Downward sloping accumulation demand curve
You are watching: Which of the following explains why the aggregate demand curve slopes downward?
The first factor for the downward slope of the aggregate demand also curve is Pigou"s riches effect. Recall that the nominal worth of money is addressed, but the real worth is dependent upon the price level. This is because for a given amount of money, a lower price level offers even more purchasing power per unit of currency. When the price level drops, consumers are wealthier, a condition which induces more consumer spfinishing. Thus, a drop in the price level induces consumers to spfinish more, thereby raising the aggregate demand also.
The second reason for the downward slope of the accumulation demand also curve is Keynes"s interest-rate impact. Recontact that the quantity of money demanded is dependent upon the price level. That is, a high price level means that it takes a relatively big amount of money to make purchases. Therefore, consumers demand also big quantities of currency once the price level is high. When the price level is low, consumers demand also a fairly tiny amount of money bereason it takes a relatively small amount of money to make purchases. Thus, consumers save bigger quantities of currency in the bank. As the amount of currency in financial institutions increases, the supply of loans increases. As the supply of loans rises, the price of loans--that is, the interest rate--decreases. Thus, a low price level induces consumers to save, which in turn drives down the interemainder price. A low interemainder rate rises the demand also for investment as the cost of investment drops via the interest price. Therefore, a drop in the price level decreases the interest price, which boosts the demand for investment and also thereby boosts accumulation demand also.
The 3rd reason for the downward slope of the aggregate demand curve is Mundell-Fleming"s exchange-price impact. Recontact that as the price level drops the interest price additionally tends to loss. When the residential interest rate is low loved one to interest prices available in international countries, residential investors tend to invest in international countries wbelow rerotate on investments is greater. As residential currency flows to international nations, the genuine exchange price decreases because the global supply of dollars increases. A decrease in the genuine exadjust rate has the result of boosting net exports bereason residential products and also solutions are fairly cheaper. Finally, a rise in net exports rises accumulation demand also, as net exports is a component of accumulation demand also. Therefore, as the price level drops, interemainder prices fall, residential investment in foreign countries boosts, the real exchange rate depreciates, net exports boosts, and accumulation demand also boosts.
IS-LM model of aggregate demand
There is one more major model that is beneficial for explaining the nature of the accumulation demand curve. This version is dubbed the IS-LM version after the two curves that are connected in the version. The IS curve describes equilibrium in the industry for goods and solutions where Y = C(Y - T) + I(r) + G and the LM curve defines equilibrium in the money industry wbelow M/P = L(r,Y). The IS-LM model exists in a plane with r, the interemainder rate, on the vertical axis and Y, being both earnings and output, on the horizontal axis. The IS-LM model has actually the exact same horizontal axis as the aggregate demand curve, but a various vertical axis.

The IS curve describes equilibrium in the market for items and services in regards to r and also Y. The IS curve is downward sloping because as the interemainder price drops, investment increases, thus boosting output. The LM curve defines equilibrium in the industry for money. The LM curve is upward sloping bereason greater revenue results in higher demand also for money, thus resulting in better interemainder prices. The intersection of the IS curve via the LM curve mirrors the equilibrium interest price and also price level.
