Can offshoring increase quality? A dynamic model

open access: yes, 2021
We propose a dynamic model to study the problem of relocating production to a foreign country, where production costs are lower. The idea is to investigate the impact of offshoring on the quality of the manufactured goods in a simple dynamic model, which
