Head Start Funding Expansions and Program Inputs

Wed, 14 Feb 2024 00:00:00 +0000

This paper provides some of the first evidence on the relationship between Head Start funding expansions and program inputs. We take advantage of the county–year variation in funding increases that were implemented due to a number of legislated policy changes in the late 1980s and throughout the 1990s. By focusing on the period between 1988 and 2007, we show that the funding increases were directed at increasing total and full-time enrollment. We also show that the funding expansions were used to make several quality-related investments, including increasing the number of teachers and staff and upgrading the skill level of teachers.

Safe-zone schools and the academic performance of children in mixed-status households: Evidence from the between the lines study.

Sat, 13 Jan 2024 00:00:00 +0000

In response to the intensification of immigration enforcement in the interior of the USA, some school districts have implemented safe-zone policies to protect students academic progression and well-being. Using primary data from a sample of US-born children of unauthorized migrants, we document the detrimental effect of stricter immigration enforcement on childrens educational outcomes and the benefits of safe-zone policies. Our analyses show that restricting immigration authorities access to schools and providing counseling on immigration-related issues are crucial policy components in strengthening childrens focus, effort, expectations, parental involvement, and relationships. These findings highlight the damaging impact of immigration enforcement on US-citizen children in mixed-status households and advance our understanding of the role of local policies in mitigating these effects.

Schooling and Parental Labor Supply: Evidence from COVID-19 School Closures in the United States

Mon, 14 Aug 2023 00:00:00 +0000

This article examines changes in parental labor supply in response to the unanticipated closure of schools following the onset of the COVID-19 pandemic in the United States. The authors collect detailed daily information on school closures at the school-district level, which they merge to individual-level data on labor supply and sociodemographic characteristics from the monthly Current Population Survey spanning from January 2019 through May 2020. Using a difference-in-differences estimation approach, the authors find evidence of non-negligible labor supply reductions. Having a partner at home helped offset the negative effect of school closures, particularly for maternal employment, although respondents' job traits played a more significant role in shaping labor supply responses to school closures. Overall, the labor supply impacts of school closures prove robust to identification checks and to controlling for other coexistent social distancing measures. In addition, these early...

The next phases of the Migrante Project: Study protocol to expand an observatory of migrant health on the Mexico—U.S. border

Tue, 18 Jul 2023 00:00:00 +0000

Background: Mexican migrants traveling across the Mexico-United States (U.S.) border region represent a large, highly mobile, and socially vulnerable subset of Mexican nationals. Population-level health data for this group is hard to obtain given their geographic dispersion, mobility, and largely unauthorized status in the U.S. Over the last 14 years, the Migrante Project has implemented a unique migration framework and novel methodological approach to generate population-level estimates of disease burden and healthcare access for migrants traversing the Mexico-U.S. border. This paper describes the rationale and history of the Migrante Project and the protocol for the next phases of the project. Methods/design: In the next phases, two probability, face-to-face surveys of Mexican migrant flows will be conducted at key crossing points in Tijuana, Ciudad Juarez, and Matamoros (N = 1,200 each). Both survey waves will obtain data on demographics, migration history, health status,...

Timing of social distancing policies and COVID-19 mortality: county-level evidence from the U.S.

Tue, 20 Jun 2023 00:00:00 +0000

Using county-level data on COVID-19 mortality and infections, along with county-level information on the adoption of non-pharmaceutical interventions (NPIs), we examine how the speed of NPI adoption affected COVID-19 mortality in the United States. Our estimates suggest that adopting safer-at-home orders or non-essential business closures 1 day before infections double can curtail the COVID-19 death rate by 1.9%. This finding proves robust to alternative measures of NPI adoption speed, model specifications that control for testing, other NPIs, and mobility and across various samples (national, the Northeast, excluding New York, and excluding the Northeast). We also find that the adoption speed of NPIs is associated with lower infections and is unrelated to non-COVID deaths, suggesting these measures slowed contagion. Finally, NPI adoption speed appears to have been less effective in Republican counties, suggesting that political ideology might have compromised their efficacy.

