AbstractThis paper examines distance‐based effects of the introduction of a National Basketball Association (NBA) team on establishment‐level sales. Using a unique micro dataset with precise geographic location information and industry detail, we apply spatio‐temporal estimation strategies following Harger et al. and Ahlfeldt and Kavetsos. We build on the literature by focusing on sales activity, a broad measure of economic activity, for industries related to the NBA‐product. Our application considers the relocation of the NBA's Seattle franchise (Supersonics) to Oklahoma City (Thunder). The results reveal spatially differentiated impacts that would be obscured using data aggregated over space or industry. Specifically, food establishments exhibit increased sales and entertainment establishments exhibit decreased sales relative to establishments in the outer most ring of the study area.

Abstract
Currently, sales taxes are imposed at both the state and local levels in 37 US states. In these environments, vertical tax competition occurs as governments share a common sales tax base, and local jurisdictions have autonomy over sales tax rates. As cash-strapped states look to sales taxes for additional revenues, local governments may worry about potentially adverse revenue impacts, as consumers react to combined tax rate increases. This study examines state-municipal and county-municipal fiscal spillovers using an empirical approach that accounts for endogenous tax policy leadership and voter tax fatigue. Employing comprehensive longitudinal data from Oklahoma, we find that state tax hikes significantly crowd out future rate increases for the large group of jurisdictions that are designated as followers. Leader jurisdictions are not found to display crowd-out tendencies, a result that is consistent with recent work suggesting that leaders may be less influenced by vertical fiscal externalities than other jurisdictions.

Abstract
This study investigates whether and how energy consumers respond to public appeals for voluntary conservation during an extended and extreme winter energy emergency. Public appeals are an increasingly important tool for managing demand when grid disruptions are anticipated, especially given the increase in severe-weather events. We add to the few studies on winter energy crises by investigating a case in which there were repeated public appeals during an extended event. Using a survey implemented via social media immediately after the February 2021 winter storm, we asked residents of Norman, Oklahoma, a series of questions about their responses to the public appeals distributed by the utility company, including whether they followed the actions suggested in the messages as well as where they got information and their level of concern about the storm impacts. We compare mean responses across a range of categorical answers using standard independent t tests, one-way ANOVA tests, and chi-squared tests. Among the 296 respondents, there was a high degree of reported compliance, including setting the thermostat to 68°F (20°C) or lower (72%), avoiding using major appliances (86%), and turning off nonessential appliances, lights, and equipment (89%). Our findings suggest a high degree of willingness to voluntarily reduce energy consumption during an energy emergency. This is encouraging for energy managers: public appeals can be disseminated via social media at a low cost and in real time during an extended emergency event.

Significance Statement
The purpose of this study is to better understand whether and how energy consumers respond to public appeals for voluntary conservation during a winter energy emergency event. This is important because voluntary conservation can help utility managers minimize grid disruptions, particularly if consumers respond to evolving conditions. Our survey results suggest that individuals are willing to voluntarily conserve energy and follow conservation recommendations provided by utility managers during a severe winter event.

Abstract
This study examines how individuals' trust levels and patience are affected by a tornado event. Affected and unaffected people were surveyed after a 2013 tornado in Moore, Oklahoma, that resulted in 24 fatalities. Findings suggest that those who self-identified as affected became more trusting in general as well as more trusting of police and fire authorities. Affected homeowners also exhibited less patience than their unaffected counterparts. The evaluation of differences in trust and patience enables us to learn about how underlying propensities to invest (or reinvest) in critical private and public infrastructure may be influenced by extreme events. Disasters alter trust levels and patience of affected residents, and documenting the direction and magnitude of these changes may help agencies involved in the recovery process.

AbstractPregnant women in poverty may be especially likely to experience sleep and circadian rhythm disturbances, which may have downstream effects on fetal neurodevelopment. However, the associations between sleep and circadian rhythm disturbances, social disadvantage during pregnancy, and neonatal brain structure remains poorly understood. The current study explored the association between maternal sleep and circadian rhythm disturbances during pregnancy and neonatal brain outcomes, examining sleep and circadian rhythm disturbances as a mediator of the effect of social disadvantage during pregnancy on infant structural brain outcomes. The study included 148 mother‐infant dyads, recruited during early pregnancy, who had both actigraphy and neuroimaging data. Mothers' sleep was assessed throughout their pregnancy using actigraphy, and neonates underwent brain magnetic resonance imaging in the first weeks of life. Neonatal structural brain outcomes included cortical gray matter, subcortical gray matter, and white matter volumes along with a measure of the total surface area of the cortex. Neonates of mothers who experienced greater inter‐daily deviations in sleep duration had smaller total cortical gray and white matter volumes and reduced cortical surface areas. Neonates of mothers who had higher levels of circadian misalignment and later sleep timing during pregnancy showed smaller subcortical gray matter volumes. Inter‐daily deviations in sleep duration during pregnancy mediated the association between maternal social disadvantage and neonatal structural brain outcomes. Findings highlight the importance of regularity and rhythmicity in sleep schedules during pregnancy and bring to light the role of chronodisruption as a potential mechanism underlying the deleterious neurodevelopmental effects of prenatal adversity.Research Highlights
Social disadvantage was associated with sleep and circadian rhythm disturbances during pregnancy, including later sleep schedules, increased variability in sleep duration, circadian misalignment, and a higher proportion of the sleep period spent awake.
Maternal sleep and circadian rhythm disturbances during pregnancy were associated with decreased brain volume and reduced cortical surface area in neonates.
Maternal inter‐daily deviations in sleep duration during pregnancy mediated the association between social disadvantage and neonatal brain volume and cortical surface area.
