Question 1: Decision-Making in Higher Education Using Marginal Analysis

Economists view decision-making through the lens of rational choice, where individuals weigh the benefits and costs of their actions to maximize utility. When considering higher education, an individual evaluates whether the benefits derived—such as increased earning potential, personal development, and social opportunities—justify the costs, including tuition, time, and effort. This process aligns with marginal analysis, which involves comparing the additional (marginal) benefits of pursuing higher education against the additional costs. Rational decision-making occurs when the marginal benefit equals or exceeds the marginal cost, leading to an optimal choice.

Applying marginal analysis to higher education entails estimating the marginal increase in lifetime earnings attributable to a college degree versus the marginal costs incurred, such as student loans and foregone income during study years. An individual makes a rational decision when the net benefit is positive, indicating that the additional gains outweigh the additional costs.

The statement "Higher education is priceless, so everyone should pursue a degree no matter the cost" is irrational from an economic perspective. If education truly has infinite value, then the marginal benefit of an additional degree would be infinite, which is unrealistic. Rational decision-making requires individuals to compare marginal benefits and marginal costs; if the costs outweigh the benefits, pursuing further education is not justified. Moreover, not everyone values education equally, and the opportunity costs vary depending on individual circumstances. Therefore, making a universal claim that no cost should be a barrier ignores the scarcity of resources and the importance of marginal analysis. Rational choice thus involves assessing whether the additional benefits of higher education justify the additional costs in each individual's context.

Question 2: Absolute and Comparative Advantage in a School Project

Suppose you and your partner are working on a school project requiring both math and writing skills. If you are better than your partner at both math and writing — meaning you have an absolute advantage in each — the decision of responsibility allocation depends on comparative advantage.

Absolute advantage refers to the ability to produce a good or service more efficiently than someone else. In this case, you can perform both tasks more efficiently than your partner. However, comparative advantage considers opportunity costs — that is, what you forego when choosing to produce one good over another.

If your opportunity cost of doing math is lower than your partner’s, and your opportunity cost of writing is also lower than your partner’s, then you have a comparative advantage in both tasks. This would suggest you should handle both parts, maximizing efficiency. Conversely, if your opportunity costs differ, even though you are better in absolute terms, it might be more efficient for you to specialize in the task for which you have a comparative advantage and let your partner handle the other. This specialization allows both of you to produce more efficiently and complete the project effectively.

This illustration underscores the importance of comparative advantage in decision-making, highlighting that the most efficient allocation depends not just on absolute productivity but on opportunity costs, ultimately leading to better cooperation and productivity.

Question 3: Impact of a Self-Milking Cow Machine on Milk Market Equilibrium

The invention of a machine allowing cows to milk themselves represents a technological advancement that enhances productivity in milk production. Such innovation reduces the marginal cost of producing milk because less labor is needed, and the process becomes more efficient.

As a result, the supply curve for milk shifts to the right, indicating an increase in supply. The increased supply causes a downward movement along the demand curve, leading to a decrease in the equilibrium price of milk. Simultaneously, the higher supply results in an increase in the equilibrium quantity of milk sold in the market. Consumers benefit from lower prices, and more milk is available, stimulating overall market activity.

This scenario exemplifies how technological progress shifts the supply curve outward, increasing total output and lowering prices, benefiting consumers and potentially encouraging further innovation in the industry.

Question 4: Effect of Health Benefits News on Milk Market Equilibrium

The report stating that drinking at least 8 ounces of milk daily increases bone density by 10% over a lifetime can influence consumer behavior. Such health information acts as a positive demand shifter, increasing consumers’ willingness to buy milk due to perceived health benefits.

Consequently, the demand curve for milk shifts to the right, indicating higher demand at each price level. This shift results in a higher equilibrium price and a greater quantity of milk exchanged in the market. Consumers interested in improving their bone health will purchase more milk, leading producers to respond by increasing production to meet the increased demand.

Over time, this health-related information can stimulate the dairy industry and promote consumption, demonstrating how external information regarding health benefits can influence market demand and equilibrium outcomes.

Question 5: Externalities in Personal Life and Role of Government

An externality is a cost or benefit that affects third parties who are not involved in the original economic transaction. During my lifetime, I have experienced both positive and negative externalities.

A positive externality I benefited from was receiving free vaccinations through a community health program. The widespread immunization in my community reduced the risk of disease transmission, benefiting even those who did not get vaccinated directly. I viewed this external benefit as a contribution to public health, which has a role for government to sustain, for example, through funding and organizing vaccination programs. Government intervention here ensures the provision of positive externalities, promoting overall societal welfare.

Conversely, I have suffered from a negative externality when my neighbors improperly dispose of waste, leading to environmental pollution and health issues in my area. This external cost affects my well-being without compensation. In this case, I believe government has a vital role in regulating waste management, enforcing environmental laws, and internalizing external costs to prevent or mitigate such negative externalities. Without government intervention, the market tends to under-provide solutions for externalities because private parties do not bear the full social cost or benefit of their actions.

Overall, externalities justify government involvement to correct market failures, promote efficiency, and enhance social welfare. Policies such as taxes, subsidies, and regulations can align private incentives with society's broader interests, addressing both positive and negative externalities effectively.
