Chasing the shadow: unreported wage payments and income inequality
摘要
We develop a novel way to evaluate the size of unreported wage payments at employee level. It is only the reported employer-employee income data combined with firm-level financial statements and survey information on various person-level indicators that are required for this purpose. We estimate the Mincer earning regression by the Stochastic Frontier Analysis approach, proxying the unreported wage payments by the non-negative inefficiency term. Our methodology is tested on the Latvian data: we find that unofficial payments to employees with small reported wages are more frequent and sizeable, revealing lower wage inequality in Latvia when the unreported wage is taken into account.
