The basic economics of an import tax

We have had many surprises in the political arena, but perhaps none are more surprising than to see Republicans rallying around a tax increase.  Import taxes are politically convenient.  Gullible voters think that such taxes will be paid by foreign entities and will encourage producers to shift production to the US to avoid such taxes.

This is wrong on both counts.  Consumers in the US end up paying for the tax via higher prices.  As they cut back spending this means fewer domestic jobs in retail.  Producers have developed complex global supply chains to take advantage of productivity and cost differences across different countries. A 20% import tax is not going to be enough to offset a 500% labor cost difference.  

This applies to all industries, including the luxury industry.  See a quote from this expert in Luxury Daily!

Can pet economics tell us something about human health economics?

A recent HBR piece by Liran Einav of Stanford and Amy Finkelstein of MIT compares recent trends. for spending on veterinary care to spending on health care for humans.  They find that total spending on both items has risen more than spending overall, meaning more and more of our budgets are going to veterinary services as well as health care for people.  Spending by income brackets shows the same pattern, with much larger spends for high income than low income households.  Also spending for veterinary care tends to be concentrated in the last months of life, just like human health care.

These similarities are striking in some way because there is no employer-provided veterinary care insurance and there is no Medicare- or Medicaid-like program for pets.  So the trends for pet health spending closely mirror those for human health spending even though the role of government and insurance is quite different in the two markets.

The careful reader will note that Einav and Finkelstein do not address the question of price inflation for veterinary and human health care.  We all know that human health care inflation is much higher than overall inflation.  The picture for veterinary inflation is more mixed.  A research team from Purdue looked at the inflation measure published by the Bureau of Labor Statistics and then developed their own price index based on pet insurance claims submitted to Nationwide.  The BLS veterinary care price index increased by 25%, well above the 12% inflation rare for 2009-2015.  The price index based on the Nationwide index showed no veterinary inflation over this period.  

One last question: if we are spending more and more on our pets' health, are they getting healthier?  Are they living longer?  Are they leading more active lives?  Are they getting more tummy rubs?  Clearly this calls for more research.

NC State online MBA stays in US News top 20

More great rankings news!  For the third year in a row the NC State online MBA has placed in the US News and World Report top 20.  The program placed 18th, tied with Mississippi State and South Florida.

The US News rankings are based on faculty credentials and training, student services and technology, student engagement, peer evaluations, and admissions selectivity.  I am especially proud of how well we scored on the student engagement dimension.

I was fortunate enough this fall to have my first opportunity to teach the online core economics course.  It was one of the best teaching experiences I have ever had.  More people come to your office hours online than they do in day or evening instruction.  Accessibility matters, a lot!

What trade deficits really mean

Harvard's Greg Mankiw explains in this NYT Upshot column what happens when a country runs a trade deficit.  When imports are greater than exports, this results in lower GDP.   But is this something we should really be concerned about?

Mankiw points out that the trade deficit is accompanied by a foreign investment surplus.  When businesses overseas sell more to us than we sell to them, they have to do something with the funds they accumulate.  In practice that means they either end up buying US assets or make physical investments in the US, e.g., Siemens opening facilities here.  And guess what?  The investment foreign companies make in the US is considerably larger than the investments US firms make overseas.  In other words, there are many more cases like Siemens than like Carrier.  

Viewed differently, US consumers are able to have a higher standard of living by being able to import goods from overseas.  Investors overseas are able to invest in a relatively "vibrant and safe" economy.  So why would you want to mess with this?

Deadweight loss during the holidays

Great video on the economics of giving by Marginal Revolutions's Tyler Cowan and Alex Taborrok.

Pop quiz: Suppose you have $20 in your budget for a gift to Aunt Mabel.  How do you make sure that Mabel gets at least $20 worth of enjoyment?  Easy answer: give her $20 in cash or Amazon gift card.

But do we really want to spend the holidays trading $20 bills with each other?  The video brings up other motives for gift giving, but I am not sure making charitable contributions in Mabel's name is the answer.  She might rather have the $20.

Saving jobs at what cost

I have been searching for the words to express how exasperated I am with United Technologies' decision to keep 700 or so jobs in its Carrier plant in Indianapolis.  Kudos to Larry Summers, today in WP, who totally nails it.  In a market system based on stable regulations and enforced laws, everyone plays under the same rules.  Who you are does not matter.  In a system based on ad hoc deals, all bets are off and companies will redouble their efforts to make friends in high places in government.  

