Unit 3 - Social Welfare and Insurance Flashcards
What outcomes should we care about/are good measures of well-being?
earnings, income, consumption, wealth, health
earnings
Main source of income for most people; easy to measure
from a job
income
More comprehensive than earnings; fairly easy to measure
from all sources - wages, investments, businesses, rental property
consumption
Public/private transfers, savings/dissavings
This goes into utility function; harder to measure
includes
-spending (what to buy)
-economist’s view: people care about this
utility (happiness) = f(good 1, good 2)
savings - adding to pile of wealth (not everyone can effect)
dissavings - taking $ out of pile of wealth to spend ASAP
wealth
Why save?
A) shocks;
B) future consumption (retirement)
C) kids
Comprehensive utility function includes all of this
health
Value for itself + affects your productivity (earnings)
absolute poverty measures
Poor if income < threshold level (poverty line)
absolute poverty threshold line in the US
2022: $27,750 for family of 4 (depends on family size)
How we got here: 1960s food budget x 3 + inflation
World Bank absolute poverty threshold line
$2.15/day (extreme poverty)
potential issues with absolute poverty measures
Arbitrary; people just above line are not well off
May not be a “living wage” that covers actual costs; regional differences in cost-of-living
May not include transfers (not consumption)
Keeps up with inflation but not rising wages
Relative poverty measures
poor if income < 50% of median income (or some %)
advantage of relative poverty measures
cutoff rises with wages, not inflation
But could have some of same other issues as poverty line
Inequality measures
90-10
Shares of income held by different quintiles of income distribution
90-10
ratio of income at the 90th percentile of the income distribution to 10th percentile (or 90-50, 50-10)
Shares of income held by different quintiles of income distribution
e.g., lowest 20% vs. highest 20% (or use groups other than quintiles; measure shares of wealth)
advantage of relative inequality measures
may be useful to compare well-being of least well-off to high (not just median) earners
economic mobility
Measure the probability that people in one quintile of family income as a child end up in each of the income quintiles as an adult
Why do we care about mobility?
Equality of opportunity requires that people can end up somewhere different from where they started
Public Good
Redistribution is a ____; private provision too little
Social insurance
Part of economic success is due to luck, want to have a system that insures us against it
There will not be a market for insurance against poverty
Egalitarianism
Everyone has a right to a basic level of certain goods (e.g, food, housing, health care, education)
Rawls’ “Veil of Ignorance”
If you did not know what position you would have in society, you would want a more egalitarian society
