36 7. If more people are willing to work as salespeople at every wage, this [an increase/a decrease/a movement along] demand for labor. If the wage for hotel salespeople increases, this [an increase/a decrease/a movement along] demand for labor.

If technology improvements allow each salesperson to sell more rooms per hour, this is [an increase/a decrease/a movement along] demand for labor.

When hotel salespeople have a dominant substitution effect, the quantity supplied of labor [increases/decreases/remains the same/changes ambiguously] as the wage rises. When hotel salespeople have a dominant income effect, the quantity supplied of labor [increases/decreases/remains the same/changes ambiguously ] as the wage rises. 9. If the market price of hotel rooms were to double, all else equal, we would expect the prevailing wage in the hotel salespeople market to [increase/decrease/remain the same/change ambiguously]. If the productivity of salespeople were to double, all else equal, we would expect the prevailing wage in the hotel salespeople market to [increase/decrease/remain the same/change ambiguously]. If the number of people who want to be salespeople were to double, all else equal, we would expect the prevailing wage to [increase/ decrease/ remain the same/change ambiguously]
