This paper studies the role of technology in local-government tax collection capacity in the developing world. We first conduct a new census of all local governments in Ghana to document a strong association between technology use and property tax billing, collection and enforcement. We then...

We show how to use field-programmable gate arrays (FPGAs) and their associated high-level synthesis (HLS) compilers to solve heterogeneous agent models with incomplete markets and aggregate uncertainty (Krusell and Smith, 1998). We document that the acceleration delivered by one single FPGA is...

The philanthropic sector is highly consequential, particularly in the United States, and the most important policies directed toward this sector are tax policies. Yet most economic analysis of the optimal tax treatment of charitable giving is ad hoc, treating it as a subject unto itself. This...

We assess the business provisions of the 2017 Tax Cuts and Jobs Act, the biggest corporate tax cut in US history. We draw five lessons. First, corporate tax revenue fell by 40 percent due to the lower rate and more generous expensing. Second, firms with larger declines in their effective tax...

In the second half of the 2010s more than 100 countries--including all large offshore financial centers--started to automatically exchange bank information with foreign tax authorities. This informational big-bang marks a break with the situation of offshore bank secrecy that prevailed before....

Do perceptions about how the government spends tax dollars affect the willingness to pay taxes? We designed a field experiment to test this hypothesis in a natural, high-stakes context and via revealed preferences. We measure perceptions about the share of property tax revenues that fund public...

Property taxes in developing countries are plagued by noncompliance and can exacerbate liquidity constraints. We characterize optimal enforcement and taxation policies as functions of revenue elasticities and measures of taxpayer hardship. We estimate these parameters using multiple sources of...

Are firms sophisticated maximizers, or do they consistently make errors? Using transaction-level data from Ugandan value-added tax (VAT) returns, we show that sellers and buyers report different amounts 79% of the time, despite invoices being easily cross-checked. We estimate that 25% of firms...

We examine two Pakistani programs to explore the role of deterrence as well as social and psychological factors in the tax compliance behavior of agents. In the first of these programs, the government began revealing income tax paid by every taxpayer in the country. The second program publicly...

Between 2020 and 2029, the IRS will fail to collect nearly $7.5 trillion of taxes it is due. It is not possible to calculate with precision how much of this "tax gap" could be collected. This paper offers a naïve approach. The analysis suggests that with feasible changes in policy, the IRS...
