Section B:

Question 3: True or false questions:

• (i) An industry with two colluding firms sharing profits equally, with given cost functions and demand, should produce 12 units each.
• (ii) An agent deciding between attending a concert or theatre, based on weather probabilities, will choose the concert if the probability of rain exceeds a certain threshold.
• (iii) In a Nash equilibrium, every player must choose a dominant strategy.
• (iv) In game theory, (D, u) is the only subgame perfect equilibrium in a certain game.
• (v) Boris and Donald at a party: Boris leaving immediately yields payoff one; waiting for Donald can yield payoffs 0, 2, or 3 under different circumstances. The unique subgame-perfect equilibrium is Boris leaving right away.

Question 4: Discuss how panic buying or mass gatherings during UK lockdowns are coordination problems exemplified by the tragedy of the commons. (i) Briefly describe the tragedy of the commons and its relation to individual reactions during lockdowns. (ii) Create a payoff matrix for panic buying or mass gatherings and find the Nash equilibrium. Propose three strategies to eliminate panic buying and reach Pareto optimality.

The overall assessment will focus on understanding and presenting economic theories supported by evidence, clarity, conciseness, and the use of diagrams or mathematical derivations where appropriate. Proper referencing—preferably Harvard style—is essential. Presentation quality and clarity in mathematical and diagrammatic work significantly impact grading.

Introduction

The COVID-19 pandemic has had profound effects on economies worldwide, prompting a variety of policy responses aimed at mitigating economic damage. This essay explores these effects through the lens of economic theories and models, focusing on the short-term economic impacts and policy effectiveness, as well as the long-term consequences such as sovereign debt implications and unemployment dynamics. The analysis includes the application of macroeconomic models, game theory, and coordination problems, providing a comprehensive understanding of the economic disruptions caused by the pandemic.

Impact of COVID-19 on Indian Economy and Recovery Measures

India, with an already negative output gap prior to COVID-19, faced significant economic contractions due to the nationwide lockdown. The three-equation macroeconomic model—comprising the IS curve, LM curve, and the Phillips curve—offers insights into the short-term fluctuations in output, inflation, and unemployment. During the pandemic, the supply and demand shocks caused an inward shift of the IS curve (reduction in aggregate demand) and a deterioration in the Phillips curve (increase in unemployment and inflationary pressures). The Indian government’s fiscal stimulus, alongside Reserve Bank of India’s monetary easing, aimed to shift the IS curve outward and support aggregate demand (Misra & Kumar, 2020).

The fiscal stimulus included direct cash transfers, extension of credit lines, and support to vulnerable sectors, which are modeled as increasing autonomous spending. The monetary policy response, through interest rate cuts, lowered borrowing costs, stimulating consumption and investment. The combined effect theoretically raises the short-term output, moving the economy closer to potential output but may also lead to increased fiscal deficits and rising sovereign debt levels. This is represented in the model where the fiscal expansion shifts the IS curve outward, increasing output (Y) temporarily but raising public debt to GDP ratios, which may pose sustainability concerns in the long run (Kumar & Saini, 2020).

COVID-19 and Sovereign Debt Dynamics

The surge in fiscal deficits due to pandemic-related spending results in increased sovereign debt. As governments borrow to finance stimulus packages, debt-to-GDP ratios tend to rise sharply (IMF, 2020). For emerging economies like India, heightened borrowing can strain fiscal space, potentially leading to higher interest payments and debt servicing challenges. According to the World Bank (2021), India’s public debt rose from 70.4% of GDP in 2019 to approximately 89.6% in 2021, largely attributable to pandemic expenditures.

Moreover, increased sovereign debt can impact credit ratings and borrowing costs, leading to a feedback loop where higher borrowing costs further elevate debt levels. The sustainability of high debt levels depends on the country's economic growth and ability to generate revenue (Berg & Ostry, 2011). Managed properly, stimulus-induced debt can support recovery; mismanagement or prolonged downturns risk debt distress, underlining the importance of policy calibration amid crisis (IMF, 2020).

Effects of Pandemic on US and UK Economies: Output, Unemployment, and Inflation

The US and UK economies experienced sharp declines during the pandemic, particularly in sectors such as hospitality, travel, and retail, which saw unemployment skyrocket and output plummet. According to the Bureau of Labor Statistics (2020), US unemployment peaked at 14.8% in April 2020, while the UK's OBR forecast predicted a GDP shrinkage of up to 35%.

The output gap widened significantly as economic activity slowed, causing deflationary pressures initially due to decreased demand (Furceri et al., 2020). However, the expansive fiscal and monetary policies, including paycheck protection programs and interest rate cuts, aimed to close this gap post-pandemic. The Phillips curve suggests that unemployment and inflation are linked; in the crisis, high unemployment temporarily suppressed inflation, but as recovery ensues, inflation may rise, influenced by supply chain disruptions and stimulus spending (Blanchard et al., 2020).

In sectors like hospitality and transportation, job losses led to increased idle capacity and suppressed wages, causing a rise in unemployment. Conversely, sectors like e-commerce and technology experienced growth, exemplifying sectoral divergence during the crisis (Rogoff & Reinhart, 2020). The scarring effects may include prolonged unemployment and reduced labor force participation, which will influence the output gap and inflation trajectories well into the future.

Modeling Long-term Unemployment: The Diamond-Mortensen-Pissarides Framework

The Diamond-Mortensen-Pissarides (DMP) model provides insights into labor market dynamics, emphasizing search frictions and matching processes. COVID-19-induced disruptions increased the separation rate (from employment to unemployment) and reduced vacancy posting, causing a rise in the steady-state unemployment rate. The model predicts higher long-term unemployment due to increased mismatch between worker skills and available jobs, as firms reduce hiring or lay off workers for extended periods (Hagedorn, Manovskii, & Mitman, 2015).

The pandemic has led to sector-specific shocks, where certain industries face permanent structural changes, reducing the matching efficiency. Additionally, heightened uncertainty and risk aversion immobilize the labor market, increasing the duration of unemployment spells. The equilibrium unemployment rate, u*, increases as the real wage adjustments and frictional parameters evolve unfavorably, resulting in persistent unemployment (Pissarides, 2000).

Coordination Problems and the Tragedy of the Commons During Lockdowns

The tragedy of the commons describes a situation where individual rational behavior leads to overuse and depletion of a shared resource, resulting in suboptimal outcomes for all users. During lockdowns, individuals’ decisions to participate in panic buying or mass gatherings exemplify this dilemma; each person’s rational choice to secure resources out of fear amplifies the problem, leading to shortages and health risks (Hardin, 1968).

A simple payoff matrix for panic buying might involve two players (consumers). If both buy excessively, resources become scarce, and both are worse off; if neither buys excessively, resources are evenly distributed, and both benefit. The Nash equilibrium often involves overbuying, illustrating the tragedy.

To eliminate panic buying, policies such as rationing, increasing supply, and public information campaigns promoting cooperation can help. These measures align individual incentives with collective well-being, guiding outcomes toward Pareto efficiency (Ostrom, 1990).

Conclusion

The COVID-19 pandemic has exerted widespread economic effects, from shrinking output and surging unemployment to increased sovereign debt. Applying macroeconomic models provides a structured understanding of these phenomena, highlighting policy trade-offs and long-term risks. Coordination challenges like the tragedy of the commons highlight societal vulnerabilities in crises, emphasizing the importance of effective management and collective action. As economies recover, navigating these complex issues will require calibrated policies informed by sound economic theory and empirical evidence.
