Imagine that you’ve just graduated from college and have been offered a position with a firm in New York City. You can’t wait to start living in your own apartment. Your Aunt Bernice, who lives in Brooklyn Heights, has offered you a place to stay while you look for a place to begin living on your own.

Introduction

Imagine that you've just graduated from college and have been offered a position with a firm in New York City. You can't wait to start living in your own apartment. Your Aunt Bernice, who lives in Brooklyn Heights, has offered you a place to stay while you look for a place to begin living on your own.

Learning Objectives

  • Plot a data series onto a bar chart.
  • Read and interpret information from a bar chart.
  • Predict how absence or presence of rent-controlled units impacts the cost of non-regulated housing.
  • Identify shadow markets.
  • Predict how owners of non-regulated housing will vote on rent-control referendums.
  • Describe effects of price ceilings.

Process

New YorkIt's Sunday morning, and Aunt Bernice offers you the obituaries section of the Times. "Here!" she says. "This is the best place to start searching for an apartment."

"Excuse me, Aunt Bernice. I think you meant to hand me the classifieds section."

"No. The quantity of rent-controlled apartments people demand these days is much higher than the quantity currently available. There is a shortage. Since landlords aren't able ration out their supply of rental units by adjusting rates above a certain price, units are rationed on a first-come, first-served basis. In some instances, you must pay an additional fee for the privilege of renting. I suggest you start reading through the obituaries and make a list of newly vacated apartments… before the apartments are listed with an agency or in the newspaper."

Hearing Aunt Bernice's good advice, you're reminded of the day your professor in your Economics 101 course discussed Price Ceilings.

"You do use this stuff in real life," you muse.

You're curious about what residents in areas like New York and San Francisco think about rent control. Surely they understand the allocative inefficiencies of an arbitrarily applied price ceiling. In fact, any time price ceilings are set: utilities, football tickets, parking, etc. — there's bound to be some allocative inefficiencies. You conduct a search on the Web, and identify a couple of sites.

Here's a page from The Library of Economics and Liberty that summarizes the arguments for https://www.econlib.org/library/Enc/RentControl.html .

This page at CNN Interactive named Emotions High as New York Rent Control Deadline Nears summarizes arguments for and against rent control.

  1. Make a list of who wins and who loses under rent control. [Winners: Politicians, tenants who already have an apartment. Losers: People looking for apartments, landlords.]
     
  2. What happens to all of the dissatisfied apartment-seekers? Make a list of alternative rationing devices. [Waiting lists, connections, finders' fees, obituaries, non-regulated substitutes: co-ops, condos, new construction.]
     
  3. How do rent controls affect the following?

    1. Amount of new rental property [Declines.]
    2. Quality of rental property [Deteroriates.]
    3. Age of population [Increases — There's little incentive to move when rent is so cheap.]
       
  4. How would you predict residents of rent-controlled units would vote on a referendum to repeal rent-control laws? [Since it's in the best interest of apartment-dwellers to keep their rent low, they'd likely vote against such a referendum.]

Shadow Markets

The emergence and development of alternative rationing devices to a price-controlled market is called a shadow market. Shadow markets serve as a safety valve for excess demand. The equilibrium prices in shadow markets are often higher than in non-regulated markets.

  1. Provide some examples of shadow market housing. [Condos, co-ops, etc.]

    Let's take a look at some data on apartment advertisements from two markets, New York and Philadelphia, to try to find evidence of shadow markets.
     

  2. Plot each data series below in a histogram, or bar chart.

(Here is how the Philadelphia bar chart should look.)

Rent Chart Two

Once you have your data in bar chart format, take a look at the shape of the distribution of apartment prices.

  1. What's the difference between the New York rental market and the Philadelphia rental market? [The New York market shows two bell-shaped curves, which indicate two markets: the regulated, rent-controlled market and the non-regulated, or shadow, market. The Philadelphia rental market shows a typical distribution of rental units.]
     
  2. What do you predict would happen to the distribution of apartment prices if rent-control were repealed in New York? [It would assume the shape of the distribution of a typical rental market, like the one in Philadelphia.]

The Mortgage Connection

Suppose you are seeking housing in New York City and have been unable to locate an apartment. Since you are a prudent saver and investor, you have some money saved for a down payment for a condominium. You are aware of a forthcoming referendum to repeal rent-control laws, and you believe that passage is imminent.

  1. What do you expect will happen to the value of the condominium you are purchasing approximately one year from now? [Supply of rental units is likely to increase with the repeal of the rent-control laws. With demand remaining stable, prices will decline. Since rental units are substitutes for owner-occupied housing (condos), demand will likely decline. The value of your condominium will also likely decline]
     
  2. Your mortgage lender is also aware of the impending change in the housing market. How would you expect him or her to hedge against the change? [He may ask for a larger down payment to cover any losses in case of a forced sale.]

For The Teacher

Alternative points to consider: In the above rent control problem, we have assumed perfect competition. However, in most large cities, monopoly rents are the rule rather than the exception. If all that is taxed away are the rents, then supply will not change over time. One is just shifting income from one group of individuals to another.

The problem in most cities is that rent controls did not get adjusted for inflation, so that prices fall below the perfectly competitive rate and all of the problems mentioned in the above lesson do occur.

There are economically justifiable reasons for rent control. Prices under non-perfectly competitive solutions do not send the proper signals. Under monopoly conditions, the price would be higher than the pareto-efficient price and government intervention is justified.

There are other forms of rent control that do not lead to the allocation problems alluded to in this lessons: rent stabilization and rent control adjusted for inflation are more likely scenarios.