Money quote:
Most companies will prefer the good to the bad will of the U.S. president and his leadership team. Should that reality be levered to get them to locate where the president wants, to make contributions to the president’s reelection campaign, to hire people the president wants to see hired, to do the kinds of research the president wants carried out, or to lend money to those that the president wants to see assisted?
Some of the worst abuses of power are not those that leaders inflict on their people. They are the acts that the people demand from their leaders. I fear in a way that is more fundamental than a bad tax policy or tariff we have started down the road of changing the operating assumptions of our capitalism. I hope I am wrong, but I expect that as a consequence we are going to be not only poorer but less free.

Economists weigh in on Fidel

Two blog posts from well-known economists:

1) Tyler Cowan's forecast for the Cuban economy after Fidel is not very rosy.  Cuba has a foreign debt challenge and can no longer count on cheap oil from Venezuela.  Sugar prices have increased this year but remain depressed.  The best case scenario, Cowan argues, is that Cuba catches up with the Dominican Republic in a few decades.

2) George Borjas spent the first 11 years of his life in Cuba, leaving with his mother after his family's business had been confiscated.  He shares his remembrances about life under Fidel in the early 1960s in this blog post.  Borjas reaction to the news of Fidel's death: "Good riddance!"

Machine Intelligence

Twenty years ago the internet was supposed to "change everything" and defy conventional economic analysis.  Nope.  Did not happen.  The internet lowered the cost of search, information, and communication.  New products spawned by the internet were characterized by massive fixed costs and negligible variable costs.  Key insights about the internet continue to follow from basic economics.

Now the hype is about machine intelligence.  Three faculty members at the Rotman School of Management at the University of Toronto have a short article on the HBR website where they argue that the economics of machine intelligence can be summed up as "lower costs of prediction."  This means that firms will have lower costs associated with demand forecasting and inventory management, leading to wider adoption of these practices.

As prediction becomes cheaper, there will be an impact on other inputs into the production process, depending on whether they are substitutes or complements for prediction.  For instance economists who make predictions may be displaced by machines.  The authors think that judgment skills will become more important, serving as a complement to cheaper predictions.  I am not sure what they mean by judgment skills, but presumably they are referring to cognitive processes where humans will continue to have an advantage over machines.

Machine intelligence will soon be coming to higher education.  Some business schools are already experimenting with using tools based on machine intelligence to drill newly admitted students on basic skills in math and statistics.  Will a machine-based socratic dialogue be next?

Immigrants making America great

If you want to understand why America has been the world leader for so many years in technology, you might want to pay some attention to the key role played by immigrants.  This report from the American Enterprise Institute (right-leaning DC think tank sure to supply many appointees to the Trump administration) shows that

  1. Fifteen of the top 25 tech companies were founded by first or second generation immigrants
  2. A fifth of the Inc. 500 firms are headed by immigrants
Legitimate disagreements can be had concerning illegal immigration and the number and mix of legal immigrants to the US.  As these discussions play out, everyone needs to be well aware of the vital role immigrant entrepreneurs play so that we avoid decisions that keep the father of the next Steve Jobs in Syria.

Economists find recipe for charter school success

The evidence on the effectiveness of charter schools is mixed at best.  But a recent study by  economists from MIT and other schools (that was featured in NYT recently) shows that one type of charter school has been consistently successful -- schools that set high expectations for students and high levels of support for teachers and students.

The research team followed charters in the Boston public schools.  Lotteries determine who gets into charters, so there is a real experimental design to the research.  Those fortunate to get into charters learn more in school and are more likely to go to college.  Most of the charter students come from low income families and are learning at the same level as those in public schools from upper and middle income families.

One researcher noted that the impact of the charter environment was far greater than variables such as class size and new buildings.  Another, who used to be a union organizer, said the gains from these charters were the largest she had ever seen in her career.

Yesterday Massachusetts voted on a referendum to significantly expand charter schools.  It lost 62 to 38 percent.

NC State MBA rated in Global Top 100 by the Economist magazine

More kudos for the NC State Jenkins MBA!  The program was ranked #89 in the world by the Economist magazine in its annual Which MBA? rankings.  This is the first time our program has appeared in a global top 100.  NC State placed #24 among public universities in the US.  This will certainly help raise its reputation, especially among prospective students overseas.

Globally NC State stood out in the following areas:

  • #10: % of graduates with jobs within three months of graduation.  
  • #12: faculty quality
  • #14: salary growth (post-MBA divided by pre-MBA salary)
Highly half of the top 100 programs were in the US, with most of the rest in Europe.  The top five programs were Chicago, Northwestern, Virginia, Harvard and Stanford.

