I analyze factory worker households in the early 1920s in Osaka to examine idiosyncratic income shocks and consumption. Using the household-level monthly panel dataset, I find that while households could not fully cope with idiosyncratic income shocks at that time, they mitigated fluctuations in indispensable consumption during economic hardship. In terms of risk-coping mechanisms, I find suggestive evidence that savings institutions helped mitigate vulnerabilities and that both using borrowing institutions and adjusting labor supply served as risk-coping strategies among households with less savings.

AbstractThis study examines a catastrophic earthquake in 1923 to analyse the long‐term effects of a natural disaster on children's health. The findings show that foetal exposure to Japan's Great Kantō Earthquake had stunting effects on girls in the devastated area. Disaster relief spending helped remediate stunting among boys by late primary school age, whereas it did not ameliorate girls' stunting, which suggests a prenatal selection mechanism and compensating investment after birth. While maternal mental stress due to the fear of vibrations and anticipation of future aftershocks played a role in the adverse health effects, maternal nutritional stress via physical disruption also enhanced those effects.

AbstractJapan's Great Kantō Earthquake of 1 September 1923 devastated the area around Tokyo and the country's main port of Yokohama. This article uses the earthquake as a case study to inform our understanding of the economics of disasters and the history of market integration. It seeks to test two main assumptions: first, that shifting demand and supply curves consequent on a disaster will have some impact on prices; and second, that any local changes in the disaster region are likely to be diffused across a wider geographical area. We make use of a unique monthly wholesale price dataset for a number of cities across Japan, and our analysis suggests three main findings: that price changes in the affected areas immediately following the disaster were in most cases reflected in price changes in Japan's provincial cities; that cities further away from the devastation witnessed smaller price changes than those nearer to the affected area; and that the observed pattern of price changes reflects the regional heterogeneity identified by scholars who have worked on market integration in Japan.

This paper assesses how the disease environment, proxied by infant mortality rates, influenced children's growth in interwar Japan. We use data drawn from government records from 1929 to 1939 which report the mean heights of boys and girls in school at each age (6-18) for each of Japan's 47 prefectures. We focus on two key questions: 1) how important was the disease environment in infancy in shaping the growth pattern of children? and 2) were shocks to child health more salient in the first thousand days of life, often held as a critical window to prevent stunting, or at later ages? We quantify the characteristics of growth pattern of birth cohorts using the SITAR growth model and then relate the predicted SITAR parameters to infant mortality in the year of birth. In addition, we test for instantaneous effects of morbidity, proxied by infant mortality, on growth at ages 6-11. We find that infant mortality in early life did not have a strong influence on the growth pattern of children, but there were statistically significant and economically meaningful instantaneous effects of infant mortality on child height at ages 6-11 for both boys and girls. This suggests that interventions outside of the thousand-day critical window can be effective and that the secular increase in height in interwar Japan was more strongly influenced by cumulative responses to the health environment across child development rather than simply improvements in early life health.

This article employs a household survey of low‐income working‐class households conducted in Tokyo in 1930 to investigate nutritional attainment levels and the relationship between calorie intake and morbidity. We find that the daily calorie intake was 2,118 kcal per adult male equivalent, high enough to satisfy the energy requirements for moderate physical activity. Richer households purchased more expensive calories mainly by substituting meat and vegetables for rice. We find negative associations between morbidity and income and crowding, but no significant associations for nutrition, tentatively suggesting that income and crowding were more important for morbidity in 1930 Tokyo than nutrition.
