Bellara's central bank has an inflation target of 3%. After several years of above-target inflation, it raised the policy rate by two percentage points. The central bank stated that restoring credibility could prevent workers and firms from expecting continuously rising inflation.
Higher commercial-bank rates have reduced purchases of cars and housing. Several firms have cancelled investment projects because expected returns are now below borrowing costs.
Inflation has started to fall, but economic growth has slowed and unemployment has increased. The government is concerned about the trade-off between price stability and employment in the short run.
Exporters argue that higher interest rates have attracted financial inflows and appreciated Bellara's currency. This has lowered imported input prices but reduced export competitiveness.

Montara experienced rapid growth after a surge in consumer spending. Output rose above its sustainable level and labour shortages developed. The central bank raised interest rates to close the inflationary gap.
Six months later, export demand unexpectedly declined. Some economists warned that the earlier rate increases could deepen the slowdown because monetary policy operates with time lags.
The central bank stated that monetary policy is flexible because rates can be adjusted without passing a new government budget. It paused further increases and announced that rates could be reduced if demand continued to weaken.
Businesses welcome predictable inflation but report that expensive credit has delayed investment. The construction sector has already reduced employment.

Lydora has experienced rapid growth in household consumption and housing investment. Unemployment has fallen to 3.8%, while inflation has risen above the central bank's target. The central bank identifies price stability as an important monetary-policy objective.
The central bank increased its policy interest rate from 3% to 5%. Commercial banks subsequently increased mortgage and business-loan rates. Officials expect weaker consumption and investment to reduce aggregate demand, although the effects may take more than a year to appear.
Food and energy prices have also increased because of poor harvests and higher world oil prices. Some economists therefore argue that the inflation is partly cost-push and will not be removed directly by higher interest rates.
The central bank uses inflation targeting and aims for inflation of 2%, within a range of 1% to 3%. Heavily indebted households report that higher mortgage repayments have reduced their disposable income.

Norvia entered a recession after exports and business confidence declined. Firms postponed investment and unemployment rose. The central bank responded with expansionary monetary policy, reducing its policy rate from to .
Commercial banks lowered some lending rates, but many firms remained unwilling to borrow because they expected weak sales. Banks also tightened credit checks. The central bank stated that policy changes influence spending through a transmission mechanism involving borrowing, saving, consumption, investment and the exchange rate.
The lower interest rate reduced the reward for saving and caused Norvia's currency to depreciate. Exporters became more competitive, but imported fuel became more expensive.
The economy has substantial spare capacity. However, consumer confidence remains low and the policy rate is already close to zero, limiting the scope for further conventional rate cuts.

Estara's inflation has exceeded its target following strong household demand. The central bank adopted contractionary monetary policy, increasing the official interest rate in several small steps.
Most mortgages in Estara have variable interest rates. Higher repayments have reduced the disposable income of indebted households, while retired savers have received higher interest income. Retail sales have declined sharply.
The central bank argues that small changes make monetary policy incremental and easily reversible. It could lower the rate quickly if unemployment rises more than forecast.
Critics argue that the burden of tightening is uneven. Low-income mortgage borrowers spend a large proportion of income on housing, while wealthy households are more likely to own interest-bearing financial assets.

Calidia has a large current account deficit. Strong consumption has increased imports of vehicles and electronics. The central bank raised interest rates to reduce domestic demand and improve external balance.
Higher rates reduced consumer credit and investment. However, they also attracted short-term financial inflows, causing the calid to appreciate.
The appreciation made imported goods cheaper but Calidia's tourism and manufactured exports more expensive abroad. Export firms have reduced employment.
The central bank's main objective remains a low and stable rate of inflation. Officials argue that cheaper imported fuel will reduce inflation, while exporters argue that the policy may worsen the trade balance.

Arandia has experienced weak consumption, falling investment and very low inflation. The central bank cut its policy rate to 0.1%, but aggregate demand remained weak. The economy has a recessionary gap and high cyclical unemployment.
Households increased saving because they feared job losses. Firms did not borrow despite cheap credit because they expected poor sales. Commercial banks were cautious about lending to small businesses.
Economists describe this as the near-zero lower bound constraint: there is little practical scope for reducing nominal interest rates further. The central bank continues to promise low rates, hoping to improve confidence.
Critics argue that monetary policy cannot force pessimistic households and firms to spend. Others note that low rates have depreciated Arandia's currency, supporting tourism and exports.

Selucia's central bank cut its policy interest rate after unemployment increased. Commercial-bank lending rates fell quickly, but household spending responded only gradually. The delay between a policy decision and its effect on output and inflation is called a time lag.
Businesses initially postponed investment because confidence was weak. Six months later, orders and borrowing began to rise. The central bank expects aggregate demand to strengthen further next year.
Selucia now has less spare capacity and house prices are increasing rapidly. Some policymakers fear that keeping rates low for too long could create an inflationary gap.
Others emphasize that monetary policy is easily reversible: the policy rate can be raised if inflationary pressure becomes excessive. However, an early increase could stop the recovery before employment has fully recovered.

