This article examines the labour market for day labourers in the Southern Low Countries during the eighteenth century from the perspective of reciprocal exchange. In particular I will look at wage payment structures and their economic and social foundations. In contrast with other agricultural regions, wage payments in proto-industrialized inland Flanders were highly diversified. Large farmers and day labourers engaged in a system of reciprocal exchange of labour, goods and services in which monetary payments played only a secondary role. I find that both employers and employees had strong reasons for maintaining this exchange relationship and that they both, in their own ways, benefited from this mutual dependency.
