The labour market in a dual economy: Another look at colonial Rhodesia

A labour market model is developed for the formal sector of a labour surplus economy, allowing for monopsony power by firm owners and an inelastic supply of labour with respect to the wage rate. This inelasticity arises even though the wage rate in the traditional sector may be ‘fixed’ due to surplus land, and the supply of labour to the traditional sector responds quite positively to an exogenous increase in the (implicit) wage rate there. This labour supply function is derived from a simple utility maximisation model incorporating the spatial aspects of temporary migration to the formal sector.
