Within-job gender pay inequality in 15 countries.

Extant research on the gender pay gap suggests that men and women who do the same work for the same employer receive similar pay, so that processes sorting people into jobs are thought to account for the vast majority of the pay gap. Data that can identify women and men who do the same work for the same employer are rare, and research informing this crucial aspect of gender differences in pay is several decades old and from a limited number of countries. Here, using recent linked employer-employee data from 15 countries, we show that the processes sorting people into different jobs account for substantially less of the gender pay differences than was previously believed and that within-job pay differences remain consequential.

Review of Internet of Things-Based Artificial Intelligence Analysis Method through Real-Time Indoor Air Quality and Health Effect Monitoring: Focusing on Indoor Air Pollution That Are Harmful to the Respiratory Organ.

Everyone is aware that air and environmental pollutants are harmful to health. Among them, indoor air quality directly affects physical health, such as respiratory rather than outdoor air. However, studies that have examined the correlation between environmental and health information have been conducted with public data targeting large cohorts, and studies with real-time data analysis are insufficient. Therefore, this research explores the research with an indoor air quality monitoring (AQM) system based on developing environmental detection sensors and the internet of things to collect, monitor, and analyze environmental and health data from various data sources in real-time. It explores the usage of wearable devices for health monitoring systems. In addition, the availability of big data and artificial intelligence analysis and prediction has increased, investigating algorithmic studies for accurate prediction of hazardous environments and health impacts. Regarding health effects, techniques to prevent respiratory and related diseases were reviewed.

Singlehood in contemporary Japan: Rating, dating, and waiting for a good match.

BACKGROUND: Late age at marriage and rising rates of singlehood increasingly characterize East Asian societies. For Japan, these are major contributors to the very low birth rate. OBJECTIVE: We analyze two unique data sets: dating records covering a two-year period from one of Japan's largest marriage agencies and in-depth interviews with 30 highly-educated Japanese singles. The longitudinal nature of the quantitative data allows us to test hypotheses about how single men's and women's preferences for partners' characteristics adjust over time. The qualitative data provides a more fine-grained look at Japanese singles' partner preferences. METHODS: We employ fixed-effects regression models to analyze Japanese men's and women's preferences for the relative and absolute education, income, and age of potential marriage partners. RESULTS: Both the quantitative and qualitative data suggest that Japanese women continue to highly value men's income-earning capacity. Men, in contrast, value a partner with moderate income-earning potential. Women's and men's preferences for partner's education are somewhat weaker, and women broaden their educational preference over time. CONCLUSION: Japanese men's and women's preferences for a potential partner's characteristics are largely consistent with Becker's theory of gender-role specialization. But we also find evidence consistent with Oppenheimer's expectation that men are coming to value women's income-earning capacity more highly than in the past. CONTRIBUTION: We use a unique Japanese data set featuring dating records over a two-year period to examine the appropriateness of theories of marital sorting proposed by Becker and Oppenheimer. Our quantitative analysis is complemented by in-depth interviews with Japanese singles.

Rising between-workplace inequalities in high-income countries.

It is well documented that earnings inequalities have risen in many high-income countries. Less clear are the linkages between rising income inequality and workplace dynamics, how within- and between-workplace inequality varies across countries, and to what extent these inequalities are moderated by national labor market institutions. In order to describe changes in the initial between- and within-firm market income distribution we analyze administrative records for 2,000,000,000+ job years nested within 50,000,000+ workplace years for 14 high-income countries in North America, Scandinavia, Continental and Eastern Europe, the Middle East, and East Asia. We find that countries vary a great deal in their levels and trends in earnings inequality but that the between-workplace share of wage inequality is growing in almost all countries examined and is in no country declining. We also find that earnings inequalities and the share of between-workplace inequalities are lower and grew less strongly in countries with stronger institutional employment protections and rose faster when these labor market protections weakened. Our findings suggest that firm-level restructuring and increasing wage inequalities between workplaces are more central contributors to rising income inequality than previously recognized.
