CAIE IGCSE Economics 2.9.3 Causes of Market Failure Questions

Read the source material carefully before answering Question 1.

St. Kitts and Nevis is a small, two-island country in the Caribbean. The country's three main industries are tourism, financial services and agriculture. Tourists are attracted by the country's beaches, coral reefs, forts, rainforests and shipwrecks. However, if rainforests continue to be cut down and soil erosion continues to pollute the coral reefs, killing off marine life, tourism may be discouraged. The St. Kitts and Nevis Government is also concerned that the social costs of tourism exceed the private costs.

St. Kitts and Nevis's financial services include a growing banking sector. Among the country's commercial banks are a few foreign multinational companies (MNCs). These MNCs are attracted by the country's relatively high incomes, the absence of personal income tax and a relatively high literacy rate.

Some of the country's main agricultural products are carrots, onions, peanuts and sweet potatoes. In 2017, the St. Kitts and Nevis Government introduced a training scheme to raise the productivity of onion farmers.

Other important industries in St Kitts and Nevis include healthcare and fishing. Table 1.1 shows healthcare spending as a percentage of GDP and life expectancy in six selected countries in 2022.

The small size of St. Kitts and Nevis's fishing industry means that it imports large quantities of fish. The country's fishing boats are small and some lack up-to-date equipment. A larger fishing industry, with bigger boats, may bring a number of benefits to the country.

Changes in the structure and performance of industries in St. Kitts and Nevis may alter the country's price level. Between 2018 and 2020, the country experienced deflation. This affected people's purchasing power, saving and debts. It also affected the country's exports and firms' investment decisions.
