Say’s Law25

Jean Baptiste Say - “Products are paid for with Products”

“It is worthwhile to remark that a product is no sooner created than it, from that instant, affords a market for other products to the full extent of its own value. When the producer has put the finishing hand to his product, he is most anxious to sell it immediately, lest its value should diminish in his hands. Nor is he less anxious to dispose of the money he may get for it; for the value of money is also perishable. But the only way of getting rid of money is in the purchase of some product or other. Thus the mere circumstance of creation of one product immediately opens a vent for other products”

What does it mean – Supply equals Demands In order to obtain a desired commodity, one must first and

necessarily produce a commodity which is itself desirable. Those who produce undesirable commodities, or produce desirable commodities but at unprofitable costs, will fail.

Cash Reserve Ratio – CRR is the portion of deposits (as cash) which banks have to keep/maintain with the RBI. This serves two purposes: Ensures that a portion of bank deposits is totally risk-free Enables that RBI control liquidity in the system, and thereby,

inflation Bank Rate - is the rate at which the central bank

lends to the commercial banksSLR is the portion of their deposits banks are

required to invest in government securitiesRepo rate - is the rate at which the RBI borrows

short term money from the market. After economic reforms RBI started borrowing at market prevailing rates. So it makes more sense to banks to lend money to RBI at competitive rate with no risk at all
