Tesla Model S

Electric carmaker Tesla just announced its first profitable quarter. I also learned it was able to add $40.5 million to its bottom line for selling pollution credits to other auto makers.

States like California have a zero emission requirement for a proportion of the cars sold by each automaker. Too small to have the emission mandate, Tesla sells its credits to other auto manufacturers. The pollution credits are earned (or owed) with each car sale.

Both accomplishments started me thinking about tradeoffs. Electric cars are environmentally friendly because they do not spew carbon emissions. They might be less friendly, though, than most of us expect.

Here is the story:

The environmental impact of an electric car starts sooner and ends later than its road life. One academic study concluded that, “The supply chains involved in the production of electric powertrains and traction batteries add significantly to the environmental impacts of vehicle production.” It added that vehicle parts disposal and material add to cost. But, researchers also said that some vehicles can be so environmentally beneficial that they offset the costs.

How then to assess a firm’s environmental ledger? With Tesla, we can place a federal loan, the state carbon credits, manufacturing and disposal on the liability side. Its benefits focus on road use.

Our bottom line: Looking at environmental friendliness, we might not see the hidden tradeoffs.

Sources and Resources: The name Tesla and its image belie a more complicated story. Supported by government subsidies and benefiting from carbon credits, Tesla is a perfect example of the complexities of assessing environmental impact. The academic article on “cradle to grave” considerations, a WSJ article and a Timothy Taylor discussion are, respectively, here, here, and here. As a result, this and this article about Tesla were only a part of the environmental story.

The Supreme Court same-sex marriage case is really about government catching up with life.

More than 4 decades ago, Nobel laureate Gary Becker explained that we could view the family as a business firm. In order to produce income and run a household, the firm “employed” husbands and wives. With a predetermined division of labor, the husband managed the income and the wife, the household.  Specialization generated more efficiency.

Fast forward to 2013. With a growing number of heterosexual couples and with same-sex couples, traditional roles have been upset because both work outside the home. It no longer is necessary for opposites to attract. Instead, as economists Justin Wolfers and Betsey Stevenson say, we have “hedonic” marriage in which there is more “productivity” when people with similar skills and interests form a pair.

However, the US government has not yet recognized that the family as an economic unit has changed. Perhaps then, we could say that the Supreme Court same-sex marriage case, United States v. Windsor, is actually about catch up. Federal regulations need to catch up with the realities of contemporary marriages and families.

As a result, described by Professor Lee Badgett, the federal government still favors heterosexual married couples. To be exact, in 2004, the US General Accounting Office cited 1138 benefits “…in which marital status is a factor in determining or receiving benefits, rights and privileges.”

Or, we could be talking about $500,000.

Income taxes, estate taxes and and gift taxes are impacted by marital status. For health insurance, when an employer does not offer same-sex domestic partner insurance, then paying for private insurance is the alternative. Add to that an inability to qualify for Social Security spousal benefits and other retirement plans and the lifetime loss could be close to $500,000. In the current Supreme Court case, the $363,053 estate tax was the most publicized figure.

Conveying some cost benefit analysis, a 2009 NY Times article presented the details. Their hypothetical same-sex couple was 2 women with 2 children who together earn $140,000 in 2 different proportions. Called the best case, the split is $70,000/$70,000 (top bar on graph below); the worst case is $30,000/$110,000. Each bar shows how they would differ from a similar heterosexual couple. Based on these couples, the cost could be $500,000. The only financial benefit came from the income tax “marriage penalty” which meant, in these 2009 graphs, that married couples pay more income tax than same-sex couples.

Marriage Makes Health Insurance Less Expensive.

Marriage Makes Health Insurance Less Expensive. Worst case refers to same-sex partners with unequal income while with best case, each earns the same amount.

Sources and Resources: Hat tip to Julian at Imagodigital for sending me the ABC News article about the economics of same sex marriage. The ABC News article led me to Professor Badgett’s academic perspective and the NY Times, “The High Price of Being a Gay Couple,” my source of the above graphic. Finally, a Bloomberg article by economists Justin Wolfers and his domestic partner Betsey Stevenson about Gary Becker’s work and hedonic marriage was the ideal complement to the more traditional discussion of the economics of same-sex marriage.

Thank you grunge stamp isolated on white

I never realized the cost of saying, “Thank you.”

