Where would the economy of this quadrant of the galaxy be without the entrepreneurial spirit of the Ferengi? What is the foundation for their insatiable thirst for profits? It must be the aphorisms, guidelines, and principles called the Rules of Acquisition.
Rule number 1 is "Once you have their money, you never give it back."
My two favorites are
Rule 34: War is good for business
Rule 35: Peace is good for business.
And the one that has saved me more times than I can count
Rule 59: Free advice is seldom cheap.

A Reversal Of Structural Unemployment?
See Supermarkets start bagging self-serve checkouts: More supermarkets bagging do-it-yourself checkout lanes in name of customer service by Stephanie Reitz of the Associated Press. Excerpt:
Here is what I say about in class (which we covered this week):
"Big Y Foods, which has 61 locations in Connecticut and Massachusetts, recently became one of the latest to announce it was phasing out the self-serve lanes. Some other regional chains and major players, including some Albertsons locations, have also reduced their unstaffed lanes and added more clerks to traditional lanes.
Market studies cited by the Arlington, Va.-based Food Marketing Institute found only 16 percent of supermarket transactions in 2010 were done at self-checkout lanes in stores that provided the option. That's down from a high of 22 percent three years ago.
Overall, people reported being much more satisfied with their supermarket experience when they used traditional cashier-staffed lanes.
Supermarket chains started introducing self-serve lanes about 10 years ago, touting them as an easy way for shoppers to scan their own items' bar codes, pay, bag their bounty and head out on their way. Retailers also anticipated a labor savings, potentially reducing the number of cashier shifts as they encouraged shoppers to do it themselves.
The reality, though, was mixed. Some shoppers loved them and were quick converts, while other reactions ranged from disinterest to outright hatred -- much of it shared on blogs or in Facebook groups.
An internal study by Big Y found delays in its self-service lines caused by customer confusion over coupons, payments and other problems; intentional and accidental theft, including misidentifying produce and baked goods as less-expensive varieties; and other problems that helped guide its decision to bag the self-serve lanes."
Here is what I say about in class (which we covered this week):
"Structural unemployment: unemployment caused by a mismatch between the skills of job seekers and the requirements of available jobs.
One example of this is when you are replaced by a machine. We don’t have as many bank tellers any more because people use ATMs. Another example is when there is a fall in demand for your product, so you get laid off, like with typewrites since people now use computers. A third example is geographical, when the jobs are not in your region of the country."

Will There Be A Pumpkin Shortage This Year?
See The Great Pumpkin Shortage: Stormy Summer Limits Supply In Northeast By MEGAN GIBSON of Time.com. Here is an excerpt:
Then sellers will reduce supply in anticipation of the higher price, further speeding up the price increase. My guess is that sellers try to project consumer behavior on this and will raise the price based on this.
But if the price actually doubles, then that would eliminate the shortage. We have the supply line moving to the left, raising the price and lowering the quantity bought and sold. Yes, fewer people will get pumpkins this time of year, but there is no shortage.
"As much as we hate to admit we need pumpkins - NewsFeed answers to no vegetable - this time of year we really do. Unfortunately for those of you in the Northeast, pumpkins might not be so readily available for your Halloweening needs.Of course, if everyone tries to "move quickly," that could make the price rise sooner. This relates to one of the shift factors of demand, expectation of future price. If buyers expect higher prices in the near future, demand today increases which will cause the price to rise.
Thanks to Tropical Storm Irene and an especially stormy summer, there are severe reported shortages in pumpkin crops across the region as bad weather conditions have led to higher numbers of rotten vegetables. Which means that pumpkin seekers could be paying double for their Jack-o'-lantern canvases in some places and, in others, they could be out of luck entirely.
What's a Halloween lover to do? Now just because you didn't see this shortage coming, doesn't mean there's no hope for you. Now that you know, however, your first course of action should be to move quickly. David Dumaresq of Farmer Dave's told CBS that you should "[b]uy your pumpkins soon for the best availability because there's not going to be too many around this year.""
Then sellers will reduce supply in anticipation of the higher price, further speeding up the price increase. My guess is that sellers try to project consumer behavior on this and will raise the price based on this.
But if the price actually doubles, then that would eliminate the shortage. We have the supply line moving to the left, raising the price and lowering the quantity bought and sold. Yes, fewer people will get pumpkins this time of year, but there is no shortage.

