Merchants and Shoppers Sour on Daily Deal Sites

By STEPHANIE CLIFFORD and CLAIRE CAIN MILLER

As their e-mail in-boxes filled with daily deal offers from Web sites like Groupon, Lea Pische and Edwin Hermawan, a pizzeria waitress and a former lawyer living on the Lower East Side, finally decided to buy one: a discounted Skillshare class on how to start a business.

Their business plan? It was a service that would unsubscribe people from all those daily deal e-mails.

Three months after its introduction, UnsubscribeDeals.com has 7,800 unsubscribers, a number that nearly doubled in the last month. Ms. Pische and Mr. Hermawan tapped into deal fatigue, a malady that has been afflicting the small businesses that offer daily deals and is now hitting consumers too.

Daily deal services — like Groupon, LivingSocial and Google Offers — took off because they seemed to offer something for everyone: small businesses got a novel way to bring new customers in the door, shoppers got a discount and the deal providers got a large cut of every sale.

But signs of deal fatigue are everywhere, raising questions about whether Groupon and its competitors can continue their hyper-growth.

In the last six months of 2011, 798 daily deal sites shut down, according to Daily Deal Media, which researches the industry.

When Groupon reported its second-quarter results this week, it said that active customers — defined as people who purchased a Groupon deal in the last year — grew just 3 percent, a significant slowdown from previous quarter-to-quarter customer growth rates. While traffic to Groupon was higher at the beginning of 2012 than last year, it was down almost 10 percent in May and June from the same months in 2011, according to comScore.

Shares of Groupon have fallen 82 percent since it went public in November, and the company is now worth just $3 billion, half of what Google offered to buy it for in 2010.

Gilt City, a daily deal service owned by Gilt Groupe, laid off employees and closed offices in six cities earlier this year. Google Offers, whose membership has plateaued in some cities, has had to team with 35 other deal providers to supplement its own selection and help other companies reach customers. Facebook and Yelp were quick to jump on the fad, but backed off last year. Groupon is searching for alternative ways to make money, like buying movie tickets, watches and other goods and selling them to shoppers.

“Many of the other competitors have retreated or scaled down ambitions,” said Jordan Rohan, an analyst with Stifel Nicolaus. “There are no real barriers to entry, but there are fairly significant barriers to success.”

One of those barriers is keeping merchants happy. Though small businesses were excited at first about a new way to attract customers in a post-Yellow Pages world, many soon soured on the daily deals. Customers who bought deals overwhelmed the businesses, spent the bare minimum and never returned.

The scene on a three-block stretch of Mississippi Avenue in Portland, Ore., is a snapshot of what is happening nationally, as merchants grow increasingly wary of daily deal services even as more daily deal salespeople try to court them.

Muddy’s Coffeehouse, which serves coffee and granola in a purple-trimmed Victorian home, offered $24 of food and coffee for $12. It paid Groupon half of that. Muddy’s succeeded in drawing crowds — but ended up losing money.

“I pretty much had to take a loan out to cover the loss, or we would have probably had to close,” the owner, Dyer Price, said. “They don’t warn you that you’re going to get hit really hard and that you have to be prepared. We will never, ever do it again.”

A few doors down, Mississippi Studios & Bar Bar, a former Baptist church that became a live music club and burger and cocktail restaurant, offered a Groupon deal but said it slowed down the bartender, who had to complete paperwork for each coupon, and brought in customers who did not return.

“It was a huge boondoggle for us, and we were counting down the days until it was over,” said Kevin Cradock, co-owner of Mississippi Studios. He said he had a better solution for local advertising. “We still do the old-school thing,” he said. “We print these posters and hire kids on bikes to put the posters up.”

He also tried Google Offers, whose deal was easier to process because Google sent an Android phone to scan coupons, but it did not attract repeat customers, either.

The story was the same elsewhere. Kevin Stecko, founder of 80sTees.com, offered a Groupon deal for $20 off a $40 order, of which $10 would go to Groupon. Initially, the results looked good: 971 coupons were sold, and almost all of the customers were new.

