explain the expected impact on output, price level, and employment if new government regulations require firms to use a cleaner technology that is also less efficient than what they previously used?

Just a year after you launched the expansion of DWJ, inflation has raised your marginal cost by 7% from $198.33 to $212.21. Your elasticity varies for each of the three regions in which you sell your DWJ brand. In the southwestern region, your elasticity is -2.76. In your upper-western region the elasticity is -3.50. In your New England region the elasticity is -5.76.Use %ΔQd/%ΔP = e to estimate the percentage decrease in quantity demanded if you were to raise prices in all three regions by 7%. (Do not include the negative sign when recording your answer.)a. %ΔQd Southwestern  b. %ΔQd Upper-western  c. %ΔQd New England

Please help; I'm confused on this one. I got d as my answer, but I feel the correct answer should be (C), an increase in supply since the marginal cost is being increased due to work safety regulations.

The time period in which producers cannot increase their use of economic resources to increase quantity supplied is the:   Multiple choice question.   immediate period.     short run.     long run.     fiscal period..
