Why has income inequality increased in the US?
-Rapid technological change has decreased the demand for "unskilled" workers relative to "skilled" workers -Expanding international trade has had the same effect -Increased immigration (legal and not) has brought more unskilled workers to the United States -Market characterized by tournament pay; a few people at the top earn very highly -Assortative mating: The tendency for men and women of similar educational backgrounds to marry has increased, which raises income inequality across households -Luck

E. 10%.
What is the relationship between government failure and market failure?
Government failure is market failure due to government intervention rather than to externalities
Define the Benefits-Received Principle
Holds that governments ought to charge more in taxes to people receiving more benefits from taxes. Funding locally-operated services like snow-plowing and road-maintenance at the local town or county level follows the benefits-received principle. However some government services are designed to help poor people; taxing those people to pay for those services is probably counter-productive. Similarly, it is often difficult to identify exactly which groups are helped by particular government activities
Define the Horizontal Equity Principle
Holds that people in the same economic situation ought to pay similar amounts in taxes. This is not easy to apply in practice. If two people each earn $50,000, horizontal-equity seems to suggest taxing each the same amount. But if one receives the income by working two 40-hour a week jobs, while the other receives the income from a lottery annuity, these two people do not seem to be in the "same economic situation"
Define the Ability-to-Pay Principle
Holds that revenue from taxes ought to mostly be paid by the rich—that is, those who have a higher ability to pay. In practice, this means that people with higher incomes end up paying more taxes, a concept known as vertical equity. Income and wealth do correlate, but not perfectly. Income taxes are progressive, reflecting the ability-to-pay principle
Define Regulatory Capture
In principle, regulatory agencies like the Food and Drug Administration (FDA) exist in order to safeguard consumers, but firms that are significantly affected by regulatory agencies have an incentive to make sure the agencies are "on their side". An agency which is acting more in the interest of the firms it is supposed to regulate has been subject to regulatory capture. Ex. The defunct Interstate Commerce Commission was set up to regulate railroads and trucking firms, but ended up preventing competition in the industry instead
Has inequality in the distribution of income in the United States increased or decreased over time?
Income inequality in the US has increased since 1970. US is one of highly unequal countries among advanced countries. However, income inequality figures don't consider the following: Substantial income mobility The effects of government programs meant to reduce poverty
Which type of tax raises the most revenue for the federal government?
Individual income taxes
Government spending must be financed somehow; most revenue relies on taxation, including what taxes?
Individual income taxes, social insurance taxes, corporate income taxes, sales taxes, property taxes, excise taxes
Inequality of income is caused by what?
Labor productivity, the productivity of capital owned, technological change, and the extent of international trade
Explain Property Taxes
Most local governments tax homes, offices, factories, and the land they are built on. In the US, this is the largest source of funds for public schools
Explain Sales Taxes
Most state and local governments tax retail sales of most products.
Define Logrolling
Politicians gaining support for their own proposals by offering to support those of their colleagues. Helps explain why sugar quotas continue to exist, even when they benefit relatively few people. The loss of surplus per person to the sugar quota is small; many voters remain rationally ignorant of such "irrelevant" ideas
What are the two viewpoints of the Samaritan's dilemma?
Positive: low income families with transfers helps the poor Negative: Discouraging work incentive of the poor
Define Social Security
Provides cash payments to elderly retired workers, the disabled, and widows/widowers with children. Administered by the federal government
Define Medicaid
Provides health care to poor people. Administered by states, but federally mandated and funded through federal grants
Define Temporary Assistance for Needy Families
Provides various forms of financial assistance for a limited time to poor families. Administered by states, but federally mandated and funded through federal grants
In 2012, Congress and President Barack Obama passed legislation raising tax rates on families earning $450,000 or more. Did this change in the law make the U.S. tax system more progressive or less progressive?
Raising taxes on high-earning families will cause the U.S. tax system to become more progressive because those with higher incomes will pay a larger percentage of their incomes in tax
Which type of tax raises the most revenue for state and local governments?
Sales Tax
Define Lorenz Curve
Shows the distribution of income by arraying incomes from lowest to highest on the horizontal axis and indicating the cumulative fraction of income earned by each fraction of households on the vertical axis
What are some policies to reduce income inequality?
Taxes and transfers Improving human capital
Define Human Capital
The accumulated knowledge and skills that workers acquire from formal training and education or from life experiences. Since human capital is not distributed equally across workers, neither will income
Define Tax Incidence
The actual division of the burden of a tax between buyers and sellers in a market
Define Voting Paradox
The failure of majority voting to always result in consistent choices
Explain Excise Taxes
The federal government and some state governments levy excise taxes on specific goods like gasoline, cigarettes, and alcohol
Explain Individual Income Taxes
The federal government, most state governments, and some local governments tax the wages, salaries, and other income of households and the profits of small businesses, which are typically taxed the same as wages and salaries.
Define Marginal Tax Rate
The fraction of each additional dollar of income that must be paid in taxes. Economists tend to concentrate on marginal tax rates, since these are most relevant for labor supply decisions: they apply to any additional income that people earn
In selecting which taxes to use, governments take into account what goals and principles?
The goal of economic efficiency The ability-to-pay principle The horizontal-equity principle The benefits-received principle The goal of attaining social objectives
Define Corporate Income Taxes
The government taxing corporations on their earnings. These are also progressive, with tax rates from 15% to 35%; but unlike for individuals, most corporate earnings are taxed at the 35% level
Define Gini Coefficient
The larger the area between the actual Lorenz curve and the perfect equality Lorenz curve, the more unequal are incomes. We measure this inequality with the Gini coefficient. Gini coefficient = A/(A+B). Perfect equality in incomes would give a Gini coefficient of 0; if all income was earned by one person, the Gini coefficient would be 1
Is Marginal Tax Rate or Average Tax Rate more important in determining the impact of the tax system on economic behavior?
The marginal tax rate
Define Poverty Rate
The percentage of the population that is poor according to the federal government's definition. Decreases in the poverty rate in the 1960s came largely from the expansion of Social Security.
How has the poverty rate changed in the United States since 1960?
The poverty rate has decreased from between 20 and 25 percent in 1960 to between 11 and 15 percent for the past 40 years
Define Median Voter Theorem
The proposition that the outcome of a majority vote is likely to represent the preferences of the voter who is in the political middle
What determines tax incidence?
The relative price elasticities of the demand and supply curves. When the demand for a product is less elastic than the supply, consumers pay the majority of the tax on the product. When demand for a product is more elastic than the supply, firms pay the majority of the tax of the product
Define Average Tax Rate
Total tax paid divided by total income
What are the problems with transfers?
Transfers have expanded substantially. These transfers have been largely ineffective at reducing the poverty rate
