Conflicts between low unemployment and low inflation

Macroeconomic policies aimed at achieving low unemployment can often lead to higher inflation, while those targeting low inflation may increase unemployment. This trade-off is a key challenge in economic management.

Policy impacts on unemployment and inflation

• Expansionary policies - Expansionary fiscal or monetary policies, such as increased government spending or lower interest rates, boost aggregate demand to reduce unemployment but can cause demand-pull inflation as prices rise.
• Contractionary policies - Tight monetary policy (e.g., higher interest rates) or contractionary fiscal policy (e.g., reduced spending) helps control inflation but risks increasing cyclical unemployment by slowing economic activity.

The short-run Phillips curve

The short-run Phillips curve illustrates an inverse relationship between unemployment and inflation, particularly in higher-level (HL) analysis.

Key implications:

• With an upward-sloping Monetarist short-run aggregate supply (SRAS) curve or the middle upward-sloping section of a Keynesian aggregate supply (AS) curve, increases in aggregate demand raise real gross domestic product (GDP) and lower unemployment but also increase the price level, leading to inflation.
• Research indicates that inflation accelerates when unemployment falls more than one percentage point below a country's natural rate of unemployment (NRU), which represents the lowest unemployment rate achievable without accelerating inflation.
• The NRU is not fixed and can decrease over time due to factors like improved labour market efficiency.

Conflicts between high economic growth and low inflation

Pursuing high economic growth through rising aggregate demand can generate inflationary pressures, especially as the economy approaches full capacity. Effective policy requires balancing these objectives.

Causes of inflationary pressures from growth

• The Keynesian AS curve slopes upward due to bottlenecks in the economy, where not all sectors reach full employment at the same time.
• As aggregate demand increases, capacity constraints create shortages in resources like labour or materials, pushing up prices.
• The closer the economy operates to its potential output (full employment), the more likely further growth will cause inflation to accelerate.
• Policymakers face uncertainty, as they cannot predict exactly when additional growth will trigger rising inflation; premature tightening of monetary policy may control inflation but unnecessarily extend high unemployment.

Role of supply-side policies in resolving the conflict

• Successful supply-side policies can enable economic growth without inflation by increasing the economy's productive capacity.
• These policies shift the long-run aggregate supply (LRAS) curve to the right, allowing aggregate demand to rise without increasing the price level.
• Examples include investments in education, infrastructure, or technology to boost productivity and efficiency.

Conflicts between high economic growth and environmental sustainability

Economic growth can harm the environment through resource depletion and pollution, but it can also enable investments in sustainable practices. Balancing these requires targeted policies.

Environmental effects of growth

• Economic growth often requires natural resources and generates emissions and waste, potentially exceeding the Earth's carrying capacity.
• The environmental Kuznets curve suggests that as per capita incomes rise with growth, pollution initially increases but then decreases after a critical income level, as wealthier societies invest in cleaner technologies.
• This curve may apply mainly to local externalities (e.g., air quality in cities) rather than dispersed ones like global carbon emissions.

Policies to promote sustainable growth

Governments can implement measures to make growth more environmentally friendly:

• Reducing harmful subsidies - Cease subsidies for fossil fuels or activities that deplete common pool resources, such as overfishing.
• Regulatory and market-based tools - Introduce stricter environmental regulations, carbon taxes, or cap-and-trade schemes to limit emissions and encourage cleaner practices.
• Investments in green technologies - Provide subsidies for firms adopting clean production methods and fund research into sustainable innovations.
• Shifting production - Encourage a reduction in pollution-intensive goods and the adoption of cleaner technologies to support long-term sustainability.

Conflicts between high economic growth and equity in income distribution

While economic growth can provide resources for redistribution, it often exacerbates income inequality if benefits are not shared widely. Inclusive growth is essential for long-term stability.

How growth affects income distribution

Economic growth can both improve and worsen equity.

Positive effects through redistribution:

• Growth enables direct redistribution via social welfare systems, such as pensions or unemployment benefits.
• It supports indirect measures like poverty alleviation programmes focused on agricultural productivity, infrastructure, health, and education.

Negative effects leading to inequality:

• Income inequality has risen in many growing economies.
• Growth may not be inclusive if it is driven by only a few industries, concentrated in specific regions, reliant on particular skills, or results in jobless growth (where output rises without creating employment).

Implications for economic resilience

• Non-inclusive growth, where benefits accrue mainly to the wealthiest, is less resilient and sustainable.
• The distribution of growth benefits determines its longevity; in unequal societies, policies to revive the economy may lack broad support if long-term gains are not shared evenly.
