The model is commonly applied to wages in the market for labor. The typical roles of supplier and consumer are reversed. The suppliers are individuals, who try to sell (supply) their labor for the highest price. The consumers are businesses, which try to buy (demand) the type of labor they need at the lowest price. As more people offer their labor in that market, the equilibrium wage decreases and the equilibrium level of employment increases as the supply curve shifts to the right. The opposite happens if fewer people offer their wages in the market as the supply curve shifts to the left.
