The Hong Kong dollar operates under a linked exchange rate system. Which statement best describes the main implication for monetary policy?(1 分)

The authorities can freely set any interest rate independently of conditions affecting the US dollar without pressure on the link.

Maintaining the link constrains monetary autonomy, so local interest rates are influenced by the need to defend the exchange-rate arrangement.

The link guarantees that Hong Kong's inflation rate always equals that of the United States.

The link prevents all changes in Hong Kong's money supply.

A policy that prevents workers from moving between occupations.

頁次：16

題目 40

A government plans a large infrastructure programme during a period of high public debt and near-full employment. Which assessment is most reasonable?(1 分)

raise the domestic price, increase domestic production and reduce domestic consumption of the good.

lower the domestic price and increase imports.

leave the domestic price unchanged because the country is small.

raise world supply and guarantee a net gain in national welfare.

題目 43

If the Hong Kong dollar appreciates against another currency, other things being equal, which effect is most likely?(1 分)

Hong Kong exports become cheaper to foreign buyers and imports become more expensive to Hong Kong buyers.

Hong Kong exports become more expensive to foreign buyers and imports become cheaper to Hong Kong buyers.

Both exports and imports become cheaper to Hong Kong residents.

The exchange-rate change has no possible effect on trade flows.

頁次：18

題目 44

A country's current account records a deficit in a particular year. Which statement is correct?(1 分)

The country must have had a government budget deficit in the same year.

Its recorded current-account payments exceed receipts, but this alone does not establish that the deficit is unsustainable or undesirable.

Its exports of goods must exceed its imports of goods.

It has no capital or financial account transactions.

題目 45

An economy's currency depreciates. Its export demand is price elastic and its import demand is price inelastic in the short run. Which conclusion is most appropriate, other things being equal?(1 分)

The value of exports is likely to rise and the value of imports is likely to rise, so the trade balance must improve immediately.

Export quantities may respond substantially, while import quantities respond less; the value of the trade balance need not improve immediately and may follow a J-curve pattern.

Export quantities must fall because foreign buyers pay fewer units of the depreciating currency.

The trade balance must remain unchanged because depreciation affects only financial transactions.

32: A. Lending can create a deposit, which is part of the money supply; the extent is constrained by capital, liquidity, risk, regulation and demand for loans.

第 40 題1 分

正確答案： B

40: B. Well-selected infrastructure may improve productivity and potential output, but project appraisal must compare social benefits with resource and financing costs.

第 41 題1 分

正確答案： B

41: B. A's opportunity cost of one rice is 0.5 textile, compared with B's 1 textile, so A has comparative advantage in rice. A's cost of one textile is 2 rice, compared with B's 1 rice, so B has comparative advantage in textiles. A and C confuse absolute productivity with comparative advantage; D is false. A1 for B.

第 42 題1 分

正確答案： A

42: A. In a small country, the world price is given; the tariff raises the domestic price, encouraging domestic supply and reducing domestic demand, so imports fall.

43: B. Appreciation raises the foreign-currency price of Hong Kong exports and lowers the Hong Kong-dollar price of imports, other things equal. A reverses both effects; C does not distinguish the buyer's currency; D ignores relative-price effects. A1 for B.

第 44 題1 分

正確答案： B

44: B. A current-account deficit means current-account debits exceed credits. Its implications depend on causes, financing, sustainability and the wider economy. A confuses the fiscal and external balances; C refers only to goods and gives the wrong necessary condition; D is false because balance-of-payments accounts have offsetting financial flows and other entries. A1 for B.

第 45 題1 分

正確答案： B

45: B. Depreciation makes exports relatively cheaper and imports dearer. Elastic export demand allows a comparatively large quantity response, while inelastic import demand limits its short-run reduction; contract and price adjustments can delay improvement in the trade balance, producing a possible J-curve. A overstates certainty and mishandles values; C reverses the likely export response; D ignores trade-price effects. A1 for B.
