The Keurig company is interested in understanding the demand for its coffee makers. These coffee makers are sold in many different markets, each of which has its own characteristics. To estimate that demand it uses the following model: lnQuantity = β0 + β1lnPrice + β2lnIncome + β3lnCoffeeprice + β4lnStarbucks + ei
Where:
lnQuantity is the natural logarithm of the quantity sold in each market
lnPrice = the natural logarithm of the price of Keurig coffee makers,
lnIncome = the natural logarithm of income in the specific market in which the coffee maker is sold,
lnCoffeeprice = the natural logarithm of the average price of ground coffee in the market in which the coffee maker is sold.
lnStarbucks = the natural logarithm of the average price of Starbucks coffee in each market.
The estimated demand function is (p-values is parentheses): 26.332 – 0.879( lnPrice) + .0386(lnIncome) – 0.0563(lnCoffeePrice) – 0.0826(lnStarbucks). (0.00253) (0.037) (0.371) (0.0012)
What are two reasons why this model is estimated in logarithmic form.
Provide an interpretation of the estimated coefficient on the price variable.
Are the results of the estimation consistent with theory? If not identify any unexpected results.
based on the estimated value of the price coefficient should Keurig increase the price of its coffee makers, decrease the price of its coffee makers, or is there not enough information to tell?

Acquiring a company through the purchase of shares on the open market and against the will of the target company’s existing management is called a ”hostile takeover”. Such in- vestors were known as “raiders”. All this was fictionalized in the movie Wall Street, with Michael Douglas portraying the raider Gordon Gekko, who famously espoused “Greed is good.” The time was full of jocular jargon, as management could consume a “poison pill” by taking on a costly financial structure that would make it difficult to consummate a hostile takeover. In some cases, a raid could be fought against by buying a raider’s shares back at a premium; this tack became known as “greenmail,” a takeoff on blackmail. To get a gist of the strategizing that occurred between a raider and management, consider the game below:
N= {Raider,Management}
(Do not Buy),(Buy, Greenmail),(Buy, No Greenmail,Take Over), (Buy,No Greenmail,Do not Takeover) are the terminal histories.
P(∅) = Raider, P(h) = Management for non-terminal history h= {Buy}, and P(h′ ) = Raider for non-terminal history h′ = {Buy,NoGreenmail}
Preferences over the terminal histories are: (Buy,Green Mail) ≻Raider (Do Not Buy) ≻Raider (Buy, No Green Mail, Takeover) ≻Raider (Buy, No Green Mail, No Takeover)

➤ Why do entry and exit drive economic profit to zero in the long run for monopolistic competition but not for monopoly?
In monopolistic competition free entry erodes short-run profits because rival firms introduce close substitutes, shifting demand for each firm left until price equals average cost. A monopoly faces barriers to entry, so rivals cannot eliminate profits. The monopolist can sustain positive economic profit since market power and entry barriers persist.

The gross domestic product (GDP) of the United States is defined as the all in a given period of time.Based on this definition, indicate which of the following transactions will be included in (that is, directly increase) the GDP of the United States in 2022.
Scenario
2022 GDP
Included
Excluded
Bubble Brew Cafe, a U.S. boba tea company, produces a classic milk tea at its location in Manhattan on January 14, 2022. It sells the tea to a customer immediately.
Yeast Crafters, a U.S. yeast company, produces brewer’s yeast at a plant in Wisconsin on September 25, 2022. It sells the brewer’s yeast to Hoptopia Brew Works for use in the production of a new beer that will be made in the United States in 2022. (Note: Focus exclusively on whether production of the brewer’s yeast increases GDP directly, and ignore the effect of production of the new beer on GDP.)
The Federal Emergency Management Agency (FEMA) deposits funds into Mike’s checking account to help pay for his hurricane-related expenses.
Du Belgique Air, a Belgian household appliance company, produces a air fryer at a plant in New York on December 9, 2022. A chef-in-training buys the air fryer on December 24.

➤ How do I determine profit and plot profit points on the graph?
Find profit at each quantity by subtracting total cost from total revenue: Profit(Q) = TR(Q) − TC(Q). Do this for Q = 0…7 and plot the results as green triangles. The profit-maximizing quantity is where the vertical gap between TR and TC is largest; negative values indicate losses plotted below the axis.

Read Eye on FiscalStimulus. From the peak in 1929 to the Great Depression trough in 1933, government tax revenues fell by 1.9 percent of GDP and government expenditure increased by 0.3 percent. Real GDP fell by 25 percent. Compare and contrast this experience with the fiscal policy that accompanied the 2008-2009 recession. What did fiscal policy do to moderate the last recession that was largely absent during the Great Depression?