Josh Hamilton’s grand slam causes a flooring and countertop shortage
Click here to read the story. Or just read it here:
"ARLINGTON, Texas (AP)—A Dallas carpet company has had trouble with its website much of the day, thanks to Texas Rangers slugger Josh Hamilton(notes).
The Rangers beat Cleveland on Wednesday night, helped by Hamilton’s grand slam. It just so happened that CC Carpet was offering free flooring and countertops to customers in September if the Rangers outfielder hit a grand slam.
Hamilton did his part and the company has to pay up. Not long after the hit, the company’s website crashed and it’s been spotty Thursday.
CC Carpet president Steve Fitzgerald says the promotion will cost his company about $500,000 but it’s covered by insurance."

Could Those Hours Online Be Making Kids Nicer?
What would Adam Smith say, especially the one from Wednesday's post? Click here to read the Wall Street Journal article about this. Maybe Facebook and Twitter have positive externalities. Excerpts:
"Time spent online may be helping people learn to be more empathetic and make more friends in real life.
A growing body of research indicates the widespread use of texting, emailing or posting on social-media sites has social benefits."
"...digital communication can lead to more or better friendships online and off, greater honesty, faster intimacy in relationships and an increased sense of belonging, in addition to practical social benefits like an expanded circle for networking."
"...technology appears to enhance real-world relationships..."
"People use digital communication primarily to interact with people they are closest to offline, not with strangers. The communication tightens the bonds between them..."
"... technology-driven communication may be particularly helpful for people who are shy or anxious in social settings."
"Anxious students reported greater shyness and discomfort than non-anxious students in face-to-face groups. In the chat room, however, they said they felt significantly less shy, more comfortable and better accepted by their peers."
"Socially anxious participants were more likely to make decisions and lead the group when they were in the chat room than when face-to-face with others."
"Frequent communication online could serve as practice for in-person social interactions..."
"...empathy could indeed be recognized and communicated through written, online communication."
"Digital communication also appears to bolster individuals' sense of community and group identity..."
"Students reporting low self esteem who actively used Facebook were more likely to say they felt a part of the Michigan State community than low self-esteem individuals who didn't use Facebook as intensely..."

Adam Smith vs. Bart Simpson
In March of 2010, I attended a lecture by Paul Zak, a neuro-economist from Claremont Graduate University, at the Mind Science Foundation. This week in my micro class I talked about utility and how consumers behave. neuroeconomics is all about looking inside our brains to see what makes us tick.
Zak has studied how our behaviors are affected by the presence in our brains of a chemical called oxytocin, which can affect how generous we are. The more oxytocin you have have, the more generous and empathic (or sympathetic) you are. So he calls oxytocin "the moral molecule." It helps us identify with others and understand their feelings and situatons. Oxytocin can also increase when people trust you or are generous to you.
What does this have to do with Adam Smith? He wrote a book called The Theory of Moral Sentiments. One point he made there was that we are able to sympathize with other people by trying imagine what they are going through. This is directly related to oxytocin. In September 2009 I had a post on this called Science Proves That Adam Smith Was Right Over 200 Years Ago (sort of). That will provide you with more details.
Where does Bart Simpson come in? Professor Zak showed a video clip from the "The Simpsons" that illustrated sympathy, a concept that Adam Smith wrote about in the above mentioned book. To watch a lecture by professor Zak (very similar to the one he did here in San Antonio), go to The Moral Molecule. The Bart Simpson clip starts at the 7:40 mark. Bart's mom tells him to look at his sister and try to feel what she feels. Exactly the kind of thing Adam Smith talked about.
Oxytocin also facilitates trust. Economies need trust because not everything can be put into a law, a contract or be monitored. Your boss can't watch you every second to make sure you don't slack off on the job. We trust banks and our pension funds not to take the money and blow it all in Vegas. We trust our government officials not to accept bribes. Yes, we have rules and regulations against these things. But if we had to have a rule for everything and if everyone was being watched constantly, it would be too costly to our economy. Trust helps quite a bit.
Here are two articles about professor Zak's lecture from the San Antonio Express-News:

