This study investigates pro-social and pro-environmental preferences through a survey experiment that examines behavioral shifts from single-use medical masks to reusable fabric masks among healthy individuals. Drawing on goal-framing theory, we evaluate the impact of the WHO’s recommendation alongside two additional informational interventions encouraging the use of fabric masks over medical-grade alternatives. Using an add-on experimental design, participants were randomly assigned to one of three treatment groups, with baseline responses serving as a reference group.

While numerous majority-controlled governments globally have enacted hostile policies targeting minority groups, the long-term consequences of these policies remain insufficiently explored. By exploiting policy changes directed at the Chinese ethnic minority in South Vietnam between 1956 and 1963, this paper investigates the long-lasting effects of in utero exposure to hostile policies on multigenerational outcomes and social mobility.

Exploiting a policy reform mandating participation in a 300-h language training course in Norway, I investigate the multigenerational health effects of a comprehensive language training program. I document the significant positive impacts of the program, not only on the long-term integration of refugees into the healthcare system but also on the health of the next generation. The program improves the cumulative use of primary care services for 12 years after arrival by 44%.

Abandoned, Lost, or Otherwise Discarded Fishing Gear (ALDFG) is a global challenge, that adversely impacts both marine ecosystems and the livelihood of fishers. This study explores the fishers’ perceptions and concerns regarding ALDFG consequences, and investigates how these concerns shape their willingness to participate in retrieval efforts. Data were collected through a survey of 525 fishers in Khanh Hoa province, Vietnam.

PurposeThe study investigates determinants of willingness to pay (WTP) for laser land leveling (LLL) technology, its demand heterogeneity across individual farmers and plot characteristics and the technology's empirical impact on paddy productivity.Design/methodology/approachThe study applies the Becker-DeGroote, Marschak style to elicit the WTP for LLL technology and the Cragg model to examine the determinants of the WTP to capture both the demand decision and affordability.

The land of what is today Vietnam witnessed the emergence of three early kingdoms during the third century BCE, all decentralized tributary networks of distinct polities. After resisting the colonization of historical China throughout the first millennium, historical Vietnam started to build a unified nation in the Red River Delta following the Sinic model of political centralization and cultural standardization, while the other two kingdoms continued with their decentralized networks.
