2 N18 3 ECONO HP2 ENG TZ0 XX Section A Answer one question from this section 1 Study the following extract and data and answer the questions that follow South Sudan joins the East African Community The East African Community EAC is the most integrated trading bloc in Africa In 2005 the members established a customs union and then in 2010 it became a common market There are ambitious plans to establish a monetary union by 2024 According to a recent report the region is wealthier and more peaceful as a result of the increased integration Economic models suggest that bilateral trade between member countries was 213 higher in 2011 than it would have been without the integration This is despite the fact that progress on fully eliminating trade barriers has been rather slow and there are still a large number of non tariff barriers Until recently the customs union was made up of Burundi Kenya Rwanda Tanzania and Uganda Very recently South Sudan joined the bloc This presents a tremendous opportunity for South Sudan which was recently recognized as an independent country South Sudan is one of many developing countries that are dependent on oil exports for the majority of its export revenues and oil prices have been falling due to increased supply of oil in the market The deteriorating terms of trade have resulted in a worsening of the current account and lower government revenues Regional economic integration might help South Sudan to diversify its economy Agriculture is one potential area that South Sudan could focus on to diversify its economy According to some estimates 70 of land is suitable for agriculture but less than 4 is currently being cultivated The large flood plains in the country are suitable for rice production and the hope is that South Sudan can develop a comparative advantage in this essential food South Sudan is landlocked and most of its road network is unpaved This is just one example of its poor infrastructure Since infrastructure is an expensive investment regional cooperation will be vital for improving its road systems Furthermore effective transport links to sea ports in Kenya and Tanzania will allow for greater trade and therefore economies of scale In the short term there will be challenges for South Sudan associated with joining the common market For example before Rwanda joined the EAC in 2007 there were lower tariffs on many imported inputs However the cost of living for the poor population rose because of trade diversion that occurred after joining the EAC South Sudan is likely to face the same problem Labour costs in South Sudan are higher than those of other member countries and years of conflict have left the population with low levels of education and skills This may present a barrier for South Sudan in attracting foreign direct investment despite being part of the common market This question continues on the following page

3 N18 3 ECONO HP3 ENG TZ0 XX M Notes for examiners 1 Whenever relevant carry over marks must be awarded If a candidate makes an error in calculation but then uses the incorrect figure appropriately and accurately in later question parts then the candidate may be fully rewarded This is the own figure rule and you should put OFR on the script where you are rewarding this 2 Alternative approaches may be taken in responses to the 4 questions that use A02 command terms If this is the case and the alternative approaches are valid then full credit should be given 1 a i Calculate Firm A s average fixed costs when it is producing 125 cartons of coffee per month 2 500 125 Identification of FC at 500 or any valid working is sufficient for 1 4 An answer of 4 or 4 without working is sufficient for 1 ii Calculate Firm A s average variable costs when it is producing 125 cartons of coffee per month 2 1500 125 Identification of VC at 1 500 or any valid working is sufficient for 1 12 An answer of 12 or 12 without working is sufficient for 1 b i Using Figure 2 calculate the average fixed costs when 80 cans per month are produced 25 20 5 An answer of 5 is sufficient for 1 1

6 d Sometimes a firm continues to produce in the short run even when it is making an economic loss Explain why the firm might choose to do this Level 0 1 2 e The work does not meet a standard described by the descriptors below There is limited understanding For a response that the price is above the shut down price minimum AVC OR the firm is covering its variable costs There is clear understanding For a response that in the short run the firm should continue to produce provided price covers average variable costs since it is making a contribution to fixed costs OR the firm s losses are less than its fixed costs so its losses would be greater if it shut down 2 Marks 0 1 2 Outline why a perfectly competitive firm is a price taker Level 0 1 2 f N18 3 ECONO HP3 ENG TZ0 XX M The work does not meet a standard described by the descriptors below There is limited understanding For a response that it does not have market power and so must accept the market price There is clear understanding If the firm raises the price both its quantity sold and revenue will drop to zero there is also no benefit from lowering its price since it can sell any amount at the market price 2 Marks 0 1 2 Firm B and all the other firms in the tea market begin to sell their tea in distinctive packages and many differentiate their product with organic tea or fruit flavours Explain how the demand curve faced by Firm B will change as a result Level 0 1 2 The work does not meet a standard described by the descriptors below There is limited understanding For a response that the demand curve will now slope down There is clear understanding For a response that the demand curve will slope down because the firm now has the market monopoly power or the ability to be a price maker OR that the demand curve will slope down because it is now a monopolistic competitor OR the firm s demand curve is no longer perfectly elastic because it now has the market power to change its price Marks 0 1 2 2
