b. Explain what heteroscedasticity is and describe two possible causes of heteroscedasticity. Discuss the consequences of heteroscedasticity for OLS estimation.

Answers

Answer 1

Heteroscedasticity refers to the unequal variance of the error terms in a regression model. In other words, the variability of the residuals changes across the range of the independent variable(s).


Two possible causes of heteroscedasticity are:

1. Outliers: Extreme values in the dependent variable can cause heteroscedasticity. When there are a few observations with large residuals, the variance of the errors can increase. For example, in a study of housing prices, a few very expensive houses can create heteroscedasticity, since the variance of the error terms will be larger for those houses than for the rest of the sample.

2. Omitted variables: Another possible cause of heteroscedasticity is the omission of relevant variables from the regression model. If there is a variable that affects the variance of the errors, and that variable is not included in the model, heteroscedasticity can occur. For example, if we are studying the effect of education on income, and we do not include age in the model, the residuals may have a larger variance for older people than for younger people, which will cause heteroscedasticity.

The consequences of heteroscedasticity for OLS estimation are that the standard errors of the coefficients will be biased, and the t-statistics and p-values will be incorrect. As a result, we cannot trust the significance of the coefficients, and the confidence intervals may be too wide or too narrow. Heteroscedasticity can also affect the predictive accuracy of the model, since the errors may be larger for certain parts of the range of the independent variable(s). Therefore, it is important to detect and correct heteroscedasticity in regression analysis. One way to do this is by using a robust estimator, such as White's heteroscedasticity-consistent estimator, which adjusts the standard errors for heteroscedasticity. Another way is to transform the variables or use weighted least squares to correct for the unequal variance of the errors.

True or false? in the presence of a positive externality, aPigouvian subsidy is required (instead of a tax), to restore thesocially optimal level.

Answers

The given statement " in the presence of a positive externality, a Pigouvian subsidy is required (instead of a tax), to restore the socially optimal level" is True because In the presence of a positive externality, such as the benefits that come from a business investing in renewable energy sources or an individual getting vaccinated, the market fails to produce the socially optimal level of the good or service.

This is because the private benefits of the action are less than the social benefits, meaning that the decision to invest or get vaccinated does not take into account the positive impact on others.To restore the socially optimal level, a Pigouvian subsidy is required instead of a tax. A subsidy provides a monetary incentive for individuals or businesses to engage in actions that have positive externalities, thus increasing the supply of the good or service.

This results in a shift of the supply curve to the right, lowering the equilibrium price and increasing the quantity consumed. The subsidy also internalizes the positive externality by compensating those who produce the good or service for the social benefits that they create. In contrast, a tax on a positive externality would reduce the supply of the good or service, leading to a higher price and lower quantity consumed.

This would not restore the socially optimal level, as it would fail to incentivize individuals or businesses to engage in actions that produce positive externalities. Therefore, a Pigouvian subsidy is necessary to address positive externalities and achieve the socially optimal level.

The value of currencies may be either high or low. when it is thought that a currency depreciation is required to balance trade.

If imports are substantially cheaper and exports are more expensive, the currency is overvalued. Furthermore, when the economy's value in foreign exchange is low, an overvaluation means that domestic demand declines dramatically, which encourages consumers to consume more imports.

An executive in the industry told me it suffered a great deal in 2020 for four reasons. First, people had switched to comfortable clothing, such as sleepwear, caftans, and casual styles. Second, people were simply not going out as much and therefore needed fewer items of clothing. Third, companies were having a really difficult time fitting clothing on models in the COVID-19 era, which resulted in an increase in clothing returns due to improper sizing. Finally, companies were not able to do photo shoots with the new clothing. Draw these effects on the graph above, labeling the new equilibrium price p2020 and q2020. Describe in words why each curve shifted the way that it did. Ex. Demand shifted ___ because ____.

Answers

First, the shift towards comfortable clothing would cause a decrease in demand for more formal or less comfortable clothing.

This would shift the demand curve for those types of clothing to the left. As a result, the equilibrium price and quantity of those types of clothing would decrease. Second, the decrease in people going out would cause a decrease in demand for clothing overall. This would shift the demand curve for clothing to the left. As a result, the equilibrium price and quantity of clothing would decrease. Third, the difficulty in fitting clothing on models would increase the cost of producing clothing, as companies would need to spend more time and resources on adjusting sizing.

