2 5. SAVINGS, INVESTMENT AND THE CREDIT MARKET EQUILIBRIUM OR FROM THE RENTAL PRICE OF CAPITAL TO THE REAL INTEREST RATE 1. Invesmen and savings mee in he credi (also loan) marke Households may have a PREFERENCE o save for consumpion omorrow. This is capured by he following exremely simple SAVINGS FUNCTION: (E19) S () = sy () Households simply save a consan fracion s of heir oal income Y (his includes labor and capial income). Savings are deposied in banks ha use hem o make loans o firms. Firms use credi o buy NEW machines. INVESTMENT refers o he oal purchases of NEW MACHINES and ALSO TO THE VOLUME OF LOANS IN THE ECONOMY. Firms can herefore buy machines or insead ren hem. This will give rise o he ren-or-buy decision which deermines he real ineres rae. UPF Macroeconomics I, Slide SET 2 Slide 2

RENTAL MARKET FOR CAPITAL GOODS UPF Macroeconomics I, Slide SET 2 Slide 3
4 How firms finance purchase of new machinery (1) Loans: firms ask banks for loans and banks make hese loans wih he savings of households (2) Reained earnings: firms ask heir owners wheher hey can reain some of heir earnings in order o fund purchases of new machinery (3) Issues of new shares: hey purchases new machines and issue propery iles o he machines (shares) direcly o households In he Solow environmen hese ways of financing machinery are all EQUIVALENT. We can herefore jus hink of firms financing he purchase of new machinery by asking banks for loans. UPF Macroeconomics I, Slide SET 2 Slide 4
5 2. The ren or buy decision 1. The user cos of capial definiion in discree ime Firm can demand credi/loans o purchase capial goods: - in principle, his gives hem an alernaive o he renal marke for capial - insead of rening he capial good nex year, for example, you could buy i on credi oday, use i for one year and hen sell i off. The cos of doing so is he USER COST OF CAPITAL User Cos One-year-Period = 1 + r( + 1) * p ( ) 1 p ( + 1) [ ] [ δ ] K K -higher real ineres rae and depreciaion rae increase user cos -high fuure price for capial goods relaive o curren price reduces user cos UPF Macroeconomics I, Slide SET 2 Slide 5
6 2. The user cos in one-secor growh models (which includes, among many, he Solow model) Assume ha consumpion goods and invesmen goods can be produced wih idenical echnologies. In his case, he price of he invesmen goods relaive o he capial good is always uniy. If invesmen goods were more expensive only invesmen goods would be produced by profi maximizing firms. And vice versa. (E21) User Cos One-year-Period [ 1 r ( 1) ] [ 1 δ ] = + + = r ( + 1) + δ UPF Macroeconomics I, Slide SET 2 Slide 6
7 3. The credi/loan marke equilibrium The CREDIT/LOAN MARKET is in equilibrium a ime when: SAVINGS()=INVESTMENT() S()=I() As we will see, he CREDIT/LOAN marke is brough ino equilibrium by adjusmens of he REAL INTEREST RATE. The ren or buy decision and he credi/loan marke equilibrium: -firms can eiher buy capial goods oday (inves) for fuure use, or go o he renal marke for capial in he nex period. R+ ( 1) -he cos of rening nex period is he cos of buying he invesmen goods use i and resell wha is lef is r ( + 1) + δ UPF Macroeconomics I, Slide SET 2 Slide 7
8 We will now show ha in a CREDIT MARKET EQUILIBRIUM where INVESTMENT=SAVINGS>0: (E22) R ( + 1) = r ( + 1) + δ PART 1 OF THE ARGUMENT: R ( + 1) < r ( + 1) + δ Can i be ha and ha, a he same ime he credi marke is in equilibrium? No: in his case no firm wans o inves and I<S. Given he expeced renal cos of capial, firms find i cheaper o ren some of his exising capial raher han inves in new one. Hence, he savings of HH are greaer han he invesmen (which is 0). This siuaion will be eliminaed by a fall in he real ineres rae. UPF Macroeconomics I, Slide SET 2 Slide 8
9 PART 2 OF THE ARGUMENT: R ( + 1) > r ( + 1) + δ Can i be ha credi marke is in equilibrium? and ha, a he same ime he No: in his case firms wan infinie invesmen because hey can earn a profi by buying capial oday and ren i ou omorrow. Hence, he desired invesmen by firms will be greaer han he desired savings by firms, I>S. Hence, for he credi marke o be in equilibrium firms mus be indifferen by buying oday and expecing o ren nex period R ( + 1) = r ( + 1) + δ UPF Macroeconomics I, Slide SET 2 Slide 9
10 Because he expeced renal price of capial nex period is equal o he expeced equilibrium MPK, see he saic equilibrium condiion, we obain: (E23) MPK( + 1) = r( + 1) + δ -in equilibrium firms inves o he poin where he MPK is equal o he real ineres rae plus depreciaion MPK( + 1) δ = r( + 1) - he equilibrium real ineres rae is equal o he ne MPK of he capial a sociey has accumulae up o ime UPF Macroeconomics I, Slide SET 2 Slide 10

