QUCEH Working Paper Series
Working papers by QUCEH Research Associates, Research Affiliates and Research Students are distributed from this page.

'COVID-19, Race and Redlining'
July 2020
Discussion on the disproportionate impact of COVID-19 on African Americans has been at center stage since the outbreak of the epidemic in the United States. To present day, however, lack of race-disaggregated individual data has prevented a rigorous assessment of the extent of this phenomenon and the reasons why blacks may be particularly vulnerable to the disease. Using individual and georeferenced death data collected daily by the Cook County Medical Examiner, we provide first evidence that race does affect COVID-19 outcomes. The data confirm that in Cook County blacks are over-represented in terms of COVID-19 related deaths since -- as of June 16, 2020--they constitute 35 percent of the dead, so that they are dying at a rate 1.3 times higher that their population share. Furthermore, by combining the spatial distribution of mortality with the 1930s redlining maps for the Chicago area, we obtain a block group level panel dataset of weekly deaths over the period January 1, 2020-June 16, 2020, over which we establish that, after the outbreak of the epidemic, historically lower-graded neighborhoods display a sharper increase in mortality, driven by blacks, while no pre-treatment differences are detected. Thus, we uncover a persistence influence of the racial segregation induced by the discriminatory lending practices of the 1930s, by way of a diminished resilience of the black population to the shock represented by the COVID-19 outbreak. A heterogeneity analysis reveals that the main channels of transmission are socioeconomic status and household composition, whose influence is magnified in combination with a higher black share.

'Bitter Sugar: Slavery and the Black Family'
May 2020
We empirically assess the effect of historical slavery on the African American family structure. Our hypothesis is that female single headship among blacks is more likely to emerge in association not with slavery per se, but with slavery in sugar plantations, since the extreme demographic and social conditions prevailing in the latter have persistently affected family formation patterns. By exploiting the exogenous variation in sugar suitability, we establish the following. In 1850, sugar suitability is indeed associated with extreme demographic outcomes within the slave population. Over the period 1880-1940, higher sugar suitability determines a higher likelihood of single female headship. The effect is driven by blacks and starts fading in 1920 in connection with the Great Migration. OLS estimates are complemented with a matching estimator and a fuzzy RDD. Over a linked sample between 1880 and 1930, we identify an even stronger intergenerational legacy of sugar planting for migrants. By 1990, the effect of sugar is replaced by that of slavery and the black share, consistent with the spread of its influence through migration and intermarriage, and black incarceration emerges as a powerful mediator. By matching slaves’ ethnic origins with ethnographic data we rule out any influence of African cultural traditions.

'Death, Demography and the Denominator: New Influenza-18 Mortality Estimates for Ireland'
May 2020
Using the Irish experience of the Spanish flu, we demonstrate that pandemic mortality statistics are sensitive to the demographic composition of a country. We build a new demographic database for Ireland’s 32 counties with vital statistics on births, ageing, migration and deaths. We then show how age-at-death statistics in 1918 and 1919 should be reinterpreted in light of these data. Our new estimates suggest the very young were most impacted by the flu. New studies of the economic impact of Influenza-18 must better control for demographic factors if they are to yield useful policy-relevant results. Covid-19 mortality statistics must go through a similar procedure so policymakers can better target their public health interventions.

'Monetary Regimes, the Term Structure and Business Cycles in Ireland, 1972-2018'
May 2020
The ability of the term structure (specifically the term spread, or the difference between the long and short ends of the yield curve) to predict economic activity is empirically well-established for the US, but less so for small open economies. The literature emphasizes the role of monetary policy for this predictive ability. Between 1972-2018, Ireland experienced three monetary regimes: first, the Irish Pound was fixed to Sterling (1972-1979); second the Pound floated in a band when Ireland was a member of the EMS (1979-1998); and third, as a member of the euro area (1999-2018). Using dynamic probit models and monthly data, I show that the term spread only had predictive power during the second regime, the only one in which the Central Bank of Ireland had any discretion to set interest rates based on domestic conditions.