But Mr. Stecko said he lost $2.96 per order on average, and only nine of the customers who used the Groupon deal had bought something else from the site since then. (He made some money, though, he said, because 14 percent of people who bought coupons did not redeem them.)

“It devalues your product,” said Rafi Mohammed, a pricing consultant. “You get people who come in who are very price-sensitive, who aren’t going to come back and pay full price.”

Groupon has added tools to help merchants with some of their most common complaints, like a scheduler so they can avoid an overwhelming rush of customers. The company said that in the last two quarters, half of its offers were from businesses that had previously used Groupon.

But that might not matter if shoppers continue to tire on daily deals.

Tamara Koedoot, 47, a real estate agent in Portland, has spent about $100 on four deals a month for several years. But lately, it has been testing her patience, partly because she said businesses discriminated against her for using coupons.

“As soon as they find out you have a Groupon, they don’t even want to work with you any longer, so that’s a turnoff,” she said.

Ms. Koedoot has cut back on buying deals because she has lost money when coupons she bought, like one for a Spanish language course, expired, or when she could not get restaurant reservations before the expiration date.

“My thoughts have definitely changed, and I think my friends are kind of feeling the same way,” she said. “We’ve got to quit buying so many of them because it’s like, ‘We’ve got this Groupon, we have to go now.’ ”

UnsubscribeDeals.com has become a support group for shoppers who are fed up with deals.

Some commenters take issue with the frequency of the e-mails, while others complain about the quality of the offers. “I once got a Groupon for teeth whitening,” one person wrote. “I went to the office and the receptionist gave me some bleach and told me to do it at home. She said it would be extra if I wanted the dentist to do it.”

When the Network Effect Goes Into Reverse

By JAMES B. STEWART

With battered Facebook shares closing Friday at just over half their offering price in May, no one’s talking anymore about a social media “bubble.”

Just a year ago, social media seemed the next big thing. With dizzying user growth at Twitter, Zynga and especially Facebook, investors were euphoric about Internet sites that connected people with shared interests and experiences, seemingly the perfect media for targeted advertising.

The professional networking and job search site LinkedIn was first to test the public’s appetite when it went public in May 2011. Its shares more than doubled to close at $94.25 after trading as high as $122.70 that first day.

Early investors were understandably giddy, but others, like the former Treasury secretary Lawrence H. Summers, sounded a cautionary note. “Who could have imagined that the concern with respect to any American financial asset, just two years after the crisis, would be a bubble?” Mr. Summers asked at the time. Over the last year, Internet companies like Groupon, Zynga and Yelp made their public debuts. Facebook followed in May at $38 a share, instantly giving the newly minted public company a valuation of nearly $105 billion. Since then, euphoria has given way to mounting anxiety.

Facebook hasn’t closed above $38 since. The initial offering was widely deemed a debacle both for trading glitches and for the need for underwriters to prop up the stock.

The shares’ subsequent decline accelerated after the company’s first earnings report as a public company late last month dashed investors’ hopes for torrid growth.

This week was the end of the lockup period, which barred insiders from immediately selling their shares, and Facebook shares hit a new low, slumping to $19.05.

Other Internet companies have fared even worse.

Like Facebook, the Internet discount coupon site Groupon increased its offering price and number of shares just before its public debut last November. After rejecting a $6 billion takeover bid from Google in December 2010, Groupon shares closed at $26.11 on its first day of trading, up from its $20 offering price, giving it a market value of $13 billion.

It has been pretty much downhill ever since. On Friday, Groupon shares fell to $4.75, a decline of more than 75 percent from its offering price, giving it a market capitalization of just over $3 billion, barely half what Google offered.

Zynga, a company that makes online social games, went public in December at $10 and dropped 5 percent its first day. Although it traded above $14 a share as recently as March, it ended the week at $3, down 70 percent.

Shares of even the best-performing social media sites have stagnated. Yelp’s shares, which jumped 64 percent on their first day of trading in March to close at $23, were below $22 this week. And LinkedIn, considered by many to be the gold standard for social media concerns, never again hit its opening peak, and ended the week below $102.

Twitter and LivingSocial have put the brakes on going public; the companies have recently said they’re in no rush. That’s hardly surprising.