This would shift the supply curve for clothing to the left. As a result, the equilibrium price of clothing would increase, while the equilibrium quantity would decrease. Finally, the inability to do photo shoots would also increase the cost of producing clothing, as companies would need to rely on alternative methods to showcase their products. This would also shift the supply curve for clothing to the left. As a result, the equilibrium price of clothing would increase, while the equilibrium quantity would decrease.

Suppose there is an unexpected volcano explosion that destroys productive capital, so that the marginal product of capital increases at full capacity, and potential output falls. a) What would happen to current GDP in the short-run, assuming all other parameters remain the same, that is, ceteris paribus? (hint: consider the short-run IS curve) b) To help the economy, central bank decide to engage in expansionary policy by raising target inflation rate? What would happen to the AS and AD curves? c) To rebuild the loss productive facilities, the government decides to increase spending. What happens to the AS and AD curves?

Answers

a) The unexpected volcano explosion that destroys productive capital would lead to a decrease in potential output, causing a leftward shift of the short-run aggregate supply (AS) curve. This would lead to an increase in the price level and a decrease in GDP in the short-run, assuming all other parameters remain constant.

b) If the central bank engages in expansionary policy by raising the target inflation rate, this would shift the AD curve to the right, increasing output and price level in the short-run. However, the increase in inflation rate might cause a reduction in real GDP in the long-run due to higher inflation expectations.

c) If the government increases spending to rebuild the loss of productive facilities, this would shift the AD curve to the right, increasing output and price level in the short-run. However, if the government's spending is financed through higher taxes or borrowing, it might lead to higher interest rates and a reduction in private investment, potentially lowering long-run economic growth.

the faster a fluid moves, the more pressure the fluid exerts.

Answers

Fluid pressure is directly proportional to fluid velocity. This is due to the fact that when a fluid is moving faster, the kinetic energy of the particles increases.

This increased kinetic energy is then transferred through the fluid and is converted into pressure. This is known as the Bernoulli Principle, which states that pressure is dependent on the speed of the fluid. As the speed of the fluid increases, the pressure also increases. This effect is also seen in other fluids such as air, where faster moving air will have greater pressure than slower moving air.

This is why wind turbines are able to generate so much power. By having the air move faster, the pressure is increased, allowing for more energy to be generated. This is the same principle that applies to all fluids.

if you currently make $25,000 a year and the cpi rises from 110 today to 150 in five years, then you need to be making $43,333.33 in five years to have kept pace with consumer price inflation. a. true b. false

Answers

The statement is true. You need to be making $43,333.33 in five years to have kept pace with consumer price inflation.

The CPI (Consumer Price Index) is a measure of the average change in prices of goods and services over time, which indicates the rate of inflation. If the CPI rises from 110 to 150 in five years, it means that the cost of living has increased by 36.36% ([(150-110)/110] x 100) over that period.

To keep pace with inflation, your income needs to increase by the same percentage. Therefore, your income in five years needs to be:

$25,000 x (1 + 36.36%) = $34,090.91

However, this only reflects the increase in the cost of living. To maintain the same standard of living, you would need to adjust your income for both inflation and any changes in your personal circumstances or expenses. To have the same purchasing power in five years as you have today, your income needs to be:

$25,000 x (150/110) = $43,181.82.

Relative to a monopoly charging a single price to all consumers, perfect price discrimination ______ producer surplus and ______ consumer surplus. A. increases; decreases B. increases; increases C. decreases; decreases D. decreases; increases

Answers

Relative to a monopoly charging a single price to all consumers, perfect price discrimination increases producer surplus and decreases consumer surplus.

Perfect price discrimination occurs when a monopoly charges each individual consumer their maximum willingness to pay for a good or service. This means that the monopoly captures all of the consumer surplus for themselves, resulting in an increase in producer surplus.

However, since each consumer is being charged their maximum willingness to pay, they are not receiving any surplus, resulting in a decrease in consumer surplus. This can also lead to some consumers being priced out of the market altogether, as the monopoly may charge prices that are too high for certain individuals.

Overall, perfect price discrimination can result in a more efficient allocation of resources as the monopoly is able to maximize profits, but it can also lead to a decrease in overall welfare as consumers are not receiving any surplus.

How did a decline in housing prices help trigger the subprimefinancial crisis starting in​ 2007?

Answers

A decline in housing prices helped trigger the subprime financial crisis starting in 2007 by causing many homeowners to owe more on their homes than the homes were worth, leading to defaults and foreclosures on subprime mortgages.

