    Does Expanding Health Insurance beyond Formal-Sector Workers Encourage Informality? Measuring the Impact of Mexico’s Seguro Popular
    (2011-08-01) Aterido, Reyes; Hallward-Driemeier, Mary; Pages, Carmen
    Seguro Popular was introduced in 2002 to provide health insurance to the 50 million Mexicans without Social Security. This paper tests whether the program has had unintended consequences, distorting workers' incentives to operate in the informal sector. The analysis examines the impact of Seguro Popular on disaggregated labor market decisions, taking into account that program coverage depends not only on the individual's employment status, but also that of other household members. The identification strategy relies on the variation in Seguro Popular's rollout across municipalities and time, with the difference-in-difference estimation controlling for household fixed effects. The paper finds that Seguro Popular lowers formality by 0.4-0.7 percentage points, with adjustments largely occurring within a few years of the program's introduction. Rather than encouraging exit from the formal sector, Seguro Popular is associated with a 3.1 percentage point reduction (a 20 percent decline) in the inflow of workers into formality. Income effects are also apparent, with significantly decreased flows out of unemployment and lower labor force participation. The impact is larger for those with less education, in larger households, and with someone else in the household guaranteeing Social Security coverage. However, workers pay for part of these benefits with lower wages in the informal sector.

    The Impact of the Investment Climate on Employment Growth : Does Sub-Saharan Africa Mirror Other Low-Income Regions?
    (2010-02-01) Aterido, Reyes; Hallward-Driemeier, Mary
    Using survey data from 86,000 enterprises in 104 countries, including 17,000 enterprises in 31 Sub-Saharan African countries, this paper finds that average enterprise-level employment growth rates are remarkably similar across regions. This is true despite significant differences in the quality of the investment climate in which these enterprises operate. Objective measures of investment climate conditions (including the number of outages, the share of firms with bank loans, and others) indicate that conditions are most challenging within Sub-Saharan Africa, as well as for smaller enterprises. However, enterprises employment in Sub-Saharan Africa is less sensitive to changes in access to infrastructure and finance relative to other low-income regions. This can be understood by looking at non-linear effects by firm size -- and the finding that these size effects are particularly strong within Sub-Saharan Africa. Although unreliable infrastructure services and inadequate access to finance generally hamper growth, in Sub-Saharan Africa they are actually associated with higher employment growth rates among micro enterprises. Although employment growth is good news in Sub-Saharan Africa, that much of the expanded employment is in small, labor-intensive, less productive enterprises raises longer-run concerns about the efficiency of the allocation of resources and aggregate productivity growth in the region.

    Big Constraints to Small Firms' Growth? Business Environment and Employment Growth across Firms
    (2011) Aterido, Reyes; Hallward-Driemeier, Mary; Pages, Carmen
    Using data on more than 56,000 enterprises in 90 countries, this study finds that objective conditions in the business environment vary substantially across firms of different sizes and that there are important nonlinearities in their impact on employment growth. The study focuses on four areas: access to finance, business regulations, corruption, and infrastructure. The results, particularly on the impacts of finance and corruption on growth, depend on whether and how the analysis accounts for the possible endogeneity of the business environment. Controlling for endogeneity revises the finding that small firms benefit most from access to finance, particularly for sources of finance associated with investment and growth. The findings are also sensitive to how "small" is defined. Differentiating micro (fewer than 10 employees) from other small firms shows that, while small firms can be disadvantaged in such an environment, micro firms tend to be proportionally less affected by a weak business climate--and, on occasion, it can help them to grow. Overall, allowing different size classifications provides insights into the impact of the business environment that are lost in more aggregate analyses.
