Answer: 28.2%

Explanation:

Correlation Coefficient = Covariance / (Standard deviation of Security A * Standard deviation of Security B)

0.52 = 0.022 /( 15% * σ)

(15% * σ) * 0.52 = 0.022

15% * σ = 0.022 / 0.52

σ = 0.0423/15%

= 28.2%

If firms can easily enter and exit a​ market, then A. firms will produce at minimum average cost in the short run. B. firms will
enyata [817]

Answer:

The correct answer is option C.

Explanation:

`If firms can easily enter and exit the market, then firms operating in the market will earn zero economic profit in the long run. This is because the short run is too short for firms to enter and exit so potential firms will enter and exit in the long run.  

If the existing firms will be having negative profits, the firms having loss will exit the market. This will reduce market supply. As a result, the price level will increase. This will go on until all firms will have zero economic profits.  

Similarly, if the existing firms are having positive economic profits in the long run, the other firms will enter the market. This will increase the market supply such that the price level decreases. This will go on till all the firms will be having zero economic profits.

Levart [38]

Answer:

b. Decrease his inputs

Explanation:

The Equity Theory explains the influence that the perception of fair treatment has on the motivation of individuals. Or, from another point of view, in its demotivation.

People tend to compare ourselves to others. With other people's situations, inside and outside work. Thus, we form a perception about what is fair or unfair.

If the result of the comparison is understood as fair, people are more likely to feel motivated. On the contrary, when they perceive that they are treated unfairly, tension and demotivation appear.

In short, when compared to others, people want to be treated fairly for their contributions to the organization. And beliefs regarding what is fair and unfair can affect their motivation, attitudes and, therefore, their behaviors at work.
