1. Income, Inequality, and Poverty 15

2. Big Questions 1.What are the determinants of wages? 2.What causes income inequality? 3.How do economists analyze poverty?

3. The Non-Monetary Determinants of Wages Compensating Differentials –Extra income that must be paid to perform a job –People who do dangerous, stressful, risky, or unpleasant jobs get paid more, ceteris paribus –“Fun” jobs may get paid less

4. The Non-Monetary Determinants of Wages Education and human capital –Human capital are the skills acquired through education and training

5. Education and Pay

6. The Non-Monetary Determinants of Wages Location –People may be willing to accept lower wages to work in areas that are more desirable to live in –Areas with a high cost of living will pay higher wages Lifestyle –Wage is not top priority for some individuals –Workers of nonprofits, religious organizations, caretakers, musicians, artists, etc.

7. The Non-Monetary Determinants of Wages Union –Able to increase wages by threat of a strike, or work stoppage Binding arbitration –An impartial third party makes decision in wage and benefit negotiation if workers and employers cannot reach agreement

8. Union History 1950s –One in three jobs was unionized –Union wage premiums as high as 30% Today –One in eight jobs unionized –Wage premiums between 6 and 15% Why the change? –Competition from the private sector –High labor costs cause firms to use more capital or relocate to nonunion labor areas –Unions still common among public sector where cost containment isn’t as much of an issue and competition is absent –Public school teachers, police, fire, and sanitation workers

9. Are Unions Still Necessary? Early unions –Protected workers from monopsony employers –Classic example: company town, coal mining –Established worker protection laws for dangerous jobs Today –With increased safety, increased labor mobility, and increased private competition, are unions needed? –Some fear that unions have outlived their purpose and remain an inefficient and costly relic of the past –Mandatory breaks, worker slowdowns, etc.

10. Teachers’ Unions Normative question: what should teacher’s unions do? –Ensure decent wages and working conditions for people doing an important job –Prevent unfair firings Unintended consequence –Some believe the unions have become TOO powerful –Has become nearly impossible to fire bad teachers –Teachers paid to NOT teach because it’s cheaper than trying to take on the union and fire them

11. Efficiency Wages –Wages higher than equilibrium –Offered in hopes of increasing worker productivity –Reduce shirking, reduce turnover –Hopefully efficiency gains are greater than the increase in wage costs

12. Non-Monetary Determinants of Wages

13. Wage Discrimination Wage discrimination –Occurs when workers of the same ability are not paid the same as others because of their race, ethnicity, sex, age, religion, or some other group characteristic Legislation to prevent discrimination –Equal Pay Act of 1963 –2009 Fair Pay Act—gives employees more time to file a complaint with the government

14. Gender Wage Gap Finish the phrase: for every dollar a man earns, a woman earns... –75 cents Think about this phrase –Is this true? –Did it used to be true but now isn’t? –Is this huge difference caused entirely by discrimination? –Can economics explain the difference?

15. Gender Wage Gap Today –Female workers earn 23% less than males –Mostly due to compensating differentials rather than discrimination Explanations –Men more likely to work outdoors (road work, construction) or in more dangerous conditions –Women leave the labor force more (child or elder care) Trends –Wage gap is shrinking –Women have a 3-to-2 majority in college degrees

16. Other Wage Differential Explanations Cultural differences –Some cultures place more emphasis on education, which leads to higher human capital, higher productivity, and higher wages Location –Higher costs of living in cities often translate into higher wages Life cycle –Wages rise, peak, and then fall as a worker ages –Workers near retirement are less likely to learn new techniques or keep up with technology

17. Median Annual Earnings by Group

18. Occupational Crowding Occupational crowding is often referred to within the context of wages for men and women –Women may be crowded into jobs –The higher supply of labor lowers wages With today’s increased opportunities, why don’t more women leave the lower-paying jobs and become engineers? –Rigidity in changing careers –Social customs –Personal preferences

19. Where the Men Aren’t

20. Economics in Anchorman: The Legend of Ron Burgundy Occupational crowding Ron Burgundy loses his job... to a woman!

21. Winner Take All Winner take all –Exists when relatively small differences in ability lead to large differences in compensation Examples –Professional athletes Major leaguers earn much more than minor leaguers, even though playing abilities are often not that much different –CEOs Some CEO salaries today are more than 500 times greater than the average worker for the firm

22. Inequality of Income Income inequality exists when some workers earn more than others. Caused by –Compensating differentials –Discrimination –Corruption –Differences in marginal product of labor

23. Measuring Inequality

25. Understanding Observed Inequality Why does the United States have a higher inequality ratio than Germany or Canada? –Similar poverty rate (26.3%) to other developed countries –However, the top earners in the United States earn much more compared to other countries

26. Understanding Observed Inequality High-income inequality also occurs in countries that are very poor and less developed –This is due to the lowest income people having much less income (compared to low-income individuals in developed countries)

27. Difficulties in Measuring Inequality Income inequality numbers can be unreliable and misinterpreted –Data reflects pretax income, rather than disposable income –Does not account for in-kind transfers, (goods and services given to poor rather than cash) –Does not account for unreported or illegal income. Black markets may play a larger role in less developed countries, further skewing this. –No (monetary) value is placed on goods or services produced at home—child-rearing or growing vegetables

28. Difficulties in Measuring Inequality Are the shortcomings a serious measurement issue? –Each individual year, probably not –Across generations, maybe so Comparing inequality today to 50 years agp would probably violate many ceteris paribus assumptions. Birth rates, tax rates, population age, and technology all change. Need to figure out exactly what causes changes in income inequality; tough to do if many things change Further problems? –Assuming income distribution is a reflection of welfare; we may also value leisure, safety, community, etc.