Assume for a moment that you receive a text that you appreciate. Should you reply with a thank you? One NY Times reporter suggests that your decision relates to texting etiquette. However, I suspect it really is about cost benefit analysis.

Defined economically as sacrifice, the cost of unnecessary texts and emails is huge time that might be spent elsewhere. But, the catch is that the cost is higher on the recipient’s end. If so, doesn’t the sender have the incentive to send unnecessary communication?

Maybe not. Gradually, the social norms for communication are changing.

With the first telephone, no one knew to say hello when you began speaking. Then, someone figured it out and it stuck. Now, with new communications media, again social conventions are evolving. For many people, a lone “thank you” is digitally inconsiderate.

I wonder though, if saying thank you brings the benefit of graciousness to our society. And, does the benefit to all of us outweigh the individual cost?

Your opinion?

Sources and Resources: My pondering the new media “rules” began with a NY Times ”Bits” article on texting, email and voicemail etiquette. Conveying more detail, this Washington Post article provides more cost benefit analysis of texting. Surprisingly, one college professor says his students are writing better because of texting.

Please note that the title of this entry was slightly edited after it was posted.

Oscar

An Oscar could be worth 4 years.

  • Hypothesizing that higher social status can extend a life, researchers report that actors who win an Academy Award can expect to live 3.9 years longer than those who lost. Their conclusions were based on data from 72 years of awards that included 235 Oscar winners, 527 non-winning nominees and a control group of 887 performers who were never nominated. (We should note that their statistical methods have been challenged.)

 

An Oscar could cost $900.

  • Weighing 8 1/2 pounds (yes, heavier than it appears) and 13 1/2 inches tall, Oscars have a 24-carat gold plated exterior. Mostly though, they are made of Britannium, an alloy composed of tin (93%), antimony (5%) and copper (2%) and cost $900.

 

Or, more than $2 million.

  • Currently, award winners are only permitted to sell their statuettes back to the Academy for a small amount but pre-1950 recipients have no constraints. The best picture Oscar that went to Gone With the Wind in 1939 was purchased by Michael Jackson for $2,125,743.

 

And always, an Oscar costs the time it takes to write an acceptance speech.

In an analysis of Oscar speeches since 1971, the Guardian’s movie blogger reported the frequency of words and phrases that winners expressed. Here are some examples that I particularly liked:

  • 15 thanked their high school teacher.
  • Meryl Streep said, “Holy mackerel.”
  • 181 wives were thanked but only 37 husbands
  • 125 moms were thanked but only 81 dads
  • Only 24 said, “I would like to thank my children.”
  • 73 said, “Wow.”

 

Sources and Resources: The 2001 Redelmeier/Singh study (gated except for first page) and this NY Times article on Dr. Redelmeier’s work explain how he concluded that Oscar winners live longer. By contrast, saying the Redelmeier/Singh study displayed “healthy performer survivor bias,” this paper disagrees. For more about the physical composition of the statuette, this article provides the details while the resale value is described here. And the Guardian blog on acceptance speeches was fun.

Plunging arrow...16673_7.8_000000061495XSmall

Several days ago, during a phone call, I was asked to “hold” for a moment. 5 minutes passed. No one returned. I considered hanging up but thought, I’ve already waited 5 minutes. They will have been wasted if I leave. 10 minutes passed. Still no one.

The Jets are having the same experience with their quarterback. Paid $8.25 million next year whether he plays or not, Mark Sanchez has had 2 mediocre seasons. Just as I waited 5 minutes, and then 10 minutes, the Jets too feel they have an investment.

My 10 minutes and their $8.25 million are “sunk costs.” Whatever we paid is gone. Thinking rationally, we should look to what the future will cost us. More time waiting on the phone? More losing games?

According to one psychologist who has studied sunk costs, the bigger the past cost, the more unrealistic people are about its rosy future potential. Because they perceive waste and even harm to a reputation, people demonstrate “cognitive dissonance,” an unrealistic assessment of their future behavior. As a result, they continue the behavior rather than accepting a loss and moving on.

So, as Boeing ponders problems with its 787 Dreamliner and you decide whether to wait for the end of a boring video, your sunk cost should not affect your decision about continuing. Instead, compare future cost and benefit.

Sources and Resources: Thanks to James Surowieki for an excellent New Yorker column on sunk costs that took me to psychologist Hal Arkes’s study of sunk costs. More on athletes and sunk costs is here.
