What is the effect of the decline of GM's productivity on its cost efficiency production and profit?

The decline in GM's productivity typically leads to higher production costs, as less efficient operations require more resources and time to produce the same output. This reduction in cost efficiency can squeeze profit margins, making it harder for the company to remain competitive in the automotive market. Additionally, increased costs may force GM to either raise prices or absorb losses, both of which can negatively impact overall profitability. Ultimately, sustained productivity declines could jeopardize GM's financial health and market position.