12 4. The credi marke equilibrium and he link beween presen and fuure (or he capial accumulaion equaion in equilibrium) As far as he economics of he Solow model are concerned we are done! -We know how o deermine oupu a a given momen in ime given L and K; we also how o obain facor prices and he real ineres rae. - Now we know how o deermine omorrow s capial sock given oday s capial sock and employmen: Depreciaion (E26) K() K& () = I() δk() = S() δk() Ne Invesmen Gross Invesmen UPF Macroeconomics I, Slide SET 2 Slide 12

14 6. THE DYNAMICS OF THE SOLOW MODEL 1. The dynamics of capial accumulaion To solve he Solow model compleely, we need o specify he evoluion over ime of some EXOGENOUS facors like EFFICIENCY A and LABOR SUPPLY L We will assume ha labor supply grows a (exogenous) rae n: (E29) L () = L(0) e n (E30) L &() = nl () (E31) L &() L () = n UPF Macroeconomics I, Slide SET 2 Slide 14
15 Similarly, we will assume ha exogenous efficiency A we will assume growh a (exogenous) rae a: (E32) A() = A(0) e a (E33) A& () = aa() (E34) A &() A () = a UPF Macroeconomics I, Slide SET 2 Slide 15
16 SUMMARIZING THE DYNAMIC EQUATIONS OF THE SOLOW MODEL (E35) K& = sf( K, AL ) δ K A& = aa (E36) L& = nl (E37) Following all 3 (so-called sae) variables separaely over ime is somewha cumbersome and inconvenien. And WE DO NOT HAVE TO, because as we have seen many hings depend on capial per efficiency worker, NOT separaely on K, L, and A. UPF Macroeconomics I, Slide SET 2 Slide 16
17 More convenien o focus on he change over ime of CAPITAL PER EFFICIENCY WORKER WHY? k% = K A L - deermines oupu per efficiency worker hrough he producion funcion in efficiency form Y y% ( ) = = f k% AL - geing o he quaniies we are ineresed in is simple (E38) y = y% A (E39) r + δ = f '( k% ) w (E40) f( k) k f '( k) A = % % % UPF Macroeconomics I, Slide SET 2 Slide 17
18 From TIME CHANGES OF K,L,A o TIME CHANGES in capial per efficiency worker k% K = AL K K K k% = L A AL AL A L 2 2 k% K K L K A = A L AL L AL A (E41) K k% k% n k% a = AL UPF Macroeconomics I, Slide SET 2 Slide 18
19 Using he equilibrium capial accumulaion equaion (E28): (E42) K sf( K, AL ) K k% δ = k% n k% a= k% n k % a AL AL (E43) sf( K, AL ) k% = k% δ kn % ka % AL (E44) k% = sf ( k% ) ( ) { δ + n+ a k% ACTUAL SAVINGS AND INVESTMENT BREAK-EVEN INVESTMENT UPF Macroeconomics I, Slide SET 2 Slide 19
20 This equaion gives us he change in k% as a funcion of he presen k% Therefore, given a saring poin k% (0), i allows o sudy he whole ime pah of k%. SO NOW WE ARE DONE WITH THE MECHANICAL DYNAMIC ASPECTS OF THE SOLOW MODEL TOO. Now is he ime o remember: Wha is i we wan o know abou? UPF Macroeconomics I, Slide SET 2 Slide 20
21 Wha we wan o know: INTERMEDIATE QUESTIONS - Will capial per efficiency worker INCREASE or FALL over ime? - Will capial per efficiency worker GROW FOREVER? - Will he GROWTH RATE of capial per efficiency worker INCREASE or DECREASE in ime? FINAL QUESTIONS - Wha does his imply for INCOME, WAGES, and INTEREST RATES. The quesions are mos easily approached graphically. UPF Macroeconomics I, Slide SET 2 Slide 21

