ECON - Money, Banking, and Firms, and Exam Strategy

Money and the Barter System

• Money is defined as anything that is generally accepted as a medium of exchange for goods and services.

• In simple terms, money removes the necessity to directly trade goods for other goods.

The Barter System

• Historically, before the existence of money, individuals utilized the barter system.

• Barter is defined as the direct exchange of goods and services without using money as a medium.

• Problems associated with the barter system include:

  • The Need for Double Coincidence of Wants: Inefficiency arises because both parties must simultaneously desire exactly what the other has to offer.

  • Lack of a Common Measure of Value: There is no standardized way to express the value of different items.

  • Difficulty in Storing Wealth: Goods used in barter are often perishable and can spoil, making it hard to save value for the future.

  • Indivisibility: Certain goods cannot be easily split into smaller units for lower-value transactions.

How Money Solves Barter Problems

• Acts as a universal medium of exchange.

• Provides a standard measure of value through the establishment of prices.

• Can be easily stored and is durable over time.

• Is divisible into smaller units to facilitate various transaction sizes.

Functions and Characteristics of Money

The Four Functions of Money

• Medium of Exchange: It is used specifically to buy and sell goods and services.

• Store of Value: It can be saved, retaining its purchasing power to be used in the future.

• Unit of Account: It provides a standardized way to measure the value of items (expressed as prices).

• Standard of Deferred Payment: It is used as the basis for paying debts at a future date.

Characteristics of Good Money

• Durable: It must last a long time without physically degrading.

• Portable: It must be easy for individuals to carry around.

• Divisible: It must be capable of being split into smaller denominations.

• Acceptable: It must be trusted and recognized by everyone in the economy.

• Limited Supply: The supply must be controlled to ensure the money maintains its value over time.

Banking Institutions

• A bank is a financial institution that accepts deposits, provides loans, and offers various financial services.

Types of Banks

• Central Bank:

  • Examples: Bank of Jamaica or the Bank of England (UK).

  • Functions:

  • Controls the national money supply.

  • Issues the official national currency.

  • Acts as the banker to the government.

  • Functions as the lender of last resort to commercial banks.

  • Controls interest rates and manages inflation.

• Commercial Banks:

  • Examples: National commercial banks and private banks.

  • Functions:

  • Accept deposits from the public.

  • Issue loans to individuals and firms.

  • Provide savings accounts.

  • Offer financial products such as credit cards and overdrafts.

• Credit Unions:

  • These are owned by their members.

  • They are usually established for specific groups of workers or communities.

  • They offer savings and loan services at lower rates than commercial banks.

• Mutual Societies:

  • These are owned by their members (who are also the customers).

  • Their primary focus is on savings accounts and providing mortgages.

• Investment Banks:

  • They assist businesses in raising capital.

  • They deal specifically with shares and bonds.

  • They advise corporations on various investment strategies.

• Islamic Banks:

  • These institutions operate according to Islamic law (Sharia), which prohibits interest ($riba$).

  • They utilize profit-sharing mechanisms instead of traditional interest rates.

Comparison: Central Bank vs. Commercial Banks

• Central Bank: Controls the economy; Commercial Banks: Serve individual and business customers.

• Central Bank: Issues national currency; Commercial Banks: Give loans to customers.

• Central Bank: Controls inflation; Commercial Banks: Accept deposits from the public.

• Central Bank: Functions as the government's bank; Commercial Banks: Function as private or public firms seeking profit.

Households, Workers, and Firms

Households

• Households consist of individuals or families that consume goods and provide factors of production.

• Households earn income from four primary sources: wages, rent, interest, and profit.

• They spend money on goods and services and save money within the banking system.

Influences on Household Spending

• Income: Higher levels of income typically lead to higher levels of spending.

• Interest Rates: High interest rates encourage more saving and reduce the incentive to borrow money.

• Consumer Confidence: If individuals feel secure about their future economic prospects, they spend more.

• Taxes: Higher tax rates reduce the amount of disposable income available for spending.

• Expectations: If prices are expected to rise soon, people often spend more in the present to avoid future costs.

Savings and Borrowing

• Saving: Defined as the portion of income that is not spent on consumption.

• Borrowing: Defined as the act of taking loans from banks to finance current spending.

Workers and Trade Unions

• Workers supply their labour to firms in exchange for wages.

• A Trade Union is an organization dedicated to protecting the rights of workers.

• Roles of Trade Unions:

  • Negotiating wages with employers.

  • Improving workplace safety and working conditions.

  • Protecting job security for their members.

  • Providing legal support to employees.

• Reasons for Joining a Union:

  • Achieving higher wages through collective bargaining power.

  • Ensuring better safety conditions.

  • Protection against unfair dismissal.

• Disadvantages of Trade Unions:

  • They can lead to higher labour costs for firms.

  • Their activities can result in industrial strikes.

  • They may reduce the overall competitiveness of a firm.

Production Sectors and Mergers

Firms and Economic Sectors

• Firms are organizations that produce goods and services with the objective of making a profit.

• Primary Sector: Extracts raw materials from nature (e.g., farming, fishing, mining).

• Secondary Sector: Involved in manufacturing goods (e.g., factories, construction).

• Tertiary Sector: Provides services to the public and other businesses (e.g., banking, education, healthcare).

Mergers

• A merger occurs when two separate firms join together to form a single entity.

• Horizontal Merger:

  • Occurs between firms in the same industry.

  • Example: Two smartphone companies merging.

  • Benefits: Increased market share and achievement of economies of scale.

• Vertical Merger:

  • Forward Vertical: A firm merges with its distributor.

  • Backward Vertical: A firm merges with its supplier.

  • Benefits: Better control over the supply chain and reduced production costs.

• Conglomerate Merger:

  • Occurs between firms in completely different industries.

  • Example: A food company merging with a bank.

  • Benefits: Diversification of interests and reduced overall business risk.

Exam Strategy and Command Words

• Define / Identify ($2 \text{ marks}$):

  • Should be short and precise.

  • No further explanation is required.

  • Example: "Define scarcity." Answer: "Scarcity is when resources are limited but wants are unlimited."

• Explain ($4 \text{ marks}$):

  • Structure requires a definition plus one well-developed point.

  • Example: "Explain why demand falls when price increases." Answer: "Demand falls when price increases because consumers cannot afford as much, so they buy less of the product, reducing quantity demanded."

• Analyse ($6 \text{ marks}$):

  • Requires a chain of reasoning ($\text{A} \rightarrow \text{B} \rightarrow \text{C}$).

  • No conclusion is needed.

  • Example: "Analyse how a fall in price increases demand." Answer: "A fall in price makes a good cheaper, which encourages consumers to buy more, increasing quantity demanded, which increases total sales for firms."

• Discuss ($8 \text{ marks}$):

  • Structure requires Advantages ($2$ to $3$ points), Disadvantages ($2$ to $3$ points), and a final judgement.

  • Example: "Discuss whether government should increase taxes on cigarettes."

  • Pros: Reduces smoking and improves public health.

  • Cons: Reduces government revenue from other goods and may lead to illegal trade.

  • Judgement: Depends on whether the health benefits outweigh the potential revenue loss.

Unit 3 Summary

• Money serves as a replacement for the barter system, solving its inherent inefficiencies.

• Banks are responsible for managing money, issuing loans, and maintaining economic stability.

• Households are the basic economic units that earn, spend, and save income.

• Workers supply the necessary labour for production and may join trade unions for protection.

• Firms produce goods across the primary, secondary, and tertiary sectors.

• Mergers serve as a mechanism for firms to grow and reduce market competition.

• Government and central banks play a critical role in influencing the stability of the economy.
