Two types of economic inequality
- Wealth (accumulated assets such as savings, pensions, real estate, and stocks minus the liabilities) inequality
- The unequal distribution of accumulated assets, minus liabilities
- North America and Europe host 20% of the population yet have 67% of the world’s wealth
- China hosts 20% of the population wet have 8% of the world’s wealth etcetera
- Income inequality
- The extent to which income is distributed in an uneven matter
- Economic Big Bang - “At first countries’ incomes were all bunched together, but with the Industrial Revolution the differences exploded,… [It] pushed some countries forward onto the path to higher incomes while others stayed where they had been for millennia.” - Branko Milanovic
- Industrial Revolution accelerated the gap between the richest and poorest
- Globalisation and international trade are further accelerating this disparity
- “The triumph of globalisation and market capitalism has improved living standards for billions while concentrating billions among the few.” - Richard Freeman
- Skill-biased technological change
- Skilled workers that have the education/skills best suited for technological work whereas it has served as a replacement for unskilled workers
- Further gap between the poor and the rich and the poor and they rocking class
- As economies develop and as manufacturing jobs move overseas, low skill low pay and high skill high pay work are the only jobs left
- Other factors in exacerbating widening gap
- Reduced influence of unions, tax policies that favour the wealthy, allowance for greater CEO salaries, gender, race
- Lorenz curve graph allows us to measure the depth of income inequality
- Can be used to calculate the GINI Index - the most commonly used measure of income equality (the size of the gap between the equal distribution of income and actual distribution) with 0 as complete quality and 100 as complete inequality
- Critiques of income inequality
- Claim all income brackets are making more money but the rich’s share is growing faster
- However in the last 20 years, their average income has been falling while the rich have continually gotten richer
- “Yes, some level of inequality is built in to capitalism… It is inherent to the system. The question is, what level of inequality is acceptable? And when does inequality start doing more harm than good?” - Bill Gates
- Some economists argue greater income inequality is associated with increased violence, drug abuse, incarceration, diluted political equality (rich have disproportionate say in what policies advance and in this have an incentive to promote their own self-interest)
- Solutions
- Education, increased minimum wage, affordable, high quality childcare, provide a social safety net, adjustment of tax code to redistribute income
- Increase income taxes and capital taxes on the rich
- Progressive tax - a tax in which the tax rate increases as the taxable amount increases
- “One idea is to fix loopholes that the rich use to avoid paying taxes. Other economists argue that taxing the rich won’t be as effective as reducing regulation and bureaucratic red tape.”
- No society can surely be flourishing and happy of which the far greater part of the members are poor and miserable - Adam Smith

18 - Marginal Analysis, Roller Coasters, Elasticity, and Van Gogh

.Marginal Analysis, Roller Coasters, Elasticity, and Van Gogh - CrCo > .

● Economic Principles ..

a. Microeconomics - Study of the economic behavior of individual units of an economy (such as a person, household, firm, or industry).
b. Marginal analysis - An analysis of how individuals, businesses and governments make decisions. Marginal = Additional
c. Utility - Satisfaction or happiness people get from consuming a good or service.
d. Law of Diminishing Marginal Utility = Law of Decreasing Additional Satisfaction
e. Utils - A unit used to quantify satisfaction; they are completely subjective.
Demand curve = Marginal benefit curve
Supply curve = Marginal cost curve
f. Law of supply - An increase in price gives producers an incentive to produce more.
g. Diamond-water paradox - Although water is on the whole more useful, in terms of survival, than diamonds, diamonds command a higher price in the market.
g. Substitution effect - As prices rise consumers will replace expensive items with less costly alternatives.
h. Elasticity of demand - a measure of the relationship between a change in the quantity demanded of a particular good and a change in its price.
i. Elasticity of supply - a measure of the responsiveness of quantity supplied to a change in price.

19 - Markets, Efficiency, and Price Signals

.Markets, Efficiency, and Price Signals - CrCo > .