What went wrong?

Every company has its own story, but the euphoria over social media companies as a group was rooted in what economists call the network effect. The more users a site attracts, the more others will want to use it, which creates a natural monopoly and a magnet for advertisers.

Facebook has been a classic example. If your friends, colleagues or classmates are all on it, you’re all but compelled to join. But evidence that the network effect is working requires rapid growth in users and revenue, especially during the early stages of a company’s public life. So far, social media has failed to deliver the kind of growth that would bolster investor optimism, let alone euphoria.

The network effect is a double-edged sword, Ken Sena, a consumer Internet analyst at Evercore, told me this week.

“The network effect allowed these companies to grow so fast, but the decline can be just as ferocious,” Mr. Sena said. “If any of them misstep with users, they can leave, and the network effect goes into reverse.” The textbook case is Myspace, once the most visited social networking site, that is now a shadow of its former self.

This week’s Groupon earnings illustrated the problem for social media companies. In theory, Groupon should benefit from the network effect. The more users it attracts, the more merchants will want to offer coupons through Groupon, and vice versa. And on the face of it, the earnings report looked good. Groupon earned a profit of $28.4 million for the quarter, above analysts’ expectations, reversing a loss a year ago. Groupon’s boyish-looking chief executive, Andrew Mason, called it a “solid quarter.”

But growth, not profit, is what matters at the early stage in the life of a networked Internet company. Groupon said revenue grew 45 percent over the same quarter last year. But it counts payments that it passes on to merchants as part of its revenue. When that part of revenue was excluded, revenue grew just 30 percent. And compared with the previous quarter, revenue grew just 1.6 percent.

Growth in its core coupon business dropped 7 percent from a year earlier, according to Mr. Sena. (Other revenue came from Groupon’s Goods business, a lower-margin operation that competes with Amazon.) Groupon projected that revenue growth in the next quarter would be just 2.9 percent higher.

Such slow growth was a jolt for investors, and Wall Street’s judgment was swift, with Groupon shares down 27 percent on Tuesday, the day after the earnings were announced.

A positive network effect is also supposed to exclude competitors, but Groupon has long suffered from the perception that it’s vulnerable to competition.

The online auction market is dominated by eBay, for example, but many merchants offer coupons. Amazon bought a 29 percent interest in a rival coupon site, LivingSocial, and Google introduced its own offerings after being rebuffed by Groupon.

There are now so many that sites have sprung up to help consumers sort them out. One of these, localdealsites.com, listed 167 sites when I consulted it this week, though many are much smaller in scope than Groupon.

LivingSocial has run into its own concerns. Although the company is still private, Amazon has to release some financial details because of its large ownership stake. Last month, Amazon said that it was writing off $28 million in LivingSocial’s book value and that LivingSocial lost $93 million in the quarter that ended June 30, even though revenue more than doubled.

Facebook faced a similar problem rooted in high expectations. In its first earnings report, it reported revenue growth of 32 percent over a year earlier and nearly one billion users worldwide. But even though 32 percent topped analysts’ estimates, it was not the triple-digit growth many investors were hoping for.

And although the number of monthly active users hit 955 million, that was just 29 percent higher than a year before. Some analysts used the dreaded word mature to describe Facebook’s penetration in North America, and others noted that user growth was slowing.

A major challenge, as well as an opportunity, for Facebook is the migration of users from personal computers to mobile devices. Facebook said 543 million users looked at the site on mobile devices during the last quarter, and its chief executive and founder, Mark Zuckerberg, acknowledged that the shift “is incredibly important.” But Facebook hasn’t mastered how to convert customer use into mobile ad revenue.

“Migration to mobile is a big problem,” Mr. Sena said. If ads become obtrusive and alienate users, Facebook could suffer the reverse network effect.

That hasn’t happened yet. New companies, especially in nascent industries like social media, are hard to value. Some may thrive even as others fail. They may yet find ways to turn millions of users into huge profits, as network television did in its heyday.

And although many social media investors have been burned in the short term, it’s not as if they’ve given up hope.

