Palm oil is labour intensive. Both nations experience increasing costs in their production. Explain the basis of and gains from trade for both countries using well drawn diagrams. [15 marks] 7 QUESTION 5 Palm oil is produced and consumed in Nigeria. The autarky price of palm oil is N100, Nigeria producers of palm oil produce 500 tons of palm oil and consumers consume 500 tons of palm oil. The free trade price of palm oil is N20. To protect domestic production and jobs, the Nigerian government imposes a 20 percent ad-valorem tariff on imported palm oil. Using partial equilibrium analysis and a well-drawn diagram, explain the impact of this policy decision. [10 marks] International trade is an important driver of economic growth for developed and developing countries alike. There are numerous measures used to examine or measure how a country performs when it comes to trade. This question is based on one of those measures. 1. Define Terms of Trade (TOT) [1 marks] 2. How is the Terms of Trade measured [2 marks] 3. Briefly explain what an improvement or decline in the Terms of Trade means [4 marks] Use the following link to access data from the UN Trade and Development (UNCTAD) database: Collect and download (in excel) Terms of Trade Index data series for the years 2005 to 2024 for the following regions: (i) Africa (ii) Americas (iii) Asia (iv) Europe (v) Oceania 4. Plot the data obtained above in one line diagram (you will have 5 lines representing each region). The figure must be correctly labelled with Terms of Trade Index on the vertical axis and years on the horizontal axis. The title of the figure should be above the figure, and the source should be below the figure [10 marks]. 5. In no more than one (1) page, discuss briefly, but concisely, the trend in the data series for the regions in question. Your discussion must speak to the peaks and troughs in the data.