44 2. From capial accumulaion o growh of oupu per worker The easies way o make he link is o assume he producion funcion akes he so-called Cobb-Douglas form α (E47) Y = ( K ) ( AL ) 1 where 0< α < 1 is he elasiciy of oupu wih respec o capial: α (E48) Y K K Y or = α Percenage increase in = α *Percenage increase in K Y UPF Macroeconomics I, Slide SET 2 Slide 44
45 The Cobb-Douglas producion funcion in efficiency uni form is (E49) Y A L K = AL α or (E50) y% = % k α 0< α < 1 hence is also he elasiciy of oupu per efficiency worker wih respec o capial per efficiency worker. UPF Macroeconomics I, Slide SET 2 Slide 45
46 Growh in oupu per worker - oupu per worker is oupu per efficiency worker imes efficiency y = A y% = Ak% α (E51) (E51) - differeniaing herefore yields ELASTICITY OF OUTPUT TO CAPITAL y } A y% k% = + = a{ + α y A y% EFFICIENCY k% { GROWTH CAPITAL PER EFFICIENCY GROWTH UPF Macroeconomics I, Slide SET 2 Slide 46

Real wage growh and changes in he real ineres rae Again, he easies case is o assume he producion funcion akes he so-called Cobb-Douglas form α ( ) ( ) 1 α K - he real wage is AL w = MPL = L α (E53) w α A ( K ) ( AL ) = (1 ) = (1 α) Y (E54) w = (1 α) = (1 α) y L w = (1 α) y α α ( K ) ( AL ) 1 w& = w y y& L α he real wage is simply A CONSTANT FRACTION of income per capia and real wage growh is EQUAL TO oupu per worker growh UPF Macroeconomics I, Slide SET 2 Slide 49

