ECON 203 Review Session Payment to Canada = Export -\> **Receipt** (sale of a product or receipt for Canada)-\> credit (+) Payment from Canada = Import -\> **Payment** (purchase of a product or asset from foreigner) -\> debit (-) **Current Account** (CA)= [Trade account] (payment and receipt of imports and exporting goods) + [Capital-service account] (net investment income earned from foreign holdings such as dividend, coupons, interest payments) **Capital Account** (KA)= Records transactions in assets including bonds, share of a company, real estate and factory **Purchasing a foreign asset** = purchase of foreign good Government increases in foreign reserves are debit and decreases of foreign reserves are credits **Outflow = Purchasing a foreign asset** = requires a **payment** from Canadians to foreigners, it's a "debit" (-); cases financial capital to leave Canada **Inflow = Selling a Canadian asset** = **receipt** for Canada, it's a "credit" (+); causes financial capital to enter Canada **Balance of payments** CA + KA = 0 **Current Account Balance** = X -- Imports + net foreign investment income If interest Canada goes down = bonds less attractive since the interest on it is low =\> KA goes down =\> \$CAD depreciates **Foreign exchange market** = Appreciation (fall in exchange rate) and Depreciation (rise in exchange rate) If \$CAD goes from 1\$CAD/ 1\$USD to 1.3 CAD/ 1\$USD =\> depreciation **Canada-Euro** = Demand for euros = supply of Canadian dollars; Supply of Euro = Demand for Canadian Dollars **Supply of foreign exchange (Demand for CAD)** = increases if Canadian exports increases , Canadian asset sales (capital inflows) increases and Reserve currency (like savings account): If exchange is above 1.5 = excess supply of foreign exchange (high demand on CAD; pressure for \$CAD to appreciate ![](media/image2.png)Activities that increase foreign currency supply = exports, assets sales (capital inflow) and reserve currency **Demand for foreign exchange (Supply of CAD)** = is negatively sloped; if \$CAD depreciates against Euro; Canadian dollar price rises of European goods rises; Canadian will buy fewer European goods; Amount of foreign exchange is being demanded by Canadians to pay for imported European goods will fall A **depreciation** of \$CAD = **increase the supply** of foreign currencies (more people want to buy Canadian goods A **appreciation** of \$CAD = **increase demand** for foreign currencies (Canadians want to buy foreign goods) **Flexible exchange rate** = when central bank makes no transaction in the foreign-exchange market **Fixed exchange rate (or pegged exchange rate)** = when central bank intervened on the foreign exchange market to "fix" or "peg" the exchange rate at a particular value = capital inflow will \$CAD appreciate the currency of the capital-importing nation. **Exchange rate often respond to changes in the price of import and exports**: A rise in foreign prices of Canadian imports = causes \$CAD to appreciate or depreciate, depending on the elasticity of demand If Canadian demand is **elastic** = if price of foreign of imports increase = Canada will import less =\> demand for foreign currency shift left =\> exchange rate decrease = \$CAD value appreciate If Canadian demand is **inelastic** = if price of foreign of imports increase = Canada will import increase =\> demand for foreign currency shift left =\> exchange rate increase = \$CAD value depreciate Higher inflation = depreciation **Short term capital movement** **Cause of Current Account deficits** (CA = (Saving -- Investment) + (Taxes -Government purchases)) **Purchasing power parity** (e^ppp^ (exchange rate of \$CAD to foreign currency) =P~C~ (price level of Canada) / P~E~ (price level of foreign country)) = price level relation between 2 countries **Neo-mercantilists** = argue, the benefit of international trade [increase in the size of the trade surplus]; the power of the government is related to the size od the trade balance; the country's living standard is related to the size of the trade surplus They believe that a country's gains from trade arise from having exports exceeding imports **Fractionally backed** = banks have many more claims outstanding against them than they have in reserves available to pay those claims; The major problem with a fractionally backed currency was maintaining its convertibility into the precious metal behind it **Type of unemployment**: frictional (due to turnover and job change); structural (mismatch between labor force and characteristic and available jobs); cyclical (business cycle) If cyclical unemployment is positive = means recessionary gap **NAIRU** (U\*) = Natural rate of unemployment, also non-accelerating inflation rate of unemployment also full employment but mean when we at Y\* (potential GDP) **NAIRU = Frictional + structural** **actual unemployment rate (U)** = NAIRU + cyclical Actual unemployment \> NAIRU = Recessionary since more people unemployed Actual unemployment \< NAIRU = inflationary **Output Gaps:** Y\>Y\*, inflationary = wages rise; Y\ Recession - \> Wages go down Prices: changes in wages affect Aggregate Supply (AS), shifting the