The supply and demand for labor

For each event described below: (1) State whether the demand or the supply of labor will change, (2) Explain why the supply or demand for labor changed, (3) State what happens to the equilibrium wage and quantity of labor employed in the market. (4) Illustrate your answer with a graph. Assume that the market is perfectly competitive with a market wage of $20 per hour. Assume that each event occurs independently.

1. The demand for new housing increases as more people move into the community.
2. Changes in societal attitudes lead to more women wanting to work in construction.
3. Improved training makes construction workers more productive.
4. New technology allows much of the framing used in housing construction to be built by robots at a factory and then shipped to construction sites.
5. Construction workers unionize. The union is successful increasing wages above the equilibrium wage to $25 per hour.

Whether you agree or disagree with the concept of global warming, one thing is clear....the oceans are becoming more acidic with time. Although the changes in pH are small in number, it is enough change to have a detremental effect on the coral systems living within the ocean (as remember pH operates on a logarithm). In many real world applications, as with the coral systems in the ocean, small changes in pH can cause death. However, some of these systems have built in buffer mechanisms to maintain pH in cases where it could be deadly in cases of very small changes.

In this week's discussion:

A) Describe the term pH and and the pH scale briefly.

B) Describe the chemistry behind a physiological buffer system.

C) Describe a scenario (other than the oceans and blood) where small changes in pH are critical and whether that described system has a buffer mechanism.

An airport is located next to a large tract of land owned by a housing developer. The
developer would like to build houses on this land, but noise from the airport reduces the
value of the land. The more planes that fly, the lower is the amount of profits that the
developer makes. Let X be the number of planes that fly per day and let Y be the number of
houses that the developer builds. The airport’s total profits are 48X−X2

, and the developer’s

total profits are 60Y −Y2−XY.
A. Suppose the airport and developer act independently of each other. How many
planes will fly every day and how many houses will be built? Find the profits of the
airport and developer.
B. Suppose that a single firm bought the developer’s land and the airport. What would
be the optimal numbers of planes and houses? What is the total profit?
C. Which of the two outcomes (parts A and B) is socially optimal? Why? Explain.

Method. Ion-selective electrodes (ISEs) exist for many common anions and cations, and can be purchased from various manufacturers. They can then be connected to any voltmeter or pH meter with mV display and calibrated with appropriate standard solutions of that ion. The fluoride electrode is a solid-state membrane electrode composed of lanthanum fluoride (LaF3). The potential difference that is created across this membrane is logarithmically related to the concentration of the fluoride ion. In a combination electrode system, the reference electrode is built into the probe, and is similar in concept to the pH combination electrode. The reference electrodes (inside probe) are either Ag/AgCl or Hg/Hg2Cl2 (calomel) electrodes.

Hypothesize the chemical equilibrium that exists for fluoride at the interface of the electrode membrane surface and the analyte solution. Hint: read the above method section to identify what the membrane is constructed of. Then write the solubility equilibrium that exists for this compound. This equilibrium occurs stepwise, and only the first step applies.

1. If a dependent variable Y and independent variable X have a positive correlation, what can we predict about the sign of the slope coefficient between X and Y in a simple regression? How about in a multiple regression?

2. What would you suspect if your multiple regression t-statistics were all insignificant but the F-statistic was significant?

3. Suppose you built a 95% confidence interval around a simple regression slope coefficient and got a lower bound of 5 and an upper bound of 10. Interpret the confidence interval.

4. Suppose you wanted to know whether one categorical variable is associated with another and did a hypothesis test to see whether the proportions in a chosen category of one variable are the same for the two levels of the other variable. What two other methods could you use to see whether there is association between the variables?

A water tower is being used to provide water to a subdivision. To ensure that it provides sufficient water pressure for the homes, fire hydrants, etc., it is built on top of a hill that, at an elevation 69.40 ft higher than the subdivision, hhill. The water in the tank is 55.70 ft deep, hwater, and the tower upon which it sits is 70.40 ft tall (htower), as shown in the figure below. The 12.200 in (inner diameter) pipe that conveys the water to the subdivision can be considered to have an effective length of 2.3600 mi, for the purposes of calculating friction losses. Friction loss can be assumed to vary with pipe velocity, v, by the following equation: ℱ = 0.01 L v2 / D What is the absolute pressure for the water delivered to the subdivision if the flow rate is to be 91,600 gph gallons per hour? (You can assume that the tank is open to the atmosphere and is kept completely full with water pumped into it from a nearby spring.)

You are part of a team that is evaluating the feasibility of building a standardized nursing language into the electronic medical record that will be used by your department. Your group is reviewing the 12 ANA recognized terminologies. The goal is to make recommendations about one or more terminologies that could be built into EMR for use by nurses. Choose one of the 12 ANA recognized terminologies to evaluate (read materials for this unit and visit the website of the sponsoring organization) and answer the following questions:

Which ANA recognized terminology did you evaluate?

What additional information about the terminology did you learn when you visited the sponsoring organization's website?

What would your recommendations be about implementation of the terminology you evaluated into the EMR?

If you did use this standardized terminology in nursing, what would you need to do to prepare staff to think about nursing care and document differently?

These instructions are written with the assumption that code will be done in matlab. You might find the following built in commands useful: length, plot, xlabel, ylabel, title, legend, fzero, plot, disp, axis, axes, min, max.

3. Root finding; Bisection, Secant, Newton. a) Write your own version of the bisection method to solve e 2x − 10x = 0. Assume the root is in the interval [0, 1]. Try to use the matlab command ”fzero” to accomplish the same thing. b) Write your own version of secant method to solve e −2x − 7x = 0. Assume the root is in the interval [1/9, 2/3]. Try to use the matlab command ”fzero” to accomplish the same thing. c) Write your own version of Newton’s method to solve x + sin(x) − cos(2x) = 0.

The owner of a particular house has an unobstructed view of the ocean from his front window. However, the owner of a vacant lot in front of the house announces plans to build a house of his own. Suppose that a one-story house will partially obstruct the view, but a two-story house will block it completely. The builder’s profit and the value of the house are as follows:

a. Is it efficient for the house to be built? If so, how many stories should it be?

Suppose the original owner seeks an injunction halting construction

2. If the court refuses to grant the injunction describe the market outcome if bargaining costs are low. Does the outcome change if bargaining costs are high?

3. Suppose the court grants the injunction, describe the market outcome if bargaining costs are low. Does the outcome change if bargaining costs are high?