Social media companies still trade at lofty valuations: Even after recent declines, LinkedIn’s price-to-earnings ratio is a stratospheric 852; Facebook’s is a much lower but still lofty 69. By comparison, the market average for companies in the Standard & Poor’s 500-stock index is about 16.

Since they haven’t earned a full year’s profit, Groupon and Zynga don’t even have price-to-earnings ratios.

“The valuations are still high,” Mr. Sena said. “There are few positive catalysts likely near term, and a lot of people think you’ll be able to buy these stocks cheaper.”

Even for Cashiers, College Pays Off

By DAVID LEONHARDT

ALMOST a century ago, the United States decided to make high school nearly universal. Around the same time, much of Europe decided that universal high school was a waste. Not everybody, European intellectuals argued, should go to high school.

It’s clear who made the right decision. The educated American masses helped create the American century, as the economists Claudia Goldin and Lawrence Katz have written. The new ranks of high school graduates made factories more efficient and new industries possible.

Today, we are having an updated version of the same debate. Television, newspapers and blogs are filled with the case against college for the masses: It saddles students with debt; it does not guarantee a good job; it isn’t necessary for many jobs. Not everybody, the skeptics say, should go to college.

The argument has the lure of counter intuition and does have grains of truth. Too many teenagers aren’t ready to do college-level work. Ultimately, though, the case against mass education is no better than it was a century ago.

The evidence is overwhelming that college is a better investment for most graduates than in the past. A new study even shows that a bachelor’s degree pays off for jobs that don’t require one: secretaries, plumbers and cashiers. And, beyond money, education seems to make people happier and healthier.

“Sending more young Americans to college is not a panacea,” says David Autor, an M.I.T. economist who studies the labor market. “Not sending them to college would be a disaster.”

The most unfortunate part of the case against college is that it encourages children, parents and schools to aim low. For those families on the fence — often deciding whether a student will be the first to attend — the skepticism becomes one more reason to stop at high school. Only about 33 percent of young adults get a four-year degree today, while another 10 percent receive a two-year degree.

So it’s important to dissect the anti-college argument, piece by piece. It obviously starts with money. Tuition numbers can be eye-popping, and student debt has increased significantly. But there are two main reasons college costs aren’t usually a problem for those who graduate.

First, many colleges are not very expensive, once financial aid is taken into account. Average net tuition and fees at public four-year colleges this past year were only about $2,000 (though Congress may soon cut federal financial aid).

Second, the returns from a degree have soared. Three decades ago, full-time workers with a bachelor’s degree made 40 percent more than those with only a high-school diploma. Last year, the gap reached 83 percent. College graduates, though hardly immune from the downturn, are also far less likely to be unemployed than non-graduates.

Skeptics like to point out that the income gap isn’t rising as fast as it once was, especially for college graduates who don’t get an advanced degree. But the gap remains enormous — and bigger than ever. Skipping college because the pace of gains has slowed is akin to skipping your heart medications because the pace of medical improvement isn’t what it used to be.

The Hamilton Project, a research group in Washington, has just finished a comparison of college with other investments. It found that college tuition in recent decades has delivered an inflation-adjusted annual return of more than 15 percent. For stocks, the historical return is 7 percent. For real estate, it’s less than 1 percent.

Another study being released this weekend — by Anthony Carnevale and Stephen J. Rose of Georgetown — breaks down the college premium by occupations and shows that college has big benefits even in many fields where a degree is not crucial.

Construction workers, police officers, plumbers, retail salespeople and secretaries, among others, make significantly more with a degree than without one. Why? Education helps people do higher-skilled work, get jobs with better-paying companies or open their own businesses.

This follows the pattern of the early 20th century, when blue- and white-collar workers alike benefited from having a high-school diploma.

When confronted with such data, skeptics sometimes reply that colleges are mostly a way station for smart people. But that’s not right either. Various natural experiments — like teenagers’ proximity to a campus, which affects whether they enroll — have shown that people do acquire skills in college.

Even a much-quoted recent study casting doubt on college education, by an N.Y.U. sociologist and two other researchers, was not so simple. It found that only 55 percent of freshmen and sophomores made statistically significant progress on an academic test. But the margin of error was large enough that many more may have made progress. Either way, the general skills that colleges teach, like discipline and persistence, may be more important than academics anyway.