Some Reasons Why Firms Are Not Hiring
See What's Wrong With America's Job Engine?: Wary Companies Rely on Temps, Part-Timers, Hire Overseas by DAVID WESSEL, WSJ 7-27-11. Excerpts:
"That's largely because the economy is growing much too slowly to absorb the available work force, and industries that usually hire early in a recovery—construction and small businesses—were crippled by the credit bust.
Then there's the confidence factor. If employers were sure they could sell more, they would hire more. If they were less uncertain about everything from the durability of the recovery to the details of regulation, they would be more inclined to step up their hiring."
"Something else is going on, too, a phenomenon that predates the recession and has persisted through it: Changes in the way the job market works and how employers view labor.
Executives call it "structural cost reduction" or "flexibility." Northwestern University economist Robert Gordon calls it the rise of "the disposable worker," shorthand for a push by businesses to cut labor costs wherever they can, to an almost unprecedented degree.
Looking back at the percentage of Americans with jobs in the 1990s (rising) and the 2000s (falling), Princeton University economist Alan Krueger estimates that 70% of today's job shortage is simply cyclical, the result of a disappointing recovery from a deep recession. But he attributes 30% to changes in the job market that began a decade or more ago."
"In the most recent recession and the previous two—in 1990-91 and 2001—employers were quicker to lay off workers and cut their hours than in previous downturns. Many also were slower to rehire."
"Between the end of 2007 (when American employment peaked) and the end of 2009 (when it touched bottom), the U.S. economy's output of goods and services fell by 4.5%, but the number of workers fell by a much sharper 8.3%."
"At the worst of the 1980-82 recession, 1 in 5 of the unemployed were "temporary layoffs." In the recent recession, the proportion of temporary layoffs never exceeded 1 in 10. In part that's because fewer Americans work in factories, where production can be stopped and restarted; if a restaurant doesn't have enough customers, it goes out of business.
"When layoffs are temporary, subsequent recalls can take place quickly," say economists Erica Groshen and Simon Potter of the Federal Reserve Bank of New York. When layoffs are permanent, job recovery is slower, they say. If the employer wants to hire, there's the time-consuming chore of sifting through applications.
Corporate employers, their eyes firmly fixed on stock prices and the bottom line, prize flexibility over stability more than ever. The recession showed them they could do more with fewer workers than many of them previously realized."
"58% of employers expect to have more part-time, temporary or contract workers over the next five years and 21.5% more "outsourced or offshored" workers.
"Technology," McKinsey says, "makes it possible for companies to manage labor as a variable input. Using new resource-scheduling systems, they can staff workers only when needed—for a full day or a few hours."
Temporary-help agencies are playing an ever-larger role"
"Workers, in short, now can be hired "just in time.""
"Because they can hire temps almost instantly, there's little need to hire in anticipation of a pickup in business."
"When they do hire, big U.S.-based multinational companies are more able and more willing to hire overseas, both because wages are often cheaper there and because that's where the customers are."
"some employers insist they can't find workers with the skills they need at wages they can afford."
"difficulty in hiring workers "with specialized technical skills, particularly in the health-care and technology sectors."
But workers without college degrees find well-paying jobs scarce."

Links To Differing Opions On President Obama's New Economic Policy Proposals
First, here is a link from the White House about the proposal:
Fact Sheet: The American Jobs Act.
Here is a quick summary from Megan McArdle (who writes for The Atlantic Monthly):
Tax cuts: $250 billion
•Payroll tax rebate on first $5 million in payroll, which the president says will reach 98% of American companies, plus complete rebate for new hires or raises
•Extending payroll tax cut
•Extending 100% expensing of business investment
•(A bunch of regulatory streamlining that is likely to have little effect and is bizarrely classed as a tax cut)
•Tax credits for hiring unemployed veterans, particularly those with service-connected disabilities
•$4,000 per worker for hiring workers who have been unemployed for more than six months
Infrastructure: about $100 billion
•$50 billion for new infrastructure projects
•$10 billion for an infrastructure bank
•$15 billion to rehab vacant and foreclosed homes/businesses
•Some undisclosed sum for getting high speed wireless to "98% of American"
•$25 million to rehab schools
Direct assistance: About $100 billion (?)
•Continuing the extension of unemployment benefits
•Various retraining/wage support ideas that are supposed to help the structurally displaced to transition into new careers.
•$35 billion for preserving/hiring teachers, cops and firefighters
•Federal assistance in refinancing to current mortgage rates
Now links to the various opinions:

Your Co-Workers Might Be Killing You
Interesting article by Jonah Lehrer, from The Wall Street Journal, 8-20-11. Click here to read it. Here are some excerpts:
"...jobs don't just take a physical toll—they also exact a mental price. When people experience chronic levels of stress—and this is precisely what happens when our workplace is unpleasant or demanding—their risk of suffering from a long list of ailments, such as Alzheimer's, heart disease, depression and even the common cold, is dramatically increased."
"..."psychosocial" factors, such as work-related stress, are the single most important variable in determining the length of a life."
"...the factor most closely linked to health was the support of co-workers: Less-kind colleagues were associated with a higher risk of dying."
"...middle-age workers with little or no "peer social support" in the workplace were 2.4 times more likely to die during the study."
"...worst kind of workplace stress occurs when people have little say over their day. These employees can't choose their own projects or even decide which tasks to focus on first. Instead, they must always follow the orders of someone else."
"...a lack of control at the office was deadly—but only for men. While male workers consistently fared better when they had some autonomy, female workers actually fared worse. Their risk of mortality was increased when they were put in positions with more control."

Do looks matter?
See Ugly? You May Have a Case by DANIEL S. HAMERMESH, professor of economics at the University of Texas, Austin. From the 8-28-11 New York Times. Excerpts:
"...being attractive also helps you earn more money, find a higher-earning spouse (and one who looks better, too!) and get better deals on mortgages."
"...one study showed that an American worker who was among the bottom one-seventh in looks, as assessed by randomly chosen observers, earned 10 to 15 percent less per year than a similar worker whose looks were assessed in the top one-third — a lifetime difference, in a typical case, of about $230,000."
"Most of us, regardless of our professed attitudes, prefer as customers to buy from better-looking salespeople, as jurors to listen to better-looking attorneys, as voters to be led by better-looking politicians, as students to learn from better-looking professors. This is not a matter of evil employers’ refusing to hire the ugly: in our roles as workers, customers and potential lovers we are all responsible for these effects."
"You might argue that people can’t be classified by their looks — that beauty is in the eye of the beholder. That aphorism is correct in one sense: if asked who is the most beautiful person in a group of beautiful people, you and I might well have different answers. But when it comes to differentiating classes of attractiveness, we all view beauty similarly: someone whom you consider good-looking will be viewed similarly by most others; someone you consider ugly will be viewed as ugly by most others. In one study, more than half of a group of people were assessed identically by each of two observers using a five-point scale; and very few assessments differed by more than one point."

Small Changes In Growth Rates Add Up Over Time
In my macro courses we read a chapter in the book "The Economics of Macroissues." The chapter discussed how nations with common law systems, where property rights are better protected than in nations with civil law systems, have higher growth rates. I pointed out to my classes that even a small difference in growth rates ends up causing a very big difference in per capita incomes due to the annual compounding effect.
In early 2010, Paul Krugman mentioned that the per capita GDP since 1980 has grown 1.95% in the US and 1.83% in the EU. But we should also remember that small differences in growth rates compound over time. If per capita income was 20,000 in both the US and EU 29 years ago, the per capita income (or GDP) now would be 35,015 in the US and 33,839 in the EU, a difference of $1,176. Maybe not a big difference. But after 100 years the US income level would be 12% higher. After 200 years it would be 26% higher.
The table below shows how much per capita income would be at various rates after 100 and 200 years. Assume we start with a per capita income of $1,000. If we grow 2.0% per year, after 100 years it will be $7,245. At 2.1% per year, it would be $7,791 or about $700 more. That is how much that little .1% matters. The difference over 200 years is about $11,000. After 100 years at 2.5% per year, per capita income would be $11,814. That is $4,000 more than the 2.0% rate. Small differences in growth rates add up to big differences over time.

