(a) Explain two reasons why the demand for primary goods might be price inelastic. [10 marks]

Primary goods are raw materials and agricultural products that are used in the production of finished goods. These could be considered price inelastic which means that the goods are not sensitive to price changes because there aren’t any alternative goods.

Both for producers and consumers they must use these products. Since primary goods are the first sector of production there is no substitute for them.

Another reason why is the fact that these goods are necessary. For example rice is a good that millions of people eat everyday. It is an easy source of carbs and is cost effective, although there are some substitutes there is no “perfect” substitute for the good hand therefore people would still buy rice even if the price were to rise.

(b). Using real world examples, evaluate the importance of income elasticity of demand for a business selling a good if incomes are rising. [15 marks]

Income elasticity of demand is defined as a measure of how responsive the quantity demanded of a good is to change in consumer income. YED (income elasticity of demand) is important for businesses to understand in order to be able to strategize when incomes are rising. There are three types of goods: luxury, normal, and inferior. Demand for luxury goods are the ones that increase most when income rises but it is also the one most affected by price. A real world example would be Tesla which is a car brand in the luxury sector. This means that the YED is greater than one, which means that the good is not essential and demand can be affected by price. With increasing incomes there has been a boost in demand for Tesla's products. This allows for two main things to happen: expansion and diversification. More demand which increases sales allows for Tesla to scale their production and capitalize on people wanting to enter into the luxury market with higher incomes. As well as this it also allows for diversification in products. With new customers to appeal to, expanding the product line would be a great way to entice new customers to buy goods from the company.

Price inelasticity: (Horizontal) The product or service where the price does not change even if supply or demand goes up or down

Demand Inelasticity: (Vertical) Products whose demand is higher from consumers, no matter if price increases or decreases demand will stay the same

Luxury, Primary, Inferior good- define: A luxury good is a product where demand increases significantly as income rises. Primary goods are basic necessities considered for survival. Inferior goods are products where the demand decreases as income increases

(a) Distinguish between price elasticity of demand (PED) and income elasticity of demand (YED)? [10 marks]

Price elasticity of demand is defined as the measure of responsiveness of the quantity demanded of a good or service to change in its price. Whereas Income elasticity of demand is defined as the responsiveness of the quantity demanded of a good or service to change in consumer income. In other words one is measured by price changes while the other is measured by the response to income changes. One focuses on the price variations and the other on income variation.

(b) Using real world examples, discuss how firms can use price elasticity of demand (PED) and income elasticity of demand (YED) analysis to increase their sales revenue. [15 marks]

Depending on the nature of a good, a company should be able to plan accordingly in order to increase their sales revenue. In the case of an inelastic good which price increases lead to a proportionately smaller decrease in quantity demanded firms could raise their prices. For example pharmaceutical companies raise their prices on life saving drugs often because due to their inelastic demand firms can significantly increase their revenue. For price elastic goods price reductions lead to a larger increase in quantity demanded increasing total revenue. This has been seen often through Ryanair, a low cost flight company through their discounts during off season to attract consumers and increase their sales during off season. For goods with a YED more than 0 like normal goods and luxury goods their demand increases as incomes rise. Firms

(a) Explain with a diagram how the government imposition of a specific tax could reduce pollution levels in a city. [10 marks]

Governments can impose specific taxes to reduce pollution levels in a city. This is a form of government intervention which is the way in which a government regulates or interferes with the various activities or decisions made by individuals or organisations within its jurisdiction. This can be done through indirect and direct taxes. Indirect taxes is a tax that is levied on goods and services, and is passed on to the consumer by the manufacturer or supplier. A direct tax is one that the taxpayer pays directly to the government. Pollution is considered a negative externality of production meaning When the production process of a good or service generates a negative effect on a third party or on society as a whole. For example steel production is a significant contributor to air pollution. If a government were to impose taxes on the steelmaking industry to reduce emissions.

