Ex-post (in an accounting sense), Savings ALWAYS equals Investment. However, ex-ante, DESIRED savings may very well be different from DESIRED investment. It is the REAL INTEREST RATE which adjusts to make desired savings equal to desired investment.
Explanation:
- In the basic, closed economy model, Savings=Investment. The reason for this is because, in this model, growing capital stock is not the only item taken into account in Investment. The other item is inventory accumulation.
- Savings is whatever is left over after income is spent on consumption of goods and services, investment is what is spent on goods and services that are not 'consumed', but are durable.
- Equilibrium in the goods market can be expressed in two equivalent ways: (1) desired national saving is equal to desired investment; AS = AD.
- The real interest rate is the rate of interest an investor, saver or lender receives (or expects to receive) after allowing for inflation. It can be described more formally by the Fisher equation, which states that the real interest rate is approximately the nominal interest rate minus the inflation rate.
Answer:
The marketing firm should use the Present Net Value calculation to see if the marketing campaign will add value to the company.
Explanation:
The Present Net Value is a calculation that brings to present time all the future cash flows of an investment. Seeing the campaign marketing strategy as a potential investment, the firm has to identify the revenue entirely caused by the marketing campaign. Doing this, the firm will identify inflows (sales) per year that have to be subtracted to the outflows (marketing expenses). The net value of every year is discounted at a discount rate, and if the Present Net Value is higher than 0, it means that the marketing strategy is expected to bring value to the firm
<span>The independent variable is the size of the aquarium and the dependent variable is the size of the fish population. All other variables in this scenario are held constant. Dependent variables are aspects that the researcher deliberately changes to see what will result from the change. If the food, water temperature and cleanliness are the same and the size of the aquariums is different, that makes aquarium size the independent variable.</span>
