- In 2011 the United States federal government decided that all businesses must pay their employees a minimum wage of $7.25 per hour. However, state governments could decide that businesses in their states should pay their employees more than the $7.25 per hour. Below is a graph of hourly minimum wage requirements for five states. Use the information provided in the graph to decide which of the following statements is NOT TRUE! New York's hourly wage requirement is about the same as the federal minimum wage requirement. The hourly wage in Ohio is more than $1 above the hourly wage in Minnesota. Oregon has the highest hourly wage requirement at over $8.00 per hour. The hourly wage in New York is more than double the hourly wage in Georgia.Consider the market depicted in the graph and assume the government imposes a price floor of P2. At P2, 150 units of the good are supplied (wish to be sold) and 50 units of the good are demanded (wish to be bought). Choose the correct ones: Without an enforcement mechanism, the effect of a binding price floor will be negligible because it will simply be ignored because buyers and sellers enrich themselves by trading below the floor price. With an enforcement mechanism, the effect of a binding price floor may still be negligible if the enforcement mechanism is easy to evade or doesn't impose a significant penalty for selling below the price floor. Without an enforcement mechanism, the effect of a binding price floor will be negligible because it will simply be ignored because buyers and sellers enrich themselves by trading above the floor price. With an enforcement mechanism, the effect of a binding price floor may still be negligible if the enforcement mechanism is easy to evade or…2. Consider the following graph: Which statement is false?
