The Impact of the Investment Climate on Employment Growth : Does Sub-Saharan Africa Mirror Other Low-Income Regions?
( 2010-02-01)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
( 2009-08-01)Using data on more than 56,000 enterprises in 90 countries, this paper finds that objective conditions in the business environment vary substantially across firms of different sizes and that there are important non-linearities in their impact on employment growth. The paper 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 (less 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. -

Mind the Neighbors : The Impact of Productivity and Location on Firm Turnover
( 2009-10-01)This paper examines the impact of firm productivity and local industrial structure on firm entry and exit in Morocco between 1985 and 2001. There is strong evidence of productivity exerting a market-cleansing role. Less productive firms are found to be more likely to exit - and locations with more productive firms attract higher rates of new firm entry. The effect of productivity operates not only in an absolute sense; a firm s relative productivity or distance to the local sector frontier matters too. First, large productivity gaps are associated with higher rates of exit, while new firms are attracted to locations with small productivity gaps. Second, local competition increases the probability of exit, although it does not encourage entry. Third, there is evidence of scale or agglomeration effects that increase firm turnover. Fourth, measures of sector diversity are not associated with lower turnover. Fifth, the geographic level at which agglomeration and competition effects are defined matters differently for exit than entry. For exit, the provincial measures are strong, while those for communes are weaker. For entry, it is the local productivity at the commune level that is more significant. This implies that competitive pressures are less geographically constrained while the potential benefits of agglomeration and spill-overs are indeed more local.
