Study Notes

Deadweight Loss

Deadweight loss — the difference between the highest economic surplus and the actual level of surplus
Calculated by economic surplus at efficient quantity minus the actual economic surplus
Economic surplus and deadweight loss focus on marginal benefits and costs
Can happen when there is an underproduction preventing them from reaching their efficient quantity, but it can also happen when too much is produced in the market
Deadweight loss looks like in graphs like an arrowhead that points towards the market efficiency
When tip is pointed right, when its a result of underproduction. Some simply, poorly paid bureaucrat don’t have an incentive to work or make the best decisions.

Market Failure vs Government Failure

Market failure is extremely common. This creates room for the argument of government intervention as they well-designed market failures can correct market failures and lead to a more efficient outcome
Government failure limits the extent to which we should rely on government intervention
Government failure — when government policies lead to worse outcomes. This often arises when politicians and bureaucrats don’t make choices that are in the publics interest.
Politicians are often motivated by policies that will get them reelected, rather that improving efficiency or equality. They’ll choose whats popular for voters and those they receive donations from.
This happens in non-democratic countries too, as those with dictatorships or monarchies do not have to worry about reelection. This causes them to be able to pass policies that enrich themselves but no one else.
Likewise, bureaucrats face incentives that drive them to do things that are not in the publics interest. If agencies want to expand their empires, they will wind up created a bloated bureaucracy that fails to provide efficient services. Or some are too friendly with those they regulate and they begin to act in the interests of those instead of the broader public. Most markets are dominated by only a handful of companies.
Sellers exploit limited competition by charging higher prices, leading consumers to buying a smaller quantity. This results in an underproduction since they’re not producing at their efficient quantity.

Externalities

Externalities arise whenever the choices that buyers and sellers make have side effects on others.
Many utilities generate electricity from burning coal, which contributes to pollution that effects you and others, even if you don’t buy or sell coal
When suppliers don’t take account of the side effects produced, they’ll produce more coal than whats in societies interest. Generally, producers will supply a higher quantity than efficient with side effects.
Externalities aren’t always negative.
Making the choice to get the COVID-19 vaccine is a decision you make, which has the side effect of protecting you and others from the infection of the virus

Information Problems

Private information occurs when you’re worried that the people you’re doing business with know something that you don’t.
If the sellers knows more about the car than you do, you may question why they’re selling it for such a low price.
This leads to people to buy or sell less than the efficient qauntity.

Irrationality

Irrationality occurs when people make decisions that aren’t in their best interests.
If buyers and sellers aren’t using the rational rule, they will not consider their marginal benefits/costs and thus not meet efficient allocation/production

Government Forces

Taxes or quotas impede on the market being able to reach its market efficiency.
Sometimes these are done to fix some of the aforementioned failures, but they often create their own distortions that drive the market from its efficiency.

Beyond Economic Efficiency

Before deciding to evaluate an economic policy on efficiency grounds, make sure you reference the following critiques:
Economic efficiency focuses on economic surplus, regardless of who it goes to but some people believe distribution of the benefit also matters
Most economists look beyond efficiency and consider distributional consequences, and assess whether that outcome seems fair and equitable.
Distributional consequences — who gets what.
How much you’re willing to pay often reflects your ability to pay and not just your marginal benefits.
If someone has a higher income and can thus have a higher willingness to pay for an item, that doesn’t mean their marginal benefit will be as significant as someone will a lower income and willingness.
Economic efficiency is about the outcome, but people often care about the process too.
If you make an item, do you deserve a higher portion of that item? If everyone can make an item, then why should it be shared if you make it? Were the portions democratic or dictatorial?

Quantity Matters More Than Price

Quantities matter more than price in terms of DWL.
This happens because it measures the loss as a result of the quantity being produced being more/less than equilibrium.
After this is had been determined does price matter as it redistributes the economic surplus.
If its pointing left, its a result of overproduction.