price level;if wages increase, AS shift left (inflationary) = high prices; if wages decrease, AS shift right (recessionary) **Actual inflation** = [Output-gap inflation + Expectation inflation] + supply shock inflation [Output-gap inflation] (up and down caused by output gap) [ and Expectation inflation]= inflation caused by wages **Expected inflation** = anticipated rate of inflation in the future (also called exceptional effect) **Supply-shock inflation**= other then wages such as increase in price of oil will be bad for Canadian business therefore AS will shift left **Constant inflation** = no output gap effect on wages and no supply shock inflation; Actual inflation = expected inflation **Constant inflation** = maintained though monetary expansion (Money Supply (MS) increases so AD shift right) \[MS increasing = cause [interest rate] to go [down] because bank have [more money] and can afford to loan it a [cheaper interest rate]; AD will go up. People have more to spend\]; AS does not get affected by any Aggregate expenditure (AE), interest, money supply = monetary policy, only affect demand; AS and AD both shift equally to maintain equilibrium Y (if AE goes up= AD will go up) If **monetary expension = MS ↑ = i↓ = AD↑** **Hysteresis** **Inflation targeting =** **Adjustment process** (AS) = prices to adjust in response to output gaps + Tech. / fac. Supplies = constant **Excess demand** = qty demanded \> qty supplied **Excess Supply** = qty supplied \> qty demanded **Overnight interest rate =** rate that bank charges in each (such as CIBC to TD); if Canada reduces its target inflation= overnight interest rate will go down = AD shift right; if higher overnight interest rate = interest of economy will go up **Demand inflation (Positive Demand Shock)** = shift AD t o right and lead to higher price level and Y\>Y\*; positive demand shock when AE function elements increase ( AE = C + I +G + X -IM( IM goes down) **Supply inflation (Negative Supply shock)** = increase price of input If AD positive and AS negative (vise-versa) = Real GDP undetermined but not the price level) If AD and AS negative = decrease in Y but cannot determine price level **Accelerating inflation** = acceleration hypothesis = Y\> Y\*; cause inflation to accelerate; happens when Central bank use monetary policy; example: expansionary policy used during inflation gap **Disinflation =** reduction in rate of inflation**; 3 phases** 1. **Remove monetary policy** (stop expansionary policies and start contractionary polices; slows o stops the shift od AD to the right) 2. **Stagflation** (occurs when slow economic growth, high inflation, and rising unemployment; occurs as AS continues to shift upwards due to inflation expectations, leading to reduction in output and rising prices) 3. **Recovery** (Scenario 1 \[no monetary validation\] = market adjust itself (adjustment process), wages fall slowly, AS shift right and recessionary gap is closed; Scenario 2 \[one time monetary validation\] = Central bank start expansionary policies again to increase MS, shift AD to the right, and recessionary gap is closed) **Cost of Disinflation;** loss of economic activity and rise in unemployment **Sacrifice ratio =** % of Y that is sacrificed for % point of inflation reduction \[sacrifice ratio = (% loss in GDP/decrease inflation) \* 100\] ; We want lower ratio because we want to sacrifice less GDP = cost of disinflation **Fiscal stabilization policy =** **Automatic fiscal stabilizer** **Employment and unemployment** **Unemployment rate** = unemployed/labour force (employed + unemployed) **Avg. duration of unemployment spell** = stock of unemployment (people unemployed at a specific time)/monthly outflow from un employment (people moving out of unemployment and into employment or leaving labor force) **Marketing-clearing =** wage is perfectly flexible; labour market clear quickly; Y return to Y\*; U=U\*; there is no involuntary unemployment (caused by frictional or structural reason and voluntary **Non-marketing-clearing =** wages are sticky; unemployment = involuntary (recession -\> called cyclical unemployment (happen when wage is above market clearing (equilibrium wage)) **Excess supply = above equilibrium and excess demand = below equilibrium** **Reducing Cyclical Unemployment =** Expansionary Monetary **\[in a recession = MS increase; interest go down; AD goes up\]**and fiscal (lower taxes and/or increase government purchase; AD will go up )policies **-(**Increase government spending**;** Decrease taxes**;** Decrease interest rate **or** Increase the money supply) **Reducing Frictional Unemployment=** Decrease benefits of unemployment insurance program**;** Create a national job bank to show available jobs across the country **Reducing Structural Unemployment =** Programs to retrain and relocate individuals **Government Debt and deficits** **Debt** = accumulation of past deficits; **deficits** = annual shortfall between revenues (money from taxes) and disbursements (government spending \[G + i\*D\] **Budget constraint**- government raises money with tax revenue or borrowing; spending includes purchases and interest payments on debt.
