For each of the following examples, choose the case with the lower (more inelastic) wage elasticity, evaluated at a common point where the wage is $15 per hour: a. A farm's demand for farm labour for weeding, in a jurisdiction where chemical herbicides are banned for environmental reasons, versus a jurisdiction where they are not. b. A coal mine's demand for labour, where the mine has a local monopoly in the sale of coal, versus a mine that sells coal in a competitive market. c. The demand for workers in a cigarette factory versus the demand for workers in a fast-food restaurant. d. The demand for computer programmers versus secretaries for factories in Silicon Valley. e. The demand for "beer tasters" (quality-control engineers) versus beer production line workers in a brewery.
