I provide evidence on the effects of financial audit mandates in the charitable sector, in particular their influence on donor behavior. My empirical strategy relies on variation in size‐based exemption thresholds across states and differences in size driven by the nature of charities’ activities. Consistent with audit mandates reducing donors’ reliance on charity reputation, I find audit mandates are associated with a lower concentration of donations on the largest, most well‐known charities. I show this reallocation of resources allows the charitable sector to serve more diverse geographic areas and social needs. In terms of the effect on willingness to give, I document that audit mandates are associated with a higher proportion of taxpayers who donate. However, I only observe a sizable impact on total contributions in dollars for charities with high inherent information asymmetry. Collectively, these results suggest financial audit regulation reduces information frictions and thereby affects resource allocation in the market for charitable giving.

We examine how open procurement data affect the competitiveness of award procedures and the execution of government contracts. The European Union recently made its historical procurement notices available for bulk download in a cohesive and user‐friendly database. Comparing government contracts above and below EU procurement size thresholds, we find that, after the open data initiative, procurement officials are more likely to award treated contracts through open bidding. In cross‐sectional analyses, we document variation in the open bidding effect consistent with two underlying mechanisms: (1) increased scrutiny by NGOs and investigative journalists and (2) learning by national procurement regulators. However, treated contracts are also more likely to experience costly modifications because the shift to open bidding introduces rigidity that limits officials’ discretion in selecting suppliers based on private information. Overall, our evidence indicates that open procurement data promote competitive bidding but lead to contracts with weaker execution performance. These inferences also hold in an alternative open data setting.
