We develop a framework to conduct experiments for estimating direct and spillover effects when units are grouped into mutually exclusive clusters. Crucially, our framework accounts for heterogeneous treatment effects across clusters and heterogeneous cluster sizes, which are pervasive in...

The demonetisation exercise announced by the PM on November 8, 2016, aimed to tackle the problems of black money, fake currency, corruption, and terror funding. With time, more targets were added such as the creation of a cashless economy, curbing real estate prices, and broadening the taxpayer...

We set up a framework to conduct experiments for estimating spillover effects when units are grouped into mutually exclusive clusters. We improve upon existing methods by allowing for heteroskedasticity, intra-cluster correlation and cluster size heterogeneity, which are typically ignored when...

Tax evasion is a pervasive problem in many countries. In particular, some developing countries do not collect even half of what they would if taxpayers complied with the written letter of the law. The academic literature has not been oblivious to the need to explain why people pay (or do not...

This paper studies the first large scale effort by the Brazilian government to increase the social security compliance of self-employed workers using behavioral interventions. In 2014, the Brazilian Ministry of Social Security gradually delivered by postal mail a booklet reminding nearly 3...

Simplified tax regimes reduce both tax rates and compliance costs for small firms. On the one hand, these regimes increase the number of businesses formally registered and have the potential of also expanding the safety net when they subsidize the contributions to social security of workers in...

What happens when the tax authority increases enforcement in one tax with compliance in other taxes? The very little evidence available is not conclusive. This paper presents a very simple analytical model that shows the conditions under which spillovers could be positive or negative in the...

Governments in Latin America raise little revenue from property taxation, despite arguments for its efficiency and equity. Adequate registry information would support consistent collection, but registries are costly to establish and maintain. Compared to tax collection, field experimental...

Many countries worldwide face significant miss reporting in tax declarations. Miss reporting leads to undesired low revenue and economic distortions. This paper discusses the extent to which the residual bookkeeping burden faced by small firms in simplified regimes influence tax declarations. A...
