➤ How does a firm choose the size of its new production facility?
A firm compares expected demand and revenue to long-run costs. It selects capacity where expected marginal revenue equals marginal cost and long-run average cost is minimized, considering economies of scale. Include fixed installation costs, flexibility for demand swings, financing costs, and risk, using scenario analysis and discounted cash flows.

2. How does unemployment affect the Fed’s decision on rate hikes?
Unemployment signals slack in the economy and affects inflation pressure. High unemployment reduces wage growth and lowers inflation risk, which supports keeping rates low. Falling unemployment can raise wage inflation and push the Fed toward tightening. The FOMC examines unemployment alongside wage data, labor participation, and productivity to set policy timing.

➤ What happens to aggregate demand and short-run output when government increases defense spending?
Raising defense spending directly increases aggregate demand through higher government expenditure. In the short run, output rises as firms expand production to meet stronger demand and unemployment falls. The size of the boost depends on the fiscal multiplier, the economy’s slack, and existing monetary conditions, so the rise in GDP may be partial and temporary.

Exploring the potential of 4IR to drive economic growth, improve living standards, and solve societal problems. Question 22. Research Aim/Objectives of the above research topic.
Research Aim
To investigate how Fourth Industrial Revolution (4IR) technologies can be leveraged to stimulate economic growth, enhance living standards, and address pressing societal challenges.
Research Objectives
Identify key 4IR technologies (e.g., AI, IoT, robotics, blockchain, advanced manufacturing) relevant to economic development and social welfare.
Assess the potential impact of selected 4IR technologies on productivity, employment, income distribution, and overall economic growth.
Evaluate the effects of 4IR adoption on living standards, including access to healthcare, education, housing, and basic services.
Examine how 4IR technologies can be applied to solve specific societal problems such as poverty, inequality, environmental sustainability, and public service delivery.
Identify barriers and risks (e.g., skills gaps, job displacement, digital divide, ethical and regulatory concerns) that may hinder the positive outcomes of 4IR.
Recommend policy interventions, capacity-building strategies, and best practices for governments, industry, and civil society to maximize benefits and mitigate risks.
Develop a framework for monitoring and evaluating the socioeconomic outcomes of 4IR initiatives in different contexts.
