What is the difference between risk spreading and diversification as strategies for reducing risk?
Risk spreading means that a big risk is broken into smaller risks so that a bunch of people can take on a small part of the one big risk. The probability of loss or reward is unchanged but the size of the gain or loss is much smaller. Diversification is when the decision maker takes on a large number of small risks. The total value of the group of small investments may be the same value as the large option, but with diversification, there is less risk of loss becuase it is unlikely all the small investments will turn out badly at the same time. The more dissimilar the investments are the less likely it is that they will swing in the same ways. Diversification does not reduce systemic risk.
Why are people more hesitant to make risky choices when the stakes are large than when the stakes are small?
When stakes are large the potential loss is much greater than when the stakes are small even if the probability is the same. A large loss means greater impact on wealth. Diminishing marginal utility indicates that the extra dollars lost in large losses are associated with greater per dollar losses in utility than in a small loss. Example if there were a $100 loss or a $1,000 loss, the loss of $100 is the same impact on utility in both cases, the extra $900 of loss in the second case decreases utility by more than 9 times the $100 loss.
Explain how income redistribution programs reduce the work incentive of both high-income tax payers and low-income benefit recipients.
Work incentive is tied to net gain from working which is viewed in terms of take-home income. Income redistribution programs-- take income from high-income households through taxes to fund transfers of income (in-kind benefits) to low-income households. when taxes are increased on high-income households their after-tax income falls reducing their reward for work effort. When transfer payments are means tested low-income households recive transfer payments and would receieve reduced benefits if they increased work efforts to earn more income. Increased work efforts would yield little added benefit to household providing low incentive to work

social insurance programs
The three main approaches that governments use to reduce inequality and poverty are providing a social safety net, proving social insurance programs, and designing tax systems. Briefly explain how each can be used to reduce inequality and poverty.
social safety nets provide income or in-kind transfers when income falls below set poverty line. But they alone do not provide enough support for person to move out of poverty. Means-tested programs that are funded through tax revenues. Social insurance programs are not means tested and available to all. Help to provide insurance for bad outcomes like job loss, disability or old age. Progressive tax systems have rates that rise on additional income so those with higher incomes pay more than those with less. Tax credits can potentially move people out of poverty.

What is a consumer's reservation price? How does a consumer's reservation price relate to price discrimination?
t is the highest price they are willing to pay for a product. It represents the marginal benefit that the consumer would receive from the product. Through price discrimination, a manager wants to charge each customer a price at or close to their reservation price to maximize revenue. But the manager will not reduce price below marginal cost for last customer.

How does brand proliferation create a barrier to entry in a market?
Brand proliferation occurs when existing company produces multiple versions of a product to appeal to differing consumer preferences. When companies do this, a new company may be discouraged from entering a market since it is more difficult for the new company to differentiate its product from the many versions already available.
Why would a seller use the hurdle method to price discriminate rather than group pricing?
Group pricing is a type of price discrimination that works by charging different prices to different groups of people. Groups are determined by buyers with differing demand, verifiable and difficult-to-change characteristics. If this information about buyers is not available then you can't group price and need to use the hurdle method. Hurdle method requires all buyers to overcome a hurdle or obstacle to qualify for the lower price. Those who are more price sensitive (lowest reservation price) will be more willing to overcome the hurdle to get the lower price.
. Between 1970 and 2014, the share of income earned by the bottom quintile in the United States fell from 5.4% to 3.6%. However, this does not mean that the incomes of those in the bottom quintile fell. Explain how people in the bottom quintile could earn a lower percentage of total income and yet not have lower incomes.
If total income earned rises significantly then smaller percentage of the total income could be a higher dollar amount. Distribution of income becomes more unequal even though incomes are rising overall.

Increase in the use of e-books has reduced the demand for physical books. How has this impacted the labor market for bookstore managers? Explain the change in the market.
Reduced demand means that there will be reduced use of bookstores and reduced demand for bookstore managers. As the demand for managers decreases, the price (their wage) decreases and the equilibrium quantity (hours of manager's time) will also decrease. This means fewer opportunities to work as bookstore managers

Briefly describe how each of the five forces in the Five Forces framework impacts the profitability of companies in a market.
when there are many competitors (1) it is hard to charge a high price because customers have other companies to choose from. Potential competitors (2) can drive down price.. existing companies feel threatened and charge lower prices to avoid attracting new entrants. Threat of competitors in substitute markets (3) means there are other types of products that can be substituted for your company's product. If the price is high enough its customers will switch from your product to another. Supplier bargaining power (4) impacts cost of production rather than revenue. If the company must purchase inputs in an input market where sellers have bargaining power, the sellers can charge higher prices raising costs of production and reducing profits for that company. Buyer bargaining power (5) means biyers with market or bargaining power can push price down to lower levels reducing the company's profits.