53 7. THE EFFECTS OF AN INCREASE IN SAVINGS ON INCOME 1. Growh in he long run (in he balanced growh pah) Afer having analyzed he DYNAMICS of growh for all momens in ime we will now focus on he long-run, i.e. he balanced growh pah - we already have shown ha (E57) k% y% = = 0 k% y% BGP BGP and herefore (E58) k k BGP y = = a = GROWTH LABOR-EFFICIENCY y BGP UPF Macroeconomics I, Slide SET 2 Slide 53
54 Resul: The long-run growh rae oupu per worker of a counry is deermined by he GROWTH RATE OF LABOR EFFICIENCY ONLY. -In paricular, he long-run growh rae of oupu per worker does NOT depend on he SAVINGS RATE a all. -This is because of DECREASING RETURNS TO CAPITAL IN PRODUCTION. Recall ha k% = sf ( k% ) ( δ + n+ a) k% (E59) { ACTUAL SAVINGS BREAK-EVEN AND INVESTMENT INVESTMENT f ''( k % ) < 0 Because of decreasing reurns o capial, SAVINGS per efficiency worker rises less han proporionally wih capial. Bu BREAK-EVEN INVESTMENT rises proporionally. So hey will be evenually equal NO MATTER wha he SAVINGS RATE may be. A ha poin growh in income per capia is equal o growh in labor-efficiency. UPF Macroeconomics I, Slide SET 2 Slide 54
55 2. Oupu per worker in he long run (in he balanced growh pah) The savings rae does, however, affec he LEVEL OF OUTPUT PER WORKER - having a simple expression for oupu per worker in he BGP is easies wih a Cobb-Douglas producion funcion - noe ha in he BGP: (E60) 0 = sf ( k% ) ( ) { δ + n+ a k% ACTUAL SAVINGS AND INVESTMENT BREAK-EVEN INVESTMENT (E61) k% k s y = % % f( k% ) = δ + n + a BGP BGP UPF Macroeconomics I, Slide SET 2 Slide 55
56 - he Cobb-Douglas producion funcion in inensive forms is y% k α which yields: (E62) k% k% α BGP s = δ + n + a solving for he BGP amoun of capial per efficiency worker: (E63) k% BGP s = δ + n+ a 1 1 α = % he amoun of capial per worker can be obained by muliplying by efficiency A (E64) k BGP, s = δ + n+ a 1 1 α A UPF Macroeconomics I, Slide SET 2 Slide 56
57 - subsiuing in he producion funcion yields oupu per efficiency worker and oupu per worker (E65) y% BGP s = δ + n+ a α 1 α (E66) y BGP, s = δ + n+ a α 1 α A kbgp, s = y δ + n + a BGP, UPF Macroeconomics I, Slide SET 2 Slide 57
58 Hence, if efficiency growh is consan in ime, as assumed, we ge ha income per capia growh in he BGP is consan in ime. We also ge ha he CAPITAL-OUTPUT (k/y) raio is consan in ime. A consan capial-oupu raio and seady growh of income per capia is ofen seen o describe he U.S. well, especially for a longer ime period. (Solow developed his model hinking of he U.S. economy.)

