To ensure food security in the Savannah Region of Ghana, the Chief Executive of Northern
Development Authority (NDA) has proposed a ten (10) year investment in irrigation for the
agricultural sector. This project is to be implemented in all the districts of the Region. The
flow of annual gross benefits and costs of this proposed project are given in the Table below.
Table 1 Discounted resource flow for the project of in millions of Ghana cedis
Year Total costs (GHS) Total Benefits (GHS)
0 1000 0
1 100 0
2 45 90
3 98 120
4 64 132
5 64 148
6 95 103
7 80 100
8 122 155
9 99 161
10 86 902
Using a discount rate of 10% and conversion factors of 1.2 and 1.1 for every cost item and
every benefit item respectively, calculate the following indices of the project and comment on
your results:
(a) The Economic Benefit/Cost Ratio
(b) The Economic Net Present Value

During 2011 the inflation rate in Brazil was about 6.6% while in the U.S. it was about 3.3%. At the

Based on your knowledge of the flexible accelerator model of investment, suppose you have information on initial capital stock in year 2009 to be Ȼ10,000, and that desired capital stock is Ȼ80,000. If the factor by which firms plan to close the gap between desired capital stock and actual capital stock is 0.15, how many years will take for the firms to meet the desired capital stock?

According to the World Wildlife Fund (WWF), it takes 2700 litres of water to produce one T-shirt. Water is used not only to grow cotton but also to dye clothing. Cotton growers use pesticides and chemicals that pollute the water. The pesticides and chemicals that remain in the environment harm animals and plant life. The WWF has been working with governments to help reduce this pollution. It advises them to introduce more regulation and to fine companies that pollute. Clothing manufacturers argue that this will add to their costs and mean they will supply less.This may mean they employ fewer people and will help reduce water pollution as less clothing is being manufactured. Fines will punish those that pollute while also earning the government revenue it can use to clean up the pollution. The fines must also be large enough to persuade firms to stop polluting." evaluate the impact of the government introducing regulation and fines to reduce the external costs of clothing production in its country