None of this means colleges are perfect. Many have abysmal graduation rates. Yet the answer is to improve colleges, not abandon them. Given how much the economy changes, why would a high-school diploma forever satisfy most citizens’ educational needs?

Or think about it this way: People tend to be clear-eyed about this debate in their own lives. For instance, when researchers asked low-income teenagers how much more college graduates made than non-graduates, the teenagers made excellent estimates. And in a national survey, 94 percent of parents said they expected their child to go to college.

Then there are the skeptics themselves, the professors, journalists and others who say college is overrated. They, of course, have degrees and often spend tens of thousands of dollars sending their children to expensive colleges.

I don’t doubt that the skeptics are well meaning. But, in the end, their case against college is an elitist one — for me and not for thee. And that’s rarely good advice.

Carbon Taxes Make Ireland Even Greener

By ELISABETH ROSENTHAL

DUBLIN — Over the last three years, with its economy in tatters, Ireland embraced a novel strategy to help reduce its staggering deficit: charging households and businesses for the environmental damage they cause.

The government imposed taxes on most of the fossil fuels used by homes, offices, vehicles and farms, based on each fuel’s carbon dioxide emissions, a move that immediately drove up prices for oil, natural gas and kerosene. Household trash is weighed at the curb, and residents are billed for anything that is not being recycled.

The Irish now pay purchase taxes on new cars and yearly registration fees that rise steeply in proportion to the vehicle’s emissions.

Environmentally and economically, the new taxes have delivered results. Long one of Europe’s highest per-capita producers of greenhouse gases, with levels nearing those of the United States, Ireland has seen its emissions drop more than 15 percent since 2008.

Although much of that decline can be attributed to a recession, changes in behavior also played a major role, experts say, noting that the country’s emissions dropped 6.7 percent in 2011 even as the economy grew slightly.

“We are not saints like those Scandinavians — we were lapping up fossil fuels, buying bigger cars and homes, very American,” said Eamon Ryan, who was Ireland’s energy minister from 2007 to 2011. “We just set up a price signal that raised significant revenue and changed behavior. Now, we’re smashing through the environmental targets we set for ourselves.”

By contrast, carbon taxes are viewed as politically toxic in the United States. Republican leaders in Congress have pledged to block any proposal for such a tax, and President Obama has not advocated one, although the idea has drawn support from economists of varying ideologies.

Yet when the Irish were faced with new environmental taxes, they quickly shifted to greener fuels and cars and began recycling with fervor. Automakers like Mercedes found ways to make powerful cars with an emissions rating as low as tinier Nissans. With less trash, landfills closed. And as fossil fuels became more costly, renewable energy sources became more competitive, allowing Ireland’s wind power industry to thrive.

Even more significantly, revenue from environmental taxes has played a crucial role in helping Ireland reduce a daunting deficit by several billion euros each year.

The three-year-old carbon tax has raised nearly one billion euros ($1.3 billion) over all, including 400 million euros in 2012. That provided the Irish government with 25 percent of the 1.6 billion euros in new tax revenue it needed to narrow its budget gap this year and avert a rise in income tax rates.

The International Monetary Fund, which oversees the rescue plan, recently suggested that Ireland should “expand the well-designed carbon tax” and its automobile taxes to generate even more money.

Although first proposed by the Green Party, the environmental taxes enjoy the support of all major political parties “because it puts a lot of money on the table,” said Frank Convery, an economist at University College Dublin. The bailout plan for 2013 requires Ireland to embrace a mix of new tax revenues and spending cuts.

Not everyone is happy. The prices of basic commodities like gasoline and heating oil have risen 5 to 10 percent. This is particularly hard on the poor, although the government has provided subsidies for low-income families to better insulate homes, for example. And industries complain that the higher prices have made it harder for them to compete outside Ireland.

“Prices just keep going up, and a lot of people think it’s a scam,” said Imelda Lyons, 45, as she filled her car at a gas station here. “You call it a carbon tax, but what good is being done with it to help the environment?”

