A large body of empirical literature indicates that, contrary to predictions from economic theory, wages in the informal sector increase after any minimum wage hike. This phenomenon was so far explained as a byproduct of a signal conveyed by statutory minimum wages to wage setting in the...

We use longitudinal individual wage and employment data in France and the United States to investigate the effect of changes in the real minimum wage rate on an individual?s employment status. We focus on workers employed at wages close enough to the minimum in a reference year as to be illegal...

Using linked employer-employee data for Portugal, we explore an amendment to the minimum wage law which increased from 75% to 100% of the full minimum wage applied to employees younger than 18. Our results show a widening of the gender wage gap following the amendment: the wage gap for minors...

We present a theorem helpful in estimating the mean and variance of a linear function with arbitrary multivariate randomness in its coefficients and variables. We derive a generalized decomposition result from two random linear functions in which the result can be applied to most models using...
