Microeconomics Basics Quiz

Dynamic Economic and Business Environment

• This is an introduction to the dynamic economic and business environment.
• Various entities analyze the business environment: economists, political scientists, sociologists, anthropologists, government policymakers, multinational and domestic firms, investors, and international lenders.

Business Environment Analysis

• Microeconomic policy covers market competition and regulation.
  • Relevant theories include public interest theory, public choice theory, and theory of regulatory capture.
  • A related concept is the tollbooth view.
• Macroeconomic policy focuses on controlling inflation, maintaining a stable exchange rate, ensuring fiscal prudence, and having stable financial markets.

What is Economics?

• Scarcity is a fundamental human dilemma, as resources are limited while wants are unlimited.
• Economics involves making choices.
• Mankiw defines economics as the study of how societies manage scarce resources.
• Hirshleifer's perspective on economics focuses on decisions—choices among various actions.
• Alternative definitions include how society allocates scarce resources to improve human welfare.

What is Economics? (Sub-topics)

• Microeconomics analyzes the behavior of individual economic units—consumers, firms, workers, and investors—and the markets that these units comprise.
• Macroeconomics deals with aggregate economic variables, such as national output, interest rates, unemployment, and inflation.

Themes of Economics: Prices and Markets

• Microeconomics explains price determination.
• In centrally planned economies, the government sets prices.
• In market economies, prices are determined by the interactions between consumers, workers, and firms through markets (which are collections of buyers and sellers).

What is a Market?

• A market is an institutional arrangement where buyers and sellers can voluntarily exchange goods or services at mutually agreeable prices.
• Markets needn't be specific places—the market for professors, for example, has no physical location.
• The law of one price dictates similar goods should have similar prices across locations.
• Arbitrage is the practice of buying at a low price in one location and selling at a higher price in another.
• Defining a market's boundaries involves considering geographic boundaries and the type/range of products produced and sold within it.

Why Managers Study the Business Environment?

• Understanding the business environment, especially when launching a new product, is important for effective decision-making.
• Key factors include public reaction to product design and performance, competition from existing players, manufacturing costs, and the effects of government regulations (like automotive emissions standards)

Demand and Supply

• The goal of studying demand and supply is to understand and predict how changing economic conditions affect market prices and production.
• The study also assesses the implications of taxes, government price controls, and incentives on production.

The Demand Curve

• A demand curve is a relationship between the quantity consumers are willing to buy and the price of the good.
• This relationship, between the quantity demanded and the price, is often represented by an equation: QD = QD(P).

The Linear Demand Curve (Graph)

• (Refer to page 14 of the slides for the visual representation.)

Other Variables Affecting Demand

• Income of consumers
• Prices of related goods.
  • Substitutes: an increase in the price of one good leads to a higher demand for its substitute.
  • Complements: an increase in the price of one good reduces the demand for its complement.
• Taste and preferences
• Changes in demand lead to shifts in the demand curve, not movements on the curve.

Shifting of Demand Curve (Graph)

• (Refer to page 16 of the slides for the visual representation.)

The Supply Curve

• The supply curve is the relationship between the quantity of a good that producers are willing to sell and the price of the good.
• This relationship is often written as an equation: Qs = Qs(P).

The Linear Supply Curve (Graph)

• (Refer to page 18 of the slides for the visual representation.)

Other Variables Affecting Supply

• Production costs (including wages, interest, and raw materials).
• Changes in supply cause shifts in the supply curve.

• (Refer to page 20 of the slides for the visual representation.)

Market Equilibrium

• Equilibrium in a competitive market occurs when the market price and quantity satisfy the conditions of market clearing.
• There are no shortages or surpluses at these prices.
• (Refer to page 21 and 22 of the slides for visual representation.)

Price Controls - Price Floor

• Governments sometimes impose price floors, a minimum price, to support producers.
• At a price floor above the equilibrium price, a surplus will arise, and the government may need to purchase the surplus.

Price Controls - Price Ceilings

• Governments can also set price ceilings—maximum prices.
• If a price ceiling is below the equilibrium price a shortage emerges.

Deadweight Loss

• Deadweight Loss occurs with imposed price controls.

Simultaneous Shifts in Supply and Demand

• When multiple influences affect a market simultaneously, the resulting effects on price and quantity will depend on the magnitude of individual shifts.

Elasticity

• Elasticity measures the responsiveness of one variable to a change in another.

Own Price Elasticity of Demand

• Measures the responsiveness of the quantity demanded of a good to a change in its price.
• Its value is typically negative.
• (Refer to page 40 for visual representation regarding the relationship to the demand curve.)

Elastic Demand Curve (Graph)

• (Refer to page 42 for visual representation.):|

Inelastic Demand Curve (Graph)

• (Refer to page 43 for visual representation.)

Extreme Elasticities (Graph)

• (Refer to page 44 for visual representation.)

Elasticities of Demand & Supply (Calculation)

• Calculation of price elasticity of demand and supply.

Short Run Vs Long Run Demand Curves (Graphs)

• (Refer to pages 48 and 49 for gasoline and automobile examples respectively)

Tax Impact on Market Equilibrium

• A tax levied on a good causes a difference between the price paid by the consumers and the price received by the producers.
• The burden of the tax depends on the relative elasticities of supply and demand.

Calculating Tax Revenue and Deadweight Loss (Numerical Example)

• Steps for calculating tax revenue and deadweight loss given demand and supply functions.

Elasticities and Revenue

• Price elasticity of demand calculation based on two scenarios of demand schedules.

Macroeconomic Environment Analysis

• Focuses on standard of living, resources, stability.

Stability Evaluation (Macroeconomic Indicators)

• Focuses on inflation, exchange rate volatility, money market volatility, fiscal deficit, government debt, foreign exchange reserves, short-term debt, and non-performing assets.

Stability Evaluation (Political Risk)

• Focuses on factors like redistribution among interest groups, democracy indices, civil liberties, functioning of government, political participation, political culture, corruption, systematic exclusion.

India's Recent Growth Experience (Graph)

• (Refer to page 110 of the slides for the visual representation).

Growth Theory: Rostow

• The five stage model describing a process of economic growth.

Growth Stimulators

• Measures taken by the government to stimulate growth.

Monetary Policy and Financial Markets Behaviour

• This segment examines financial institutions, direct and indirect financing, depository/non-depository financial institutions, and the benefits they bring to the economy (increased liquidity, transaction cost reduction etc).

Monetary Policy

• Definition, scope and objectives (economic growth and price stability).
• Central bank tools such as open market operations.

Foreign Exchange Rate

• Introduction, structure (hierarchy from central banks to consumers), determination in a free market, fixed exchange rate, and comparisons/arguments about fixed vs flexible exchange rate.
