October 2014Dodging the Taxman: Firm Misreporting and Limits to Tax Enforcement
with Paul Carrillo, Monica Singhal: w20624
Reducing tax evasion is a key priority for many governments, particularly in developing countries. A growing literature has argued that the ability to verify taxpayer self-reports against reports from third parties is critical for modern tax enforcement and the growth of state capacity. However, there may be limits to the effectiveness of third-party information if taxpayers can make offsetting adjustments on less verifiable margins. We present a simple framework to demonstrate the conditions under which this will occur and provide strong empirical evidence for such behavior by exploiting a natural experiment in Ecuador. We find that when firms are notified by the tax authority about detected revenue discrepancies on previously filed corporate income tax returns, they increase reported rev...

June 2014Saving More to Borrow Less: Experimental Evidence from Access to Formal Savings Accounts in Chile
with Felipe Kast: w20239
Poverty is often characterized not only by low and unstable income, but also by heavy debt burdens. We find that reducing barriers to saving through access to free savings accounts decreases participants' short-term debt by about 20%. In addition, participants who experience an economic shock have less need to reduce consumption, and subjective well-being improves significantly. Precautionary savings and credit therefore act as substitutes in providing self-insurance, and participants prefer borrowing less when a free formal savings account is available. Take-up patterns suggest that requests by others for participants to share their resources may be a key obstacle to saving.
July 2013No Taxation without Information: Deterrence and Self-Enforcement in the Value Added Tax
Tax evasion generates billions of dollars of losses in government revenue and creates large distortions, especially in developing countries. Claims that the VAT facilitates tax enforcement by generating paper trails on transactions between firms have contributed to widespread VAT adoption worldwide, but there is little empirical evidence about this mechanism. This paper analyzes the role of third party information for VAT enforcement through two randomized experiments among over 400,000 Chilean firms. Announcing additional monitoring has less impact on transactions that are subject to a paper trail, indicating the paper trail's preventive deterrence effect. Tax enforcement leads to strong spillovers up the VAT chain, increasing compliance by firms' suppliers. These findings confirm that wh...

September 2012Under-Savers Anonymous: Evidence on Self-Help Groups and Peer Pressure as a Savings Commitment Device
with Felipe Kast, Stephan Meier: w18417
We test the effectiveness of self-help peer groups as a commitment device for precautionary savings, through two randomized field experiments among 2,687 microentrepreneurs in Chile. The first experiment finds that self-help peer groups are a powerful tool to increase savings (the number of deposits grows 3.5-fold and the average savings balance almost doubles). Conversely, a substantially higher interest rate has no effect on most participants. A second experiment tests an alternative delivery mechanism and shows that effects of a similar size can be achieved by holding people accountable through feedback text messages, without any meetings or peer pressure.
