Abstract

Rising input costs can make it difficult for businesses to remain competitive; however they can also force firms to innovate. This study investigates how cost shocks affect firm productivity and innovation. We build a model that considers that some firms are better at innovating than others. We found that when costs go up under certain conditions, it can increasingly incentivize capable firms to innovate and become more productive, but the opposite is true for less competent firms. Using Chinese firm-level data, we empirically test the validity of our model’s prediction and find strong support. Further examination underscores the moderating role of R&D in facilitating productivity growth when firms face oil price shocks.