Pelagos experienced rapid growth in mortgage borrowing and house prices while interest rates were low. Construction and consumption increased because homeowners felt wealthier. The central bank became concerned that excessive spending would increase inflation.
It raised the interest rate, and commercial banks increased mortgage rates. New housing demand declined, construction slowed and households with variable-rate mortgages reduced other spending.
The central bank seeks low inflation, low unemployment and a stable environment for long-term growth. These objectives may conflict when policy changes aggregate demand.
Housing construction employs many lower-skilled workers. A sharp slowdown could create cyclical unemployment, while stable inflation could reduce uncertainty and support sustainable investment over time.

Vardena imports most of its energy. A global supply disruption doubled the world price of gas, increasing firms' transport and production costs. Inflation rose well above target even though domestic demand was weak. This is described as cost-push inflation.
The central bank raised interest rates to prevent inflation expectations from becoming embedded. Officials accepted that policy could not create more gas but argued that it could limit second-round increases in wages and prices.
Higher borrowing costs have reduced investment and housing demand. Unemployment has increased, and small firms report difficulty refinancing debt.
The currency appreciated after the rate increase, making imported energy cheaper in domestic currency. The bank must decide whether the improvement in price stability justifies weaker output and employment.

Kintara's currency depreciated after world interest rates rose and investors moved funds abroad. Imported food and machinery became more expensive, increasing inflation. The central bank raised domestic rates to attract financial inflows and support exchange-rate stability.
Higher rates reduced consumption and investment. Manufacturers that borrow to buy machinery have postponed expansion, while the stronger currency has reduced imported input costs.
The central bank also aims to achieve low unemployment, but unemployment is already increasing. Exporters benefit from a weaker currency and fear that appreciation will reduce their competitiveness.
Economists disagree about whether monetary policy should prioritize inflation and the exchange rate or domestic output and employment. The outcome may depend on investors' confidence and changes in foreign interest rates.

Dorsia is recovering from a recession. Consumer spending has increased, but business investment remains weak and unemployment is still high. The central bank has kept interest rates low to promote a stable environment for long-term economic growth.
Inflation has moved above target following floods that damaged crops and raised food prices. The central bank must decide whether to increase rates despite the weak labour market.
Dorsian households have high variable-rate debt. Environmental damage has reduced food supply, while low business confidence limits investment. These economic, social and environmental factors are interdependent and affect monetary-policy outcomes.
Supporters of tightening emphasize inflation expectations and price stability. Opponents argue that higher rates would reduce demand without restoring damaged crops and would impose heavy costs on indebted households.

A disruption to global energy supplies has sharply increased Estavia’s production and transport costs. Headline inflation is well above target, but real output is below potential. Estavia’s central bank is considering increasing its policy interest rate.
Selected macroeconomic and household data for Estavia
| Indicator | Value |
|---|---|
| Headline inflation | |
| Underlying demand-related inflation | |
| Inflation target | |
| Actual real GDP | 686 billion estars |
| Potential real GDP | 700 billion estars |
| Initial nominal policy rate | |
| Proposed nominal policy rate | |
| Initial variable mortgage rate | |
| Proposed variable mortgage rate | |
| Representative mortgage balance | 200 000 estars |
A representative household has a variable-rate mortgage balance of 200 000 estars. Assume, only for the mortgage calculation, that the annual interest charge equals the stated mortgage rate multiplied by the outstanding balance.
Using headline inflation, calculate the approximate real policy interest rate before and after the proposed increase.
Calculate the increase in the representative household’s annual mortgage-interest charge if the mortgage rate rises from 4.0% to 6.5%.
Draw an AD/AS diagram to illustrate the initial impact of the global energy-supply disruption on Estavia’s average price level and real output.
Explain why a contractionary monetary policy cannot directly remove the main cause of Estavia’s headline inflation.
Explain how the proposed interest-rate increase may affect Estavia’s exchange rate and external balance.
Using the text/data provided and your knowledge of economics, recommend whether Estavia’s central bank should increase its policy interest rate from 2.5% to 5.0%.
Carvia has experienced strong domestic demand, inflation above target and a current account deficit. Its central bank has raised its policy interest rate and is considering selling government securities to reduce bank reserves.
Macroeconomic and exchange-rate data for Carvia.
| Indicator | Value |
|---|---|
| Inflation rate | per year |
| Inflation target | per year |
| Policy interest rate after increase | per year |
| Actual real GDP | 618 billion carvs |
| Potential real GDP | 600 billion carvs |
| Current account balance | of GDP |
| Initial exchange rate | |
| Exchange rate after rate increase |
Proposed open-market sale by Carvia’s central bank.
| Item | Value |
|---|---|
| Government securities to be sold | 1.2 billion carvs |
| Commercial-bank reserves withdrawn | 1.2 billion carvs |
| Minimum reserve requirement |
Assume for the deposit calculation that commercial banks lend all excess reserves, all loans are redeposited, banks hold no voluntary excess reserves and the public holds no additional cash.
Using Table 1, calculate Carvia’s approximate real policy interest rate after the increase.
Calculate the percentage appreciation of the carv against the US dollar.
Using Table 2, calculate the maximum contraction in bank deposits that could result from the proposed sale of government securities.
Draw a money-market diagram to illustrate the effect of the proposed open-market sale on Carvia’s equilibrium interest rate.
Draw an AD/AS diagram showing contractionary monetary policy closing Carvia’s inflationary gap.
Explain how Carvia’s higher interest rate and currency appreciation may affect its current account balance.
Using the text/data provided and your knowledge of economics, recommend whether Carvia’s central bank should proceed with the proposed open-market sale to address inflation and the current account deficit.