NC State MBAs excel at case competitions

In two recent case competitions, teams representing the NC State Jenkins MBA team have excelled.  At the National Black MBA Conference in New Orleans, 34 top-tier schools competed.  NC State's team placed second, just behind the University of Michigan.  Other schools that competed include Boston University, Cornell, Emory, Georgetown, MIT, Ohio State, Penn State, Purdue, Rice, Rutgers,  Southern Cal, Texas A&M, UCLA, UNC-CH, and Vanderbilt.  

Kudos to David Satterfield, Rudhawarsh Loganathan, Chandan Dash, Malcolm Scott, Aarathi Sree Srinivasan, and Vishnu Kotipalli for representing the program so well.  Rudhawarsh also was one of six contestants recognized as one of the best presenters in the first round.  Also at National Black, Jelyse Dawson finished fourth (out of 300) in the Innovation Whiteboard Challenge.  

Kevin Weisner's team finished in first place in the US division of the Novo Nordisk Innovation in Action Case Competition.  Kevin goes to Denmark in two weeks to compete against a Danish team for the global championship.  

NC State is hosting its first case competition starting tomorrow, the NC State Grand Business Challenge sponsored by Merck.  There will be nine other schools competing

How are those pay raises working out for Walmart?

In early 2015 Walmart made a strategic decision to start paying higher wages to store employees.  Starting pay went up to $10/hour with department managers getting bumped up to $15/hour.  Walmart also started investing more in training that would make workers promotable.  What happened?

According to a recent NYT article, the good news is that customer satisfaction and sales have both increased.  The not so good news is that profits have lagged the averages for S&P Retail and the S&P 500.  Managers report that Walmart is now attracting a different sort of employee, one looking for a career instead of just a job.  Productivity seems to be higher as well.  Conceivably the profit situation will turn around once enough workers have been trained that Walmart can get a return on the training investments.

Regulating driverless cars

According to WP, the National Highway Traffic Safety Administration is in a big hurry to issue "aggressive" regulations on driverless cars.   The regulations are likely to encompass "how and where they expect their vehicles to operate, how they will interact with other cars and the roadway, how they validate their testing, how they intend to protect privacy and prevent hacking, and how they would share data collected by onboard computers."

Two ways of looking at this.  The good news is that one set of federal regulations will make compliance easier than 50 sets of state regulations.  The not so good news is that the feds are insisting on pre-market approval with testing monitored by an independent party.  This looks like a sure way of putting the US behind other countries in the race to develop this new technology.  

Driverless car experiments are already taking place.  Hopefully the industry and the regulators can wait until there is more certainty about how such cars are likely to operate before coming up with a regulatory framework.

An incentive plan fiasco at Wells Fargo

NC State online MBA students have been studying incentive plans this semester.  The main motivation behind such plans is to change employee motivation to generate additional net income for the employer.

This week's revelations about Wells Fargo show how a poorly designed plan can backfire.  WF wanted its employees to cross-sell more accounts, e.g. get someone with a checking account to take out a mortgage.  Employees ended up with aggressive sales targets and thousands of them created new accounts without the customer's knowledge so that they could collect bonuses.

Maryland Smith Professor Clifford Rossi argues that none of the traditional lines of defense against such behavior held.  Line managers did not hold front line employees accountable until it was too late.  Corporate risk management missed all signals as well, ditto for internal audit.  According to WSJ, only 10% of the 5000+ employees who have been fired were at the branch manager level or higher.  No senior officers have departed yet.

While the plan was in effect the number of Wells Fargo products per household rose from 5.5 to 6.4 over a four year period.  And the four year period was 2009-2013, not exactly a time when people were taking out second mortgages to buy a new vacation home.

NYU finance prof Kermit Schoenholtz argues in the New Yorker that enforcement of financial regulations depends on bank self-monitoring.  Right now, that "mechanism isn't working."  Fines are supposedly designed to punish wrongdoing and send a message that banks will pay a stiff price if caught.

Wells has been fined $185m.  Net income in the 2nd quarter of 2016 was $5.6 billion.  The CEO John Stumpf still has his job.

Forced grade distributions

Wharton management prof Adam Grant argues in a recent NYT op-ed that colleges should not use forced distributions when handing out grades.  In a forced distributions, there are limits on the number of students who can receive a particular grade, e.g., only 25% can get A's, the next 35% can get B's.  This type of system is in place in core classes at many of the world's leading business schools.

