Accept low wages for

-chance of promotion -long vacations -satisfying work

What are the 3 factors that explain the differences in wages?

-demand -supply -insitutions

Falling machinery prices will cause

-falling wages for low-skill labor -rising wages for high-skill labor

How are firms affected by increased globalization?

-greater competition: limits firms' ability to increase prices -outsourcing: re-allocating tasks overseas -larger global market: crating a larger market for specialized products, increasing the variety of goods available to consumers -Interdependence Increases: benefit from economic growth in other countries

Why are CEO's paid so much?

-hiring the best CEO instead of the 250th best raises the value of company by 0.016% -as firms get larger, the value of a top CEO rises

Signaling

-how can employers identify hard workers? -hard workers are more likely to complete College -Solution: hire college grads

The Demand for Superstars

-huge audience -each of whom is willing to pay a little more for "the best" -yields a huge payoff for being best -technology can make a potential audience larger

What are the cases for limiting International trade?

-national security -infant industry -unfair competition -domestic regulations -saving jobs

market power is determined by

-number of competitors product differentiation/uniqueness

Incentive

-opportunity to make yourself better off -something that induces a person to act -people respond to incentives by acting to make themselves better off

effects of minimum wage

-raise a lot of peoples wages -small disemployment effects -poorly targeted social policy

Demand and determining wages

-what kind of workers do employers want? employers demand human capital

what happens when you raise prices in a monopoly?

-won't lose customers to competitors because there are no competitors -will lose them to other products

Sources of Comparative Advantage in int. trade

1. Relatively Abundant Inputs 2. Specialized skills 3. Mass Production

What shifts labor demand?

1. Shifts in demand for your output: increase in demand so more people are hiring. wages increase because its highly demanded and quantity increases because its highly demanded 2. Changes in the capital stock: machinery is a substitute for low skill labor and machinery is a complement for high skill labor. 3. Management techniques and technological progress: new technologies and better management lead firms to do more with less. Giving more technologies to a worker helps them do more. Increases in the marginal product of labor

What are the labor supply shifters?

1. Wages in other jobs -If wages in other jobs rise then decrease supply of workers -If wages in other jobs galls than increase supply of workers 2. Income and Payroll taxes -labor supply decisions depend on after-tax wage -taxes on workers shift the labor supply curve 3. Income support programs -The opportunity cost of work is unemployment. 4. Value of leisure -high value of leisure is a disincentive to work

A table showing the potential outcomes arising from the choices made by decision makers

Hawk/Dove Games

A type of anti-coordination game where in each equilibrium there is a "winner" and a "loser"

Compensating differential

Human Capital

Accumulated knowledge and skills that make a worker more productive Ex: Each year of College raises your long-term earnings by about 8% -increases your productivity

Unions

An association of workers, formed to bargain for better working conditions and higher wages. Negotiate with employers -increases bargaining power -increases wages by 10-20% -restrict the supply of labor and increase wages

Business looking to hire (buyers)

Trade

Buy what you're relatively bad at...exchange of goods and services. - about maximizing opportunity cost -economic surplus is maximized when each task is done by the person with the lowest opportunity cost... everyone has the lowers opportunity cost in something so this is why we trade

The strong incentive of sellers to deter the entry of new sellers is a major reason that:

Most markets are imperfectly competitive

Why is a "Nash equilibrium" called an equilibrium?

prefect competition

a market structure in which a large number of firms all produce the same product. -lost of sellers -standardized product: milk, bleach, grain... nor product uniqueness... all products are identical -firms have to charge the market price "price takers" -no market power

monopolistic competition

imperfect competition

a market structure that fails to meet the conditions of perfect competition

Prisoner's Dilemma

a particular "game" between two captured prisoners that illustrates why cooperation is difficult to maintain even when it is mutually beneficial. The category of games in which players have a dominant strategy to "cheat" preventing beneficial cooperation from occurring -cheat=turning someone else in

