3.1Demand for MoneyThe concept of a need for money may strike girlfriend at very first glanceas bizarre. Don"t you just want as much as you deserve to get? Or isn"t moneywhat girlfriend use as soon as you need other goods? here is wherein we have to rememberthat money is a stock not a flow, and also that income and wealthare not money. Need for money is a question of how much of her wealthyou great to hold in the form of money at any allude in time. (Supply ofmoney is also a share concept.)Your demand for money is just how much the your wealth you wishto host as money at any kind of moment in time. The is therefore a share demand. Yourwealth is a stock, and also you should decide exactly how to allocate that stock that wealthbetween different kinds of heritage -- for instance a house, income-earningsecurities, a check account, and cash.Why would certainly you hold any type of of your wide range as money -- together cash or checkingdeposits? Those legacy earn little or no interest. Wouldn"t it be moresensible to organize all your riches in the kind of assets that yield income?Note that:1. Over there is a cost connected with stop money balances (you giveup attention payments),2. Over there is no intrinsic worth in the money balances youhold except in their usage as a tool of exchange. Generally, you acquiremoney in stimulate to eliminate it -- to buy things. When you host it, moneydoes not save you warm, entertain you, or carry out any various other benefit.Economists recognize two factors why civilization will demand money balances,or desire to host a certain stock of money also if over there is no intrinsicvalue for the money balances castle hold.
You are watching: The primary reason people hold money is
3.2Transactions Motive for Holding MoneyThe most noticeable answer is the we hold some money since it"sconvenient to buy stuff with. We"ll call this an initial reason the transactionsmotive. Essentially, it"s practically to organize a details average amountof money at any given time, relying on the kind of purchases girlfriend makeand the dimension of your income.One of the most essential functions that money is that it is theuniversally accepted medium that exchange -- this is the key reason youhold money. Thus, one factor to hold money is to usage it together a method of paymentin transactions in the future. Now, if there was a perfect match betweenthe moments you get money in transactions and also the moments you usage money,you would not need to hold any money in ~ all. If i were paid every Friday,and I might pay every my receipt on the very same day, then ns would need to holdvery tiny money.Unfortunately, in the actual world, there is no going to be anexact match in between when I obtain money and when I must make payments.Let us say that as a occupational study student, you get $500 every month aspayment for your work. This payment comes once a month. However you require topay because that rent, food, movies, books, copying, pens etc. This is spread outover the month. So, top top the an initial of the month, you deposit $500 in youbank account in ~ Fulton bank, and then you retract this money and also run youraccount under to zero end the course of the month. In the food of themonth, friend hove an median money hold of $250. Same thing wake up thenext month, and the next, end the year.Your typical holding that money then, is $250: this is how muchyou have on typical in your bank account end the food of a year.If instead, you were paid $250 every 2 weeks, then you wouldhold $250 in ~ the beginning of the 2 weeks, and also run it down to zero overthe course of 2 weeks, repeat this the next two weeks, and also so on.Can you check out that on average, you would certainly be holding $125 in youraccount?In various other words, the need you have actually for holding money balances willdepend top top the smoothness with which the moment you acquire paid and also the timeyou use the money to make payments mesh. Thus, the require to hold money balancesis in part a an outcome of the institutional payments mechanisms in the economy.An agrarian day laborer in India does no hold an extremely much cash balancesbecause she will acquire paid on a daily basis in tiny amounts and also then useup the money she receives to pay for she transactions of purchase foodalmost immediately. She will have actually a close to zero stop of money balances.But in a system where people are paid with much longer term contracts, regularizedwages and also salaries, and also where they get paid in intervals that a week, a fortnightor a month, and where incomes are relatively stable, the require to host moneybalances will be higher.Even if there was not a perfect match in between my receipts of cashand the moment in which I use it together a means of payments for transactions,if I could costlessly and also immediately convert any bonds I organize intomoney, then there is no reason to host money. I would organize all riches asbonds, and also sell a bond for money the moment I have to make a purchase,holding