Grant sees two serious defects: one related to fairness and the other related to collegiality.  The forced curve might say there can only be ten A's in a class, but what if 15 students have performed at A level?  What if only five students perform at A level, do the other five get an A anyway?  Experienced professors who have taught the same course year after year are in a very good position to make sure grades are equitable relative to standards, Grant argues.  As for collegiality, forced distributions turn classmates into adversaries in what Grant calls a "zero-sum game."

Forced distributions do prevent grade inflation.  Today over 40 percent of all grades are in the A range.  Grant in essence is arguing whether the cure is a larger danger than the disease.

Closing note:  there are no forced grade distributions in the NC State MBA program.

Is the NFL leaving money on the table?

So argue two WP economic writers.   Their basic point is that the NFL could relocate some of its teams and create a stronger revenue stream and global brand presence for the league.

The recent move of the Rams from St. Louis to Los Angeles underscores the basic idea: some very large US markets are not being served.  So the article suggests that San Diego Chargers head to Orange County, the Buffalo Bills move to Brooklyn, the Cincinnati Bengals move to Vegas and the New Orleans Saints move to Austin-San Antonio.

But wait, there's more.  Why not move franchises to Jacksonville to London, Detroit to Toronto and Cleveland to Mexico City to create a true global presence?  Better do it quick before Clinton or Trump imposes a relocation tax!

My only pushback is whether relocation makes more sense than expansion.  And why not have games  on Tuesday and Wednesday night?

Big data creates big opportunities for economists

More economists are getting jobs in Silicon Valley to mine insights from data sets that NYT calls a "Candy Store."  Amazon currently has 34 job openings for economists, with top pay of $200k per year plus bonuses and options.  Airbnb recently hired an economist away from Harvard Business School.

In addition to higher pay than they would receive in academic settings, Silicon Valley firms offer economists the opportunity to work with transactional and click data that are not ordinarily available for research.  They can conduct experiments on questions dealing with pricing, promotions and workplace incentives.

At the same time more and more economists are keeping their academic positions and consulting for companies such as Microsoft.  The likely result is economic research that is better executed and more meaningful for businesses.

Taxes due versus taxes collected

Catherine Rampell's WP blog examines the question of how much tax cheating is taking place and how much federal revenue might change if the problem were addressed.  Studies show that the feds collect about 84 cents of every dollar legally owed.  If the IRS were able to collect all taxes legally owed, it would collect an additional $600b, which is larger than the federal budget deficit of $590b.

Rampell recommends simplifying the tax code and increasing the IRS budget for enforcement and customer service.  It will not result in 100% compliance, but would get us closer to that goal.

On EpiPens

Ever since an unfortunate encounter with some smoked salmon imported from China, I have been buying EpiPens for 10 years.  Fortunately the state health plan has shielded me from the tremendous price increases that Mylan has been imposing, now up to $600 for a two-pack.

Most of the discussions in the mass media have been of the predictable shame-shame-on-you variety.   Scolding pharma is a good way to vent, but does it really get to the heart of the issue?  Wouldn't any company raise prices 600% if they could get away with it?  I do not normally pull items from other economics blogs, but this article from Slate Star Codex that is featured today on Marginal Revolution is both informative and (in parts) hilarious.

Here are the informative parts:
1) A number of companies have developed EpiPen substitutes but they keep getting rejected by the FDA.  In contract there are eight competing EpiPen-like products in the EU.
2) There is an approved substitute called Adrenaclick but most doctors are unaware of it and keep prescribing the EpiPen.
3) Mylan spends heavily on lobbying to keep things the way they are.

Here is the funny part:


Imagine that the government creates the Furniture and Desk Association, an agency which declares that only IKEA is allowed to sell chairs. IKEA responds by charging $300 per chair. Other companies try to sell stools or sofas, but get bogged down for years in litigation over whether these technically count as “chairs”. When a few of them win their court cases, the FDA shoots them down anyway for vague reasons it refuses to share, or because they haven’t done studies showing that their chairs will not break, or because the studies that showed their chairs will not break didn’t include a high enough number of morbidly obese people so we can’t be sure they won’t break. Finally, Target spends tens of millions of dollars on lawyers and gets the okay to compete with IKEA, but people can only get Target chairs if they have a note signed by a professional interior designer saying that their room needs a “comfort-producing seating implement” and which absolutely definitely does not mention “chairs” anywhere, because otherwise a child who was used to sitting on IKEA chairs might sit down on a Target chair the wrong way, get confused, fall off, and break her head.
