Monetary policy is often a very effective way of reducing inflation, because a central bank can raise interest rates and tighten the money supply in order to reduce aggregate demand. Inflation is a sustained increase in the general price level, and monetary policy refers to central bank actions over interest rates and

A change in supply alters both the size of total welfare and the distribution of welfare between consumers and producers. Consumer surplus (CS) is the difference between what consumers are willing to pay and what they actually pay, while producer surplus (PS) is the difference between the market price and the minim

Consumers are rational in economic theory if they maximise utility given prices, income and preferences. Under the rational choice model, this implies consistent choices and a demand curve that reflects deliberate optimisation: when price falls, quantity demanded rises, ceteris paribus. In practice, however, behavioura

In a market economy, prices act as signals and incentives. They communicate information about relative scarcity to buyers and sellers, and they encourage behaviour that moves the market towards equilibrium. Excess demand and excess supply therefore indicate that the current market price is not the equilibrium price and

The most appropriate policy recommendation is a contractionary monetary policy, specifically a rise in interest rates by the central bank, supported by limited fiscal restraint. This is the best response because Ghana’s inflation rate has risen very sharply from 12.5% in 2021 to 25.0% in 2022 and to an estimated 31.5%

Differing normative judgements often lead to different policy responses to market failure because economics can explain that a welfare loss exists, but it cannot by itself decide what governments ought to prioritise. Positive analysis may show that negative externalities such as pollution or smoking lead to overprodu

Pollution in the River Delta is a clear example of a negative externality of production, where manufacturing plants impose external costs on third parties such as fishermen, farmers and local residents. In this case, the marginal social cost (MSC) of production is greater than the marginal private cost (MPC), so the ma

Simultaneous shifts in demand and supply occur when non-price determinants of both curves change at the same time. The impact on equilibrium therefore depends not only on the direction of the shifts, but also on their relative magnitudes and on the price elasticity of demand and supply. As a result, some outcomes are d

Georgia’s free trade policies are likely to support both economic growth and economic development, but the effects are not automatically positive or evenly shared. Economic growth means an increase in real output, while economic development is broader, including improvements in living standards, employment, equality an

Kuwait’s diversification strategy is important because the economy appears to be highly dependent on oil, so fluctuations in oil prices can strongly affect national income, employment and government revenue. A strategy of diversification aims to reduce this dependence by expanding other sectors, attracting foreign dire

Consumer heuristics are mental shortcuts used to make decisions quickly when information is limited or costly to process. In a market context, this means consumers may not behave like fully informed, rational agents. As a result, demand can diverge from what would occur if consumers compared all prices and qualities pe

Kuwait’s diversification strategy appears to be moderately effective in promoting both economic growth and development, but its success is still limited by the continued dominance of oil. Economic diversification means broadening the range of output and exports away from a single product, while economic development is

Brazil’s Green Growth Plan is likely to have a positive impact on both economic growth and development, but the size of that impact depends on whether Brazil can manage the short-run costs and distribute the benefits widely. Economic growth refers to an increase in real output, while development is broader and includes

Turkey’s ability to balance short-term stimulus with long-term development objectives is limited but not impossible. In the short run, policies such as lower interest rates and subsidies on “electricity and staple foods” can support aggregate demand and protect vulnerable households. However, the data suggest that if t

Zimbabwe’s policy mix could reduce poverty and promote sustainable development, but only to a moderate extent unless it is supported by much greater macroeconomic stability. Poverty can be defined as a situation in which people lack sufficient income and resources to achieve a basic standard of living, while sustainabl

Economic growth is an increase in real GDP over time, while economic development is broader, including improvements in living standards, poverty reduction and better access to services such as health and education. Agricultural subsidies are government payments or price supports that reduce farmers’ costs or protect th

A recessionary gap exists when actual real output is below potential output, so there is spare capacity, cyclical unemployment and weak aggregate demand. Monetary policy refers to actions by the central bank to influence interest rates, credit conditions and the money supply in order to affect aggregate demand. In prin

Interventionist supply-side policies are government measures to improve the quantity and quality of factors of production, for example through spending on education, training and infrastructure. Their main aim is to raise productive capacity, but they can also reduce unemployment, especially structural unemployment, wh

Indirect taxation can be an effective government response to the overuse of common pool resources, but its success depends heavily on the nature of demand, enforcement, and whether it is combined with other policies. A common pool resource is non-excludable but rivalrous, meaning people cannot easily be prevented from

Policies to reduce income inequality can reduce relative poverty to a considerable extent, but their effectiveness depends on how they are designed and on wider labour-market conditions. Relative poverty refers to being poor compared with the typical household in a country, so it is usually measured against a poverty l

Structural unemployment is unemployment that occurs when there is a mismatch between the skills, location or occupational patterns of workers and the jobs available in the economy. It is therefore usually longer term, because unemployed workers may need retraining or relocation before they can find work.

Georgia’s fre

Demand-pull inflation occurs when aggregate demand (AD) rises beyond the economy’s full employment level of output, creating an inflationary gap and upward pressure on the general price level. Contractionary fiscal policy means reducing government expenditure and/or increasing taxation to shift AD leftwards. Monetary p

Taiwan’s heavy reliance on its high-tech export industry can be a powerful engine of long-term growth, but it also creates significant vulnerabilities. High-tech exports are goods produced using advanced technology and substantial research and development, and in Taiwan this sector is clearly central because electronic

Subsidies are government payments that reduce the price of a good below the market level, while targeted cash transfers are direct payments to selected low-income households. Economic growth refers to an increase in real output, whereas economic development is broader, including lower poverty and inequality and improve
