Labor Market Dynamics in the U.S. Food Sector
构建联立方程模型，分析美国食品行业劳动力市场（工资、就业、劳动生产率）与食品价格的关系，发现工资决定在价格传导中起核心作用，能源价格冲击显著影响食品价格，而外生商品价格冲击会降低劳动生产率。
Abstract A simultaneous equation model is estimated to explain labor market phenomena (including wages, employment, and labor productivity) and food prices at manufacturing and retail levels of the U.S. food industry. Dynamic simulation results show that endogenizing input costs in a fully specified markup‐pricing model leads to a complex long‐run pattern of food price determination. Wage determination is found to play a central role linking general price levels to food sector prices and labor market behavior. Energy price changes are shown to significantly affect food prices. Food sector labor productivity is found to decline in response to exogenous commodity price shocks.
