Angelo Gabrielle F. SantosOUTLINEMacroeconomic AccountingWhat are the different measures of economic performance?What are the components of the Balance of Payment (BOP) account?When does the BOP surplus/deficit arise?Angelo Gabrielle F. SantosMacroeconomic AccountingOR:Wherein:Y = Gross Domestic ProductNX = Net exports
Note: CA = NX + net unilateral transfers
Angelo Gabrielle F. SantosDifference between GDP and GNPGNP is a measure of economic activity by every citizen of a country, regardless of location; while GDP is a measure by location.E.g. GNP- output produced by every Filipino around the world; GDP- output produced in the Philippines including those of foreigners. Angelo Gabrielle F. SantosDifferent measures of economic activityNet National Product (NNP):= GNP depreciation2. National Income:= NNP indirect business taxes3. Personal Income (PI):= NI income earned but not received + income received but not earned4. Private Disposable Income (Y-T) or (Yd)= PI personal taxes
Angelo Gabrielle F. SantosMacroeconomic AccountingBalance of Payment (BOP) Accounts
Where:CA = Current AccountKA = Capital AccountFA= Financial Account
Angelo Gabrielle F. SantosCurrent Account (CA)Includes (X-M) goods and services, and unilateral transfers.Exports and inward remittances are positive entries in the BOP sheet.Example: OFW sends money to relatives in the Philippines. This is recorded as a positive entry in the balance sheet.
Angelo Gabrielle F. SantosCurrent Account DerivationWherein:T= taxesSp= household savingsSg= government savingsSn= national savings
Angelo Gabrielle F. SantosFinancial Account (FA)E.g., portfolio investments, foreign direct investments, paper assets, etcInflows of these instruments are recorded as positive entries in the balance sheet.Example: A Japanese corporation buys treasury bonds in the Philippines. This is a positive entry for the Philippines balance sheet, while it is a negative entry for Japans balance sheet.
Angelo Gabrielle F. SantosBOP Surplus or Deficit
Wherein FA(official) is the official reservesettlement balance. Angelo Gabrielle F. SantosBOP Surplus or DeficitFA (official) is negative (positive) in order to offset the change in CA and/or FA (private). I.e., if CA + FA (private) > 0, then FA (official) is negative (positive), and there is a BOP surplus (deficit).For deficit (surplus) to clear out, the Central Bank has to sell (buy) currency at the Foreign Exchange market. International reserves would fall (rise).Angelo Gabrielle F. SantosOUTLINEMoney SupplyWhat are the functions of money?How did money evolve?What are the classification of monetary aggregates?What are the components of the central banks and the banking systems balance sheets.What are the quantitative tools of monetary policy?
Angelo Gabrielle F. SantosFunctions of MoneyMedium of ExchangeSuppose: a barter economy with n commodities. Then, there are set of prices due to the problem of double coincidence of wants. 2. Unit of Account- prices in terms of money rather than other goods.3. Store of Value- money used to purchase future goods by foregoing current purchases.
Angelo Gabrielle F. SantosEvolution of MoneyCommodity moneyE.g., gold, cigarettes in POW camps (see Radford,1945)*Fiat money- Faith that a paper bill, with almost no intrinsic value is recognized by law.E.g. paper bills, coinsE-moneyE.g., Globe G-cash, Paypal, credit card payments

Angelo Gabrielle F. SantosMonetary AggregatesM1 includes currency in circulation, demand deposits and travellers checksM2 includes M1 and quasi-money (e.g., savings deposit, small-term time deposits)M3 includes M2, long-term time deposits, and repurchase agreements.Note! The Central Bank looks at M3

For the BSP: there is a net increase in MB
For the bank: no net effect

Using (5)Let
Where MB= asset side of the CBs balance sheet Angelo Gabrielle F. SantosChannels of Monetary Transmission (Mishkin, 1996)Interest Rate Channel
Inverse relationship between price of bonds and the interest rate ( )Excess supply of money (ESM) => Excess demand for bonds (EDB)
Exchange Rate ChannelEquity Price Channel (Via Tobins Q) Others: see (Mishkin, 1996)
Angelo Gabrielle F. SantosInverse relationship between price of bonds and interest rateIs equal to the present value of cash flows arising from the asset.Present value formula:
Where: PV= present valueCF= cash flowFV= future valuei= interest rate
Angelo Gabrielle F. SantosDifferent Types of LoansSimple Loan
Fixed Payment (FP) LoanPrice of asset= present value of cash flows
Angelo Gabrielle F. SantosDifferent Types of LoansCoupon Bond: let C= coupon payment
Discount Bond
Angelo Gabrielle F. SantosDifferent Types of LoansConsol or PerpetuityIs a coupon bond with no maturity (FV=0).Coupons are paid forever.
Geometric Series:
Angelo Gabrielle F. SantosDerivation of the Price of ConsolUsing formula of infinite geometric series on the denominator
Angelo Gabrielle F. SantosESM and EDBAn increase in the money supply leads to excess supply of money (ESM). An ESM leads to an excess demand for bonds (EDB).Suppose there are only two assets: money and bondsThere is asset market equilibrium (i.e., asset supply = asset demand)Angelo Gabrielle F. SantosESM and EDBIn real terms: Asset market equilibrium
Where L is real money demand
