One of the explanations for global imbalances is the self-financing behavior of credit-constrained firms in rapidly growing emerging markets. We use an extensive firm-level data set from several Asian countries during 2002–2011, and test the micro foundation of this theory by estimating the effect of an exogenous change in credit constraints, resulting from financial reforms, on firms’ saving behavior. As predicted, after financial reforms, firms who were credit-constrained previously decreased their savings more (or increased their savings less) relative to unconstrained firms.
