Critical Evaluation
Value of the Information & Strength of the Argument
The value of the information is high, as it presents new historical evidence that challenges conventional narratives about the evolution of income inequality. The argumentation is solid, with the speaker carefully explaining the data sources, methodology, and limitations. The use of a unique 1936 tax dataset provides a novel perspective, and the comparison with census data adds robustness. The speaker also engages with existing literature, such as work by Atkinson, Piketty, and others, situating the findings within broader debates. However, the presentation is preliminary, and some claims are not fully developed, particularly regarding the mechanisms driving the observed patterns.
Scientific Rigor, Source Quality, Title Accuracy
The presentation demonstrates scientific rigor through transparent discussion of data limitations and methodological choices. The sources cited include well-known scholars and datasets, such as the Statistics of Income and census data. The title accurately reflects the content, focusing on new evidence from the 1936 tax project. The speaker also acknowledges potential issues with data comparability and the need for further research. Overall, the sources are appropriate and the title is well-aligned with the content.

Concurring Sources
- Piketty and Saez's work on top incomes — Their research on top income shares provides a foundation for understanding income inequality trends.
Dissenting Sources
- DINA data — The speaker notes that DINA data may break the association between capital and labour income due to imputation methods, which could be seen as discordant with the findings.
Contribution & Novelties
The presentation offers a novel historical perspective on the composition of top incomes, using a unique 1936 tax dataset that has not been fully exploited. It challenges the assumption that the overlap between top labour and capital incomes has been steadily increasing since the mid-20th century, showing that it was already high in 1936. This suggests that the shift from classical capitalism to welfare capitalism involved more complex dynamics than previously thought. The speaker also highlights the importance of business organization changes, such as the shift from corporations to partnerships, in explaining these patterns.
