The prevention of asymmetric information plays a major role in successful small business lending. The purpose of this research is to determine if small business applicants report their income information correctly when requesting a loan. Therefore, a randomized controlled trial bogus pipeline experiment was set up during a typical cash-flow analysis of a bank for small businesses in the Philippines. Results indicate that loan applicants of the treatment group reported a lower income, an effect which is most pronounced in the lowest income percentile. Moreover, our analyses reveal higher loan delinquencies in the control group.
