This study did five surveys between April 2020 and March 2021 to look at how lifestyle changes during the pandemic affected well-being. These surveys covered all of Japan and were done both before and after the state of emergency was lifted. Applying the fixed-effects method to the panel data acquired in this manner, the analysis focused on subjective well-being and behavior during the COVID-19 pandemic. The results showed that teleworking during the pandemic may have increased life satisfaction, especially among young people. Although self-restraint behavior reduced well-being among young people, it tended to increase well-being among elderly individuals. On the other hand, self-restraint behavior by partners was found to lead to a decline in well-being among elderly individuals. In addition, it was observed that both the declaration of a state of emergency and the infection status had minimal impact on life satisfaction and happiness across all generational groups. Thus, the results show that lifestyle changes during the pandemic did not necessarily harm well-being, suggesting that the positive or negative impacts of factors differ from generation to generation.

Background: Seasonality is an important aspect of food security for subsistence households in developing countries. Among the multidimensional aspects of food security, this paper focuses on how unexpected negative harvest shocks would affect the seasonal food consumption of households. This is particularly important because, with the increasing threat of climate change, the frequency of extreme weather events such as droughts and floods is expected to increase; this would adversely affect crop yields. Methods: Given seasonal price changes of staple foods, some households buy them when prices are low and store them for the hunger season (not buy high (NBH) households), while others run out of staple foods before the next harvest and therefore buy them when prices are high (buy high (BH) households). Using three years of weekly household panel data for the Choma and Sinazongwe Districts of the southern province of Zambia, we assess the ability of seasonal consumption smoothing separately for NBH and BH households. Results: NBH households successfully smooth their consumption over the 12 months of the crop year. In contrast, BH households, especially for households with few assets, reduce total consumption in response to harvest shocks, just after the harvest and during the “hunger season” just before the next harvest. However, in spite of this, the consumption of staple foods is generally insensitive to harvest shocks. Instead, they reduce consumption only of non-staple food items, such as vegetables and meats. Conclusions: Seasonal food insecurity is exacerbated by negative harvest shocks. We emphasize the significance of policies aimed at increasing public awareness of healthier food choices, empowering households to avoid purchasing maize at high prices, and reducing seasonal price disparities.

Whether perceived importance can be used as a weighting factor for the aggregation of domain satisfaction is an important issue in the literature on subjective well-being (SWB) measures with multidimensional domains. This paper extends the weighting approach proposed by Benjamin et al. (Am Econ Rev 104:2698–2735, 2014) and uses it to weight domain satisfaction. The weights estimated by this approach can be interpreted as marginal utility, and the weighted average of the domain satisfaction of each individual can be interpreted as the individual’s utility. Using a data set collected from a 2015 survey that we conducted with residents of all Japanese prefectures, we show that this weighted average improves the goodness of fit for overall SWB measures compared with the unweighted averages of domain satisfaction. This finding supports incorporating perceived importance measures into SWB measures. Moreover, we show that, although there are differences in perceived importance among some domains that are less relevant to specific sub-populations, such as work for people above 65 years or relations with family for those who live alone, the relative importance of most domains is similar across the different categories of gender, household income, age, and household composition. Allowing for heterogeneity in the importance weights across these demographic groups provides only negligible improvements to the validity of the domain importance. The approach suggested in this paper can be considered a resident-oriented approach in the sense that the weights are derived from the perceived importance of residents themselves and are thus expected to contribute to resident-oriented policymaking.

This study conducted randomized controlled trials to evaluate the effectiveness of an environmental education class and the impacts of nudges and boosts implemented in this program on high school students' basic knowledge, attitudes, and behaviors regarding environmental issues in Japan. This environmental education class consisted of a lecture on reducing the use of plastic products for energy conservation in daily life, a board game for learning how to reduce plastic waste, and a worksheet for reflection. Four types of worksheets were randomly distributed: nudges, in which students were asked to set a goal regarding their level of effort in not throwing away plastic products such as plastic bags, wet wipes, and plastic bottles; boosts, in which participants were asked to write an essay to help increase their empathy for the parties impacted by environmental issues; both nudges and boosts; and none (neither nudges nor boosts). After environmental education, an end-line survey was conducted to evaluate the effectiveness of this class. This study found that the environmental education class significantly improved students' basic environmental knowledge and promoted their concerns about plastic waste. Although there was no evidence that nudges and boosts amplify the effects of the environmental education class on the students' knowledge, nudges were successful in making them more concerned about plastic waste. The results showed that students who received nudges or boosts were more likely to refuse free wet wipes offered at convenience stores but were not more likely to refuse plastic bottles. These results also indicated that interventions through environmental education can change students' pro-environmental behaviors only if the cost of behavioral change is low. The environmental education class not only increased students’ environmental knowledge and attitudes, but the use of worksheets in administering nudges and boosts ensured the effectiveness of environmental education.