This led to a decrease in the value of mortgage-backed securities and the collapse of many financial institutions heavily invested in these securities. The decline in housing prices was triggered by a combination of factors including an oversupply of housing, relaxed lending standards, and speculation in the housing market.

As interest rates increased, many borrowers were unable to make their mortgage payments, leading to a rise in defaults and foreclosures. This, in turn, led to a decrease in housing prices, causing more homeowners to owe more on their homes than they were worth, and resulting in a downward spiral that ultimately triggered the subprime financial crisis.

In summary, the decline in housing prices played a significant role in the subprime financial crisis by causing a wave of defaults and foreclosures on subprime mortgages, decreasing the value of mortgage-backed securities, and ultimately leading to the collapse of many financial institutions.

Answers

A nominal interest rate of approximately 34.22% is necessary for you to earn a 27% real interest rate on your investment with a 5.7% inflation rate.

To calculate the nominal interest rate necessary to earn a 27% real interest rate when the rate of inflation is 5.7%, we can use the Fisher equation:

(1 + nominal interest rate) = (1 + real interest rate) x (1 + inflation rate)

Let's plug in the given values and solve for the nominal interest rate:

(1 + nominal interest rate) = (1 + 0.27) x (1 + 0.057)

(1 + nominal interest rate) = 1.27 x 1.057

1 + nominal interest rate = 1.34219

nominal interest rate = 1.34219 - 1

nominal interest rate = 0.34219

To express the nominal interest rate as a percentage, multiply by 100:

If the income elasticity of money demand is 3/4 and income increases 8%, by about how much does the price level change, where nominal money supply remains the same?
a. Rises by 6%.
b. Unchanged.
c. Rises by 8%.
d. Falls by 6%

Answers

When nominal money supply remains the same, the price level (d) falls by 6%.

If the income elasticity of money demand is 3/4, and income increases by 8%, we can calculate the change in money demand by multiplying the income elasticity by the change in income: (3/4) * 8% = 6%. This means that the demand for money increases by 6%.

However, the nominal money supply remains the same, which implies that the central bank has not adjusted the money supply to accommodate the increased demand for money. In this situation, the price level will need to adjust to bring the money market back to equilibrium.

Since the money supply is fixed, and the demand for money has increased, the price level must decrease for the quantity of money demanded to equal the quantity of money supplied. Therefore, the price level falls by 6%. The correct answer is d. Falls by 6%.

if the seller has made a substantial beginning in manufacturing custom-ordered goods, then an oral contract may be enforceable regardless of the amount of money involved in the contract. T/F

Answers

True. If the seller has made a substantial beginning in manufacturing custom-ordered goods, then an oral contract may be enforceable regardless of the amount of money involved in the contract.

The statute of frauds is a legal principle that requires certain types of contracts to be in writing in order to be enforceable.

These types of contracts typically include contracts for the sale of goods over a certain value, contracts for the transfer of real property, contracts that cannot be performed within one year, and contracts for the sale of securities, among others.

However, the "substantial beginning" doctrine is an exception to the statute of frauds for contracts involving custom-ordered goods.

Under the "substantial beginning" doctrine, if a seller has made a significant amount of progress or investment in manufacturing custom-ordered goods before the contract is reduced to writing, an oral contract for the sale of those goods may be enforceable, even if it does not meet the usual requirement of being in writing.

The rationale behind this doctrine is that the seller's performance, in the form of making a substantial beginning in manufacturing the goods, demonstrates a level of commitment and reliance on the contract that is equivalent to a written agreement.

It's important to note that the threshold for what constitutes a "substantial beginning" may vary depending on the specific jurisdiction and circumstances of the case.

Courts may consider factors such as the extent of the seller's investment, the progress made in manufacturing the goods, and the degree of customization involved.

However, generally, the seller's performance must be significant and demonstrate a clear intent to perform the contract.

First, the territories were seen as temporary and not worth investing a lot of resources in. Second, the federal government was focused on other priorities, such as Reconstruction after the Civil War and industrialization in the East. Third, corruption and scandal were often tied to powerful political interests, making it difficult for the federal government to effectively intervene. Fourth, the government officials responsible for overseeing the territories were often corrupt themselves, making it difficult to root out corruption from within.

Additionally, the sheer size and complexity of the western territories made it difficult for the federal government to effectively govern them from a distance. Many of the territories were vast and sparsely populated, with limited infrastructure and communication systems.

The decile ratio of a country decreased over two years, but itsGini coefficient increased over the same period. What does thismean?

