extent to which such evidence exists for market systems programmes, drawing on interviews, ediscussion and theory. The thinkpiece lays out what is understood to constitute rigour, and suggests ways in which improved evidence could be generated. It is not ‘just another paper about methods’, but focuses on other crucial elements that affect rigour, including the scope of assessments and organisational cultures.
