👋 I'm Danielle, and I'm on the #econjobmarket this year!
Let's start with a student describing her segregated school:
"The school felt temporary. Built like a warehouse with aluminum siding . . . I had a slipshod education"
The twist? The student is white, and her school is private.

My JMP asks a classic question:
Do large, dominant firms foster or hinder innovation?
To study this, I turn to the Great Merger Wave (1895–1904), when >2,600 U.S. firms combined into corporate giants like U.S. Steel and DuPont.

Wars were mostly bad for European economic development. Might be obvious to ordinary people, but it's not considered obvious in economic history. But I think it's obvious ;-)

Good history helps us avoid nostalgia. The great article “Economic History and the Historians” (2020) by Anne McCants reminds me why nostalgia can get us in trouble. Two of her examples are very relevant to today: vaccinations and the popular narrative of some economic “good old days.”

Mergers are followed by large and persistent increases in lobbying activity, both by individual firms and by industry trade associations, suggesting that firms with market power will also attempt to gain political power.

There has been no increase in the economic diversity of elite private and public colleges in the United States over the last century.
However, these colleges have become more racially and geographically diverse.

The more I work on my research, the more I feel that in economics we brush over data construction too quickly. Cool data sources get attention, but the actual work of building and linking datasets is often the “boring” part, glossed over in papers and presentations—if mentioned at all. #EconSky 📉📈
