Answer:
c) a firm does not have sufficient time to change the level of use some of its inputs.
Explanation:
The definition of short-run in economics is not a term to be used for a specific certain period of time but it means that the period of time is too short that the firms cannot change the level they are using of some of their inputs or costs. It means they do have fixed costs they cannot change. For example, all machinery installed, a yearly rent paid, electricity or others that the firm cannot change unless there is sufficient time. In a short period of time, it will have those costs anyway. The firm cannot change the level of that input. And it is short run of at least one input. It may be many. But it is not necessary to have all inputs unchanged to consider that period of time as short-run.
However, firms can change level of inputs if they have more time. That is cost the long run. All costs are variable costs when we are in long run.
The expected return on this portfolio will be given by:
E[P]=Rf+(E[Rm]-Rf)β
Where:
Rf=Risk Free interest rate
Rm=Return on the market portfolio
β= Market Beta
The return on our portfolio will be:
E[p]=0.043+(0.128-0.043)0.013
=0.043+0.085*0.013
=0.044105
=4.4105%
The unemployed people in this economy are MASON AND ABBOT.
Unemployment is said to occur in an economy, when people who are in the working age bracket actively search for work for a long time without getting any. There are different types of unemployment. Unemployment rate is usually used to gauge how healthy an economy is. In the scenario given above, it can be seen that both Mason and Abbot are of working age and they are both actively searching for work without finding one. <span />

Explanation:
The correct phrase should be:
Generally speaking, oligopolistic industries producing raw materials and semifinished goods usually offer standardized products, while oligopolists producing consumer goods usually offer differentiated products.
An example of an oligopolistic industry that we all know about is the car industry. There are very few car companies in the world since only very large companies can actually manufacture cars. Car companies offer differentiated products.
