This paper investigates the feasibility of wealth taxation in developing countries. It uses rich administrative data from Colombia and leverages a government-designed program for voluntary disclosures of hidden wealth as well as the threat of detection triggered by the Panama Papers leak. There are two key findings. First, there is substantial (primarily offshore) evasion: two-fifths of the wealthiest 0.01 percent evade taxes, with these evaders concealing one-third of their wealth offshore. Second, strengthening enforcement can have a significant impact on wealth tax compliance, tax revenue, and progressivity. These results highlight both challenges and opportunities for wealth taxation in the developing world. (JEL D31, G51, H24, H26, K34, O15)

How does financial aid affect postsecondary enrollment, college choice, and student composition? We present new evidence based on a large-scale program available to high-achieving, low-income students for attending high-quality colleges in Colombia. RD estimates show financial aid eligibility raised immediate enrollment by 56.5 to 86.5 percent, depending on the complier population. This rise, driven by matriculation at private, high-quality colleges, closed the SES enrollment gap among high achievers. Moreover, a DID approach suggests enrollment of aid-ineligible students also improved because college supply expanded in response to heightened demand. With ability stratification largely replacing SES stratification, diversity increased 46 percent at private, high-quality colleges. (JEL I22, I23, I24, I26, J24, O15)

We study the impact of money on households during theCOVID-19 pandemic. In March 2020, Colombia rolled out a new unconditional cash transfer (UCT) to one million households in povertyworth $19 (PPP $55.6) and paid every 5-8 weeks. Using an RCT and linked administrative and survey data, we find the UCT had positive (albeit modest) effects on measures of household well-being (e.g., financial health, food access). Moreover, the UCT boosted support for emergency assistance to households and firms during the crisis and promoted social cooperation. Finally, we explore the bottlenecks in expanding mobile money during a pandemic.
