Economics I Money and Money Market (4h)

Money and Money Market The aim of the first lecture is to define money, their forms and functions that the money performs in the economy. Next, we will focus on the origin and evolution of money and the current components of the money supply. In the next step the objective is to define the banking system and to explain the creation of bank deposits (using simple money multiplier). This lecture will form the basis for subsequent interpretation devoted to the money market. The goal of the second lecture is to characterize the money market, define the money supply and money demand and explain the factors that influence them. Moreover, next step is to explain the equation of exchange, the quantitative theory of money and interpret what neutrality of money means.

Content introduction – defining the goals money - definition, origin and evolution of money, functions of money contemporary money and monetary aggregates banking system creation of banking deposits - deposit multiplication money market - money demand and money supply equation of exchange and the quantitative theory of money conclusion – summary, homework

Money - definition, origin and evolution of money, functions of money money: a generally accepted equivalent exchange, means of payment, the most liquid form of assets two basic approaches to money: functional and empirical exogeneity and endogeneity of money origin and evolution of money (depends on the development of exchange) three main functions of money: 1.medium of exchange 2.unit of account 3.store of value

Contemporary money and monetary aggregates definition of current money: money is not currently covered (by gold), with forced circulation, money is accepted because they are legally prescribed currency basic forms of current money: i.coins ii.bills iii.deposit money (accounting, fictitious, bank, giro) monetary aggregates: According the EU methodology: M1: currency in circulation, overnight deposits M2: M1 + deposits with agreed maturity up to 2 years and deposits redeemable at notice up to 3 months M3: M2 + repos, shares/units of money market funds, money market paper and debt securities up to 2 years general classification: aggregate M0, M1, M2, M3 (L).

The sense of breakdown of these monetary aggregates the resolution of monetary aggregates is not identical in all countries a central bank wants to know the size of the money supply - money that businesses really hold and which affect the behavior of market actors and therefore the course of economic events monetary policy can respond quickly and appropriately to adverse economic shocks - events 6

Banking system the existence of the financial market is assumed direct and indirect funding (there is an efficiency of utilization of resources) the banking system in the developed market economies - usually two basic levels: I.a central bank II.the net of commerial banks the main functions of the central bank: a.emission function b.supervision of commercial banks c.monetary policy d.bank of all commercial banks e.state bank f.management of foreign exchange reserves g.representation of the banking system and the state in the field of international monetary relations and organizations the goal of a central bank vs. the goal of commercial banks

Creation of banking deposits - deposit multiplication the deposit multiplication: the process of generating deposits to bank accounts deposit multiplication means the conversion of deposits and reserves in loans and their return on deposits (deposits multiplication condition). The following is the process of converting the mortgage in expenses, which are sales of another economic entity, and these sales will appear again as bank deposits (in banks of “next stage”) Increase in bank deposits is reduced by reserves in next stage (i. e. PMR = reserve requirements) and converges to zero the formula: ΔD = ΔR. 1/r ΔD = incremental deposits ΔR = increment of reserves r = rate of required reserves 1/r...simple money multiplier the process of making the deposit money works in the opposite direction powerful money: reserves + currency outside the banking sector, or the monetary base, these powerful money passes through multiplication 8

Money market - money demand and money supply demand for money: it expresses the amount of money at the price (interest rate) that economic operators are willing to hold requested amount of money may not equal the amount of money offered the theory of liquidity preference - motives of money holding: I.transaction motive II.precautionary motive III.speculative motive 9

10 Keynesian money demand function: transaction and speculative motive L = k.Y r – h.i L = demand for money i L L k = sensitivity to change in real income (Y r ) h = sensitivity to changes in interest rates (i) The demand for money grows when growing real output or price level. L´ when Y r or P i1i1 i2i2 L1L1 L2L2

money supply: the amount of money that the economy has available, = currency in circulation and demand deposits (M1) monetary base, powerful money (MB) reserves + currency outside the banking sector; monetary base (MB) undergoing multiplication and depending on the money multiplier (m) the money supply (S M ) is created: S M = MB.m money multiplier “m” is not constant and predictable the money multiplier is influenced by other effects (behavior of the central bank, commercial banks and depositors) equilibrium at the money market is the result of an intersection of the money supply and money demand S M = D M or M/P = L t11 Money supply, the monetary base, the equilibrium at the money market

12 Equilibrium at money market iNiN M i N = nominal interest rate (the average) M = amount of money S M = money supply (controlled by a central bank) D M = demand for money SMSM DMDM E i1i1 i2i2 i3i3 M1M1 M2M2 M3M3

Equation of exchange and the quantitative theory of money P. Y = M. V P = Price level Y = real GDP M = nominal quantity of money in circulation V = velocity of monetary unit the predecessor of the quantitative theory of money: David Hume ( ) the author of the classical quantitative theory of money (the so-called transaction variant): Irving Fisher (am. Economist, ); began with a simple analysis that every transaction has both a buyer and also the seller the value of all sales in the economy equals the value of all purchases: (AS = AD) 13

the quantitative theory of money: if the velocity of money is given by the practice of the payment and payment technology in a society – it is a stable variable, money supply is given, it is checked by the central bank, and the volume of all transactions (sales) is constant, and the economy is on the level of potential product: then increase the amount of money supply in the economy will cause the rise in price level in the economy reformulation of the quantity theory of money (by conservative economics - Monetarism, an important conclusion of the Monetarism: money can affect real macroeconomic variables in the short term only) 14 The assumptions and conclusions of the quantity theory of money

Homework Exercise “Money and banking deposit creation” Assume Mr. Thrifty had sold treasury bills to the central bank in the amount of 500,- monetary units and after it he deposited this amount in one of the commercial banks. The level of required reserves is 7.5 %. Calculate the money generated by increases in the first 5 stages of deposit multiplication and figure out the overall monetary increase in the banking system - after all stages. Find out the actual level of minimum reserves in your country and calculate simple deposit multiplier. For the Czech Republic, visit the website of the Czech National Bank (

Homework Exercise “Money Market” In the economy output (GDP) was to increase and the households received additional income. Draw a change at the money market and discuss the new equilibrium at the market - determining the equilibrium interest rate and the amount of money supply in the economy. Assume that the economy shows these statistical figures: real GDP = 379,000 mil., average price level (P) = 2.45 and money supply (M) = 362,000 mil. Calculate the velocity of monetary unit.
