Price Discrimination 101

YOUmoz | Price Discrimination in Pay Per Click AdvertisingSingle price vs. price discriminating monopolist

The article above gives a great introduction to and several examples of price discrimination among firms with market power. Read the excerpt below then discuss the questions that follow in your comments:

For any product or service, different people have different prices they are willing to pay. If you ever took an Economics course you surely remember the downward sloping demand curve, which is a graphical way of saying that you’ll get more buyers at a low price and fewer buyers at a high price. For a business that cannot price discriminate, this poses a problem. What price to offer?

There might be some consumers willing to pay 80, but twice as many consumers willing to pay 50. If you set the price at 50, you get more revenue, but the people who are willing to pay 80 are happy that your offering was 30 less than they were willing to pay. (Economists call this consumer surplus.) The ideal situation for the business would be to sell to some consumers at 80 and others (the price sensitive ones) at 50. Price discrimination – charging each consumer close to what he or she is willing to pay – increases revenue for the business.

Business strategists are forever trying to figure out ways to price discriminate. For commodities it can be difficult, but some markets are conducive to price discrimination. The classic example is the airline industry. Travelers have different itineraries and routes, and the airlines purposely impose complex pricing rules (e.g. cheaper if you stay over a Saturday) in order to price discriminate. Business travelers typically end up paying more than leisure travelers, and if you fly into or out of a small city you pay more than between large cities. On a flight with 100 passengers, it is possible that everyone paid a different price for the seat – 100 different prices for the same product. Consumers often resent these schemes, but economists love them.

Movie theaters price discriminate by charging lower admission for kids and seniors. Everyone gets the same product – a seat in the theater – but consumers that are more price sensitive pay less. Car dealers discriminate based on how much the customer haggles. Sellers of new products, especially consumer electronics, often price discriminate over time. When the iPhone was first released, consumers willing to pay $600 got to buy it. A couple months later, Apple lowered the price and a larger segment of the public was willing to buy. Apple could have charged $400 from the beginning, but then they would have lost all that revenue from the people willing to pay $600.

Buyers often feel like they are being played for chumps when they learn about price discrimination, but many economists absolutely are crazy about it and wish we had more price discrimination. Businesses are encouraged to make prices secret – create a fog of uncertainty – to get customers to accept prices offered to them. Preston McAfee, an economics professor at the California Institute of Technology, gave a talk about prices. He raves about Dell selling the same computer at different prices based on how the consumer identifies themselves at the website (small business, large business, home users).

Discussion Questions:

  1. Who suffers as a result of price discrimination?
  2. Who benefits from price discrimination and how do they gain?
  3. Is society as a whole better or worse off when a monopolist is able to price discriminate? Explain…

Obama’s stimulus is “the first real test of Keynesian economic policy”

On my way to work this morning I listened to the latest episode of WEBZ Chicago Public Radio’s excellent show This American Life. The theme of this week’s radio show was “the New Boss”. America’s new boss, Barack Obama, has embarked on an ambitious experiment aimed at rescuing the American economy from the most severe recession it has seen since the Great Depression. The economic theory behind Obama’s nearly $1 trillion economic stimulus package was developed by a man we have all heard of in our AP and IB Economics classes, but probably know little about in a historical sense.

The clip from This American Life that I have included below presents a fascinating examination of Keynes’ life and times, and puts his theory into perspective in the history of macroeconomics of the last century. We learn that Keynesian theory has not been truly put to the test, and that Obama’s $830 billion stimulus package is the first real test of Keynesianism.

The clip is a bit long, but it is definitely worth listening to if you are a student or teacher of economics. I know that when I come teo Macroeconomics and Fiscal Policy in my course this spring, I will have my kids listen to and discuss the podcast below. If you’re teaching or learning Macro now, feel free to listen and leave comments about your impressions of the story here.

Another insightful economic discsussion on the Daily Show: how to make fiscal stimulus work

I love this discussion between John Stewart and former director of the National Economics Council Lawrence Lindsey. Stewart pitches his own version of a fiscal stimulus package to the economist, and is surprised when Lindsey agrees with the plan.

I find Lindsey’s suggestion that a stimulus package should include subsidized mortgage rates to home owners fascinating. According to Lindsey, a homeowner with a $200,000 mortgage paying 6% interest on his loan would save $4,000 per year on interest payments if the government accommodated a refinanced rate of 4%. Millions of Americans currently struggling to meet all of their monthly debt obligations while continuing to put food on the table and participate in the consumer economy would benefit from such a scheme. In its current form, Obama’s stimulus package with its $150 billion or so in tax cuts will only put approximately $500 per year for two years into taxpayers’ pockets.

As a homeowner paying a 6% mortgage myself, I can personally say I’d prefer $4,000 in savings on my annual interest payments for the next 23 years (the time remaining on my mortgage) than I would $1000 in cash over the next two years. The mortgage relief plan would result in nearly $100,000 less in interest payments, freeing that income up to be spent on goods and services and contributing to real job creation.

And check out last night’s “moment of Zen”. While Obama’s stimulus package is not quite $1 trillion, it is darn close. Senator Mitch McConnell puts the vast size of the spending bill into perspective for us:

What will become of the Chinese worker?

FT.com / China / Economy & Trade – China’s 20m unemployed raise risk of unrest

The days of full-employment in China appear to be over. For decades under communism, the unemployment rate in China stood at an official level of 0%. Of course, being guaranteed work by a state-owned farm or steel factory didn’t exactly mean that all adult Chinese were “working”, rather that they were “employed”. The “iron rice bowl” of communism disappeared in the decades following Mao’s death during the period of “reform and opening” begun under Deng Xiaoping in 1979.

