The laws that regulate relations between firms and workers in Mexico distinguish sharply between salaried and non-salaried workers, and they are at the root of the existence of informality. This paper provides a clear definition of informality, distinguishing it from illegality. Using Mexico's Economic Census, the paper shows that the majority of firms are informal but legal, that there are more small formal firms than large ones, and that some large firms are informal. It also shows that informality and illegality increased in the period [1998][1999][2000][2001][2002][2003][2004][2005][2006][2007][2008]. Using a simple model of monopolistic competition to measure the productivity losses due to distortions that misallocate resources, the paper finds that one peso of capital and labor allocated to formal and legal firms is worth 28 percent more than if allocated to illegal and informal firms, and 50 percent more than if allocated to legal and informal firms. The paper concludes arguing that the distortions in the labor market created by informality reduce total factor productivity. Terms of use: Documents in JEL classifications: D24, O47, L25

However, average workers' earnings have stagnated and earnings for workers with more schooling have declined, compressing the earnings distribution and lowering the returns to education. We hypothesize that these developments are explained by large and persistent of distortions that misallocate resources towards less productive firms, since these firms are substantially less intensive in educated workers than more productive ones. We show that at the same time that the relative supply of workers with more years of schooling has increased, misallocation of resources toward less productive firms has persisted. These two trends have generated a widening mismatch between the supply and demand for educated workers. We decompose worker earnings into observable and unobservable firm and individual worker characteristics, and simulate a counterfactual earnings distribution in the absence of misallocation. Under the counterfactual, earnings differentials across schooling levels would increase, as would the returns to education. In parallel, earnings differentials, rather than narrowing overtime, would widen. We conclude arguing that the persistence of distortions that misallocate resources toward low...
