The results show that the average income, tariff rate and the number of stores where energy bars are offered significantly influence the annual average demand of energy bars per person. The regression model is statistically significant as shown by the value for F statistics. Among these variables, a one unit rise in the logarithm of the number of stores where energy bars are offered results of 0.92 units rise in the logarithm of annual average demand of energy bars per person. In other words, a one unit rise in the number of stores where energy bars are offered results in a significant rise of 8.32 units in the annual average demand of energy bars per person. This shows that offering the products at another store will result in more than proportionate rise in the annual average demand of energy bars per person. The results also show that one unit rise in the average income results in a significant rise of 4.58 units rise and one unit rise in the tariff rate results in a significant decline of 2.7 units in the annual average demand of energy bars per person.
I.Problem B:
In the above figure, it is shown that by imposing a tariff the domestic producers benefit as is shown by the area denoted as producer surplus. The reason is that they can charge a higher price for the product, which, in turn increase the revenue of the sellers and the tax revenue for the government (Pindyck and Rubinfield, 2012). At the same time, consumers have to pay a price greater than the world price thus increasing the prices which the consumers have to pay for buying the imported good. Over time, there will be a decline in the consumer demand for the imported goods, which is the demand for energy bars in this case. There will be a deadweight loss when the consumers buy the imported product since the consumer surplus which they were enjoying is declined (Varian, 2010). The overall surplus to the economy will decline through imposing the tariffs by the deadweight loss from imposing the tariff. The deadweight loss is the reduction in consumer surplus which is not able to be compensated by the gain in the producer surplus. Thus, the free trade agreement by eliminating the tariffs can increase the consumer surplus which in turn increases the surplus to the economy.
The GDP of the industry is increased through the rise in the labour demand and rise in the wages, which were explained earlier. The economy as a whole will be affected positively due to the rise in the industria’s GDP .It can also cause high inflation due to the increased income of the population.