The coalition government that enacted the taxes was voted out of office last year. “Just imagine President Obama saying in the debate, ‘I’ve got this great idea, but it’s going to increase your gasoline price,’ ” said Mr. Ryan, who lost his seat in the last election and now leads the Green Party. “People didn’t exactly cheer us on.”

A recent report estimated that a modest carbon tax in the United States that increased incrementally over time could generate about $1.25 trillion in revenue from 2012 to 2022, reducing the 10-year deficit by 50 percent, based on projections from the Congressional Budget Office.

“I think most economists — on the right and the left — think a carbon tax is a good idea,” said Aparna Mathur, a resident scholar at the American Enterprise Institute, a conservative research group that held a daylong seminar on carbon taxes in November. Some economists estimate that a carbon tax could raise $400 billion annually in the United States, she said. But the issue remains a nonstarter in the American political arena. even though Gilbert Metcalf, the Obama administration’s deputy assistant Treasury secretary for environment and energy, long promoted carbon taxes as a Tufts University economist.

The Competitive Enterprise Institute, a conservative advocacy group, has even filed a Freedom of Information suit seeking the release of Treasury Department e-mails containing the word “carbon” to make sure that nothing is in the works. Like many other economists, Dr. Metcalf has argued that carbon taxation is preferable to government regulation or cap-and-trade systems because it sets a straightforward price on greenhouse gas emissions and is relatively hard to evade.

Although carbon taxes in some ways disproportionately affect the poor — who are less able to buy new, more efficient cars, for example — such taxes do heavily penalize the wealthy, who consume far more. As with “sin taxes” on cigarettes, the taxes also alleviate some of the societal costs of pollution.

For several years, the European Commission has encouraged debt-ridden members of the European Union to embrace environmental taxes, saying that its economists have concluded they have “a less detrimental macroeconomic impact” than new income taxes or corporate taxes.

“Europeans don’t like taxes either,” said Connie Hedegaard, the European commissioner for climate action. “But this is good for the environment, and also good for our competitiveness.”

Some of Europe’s strongest economies, like Sweden, Denmark and the Netherlands, have taxed carbon dioxide emissions since the early 1990s, and Japan and Australia have introduced them more recently.

Ireland took the plunge after its economy collapsed in 2008 as a result of loose credit policies that created a real estate bubble; in one year, tax revenues fell 25 percent. With a huge bailout in 2010 by the European Union and the International Monetary Fund, Ireland’s deficit soared to 11.9 percent of its gross domestic product, or over 30 percent with all loans factored in.

The environmental taxes work in concert with austerity measures like reduced welfare payments and higher fees for health care that are expected to save 2.2 billion euros this year. The carbon tax is levied on fossil fuels when they enter the country and is then passed on to consumers at the point of purchase. The automobile sales tax, which ranges from 14 to 36 percent of a car’s market price depending on its emissions, is simply folded into the sticker price.

That sent manufacturers racing to reduce emissions. Automakers like Mercedes and Volvo began making cars with high-efficiency diesel engines that shut off rather than idle when they stop, for example. “For manufacturers it’s all, ‘How low you can get?’ ” said Donal Duggan, a brand manager at an MSL showroom near central Dublin.

Other emissions taxes on cars, including the annual car registration fee, or road tax, are billed directly to customers, potentially adding thousands to annual operating costs. Ninety percent of new car sales last year were in the two lowest-emission tiers.

The taxes on garbage had an immediate impact. In Dun Laoghaire Rathdown County in southeastern Dublin, each home’s “black bin” for garbage headed to the landfill is weighed at pickup to calculate quarterly charges. Green bins for recyclables are emptied free of charge.

“There was a big furor initially, but now everything I throw out, I think, ‘How could I recycle this?’ ” said Tara Brown, a mother of three.

Of course, new environmental taxes bring new pain. Gas, always expensive in Europe, sells here for about $8 a gallon, around 20 percent more than in 2009 because of tightening market supplies and the new tax.

Still, Dr. Convery, the economist, is encouraging the government to raise carbon tax rates for 2013, declaring, “You don’t want to waste a good crisis to do what we should be doing anyway.”
