Answer:

Following are the solution to the given question:

Explanation:

The decrease of a marginal input return implies that its input is increasing by one unit, thereby decreasing its marginal input product.

Function of production

F(K, L) = AK^{\frac{3}{4}} L^{\frac{3}{4}}

Its capital products subject (MPK) is derived by differentiating the factor of production from K.

MPK = \frac{3}{4}\times AK^{\frac{3}{4}} - 1L^{\frac{3}{4}}\\\\MPK = \frac{3}{4}AK^{-\frac{1}{4}}L^{\frac{3}{4}}\\\\MPK = \frac{3}{4}\times A\times (\frac{L^{\frac{3}{4}}}{K^{\frac{1}{4}}})

Note: When a value is changed from numerator to denominator, then the power symbol shifts between positive to negative.

Since k is in the denominator, K decreases \frac{3}{4}\times A\times (\frac{L^{\frac{3}{4}}}{K^{\frac{1}{4}}}), and therefore MPK is reduced.

There's hence a decreased effective return on capital again for production function.

Its marginal labor product (MPL) is determined by distinguishing the manufacturing function from L.

MPL = (\frac{3}{4})\times AK^{\frac{3}{4}}L^{\frac{3}{4}}-1\\\\MPL = (\frac{3}{4})AK^{\frac{3}{4}}L^{-\frac{1}{4}}\\\\MPL = (\frac{3}{4})\times A\times (\frac{K^{\frac{3}{4}}}{L^{\frac{3}{4}}})

The denominator of L reduces L (\frac{3}{4})\times A\times (\frac{K^{\frac{3}{4}}}{L^{\frac{3}{4}}}) and therefore reduces MPL.

So there is a decreasing marginal return to labor in the production function.

deff fn [24]

Answer:

As the question was not complete. I have attached the complete question in the attachment. Please refer to attachment.

Explanation:

<em>By using, LD = 95- 3w and w1 = 7.25 and w2 = 9. We get, </em>

<em>LD1 = 95-3(7.25) = 73.25 </em>

<em>LD2 = 95-3(9) = 68 </em>

Elasticity = Change in labor demand/ change in wage rate = ((68- 73.25)/ 73.25)/ ((9-7.25/7.25)) = -0.33

The 11 percent change in the wage rate causes, 33% change in labor demanded, as shown by the elasticity, the labor demand decreases with increase in wage rate.

Zarrin [17]

Answer:

structural unemployment

Explanation:

Unemployment is a situation where people who are ready and willing to work can not find one.

<u><em>Structural Unemployment</em></u>

<em>Structural Unemployment: </em><em> One of the reasons for unemployment is when the production process is automated. In this instance, works and tasks that were formerly done by humans and now been taken over by machines</em>

<em>For example, the work formerly done by Carl has now been taken over by robotics. Usually , this will lead to mismatch of skills because the skills possessed by Carls are no longer needed by his employer.</em>

Therefore, Carl is experiencing structural unemployment

Determine whether the study depicts an observational study or a designed experiment. A researcher obtained a random sample of 10
Anastasy [175]

Answer:

A. Observational study

Explanation:

An observational study measures the characteristics of a population by studying individuals in a sample, but does not attempt to manipulate or influence the variables of interest.

A designed experiment applies a treatment to individuals (referred to as experimental units or subjects) and attempts to isolate the effects of the treatment on a response variable.

Hence, we can see that proposed study is observational.
