Description
Final Exam: Study Notes Chapter 29: Why wages change - Wages and the output gap o The excess demand or supply of labour will change the amount of wages o The NAIRU is reached when GPD is equal to Y*, the unemployment rate is set equal to the NAIRU. Stands for either non-accelerating inflation rate of unemployment or natural rate of unemployment. - Wages and expected inflation - Overall effect on wages therefore is o Change in nominal wages = output gap effect + expectation effect - These two forces effect what will happen to the AS curve - Actual inflation = output gap inflation + expected inflation + supply-shock inflation Constant inflation - If inflation and monetary policy have been unchanged in several years, the expected rate of inflation will tend to equal the actual rate of inflation - In the absence of supply shocks, if expected inflation equals real inflation GDP must be the same as potential GDP - Constant inflation occurs when rate of monetary expansion, the rate of wage increase, and the expected rate of inflation are all constant Demand Shocks - No monetary validation would resolve itself - Monetary validation – continued validation turns transitory inflation into sustained inflation fuelled by monetary expansion Supply shocks - No monetary validation may take a long time to recover - Monetary Validation – the return to real GDP would be faster but end in a far higher price level Inflation - Accelerating inflation: as long as an inflationary output gap persists, expectations of inflation will be rising, which will lead to increases in actual rate of inflation. - Disinflation o Removing monetary validation o Stagflation o Recovery - The cost of disinflation is the loss of output during the period Chapter 30 Employment - Over the span of many years, increases in the labour force are more or less matched by increases in employment. Over the short term, however, the unemployment rate fluctuates a lot in the short term due to changes in labour force - Generally, over time new jobs are added at the same rate as the labour force to sustain employment as well as increase the unemployment rate - Employment usually increases during inflationary periods and decreases during recessions - The amount of activity in the labour market is better reflected by the flows into and out of unemployment than by overall unemployment - Measurement is skewed often because: o Discouraged workers o Underemployed workers - Unemployment has serious costs o Lost Output o Personal Costs Unemployment Fluctuations - Unemployment varies largely in the short term and the reason for which is separated into two broad categories - Market-Clearing theories o This theory state wages adjust instantly to clear the labour market after any AD or AS shock. Therefore, GDP is always equal to Y* and NAIRU is the unemployment rate. No involuntary unemployment. - Non-Market-Clearing theories o Long term employment relationships: long term relationships between firms and workers are important in most labour markets, and wages in such labour markets do no adjust frequently to eliminate involuntary unemployment o Economic Climate vs economic weather: variation in real wages usually occur gradually and are determined by long term climate. Change in short term weather often do not affect wages unless they are large changes NAIRU - The NAIRU is based off of two unemployment types when it equals the unemployment rate o Frictional: unemployment that results from the turnover in the labour market as workers move between jobs  Always frictional unemployment even at potential output o Structural: Unemployment caused by mismatch in skills, industry or location between available jobs and unemployed workers  Natural causes: will increase if there is increase in pace for structure of demand in labour market or there or a decrease in the pace at which labour is adapting to these changes  Policy causes - Why does NAIRU change o Demographic shifts: greater labour force participation by groups with high unemployment rates increases by the NAIRU o Hysteresis: lagged effect of economic downturn o Globalization and structural change o Policy and labour-market flexibility Reduce Unemployment - Structural: o Resisting change o Assisting Adjustment Chapter 31: The government budget constraint - Government expenditure = tax revenue + borrowing - G + I x D = T + Borrowing o G = purchase of goods and services o I x D = debt-service payments = payments that represent the interest owed on a current stock of debt - G + I x D – T = Borrowing => Delta D = budget deficit - Primary budget deficit determines how much money is spent on spending from tax revenue - Budget surplus or deficit determines the difference between tax revenue and spending The Stance of Fiscal policy - The budget deficit function: for a given set of expenditure and taxation policies the budget deficit rises as real GDP falls, and falls as real GDP rises - Changes in GDP cause a change along the budget deficit function - Structural and cyclical budget deficits: o When real GDP equals Y* there is no cyclical component to budget deficit it is just structural o The actual budget deficit can sometimes exceed or be lower than structural in different growth or recessionary periods - Changes in stance of fiscal policy is actually based on changes in structural budget deficit Debt Dynamics - Debt-to-GDP ratio is determined by delta d = x + (r-g) x d o d = debt to GDP ration o x = governments primary budget deficit as percentage of GDP o r = real interest rate on government bonds o g = growth rate of real GDP o delta d = change in dept to GDP ratio The effect of debt and deficits - crowding-out effect: the offsetting reduction in private expenditure caused by the rise in interest rates that follows expansionary fiscal policy - in our macro model we assume that an increase in the government’s budget deficit leads to an decrease in national savings - Do defici