William Breit, Trinity University economics professor, has passed away
I only met him once or twice. But alot of people knew about him and many bloggers have expressed their condolences. He began his academic career as a student at San Antonio College in 1950 after graduating from Jefferson High School. He went on to write many books and was well known in the economics profession. Here are some of the blogs that marked his passing:

There really is a marriage market in many countries
See Supply, Demand and Marriage by Robert Frank, New York Times, 8-6-11. Excerpts:
"IN some cultures, romance isn’t nearly as important as cash when it comes to choosing a marriage partner. And even when money plays no explicit role in selecting a mate, courtship customs are governed by the venerable economic model of supply and demand.
Under the dowry system in India, for example, parents of older brides would typically pay more to prospective grooms. Men with better jobs would receive larger payments, too.
In short, there really is a marriage market in many countries around the world, and economic principles apply to it. In markets with a preponderance of women seeking partners, the terms of trade shift in favor of men. If more men are seeking partners, the reverse is true. Two cases in point are the baby-boom generation in the United States and the current youth cohort in China."
"Before the 1960s, cultural norms encouraged celibacy before marriage. The breakdown of those norms has been widely attributed to the introduction of oral contraception, which gave women an unintrusive way to protect themselves against an unwanted pregnancy. The pill no doubt played a role — perhaps a very big one — but skeptics object that effective alternative forms of contraception had long since been available.
The supply-and-demand model bolsters the skeptics’ concerns. Biologists describe a fundamental asymmetry in the sexual strategies favored by males and females in vertebrate species. Males, whose sex cells are cheap to produce, tend to favor more transient sexual relationships, whereas females, for whom pregnancy and birth are far more costly, tend to favor greater commitment. The sexual revolution, which bent cultural norms toward male preferences, may thus be partly explained by the excess demand for grooms in the 1960s.
An imbalance in the opposite direction characterizes the contemporary marriage market in China. The Chinese government’s one-child policy, combined with a cultural preference for sons and technologies that permit selective abortion, have helped to create a large sex-ratio imbalance among young Chinese. For every 100 women in that group, there are now more than 120 men.
According to market models, the terms of trade in the Chinese marriage market should have shifted sharply in favor of women. And evidence suggests that young Chinese women and their families have in fact become much more selective in recent years.
They appear, for example, to focus more critically on the earnings potential of prospective mates. Because house size is often assumed to be a reliable signal of wealth, a family can enhance its son’s marriage prospects by spending a larger fraction of its income on housing. (Other families can follow the same strategy, of course, but when all families do so, the resulting homes are still reliable indicators of relative wealth.) Such a shift appears to have occurred."
"...families with sons built houses that were significantly larger than those built by families with daughters, even after controlling for family income and other factors. They also generally found that the higher a city’s male-to-female ratio, the bigger the average house size of families that have sons.
Mr. Wei reports that many families with sons have begun to add a phantom third story to their homes, one that looks normal from the outside but whose interior space remains completely unfinished."
There is "...evidence that men are more likely to make risky financial investments in cities with higher male-to-female ratios. Their specific finding was that significantly more local businesses are started in such cities."

Do Married Baseball Players Get Paid More Than Single Baseball Players?
There is a research paper by two economists Productivity, Wages, and Marriage: The Case of Major League Baseball. Here is the abstract or summary:
It seems like they do a good job using ceteris paribus conditions (but I have not read the whole paper). They seem to be holding player quality or performance constant and they say that the control for selection. There is always the possibility that women prefer to marry men who make more money (in general married men make more but that does not mean that getting married caused their salary to go up). Somewhere they say that the 20% difference only applies to the top 1/3 of players.

Married MLB players earn more than single MLB players of the same quality?
"Using a sample of professional baseball players from 1871 - 2007, this paper aims at analyzing a longstanding empirical observation that married men earn significantly more than their single counterparts holding all else equal. There are numerous conflicting explanations, some of which reflect subtle sample selection problems (that is, men who tend to be successful in the workplace or have high potential wage growth also tend to be successful in attracting a spouse) and some of which are causal (that is, marriage does indeed increase productivity for men). Baseball is a unique case study because it has a long history of statistics collection and numerous direct measurements of productivity. Our results show that the marriage premium also holds for baseball players, where married players earn up to 20% more than those who are not married, even after controlling for selection. The results are generally robust only for players in the top third of the ability distribution and post 1975 when changes in the rules that govern wage contracts allowed for players to be valued closer to their true market price. Nonetheless, there do not appear to be clear differences in productivity between married and nonmarried players. We discuss possible reasons why employers may discriminate in favor of married men."
It seems like they do a good job using ceteris paribus conditions (but I have not read the whole paper). They seem to be holding player quality or performance constant and they say that the control for selection. There is always the possibility that women prefer to marry men who make more money (in general married men make more but that does not mean that getting married caused their salary to go up). Somewhere they say that the 20% difference only applies to the top 1/3 of players.

