Can past informality impede registered firms' access to credit?

Using a large firm-level dataset from the World Bank Enterprise Surveys, which covers 134 countries and includes over 134,000 observations, we examine whether past informality affects the credit constraints of registered firms. Estimations, based on the entropy balancing method, indicate that registered firms that began operations informally are more likely to be credit-constrained than those that started in the formal sector. This finding is extremely robust to a variety of robustness tests, including instrumental variable, propensity score matching, alternative balancing methods that combine weighting and regression, potential omitted variables, restricted samples, alternative measures of credit constraints, different specifications such as Linear Probability, Logit, and Probit models, and clustering standard errors at the country level. Heterogeneity analysis reveals that the detrimental impact of past informality lessens with firm size, firm age, and better structural factors like regulatory quality, trade openness, entrepreneurial dynamism, and public spending. Productivity, competition from the informal sector, and the quality of financial statements are key channels through which past informality increases credit constraints for registered firms.
