The point of diminishing returns can be realised, by use of the second derivative in the above production function. Which can be simplified to: Q= f(L,K). This signifies that output (Q) is dependent on a function of all variable (L) and fixed (K) inputs in the production process. This is the basis to understand.
The functions of money are that it is a medium of exchange, a unit of account, and a store of value. [26] To fulfill these various functions, money must be: [27] Fungible: its individual units must be capable of mutual substitution (i.e., interchangeability). Durable: able to withstand repeated use. Divisible: divisible to small units.
Depending on the state of the economy, fiscal policy may reach for different objectives: its focus can be to restrict economic growth by mediating inflation or, in turn, increase economic growth by decreasing taxes, encouraging spending on different projects that act as stimuli to economic growth and enabling borrowing and spending. The three ...
The law states that as the amount consumed of a commodity increases, other things being equal, the utility derived by the consumer from the additional units, i.e., marginal utility, goes on decreasing. [11] For example, three bites of candy are better than two bites, but the twentieth bite does not add much to the experience beyond the ...
"Money is a matter of functions four: a medium, a measure, a standard and a store." However, many newer texts do not distinguish the function of a standard of deferred payment, subsuming it in other functions. [7] [8] [9] Being a standard of deferred payment is one of the functions of money; it is distinct from:
Monetary economics is the branch of economics that studies the different theories of money: it provides a framework for analyzing money and considers its functions ( as medium of exchange, store of value, and unit of account), and it considers how money can gain acceptance purely because of its convenience as a public good. [1]
[2] Since inflation is itself a derivative—the rate at which the purchasing power of money decreases—then the rate of increase of inflation is the derivative of inflation, opposite in sign to the second time derivative of the purchasing power of money. Stating that a function is decreasing is equivalent to stating that its derivative is ...
Consequently, the importance of the money supply as a guide for the conduct of monetary policy has diminished over time, [65] and after the 1980s central banks have shifted away from policies that focus on money supply targeting. Today, it is widely considered a weak policy, because it is not stably related to the growth of real output.