(b) Evaluate the effectiveness of indirect taxes in reducing the consumption levels of demerit goods such as tobacco, gasoline, and alcohol products? [15 marks]

Indirect taxes is a tax that is levied on goods and services, and is passed on to the consumer by the manufacturer or supplier. Indirect taxes are often imposed on demerit goods - a good or service whose consumption is considered harmful to the consumer and society- by the government in order to reduce consumption levels. This is often seen with tobacco, alcohol, and gasoline products. The effectiveness of this government intervention is put into question.

Negatives:

When the good is addictive, such as cigarettes, its demand tends to be price inelastic and an increase in price will not reduce the quantity consumed very much.
If taxes are raised too much, consumers might look for other illegal sources of supply, causing black markets to appear.
Taxes make people pay for the external cost they create but do not stop the negative effect from taking place, as there will still be people using or consuming the good.

-----

(a) Explain two reasons why governments might impose an indirect tax on demerit goods. [10 marks]

Two reasons for a government to impose an indirect tax on a demerit goods would be to discourage consumption and internalize negative externalities.

(b) Using real-world examples, discuss the view that government subsidies given to agricultural producers will always be beneficial to stakeholders. [15 marks]

-----

(a) Explain two ways environmental problems may lead to market failure. [10 marks]

Scarcity for resources(For example, flooding might destroy crops, causing food supplies to drop and prices to rise. This means the market doesn’t work well because it can’t provide enough affordable goods, especially for poorer people.)
Damage to natural resources( Disasters like deforestation or hurricanes can destroy natural systems that help people, like forests cleaning the air or wetlands preventing floods. When these services are lost, society pays extra to replace them, but the market doesn’t consider these costs, leading to overuse of resources and underinvestment in protecting them.)

(b) Using real-world examples, evaluate a range of strategies governments can use to help solve the market failure associated with environmental problems. [15 marks]

Subsidies

Market failures in envrionmental issues, such as pollution, occur when the market does not account for external costs (negative externalities) imposed on society.

Example: Germanys energy transition policy provudes subsidies for renewable energy, encouraging investment in wild, solar, and other green tech.

Adv: Promotes innovation and the development od sustainable technology, Reduces reliance on fossil fuels

Dis: Fiscal cost to the government, and poorly targeted subsidies may lead to market distortion.

Carbon Taxation

Sweden’s carbon tax, taxes carbon emissions from fossil fuels, incentivizing businesses and consumers to reduce carbon footprint.

Adv: It provides a market based solution, allowing firms to find the most cost-efficient ways to reduce emissions. It also generates government revenue that can be reinvested in environmental projects

Dis: Regressive in nature, affecting lower-income households disproportionately. Potential political resistance from carbon intensive industries.

A carbon tax correcrs the makret failure by imposing a cost on negative externalities(when an individual's consumption of a good generates a negative effect on third parties who were not factored into the decision to consume that good), internalizing the social cost of carbon emissions and encouraging a shift to greener technologies.

(a) Explain, using an appropriate diagram, how the market for pasta would be affected given a new and successful advertising campaign announcing greater health benefits coming from eating pasta. [10 marks]

Increased demand
Price elasticity of demand-A measure of the responsiveness of the quantity demanded of a good or service to a change in its price.
Non-price determinant
Price signals: demand increases, so does supply
Increased demand will increase the price

When an advertising campaign announces greater health benefits from Pasta, it acts as non price determinant of demand, influencing cosnumer preferences. More consumers are likely to purchase pasta at every price level due to the increase in demand.

Diagram: Price elasticity of demand: Increase in demand because of a successful advertising campaign. More consumers are willing to buy pasta at any given place. Rightward shift in demand curve. The increase in demand causes a higher P2, which serves as a price signal to producers. The higher price encourages producers to increase supply, thus moving along the supply curve. As price increases, producers supply more pasta to the market, and if it is responsive, then this may lead to an increase in quantity demanded at a new higher price.

