This paper focuses on the economic complementarities between labour market institutions, precisely firing costs, employment subsidies and a particular feature of European labour markets, the minimum wage. We investigate a matching model with endogenous job destruction in the tradition of Mortensen and Pissarides [1994]. Workers may be either unemployed, employed in a stable or a subsidised job. Three aspects of the subsidy are studied: its duration, its amount and the proportion of jobs concerned. We show that its efficiency varies according to the way it is financed, the level of firing costs and is lower than without a minimum wage.