money for only an instant.So for example, you room paid $500 per month. You host an average balanceof $250 as you start out the month through a $500 financial institution balance, and also then runto under over the month. Yet what if you uncover that you deserve to buy a $250 bondat the start of the month, and also sell that in the middle of the month,earning an attention for half the month? when you gain paid, you can put$250 in your checking account as a money holding, and also buy a bond because that $250.At the finish of 2 weeks, when your $250 has actually been supplied up, you can sellthe bond and also deposit one more $250 in your account. Your mean money holdingshave simply dropped to $125, and also you earn interest on $250 binding every fortnight.You can take this more an further. Why not deposit only $125,and purchase $375 worth of bonds? sell $125 of bond every week, and also earn interestfor 3 weeks. In effect, the question is:Why hold any money balances at all? Why not always hold bondsand only gain hold of money the minute you require it to pay because that transactions?It is costly, in regards to time and also resources, to keep moving inand out of bonds or other assets and money. Because this is the case, i willdesire to host a specific level the money balances top top average, to fulfill myneeds to pay for transactions. This is referred to as the transactions demand formoney.If the attention payments I get on bonds and other heritage ishigh, climate it is worth my when to move in and out the stocks and also bondsand money, so the I have the right to earn this attention payment instead of holdingmoney balances. If the interest rate is not that high, then it is no worthit to relocate in and also out the money and also bonds in order to obtain this interestpayment.Another way to look in ~ it is that the interest price describesthe expense of stop money balances. This is since the interest price tellsyou the amount of interest income you need to forego by stop money balancesinstead that lending out that money and holding one asset favor a bond.This is sufficient to generate a curve which plots the need formoney -- the quantity you great to hold as protest to holding wide range as bonds-- as a role of r. This curve will certainly slope downward.Caution:This looks choose the kind of demand curve you"re offered to in micro. That isn"t.Those represent demand for a flow of a good. This reflects what share of moneypeople wish to hold as part of their asset portfolios.We emphasize the method that r affect transactions need becauseit"s essential to ours money industry story. However two other things will certainly alsoaffect transactions demand. If earnings changes, transactions demand shouldchange v it. As your income rises so execute your expenditures, and hencethe amount of riches you could want to host as money at any type of instant intime. Likewise it"s reasonable to assume that at a national level, demandfor money will flourish as national earnings grows, and decrease if national incomedeclines. Additionally, together the all at once price level that goods and serviceschanges, transactions demand will adjust with it: if you host money tobuy stuff, and it becomes less expensive to buy stuff, you"ll host lessmoney.So the transactions need for money depends on three things:a) interest rate: as we have detailed above, the interestrate is in impact the price of holding money balances. It is the incomeI forego once I host money balances. If the interest price goes up, thenthe returns on relocating in and out that money right into other assets and back willincrease, so world will host a lower level that money balances. If the interestrate falls, then the return on relocating out the money balances and also into assetsare not so great. In this case, it is no worth it to relocate out of moneyinto various other assets and also then earlier when you have to make payment on transactions,so you will organize a higher level of money balances.b) aggregate income: if the volume of income and also outputproduced in the items markets increases, then clearly there will certainly be a largervolume that transactions and also exchanges taking place. Human being will need tohold a larger volume the money to fulfill all these transactions and also make payments.c) price level: if price rise, then world will require tohold a greater level the money balances to accomplish their payments transactions.If prices fall, human being will require a lower volume that money balances to supporta given level the transactions.3.3Speculative Motive for Holding MoneyNow, in enhancement to the transactions motive, over there is one otherreason why world have a demand for stop money balances. This is calledthe speculative motive. Intend that interest prices fluctuate. Ata two percent price of interest, girlfriend would acquire $1,020 in a year"s time inexchange for $1,000 in cash now (i.e. Through buying currently for $1,000 a link thatpays $1,020 in a year, i beg your pardon is the same thing