Liquidity and Mortality of Low-Wage Workers: Evidence from Wage Allowances in Brazil - with Raphael Corbi -  [draft]

• Investigating whether low-income individuals are more likely to face life-threatening events immediately after receiving a payment from the government;

• Because such workers are liquidity-constrained, they do not smooth consumption and increase it immediately after the payment, engaging in behavior that favors mortality, such as substance abuse, eating unhealthy meals, etc;

• Using both a TWFE and RDD approach, we found an increase of 9.5% in mortality counts in the week of payment for eligible workers, when compared to other weeks and non-eligible peers. Deaths were concentrated in causes the medical literature has estabUsing both a TWFE and RDD approach, we found an increase of 9.5\% in mortality counts in the week of payment for eligible workers, when compared to other weeks and non-eligible peers. Deaths were concentrated in causes the medical literature has established a link with excessive consumption.lished a link with excessive consumption.

In Broad Nightlight: The Effects of Ambient Light on Non-violent Crime in Sao Paulo - with Naercio Menezes-Filho

• Studying the impact of a program that increased the level of public lighting in some districts of São Paulo on criminal activity;

• Use of satellite data on nighttime lights to evaluate the size of the intervention;

• Increased level of ambient light has a negative effect on violent crime, but positive on non-violent, due to the increased supply of potential victims that choose to circulate more in better-lit areas;

• Estimated with the new DiD methodology presented by Callaway & Sant'Anna (2020).

Slow and Steady: The Effects of Speed Limit Reductions on the Number of Accidents in the City of Sao Paulo. - with Rodrigo Moita

• Studying the impact of a program decreasing the speed limit of some São Paulo streets in the number of accidents and deaths recorded in them;

• Using a TWFE approach, we find a negative effect on accident counts of speed reduction. This effect is larger in streets in which the speed reduction was larger. Effect disappears if the reduction was reversed at a later date;

• Currently, we're updating the analysis with the new DiD methodologies such as the one presented by Callaway & Sant'Anna (2020).
