The Effect of Obesity and Pregnancy Weight Gain on Maternal and Child Health.

In this study, we estimate the effect of prepregnancy obesity and excessive pregnancy weight gain on infant and maternal health outcomes. We rely on a large sample of maternally linked restricted data from 2004 to 2019 South Carolina birth certificates, which allow us to track the same mothers during multiple pregnancies over a period of more than 15 years. To address possible limitations of previous research, we account for genetic confounders and unobservable maternal and environmental factors by relying on a maternal fixed effects strategy.

The effectiveness of COVID deaths to COVID policies: A robust conditional approach.

This paper examines the effectiveness of four major COVID-19 social distancing policies, (i) shelter-in-place orders (SIPO), (ii) non-essential business closures, (iii) mandatory quarantine for travelers, and (iv) bans on large gatherings, on both COVID cases and COVID deaths. Results indicate that states are highly ineffective in producing the fraction of the population that does not have COVID-19 or the fraction of the population that does not die from COVID-19. We find that having any form of social distancing policies increases the fraction of the population not considered a positive COVID-19 case by 23.

The impact of minimum wage on parental time allocation to children: evidence from the American Time Use Survey.

In this study, using data from the 2003-2019 American Time Use Survey (ATUS), we investigate whether changes in the minimum wage have impacted time allocation to children among low-educated mothers and fathers. Relying on geographic and temporal variation in minimum wage changes across US states, we investigate the impacts of minimum wage increases on total time spent at home with children, time spent on primary childcare, and time spent on enriching childcare activities. Our results indicate that an increase in the minimum wage has a large positive effect on the time low-educated mothers spend on primary childcare and enriching time, with no effect among low-educated fathers.

The efficiency of COVID cases to COVID policies: a robust conditional approach.

This paper examines the efficiency of four major COVID-19 social distancing policies: (i) shelter-in-place orders (SIPO), (ii) non-essential business closures, (iii) mandatory quarantine for travelers, and (iv) bans on large gatherings. Results suggest that the average US state is highly inefficient in producing the fraction of the population that does not have COVID-19 without social distancing policies put in place. We find that having any of the four major social distancing policies increases conditional efficiency by 9.

No theory: an explanation of the lack of consistency in cross-country health care comparisons using non-parametric estimators.

Since 2000 several papers have examined the efficiency of healthcare delivery systems worldwide. These papers have extended the literature using drastically different input and output combinations from one another, with little theoretical or empirical support backing these specifications. Issues arise that many of these inputs and outputs are available for a subset of OECD countries each year.
