Abstract: | A common belief of mainstream economics as well as underpinning government policy is that the more flexible real wage is, the lower is unemployment. In this paper we study the dynamics of a standard neoclassical labour market under the simplest Walrasian adjustment rule. We show that when consumption and leisure are sufficiently low substitutes, an increase in real wage flexibility may destabilize the unique Walrasian equilibrium of the economy, triggering fluctuations in wages and employment. Minimal departures from strict (Walrasian) neoclassical equilibrium modelling are required to obtain instability results for wage flexibility. |
