Thomas Piketty's Capital in the Twenty-First Century. The authors examine critiques of Piketty's work, focusing on his argument that the rate of return on capital (r) exceeding economic growth (g) leads to increasing inequality. They explore various economic models and historical data, considering factors like technological change, globalization, and the role of institutions in shaping inequality. The text also discusses the political and social contexts surrounding Piketty's book, including its reception and implications for policy. Finally, it considers the limitations of Piketty's analysis, particularly concerning data limitations and the need for a more nuanced understanding of factors affecting inequality.
