The Intergenerational Mortality Tradeoff of COVID-19 Lockdown Policies

In lower-income countries, the economic contractions that accompany lockdowns to contain the spread of COVID-19 can increase child mortality, counteracting the mortality reductions achieved by the lockdown. To formalize and quantify this effect, this paper builds a macro-susceptible-infected-recovered model that features heterogeneous agents and a country-group-specific relationship between economic downturns and child mortality. The model is calibrated to data for 85 countries across all income levels. The findings show that in low-income countries, a lockdown can potentially lead to 1.76 children’s lives lost due to the economic contraction per COVID-19 fatality averted. The figure stands at 0.59 and 0.06 in lower-middle-income and upper-middle-income countries, respectively. As a result, in some countries, lockdowns can produce net increases in mortality. The optimal lockdowns are shorter and milder in poorer countries than in rich ones and never produce a net mortality increase.

The Distribution of Effort: Physical Activity, Gender Roles, and Bargaining Power in an Agrarian Setting

The disutility of work, often summarily described as effort, is a primal component of economic models of worker and consumer behavior. However, empirical applications that measure effort, especially those that assess the distribution of effort across known populations, are historically scarce. This paper explores intra-household differences in physical activity in a rural agrarian setting. Physical activity is captured via wearable accelerometers that provide a proxy for physical effort expended per unit of time. In the study setting of agricultural households in Malawi, men devote significantly more time to sedentary activities than women (38 minutes per day), but also spend more time on moderate-to-vigorous activities (16 minutes). Using standardized energy expenditure as a summary measure for physical effort, women exert marginally higher levels of physical effort than men. However, gender differences in effort among married partners are strongly associated with intra-household differences in bargaining power, with significantly larger husband-wife effort gaps alongside larger differences in age and individual land ownership as well as whether the couple lives as part of a polygamous union. Physical activity -- a proxy for physical effort, an understudied dimension of wellbeing -- exhibits an unequal distribution across gender in this population.
