Question 1
The model of perfectly competitive markets relies on these four core assumptions:
There must be numerous small firms and customers — each player’s actions have no effect on price and thus trade is not possible to influence the market price.
Firms must produce a homogeneous product — buyers must regard all sellers’ products as equivalent.
Firms and resources must be fully mobile, allowing for free entry into and exit from the industry.
Each firm and each customer is well informed about available products and prices.
The first two conditions imply that all consumers and firms are price takers. While the third is not strictly necessary for price-taking, a market cannot maintain competition in the long run without free entry.
Identify whether or not each of the following scenarios describes a perfectly competitive market, along with the corresponding reasons:
Dozens of companies produce plain white socks. Consumers regard plain white socks as homogeneous and don’t care which company makes them.
Several stores in the mall sell hooded sweatshirts. Each store’s sweatshirts reflect the style of that particular store; some use more cotton than others, which is reflected in the apparel’s prices.
The government has granted a patent to a pharmaceutical company for an experimental AIDS drug. That company is the exclusive producer of the drug.
In a small town, there are two providers of broadband internet access: a cable company and the phone company. The service is of the same speed.

➤ What are the direct effects of tariffs?
Tariffs raise the domestic price of imported goods, which increases domestic production compared to free trade but results in higher consumer prices. They misallocate resources toward less efficient domestic industries, harm efficient foreign producers, and generate revenue for the government imposing the tariff, reducing overall welfare versus free trade. -

Part 1
The law of demand is the assertion that
Part 2
A. the quantity demanded of a product is inversely related to its price.
B. the quantity demanded of a product is directly related to its price.
C. changes in price and changes in quantity demanded move in the same direction.
D. the demand for a product is negatively related to its price.
Part 3
An increase in the price of a product causes a decrease in quantity demanded because of the income and substitution effects. More specifically,
A. the substitution effect is the decrease in quantity demanded because the product is more expensive relative to other goods and the income effect is the decrease in quantity demanded owing to the decline in consumers’ purchasing power.
B. the substitution effect is the decrease in quantity demanded because consumer tastes have changed and the income effect is the decrease in quantity demanded because consumer incomes have fallen.
C. the substitution effect is the decrease in quantity demanded because the consumers’ purchasing power is reduced and the income effect is the decrease in quantity demanded owing to the fact that the product is more expensive relative to other goods.
D. the substitution effect is the decrease in quantity demanded because there are fewer consumers and the income effect is the decrease in quantity demanded because consumer incomes failed to increase. -

Week 1 News Analysis: Border Security Tradeoffs
Suppose the first bill that is introduced mandates that security be improved so that the probability of catching a terrorist at the border increases from 10% to 15%. Assuming the security bill does not change the position of the blue curve, place the gray point (star symbol) on the graph to show the effects of such a bill. (Hint: Be sure to plot your point on one of the black plus symbols.)
The opportunity cost of this increase in security is ◻ million visitors per year.
Suppose the first bill is passed, raising the probability of catching any given terrorist from 10% to 15%. However, this isn’t enough for some lawmakers. One representative introduces a bill that would increase security by an additional 15 percentage points.
Again, assume these measures do not change the position of the blue curve. The opportunity cost of this additional measure is ◻ million additional visitors per year.
Refer back to your previous answers. The opportunity cost of increasing the probability of catching a terrorist from 15% to 30% is ◻ the opportunity cost of increasing that probability from 10% to 15%. -

23-4 The Dangers of High Debt
Suppose that, for good or bad reasons, large deficits have led to a high debt ratio. What should the government do then? Simply trying to stablize the debt at this high level is unwise: The lesson from history is that high debt can lead to viclous cycles and makes the conduct of fiscal policy extremely difficult. Let’s look at this more closely.
High Debt, Default Risk, and Vicious Cycles
Return to equation (23.5):
BiYi-Bi-1Yi-1=(r-g)Bi-1Yi-1 (Gi-Ti)Yi
Take a country with a high debt ratio, say, 100%. Suppose the real interest rate is 3% and the growth rate is 2%. The first term on the right is (3%-2%) times 100%=1% of GDP. Suppose further that the government is running a primary surplus of 1%, thus just enough to keep the debt ratio constant (the right side of the equation equals (3%-2%) times 100% (-1%)=0%.
(Now suppose financial investors start to worry, that the government my not be able to fully repay the debit They ask tor a higher interest rate, to compensute for what they perceive as ahigher risk of defaily on the debt. But this in turn makes it more difficult for the government to stabilize the debt, Suppose, for example, that the interest nate increases from 3% to say, 8%. Then, fust to stablize the debt, the government now needs to run a primary surplus of 6% (the right side of the equation is then equal to -

Use the real business cycle model to explain the business cycles.
This model assumes that persistent total factor productivity increases, can produce expansions.

Use the graphs of the labor, output, and money markets to show how a persistent TFP shock increase produces an expansion for exogenous monetary policy behavior.

Suppose that during the past year, the price of a virtual reality headset fell from $5,500 to $5,300. During the same time period, consumer sales increased from 489,000 to 635,000 headsets.
Calculate the elasticity of demand between these two price-quantity combinations by using the following steps. After each step, complete the relevant part of the table with the appropriate answers. (Note: For decreases in price or quantity, enter values in the Change column with a minus sigh.)
Original
New
Average
Change
Percentage Change
Quantity
Price
Step 1: FiW in the appropriate values for original quantity, new quantity, original price, and new price.
Step 2: Calculate the average quantity by adding the original quantily and the new quantity, and then dividing by two. Do the same for the average price.
Step 3: Calculate the change in quantity by subtracting the ariginal quantity from the new quanbity. Do the same for the change in price.
Step 4: Calculate the percentage change in quantily demanded by dividing the change in quantity by the average quantity. Do the same to calculate the percentage change in price.
Step 5: Calculate the price elasticity of demand by dividing the percentage change in quantity demanded by the percentage change in price, ignoving the negative sign,Using the midpoint method, the elesticity of demand for heodsets is about ◻ .
