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 United States, which is reflected in higher unconditional rates of entry into the sector. The evidence for Mexico points to the significant presence of well-performing salaried workers among the likely entrants into self-employment, as opposed to the higher incidence of poorer wageworkers among the entrants into the U.S. self-employment sector. Despite these differences, however, the patterns of entry, survival, and growth with respect to age, education, and many other covariates are very similar in Mexico and the United States. These strong similarities suggest that mainstream models of worker decisions and firm behavior are useful guides for policymaking for the developing-country microenterprise sector. Furthermore, they suggest that, as a first approximation, the developing-country microenterprise should probably be viewed as they are in the advanced countries as offering potentially desirable job opportunities to low-productivity workers.

Using firm-level data from Mexico, this paper investigates the firm characteristics associated with participation in credit markets, access to training, tax payments and membership in business associations. We find that firms which participate in these institutions exhibit significantly higher profits. Moreover, firms that borrow from formal or informal sources and those that pay taxes are significantly more likely to stay in business but firms that received credit exhibit lower rates of income growth. These results persist when firm characteristics that are arguably correlated with unobserved entrepreneurial ability are controlled for. Our findings suggest that the significant within-country differences in firm productivity observed in developing economies are due in part to market and government failures that limit the ability of micro-firms to reach their optimal sizes.

This article studies the link between migration, remittances and asset accumulation for a panel of poor rural households in Mexico over the period 1997–2006. In a context of financial markets' imperfections, migration may act as a substitute for imperfect credit and insurance provision (through remittances from migrants) and, thus, exert a positive effect on investment. However, it may well be the case that remittances are channelled towards increasing consumption and leisure goods instead. Exploiting within family variation and an instrumental variable strategy, we show that migration indeed accelerates productive assets' accumulation. However, when we look at the effect of migration on non-productive assets (durable goods), we find a negative effect. Our results then suggest that poor rural families resort to migration as a way to mitigate constraints that prevent them from investing in productive assets.
