  1. Micro & Macro Economics

  2. Micro Economics • Definition - Studying a part of economy, a unit or particular, specific aspects • Characteristics: • Study of individual • Determination of individual prices • Small variables • Immediate disposal of the problem • Immediate decisions are possible

  3. Need and Significance • Essential for understanding total economic system • Helpful in- solving of economic problems • Deciding economic policy • Economic decision of individual unit • Enquiring about economic welfare Scope: • Theory of Product Pricing • Theory of Factor Pricing • Theory of economic welfare

  4. Limitation: • Study of industrial units only • Unrealistic assumption • Study of a part of economy only • Few specific problems only • Limited study of economic problems Macro Economics: • Studying aggregates • Study of whole economy system • Study of total

  5. Need and significance: • Formulation and successful of economic policy • Regulation and control of entire economy • Study large and complex developing micro economics, tracing of economic problems Scope: • Theory of Income • Output and employment • Theory of Prices • Theory of economic growth and development • Theory of distribution Limitation: • Aggregative study, • Conclusions on mass level, • No Means for Industrial units, • Complex study.

  6. ECONOMIC LAW

  7. ECONOMIC LAW Meaning of economic laws: “Belonging to economic field, applicable throughout the world” Characteristics: • Statement of economic tendencies, • Absolute, social, • Based on imagination, • Concerned with monetary measurement

  16. Type of elasticity of demand: Income elasticity of Demand: related to disposable income Type of Income Elasticity of Demand: • Zero • Negative • Positive Price Elasticity of Demand: Proportionate change with quantity to change in price, Ratio of change in quantity to change in price Methods of Measuring Price Elasticity: • Total outlay or expenditure method • Point Method • Arc Method

  17. Cross Elasticity of Demand: Measurement of change in demanded quantity to change in price Type of Cross elasticity of demand: • Zero, • Negative, • Positive:(a) >1 (b) <1, (c) =1 • Infinitive

  18. Factors governing the elasticity of demand: • Number and closeness of substitutes • Significance of commodity in budgets • Degree of necessity of goods • Habits and temperaments of consumer • Number of the use of commodity • Period of time for demand Demand: • Effective desire, • Means to fraction • Willingness
