TAXATION, INVESTMENT, AND GROWTH 2-13<br />

studies or survey results, but <strong>of</strong>ten rich <strong>in</strong> detail. One <strong>of</strong> <strong>the</strong> earliest reviews <strong>of</strong> fiscal<br />

<strong>in</strong>centives <strong>in</strong> develop<strong>in</strong>g countries (Shah <strong>and</strong> Toye 1978) set <strong>the</strong> stage by cit<strong>in</strong>g three studies<br />

<strong>in</strong> Mexico, Jamaica, <strong>and</strong> Pakistan, which showed that most <strong>in</strong>vestment decisions were not<br />

affected by tax considerations. Ano<strong>the</strong>r study on Brazil, however, showed that <strong>in</strong>vestment <strong>in</strong><br />

<strong>the</strong> nor<strong>the</strong>ast region did depend critically on tax benefits.<br />

Not much has changed s<strong>in</strong>ce that early review <strong>of</strong> <strong>the</strong> case-study literature. Most case studies<br />

assign tax considerations an <strong>in</strong>significant role (as long as <strong>the</strong> tax system is reasonably well<br />

structured), <strong>and</strong> emphasize <strong>the</strong> role <strong>of</strong> non-tax factors <strong>in</strong> <strong>in</strong>vestment decisions. In some cases,<br />

such as Mauritius <strong>and</strong> Irel<strong>and</strong>, generous tax <strong>in</strong>centives have undoubtedly lured <strong>in</strong>vestors.<br />

And <strong>in</strong> o<strong>the</strong>rs, such as Ug<strong>and</strong>a <strong>and</strong> Indonesia, <strong>the</strong> elim<strong>in</strong>ation <strong>of</strong> <strong>in</strong>centives had no effect on<br />

<strong>the</strong> flow <strong>of</strong> <strong>in</strong>vestment—provid<strong>in</strong>g real-world “experiments” to prove that selective<br />

<strong>in</strong>centives are not needed if <strong>the</strong> underly<strong>in</strong>g <strong>in</strong>vestment climate is attractive. So case study<br />

evidence can be used to support just about any conclusion.<br />

2.4 Lesson for <strong>SADC</strong><br />

The ma<strong>in</strong> lesson for <strong>SADC</strong> from <strong>the</strong> empirical literature on determ<strong>in</strong>ants <strong>of</strong> <strong>in</strong>vestment is that<br />

taxation does affect some <strong>in</strong>vestments <strong>in</strong> some circumstances, but <strong>in</strong> general it is not a<br />

primary consideration for <strong>in</strong>vestors. The context matters. In present<strong>in</strong>g case studies on FDI <strong>in</strong><br />

Africa, Basu & Sr<strong>in</strong>ivasan (2002) clarify this po<strong>in</strong>t by classify<strong>in</strong>g <strong>in</strong>vestments <strong>in</strong>to four<br />

categories:<br />

1. Investment <strong>in</strong> natural resources<br />

2. Investment triggered by locational advantages<br />

3. Investment triggered by broad-based economic reforms<br />

4. Investment triggered by <strong>the</strong> provision <strong>of</strong> specific <strong>in</strong>centives.<br />

Implicit <strong>in</strong> <strong>the</strong>ir analysis is that <strong>the</strong> fourth group—<strong>in</strong>vestment attracted by specific <strong>in</strong>centives<br />

—is <strong>the</strong> exception ra<strong>the</strong>r than <strong>the</strong> rule.<br />

To <strong>the</strong> extent that taxation does affect <strong>in</strong>vestment, it is important to bear <strong>in</strong> m<strong>in</strong>d that <strong>the</strong> tax<br />

burden can be reduced <strong>in</strong> two ways: by mak<strong>in</strong>g <strong>the</strong> general tax system more attractive, or by<br />

<strong>of</strong>fer<strong>in</strong>g selective <strong>in</strong>centives. The empirical literature provides no clear guidance about which<br />

approach is preferable. On <strong>the</strong> one h<strong>and</strong>, some econometric evidence suggests that carefully<br />

targeted <strong>in</strong>centives are more cost-effective than general tax reductions. On <strong>the</strong> o<strong>the</strong>r h<strong>and</strong>,<br />

some survey results <strong>and</strong> case studies <strong>in</strong>dicate that <strong>the</strong> overall tax system is much more<br />

important to <strong>in</strong>vestors than specific <strong>in</strong>centives. It is time, <strong>the</strong>n, to focus our attention on <strong>the</strong><br />

economics <strong>of</strong> tax <strong>in</strong>centives as such.