PED: If demand is elastic, consumers will respond significantly to the change in price. Pasta would be elastic since you can buy a substitute like rice and the demand would change due to non-price determinants(Goods can be substitutes for each other, complementary to each other or not related at all. When they are related in some way, a change in the price of one will result in a change in the demand of the other)

Real world example: In 2006, there was a study about coffee consumption having a reduced risk of certain diseases. There was then an increase in consumer demand for coffee as people were willing and able to pay for it because of the health benefits. Coffee shops and brands saw an increase in demand and sales and many promoted this and their advertising.

The market adjusts to this by increasing the demand of pasta and incentivizing producers to increase output. Overall effect of the campaign will be higher prices and quantities sold. This would also be negative for competitors or pasta substitutes (like rice) as their demand would go down.

(b) Using real-world examples, discuss the available options that a government has to regulate consumer demand. [15 marks]

Trends, substitutes(find out if pasta has more health benefits than rice you gonna buy it)

Rice price is lower so demand goes down and for pasta demand goes up as price goes up because it has more health benefits.

The government wants to regulate it because it might hurt the rice industry

Governments can use several strategies to regulate consumer demand in markets where shifts might negatively impact certain industries.

Subsidies for rice: The government can provide subsidies for rice producers to lower production costs and reduce the price of rice. This would make rice more competitive against pasta, curbing the demand for pasta, for example, India has long subsidized rice via public distribution systems to keep prices low for consumers, encouraging consumption, especially in rural areas where rice forms the core of peoples diet.

Subsidies are financial aids given to consumers or producers to encourage the consumption or porduction of certain goods. They are used to increased demand for products that governments want to promote.

Advantages: Subsidies help ensure that everyone has access to basic necessities, regardless of income. Subsidies can improve overall welfare of society by helping to improve standard of living and reduce inequality by making food and other products affordable. Can also help stabilize prices for essential goods and services, preventing extreme price fluctuations caused by facotrs like supply chain disruptions.

Disadvantages: Subsidies can become costly for governments, Inefficiencies arise when subsidies are nit well-targeted. They can benefit the wealthy or large corporations rather than the intended low-income consumers. This can lead to misallocation of public funds. Can also lead to overconsumption of goods.

Solutions: Targeted subsidies rather than the entire population, Reduce subsidies over time to reduce fiscal burden, improve data and technolgy

(a) Explain why the under-provision of a public good by a free unregulated market is an example of market failure. [10 marks]

Common pool resource( A diverse group of natural resources that are non-excludable, but

their use is rivalrous, for example, fisheries.)

The under-provision of a public good in a free unregulated market is an example of market failure because of the inherent characteristics of public goods- non excludable and non-rivalry. Non-excludable means that once a public good is provided, individuals cannot be excluded from using it, and non-rivalry means one person’s consumption does not reduce the availability for others. These characteristics lead to the free rider problem, where individuals have an incentive to benefit from the good without paying for it, causing producers to undersupply it. Since firms cannot exclude non-payers, they are unwilling to produce enough of the good, as they cannot make a profit.

EX: Nation defense: Governments provide national defense services because private firms would struggle to supply it adequatley, as indivduals can benefit from national security without contributing to it's cost, leading to under-privision in a free market economy. As a result, governments intervent to ensure the adequate supply of such goods, correcting the market failure.

(b) Discuss, using real world examples, whether the direct provision of a public good is the most effective way of correcting the market failure of public goods. [15 marks]

Government says it is not being provided enough. We don’t have affordable housing so the government just buys you the house. Can lead to price ceiling/floor

