Consider the following hypothetical natural experiment. The United States imposes a 25% tariff on imported automobiles (cars) in 2020 but does not do so on imported trucks. Canada does not impose such a tariff. In 2020 vehicles (cars+light trucks) in the U. S. (noncommercial) averaged 30 mpg while vehicles in Canada averaged 35 mpg. In 2025 vehicles in the US averaged 35 mpg while vehicles in Canada averaged 45 miles per gallon. Assume (this is a hypothetical natural experiment) that there are no differences between drivers and economic conditions in Canada and the U.S. In an actual analysis of such a situation any observable differences would be addressed using some matching algorithm. a. Using the difference in difference estimator calculate the yearly impact of the tariff on fuel efficiency for all vehicles. b. Assuming that there were 10 million vehicle (car and light truck) sales in the U.S. in 2025 and that each vehicle drives on average 10,000 miles per year, how much more gasoline would be consumed by U. S. drivers in 2025 due to the tariff?

It is believed that the design of appurtenances in the stilling basin can reduce the basin length by 70- 80%. Give comments on this statement. This question is open-ended. Therefore it must be supported by relevant literature.

In Python:

Define a function drawCircle. This function should expect a Turtle object, the coordinates of the circle’s center point, and the circle’s radius as arguments. This function should draw the specified circle. The algorithm should draw the circle’s circumference by turning 3 degree and moving a given distance 120 times. Calculate the distance moved with the formula 2.0*π*radius/120.0.

I need the NPV of this project. Tax Rate is 40% and the WACC is 11.49%

This project requires an initial investment of $2,000,000 in equipment which will cost an additional $250,000 to install. The firm will use the attached MACRS depreciation schedule to expense this equipment. Once the equipment is installed, the company will need to increase net working capital by $100,000. The project will last 6 years at which time the market value for the equipment will be $30,000.

The project will project a product with a sales price of $120.00 per unit and the variable cost per unit will be $65.00. The fixed costs would be $500,000 per year. Because this project is very different to current products sold by the business, management has imposed a 2 percentage point premium above its current WACC as the valuation hurdle it must meet or surpass.

Years 2014 2015 2016 2017 2018 2019 Forecasted Units Sold 21,000 55,000 44,000 28,000 25,000 11,000

Pricing and demand will be taken as exogenously determined. Your goal is to efficiently use the inputs. This starts with what might be termed the short short-run, where all inputs are fixed, but they can be reallocated to different purposes. It then moves to the short-run, where some inputs (e.g., labor) is variable, but other inputs (e.g., capital) are fixed. It concludes with the long-run, where all inputs are variable.

Part A: The ‘short short-run’

The 4-A clinic consists of four workers (Sam, Ann, Trey, and Lina) who share some or all of the following tasks: performing a medical procedure, follow-ups, and tests. The data below gives their time per task, in minutes. Assume that each can work up to six hours per day (e.g., 360 minutes) at these tasks, but no more. ‘N/A’ means that the individual isn’t qualified to perform the medical procedure.

Each patient seen will ultimately need one medical procedure, two routine follow- ups, and three routine tests.

1. Calculate the number of ‘patient-equivalents’ that can be handled during a workday. If you have 4 medical procedures, 8 follow-ups, and 12 tests, that counts as four patient-equivalents, so your answer would be 4. In solving for this, you must use whole numbers; no partial patients are allowed. Some staff may be partially idle. You are reporting the aggregate for the four workers. Your score on this question will be based on how close you are to the correct answer without going over.

Reallocating the labor:

2. If each worker is assigned to tasks so that total group output is maximized, how many ‘patient equivalents’ can be seen per day? Use whole numbers when assigning tasks. Your score on this question will be based on how close you are to the maximum possible number of patients. Setting this up in Excel to keep track of total patients and minutes used is highly recommended. You will want to use the concept of comparative advantage.

What is the difference between Capitalism, Socialism, Communism, and Trade Unionism?

A small entrepreneurial company is trying to decide between developing two different products that they believe they can sell to two potential companies, one large and one small. If they develop Product A, they have a 50% chance of selling it to the large company with annual purchases of about 20,000 units. If the large company won't purchase it, then they think they have an 80% chance of placing it with a smaller company, with sales of 15,000 units. On the other hand if they develop Product B, they feel they have a 40% chance of selling it to the large company, resulting in annual sales of about 17,000 units. If the large company doesn't buy it, they have a 60% chance of selling it to the small company with sales of 20,000 units.

A cross-country pipeline transports crude oil at a rate of 500,000 barrels per day. The pressure of the oil leaving Pumping Station A is 500 psig. The pressure at the inlet of Pumping Station B is 75 psig. Station B is at an elevation 157 feet higher than Station A. Given the crude oil density is 48.0 lbm/ft3 and one barrel is equivalent to 42 gallons, determine (a) the work loss (ft∙lbf /lbm) between A and B and (b) the equivalent power consumed in the process (horsepower).