Answers

The decile ratio and Gini coefficient are two common measures of income inequality.

The decile ratio measures the difference between the income of the top 10% and the bottom 10% of earners in a country. A decrease in the decile ratio means that the income gap between the richest and poorest segments of society has narrowed.

On the other hand, the Gini coefficient measures the overall inequality in a country's income distribution. An increase in the Gini coefficient means that income inequality has worsened across the entire population.

Therefore, if the decile ratio of a country decreased over two years but its Gini coefficient increased over the same period, it suggests that while the income gap between the richest and poorest has narrowed, overall income inequality has worsened. This could happen, for example, if the middle class experienced a decrease in their income, which would result in a narrowing of the decile ratio, but at the same time, the rich got much richer, pushing up the overall Gini coefficient.

It is important to note that while these measures are useful for understanding income inequality, they do not tell the whole story. Other factors such as access to education, healthcare, and social safety nets also play a role in determining overall well-being and opportunity in a society.

the table below shows a monopolist's demand curve and the cost information for the production of its good. what will its maximum profit be? quantity price per unit total cost 10 $100 $100 20 $80 $400 30 $60 $800 40 $40 $1,400 50 $20 $2,400 responses $1,600 $1,600 $1,200 $1,200 $1,000

Answers

The maximum profit a monopolist can make is determined by the difference between its total revenue and total cost.

The total revenue of the monopolist is calculated by multiplying the price per unit with the quantity of units produced. In this case, the total revenue of the monopolist is $2,000 (10 x $100 + 20 x $80 + 30 x $60 + 40 x $40 + 50 x $20).

The total cost of the monopolist is $2,400 (10 x $100 + 20 x $400 + 30 x $800 + 40 x $1,400 + 50 x $2,400). The difference between the total revenue and total cost is -$400, which means the maximum profit that the monopolist can make is $1,600. The monopolist should produce only 30 units to maximize its profit as the total cost for producing 30 units is $800, which is the lowest.

Answers

The founding Fathers held a Constitutional Convention to discuss and rewrite the laws that would be fair and just for the nation.

The Constitutional Convention was held in Philadelphia, Pennsylvania, in 1787, and was attended by delegates from 12 of the 13 states that were part of the United States at that time. The purpose of the convention was to revise the Articles of Confederation, which had created a weak central government and limited the power of the federal government. Instead, the delegates decided to draft a new constitution that would establish a stronger federal government and provide a framework for the operation of the three branches of government: the legislative, executive, and judicial branches. The resulting Constitution of the United States is still the supreme law of the land and has been amended 27 times to reflect changes in society and the needs of the country.

The top of the business cycle is known as thea. contractionb. troughc. expansiond. Peak

Answers

The top of the business cycle is known as the "peak." The "business cycle" is a term used to describe the fluctuations in economic activity that an economy experiences over a period of time. It consists of four main phases: expansion, peak, contraction, and trough.

During the expansion phase, the economy experiences growth in output, employment, and income. This phase can last for several years and is characterized by a general increase in economic activity. The peak is the highest point of the business cycle, where economic activity reaches its maximum level. At this point, the economy is operating at or near its full capacity. Following the peak, the economy enters the contraction phase, where economic activity starts to decline. This phase can be marked by a decrease in output, employment, and income. Eventually, the contraction phase leads to the trough, which is the lowest point of the business cycle. It is at this point that the economy starts to recover and begins a new expansion phase.
In summary, the top of the business cycle is referred to as the "peak," which is the point at which economic activity is at its highest level before entering a contraction phase.

________ refers to the concept that a manager will only investigate budget variances that are relatively large.

Answers

Materiality refers to the concept that a manager will only investigate budget variances that are relatively large.

Materiality is a concept in accounting and management that refers to the relative size or significance of a budget variance. Materiality determines whether a manager will investigate a budget variance or not.

If a variance is material, meaning it is relatively large, then the manager is likely to investigate it to determine its cause and whether corrective action is necessary. On the other hand, if a variance is immaterial, meaning it is relatively small, then the manager may choose not to investigate it further.

The concept of materiality is essential in budgeting and financial reporting because it helps managers to focus on significant variances that can have a material impact on the organization's financial performance.

By investigating material variances, managers can identify potential problems or opportunities and take appropriate action to address them. However, investigating every variance, regardless of its size, can be time-consuming and costly, and may not be a good use of resources.

Therefore, materiality helps managers to prioritize their efforts and resources on issues that matter the most to the organization's financial health and success.
