• Policymakers can respond to the inefficiency of
monopoly behavior in four ways. They can use
the antitrust laws to try to make the industry more

1Practice with simple calculations related to Fiscal Polic.docxeugeniadean34240

Practice with simple calculations related to Fiscal Policy:
Question 1: According to Paul Krugman, the complex multiplier for the United States is about equal to 2. The American Recovery and Reinvestment Act of 2009 earmarked $787B in deficit spending, of which $330.4B was spent in 2009. (Total government deficits for 2009 were $1251.7B.) The increase in nominal GDP from 2009 to 2010 was $541.2B (3.8%). If we assume that this growth resulted from the ARRA stimulus package, what was the implied multiplier associated with the stimulus package?
Question 2: Look at disposable income, personal consumption and personal savings. What was the personal savings rate in the United States in 2011? (Use savings/disposable income, i.e. Average Propensity to Save.)
Question 3: What proportion of GDP was our federal government sector in 2010? (Divide federal government spending by GDP.) Per dollar of government spending, how much government spending was financed by government debt (negative savings) in 2010 at the federal level? (Divide negative federal government savings by federal government expenditure.)
Question 41: One popularly reported statistic for national economies is the Debt/GDP ratio. Total US Federal Debt in 2010 was $13.562 Trillion. What was our Debt/GDP ratio in 2010?
Question 5: Refer to Graph Set #2, the first picture entitled “Eurostat News Release.” How does the EU compare in the size of its public sector? (What percentage of GDP is government spending?) Are its government deficits larger or smaller than those of the US as a percentage of GDP in 2009?
Question 6: Government stimulus can take the form of increased spending or reduced taxes, or both. It creates government debt in both cases, but that debt affects the larger economy by different pathways. Can you answer each the following questions in one short sentence?
· The government increases spending without increasing taxes, and a deficit is generated:
· Where does the money to finance the deficit come from?
· How does this affect affordable credit for Investment and Consumption?
· How does it affect National Incomes? Who is the government paying money to when they make an expenditure?
· The government decreases taxes without decreasing spending, and a deficit is generated:
· Where does the money to finance the deficit come from?
· How does this affect affordable credit for Investment and Consumption?
· How does it affect personal savings rates (if personal taxes are lower)? How does it affect business savings rates, i.e. retained earnings, if profits taxes are lowered? How does it affect the cost of borrowed funds for businesses?
Monte-Carlo Option Pricing
This exercise uses observation that an option price can be calculated as a discounted risk-neutral expectation.
Context
This observation suggests that we could value an option by sampling many thousands, say, of possible asset prices, at , calculating the payoffs, taking their expected value and discounting th.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Economics 2 final examination
1. Economics-2 Final Examination
PART-A
Question-1 : Describe the difference between marginal cost and average total cost. Why are both of
these costs important to a profit-maximizing firm?
Question-2: Assume that a local bank sells two services, checking accounts and ATM card services. Mr.
Donethat is willing to pay $8 a month for the bank to service his checking account and $10 a month for
unlimited use of his ATM card. Ms. Beenthere is willing to pay only $5 for a checking account, but is
willing to pay $15 for unlimited use of her ATM card. Assume that the bank can provide each of these
services at zero marginal cost.
A. If the bank is unable to use tying, what is the profit-maximizing price to charge for a checking
account?
B. If the bank is unable to use tying, what is the profit-maximizing price to charge for unlimited use of an
ATM card?
C. If the bank is able to use tying to price checking account and ATM service, what is the profit-maximizing
price to charge for the “tied” good?
D. How much additional profit does the bank make when it switches to use of a tying strategy to price
checking account and ATM service?
E. How much total surplus is generated from using tying to price the checking account and ATM service?
How does that compare to the nontied pricing strategy? Which strategy has the largest deadweight
loss?
Question-3: Describe a government created monopoly. Why might one be created? Give an example.
PART-II
Question-1: The consumption of alcohol is often cited as an example of a negative externality. Explain a
situation in which the consumption of alcohol would be considered to be a negative externality.
Question-2: Identify each of the following goods as a private good, a common resource, a natural
monopoly, or a public good, according to the classification presented in your textbook.
A. A shared apartment
B. A national monument
C. Cable TV
2. Question-3: Explain the role of opportunity cost in differentiating between economic profits and
accounting profits.
Question-4: Let’s assume that a monopolist decides to maximize revenue rather than profit. How does
this operating objective change the size of the deadweight loss? If you’re a “benevolent” manager of a
monopoly firm and are interested in reducing the deadweight loss of monopoly, should you maximize
profits or maximize revenue? Carefully explain your answer.
Question-5: Professional organizations (such as the American Medical Association and the American Bar
Association) have actively advocated regulation to restrict the right of professionals to advertise.
Describe the economic incentives that might exist for incumbent professionals to restrict advertising.
Question-6: Joe Kelp owns a commercial fishing fleet, and hires a captain for each boat in his fleet. These
workers are considered to be part of the crew. In the market for fresh Pacific salmon, Joe is one of
thousands of fishermen. Although Joe usually catches a significant number of fish each year, his
contribution to the entire salmon harvet is negligible relative to the size of the market. Joe is considered
to be a perfect competitor in the output market. If so, explain why his demand curve for labor (crew
workers) is downward-sloping, and his supply curve for labor is perfectly elastic at the market wage.
Question-7: Describe the role that diminishing marginal utility plays in the utilitarian argument for
redistribution of income.
Question-8: Describe the purpose of antitrust laws. What do they accomplish?
Question-9: What is the effective marginal tax rate of a government antipoverty program that
guarantees every family a minimum income? Explain. Why might trying several antipoverty benefits to
income level lead to an effective marginal tax rate of greater than 100 percent?
Question-10: Explain the difference between inferior goods and normal goods. As a developing economy
experiences increases in income (measured by GDP), what do you predict will happen to the demand for
inferior goods?