Degrees ranking highest in terms of employment
In case any of my students are interested knowing more about the job market, see Degrees That Employers Want. Here are the top six they list:
#1 - Health Care Degree
#2 - Business Administration Degree
#3 - Computer Science Degree
#4 - Accounting/Finance Degree
#5 - Engineering Degree
#6 - Marketing Degree
Of course, if many students see this and go into these areas, they won't pay as much or be as secure if their markets get flooded.

Keynes vs. Hayek
Probably most people have seen this video or know about it. We watched it in my macro classes this week. There are actually two videos. Here they are in order. My class saw the second one. Then there is a link to readings over these issues.
Fear the Boom and Bust
Fight of the Century: Keynes vs. Hayek Round Two
Get the Story Behind the Fight of the Century
If you want to tell Russ Roberts, the economics professor who made the video, what you think, go to Fight of the Century in the classroom

Was 1800 (approximately) A Pivotal Year In Human History? Robert Fogel, Francis Fukuyama, And Deirdre McCloskey All Seem To Think So
Robert Fogel is a Nobel Prize Winning Economist. Here is something he said recently:
See Technology Advances; Humans Supersize.
Francis Fukuyama, author of the famous book The End of History and the Last Man, has a new book out. Here is an excerpt from a review of that book:
See From Dynasty to Democracy: Nations did not find stability, or sustained prosperity, until they became accountable to their citizens.
Deirdre McCloskey is a highly respected economic historian whose latest book is Bourgeois Dignity: Why Economics Can't Explain the Modern World. Here are some quotes from her:

"Technology rescued humankind from centuries of physical maladies and malnutrition, Mr. Fogel argues. Before the 19th century (1800), most people were caught in an endless cycle of subsistence farming."
See Technology Advances; Humans Supersize.
Francis Fukuyama, author of the famous book The End of History and the Last Man, has a new book out. Here is an excerpt from a review of that book:
"But it is true that Mr. Fukuyama tracks a quest for "order" that often falls short of its goal until a decisive threshold is reached around 1800.
By then the Industrial Revolution—even at its earliest stages—had unleashed the forces of production in ways hitherto unimaginable, allowing for abundance rather than scarcity, not least in the production of food. But the threshold proved to be more than a matter of escaping "the Malthusian trap" of hunger and overpopulation. In the years surrounding the French Revolution, Mr. Fukuyama believes, politics began to shape itself—at last—into an orderly and sustainable form.
Obviously, political order had been achieved before then, but in a fitful and incomplete way. In Mr. Fukuyama's view, a durable political order can arise, and societies can fully thrive, only when a state is formed, when the state itself operates according to a rule of law, and when the state becomes accountable—that is, when it must answer to its citizens. Until the threshold point around 1800, he says, all three properties rarely existed together."
See From Dynasty to Democracy: Nations did not find stability, or sustained prosperity, until they became accountable to their citizens.
Deirdre McCloskey is a highly respected economic historian whose latest book is Bourgeois Dignity: Why Economics Can't Explain the Modern World. Here are some quotes from her:
"Modern economic growth—that stunning increase from $3 a day in 1800 worldwide to now upwards of $130 a day in the richest countries, and anyway $30 as a worldwide average—can’t be accounted for in the usual and materialist ways. It wasn’t trade, investment, exploitation, imperialism, education, legal changes, genes, science. It was innovation, such as cheap steel and the modern university, supported by an entirely new attitude towards the middle class, emerging from Holland around 1600. (It has parallels in classical music and mathematics and politics, in all of which the Europeans burst out, 1600-1800.)
Economics of the usual sort, whether Samuelsonian or Marxist, can’t get at why Europeans and then the rest of us started around 1800 to become insanely innovative. A new dignity for innovation and its market applications can: that’s a sociological change, supporting sensible economic policies.
What you can learn from the history is that stasis reigned until we discovered dignity and liberty for ordinary people, and in particular for the disturbing, irritating class of entrepreneurs."
