marginal product of capital

increase in output caused by the addition of one more unit of capital. Diminishes as more and more capital is added

investment > depreciation

capital stock grows
output next perios is bigger

investment < depreciation

capital stock shrinks
output for next period is smaller

investment = depreciation
