This paper estimates the intensive labor supply elasticity in Peru for the 2004-2012 period. During this period the hours worked, as well as the productivity, have followed a decreasing trend while the hourly wage has shown an increasing trend. The labor supply elasticity is around 0.257, and it is heterogeneous according to the workers age, income and educational level. This parameter is also decreasing in the period of analysis, evidence that suggests that changes in the elasticity of labor supply would explain the dynamics of wages in a context of rising productivity.
