Self-enforcing labour contracts and macroeconomic dynamics

To properly account for the dynamics of the key macroeconomic variables, researchers incorporate various internal propagation mechanisms in their models. In general, these mechanisms implicitly rely on the assumption of a perfect equality between the real wage and the marginal product of labour. This paper features a micro-founded model of a limited-commitment firm, and derive endogenous dynamic labour contracts that produce a different linkage between the real wage and the marginal product of labour. The risk-sharing between the entrepreneur and the worker, both faced with enforcement problems, provides a different type of propagation mechanism. I investigate the dynamic properties of this endogenous rigidity in relation to the initial bargaining power of each agent. © International Atlantic Economic Society 2007.
