In a competitive model we ease the assumption that efficiency units of labour are the product of hours and workers. We show that a minimum wage may either increase or decrease hours per worker and the change will have the opposite sign to the slope of the equilibrium hours hourly wage locus....

We develop a model where workers may enter self-employment or search for jobs as employees and where there is heterogeneity across workers' managerial ability. Workers with higher skills will manage larger firms while workers with low managerial ability will run smaller firms and will be in...

We use an equilibrium search framework to model a formal- informal sector labour market where the informal sector arises endogenously. In our model large firms will be in the formal sector and pay a wage premium, while small firms are characterised by low wages and tend to be in the informal...

I argue that in contrast to the literature to date efficiency wage and bargaining solutions will typically be independent. If the bargained wage satisfies the efficiency wage constraint efficiency wages are irrelevant. If it does not, typically we have the efficiency wage solution and bargaining...