together lending $1,000 in ~ twopercent interest). Mean that the rate of interest is currently two percent,but you intend it to rise to ten percent shortly. At ten percent, $1,000in cash now will obtain you $1,100 in a year"s time. Therefore if girlfriend think interestrates re unusually low and likely to rise, you might keep your riches asmoney rather then to buy bonds in ~ the low current interest rate.Another means to think around this, i beg your pardon will become clearer afteryou finish the next section, is the if friend think that interest rates willrise, then any bonds friend buy now at two percent interest will autumn in valueafter the interest rate rises. "Speculative" simply means speculating --gambling, if you like -- the the value of an asset will change and youcan profit by it. Normally we think of speculating in terms of buying anasset: if I intend that genuine estate in Carlisle is about to increase in value,I can buy some in hope of offering after the price rises. However if i thinkthat one asset"s price is around to fall, i can also speculate through holdingcash, so that I have the right to buy it after the price drops.Of food if i think that interest prices are person that is abnormal high, thenI will certainly buy as numerous bonds as feasible to lock in the greater interest rate.Another method to placed it is that after the interest rate falls, these bondswill be precious more.To recapitulate: in general, as soon as interest rates are high, peoplespeculate that they will not stay high, yet will fall. If this is the case,then civilization will demand less money holdings and move right into bonds. Once (orif) attention rates perform fall, your bonds will climb in value.But, if interest prices are low, world expect that they will certainly goup. So they like to organize on come money balances, and will relocate out the bonds,for are afraid that the value of those bonds will loss when (or if) interestrates increase in the future.3.4Money need as a role of the interest RateSo far, we have actually two factors why the quantity of money the peoplewish come hold can vary through the attention rate. The happens that they bothagree around the nature of the change: at short interest rates money demandwill it is in high, at high interest prices the amount ot your portfolios thatpeople wish to organize as money will certainly be low.Before we placed this together with the it is provided of money, we needto walk over the relation in between the attention rate and the price that bonds.3.5Bond Prices and also the interest RateThe final connect in this story is the the fluctuations in assetsprices are intimately linked to the interest rate. This is because thereason to purchase an asset favor a bond and to agree to loan the end your moneyis the your setup to knife an attention on the loan. Thus, the price that abond is attached to the attention that it assures to offer the lender.There room several ways to think about this. One is to rememberthat a bond is nothing however a promise to do future payments -- a pieceof file that offers you the ideal to get certain payments of money at certainfuture times.The price the a link is simply the amount of money one can sellit for right now. This will influence both the "primary" sector in binding --firms selling bonds come raise money to buy resources goods, or governmentselling bonds to finance a fiscal deficit -- and also the "secondary"market -- human being buying and also selling previously-issued bonds. If i wantto purchase a one-year bond, climate a brand-new one-year link issued by the U.S. Government,and a 2-year link issued a year ago whose holder desire to market it, arethe very same thing as fas as I"m came to -- both are assures to pay moneyin a year"s time.An "interest rate" is just a different means of discussing the price.To gain an interest rate, us subtract the money paid now for the shortcut fromthe money the bond guarantees to pay later, and also call that distinction "interest."If we express the "interest" together a portion of the money paid now forthe bond, we have actually an attention rate. So if the money that the link paysin the future is given, then the greater the price (in money now) that thebond, the lower the difference in between that price and what the link payslater, so the much less the interest and hence interest rate.Here is the very same idea in much more general mathematical language.Let united state say the the interest rate is r%. If you loan $B today,then you will certainly get:A = B (1 + r)Mtwhere A is the amount friend get ago at the finish of t years, B is the amountyou borrow today, and also r is the interest rate you receive.Now, a bond is basically a promise to salary an amount A in ~ the endof t years.Let united state say girlfriend bought a bond that promised to salary you $110 atthe end of one year. If friend bought that bond because that $100, climate in effect,you loaned the end $100 and also got ago $110 at the finish of one year. You got $10in "interest," therefore you space