Speculation is often considered to be morally dubious. But, can speculation actually be useful to the market process? This video shows that speculation can actually smooth prices over time and increase welfare.
Speculators take resources from where they have low value and move them through time to where they have high value. We also take a look at speculation in the futures market — for instance, can orange juice future prices help predict Florida weather? Let’s find out.

Information and Incentives
Published on 8 Feb 2015
What does an increase in the price of oil tell us? What does it signal? And how do we adjust to that signal? The price of oil gives users of oil an incentive to respond — by using less oil or substituting lower-cost alternatives for oil.
The key here is that we let people decide how to most effectively allocate the use of goods and resources. To solve the great economic problem, we need to solve information and incentive problems.
In this video, we take a look at how Nobel Prize-winner Friedrich Hayek described the price system and its approach to solving the information problem. We’ll also continue with our example of oil to show how the price is equal to the marginal value of oil or the social opportunity cost.

The Great Economic Problem
Published on 8 Feb 2015
In this video, we discuss how different markets are linked to one another. How does the price of oil affect the price of candy bars? When the price of oil increases, it is of course more expensive to transport goods, like candy bars. But there are other, more subtle ways these two markets are connected. For instance, an increase in the price of oil leads to an increase in demand for oil substitutes, like ethanol. And when the supply of oil falls, oil should shift to higher-valued uses. But, which uses? How do we decide where to use less oil?
This brings us to the great economic problem: how to most effectively arrange our limited resources to satisfy our needs and wants. Which approach — central planning or the price system — is better at solving this problem? Join us as we explore this question further.

Markets Link the World
Published on 8 Feb 2015
In this video, we discuss how markets link people and places all over the world. We’ll take a look at production and consumption markets and, importantly, the role that prices play in it all. Following up on our example of a rose, we take a look at other global products such as the Apple iPhone. Where is the iPhone made? It’s produced by thousands of people all over the world, working in cooperation in order to make one product that many of us enjoy. Join us as we observe the invisible hand in action.

Wage Subsidies
Published on 3 Feb 2015
What’s the difference between a wage subsidy and a minimum wage? What is the cost of a wage subsidy to taxpayers? We take a look at the earned income tax credit and how it affects low-skilled workers. We also discuss Nobel Prize-winning economist Edmund Phelps’ work on wage subsidies.

Subsidies
Published on 27 Jan 2015
What is a subsidy? A subsidy is really just a negative or reverse tax. Instead of collecting money in the form of a tax, the government gives money to consumer or producers. In this video, we look at the subsidy wedge and who benefits the most from different subsidies.

Tax Revenue and Deadweight Loss
Published on 27 Jan 2015
Why do taxes exist? What are the effects of taxes? We discuss how taxes affect consumer surplus and producer surplus and discuss the concept of deadweight loss at length. We’ll also look at a real-world example of deadweight loss: taxing luxury yachts in the 1990s.

Who Pays the Tax?
Published on 27 Jan 2015
Who bears the burden of a tax? Buyers or sellers? Why is it that the more elastic side of the market pays a smaller share of a tax? Again, we’ll apply what we know to the example of Social Security taxes and also look at the health insurance mandate as a part of the Affordable Care Act. Who pays for the mandate? The employers or the workers? We’ll also look at supply and demand of labor. Is the demand for labor more elastic than the supply?

Commodity Taxes
Published on 27 Jan 2015
In this video we cover taxes and tax revenue and subsidies on goods. We discuss commodity taxes, including who pays the tax and lost gains from trade, also called deadweight loss. We’ll take a look at the tax wedge and apply what we learn to the example of Social Security taxes.

Applications Using Elasticity

In this video, we take a look at real-world applications of elasticity, using the examples of slave redemption in Sudan and and the effects of gun buyback programs in the U.S.

Elasticity and Slave Redemption
Published on 27 Jan 2015
Beginning in 1993, Sudan entered into a civil war, with one of the worst parts being that many people were kidnapped and sold into slavery. Humanitarian groups traveled to Sudan to redeem slaves by buying them out of slavery. Is this good policy? Did it work out, or make it worse? Let’s use elasticity to analyze the situation.

Elasticity of Supply
Published on 27 Jan 2015
When is a supply curve considered elastic? What are determinants of elasticity of supply? Let’s compare Picasso paintings and toothpicks. Which has an elastic or inelastic supply? For which good could you increase production at a low cost? We also go over how to calculate the elasticity of supply, including using the midpoint formula.

Calculating the Elasticity of Demand
Published on 27 Jan 2015
Elasticity of demand is equal to the percentage change of quantity demanded divided by percentage change in price. In this video, we go over specific terminology and notation, including how to use the midpoint formula. We apply elasticity of demand to the war on drugs, and more broadly to the prohibition of a good when it has an elastic demand.

Elasticity of Demand
Published on 27 Jan 2015
How much does quantity demanded change when price changes? By a lot or by a little? Elasticity can help us understand this question. This video covers determinants of elasticity such as availability of substitutes, time horizon, classification of goods, nature of goods (is it a necessity or a luxury?), and the size of the purchase relative to the consumer’s budget.

Supply and Demand Terminology
Published on 2 Jan 2015
What is the difference between a change in demand and a change in the quantity demanded? The terminology can be confusing — but we’ll provide some clarity in this video. In short, a change in demand refers to a shift in the demand curve — caused by a number of factors such as income, population, etc. A change in quantity demanded refers to a movement along a fixed demand curve — caused by a change in price.
