Lecture Y Movement of Economy Around the Trend: A Reminder million unemployed in the OECD Recession Boom

Lecture 94 Needs for Stabilisation: Costs of Inflation Inflation distorts relative prices and makes the market system less efficient as prices cannot signal relative scarcity Inflation transfers resources from creditors to debtors Redistributes income from fixed income group to property holders Taxes are not indexed for inflation, low income families are pushed up to the tax threshold Shoe leather and bookkeeping costs rise with inflation It creates uncertainty. Creates illusions, confusions and complicates economic calculation It is harmful for economic growth; reduces saving and investment activities It create social tension

Lecture 95 Needs for Stabilisation: Costs of Unemployment Loss of output and income and utility Personal psychological costs –Unhappiness –Stress and tension –Discouragement and disappointment –Morale and motivation –Uncompetitive feeling –Dignity of human life –Insecurity Loss of productive skills productivity Lack of learning by doing opportunity Rise in social unrest and crimes

Lecture 913 Natural Rate of Unemployment Hypothesis

Lecture 914 Four Main Theories of Natural Rate of Unemployment 1. Search cost and job mismatch theory: s = job separation rate f = job finding rate u = unemployment rate 2. Insider-Outsider theory: Inefficient Bargaining between firms and workers Members of the union demand higher wages and non-member remain unemployed 4. Rigidity in the labour Market: Minimum wage laws Entry deterrence and labour market standards 3. Efficiency wage theory Firms pay higher wages to workers to reduce hiring and firing costs and to reduce shirking and the monitoring costs or to appear as an ideal employer but that makes others unemployed

Lecture 917 Inflation is a Monetary Phenomenon

Lecture 918 Standard Measures of Stabilisation Control of Aggregate Demand –Increase or decrease in money supply –Control in the tax and spending programme –Monetisation or contraction of the budget deficit Aggregate supply –Wage renegotiations –Efficiency enhancing measures Trade and Exchange Rates Measures –Appreciation or depreciation of the currency –Trade and exchange rate agreements
