Self-learning at the right level, Covid-19, school closure, and non-cognitive abilities
The COVID-19 pandemic and associated school closures exacerbated the global learning crisis, especially for children in developing countries. Teaching at the right level is gaining greater importance in the policy arena as a means to recover learning loss. This study forms part of an emerging body of work to examine the long-term effects of experimental educational interventions. In particular, we investigate the long-term effects of Kumon’s “sel…
Covid-19 containment policies, digitalization and sustainable development goals
The impact of digital platforms on the implementation of the United Nations’ (UN) Sustainable Development Goals (SDGs), especially the business sustainability of micro, small and medium-sized enterprises (MSMEs), under different containment policies during and after the COVID-19 pandemic has not yet been studied in detail. Using detailed administrative data from Alibaba Group’s online on-demand food delivery platform, we found that the digital pl…
Fighting the Learning Crisis in Developing Countries
This paper investigates the effectiveness of a globally popular method of self-learning at the right level in improving learning outcomes|the cognitive and non-cognitive abilities of disadvantaged pupils|in a developing country, Bangladesh. Using a randomized control trial design, we find substantial improvements in cognitive abilities measured by mathematics test scores and catch-up effects on aspects of non-cognitive abilities or personality tr…
Haste Makes No Waste
This study investigates the effects of speed competition in classrooms on young pupils' learning outcomes. To examine how faster peers' speed affects slower pupils' speed and learning, we employ students' daily progress data in a self‐learning programme at BRAC primary schools in Bangladesh. The programme's unique setting allows us to address the reflection problem reasonably well. While speed competition could generate negative consequences, our…
Association between housing damage, present bias and delayed-onset post-traumatic stress symptoms among older adults 9 years after a natural disaster
BACKGROUND: Previous studies suggest that experience of natural disasters may heighten present bias. Research also suggests that impaired self-control (in particular, heightened present bias) could be linked to delayed-onset post-traumatic stress symptoms (PTSS) among survivors of natural disasters. We examined a hypothesis that the association between disaster experiences and delayed-onset PTSS is mediated through present bias among older surviv…

“Wisdom of the Elders” or “Loss of Experience” as a Mechanism to Explain the Decline in Traditional Ecological Knowledge
Previous studies have reported that older people are more knowledgeable about nature than the younger generation. The relationship between people’s age and level of knowledge can be explained via two mechanisms: knowledge increases with age (wisdom of the elders), and opportunities to acquire knowledge decrease with successive generations (loss of experience). In this study, we examined the association between age and knowledge regarding the use …
Short and Long Recall Errors in Retrospective Household Surveys
While recall errors in retrospective data from household surveys may generate estimation biases, the nature and the relative magnitude of the errors are still largely unknown, especially in the context of developing countries. To bridge this gap in the existing studies, we conduct a resurvey of respondents of the Vietnam Household Living Standards Survey (VHLS) 2006. The combined data set allows us to investigate a variety of short-term and long-…
Disasters, Insurance, and Preferences
Recently both developed and developing countries have experienced numerous serious disasters that can be subdivided into four major groups: natural, technological, economic crises, and violence-related disasters. These negatively affect not only the livelihoods of the survivors but also their preferences for risks and time delays. In preparation for or in the aftermath of a disaster, various indispensable market and nonmarket mechanisms are avail…

A newly discovered galagid fossil from Nakali, an early Late Miocene locality of East Africa
The latest occurrence of the nyanzapithecines from the early Late Miocene Nakali Formation in Kenya, East Africa
The African primate fossil record is very poor between the mid-Middle and mid-Late Miocene. Nakali (~10–9.8 Ma) is one of the rare African localities that have yielded primate fossils from this period, including a new genus of great ape, Nakalipithecus nakayamai, and another large-bodied hominoid species. The Nakali primate fauna also includes small-bodied ‘apes’ and Old World monkeys (mostly colobines). In this article, we describe a new specime…
Tweeting celebrity suicides
A substantial amount of evidence indicates that news coverage of suicide deaths by celebrities is followed by an increase in suicide rates, suggesting a copycat behavior. However, the underlying process by which celebrity status and media coverage leads to increases in subsequent suicides is still unclear. This study collected over 1 million individual messages ("tweets") posted on Twitter that were related to 26 prominent figures in Japan who di…
A second hominoid species in the early Late Miocene fauna of Nakali (Kenya)
Nakali is an early Late Miocene fossil locality in north-central Kenya, where the Kenya–Japan Joint Expedition team has carried out fieldwork since 2002. Previously, a large hominoid Nakalipithecus nakayamai was reported from site NA39 of this locality. In addition to Nakalipithecus, the hominoid material collected from Nakali includes an isolated P3, which shows a considerably different morphology from the P3 assigned to Nakalipithecus, suggesti…

Resilience and Recovery in Asian Disasters
This book establishes a new, holistic framework for disaster recovery and mitigation, providing a multidisciplinary perspective on the field of risk management strategies and societal and communal resilience. Going beyond narrow approaches that are all too prevalent in the field, this work builds on an optimum combination of community-level networks, private market mechanisms, and state-based assistance strategies. Its chapters describe best prac…

How Access to Irrigation Influences Poverty and Livelihoods
This study combines a livelihoods approach with a regression approach to quantify the effectiveness of irrigation infrastructure investment on improving people's livelihood strategies. Using a unique dataset based on households in southern Sri Lanka, and a natural experimental setting, we estimate from a two-stage income regression model to show that irrigation access has a positive effect on income through livelihood choices. We also show throug…

Does Community Management Help Keep Children in Schools? Evidence Using Panel Data from El Salvador's Educo Program
This article investigates how community management of schools can affect educational outcomes as measured by retention rates. In our model, parents make decisions about whether or not their children should remain in school, and they monitor the performance of the teachers. We analyze a unique data set from El Salvador, which expanded the role of communities in school management through its Educación con Participación de la Comunidad (EDUCO) progr…

Earliest colobine skeletons from Nakali, Kenya
Old World monkeys represent one of the most successful adaptive radiations of modern primates, but a sparse fossil record has limited our knowledge about the early evolution of this clade. We report the discovery of two partial skeletons of an early colobine monkey ( Microcolobus ) from the Nakali Formation (9.8–9.9 Ma) in Kenya that share postcranial synapomorphies with extant colobines in relation to arboreality such as mediolaterally wide dist…

The Changing Determinants of Schooling Investments
This paper aims to explore the changing determinants of child progress through school over the last two decades using unique long-term household-panel data from four villages in the Philippines. In a regime of low income in the late 1980s, income from farming is the most important source of funds to finance child schooling. As households shift away from farm to non-farm activities and their children pursue higher education, non-farm income and re…
Did Public Transfers Crowd Out Private Transfers in Korea During the Financial Crisis
How effective are public transfers in protecting households facing financial crisis-induced negative shocks? Existing studies have not yet carefully considered the inter-relationship between public transfers and the existing private transfer network. In the context of the financial crisis in Korea, this paper investigates the possible crowding-out effect of public transfers on private transfers by explicitly considering the endogenous responses o…

Transformation of the Rural Economy in the Philippines, 1988–2006
This research explores the changing structure of the rural economy in the Philippines from 1988 to 2006. We found that the expansion and upgrade of infrastructure such as electricity and roads and investment in secondary and tertiary education are important factors that induced the economic transformation of the rural economy. The importance of higher education as an entry requirement to the nonfarm labor market has declined over time, indicating…

Why is Absenteeism Low among Public Health Workers in Lao PDR
Absenteeism among public health workers is common in developing countries. Absence rates among public health workers are above 25 per cent in the five developing countries that Chaudhury et al. (N.
