Purchasing power

 example: I teach in another online university that pays me the same compensation per course since year 2010. I have politely asked one month ago if the amount was going to be the same in year 2017. One hundred dollars in year 2010 are $ 114 today. The answer was that they are not thinking in "increasing" the salaries this year. 

As the purchasing power of this compensation has declined, I have four alternatives:

1. Work more, for example increasing the numbers of hours dedicated to tutoring,

2. Buy less expensive goods (drink water instead of Tropicana Orange Juice).

3. Reduce the time I spent with the class (it means reduce the quality of teaching).

4. Quit in that university and look for another job.(in another university or in a private company).

Read about the income and substitution effects and give me your advice. Explain your answer. Provide references
