A Price Ceiling Has Unintended Consequences

Asked if it makes sense to mandate lower rents for some apartments in large cities, many of us say yes. Lower rents facilitate diversity and they enable middle income municipal workers to live close to home. Affordability is good. Yes?

The residents of Cambridge, Massachusetts displayed their support for rent control when they voted to continue it in 1995. However, because the rent control mandate lost in a statewide referendum, Cambridge residents were defeated.

Maybe, though, they really won.

Looking closely at the impact of capping apartment rents on all properties built before 1969 in Cambridge, 2 researchers uncovered a steep downside. Reducing rents 25% to 40% lower than nearby apartments made the value of all housing– controlled and non-controlled–decline. In addition, for rent controlled properties, the peeling paint and loose railings were examples of generally poor upkeep. And, as all econ books remind us, rent ceilings create shortages because, at a lower price, more quantity is demanded than the amount supplied.

After 1995, when the controls were lifted, assessed values rose. For previously controlled properties, they went up approximately 20%. For non-controlled buildings, the increase was even more. Totally, the amount values rose from 1994 to 2004 because rent control ended was estimated as close to $1.8 billion.

Our bottom line: The connection might seem distant but let’s return to a previous post on price gouging. Both rent control and anti-price gouging laws sound like attractive public policies with considerable voter appeal. However, both have negative externalities– a harmful impact experienced by an uninvolved third party–that represent the hidden cost we all pay.

A final fact: There are approximately 1 million rent controlled units in NYC.

If you want to read more about rent control, here is the story of a challenge in NYC that involved the Supreme Court. For anti-price gouging laws, here is what NJ Governor Christie is enforcing and here is a criticism.

ice cream bars_000016946613XSmall

Our story begins in 1920 with some ice cream, some chocolate and a stick. A candy maker decided to coat the ice cream with the chocolate, insert the stick and freeze it. Patenting the stick idea, he created the first ice cream bar and called it a Good Humor Ice Cream Sucker.

Privately owned, then publicly owned, and finally purchased by a Unilever subsidiary, Good Humor is a part of a multinational family. Its sister firms include Ben & Jerry’s, Breyer’s, Popsicle, Hellman’s mayonnaise and Vaseline.

Being a part of a large family is not always ideal. Unilever has made some supply decisions that are creating Good Humor shortages for ice cream truck owners.

During most of this summer, Mr. Ding-A-Ling Ice Cream Inc, owner of more than 60 ice cream trucks, will not have the most popular Good Humor product, their Toasted Almond Bar. The reason? Not only is Unilever closing a Maryland Good Humor factory but also it needs inventory for an expanded ice cream selection–including super premium Magnum bars– in convenience stores. That means less for Mr. Ding-A-Ling and other neighborhood ice cream trucks.

So, if you live in the Northeast and your Mr. Ding-A-Ling Good Humor truck has no Toasted Almond Bars, and you can’t even get a Chocolate Eclair or Oreo ice cream as a substitute, the reasons relate to demand and supply, inventory decisions and international trade. Add to that the patent for the stick and the entrepreneur that created Good Humor 92 years ago, and we can say that ice cream is more than just a dessert.

Another ice cream fact: While there was no ice cream on a stick in 1920, there were ice cream cones.  That “eureka” moment occurred at the 1904 St. Louis World’s Fair when an ice cream vendor ran out of cups and a nearby waffle maker probably offered to help out.

This lighthearted article from WSJ about Good Humor’s Toasted Almond Bar shortages is a good way to learn about ice cream history and to form the economic connections. Also, here is some Good Humor history.

Reading that a Venezuelan retiree did not mind the food lines, I started thinking about how President Chavez’s price controls have changed incentives. The retiree, who has more time than money, now has the incentive to stand in line. Meanwhile, a business owner, seeing profits erased by price controls has the incentive to produce less.
When a ceiling on prices increases the quantity that people demand while decreasing the quantity that producers supply, the result is Venezuelan shortages of the basics like powdered milk, beef, chicken, vegetable oil and sugar.

The bottom line: A government established price creates distorted incentives for buyers and sellers. The long lines, pajama tops without buttons, and grouchy salespeople that characterized the former Soviet Union are perfect examples of the results of distorted incentives.

This NY Times article tells more about price controls in Venezuela. Also, you might enjoy seeing this sign from a Venezuelan store that is posted here.

Peanut prices respond to demand and supply

Farmers decided to plant fewer peanuts when cotton prices soared. The result? Now peanut prices are skyrocketing. Here is the story.

Perhaps it all began with higher cotton prices. Responding, peanut farmers switched some acreage to cotton. Combine that decision with an unusually dry growing season in Georgia, the leading peanut producer, and too many scorched nuts and what do you get? A peanut shortage.

What will happen because of the peanut shortage? Peanut butter will cost us 40% more. And, to be sure they have enough of their basic peanut butter products, Smucker, the world’s largest peanut buyer, has temporarily stopped producing its reduced-fat creamy spread.

The NY Times said we had an acreage war between food and clothing. And here, a past econlife post discusses cotton prices.

The Economic Lesson

The peanuts story is a classic economics tale. On a supply and demand graph, the supply curve shifts upward and to the left when producers switch to a more attractive alternative. The result is less supply and a higher price.

An Economic Question: Now that peanuts are so pricey, what might you predict is the next supply curve move?

Last week, the Boston area had undrinkable water for several days. Predictably, bottled water sales soared as did bottled water prices in certain stores.  Equally predictably, politicians condemned the increases. Most economists, though, disagreed.

As explained by a Boston Globe journalist, price boosters best served the public interest because they had the incentive to supply more water. Yes, price could even double but, as he describes, “…sales of water are slower [than at the cheaper vendor] and there is a lot of grumbling about the high price. But even late arriving customers are able to buy the water they need…” By contrast, the lower priced vendor had “his entire stock cleaned out.”

The riddle: How can high prices make people happy? 

The answer: When they preserve the supply of a necessity.

The Economic Lesson

Picture a supply curve sloping upward crossed by a demand curve sloping downward. Price is the y-axis and quantity is the x-axis. As price rises, producers are willing and able to create and sell more. Why? Because higher prices mean higher profits. Whenever government steps in and prevents price from naturally rising as the market dictates, shortages result. Do you prefer high or low water prices for Boston?