29. Income Mobility Income mobility –The ability to move up and down the economic ladder over time Higher levels of income mobility? –Give workers an incentive to improve human capital and work harder –Workers have increased change of rewards –Poverty may be only temporary

30. Income Mobility in United States

31. Income Mobility Marginal poor –Poor at a point in time, but have skills to move up the ladder –Low earnings are the exception –Willing to borrow to make a big purchase –Fit well into life-cycle theory model –Student straight out of college Long-term poor –People who lack the skills to advance to higher income levels

32. Poverty Poverty rate –Percent of population whose income is below the poverty threshold Poverty threshold –The income level below which a person (or family) is considered impoverished –Adjusted each year for inflation –Does not include in-kind transfers –Does not include geographic cost-of-living differences

33. Poverty, Historically Equal Opportunity Act, 1964 However, poverty rate has remained stagnant for about 40 years. Why? –Gains from growth have accrued to the middle and upper class rather than the poor –Many low-income workers continue to lack skills to earn higher wages Solution? –Not easy—perhaps long run investment in education and skills aimed at poor –Job retraining for structurally unemployed

34. Poverty Rate for Households

35. Poverty Rate for Various Groups

36. Poverty Policy Many policies (each with their costs and benefits) have been designed to address poverty Two conflicting motivations –We want to give generously –We want the poor to become self-sufficient Policies –Welfare –In-kind transfers –Earned income tax credit (EITC) –Minimum wage

37. Welfare Not a government program but a series of initiatives –Monetary payments –Subsidies and vouchers –Health services, housing –Examples: TANF, SSI, SNAP Who receives this? –Unemployed, disabled, veterans, dependent children –Eligibility is often limited by time and only if income is below a cutoff amount

38. In-Kind Transfers Direct assistance in the form of goods and services –Food banks, housing shelters, private charities, health care through Medicaid Why give goods and services rather than cash? –Mainly to prevent the misuse of funds –Possibility of cash transfers going to alcohol, gambling addictions, or expensive clothes –In-kind transfers can be targeted at essential services

39. Earned Income Tax Credit The EITC is a refundable tax credit designed to encourage low-income people to work more –Can lower taxes as much as $6,000 per year –Helps over 20 million families, making it the largest poverty-fighting policy –Benefits are phased out over higher incomes, so there is no sizeable work disincentive at a specific cutoff The EITC is a form of a negative income tax –This is a tax credit that is paid to poor households out of taxes collected from middle- and upper-income taxpayers

40. A Negative Income Tax

41. Minimum Wage Discussed previously—a price floor on wages in labor markets However, the same problems can be discussed –Low-skill people may be less productive –Firms may hire less low-skill workers –Minimum wage doesn’t guarantee employment

42. Problems with Traditional Aid There is one glaring problem with assistance for low-income individuals. Many welfare programs create work disincentives! –Often when income is increased, many benefits are severely reduced or eliminated –People may consciously work less to keep their benefit eligibility –The EITC does the best at addressing the work incentive problem by having phased-out assistance

43. Problems with Traditional Aid: A Mathematical Example Family of five earns $20,000 a year, and qualifies for $10,000 in annual welfare benefits –Total income for the year is $30,000 What happens if earned income rises to $30,000 per year? –$30,000 earned income disqualifies the family from receiving much of the assistance it previously received. Benefits fall from $10,000 to $2,000 –Family earned $10,000, but lost $8,000 in welfare benefits. That’s similar to an 80% marginal tax rate! –That is a strong disincentive to work!

44. Problems with Traditional Aid Samaritan’s dilemma –Occurs when an act of charity causes the recipient not to work hard on their own to escape poverty –Another example of an unintended consequence Addressed by Bill Clinton in 1996 as part of welfare reform –As part of TANF, he encouraged states to require employment searches as a condition for benefits –Also put a five-year maximum on benefits –Changed from entitlement to temporary safety net, reducing the samaritan’s dilemma

45. Economics in Million Dollar Baby Welfare and the samaritan’s dilemma Can people become dependent on welfare?

46. 100% Inheritance Tax Would a 100% inheritance tax decrease wealth inequality in our country? What if we combined it with a redistribution policy? Some normative statements –“It’s not fair. She was born with a silver spoon and she’ll inherits millions while I have to work all day” –“He earned his money. He should be able to give it to his kids if he wants.” –“Why should the government (or anyone else) get to take what I earn? Double taxation!” –“We should all start out on the same footing.”

47. 100% Inheritance Tax Incentives created from a 100% inheritance tax: –People may start frivolously spending. If I can’t keep wealth in my family after I die, may as well blow it now. –People will “launder” money to their children. Cash and other gifts will be given to avoid the tax. People will have the incentive to do financial planning earlier in their life before its too late. Currently –You can give anyone $13,000 per year as an untaxed “gift.”

48. Economics in Milton Friedman— Redistribution of Wealth Watch this Q & A session about wealth distribution and the 100% inheritance tax

49. Conclusion Income inequality in itself is neither good nor bad –Too equal incomes = work disincentive –Too unequal incomes = political unrest Welfare policies can help decrease the problem of income inequality –However, they must be designed correctly as not to create work disincentives

50. Summary Non-monetary determinants of earnings include compensating differentials, human capital, location, lifestyle, unions, and efficiency wages. Economic studies of wage discrimination have found that the amount of discrimination is relatively small—accounting for 3 to 5 % of wage differences. Despite recent gains, women still earn significantly less than men. The wage gap can be partially explained by occupational crowding.

51. Summary Some amount of income inequality is to be expected in a market economy. Economic mobility reduces inequality over long periods of time. The poverty rate in the United States has been stagnant for the last 40 years, despite many efforts (welfare, in-kind transfers, and the EITC) designed to reduce it.
