Consider a city with three consumers: 1, 2, and 3. The city provides park land for the enjoyment of its residents. Parks are a public good, and the amount of park land (which is measured in acres) is denoted by z. The demands for park land for the three consumers are as follows:

D1 =40–z, D2 =30–z, D3 =20–z.

These formulas give the height of each consumer’s demand curve at a given level of z. Note that each demand curve cuts the horizontal axis, eventually becoming negative. For the problem to work out right, you must use this feature of the curves in deriving DΣ. In other words, don’t assume that the curves become horizontal once they hit the axis.

(a) The height of the DΣ curve at a given z is just the sum of the heights of the individual demands at that z. Using this fact, compute the expres- sion that gives the height up to the DΣ curve at each z.

(b) The cost of park land per acre, denoted by c, is 9 (like the demand intercepts, you can think of this cost as measured in thousands of dollars). Given the cost of park land, compute the socially optimal number of acres of park land in the city.

(c) Compute the level of social welfare at the optimal z. This is just the area of the surplus triangle between DΣ and the cost line.

(d) Suppose there are two other jurisdictions, each with three consum- ers, just like the given jurisdiction. Compute total social welfare in the three jurisdictions, assuming each chooses the same amount of park acres as the first jurisdiction.

(e) Now suppose the population is reorganized into three homoge- neous jurisdictions. The first has three type-1 consumers (i.e., high demanders). The second has three type-2 consumers (medium demand- ers), and the third has three type-3 consumers (low demanders). Repeat (a), (b), and (c) for each jurisdiction, finding the DΣ curve, the optimal number of park acres, and social welfare in each jurisdiction.

(f) Compute total social welfare by summing the social welfare results from (e) across jurisdictions. How does the answer compare with social welfare from (d)? On the basis of your answer, are homogeneous juris- dictions superior to the original mixed jurisdictions?

Hilton Hotel Vs Mariott Hotel

Hilton Worldwide Holdings Inc. (Hilton), a global class hotel operating out of 113 countries and
territories as of 2018, had a portfolio of 16 world class brands consisting of 5,000 properties. The
debate continues on whether Hilton can survive and thrive in the new age of travel and the
growing trend of e-commerce in the world. Hilton was able to differentiate itself from other
global hotels because of its unique employee centric HR practices like their recruitment, on
boarding, and training processes.
The leadership at Hilton believed in attracting, hiring, and retaining employees. This made
business sense because these employees would service their guests better. Over the years, the
company created a culture of high engagement of employees who went out of their way to
delight customers. Hilton employed a truly diverse workforce across a variety of positions in its
hierarchical structure ranging from valet to cleaning personnel, restaurant servers, concierge
providers, and managers which were recruited using global recruiters who were able to recruit a
large number of talented employees. The management kept its focus on the human aspect in
order to become profitable. The hotel was successful because it gave each its employee a special
work culture about caring for each other. The management felt that its continued focus on HR
policies and practices had acted as a competitive advantage for them...
Marriott, a hospitality giant, had a huge association with social media which generated a huge
response from its followers. Using a team structure and empowered self-managed teams,
Marriott was able to respond to global changes and to increase its flexibility by attracting on line
customers.

The Facebook page of Marriott attracted 1,874,121 likes and 4,041,532 visits while its Twitter
account was followed by 171,842 people as on March 2015. Its major move into gamification
came when it introduced a game on Facebook in 2011 for recruiting people, a game called ‘My
Marriott Hotel' as part of its recruitment gamification strategy on its Facebook jobs and careers
page. Mariott had earlier released a game named ‘Xplor' which gave players a virtual experience
of touring five gateway cities and solving challenges which led to their earning rewards that
could be redeemed against their stay in Marriott hotels. The company also tried its hand at
different apps like ‘Red Coat Direct', ‘Workspace on Demand', and ‘The Perfect Travel
Companion' in order to provide fast and convenient services at the customer's fingertips. Players
were then directed to Marriott's official recruiting page where they could submit their resumes
for a suitable position.

Better Mousetraps has developed a new trap. It can go into production for an initial investment in equipment of $5.4 million. The equipment will be depreciated straight-line over 6 years, but, in fact, it can be sold after 6 years for $606,000. The firm believes that working capital at each date must be maintained at a level of 10% of next year’s forecast sales. The firm estimates production costs equal to $1.70 per trap and believes that the traps can be sold for $7 each. Sales forecasts are given in the following table. The project will come to an end in 6 years, when the trap becomes technologically obsolete. The firm’s tax bracket is 40%, and the required rate of return on the project is 12%.

Suppose the firm can cut its requirements for working capital in half by using better inventory control systems. By how much will this increase project NPV? (Do not round your intermediate calculations. Enter your answer in millions rounded to 4 decimal places.)

From the historical data, the firm has determined the following transition matrix:
  

  
For example, if an account is two months overdue at the beginning of a month, there is a 40% chance that at the beginning of next month, the account will not be paid up (and therefore be three months overdue) and a 60% chance that the account will be paid up. It is assumed that after three months, a debt is either collected or written off as a bad debt. Once a debt is paid up or written off as a bad debt, the account is closed, and no further transitions occur.

What is the probability that a new account will eventually be collected?
