The Nevins half of the EHA dissertation session considers the best dissertations in North American economic history completed in the previous 12 months. It is my pleasure and honor to be the convener. I received eight dissertations to consider for the Nevins panel. It was difficult to narrow it down to just three panelists.Before I comment on each of the three dissertations, let me start with my guidelines in deciding who would be the panelists. I was looking for a dissertation and not simply a job market paper. There should be more than one paper, preferably at least three, and the papers should be cohesive, not just "three essays in economic history." I wanted there to be compelling, interesting questions that I should care about that make me think about the world differently.I wanted it to be economic history. Economic history is economics and historytrying to understand historical events through the lens of economics. The analysis should recognize the importance of institutional knowledge and historical context.I wanted to see data work that was far more than simply downloading data. The individual should have had gotten their hands dirty finding some data that they used and demonstrate in their writing that they recognize the context and limitations of their data, but also the beauty of their data.And perhaps reflecting my Berkeley bias, I want there to be applications of the economic history to some sort of contemporary policy questions. While there is fun in history for history's sake, at the end of the day, we are still trying to contribute to a broader conversation about economic policy and making the world a better place.With that said, let me turn to the dissertations themselves. The other morning, I was getting ready for my weekly meeting with two sets of undergrad research assistants, both of whom are working on projects related to improving representation of women and students of color in the economics major. As I dressed, I heard the news about the COVID-19 death of another conservative radio talk show host, coming on the heels of his exhorting his listeners to avoid the vaccine. And as I sat down to eat breakfast, I opened up the New York Times to a full-page ad in favor of statehood for Puerto Rico. Those are the three dissertations on this year's Nevins panel. Let me take them in reverse order.
