  • Land Quality (paper, slides)

  • We develop a new measure of land quality by estimating weights in a Poisson regression of grid-cell population on geographic characteristics and country fixed effects. Aggregating to countries, we construct average land quality (ALQ) and quality-adjusted population density (QAPD). We show: First, current income per capita is positively correlated with ALQ. Second, while income today is unrelated to conventional population density, it is strongly negatively related to QAPD. Third, this negative relationship was not present in 1820 and emerged because today’s lower income countries have experienced faster subsequent population growth. Fourth, countries with higher average land quality began sustained modern economic growth earlier, and this earlier takeoff largely explains the modern income-ALQ relationship. We posit a framework in which land quality induced denser populations in Malthusian equilibrium and, via agglomeration, earlier takeoffs. Less dense countries experienced larger population multipliers during their later demographic transitions due to imported health technologies.

3) 4:10pm - 4:50pm (GN Hall 301)

  • Intergenerational Impact of Early Life Exposure to Trauma: Parental Exposure to the Korean War and Risk Aversion (paper, slides)

  • This paper investigates the intergenerational effects of early life exposure to the Korean War on risk aversion. We find that the intergenerational transmission of risk attitude is negative for war victims, using a structural estimation method. Disassortative matching and differential fertility are ruled out for potential mechanisms as the treatment group displays assortative matching and has a similar number of siblings. The mother-son dyad shows the most significant negative intergenerational transfer, suggesting parent-child attachment as the key mechanism. Behavioral evidence supports the results by showing that the children are not less likely to be self-employed.

  • From Samurai to Skyscrapers: How Transaction Costs Shape Tokyo (paper, slides)

  • Whether transaction costs to assemble or split land can persistently hinder urban land use remains unknown. Constructing a 100 m*100 m-cell-level dataset of central Tokyo from the 19th-century pre-modern era to the 21st-century skyscraper era, we study how initial lot fragmentation has affected urban development. We exploit a plausibly exogenous supply shock of large lots in 1868, the release of local lords’ estates (daimyo yashiki) scattered throughout central Tokyo. Using ordinary least squares and a regression discontinuity design, we find that cells previously used as local lords’ estates have larger lots today, implying that lot size persists through transaction costs. Such cells today see more tall buildings, higher land prices, and higher labor productivity of firms. We also find these effects only in the core area, suggesting higher transaction costs in this area. Finally, the effect of lot size on land prices became positive only after the rise of skyscrapers. This implies that optimal lot size became larger and assembly friction became more salient in the skyscraper age. Overall, transaction costs to change lot size persistently hinder economic activities; in particular, this dominatesthe potentially large benefits of assembly for skyscraper development in growing urban cores.

  • Does More Democracy Encourage Individualism?: Evidence from Women's Suffrage in the US (slides)

  • This study explores the relationship between two key factors in modern society: democracy and individualism. We suggest a hypothesis that the extension of suffrage stimulates a sense of autonomy and independence, which contributes to the rise of individualism. Evidence from the history of women’s suffrage in the US supports this proposition. Exploiting temporal variation in suffrage laws across states, border-county-pair analyses show that the passage of women’s suffrage led to an increase in individualism, which is measured by the prevalence of uncommon names. Moreover, falsification tests suggest that the relationship between women’s suffrage and individualism is rooted not in women’s rights, but in voting rights.
