Exchange rates are determined in the foreign exchange market, but what causes those exchange rates to change? In this video, learn about why the supply or demand for a currency might change.

In this video we illustrate and explain the differences between a change in the quantity demanded for a good (which causes a movement along a demand curve) and the change in a good's demand (which causes the entire demand curve to shift).

A demand shifter is a change that shifts the demand curve for a product. One of the demand shifters is buyers' expectations. If a buyer expects the price of a good to go down in the future, they hold off buying it today, so the demand for that good today decreases. On the other hand, if a buyer expects the price to go up in the future, the demand for the good today increases. Explore the role of buyers' expectations as a determinant of demand in this video.

A common error new economic students make is confusing changes in supply with changes in quantity supplied. A change in quantity supplied is a movement along the supply curve in response to a change in price. A change in supply is a shift of the entire supply curve in response to something besides price.

Previously we looked at what happens to the equilibrium price and quantity in a market if supply or demand change. In this video, we explore what happens when BOTH supply and demand are changing at the same time.

In this video, we explore how changes in a few factors affect the demand curve. Changes in income, population, and consumer preferences cause the entire demand curve to shift. Created by Sal Khan.