Health Profile and Health Care Access of Mexican Migration Flows Traversing the Northern Border of Mexico

Tue, 6 Jun 2023 00:00:00 +0000

BACKGROUND: The health of Latino migrants is most often studied with samples of immigrants settled in the United States or returned migrants in Mexico. We examine health outcomes and health care access of Mexican migrants traversing the Mexican border region to gain a better understanding of migrant health needs as they transition between migration phases. METHODS: We used data from a 2013 probability survey of migrants from Northbound and Southbound migration flows in Tijuana, Mexico (N=2412). Respondents included Northbound migrants with and without US migration experience, Southbound migrants returning home from the United States or the Mexican border region, and migrants returning to Mexico via deportation. Descriptive statistics and regression models were estimated to characterize and compare their health status, behavioral health, and health care access across migration phases. RESULTS: Northbound migrants with US migration experience, Southbound migrants from the United...

How Do Travel Costs Shape Collaboration?

Thu, 17 Feb 2022 00:00:00 +0000

We develop a simple theoretical framework for thinking about how geographic frictions, and in particular travel costs, shape scientists’ collaboration decisions and the types of projects that are developed locally versus over distance. We then take advantage of a quasi-experiment—the introduction of new routes by a low-cost airline—to test the predictions of the theory. Results show that travel costs constitute an important friction to collaboration: after a low-cost airline enters, the number of collaborations increases between 0.3 and 1.1 times, a result that is robust to multiple falsification tests and causal in nature. The reduction in geographic frictions is particularly beneficial for high-quality scientists that are otherwise embedded in worse local environments. Consistent with the theory, lower travel costs also endogenously change the types of projects scientists engage in at different levels of distance. After the shock, we observe an increase in higher-quality and...

Early adoption of non-pharmaceutical interventions and COVID-19 mortality

Mon, 17 May 2021 00:00:00 +0000

To contain the spread of the COVID-19 pandemic, many countries around the globe have adopted social distancing measures. Yet, establishing the causal effect of non-pharmaceutical interventions (NPIs) is difficult because they do not occur arbitrarily. We exploit a quasi-random source of variation for identification purposes -namely, regional differences in the placement on the pandemic curve following an unexpected and nationwide lockdown. Our results reveal that regions where the outbreak had just started when the lockdown was implemented had 1.62 fewer daily deaths per 100,000 inhabitants when compared to regions for which the lockdown arrived 10+ days after the pandemic's outbreak. As a result, a total of 4,642 total deaths (232 deaths/daily) could have been avoided by the end of our period of study -a figure representing 23% of registered deaths in Spain at the time. We rule out differential pre-COVID mortality trends and self-distancing behaviors across the compared regions...

Motivating Whistleblowers

Thu, 11 Jun 2020 00:00:00 +0000

Law-breaking activities within firms are widespread but difficult to uncover, making whistleblowing by employees desirable. We investigate if and how monetary incentives and expectations of social approval or disapproval from the public, and their interactions, affect an employee’s decision to blow the whistle when the social damage from the reported misbehavior is more or less salient. Our analysis also has implications for the design and management of firms’ internal whistleblowing channels. This paper was accepted by Yan Chen, decision analysis.

Strategies to customize responsible gambling messages: a review and focus group study

Thu, 21 May 2020 00:00:00 +0000

BackgroundResponsible gambling messages are widely used as a tool to enable informed choice and encourage appropriate gambling behavior. It is generally accepted that gamblers have different levels of risk of developing gambling problems and require various harm minimization tools and resources. Therefore, it is reasonable to expect that responsible gambling messages should be customized and target specific groups of gamblers. This project aimed to understand hypothesized differences between cohorts of gamblers and receive qualitative feedback on archetypal targeted messages used to increase use of responsible gambling tools.MethodsFocus groups were held to test messages for specific cohorts: young adults (18–24 years), seniors (60+ years), frequent gamblers (weekly), and gamblers of skill-based games (poker, sports betting).ResultsCohorts exhibited different preferences and responses to message archetypes. Seniors preferred messages about limit setting, whilst young adults and...

Does Science Advance One Funeral at a Time?

Tue, 28 Apr 2020 00:00:00 +0000

We examine how the premature death of eminent life scientists alters the vitality of their fields. While the flow of articles by collaborators into affected fields decreases after the death of a star scientist, the flow of articles by non-collaborators increases markedly. This surge in contributions from outsiders draws upon a different scientific corpus and is disproportionately likely to be highly cited. While outsiders appear reluctant to challenge leadership within a field when the star is alive, the loss of a luminary provides an opportunity for fields to evolve in new directions that advance the frontier of knowledge.
