A MethodFor Separating Iincome & Substitution Effects Of Exchange Rate Changes On Aggregate Demand

Regression estimates of exchange rate total effects on aggregate demand are broken into separate income and substitution effects. Total effects estimates can seem contrary to theory. Separating them into their two components shows this is not the case. The separation method also provides a simple test to determine if imports are normal or inferior goods. The paper finds consumer imports are normal goods, but investment imports are inferior goods. The paper shows that if import total effects exceed domestic total effects, imports are a normal good. If smaller, they are inferior goods.
