Elasticity A. Blue Chair Press publishes art books. The demand for art books published by Blue Chair Press is highly elastic. Labor is a significant input in the production of art books. Show on a demand and supply graph for Blue Chair Press art books the effect of an increase in the wage rate. What can you conclude about the elasticity of demand for labor? (4 points) B. Blue Chair Press uses a lot of labor when it edits and publishes texts. Its labor costs are 80% of its total costs. Compare the elasticity of demand for labor in this situation with the elasticity of labor demand if labor accounted for only 20% of Blue Chair Press's total costs. (4 points) C. Since Blue Chair Press requires very specific artistic skills from the labor it hires, there are few substitutes for the type of labor the firm requires. How does this affect the elasticity of demand for labor? (2 points) D. True or False: The higher the elasticity of demand for the product, art books, the more inelastic is the demand for the resource, labor, that produces the art books. Explain your answer. (2 points) E. True or False: If the ratio of labor costs to total costs is low, then the elasticity of demand for labor is low and a given wage increase results in fewer laborers losing jobs than if the elasticity of demand is higher. Explain your answer.