The direct provision of public goods by the government is often seen as a solution to the market failure caused by the free rider problem, where goods are non-excludable and non-rivalrous, meaning individuals cannot be excluded from using them, and one person's consumption doesn't reduce availability for others. A key example is street lighting, which is funded by taxes and provided by local governments, ensuring that everyone benefits from improved safety without excluding anyone. The advantages of direct provision include equitable access for all members of society, regardless of income, and the ability to correct under-supply in the private market. However, disadvantages include the high fiscal costs borne by taxpayers, and potential inefficiency due to bureaucratic management. For instance, local government-run street lighting may be subject to slow decision-making or over-provision in some areas. Solutions to these issues include public-private partnerships (PPPs), where the government funds the good but private companies provide the service, ensuring both efficiency and wide access. Additionally, targeted user fees or congestion charges in areas where services are overused could help alleviate the fiscal burden while maintaining universal access

(a) Explain why an unregulated market uses common pool resources in an unsustainable manner. [10 marks]

(b) Discuss, using real world examples, what kind of intervention is the most efficient policy to reduce a negative consumption externality. [15 marks]

(a) Reasons for Price Inelasticity of Demand for Primary Goods

Lack of Substitutes: Primary goods, such as raw materials and agricultural products, are essential because they do not have close substitutes. For both producers and consumers, these goods are critical for production and consumption, respectively.
Necessity: Many primary goods are necessary for survival. For example, rice is a staple food consumed by millions daily. Although there are some alternatives, none can completely replace rice for its affordability and nutritional value. Thus, even if prices rise, people will continue to buy it.

(b) Importance of Income Elasticity of Demand (YED)

Income elasticity of demand measures how sensitive the quantity demanded of a good is to changes in consumer income. Understanding YED is crucial for businesses, especially when incomes rise. There are three types of goods:

Luxury Goods: Demand increases significantly with rising income, but they are also sensitive to price changes. For example, Tesla, a luxury car brand, experiences a boost in demand as incomes increase, allowing expansion and diversification of products.
Normal Goods: Demand increases moderately with rising incomes.
Inferior Goods: Demand decreases as incomes rise.

Understanding these distinctions helps businesses strategize effectively as market conditions change.

Price and Demand Elasticity Definitions

Price Elasticity of Demand (PED): The measure of how much the quantity demanded of a good changes in response to a change in its price.
Income Elasticity of Demand (YED): The measure of how much the quantity demanded of a good changes in response to a change in consumer income.

(a) Price Elasticity vs. Income Elasticity

PED: Focuses on how price changes affect demand.
YED: Focuses on how income changes affect demand.

(b) Using Elasticity to Increase Sales Revenue

Businesses can analyze both PED and YED to improve sales:

For inelastic goods, companies can raise prices without significant loss in demand, like pharmaceutical firms increasing prices on essential drugs.
For elastic goods, lowering prices can attract more consumers, as seen with budget airlines like Ryanair, which offer discounts to boost demand during off-peak seasons.

Government Intervention in Pollution

Specific Taxes: Governments can impose taxes on industries causing pollution to discourage harmful practices. For instance, taxing the steel industry can incentivize them to reduce emissions.

Effectiveness of Indirect Taxes on Demerit Goods

Advantages: They can decrease demand for goods like tobacco and alcohol, which have negative effects on consumers and society.
Negatives: Addictive goods may see inelastic demand, meaning price increases may not significantly reduce consumption. Additionally, high taxes can promote black markets.

Reasons for Indirect Taxes on Demerit Goods

Discourage Consumption: Taxes can reduce demand for harmful products.
Internalize External Costs: Taxes can help cover the societal costs caused by consumption of demerit goods.

Environmental Issues Leading to Market Failure

Resource Scarcity: Natural disasters can reduce resources, leading to higher prices and unavailability.
Damage to Natural Resources: Destruction of ecosystems decreases their value to society and leads to overuse of remaining resources.

Government Strategies to Solve Market Failures

Subsidies: Government support can help encourage investment in renewable energy and technologies to prevent pollution.
Carbon Taxation: Imposing taxes on carbon emissions encourages businesses to reduce their environmental impact.

Effects of Advertising on Demand

Successful advertising can significantly shift demand for products like pasta, leading to a price increase. This occurs as consumers are drawn to the perceived health benefits, altering buying patterns and prompting producers to increase supply in response to higher demand.
