Chapter 13 The economic environment of business of finance Flashcards
1.1 The microeconomic environment: market mechanism
The market mechanism is the interaction of supply and demand for a particular item. In particular how prices are determined by the interaction of supply and demand.
2.1 Demand
The demand for a good is the number of consumers willing and able to buy at a given price. A demand schedule or curve shows demand at each price assuming other variables are constant. Quantity demanded goes up as price falls, lower prices makes the goods more attractive. Price of the good, price of other goods, substitutes (different brands), complements, national income, fashion, population size and credit terms all determine demand.
2.3 Shifts of the demand curve
Change in price cause movements along the demand curve. Changes in other factors move the curve itself, the curve will shift right (increase in demand) if there is an increase in household income, increase in price of substitutes, decrease in price of complements, the good being more fashionable and an expectation that the price of good will be higher in the next period.
2.4 Price elasticity of demand
Looks at the degree to which demand is affected by changes in selling price. PED = % change in demand / % change in Price
Inelastic means PED is less than 1, elastic means PED is greater than one, perfectly inelastic means PED = 0, perfectly elastic means PED is infinity and unitary elasticity means PED is 1.
Factors affecting PED include:
- Availability of substitutes
- Time – short run demand tends t be less elastic but in long term more elastic
- Competitors pricing
- Nature of the product
- Proportion of income accounted for by a good
2.5 Significance of price elasticity
- Allows managers to predict the effect of price changes on demand and revenue
- Inelastic products (PED less than 1): increasing price will increase total revenue even though fewer units are sold
- Elastic products (PED more than 1): increasing price will cut total revenue and fewer units will be sold. For elastic demand the price must be cut to increase revenue
2.6 Giffen and Veblen goods
Giffen said: the price of bread increases but people still buy bread (staple), but they can no longer afford other more expensive foods, so they end up buying more bread. Veblen goods are bought for ostentation, so a higher prices makes them more exclusive and desirable.
2.7 other elasticities of demand
Income elasticity of demand (YED) looks at the degree to which demand is affected by changes in household income. YED = % change in demand / % change in household income.
- YED is more than 0 for normal goods
- YED is less than 0 for inferior goods
- YED is more than 1 for luxury goods
Cross elasticity of demand (XED) looks at the degree to which demand is affecting by changes in the price of other products. XED is the % change in demand for product A / % change in demand for price in product B.
- XED is more than 0 for substitutes
- XED is less than 0 for complementary goods
- XED is equal to 0 for unrelated goods
3.1 Supply
The supply of a good is the quantity that suppliers are willing to and able to supply at a given price. The supply curve shows supply at each price, assuming other variables are constant. The quantity usually extends as price increases. Existing suppliers produce more, and new suppliers switch to making the product.
3.2 Price elasticity of supply
Price elasticity of supply looks at the degree to which supply is affected by changes in the price. PES is the % change in supply / the % change in price.
- Perfectly inelastic supply means supply remains constant at all prices
- Perfectly elastic supply means supply is infinite at a particular price. Below this price supply drops instantly to zero
3.3 Determinants of supply
These include price of the good itself, price of other goods, price of joint products, costs, change in technology and other things like weather and harvests.
3.4 Shifts of the supply curve
Changes in price cause movements along the supply curve, as well as changes in other factors. The factors influencing elasticity of supply include:
- Market period: inelastic as changes in supply limited to availability of inventory
- Short run: can change production plans but still limited by capacity due to fixed plant and machinery
- Long run: can expand capacity, new firms can enter industry, more elastic
4.1 The equilibrium price
This is the price at which supply, and demand are equal. If the price is too high supply will exceed demand causing a surplus and the supplier will respond by lowering prices to attract more demand. If the price is too low demand will exceed supply causing a shortage, the supplier will respond by increasing prices to reduce the shortage. Eventually equilibrium is achieved with supply equal to demand.
4.2 Price regulation
Governments may intervene to try and affect prices in the market, they may have a maximum price this is to ensure essential goods are affordable and to limit inflation as part of a prices and income policy. The result is excess demand, queues, rationing and black markets.
They also may have minimum prices to protect suppliers (EU CAP, minimum wage agreements), the result is excess supply, can lead to farmers paid not to grow crops and unemployment.
5.1 Macroeconomic environment: national economy
Changes in the macroeconomic environment impact business. The national output of goods and services is measured against GDP. Fours factors are considered which generate a return: land (returns rent), labour (returns wages), capital (returns interest) and entrepreneurship (returns profit). GDP is the amount of expenditure spent on output. The level of national output is a measure of economic activity in a country.
5.2 Influences on the national economy
- The government: producing goods and services (education and health etc), purchasing goods and services, investing in capital projects (such as schools), and transferring payments from one section of economy to another (taxes to fund unemployment payments).
- Consumers: spending their disposable income on goods rather than saving. The amount spent depends on changes in disposable income and marginal propensity to consume (spend rather than save), changes in distribution of wealth, government policy (via tax and spending), development of new products, interest rates and price expectations
- Savers: investing what they choose not to spend, the amount saved depends on income, interest rates and the need for long term savings.
- Businesses: the amount they invest in capital goods which drives growth of the economy
