Answer:
a. Difference in values
b. a. Rent ceilings reduce the quantity and quality of available housing.
Step-by-step explanation:
The disagreement between these economists is most likely due to difference in values.
Economists are known to disagree a lot with each other and this is down to them having different values and perspectives with regards to several economic decisions. This is why there are different economic theories subscribed to by economists such as Keynesian and New Classical theories.
Despite these disagreements however, there are certain things they would always agree on and one of those is that rent ceilings reduce the quantity and quality of available housing.
The logic behind this is that imposing a rent ceiling would dissuade real estate investors from putting in more money to develop properties because the rent ceiling would limit the returns that they can get.
Supply of real estate would also fall because less investors would go into the market because they would fear being unable to recoup adequate returns on account of the rent ceiling.
