The Sum of probabilities of any set of mutually exclusive and exhaustive events is…
Equal to 1
Define Panel Data
Consist of observations through time on one or more variable for multiple observational units
Define Time Series Data
Sequence of observed data for a single observatory unit of a specific variable collected over time and at discrete equally space interval of time. Ex. Daily,weekly,monthly,annually, or quarterly
Define cross-sectional data
list of observations of a specific variable from multiple observational units at a given point in time
Bar Chart
Provides a snapshot to show comparisons in between categories of data
Line Chart
Best for making comparisons over time. Used to visualized ordered observations
Histogram
Best to display distributions of data, not comparisons amongst categorical data
If the reduction of a product’s price increases total revenue, demand is best described as:
Elastic. A product’s demand is elastic if demand increases by a greater percentage than the percentage price change when prices are reduced. For example, if a 1 percent price reduction increases the quantity sold by more than 1 percent, total revenue increases and demand is said to be elastic.
Which of the following factors is most likely to lead to economies of scale? 1. Supply constraints
2. Duplication of product lines
3. Specialization by workers
- Specialization by workers. can increase their proficiency, leading to lower average costs when the firm is large enough to allow specialization.
What does price elasticity of demand depend on?
depends on the length of time within which the demand schedule is being considered.
A firm in an oligopoly market most likely faces a kinked demand curve because competitors do not match:
Price increases. “[t]he most common pricing strategy assumption in these [oligopoly] price war markets is that competitors will match a price reduction and ignore a price increase. … This oligopolistic pricing strategy results in a kinked demand curve, with the two segments representing the different competitor reactions to price changes.”
A recessionary gap:
- occurs due to a vertical long-run aggregate supply curve.
- is the amount by which actual GDP falls below potential GDP.
- occurs due to a rightward shift in the aggregate demand curve.
B. Is the amount by which actual GDP falls below potential GDP
Which of the following is least likely to affect the growth of the economy?
1. The workforce attending an average of 20 hours of training per year
2. When capital depreciation exceeds gross investment within the economy
3. An increase in the labor force that is offset by a decrease in the average hours worked per worker, making the total hours worked unchanged
- An increase in the labor force that is offset by a decrease in the average hours worked per worker, making the total hours worked unchanged
In the recovery phase of the business cycle, the economy is most likely:
- enjoying an upswing and a positive output gap opens.
- going through a trough and a 3. positive output gap opens.
going through a trough and a negative output gap starts to narrow.
- Going through a through and a negative output gap starts to narrow. Economic activity, including consumer and business spending, is below potential but is starting to increase, closing the negative output gap.”
In a fractional reserve banking system, the reserve requirement is:
- equal to the money multiplier.
- the fraction of deposits that may be lent out.
- inversely correlated with potential money creation.
inversely correlated with potential money creation.
ew deposit/Reserve requirement = €100/0.10 = €1,000.” This formula shows that if the reserve requirement is increased, money creation will decrease, thereby exhibiting an inverse relationship.
Role of a central bank in the economy

Assume that a central bank has decided to lower interest rates in the economy. To carry out this policy, the central bank will most likely:
increase required reserve requirements.
buy securities.
sell securities.
