This study examines the transmission of monetary policy in Brazil's manufacturing sectors from 1996 to 2019. Utilizing detailed sectoral data, we employ a dynamic panel estimation approach to identify the most relevant transmission channels. Our findings highlight the significant influence of labor intensity on the transmission of monetary policy to output levels. By focusing on sector-specific data, this study offers insights into the heterogeneous effects of monetary policy on different industries, contributing to our understanding of the broader economic impacts of Central Bank decisions.