63 8. QUANTITATIVE IMPLICATIONS OF THE SOLOW MODEL 1. Effec of savings on long run income We have seen ha he effec of he savings rae on long run oupu per worker can be obained very easily when he producion funcion is Cobb-Douglas (E67) y BGP, s = δ + n+ a α 1 α A -- he PERCENTAGE INCREASE in long-run income ha comes from a ONE- PERCENT INCREASE in he savings rae is he (E68) α = 1 α y BGP, s y s BGP, UPF Macroeconomics I, Slide SET 2 Slide 63
64 - he greaer he elasiciy of oupu wih respec o capial, α he greaer he effec of savings on long run income -- HOW LARGE IS THIS ELASTICITY? I urns ou ha under he assumpion of he Solow model here is a simple way o esimae α Y K - he definiion of α is: α = = MPK K Y Y - equilibrium in he capial marke implies ha - hence r K + δ = MPK ( r + δ ) K α = = share of CAPITAL in income Y - consan reurns o scale implies ha all income is paid o capial or labor; herefore (E69) α = 1 share of LABOR in income UPF Macroeconomics I, Slide SET 2 Slide 64
65 - he LABOR INCOME SHARE in indusrialized counries is around 1/3: (E70) α 1 2/3 1/3 1 = = = 1 α 1 (1 2/3) 2/ hence, increasing he savings rae by 1% raises long-run income per capia by only 0.5% under he assumpions of he Solow model -- HOW MUCH CAN DIFFERENCES IN SAVINGS RATE OF CAPITAL EXPLAIN? (E71) y BGP, s = δ + n+ a α 1 α A UPF Macroeconomics I, Slide SET 2 Slide 65
66 - ake wo counries ha are idenical in everyhing bu SAVINGS/INVESTMENT raes -denoe heir savings raes by s1 and s2 respecively; wha is hen he difference in long-run incomes beween he wo counries? (E72) (E73) y y y y COUNTRY1, BGP COUNTRY 2, BGP COUNTRY1, BGP COUNTRY 2, BGP s1 = s2 α 1 α 1/ = = 9= raher small given he enormous differences in savings raes differences in savings raes alone canno explain enormous differences in income beween rich and poor counries UPF Macroeconomics I, Slide SET 2 Slide 66
67 2. Income per capia versus oupu per worker The Solow model is abou OUTPUT PER WORKER; how do we ge from here o OUTPUT PER CAPITA? As L=NUMBER OF WORKER, we ge (E74) Y WORKER Y = POPULATION POPULATION L his can be wrien furher as ((E75)) Y = POP WORKINGAGE POP LABORFORCE EMPLOYMENT Y POP WORKINGAGE POP LABORFORCE L UPF Macroeconomics I, Slide SET 2 Slide 67
68 hence (E76) INCOME or OUTPUT per CAPITA = DEMOGRAPHIC FACTOR X LABOR FORCE PARTICIPATION RATE X (1-UNEMPLOYMENT RATE) X OUTPUT PER WORKER Income or oupu per capia may herefore be low because of - LOW oupu per worker - HIGH unemploymen among hose who do paricipae - LOW paricipaion of he populaion in he labor marke - HIGH share of children and reired persons UPF Macroeconomics I, Slide SET 2 Slide 68
69 Wih informaion on OUTPUT PER HOUR WORKED, we can do even beer and decompose oupu per worker ino: (E80) Y HOURS Y = L WORKERS HOURS where Hours= oal hours worked in he economy Hours/Workers= hours worked per employed person UPF Macroeconomics I, Slide SET 2 Slide 69

Rober Gordon from Norhwesern Universiy and co-auhors have researched his in much deail; hey argue ha he process sopped because of boh TFP and capial growh and ha new INFORMATION and COMMUNICATION TECHNOLOGIES (ICT) played a role UPF Macroeconomics I, Slide SET 2 Slide 87

96 3. Convergence 1. Definiion and mechanisms Convergence: - When poorer counries grow faser han rich counries. Mechanisms: - Higher average and marginal produciviy of capial in poor counries (he flip side of decreasing reurns o capial) - Technological convergence UPF Macroeconomics I, Slide SET 2 Slide 96
97 2. Was here convergence among oday s rich counries? Many of oday s rich counries have daa on oupu per person going back o he 19h cenury. This allows us o ask: Did hose ha sared poorer grow faser since he 19h cenury? For he period , his is he quesion asked by Baumol Produciviy, Convergence, and Welfare American Economic Review, 1986 UPF Macroeconomics I, Slide SET 2 Slide 97
98 Baumol Slide1: Convergence among ex-pos rich UPF Macroeconomics I, Slide SET 2 Slide 98
99 The figure suggess a clear paern of convergence among oday s rich counries. BUT here are problems wih his approach: Problem 1: The sample we have are only counries ha evenually became rich. Maybe here were some counries ha were as rich as, say, Finland, in he 19h cenury, bu hen did poorly. These counries would hen BREAK he paern of convergence of he figure. Wha counries would ha be? -Chile -Argenina -Porugal - DeLong considers a sample consising of he riches counries in he 19h cenury (no oday) and follows hem over he same ime period. DeLong Have Produciviy Levels Convergence? American Economic Review, UPF Macroeconomics I, Slide SET 2 Slide 99

