This paper considers a modification of the standard Susceptible-Infected-Recovered (SIR) model of epidemic that allows for different degrees of compulsory as well as voluntary social distancing. It is shown that the fraction of population that self-isolates varies with the perceived probability...

When other measures for economic welfare are scarce or unreliable, the body mass index (BMI) is a biological measure that reflects current net nutrition. This study uses a difference-in-decompositions framework to analyze how women's BMIs varied with the advent of early 20th century social...

A population’s weight conditioned on height reflects its current net nutrition and demonstrates health variation during economic development. This study builds on the use of weight as a measure for current net nutrition and uses a difference-in-decompositions technique to illustrate how black...

Communities urbanize when the net benefits to urbanization exceed rural areas. Body mass, height, and weight are biological welfare measures that reflect the net difference between calories consumed and calories required for work and to withstand the physical environment. Across the United...

When other measures for economic welfare are scarce or unreliable, the use of biological measures are now standard in economics. This study uses late 19th and early 20th century BMI, statures, and weight to assess how net nutrition accumulated to women and men during US economic development....

Peer and cohort effects are important in health economics, and obesity may be related to social relationships, where obese individuals interact with other obese individuals. There were significant 19th century cohort effects, where BMIs were related to the cohort that an individual belonged....

A population’s average stature reflects cumulative net nutrition and changing long-run economic conditions facing women’s economic opportunity, inequality, and net nutrition during development. This study uses stature as a measure for cumulative net nutrition to show how female and male...

When other measures for material conditions are scarce or unreliable, the use of height is now common to evaluate economic conditions during economic development. However, throughout US economic development, height data by gender have been slow to emerge. Throughout the late 19th and early 20th...

In an RDD study of the incumbency effect, observations somewhat away from the threshold separating winners and losers in an election are necessarily employed. We consider how incorporating the vote volatility of elections into a preferred index of electoral competitiveness or closeness, in...

This paper provides estimates of persistence in historical UK data on life expectancy applying fractional integration methods to both an annual series from 1842 to 2019 and a 5-year average from 1543 to 2019. The results indicate that the former exhibits an upward trend and is persistent but...
