<strong>Challenges</strong> <strong>in</strong> <strong>the</strong> <strong>Era</strong> <strong>of</strong> <strong>Globalization</strong><br />

Edited by Emmanuel Obuah<br />

Lnimp is log <strong>of</strong> rice imports, lnripric is <strong>the</strong> log <strong>of</strong> domestic price <strong>of</strong> rice, lnMaipro is <strong>the</strong> quantity <strong>of</strong> maize<br />

produced domestically, lnPopn is <strong>the</strong> log <strong>of</strong> midyear population , lnGDP is log <strong>of</strong> GDP per capita time is<br />

<strong>the</strong> time trend , is an error term which is assumed to be normally distributed with a zero mean and a<br />

constant variance.<br />

Results and Discussions<br />

The regression results are presented on table 3. From <strong>the</strong> results, <strong>the</strong> adjusted R 2 is 0.946 which implies<br />

that variables <strong>in</strong>cluded <strong>in</strong> <strong>the</strong> model expla<strong>in</strong> 95% <strong>of</strong> variation <strong>in</strong> import demand. After correct<strong>in</strong>g for<br />

autocorrelation, <strong>the</strong> D-W statistic <strong>of</strong> 2.17 was obta<strong>in</strong>ed imply<strong>in</strong>g that <strong>the</strong>re is no problem. The regression<br />

estimates on own import price <strong>of</strong> rice, <strong>the</strong> population, consumption variables are statistically significant<br />

and carry <strong>the</strong> expected signs. However, <strong>the</strong> quantity <strong>of</strong> maize produced has a negative expected, but not<br />

statistically significant. The estimated coefficient on GDP per capita variable carries an unexpected<br />

negative sign and not statistically significant.<br />

The results show that a 1 % <strong>in</strong>crease <strong>in</strong> import price <strong>of</strong> rice decreases <strong>the</strong> quantity <strong>of</strong> rice imports by<br />

0.35% reduction <strong>in</strong> rice imports. This means that as <strong>the</strong> rice import price <strong>in</strong>creases, it will have a positive<br />

impact on domestic rice production. Bamidele et al, (2010) found <strong>the</strong> same results for Nigeria. A 1 %<br />

<strong>in</strong>crease <strong>in</strong> quantity <strong>of</strong> rice produced domestically will lead to decrease <strong>of</strong> 1.99%<strong>of</strong> domestic production.<br />

In terms <strong>of</strong> population, a 1% <strong>in</strong>crease <strong>in</strong> population will lead to approximately 4.08% <strong>in</strong>crease <strong>in</strong> rice<br />

imports. This implies that domestic rice production will have to be <strong>in</strong>creased to meet <strong>the</strong> needs <strong>of</strong> <strong>the</strong><br />

<strong>in</strong>creas<strong>in</strong>g population given that Uganda is experienc<strong>in</strong>g one <strong>of</strong> <strong>the</strong> highest (3.2%) growth rate <strong>in</strong> Africa,<br />

if sav<strong>in</strong>gs <strong>in</strong> foreign exchange have to be realized.<br />
