Imported capital goods and the income adjustment process in small open economies

Abstract

The principle of effective demand states that given endogenous expenditure patterns, the level of exogenous expenditure determines the level of employment. If investment represents the sole form of exogenous expenditure, employment adjusts to the level of investment. If exogenous expenditure changes, equilibrium is restored via the equilibrating variable, employment. If employment is linked in a unique way to income, we have what is referred to as the income adjustment process. The income adjustment process is investigated in a closed and a small open economy (SOE) which imports consumption and capital goods. If a SOE imports its capital goods, the causal link between investment and employment is weakened. When capital goods are imported, investment adjusts to the balance of payments and animal spirits are constrained. Certain South African data are analysed within the framework of the income adjustment process.
