This study explores the effects of state kindergarten-entry-age policies on students’ outcomes by exploiting variation in the kindergarten entry cutoff dates enacted by states in the United States over the last 40 years. Using the state average and standard deviation in NAEP test scores in 4th, 8th and 12th grades, we estimate the impacts of state entry-age policies on educational achievement and test score dispersion in the state. The estimation results from the baseline state and time fixed effects model show that a one month earlier cutoff increases average state reading and math scores of 4th graders by 21.7 and 13.6 percent of a standard deviation, respectively. Eighth graders’ average score increases in math and science are 12.4 and 24.3 percent of a standard deviation, respectively, while the effect on reading score significantly decreases. We find no effect of kindergarten entry date on educational outcomes in 12th grade. We also find that an earlier kindergarten entry date generally reduces the standard deviation of state test scores. Robustness checks support these findings and suggest no evidence of endogeneity of the policy changes. Our findings provide novel evidence that early school start cutoffs have improved state-level achievement measures over the past 40 years.
Using province‐level establishments and employment data from the Korean Employment Insurance Database, this paper investigates how the regional spread of COVID‐19 affects local businesses and unemployment by establishment size and industry. We find that the number of small establishments declines substantially after the COVID‐19 pandemic through a decrease in new establishment creation and a surge in establishment closures. By contrast, large establishments are not affected significantly. Examining the numbers of unemployment benefits (UB) applicants, an indicator of unemployment, we find that the higher the rate of COVID‐19 confirmed cases in a province, the higher the number of UB applicants, regardless of their previous workplace size. Our analysis of employment insurance subscribers further confirms that the regional spread of COVID‐19 leads to a significant reduction in employment and job mobility in small establishments. Regarding industry heterogeneity in the COVID‐19 effects, we find that local COVID‐19 outbreaks affect local industries more through the reduction in establishment creation and new employment than through an increase in establishment closures. Industries that require face‐to‐face operations, such as lodging & restaurant, experience a substantial adverse impact in the early phase, and the impact also tends to last longer as COVID‐19 situations prolong.
Background/Objectives: This research aims to identify any relationships between body dissatisfaction and body size among males in their twenties. Methods: Participants were recruited for a year from August 2015 to July 2016. Participants were 100 males, of which 50 were white American males and 50 were Korean males in North Carolina, United States of America, who are aged between 20 and 29 years old. TC2-19 3D body scanner was used to measure the participant’s body size. A descriptive analysis of data for demographics and body satisfaction was conducted. The data were analyzed by correlation techniques and regression analyses with SPSS 24 for Windows. Results: The results of this research indicate that the participants who have lower BMI, WHR, WCR, or WSR tend to perceive higher evaluations of their appearance, pay more attention to their appearance and are more satisfied with their body areas. Participants who have higher BMI or WHR tend to be more anxious about being overweight. Participants who have lower weight, lower shoulder-to-shoulder and lower girth values tend to show higher AE, AO, and BAS. Participants who have a higher shoulder-to-shoulder, higher upper arm girth, higher chest girth and higher waist tend to have more preoccupation about being overweight. Conclusion/Implications: The results of this research can help fashion businesses consider targeting males’ body dissatisfaction in the design of their products by understanding the relationship between body dissatisfaction and body size of targeting males.
This study estimates the effects of the COVID-19 pandemic on life satisfaction and stress and examines whether these effects vary across different sociodemographic groups using a nationally representative sample in South Korea. We estimate the causal effects of COVID-19 on psychological well-being by exploiting regional variation in the spread of the pandemic in South Korea. While the number of confirmed cases was very small in other provinces in the first half of 2020, the coronavirus spread rapidly in Daegu after an outbreak in one church. We employ a difference-in-differences approach that compares changes in people’s life satisfaction and stress before-and-after the initial surge of COVID-19 cases in Daegu and other provinces. Our results show that the proportion of people who are dissatisfied with life increased by 2.8–6.5 percentage points more in Daegu than in other provinces after the COVID-19 outbreak. During the same period, the proportion of people who reported feeling stressed increased more in Daegu than in other provinces by 5.8–8.9 percentage points. Our results also suggest that the negative impact of the COVID-19 outbreak on psychological well-being is significantly greater for men, young adults, middle-aged adults, self-employed workers, and middle-income individuals. On the other hand, the proportion of people who report feeling stressed among the highest-educated (a master’s degree or higher) and high-income individuals decreased after the onset of the COVID-19 outbreak.
