ABSTRACT
The study analyzed imports revenue contributions from six high-risk
commodities obtained from the Inspection and Control Services Company at
Tema port. The six items were Auto-parts, Rice, Computers and Accessories,
Household Electricals, Poultry Products and Used Clothing. The data covered five
years from 2004 to 2008. The objective was to obtain revenue estimates of these
six items. Another objective was to provide forecasts of yearly total revenue
based on the five years revenue data. In order to achieve these objectives, dummy
variable regression model and trend model were used.
Initial exploration of the data revealed that the revenue contribution of the
six items increased with increasing line items. It was observed that even though
the line item of rice was the least in the period, it contributed the highest to
revenue. The dummy variable model involved only three of the six initially
selected items. These three variables, which are Auto-parts, Rice, and Household
Electricals, were found to contribute significantly to the total revenue from the six
items. The model explained 86 percent of variation in revenue from the three
items.
Using a linear trend model, it was found that the average yearly total
revenue from import was expected to increase by an amount of $8,761,463.00
each year. By this pattern, the total yearly import revenue in 2011 was expected to
reach $129,600,314.00.
The findings of this study show that an outright ban on Auto-parts, Rice,
and Household Electricals, would not be in the interest of revenue mobilization.
