  1. Impact Evaluation Methods in Public Economics: A Brief Introduction to Randomized Evaluations and Comparison with Other Methods

    Dina Pomeranz

    Recent years have seen a large expansion in the use of rigorous impact evaluation techniques. Increasingly, public administrations are collaborating with academic economists and other quantitative social scientists to apply such rigorous methods to the study of public finance. These developments allow for more reliable measurements of the effects of different policy options on the behavioral responses of citizens, firm owners, or public officials. They can help decision makers in tax administrations, public procurement offices, and other public agencies design programs informed by well-founded evidence. This paper provides an introductory overview of the most frequently used impact evaluation methods. It is aimed at facilitating communication and collaboration between practitioners and academics by introducing key vocabulary and concepts used in rigorous impact evaluation methods, starting with randomized controlled trials and comparing them with other methods ranging from simple pre-post analysis to difference-in-differences, matching estimations, and regression discontinuity designs.

  2. No Taxation Without Information: Deterrence and Self-Enforcement in the Value Added Tax

    Dina Pomeranz

    Claims that the VAT facilitates tax enforcement by generating paper trails on transactions between firms contributed to widespread VAT adoption worldwide, but there is surprisingly little evidence. 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. This leads to strong enforcement spillovers up the VAT chain. These findings confirm that when taking evasion into account, significant differences emerge between otherwise equivalent forms of taxation.

  3. Randomized Tax Enforcement Messages: A Policy Tool for Improving Audit Strategies

    Dina Pomeranz, Cristobal Marshall and Pamela Castellon

    Reducing tax evasion is a key challenge for governments around the world, particularly in developing countries. This paper presents a methodology to generate information to optimize audit strategies. Randomly selected taxpayers receive a deterrence message. Comparing their subsequent tax payments to a control group allows estimating what types of taxpayers are more likely to respond to an increase in perceived audit probability. This information can be used to target audits toward taxpayers that respond particularly strongly, and to construct risk indicators to predict taxpayers' responses. We show results from an application in Chile and describe lessons learned during the implementation.

  1. Dodging the Taxman: Firm Misreporting and Limits to Tax Enforcement

    Paul Carrillo, Dina Pomeranz and Monica Singhal

    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 revenues, matching the third-party estimate when provided. Firms also increase reported costs by 96 cents for every dollar of revenue adjustment, resulting in minor increases in total tax collection.

  2. Saving More to Borrow Less: Experimental Evidence from Access to Formal Savings Accounts in Chile

    Felipe Kast and Dina Pomeranz

    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.

  3. Saving More in Groups: Field Experimental Evidence from Chile

    Felipe Kast, Stephan Meier and Dina Pomeranz

    We test the impact of a peer group savings program on precautionary savings through two randomized field experiments among 2,687 microcredit clients. The first experiment finds that the Peer Group Treatment, which combines public goal setting, monitoring in the group, and non-financial rewards, significantly increases savings in a new savings account. The number of deposits grows 3.7-fold, and the average savings balance almost doubles. In contrast, a more classical measure, a substantially increased interest rate, has no effect for most participants and raises the savings balance only for the very top of the distribution. A second experiment, conducted a year later, tests an alternative delivery mechanism and shows that effects of similar size can be achieved through feedback text messages, without meetings, rewards, or peer pressure.

  4. Monitoring Public Procurement: Evidence from a Regression Discontinuity Design in Chile

    Maria Paula Gerardino, Stephan Litschig and Dina D. Pomeranz

    The government is the biggest buyer in the economy of most countries. At the same time, the public procurement process if often thought to be fraught with corruption and malpractice. However, there is little evidence regarding the impact of audits aimed at reducing such malpractice. This paper investigates the effect of being audited on public entities' subsequent procurement practices in Chile. For identification, we exploit a scoring rule of the national auditing agency, which allows for regression discontinuity analysis. Our preliminary results show that the audits seem to lead to a temporary shift towards less transparent modalities of procurement. The share of the amount of total purchases through direct negotiations increases by around 20 percentage points, at the expense of the use of public auctions. The effect is most pronounced during months when the audit is taking place and disappears completely by the subsequent fiscal year. Since audits in Chile rarely happen in consecutive years, and since the audit typically only covers the most recent completed fiscal year, this time pattern of effects is consistent with public agents responding to a temporary drop in audit risk during the year of the audit.

  1. The Promise of Microfinance and Women's Empowerment: What Does the Evidence Say?

    Dina D. Pomeranz

    The microfinance revolution has transformed access to financial services for low-income populations worldwide. As a result, it has become one of the most talked-about innovations in global development in recent decades. However, its expansion has not been without controversy. While many hailed it as a way to end world poverty and promote female empowerment, others condemned it as a disaster for the poor. Female empowerment has often been seen as one of the key promises of the industry. In part, this is based on the fact that more than 80% of its poorest clients, i.e., those who live on less than $1.25/day, are women. This paper discusses what we have learned so far about the potential and limits of microfinance and how insights from research and practice can help inform the industry's current products, policies and future developments.

    Research Summary

  1. Current research

    by Dina D. Pomeranz

    Professor Pomeranz's research is situated at the intersection of development economics and public finance. Her current work focuses in particular on corporate taxation and public procurement, the two key ways in which government finance affects firms and entrepreneurs. Governments globally extract about 20-25% of GDP from the private sector through taxation and pay an average of 10-15% of GDP to firms through public procurement. Whether or not this large share of the economy is managed in a way that creates an equal playing field is therefore of critical importance both for entrepreneurial opportunities and for economic development.

    To study these issues, Professor Pomeranz has conducted large-scale, randomized field experiments, as well as regressin discontinuity analysis and other rigurous research methods using large administrative datasets. In current research, she studies the impact of tax subsidies on firm investment, the effectiveness of international transfer pricing regulation and the role public procurement systems in emerging markets.
  2. Tax evasion

    by Dina D. Pomeranz

    Tax evasion generates billions of dollars of losses in government revenue and creates large distortions, especially in developing countries. A growing, mostly theoretical literature argues that information flows are central to understanding effective taxation. Professor Pomeranz has analyzed the role of information for tax enforcement in the case of the Value Added Tax (VAT) in Chile. She finds that the paper trail generated by the VAT leads to important spillovers in tax enforcement along the production chain. These findings confirm the claim that the VAT has self-enforcing properties, a claim that has contributed to widespread VAT adoption worldwide. They also point to the important role that firms play as aggregators of information, thereby facilitating tax enforcement.
  3. Savings among microentrepreneurs

    by Dina D. Pomeranz

    Poverty is often characterized not only by low average income, but also by highly variable income and expenditures, and by a lack of access to insurance services that can help smooth consumption. While commitment devices such as defaults and direct deposits from wages have been found to be highly effective in increasing savings, they are not available to the millions of people worldwide who work in the informal sector or as independent entrepreneurs, and who therefore do not have a formal wage bill.

    Professor Pomeranz has investigated low-income Chilean microentrepreneurs and found that self-help peer groups can be a highly effective alternative commitment device to encourage savings. Participation in a peer group program increased the number of deposits in formal savings accounts 3.5-fold and almost doubled the average savings balance. A subsequent experiment shows that more than 80 percent of the peer-group effect can be achieved through follow-up by simple text messages. These findings are particularly relevant in light of another study, in which Professor Pomeranz documents that low-income entrepreneurs can effectively use savings accounts for self-insurance and protection against economic shocks.
