Variability in the Grades Teachers Give
We identify systematic differences in ninth-grade teachers’ effects on students’ course grades in their class (ninth-grade grade value-add), their persistent effects on students’ grades in the same subject of the next grade (tenth-grade grade value-add, representing effectiveness at academic preparation), and mismatch between the grades they give and students’ subsequent performance (representing inaccurate measurement). Persistent effects and mi…
Ozone depletion, ultraviolet radiation, climate change and prospects for a sustainable future
The South, Slavery, and Competition in Early US House Elections
In this study of the early US Congress (First through Nineteenth: 1789–1827), we assess the impact of slavery on the electoral competitiveness of House elections. Slavery and other forms of labor repressive agriculture have long been known to undermine democracy. Using district-level measures of electoral competitiveness and slavery, we find that a higher percentage of slaves in a district negatively impacts competition, even when we limit our mo…
Attempts to Probe the Ozone Layer and the Ultraviolet-B Levels of the Past
To get a proper perspective on the current status of atmospheric ozone, which protects the biosphere from ultraviolet-B (UV-B; 280-315 nm) radiation, it would be of value to know how ozone and UV-B radiation have varied in the past. The record of worldwide ozone monitoring goes back only a few decades, and the record of reliable UV-B measurements is even shorter. Here we review indirect methods to assess their status further back in time. These i…
