Reinhart and Rogoff (Carmen Reinhart and Kenneth Rogoff)

Reinhart and Rogoff are economists known for their research on government debt and economic crises. They analyzed historical data to show that when a country's public debt exceeds about 90% of its GDP, economic growth tends to slow significantly, and the risk of fiscal crises increases. Their work highlighted the potential dangers of high debt levels for national economies. However, some of their findings became controversial when errors were later identified, leading to debates about the precise relationship between debt and growth. Overall, their research contributed to discussions on fiscal policy and debt sustainability.
