Elections do not take place on the pages of academic books but in the real world, and for this reason the choice of any electoral system is, to some degree, dependent on the cost and administrative capacities of the country involved. Although donor countries often provide substantial financial support for the first, and even the second, election in a country in transition to democracy, this is unlikely to be available in the long term even if it were desirable.
A sustainable political framework takes into account the resources of a country both in terms of the availability of people with the skills to be election administrators and in terms of the financial demands on the national budget.
For example, a poor country may not be able to afford the multiple elections required under a Two-Round System or be able easily to administer a complicated preferential vote count.
However, simplicity in the short term may not always make for cost effectiveness in the longer run. An electoral system may be cheap and easy to administer but it may not answer the pressing needs of a country—and when an electoral system is at odds with a country’s needs the results can be disastrous.
Alternatively, a system which appears at the outset to be a little more expensive to administer and more complex to understand may in the long run help to ensure the stability of the country and the positive direction of democratic consolidation.