Upon its opening to the world markets, China embarked on three decades of transition from command to market economic principles, characterized by near double digit growth. The demand for workers in its export sector, centered mostly in the Eastern cities from Shenzhen in the south to Shanghai and Beijing in the north, led to the largest rural to urban migration in human history, as nearly 300 million Chinese left the countryside to seek employment in the country’s massive export sector.

Today, the very engine of China’s growth is sputtering to a halt. The demand for Chinese exports is falling as unemployment rises and incomes fall among its trading partners in Asia and the West. Subsequently, the flow of labor from the countryside to the city has reversed, and for the first time in its long history, China is experiencing urban to rural migration:

More than 20m rural migrant workers in China have lost their jobs and returned home as a result of the global economic crisis according to government figures, raising the spectre of widespread unrest in the authoritarian country.

By the start of the Chinese New Year Spring Festival on 25 January, 15.3 per cent of China’s 130m migrant workers had lost their jobs and returned from manufacturing centres in the south and east of the country to their home villages or towns, according to Chen Xiwen, Director of the Office of Central Rural Work Leading Group, who was quoting a survey from the Ministry of Agriculture.

What does the new demographic trend mean for the world’s most populous nation? Bad news, most likely. The hope of work in the city dwindles with demand for Chinese products, but the agricultural sector, which is the main source of employment in the countryside, shows little promise of employment for the millions returning home.

China’s farming industry has become less, not more, labor intensive over the decades since “reform and opening”. The acquisition of capital has supplanted the need for human labor in rural farming, which is one of the “push factors” that led to the massive internal migrations to cities in the first place. The “pull factor” leading the masses to the coastal metropolises, of course, was employment in a factory producing goods to be exported to foreign markets.

Today China’s workers find themselves in the worst possible situation. There is now a “push factor” of 15-20% unemployment, combined with the high cost of living and the struggle of living as an outside in a big city creating an incentive for Chinese workers to return to their familial homes in the countryside. But once they’ve returned home, they find the same lack of opportunity that caused them to leave in the first place. Urban unemployment may shrink as a result of the reverse migration of workers, but rural unemployment will rise.

For the first time in decades, China is faced with a problem that only a year ago (when growth reached 11%!) most would have thought it unlikely to ever face: catastrophic unemployment. Economic theory would suggest, therefore, that China is facing a situation where falling demand for its output has led to rising unemployment due to the downwardly inflexible nature of workers’ wages. According to the Keynesian AD/AS model above, if demand for Chinese output is not restored on its own (which seems unlikely as the West enters deep recession), then the government must take an active approach to stimulating demand through expansionary fiscal and monetary policies.

Keynesian theory, formulated during the Great Depression of the 1930′s, says that in times of recession, spending in the economy is unlikely to increase on its own due to the huge increases in unemployment and corresponding lack in consumer and investor confidence. An active role of government, therefore, is needed to supplant the fall in private spending, and create new income, spending, and economic growth.

In contrast to this “demand-side” theory of macroeconomics, the neo-classical economist would argue that China’s government would do best by letting the economy “self-correct” in times of economic slowdowns. The graph below shows that as demand for China’s output falls in the (In macroeconomics): The period of time over which wages and prices are relatively inflexible. A fall in aggregate demand will lead to unemployment and recession in the short-run. Due to the inability of the nation's producers to reduce wages paid to worker, they must lay workers off to reduce costs as demand falls.');" onmouseout="tooltip.hide();">short-run, unemployment will rise and the price level will fall as firms find it hard to sell their output. Because millions are out of work, and because prices are lower, labor will be willing to accept lower wages, encouraging firms to increase their employment of labor, shifting aggregate supply outward and ultimately restoring full-employment at a new, lower price level than before the downturn began. This classical laissez faire theory of “self-correction” has by most account been proven FALSE, as most major recessions, most notably the Great Depression itself, were ended only after massive intervention by the national government.

The most promising solution to the looming social and economic nightmare it faces is for the Chinese government to push forward massive fiscal stimulus plans aimed at putting the tens of millions recently jobless back to work. This may sound like a return to communism at first, but government money can be spent to create jobs in private enterprise, producing goods, services, and infrastructure that leads to real long-run economic growth fueled by domestic, not foreign, demand for Chinese output.

For too long China has depended on demand from the rest of the world to grow its economy. Faced with the largest economic crisis of the modern era, the Chinese Communist Party should take it upon itself to reduce the nation’s dependency on foreign demand, stimulate growth through new public spending on infrastructure, education, health care and social security for the hundreds of millions of Chinese who are left to fend for themselves once they’ve reached retirement age. Meaningful fiscal stimulus aimed at improving the lives of the common citizen, of whom so many have been adversely affected by China’s over-dependence on export-oriented growth, will may be the best response to the most dire social and economic turmoil the country has faced since the end of the Mao era over 30 years ago.

Discussion questions:

  1. What is China’s most worrying macroeconomic problem currently? Inflation? Recession? Unemployment? Deflation? Trade imbalance? Income distribution? Which of these does falling demand for China’s exports affect most?
  2. What are the social and economic costs of rising unemployment and why is it so important for a government to combat it?
  3. Discuss the differences in the Keynesian and the Classical models in their explanation of what will happen to unemployment after a fall in Aggregate Demand.
