We document that in less financially developed economies, small firms grow faster and have lower debt to asset ratios than large firms. We then develop a quantitative model where financial frictions drive firm growth and debt financing through the availability of credit and default risk. We parameterize the model to the firms' financial structure in the data and show that financial restrictions can account for the majority of the difference in growth rates between firms of different sizes across countries.
