Efficiency and productivity growth in US food manufacturing industries: Exporters, ownership changes, and firm characteristics

This study employs a stochastic production frontier framework to measure productivity growth among exporters, non-exporters, and firms experiencing ownership changes through mergers and acquisitions in US food manufacturing. Analyzing a panel data set that integrates Economic Censuses and transaction-level exports, the results reveal the coexistence of more productive exporters, driven by technical efficiency, alongside less productive non-exporters. Exporters in arm's length transactions show productivity growth driven by technical efficiency change, while those in related party transactions benefit mainly from technological change. Firms undergoing ownership changes exhibit positive productivity growth with a greater contribution from technical efficiency compared to those without such changes.
