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.

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.