Nash Equilibrium

a situation in which economic actors interacting with one another each choose their best strategy given the strategies that all the other actors have chosen. Most games do not have a player with a dominant strategy. - a way of predicting what will happen in a game -strategy not an outcome

equlibrium

a situation where nobody has an incentive to do something different

dominant strategy

a strategy that is best for a player in a game regardless of the strategies chosen by the other players. A strategy that is always best regardless of what the player does

employers

Policy debates invoke ethical debates informed by different notions of fairness:

equality of opportunity, equality of outcomes, fair process (same rules apply to everyone), what each person "deserves"..earned success rather than luck

Coordination Games

everybody benefits if the problem is solved, so the trick is to get everyone common knowledge about the situation and its solution. The category in which multiple Nash equilibria exist, each corresponding to each player doing what the other players are doing. Ex: Union Strikes, Cheating, Peer Pressure, Bank Runs

market demand curve equals

firm demand curve

social insurance

Typically, when a firm increases its prices, quantity decreases, but not all the way to zero. Why?

law of demand

The___wage resulting from an employer with monopsony power can be offset through____

low; minimum wage laws

specialization

make what you're relatively good at

marginal cost

cost of redistribution

moving the money is costly

Nash Equilibrium

occurs when both payoffs are underlined

similar; different; their jobs differ in things like risk or enjoyment

In Market power/compeition the demand curve

slopes down -increase price, lose some customers but not all

Examples of Social Insurance

social security, medicare, unemployment insurance, disability insurance, workers' compensation

What are the 2 effects of a higher wage on labor supply?

substitution effect: -higher wage makes more attractive relative to leisure -work longer hours Income Effect: -you don't have to work as long to buy the same amount of stuff -work fewer hours -what is the point of making so much money if you don't have time to relax and spend it

Market Power

the ability of a single economic actor (or small group of actors) to have a substantial influence on market prices. Ability ti have power of the market - power=ability to increase your price -ability to raise prices without losing many sales to competing sellers -determines your best pricing strategy

comparative advantage

the ability to produce a good at a lower opportunity cost than another producer. The ability of an individual or group to carry out a particular economic activity more efficiently than another activity. - lower opportunity cost -drives trade

Trade Costs

the extra costs incurred as a result of buying or selling overseas, rather than domestically Ex: shipping costs, taxes paid on imports or exports, language barriers, time zones - when trade costs are high, goods are not imported or exported

gains from trade

the improvement in outcomes that occurs when producers specialize and exchange goods and services....you produce more together than apart

wages and unemployment are determined by what?

the labor market

minimum wage

the lowest hourly wage that employers are allowed to pay

diminishing marginal product

the marginal product of an input declines as the quantity of the input increases. Ex: When Mark Zuckerberg hired his first coder, that benefitted Facebook a lot because it freed him up to grow the business. Hiring one more coder now will not have a large impact

Labor Demand

the marginal revenue product curve -keep hiring until wage=MRP Marginal Product X price of output

What does the fries demand curve summarize?

the quantity buyers demand from your firm as price changes

Specialized Skills

the unique knowledge and abilities needed for specific occupations. Even when land, labor, and capital are all similar, better production techniques will lower your opportunity costs Ex: US makes best movies...best film makers want to move to Hollywood

Labor Supply

the willingness and ability to work specific amounts of time at alternative wage rates in a given time period. The time you spend working in the market -all about opportunity costs -keep working until wage/cost=marginal benefit of leisure

Multiple equilibria exist when:

there is more than one equilibrium

If labor demand is inelastic there is a ___ decline in employment

tiny

Discount Effect:

to sell one more unit, you have to lower the price on all units sold. - this is unique to firms with market power

True or False: income inequality has been rising

true

True or False: most spells of poverty are brief but most poor people are in long-term poverty

true

True or false: many people experience poverty at some point

true

Ture or false, monopoly has the most market power?

true, because there are "no" competitors because they have a completely unique product

Supply and Determining Wages

what do employees want?

The opportunity Cost of working is

what you would have done during the time if you were not working

Cartels

when 2 firms come together and agree to charge a high price

Rational Rule for Workers

work one more hour as long as the wage is at least as large as the marginal benefit of another hour of leisure. -Keep working until wage=marginal benefit of leisure

Does the labor demand=marginal revenue product curve

yes

Anti-Coordination Games

your best response is to take a different action to the other player. Games with multiple Nash equilibria, each of which over when the players don't choose the same strategy
