Does the Pope understand economics?

This article reports that the Pope's encyclical on climate change states, "The strategy of buying and selling emissions credits can give rise to a new form of speculation and would not serve to reduce the global emission of polluting gas. This system seems to be a quick and easy solution with the appearance of a certain commitment to the environment, which however does not imply by any means a radical change in the scale of circumstances. Thus, it may become an expedient that supports continued excessive consumption by certain countries and sectors."

Hospitals are rational. Is that good for patients and taxpayers?

TOPICS: Health Economics
SUMMARY: New research in Health Affairs confirms a Wall Street Journal analysis that found a pattern of long-term-care facilities discharging patients at lucrative times.
CLASSROOM APPLICATION: Students can evaluate the effect of Medicare payment rules on hospital discharge decisions. Instructors can present the Medicare-hospital relationship as a principal-agent problem with hidden information (in which the hospitals have private information about the health status of patients).
QUESTIONS: 
1. (Introductory) What is the evidence that long-term-care hospitals are responding to the financial incentives in their discharge decisions? Is this evidence refutable?

2. (Advanced) What is the principal-agent problem with hidden information? Is the case described in the article one of these problems?

3. (Advanced) Should Medicare use a step function (i.e., payment thresholds) to determine hospital reimbursements?

Lies, damned lies, and accounting

This article describes how costs accountants record in their books fails to reflect accurately opportunity costs.

Chipotle's ads

TOPICS: Advertising
SUMMARY: Health-food advertising depends on the eagerness of the customer to be fooled. "Over the years the courts, in enforcing the Lanham Act, a federal law banning false advertising, have carved out a considerable zone for 'puffery.' Puffery, as one case puts it, is 'an exaggeration or overstatement expressed in broad, vague, and commendatory language. Such sales talk is considered to be offered and understood as an expression of the seller's opinion only, which is to be discounted as such by the buyer.'... Of course, because such advertising depends on the eagerness of the customer to be fooled, a better solution than lawsuits might be an education system that lowers the general level of idiocy in the population."
CLASSROOM APPLICATION: Students can evaluate whether the advertising presented in this week's Business World column improves consumer welfare. If consumer preferences are rational (about GMO foods for example), then the information provided by the advertising noted in the column could improve consumer welfare. However, if the advertising is persuasive, then perhaps consumer welfare is reduced.
QUESTIONS: 
1. (Introductory) What is puffery? Does the Lanham act, which bans false advertising, prohibit puffery as well?

2. (Advanced) What is the distinction between informative advertising and persuasive advertising? What are examples of informative advertising? What are examples of persuasive advertising?

3. (Advanced) Is Chipotle's announcement that the company plans to stop using genetically modified ingredients persuasive advertising, informative advertising, or possibly both?

4. (Advanced) What is the effect of informative advertising on consumer welfare? That is, does this type of advertising make consumers better off?

LA raises minimum wage

This article reports that teh City Council in LA approved a plan to increase the minimum there to $15 / hour. We will be talking about minimum wage next week. Here are three questions.
  1. How effective is an increase in the minimum wage at fighting poverty? "The council's decision is part of a broader national effort to alleviate poverty, said Maria Elena Durazo, former head of the Los Angeles County Federation of Labor."
  2. How much would an increase affect employment opportunities for low-wage workers? "'The very people [council members'] rhetoric claims to help with this action, it's going to hurt,' said Ruben Gonzalez, the Los Angeles Area Chamber of Commerce's senior vice president for public policy and political affairs. He predicted that many businesses would absorb their new labor costs by laying off employees, reducing work hours or moving out of the city entirely." 
  3. Why are unions the big supporters of the plan? "The vote was the latest show of organized labor's clout at City Hall. During nearly a year of often emotional debate, labor leaders never gave ground on their central demand that the minimum wage rise to at least $15." The article mentioned support from Maria Elena Durazo, former head of the Los Angeles County Federation of Labor, now with Unite Here, the hotel and restaurant workers' union.

Is a guaranteed basic income a good way to help poor people?

The article discusses the pros and cons of a guaranteed minimum income, an idea Milton Friedman defended as a better way to help poor people than welfare, subsidized housing, food stamps, and the minimum wage. We discuss minimum wage after Test 1.


Audrey Hepburn teaches economics

Why would unions want the "freedom" to agree to contracts that pay less than the minimum wage after saying earlier that no one deserves to work for less than a sub-minimum wage?

Should unions also have the freedom to agree to contracts that have less health insurance than specified by Obamacare?

Should individuals have the same freedom?
