美国经济专题深度研究：美国就业情况到底如何？

Group 1: Employment Data Analysis - The U.S. non-farm payroll data may be overestimated, with a significant downward revision of 344,000 jobs in Q1 2024 due to the Birth-Death Model's lagging indicators[10] - The CES (Current Employment Statistics) data may have overestimated non-farm employment by approximately 635,000 jobs from January to August 2025, influenced by an increase in multiple jobholders and a decrease in unpaid leave[15] - The CES survey response rate has declined from 60% in January 2020 to 42.6% in March 2025, indicating a potential increase in statistical errors[13] Group 2: Labor Market Dynamics - Since March 2025, the U.S. has seen a net loss of 1.48 million immigrant workers, while native labor supply has increased by 1.861 million[23] - The "native substitution" effect is unlikely to be sustainable due to the aging population and the inability of native workers to fill the gaps left by departing immigrants[33] - The labor market is experiencing a trend of declining hiring rates and slightly increasing layoff rates, with a pessimistic outlook on job switching due to low wage growth[20] Group 3: Sector-Specific Insights - The cyclical industries, such as leisure and hospitality, construction, and manufacturing, are showing significant employment slowdowns, with the construction sector particularly affected by a cooling housing market[40] - The leisure and hospitality sector has a high turnover rate, with a youth participation rate of 34.48% and a part-time rate of 44.1%, leading to a unique "high demand, high supply" balance[47] - Non-cyclical sectors like education and healthcare are facing downward risks, with the healthcare sector experiencing job losses of at least 70,000 in the past year due to policy changes and layoffs[29]
