Assess the extent to which the time period considered (short run, long run, very long run) significantly affects the appropriate economic policy response to a period of high inflation.
The time period considered is crucial when evaluating policy responses to high inflation. The appropriate policy tools and their effectiveness differ substantially depending on whether the analysis is conducted in the short run, long run, or very long run. Short run policies often focus on demand management through monetary and fiscal measures, aiming to cool down the economy. However, these measures can have lags and may not fully address the underlying causes of inflation. Long run policies emphasize supply-side reforms, such as deregulation, privatization, and investment in human capital, to increase productivity and reduce inflationary pressures. The very long run perspective considers structural changes in the economy and the role of institutions in maintaining price stability.
Short Run Considerations:
- Monetary Policy: Interest rate hikes are a primary tool, but can risk recession.
- Fiscal Policy: Reduced government spending and/or increased taxes can curb demand.
- Lags: Policy impacts are often delayed, making it difficult to fine-tune responses.
Long Run Considerations:
- Supply-Side Reforms: Increasing productivity reduces costs and inflationary pressures.
- Wage and Price Controls: Generally considered ineffective in the long run, distorting markets.
- Inflation Expectations: Managing expectations is vital; credibility of the central bank is key.
The effectiveness of policies also depends on the specific causes of inflation. Demand-pull inflation might be better addressed with contractionary policies, while cost-push inflation might require supply-side interventions. Therefore, a comprehensive assessment requires considering the time horizon and the underlying drivers of inflation.

Question 1: Explain the difference between positive and normative statements. Illustrate your answer with examples related to government economic policy. Consider the potential problems that arise when normative statements are treated as positive facts.
Answer:
Positive statements are claims about how the economy *is* or will *be*. They can be tested and falsified through evidence and data. They are objective and avoid value judgments. Examples include: "Raising the minimum wage will lead to a decrease in employment," or "Increased government spending will increase aggregate demand." These statements can be tested using economic models, statistical analysis, and empirical evidence.
Normative statements are value judgments about how the economy *should* be. They express opinions and beliefs about what is desirable or undesirable. They cannot be proven or disproven through objective evidence. Examples include: "The government should prioritize reducing income inequality," or "It is morally wrong for some people to be poor." These statements involve ethical considerations and personal preferences.
The problem arises when normative statements are treated as positive facts. For instance, assuming that "reducing income inequality is good" is a positive fact allows for policy evaluation based on whether policies achieve this goal. However, the statement itself is a value judgement. Different people may have different views on the desirability of income inequality, leading to disagreements about policy. Treating a normative statement as positive can lead to flawed policy recommendations based on subjective values rather than objective analysis.
- Positive: Can be tested.
- Normative: Expresses opinions.
- Problem: Treating normative as positive leads to flawed policy.

Question 1: 'Economics is not simply about the allocation of scarce resources; it is fundamentally a social science concerned with human behaviour and its consequences.' To what extent do you agree with this statement? (12 marks)
Answer: This question requires a nuanced response, acknowledging both the core economic principles of scarcity and efficiency, and the crucial role of human behaviour and social context. While the allocation of scarce resources is a foundational element of economics, reducing it solely to this ignores the underlying motivations, biases, and social structures that shape economic decisions.
Arguments supporting the statement:
- Behavioural Economics: The rise of behavioural economics demonstrates how psychological factors (e.g., cognitive biases, framing effects) significantly influence economic choices, often deviating from the rational actor model. This highlights the importance of understanding human behaviour.
- Social Institutions: Economic outcomes are heavily influenced by social institutions like government, law, culture, and norms. These institutions shape incentives and constrain choices, demonstrating the social context of economic activity.
- Inequality and Power: Economic inequality is not just a matter of resource allocation; it's often linked to power structures, social hierarchies, and historical injustices. Understanding these social dynamics is essential for a comprehensive economic analysis.
- Public Policy: Effective public policy requires an understanding of social needs, values, and preferences. Economic policies are not neutral; they often reflect and reinforce existing social power relations.
Arguments against the statement (or qualifications):
- Rationality Assumption: Traditional economics often assumes rational actors, which can be a simplifying assumption. While useful for modelling, it doesn't fully capture the complexity of human decision-making.
- Mathematical Models: Economic models rely heavily on mathematical frameworks, which can sometimes abstract away from the messy realities of social life.
- Focus on Efficiency: A core aim of economics is often to improve efficiency in resource allocation. While this can have social consequences, the primary focus remains on economic performance.
Conclusion: While the allocation of scarce resources is a central concern of economics, it is insufficient to define it as solely an economic science. Economics is inextricably linked to human behaviour, social institutions, and power dynamics. Therefore, I largely agree with the statement, but with the caveat that the focus on efficiency should be balanced with considerations of social justice and equity. (12/12)
