7. Suppose that the value of Price Elasticity of Supply for pens is 2.5. This value would suggest that a 1% increase in the price of pens would result in supplied A. increasing by approximately 4%.

Greg, Peter, and Bobby are debating the potential effectiveness of decreasing drinking by imposing higher per unit taxes on alcohol. Greg states that, The most effective way to substantially decrease consumption would be to impose the tax on buyers if supply is very elastic and instead impose the tax on sellers if demand is very elastic. Peter claims that, In terms of discouraging consumption, it doesn t matter if we tax buyers or sellers. In either case a per unit tax of $T would decrease consumption by the exact same amount. Bobby argues that, The only way to reduce consumption would be to tax buyers directly, because if the tax is imposed on sellers it is hidden from buyers and nobody will change their behavior in the marketplace. Based upon our discussion in lecture, A. Greg s statement is the only correct statement. B. Peter s statement is the only correct statement. C. Bobby s statement is the only correct statement. D. None of the statements are correct. 9. When the price of corn is $4, the demanded of corn is 5.

Imposing a price ceiling will generally A. decrease the traded of the good. B. make all sellers of the good worse off.

For questions 2 and 21, consider the two different demand curves illustrated below: price Demand B 18 Demand A 15 Demand A Demand B 2. If the value of Price Elasticity of Demand along Demand B at a price of $18 is 1.23, then the value of Price Elasticity of Demand along Demand A at a price of $18 must A. be greater than (i.e., closer to zero than) 1.23.

Answer questions 31 through 33 based upon the estimated values of elasticities stated below: (Price Elasticity of Demand for X ) = 1.33 (Price Elasticity of Demand for Y ) =.92 (Income Elasticity of Demand for X ) =.45 (Income Elasticity of Demand for Y ) =.27 (Cross Price Elasticity of Demand for X with respect to the price of Y ) =.59 (Cross Price Elasticity of Demand for Y with respect to the price of X ) =.62 31.