101 Problem 2: Relaed o daa qualiy. If he daa for he 19h cenury is worse han ha of oday, we may conclude based on his daa ha here is convergence when in realiy here is none. Imagine: - In 1870: all counries really have income he same income, equal o y(1870) - In 1980: all counries have STILL he same income Now imagine ha he daa we have is wrong and underesimaes 1870 income for some counries and overesimaes i for ohers. I.e. here is measuremen error. Then we ge he following figure. UPF Macroeconomics I, Slide SET 2 Slide 101

103 DeLong argues ha if his measuremen problem is aken ino accoun han he paern of growh acually indicaes DIVERGENCE among rich counries in he 19h cenury. Probably no oo surprising because: - he forces of convergence are mos likely sronger in marke economies, i.e. economies wih economic freedom and proeced propery righs - many economies did no conform o his paern over long periods of ime because of communisms, expropriaory dicaorships ec. UPF Macroeconomics I, Slide SET 2 Slide 103
104 3. Convergence among regions We can also look a he paern of convergence across regions of one counry. The following wo figures are abou long-erm income convergence and oupu convergence across he STATES of he UNITED STATES.

105 UPF Macroeconomics I, Slide SET 2 Slide 105
106 UPF Macroeconomics I, Slide SET 2 Slide 106
107 Advanages and disadvanages of looking for convergence across regions Advanages: Regions in he same counry end o share he same poliical framework. Differences in income are herefore more likely o be driven by economics. Disadvanages: Income of a region is closely relaed o wha he region specializes in (agriculure?, gold mining?, car manufacuring?, financial services?) and o he process of migraion of ciy-formaion (urbanizaion). Growh heory has lile o say abou all ha. UPF Macroeconomics I, Slide SET 2 Slide 107
108 4. Convergence world-wide afer World War II Wha if we look a he relaion beween oupu growh and iniial oupu per worker for as broad a sample as possible in he pos WWII period? As has been documened by many economiss, we ge no indicaion of convergence. Rich counries may on average even have been growing faser han poor counries. UPF Macroeconomics I, Slide SET 2 Slide 108

110 Or for he period: UPF Macroeconomics I, Slide SET 2 Slide 110
111 I looks like poor counries have been falling behind in oupu per worker Bu does his prove he absence of he wo convergence mechanisms: - decreasing reurns o capial? - echnological convergence? No necessarily, because BAD ECONOMIC POLICIES in many poor counries have hindered growh. For example: no proecing even mos basic human and economic righs no invesing in criical facors like infrasrucure (roads, elecriciy ec.) and human capial (primary and secondary educaion) UPF Macroeconomics I, Slide SET 2 Slide 111

117 How could we check in pracice? By running a regression. For example, esimae he parameers a, b, c below ln y ln y = counry,1960 counry, a * SchoolingInvesmen + b* PoliicalSabiliy counry counry + c*ln y counry,1960 GROWTH EXPLAINED BY POLICIES GROWTH EXPLAINED BY CONDITIONAL CONVERGENCE This is done in Barro Economic Growh in a Cross-Secion of Counries, Quarerly Journal of Economics UPF Macroeconomics I, Slide SET 2 Slide 117
118 Growh assuming same schooling and poliical sabiliy in all counries Income in 1960 UPF Macroeconomics I, Slide SET 2 Slide 118
119 Approach makes sense bu also has problems. Because ECONOMIC POLICIES are no exogenous and maybe a leas in par due o low iniial incomes. For example: - The approach says ha low growh in poor counries may be due o low invesmen in schooling. Bu maybe low invesmen in schooling is a consequence (no cause) of he povery of counries. - The approach says ha low growh in poor counries may be due o poliical insabiliy. Bu maybe poliical insabiliy is a consequence (no cause) of he povery of counries. -Ec. UPF Macroeconomics I, Slide SET 2 Slide 119

127 Avoid ha by building in a process of convergence (or growh slowdown): ln a + b y counry, 1 counry, * X 0.02*ln counry, + ln y = y counry, This can be done by building he forecass of growh in hese counries around he Solow model. UPF Macroeconomics I, Slide SET 2 Slide 127
