Experimental evidence shows that 'rule-of-thumb' accounting training significantly improves the revenues of micro-entrepreneurs with poor financial practices

Micro-entrepreneurs often lack the financial literacy required to make important financial decisions. In this study, the researchers conducted a randomized evaluation with a bank in the Dominican Republic to compare the impact of two distinct programs: standard accounting training versus a simplified, rule-of-thumb training that taught basic financial heuristics. The rule-of-thumb training significantly improved firms’ financial practices, objective reporting quality, and revenues. For micro-entrepreneurs with lower skills or poor initial financial practices, the impact of the rule-of-thumb training was significantly larger than that of the standard accounting training, suggesting that simplifying training programs might improve their effectiveness for less sophisticated individuals.
