3. A researcher estimates the following wage equation for underwater construction workers: W = 10 + SD Where W=the wage in dollars per hour and D=the depth underwater at which workers work, in meters. a) Based on this information, draw the offer curve and possible indifference curves for two workers, A and B: A works at a depth of 3 meters and B works at 5 meters. b) At their current wages and depths, what is the rate at which each worker is willing to trade off one more meter of depth while holding utility constant? c) At 3 meters of depth which worker has a greater willingness to pay for a reduction in depth