receiving an efficient return that 10%.So, the price girlfriend are prepared to pay because that a shortcut is yes, really equivalentto the major you room lending out this day to obtain repayment in thefuture. Again, the difference between the price you pay now (B) and also theamount the bond guarantees to salary you later on (A) is tantamount tothe interest price that the shortcut is successfully going to provide you. Or A B = ------------ (1 + r)twhere ns is the price you will certainly pay because that this bond today, in order to receivean quantity of a in t year time, based upon an interest price of r. Friend cannow see algebraically what we demonstrated in words -- the train station relationshipbetween the shortcut price and the interest rate.Let united state say friend bought a bond which promised to pay $275 in a yearstime. Girlfriend bought this bond for $250, which method that implicitly, girlfriend wouldhave deserve a 10% interest.Now, let united state say that by the time you go to offer this bond, interestrates increased to 20%. This method that nobody will want to buy her bond for$250, because this bond just promises to give them $275 or a 10% return atthe end of a year. Why will certainly they salary $250 to obtain $275 at the end of a year,when they have the right to lend the end their $250 to who else and also get $300, or a 20%return, in ~ the end of a year?So, you will certainly not uncover anyone who is prepared to buy your bond for$250. If however, you market your shortcut for around $229, then world willbe all set to buy the from you. This is since at $229, if they gain back$275 at the finish of a year, this is virtually equivalent to a 20% return.Thus, if the interest rates go up, the value of her bond willfall native $250 come $229, and you have just made a loss of $21.Can you see that if the interest rates went down the worth ofyour bond would go up, and also you could sell it for more than the $250 youpurchased the for? What is the amount you could sell this shortcut (which promisesto pay $275 at the end of the year) for, if interest rates dropped come 5%?You can shot this v a spreadsheet. For instance you will certainly findthat a shortcut which payment $1,000 in one year"s time would certainly be worth:$990.10 at an interest rate of 1%$980.39 at an interest price of 2%$970.87 in ~ an interest price of 3%$961.54 at an interest rate of 4%$952.38 in ~ an interest rate of 5%$943.40 at an interest rate of 6%$934.58 at an interest rate of 7%$925.93 in ~ an interest price of 8%$917.43 at an interest rate of 9%$909.09 at an interest rate of 10%$900.90 at an interest price of 11%$892.86 at an interest rate of 12%$884.96 in ~ an interest rate of 13%$877.19 in ~ an interest rate of 14%$869.57 at an interest rate of 15%$862.07 in ~ an interest rate of 16%$854.70 in ~ an interest price of 17%$847.46 at an interest price of 18%$840.34 in ~ an interest price of 19%$833.33 in ~ an interest rate of 20%...$666.67 in ~ an interest rate of 50%...$500.00 in ~ an interest price of 100%3.6Money market EquilibriumWhat"s equilibrium? A instance in which there is no furtherpressure for change.Describing equilibrium in the money industry will be a issue ofdescribing what the pressures are that will push the interest rate to change.Equilibrium will occur whenever the interest price stops changing. Thatwill be whenever money supply amounts to money demand.Caution:Do no confuse this through a usual micro market equilibrium story the howthe price that chicken reaches equilibrium. That"s a circulation equilibrium : aflow that chicken produced and a circulation consumed. This is a share equilibrium:there is a specific amount of money turn in the economy, and a certainamount that human being wish come hold.Remember just how we debated equilibrium previously (in section1.3). Equilibrium will certainly be a case in which all the behavioral conditionsare satisfied -- as soon as everyone"s wanted holdings that money same all themoney in reality held. An equilibration process will tell us just how themoney industry actually moves to a case where everybody managesto meet their desired actions (given indigenous the behavior functions). Thesupply of money is the complete stock that money available for use intransactions, and held through the personal sector. The need for money balancesis the total stock the money the the exclusive sector wishes come hold.Note that as soon as we adjust the supply of money, together we go in the last chapter,we are changing the lot in deposit accounts. At any instant in time,all the money has to be somewhere: every disagreement of the money supply mustbe organized by someone.Equilibration Stories:1. Permit us expect that we begin with a it is provided of money the doesequal the demand for money, in ~ an interest price of 5 percent.Now we rise the supply of money. That means people currently holdmore money, family member to bonds, 보다 they supplied to and also want to.In an effort to readjust your portfolios, lock will seek to turnsome that this money right