Economic Definition of disinvestment. Defined.
Offline Version: PDF
Term disinvestment Definition: A drop in the total quantity of capital in the economy because the depreciation of existing capital is greater than investment in new capital. In other words, the capital we have is wearing out faster than we're replacing it with new stuff. This isn't good. At best, it limits economic growth and might even cause the economy's pie to shrink if increases in other resources don't kick in.
