Econ Midterm 2
Why does labor demand slope down?
-Diminishing Marginal Product -Declining Output Prices -Labor-Capital Substitution
Labor-capital substitution
-Higher wages make machines cheaper, relative to labor -when wages are $10 per hour, have humans do everything at McDonalds, when wages increase to $30 per hour, have machines take over some tasks
What are the costs of redistribution?

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

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

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
declining output prices

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

adds more revenue than it adds to costs
An interaction between two or more persons is considered a strategic interaction when:
an individual's best choice may depend on what the others choose, and others' best choice may depend on what the individual chooses

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

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

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

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