into bonds -- they"ll to buy bonds.This added demand for bonds will certainly drive up the price that bonds.As you know from the ahead section, a higher price of binding is the samething as a lower interest rate.As the interest price falls, money need will rise. Once it risesto equal the brand-new money supply, there will be no further difference betweenthe lot of money human being hold and the lot they wish to hold, and also thestory will end.This is why (and how) an increase in the money it is provided lowers theinterest rate.2. Permit us expect that we begin with a it is provided of money that does equalthe need for money, at an interest rate of 5 percent.Now we decrease the it is provided of money. That way people now holdless money, relative to bonds, than they used to and want to.In an initiative to readjust their portfolios, they will seek to turnsome of your bonds into money -- they"ll sell bonds.These added sales that bonds will drive under the price of bonds.As you know from the vault section, a lower price of binding is the samething together a greater interest rate.As the interest price rises, money need will fall. When it fallsto same the brand-new money supply, there will certainly be no further difference betweenthe amount of money civilization hold and also the lot they great to hold, and thestory will certainly end.This is why (and how) a decrease in the money it is provided raises theinterest rate.We have a notion of exactly how the interest rate affects need to hold moneywhich is shown in the downward-sloping money need curve.To this, us can add the supply of money. Due to the fact that it"s not affectedby the attention rate, it"s a vertical line. The Fed fixes the it is provided ofmoney, as defined in the ahead chapter. This is the full stock ofmoney in circulation -- the money supply at any kind of given time.One MoreCaution: one excess supply of money balances, as developed when weinitially increased the money supply, method that over there are an ext money balancesin the economic climate than individuals desire to organize with them. What room moneybalances? Money balances room the amount of cash and also checking account depositswith the exclusive sector available for use in exchange. In effect, one excesssupply the money balances suggests that in ~ the going attention rate, thereis more cash and a higher level of check account deposits than individualsdesire to hold. This is no the very same thing together an "excess it is provided of apples,"since an excess it is provided of apples method that over there is a team of peopletrying to market apples yet unable to perform so. One excess it is provided of money literallymeans the folks have more cash in your pockets and a bigger level ofchecking accounts than the desire to host with them.3.7Federal make reservation Policy and the interest RateIn effect, the Fed can collection the interest rate by changing thesupply of money. It transforms the it is provided of money through using any type of of its threeinstruments -- open sector operations, discount price changes, or requiredreserve ration transforms -- which work on the banking mechanism to increaseor decrease the share of money the is circulating v the economy.The an altering supply of money, in turn, changes the interest rate throughthe procedure described above.Caution:TheFed can not "set" the sector interest rate by decree. It deserve to not justtell the money industry what the attention rate have to be. Do not confusethe discount rate, which the Fed can set, v the interest ratein general. The discount price is a special price that banks need to payif they borrow reserves. The is entirely feasible that the discount ratewill it is in substantially greater than the market interest rate. It have the right to alsobe lower, though in that instance the Fed would more than likely raise the so the bankswould not be tempted to usage Fed borrowing as a cheap resource of funds.

3.8Other transforms that May influence the interest RateWhen we presented money demand, and also in certain transactionsdemand, the most important component of money demand, we listed that the amountof money that world wished to organize for transactions objectives would beaffected by three things:a. The attention rate, which represented the opportunity expense of holdingmoneyb. The price level, i m sorry would impact how much money to be neededfor transactionsc. Income, since as revenue rises friend buy more, and as that fallsyou to buy lessSo as soon as we attract a money demand curve together a role of r, and also tell out littleequilibration story above, we room assuming that Y and P space not changing-- a ceteris paribus or "other points being equal" assumption.So if one of two people Y or p (the price level) rise, money demand willincrease. Graphically, we represent this together a rightward transition of the moneydemand curve.If either Y or p (the price level) fall, money need will fall.Graphically, we stand for this as a leftward transition of the money demandcurve.©1998 S.
