Explain how each of the following programs would effect the elasticity of demand for teachers in public education and if so, in which direction.

A. State and federal funding to reduce maximum permissible class sizes under NO CHILD LEFT BEHIND LEGISLATION.

B. Teachers' Union negotiating smaller maximum class sizes.

C. A union negotiated increase in teachers' salaries.

D. An increase in the supply of highly qualified teachers' aides

A. State and federal funding to reduce maximum permissible class sizes under NO CHILD LEFT BEHIND LEGISLATION.

Reducing the maximum class size implies more number of sections of each class. It will require more teachers. Therefore, elasticity of demand for teachers will be high and in the right direction.

B. Teachers' Union negotiating smaller maximum class sizes

The teachers? union demanding smaller number of maximum class size increases the requirement of teachers. Therefore, elasticity of demand for teachers will be high and in the right direction.

C. A union negotiated increase in teachers' salaries.

An increase in the salary of teachers implies an increase in the cost or price of teachers. An increase in the price of teachers will lead to a fall in their demand. Therefore, elasticity of demand for teachers will fall and will be in left direction.

D. An increase in the supply of highly qualified teachers' aides.

An increase in the supply of highly qualified teachers will reduce their prices. It will not affect the demand side factors. Therefore, with the given information of supply, elasticity of demand cannot be calculated.
