Analyzes labour markets from the a perspective that employers have significant market (or monopsony) power over their workers. Arguing that this power derives from frictions in the labour market that make it time-consuming for workers to change jobs, this book examines much of labor economics based on this alternative assumption.

In a monopsonistic labour market, concludes Manning, the 'free' market can no longer be sustained as an ideal and labour economists need to be more open-minded in their evaluation of labour market policies. "Monopsony in Motion" will represent for some a new fundamental text in the advanced study of labour economics, and for others, an invaluable alternative perspective that henceforth must be taken into account in any serious consideration of the subject.
