Causes of Indonesia’s Forest Fires
New research features a 30,000-village case study of the 2015 fire season on Sumatra and Kalimantan and asks which villages, for a given level of spatial fire risk, are more likely to have fire.
Do Immigrants Assimilate More Slowly Today Than in the Past?
Using millions of historical census records and modern birth certificates, new research documents that immigrants assimilated into U.S. society at similar rates in the past and present.
Gross Ecosystem Product (GEP) is an aggregate measure of the monetary value of final ecosystem services, or the direct benefits that people derive from nature. In this study, we focus on the 'Chang-Zhu-Tan' (CZT) urban agglomeration—an emerging megacity of over 15 million people situated on the Yangtze River—as a case study of the dynamics of ecological production amidst rapid urbanization. In this study, we couple a spatial-temporal analysis of regional ecological change based on remote-sensing data with economic valuation methods (e.g. travel cost method) using official statistics and survey data. We find that while the land cover of natural ecosystems decreased slightly between 2000 and 2015, their quality—and therefore economic value—greatly improved. From 2000 to 2015, the GEP of CZT increased by 56.77%. In particular, the value of regulating services grew by 7.43% (calculated using inflation-adjusted prices). GEP can reflect nature's contribution to human well-being. At the same time, its long-term trends can serve as an indicator of the extent and quality of local and regional ecosystems, thereby providing a corrective or complement to more conventional measures of development. Although urbanization increases spatial constraints on the management of natural capital, progress in ecological protection and restoration can still improve the quality of ecosystems and the services they provide. Our study shows how GEP, and the value of natural capital it reflects, can grow amidst the pressures of rapid urbanization.

This paper studies how the COVID-19 pandemic has affected labor demand using over 100 million posted jobs on one of the largest online platforms in China. Our data reveals that, due to the effects of the pandemic both in China and abroad, the number of newly posted jobs within the first 13 weeks after the Wuhan lockdown on January 23, 2020 was about one third lower than that of the same lunar calendar weeks in 2018 and 2019. Using econometric methods, we show that, via the global supply chain, COVID-19 cases abroad and in particular pandemic-control policies by foreign governments reduced new job creations in China by 11.7%. We also find that Chinese firms most exposed to international trade outperformed other firms at the beginning of the pandemic but underperformed during recovery as the Novel Coronavirus spread throughout the world.

Purpose: This study aims to bridge the gaps in the existing literature by studying the links between children's development and the subjective well-being of the caregivers using first-hand data collected in rural China. Design/methodology/approach: Although the broad array of literature has examined the effects of child development on the subjective well-being of caregivers, the relationship between early childhood development and caregiver subjective well-being has not been well-studied using sample families with potential developmental delay in rural China. Also, existing research has relied on maternal reports to evaluate the developmental status of children. The study used data collected from 32 townships in seven nationally designated poverty counties in the Qinling mountainous area in 2016. The authors measure child development using the social-emotional module of the Ages & Stages Questionnaire and Bayley Scales of Infant and Toddler Development–Third Edition. Findings: The authors find that child development indicators are correlated with caregiver subjective well-being. In particular, social-emotional skills are positively associated with life evaluations and positive emotion. However, we do not find any significant correlation between child development and negative emotion or depression, anxiety and stress scores. Originality/value: The value of this study is to report the indicators of child development in rural China and examines the correlation between child development and caregivers' subjective well-being.
