How would economic growth be affected if productivity declined?

If productivity declined, economic growth would likely slow down or stagnate, as lower productivity means that fewer goods and services are produced per unit of labor or capital. This reduction in efficiency can lead to decreased output and income, making it harder for businesses to expand and for the economy to grow. Additionally, lower productivity can result in higher production costs, which may increase prices and reduce overall consumer spending, further hampering economic growth. Ultimately, sustained declines in productivity can lead to lower living standards and economic stagnation.
