Four key markets and the circular flow of income

The circular-flow diagram is a visual model of the economy. The circular flow of income is coordinated by four key markets.

The resource market coordinates businesses demanding resources and households supplying them in exchange for income.The loanable funds market brings the net saving of households plus the net inflow of foreign capital into balance with the borrowing by businesses and governments.The foreign exchange market brings the purchases (imports) from foreigners into balance with sales (exports plus net inflow of capital) to them.The goods and services market coordinates the demand (consumption, investment, government purchases, and net exports) with the supply of domestically produced goods and services (real GDP).

\f3. Why the aggregate demand curve slopes downward The following graph shows the aggregate demand (AD) curve in a hypothetical economy. At point A, the price level is 140, and the quantity of output demanded is $300 billion. Moving down along the aggregate demand curve from point A to point B, the price level falls to 120, and the quantity of output demanded rises to $500 billion.

The number of domestic products purchased by foreigners (exports) will therefore , and the number of foreign products purchased by domestic consumers and firms (imports) will . Net exports will therefore4. Determinants of aggregate demand The following graph shows a decrease in aggregate demand (AD) in a hypothetical country. Specifically, aggregate demand shifts to the left from AD, to AD2, causing the quantity of output demanded to fall at all price levels. For example, at a price level of 140, output is now $200 billion, where previously it was $300 billion.
