Professor R. Jisung Park PA 111 – Microeconomics: Market Failures and Inequality 4 May, 2022 Short Essays Assignment #3 1. Economic mobility is the ability for an individual to change their relative economic standing. In other words, mobility is the likelihood that an individual can become more wealthy or more poor in relation to those around them over a period of time. Economic mobility is distinct from economic inequality because economic inequality is the economic distance between the richest and the poorest and mobility is how easy it is to move up or down along that distance of inequality. 2. Wealth inequality is inequality in the amount of money individuals have which includes generational accumulation and debt, meaning many people have negative wealth if they are in debt; wealth is a stock as compared to a flow. Income inequality is inequality in the money a household makes through work or investments and does not include debt; income is a flow. Consumption inequality is the difference in what is achieved with both wealth and income in a household; this is a different measure because money invested in property or stocks contributes to wealth but is not able to be used for consumption when it is invested. 3. I think while it is easier and more feasible to pay attention to income inequality (and easier to adjust as a result of progressive income taxes), it is ultimately more important to pay attention to wealth inequality. Wealth that accumulates over generations puts individuals in better positions to get an education or a job if they grow up wealthy. Individuals that have generational wealth can also work a low-paying job and still be very well-off and able to afford living expenses, but they wouldn’t pay as much taxes as someone that grew up in a low-income household that now makes a lot of money in their job. Wealth taxes or policies that focus on wealth inequalities would also account for debt, meaning people that are still paying off student loans wouldn’t have to pay as much taxes as people that make a lot of money and didn’t go to school. 4. Over the past 3-5 decades in the United States, income inequality has increased. According to the Pew Research Center, the proportion of people in the upper-income tier in the U.S. rose from 14% to 20% from 1971 to 2019. The proportion of people in the lower-income tier also increased, meaning inequality has increased when there are fewer people in the middle tiers and more in the upper- and lower-income tiers. Additionally, the median middle-class income increased by 49% from 1970 to 2018 while the median upper-class income increased by 64% over the same period (Horowitz et al., 2020). 5. According to the OECD, the ratio of the richest quintile to the poorest quintile in the U.S. is 8.4. In comparison, the same ratio in Australia is 5.6 and the ratio is 14.5 in Costa Rica.
