Suppose you examine the central bank’s balance sheet and observe that since the previous day, reserves had fallen by $100 millio
aksik [14]

Answer:

The Central Bank is trying to increase money supply.

Explanation:

When the Central Bank makes moves to increase reserves, it means that it is simply trying to mop up excess cash from the economy to fight inflation. Spiking inflation means that the power of a currency is gradually being eroded. The Central Bank cannot allow this to happen so it hits the "Reduce Money In Circulation" button. It does this by reviewing upwards, the money reserves which commercial banks must hold with the Central Bank.  

It can also increase the rate at which it lends to the Commercial Banks and Investment houses. Commercial Banks, in turn, transfer the additional cost of borrowing to businesses who will seek loans. This slows down the rate at which money is pumped into the economy.

In the question, however, we notice that the Central Bank has enervated its reserves. This means that it is pumping more money into the economy. This economic move may have been executed to prevent the economy from slipping into a recession or simply to stimulate the economy.

In the short run, increased money supply means, businesses have more access to funds from commercial banks. More funds mean, more investment. Increased investment spending means the businesses will need to expand operations, hire more staff, and the multiplier effect goes on and on.

Cheers!

If the same number of units of good Y must be given up as each successive unit of good X is produced, then the PPF for these two
andrey2020 [161]

Answer:

PPF : Downward Sloping Straight Line

Explanation:

PPF is the locus of product combinations that an economy can produce, given resources & technology.

It is downward sloping : Because of inverse relationship between two goods- if one has to be increased other has to be decreased , because of same resources & technology.

Marginal Opportunity Cost (Slope of PPC): is ratio of a good sacrifised to gain each additional unit of the other good.

∆ Good sacrifised / ∆ Good gained

If this ratio is same i.e constant amount of a good is sacrifised to gain an additional amount of the other one , the slope of PPC is constant & it is a straight line

Eg : Good1    Good2     MOC [∆Good2/∆Good1]

      0               20             _        

      10             10           -10/10 = -1                  (10-20)/(10-0)

       20              0           -10/10 = -1                   (0-10)(/20-10)

So , same (1) good 2 is sacrifised to attain a good 1 each time.

However Generally: MOC is increasing , because of assumption that resources are unequally efficient in various goods production - shifting good from efficient to inefficient increases sacrifise each time. This makes PPC usually concave.
