A panel of three experts (Dr. Alpha, Dr. Beta, and Dr. Gamma) is discussing the overall health of the economy. Dr. Alpha argues that the economy is healthy and cites the September 2023 unemployment rate of 3.8% as evidence. Dr. Beta argues that the unemployment rate cannot express the overall health of the economy because it does not distinguish between full-time and part-time employment. Dr. Gamma argues that the unemployment rate cannot express the overall health of the economy because it cannot identify those individuals who are underemployed. 1.