1. Central planning is not efficient
2. Two types of efficiency:
a) Productive Efficiency- The idea that products are made at lowest costs.
b) Allocative Efficiency- State of economy in which production represents consumer's preference.
3. Central planners are less likely to be allocatively efficient because they have a harder time getting feedback about what people want.
4. Price Signals tells you what consumers are willing to by at higher prices.
5. Price gouging: When sellers sells essential items (e.g water, food etc) at much higher price than reasonable.
6. Below-Cost Pricing: This is also called Predatory Pricing. It's when a business drive out competitors by charging lower prices even at a short-term loss. Competitors that can't sustain such low prices will be forced out of the market giving the surviving businesses more market share and ability to raise prices.
7. I'm Batman!!

20 - Price Controls, Subsidies, Risks of Good Intentions


1. President Richard Nixon, 1970s, 90-day price and wage freeze to fight inflation. Milton Friedman, 'One of those plausible schemes with very pleasing commencement that have shameful conclusions'.
2. Price ceiling - Maximum price for a specific good or service
3. Price floor - Minimum price in a specific market. Keeping price artificially high and not allowing price to fall to equilibrium.
4. In terms of helping consumers and producers, price controls are counter-productive. However minimum wage is a better solution.
5. Economists generally agree that rent control results in reduced quantity and quality of housing that is available.
6. A subsidy is a government payment given to individuals, organizations or businesses to offset costs to advance a specific public goal.

ToC - Elinor Ostrom vs Tragedy of the Commons ..

Free riders - people who benefit without paying
Responding to incentives - why pay more if I can get it for less?
Countered by taxes that fund institutions that are for our collective well-being (public goods)
Market failure - when markets fail to provide enough public goods
Public good - anything having the characteristics of non-exclusion (cannot exclude/disfavour people that do not pay f.ex. those who evade taxes are not exempt from national defence) and non-rivalry (one person’s consumption of the good does not ruin it for others f.ex. public parks)
If a good or service meets these two criteria, it is unlikely that private firms will produce it, no matter how essential it is - why governments are involved
Tragedy of the Commons - the idea that common goods to which everyone has access are often misused and exploited (fueled by personal incentives that disregard the commonwealth)
Environmental problems - deforestation/overfishing
Competition provides an incentive to exploit a resource before another company can, regardless of future repercussions
Finite resource thus gets pillaged
Environmental economics
Unregulated markets occasionally fail to produce the outcome society desires
Misallocation of resources due to price signals, for example
Externalities - situations when there are external costs or benefits that accrue to other people or society as a whole
Negative externality (people are made worse off)
Repercussions of factory run-off (The free market assumes that all the costs associated with producing that product are accounted for within the price of those products, but, in this case, the market is wrong) - market failure
Regulate through production quotas or chemical bans —> EPA
Positive externality (people are made better off
Education (higher income - tax revenue - etc)
Externalities are the justification for almost everything the government does (can tax factories/subsidise education)
Adjustments are made when the government is convinced the free market is not adjusting to externalities
Regulatory policies (rules established by govt decree) + market-based policies (policies designed to manipulate markets, prices, and incentives to correct market failures) can be used to fix externalities
Regulatory policies
Positive externalities of an institution can be perceived to be so high/valuable that the govt essentially commandeers the market + implying everyone should pay
Compulsory education, govt payment of schools through taxes
Market-based Policy
Taxes and subsidies
Typically preferred by economists
Instead of spending money on enforcing regulations, government is earning tax revenue that can be used for further purposes
Cap and trade
Emissions trading
Pollutions permits can be bought or sold (incentive to stop polluting and sell permit)
Both
Taxing cigarette producers and regulating where one can smoke/supports anti-smoking campaigns and restricts tobacco advertisements
In an unregulated global economy, where producers want to make products as cheaply as possible, there is an incentive to ignore environment to get ahead (Tragedy of the Commons)
