A rich panel data set from Mexico is used to study the patterns of entry, exit, and growth of microenterprises and to compare these with the findings of the mainstream theoretical and empirical work on firm dynamics. The Mexican self-employment sector is much larger than its counterpart in the...

We analysed labour costs in Mexico and evaluated their impact in terms of firm performance. Using a new survey, we studied how firms chose to conduct a firing procedure (i.e. mandatory payment, negotiation, or legal dispute) and the actual costs derived from that decision. We found that firms...

An additivity property of LM tests is derived, linking joint, marginal and Bera-Yoon `adjusted' tests, hence the latter can be derived as the difference of the first two. An artificial regression framework provides an intuitive geometrical illustration of the Bera-Yoon principle.

Skill premia trends for the Mexican urban labour market are analysed, decomposing into demand and supply factors. Moreover, among the former both between and within effects are studied, in line with the Katz and Murphy decomposition. It is shown that demand factors are more important for...

This paper uses a static spatial banking model with a non-uniform wealth distribution to provide theoretical assessments for differences in banks’ prices and locations across regions. It assumes imperfect information, where banks know more about individuals if they are “near” the bank and...
