a. One approach is for the government to give "vouchers" for fresh fruit and vegetables to families whose income is below a specified level. A voucher is a piece of paper from the government that buyers can give to sellers of fresh fruit and vegetables (farmers, grocery stores, and the like) in payment for fresh fruit and vegetables. (Fresh fruit and vegetable sellers would then submit these vouchers to the government and get paid money that way.) In essence, vouchers are like increases in income that can be spent only on specified products, in this case, fresh fruit and vegetables. Would this plan make fresh fruits and vegetables more affordable? Explain the impact of vouchers on the equilibrium price and equilibrium quantity of fresh fruit and vegetables. Your explanation will be in terms of shifts in demand or supply (or both, or neither) and the effects of any shift. Describe the process by which the shift moves us to a new equilibrium price and quantity of fresh fruit and vegetables
