Abstract:
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. Copyright International Atlantic Economic Society 2007
